Occupational complexity of paid work and housework, and its impact on the cognitive performance in community dwelling older adults, preliminary results / Complexidade ocupacional do trabalho remunerado e o trabalho doméstico e seu impacto no desempenho cognitivo de idosos residentes na comunidade, resultados preliminares

ABSTRACT Work and activity could be an important source of cognitive enrichment. Activities that are more challenging concerning the cognitive functions that are put into practice are associated with lower risk of cognitive decline in old age. Objective: The present study aimed to assess the impact of occupational complexity and household tasks in three cognitive domains (verbal episodic memory, language, and executive functions) in older adults residing within the community. Methods: A trail analysis was executed, using the structural equations procedure in 120 participants assessed with main lifetime occupational activity and household tasks questionnaire, as well as a neuropsychological assessment battery for memory, language, and executive functions. Results: The regression weights analysis indicated that complexity in household chores showed moderate effects on executive functions (β=0.19; p=0.027) and that occupational complexity of paid work showed effects on memory (β=0.26; p=0.008), language (β=0.38; p<0.001), and executive functions (β=0.55; p<0.001). Conclusion: Paid work promotes cognitive reserve, contrary to household activities which seem to have a moderate impact on cognition. Differences in activity complexity not only impact people´s economic and social status and possibilities but can also determine different courses of aging and cognitive risk.

RESUMO Trabalho e atividade podem ser importantes fontes de enriquecimento cognitivo. Atividades que são mais desafiadoras quanto às funções cognitivas postas em prática se associam a menor risco de declínio cognitivo em idade avançada. Objetivo: O objetivo do presente estudo é avaliar o impacto da complexidade ocupacional e das tarefas domésticas em três domínio cognitivos (memória episódica verbal, linguagem e funções executivas) em idosos residentes na comunidade. Métodos: Foi realizada uma análise de trilha com o uso de procedimento de equações estruturais em 120 participantes, avaliados por meio de: questionário das principais atividades ocupacionais e tarefas domésticas da vida, bem como bateria de avaliação neuropsicológica para memória, linguagem e funções executivas. Resultados: A análise dos pesos de regressou mostrou que a complexidade nas tarefas domésticas apresenta efeitos moderados nas funções executivas (β=0,19; p=0,027) e que a complexidade ocupacional do trabalho remunerado teve efeitos sobre a memória (β=0,26; p=0,008), linguagem (β=0,38; p<0,001) e funções executivas (β=0,55; p<0,001). Conclusão: O trabalho remunerado promove a reserva cognitiva, em contraste com as atividades domésticas, que parecem ter impacto moderado na cognição. As diferenças na complexidade das atividades não apenas impactam o status econômico e social e as possibilidades das pessoas, mas também podem determinar diferentes cursos de envelhecimento e risco cognitivo.

Producción de inferencias explicativas en la comprensión de textos expositivos: el papel de la aptitud verbal, la memoria de trabajo y la atención selectiva / Making Explanatory Inferences in the Comprehension of Expository Texts: The Role of Verbal Ability, Working Memory, and Selective Attention / Produção de inferências explicativas na compreensão de textos expositivos: o papel da aptidão verbal, memória de trabalho e atenção seletiva

El objetivo del presente trabajo consistió en estudiar el rol de la atención selectiva, el componente retentivo y ejecutivo de información de la memoria de trabajo, y la aptitud verbal en la producción de inferencias explicativas en la comprensión de textos expositivos. Con este propósito, 171 estudiantes universitarios completaron pruebas de memoria de trabajo, atención selectiva, aptitud verbal y cuestionarios de inferencias explicativas luego de leer textos expositivos. Los resultados de las ecuaciones estructurales muestran que la producción de inferencias se explica de manera directa por la aptitud verbal y el componente ejecutivo de la memoria de trabajo. El análisis también detectó una relación de interacción de mediación entre las capacidades de producir inferencias explicativas, de atención selectiva y de almacenamiento de información verbal en memoria de trabajo. Estos componentes mostraron un efecto indirecto sobre la capacidad de inferir vía el componente ejecutivo de la memoria de trabajo. Lo anterior sugiere que la capacidad de inferir explicaciones en la comprensión está fuertemente relacionada con la aptitud verbal y la capacidad de procesar información en la memoria de trabajo, mientras que el componente retentivo y de atención selectiva muestran un impacto mediado por la memoria de trabajo.

This research aimed to study the role of selective attention, the retention and executive components of working memory, and verbal aptitude in producing explanatory inferences in the comprehension of expository texts. For this purpose, 171 undergraduates completed tests of working memory, selective attention, verbal aptitude, and explanatory inference questionnaires after reading expository texts. The results of the structural equation modeling indicated that the production of explanatory inferences is determined directly by verbal aptitude and the executive component of verbal working memory. The analysis also detected a mediation interaction effect between the abilities to produce explanatory inferences, selective attention span, and the ability to store verbal information in working memory. These components indirectly affected the ability to infer via the executive component of working memory. This suggest that the ability to make explanatory inferences in the comprehension of expository texts is strongly related to verbal aptitude and the capacity to process information in working memory, while the ability to manage selective attention and retain verbal information in shortterm memory have an impact on the ability to generate inferences mediated by working memory

O objetivo deste trabalho foi estudar o papel da atenção seletiva, do componente retentivo e executivo da memória de trabalho e da aptidão verbal na produção de inferências explicativas na compreensão de textos expositivos. Para tanto, 171 estudantes universitários responderam a testes de memória de trabalho, atenção seletiva, aptidão verbal e questionários de inferência explicativa após a leitura de textos expositivos. Os resultados das equações estruturais mostram que a produção de inferências é diretamente explicada pela aptidão verbal e pelo componente executivo da memória de trabalho. A análise também detectou uma relação de interação mediadora entre a capacidade de produzir inferências explicativas, o tempo de atenção seletiva e a capacidade de armazenar informações verbais na memória de trabalho. Esses componentes mostraram um efeito indireto na capacidade de inferir por meio do componente executivo da memória de trabalho. Isso sugere que a capacidade de inferir explicações na compreensão está fortemente relacionada à aptidão verbal e à capacidade de processar informações na memória de trabalho, enquanto o componente de atenção seletiva e seletiva apresenta impacto, mas mediado pela memória de trabalho.

Las relaciones entre prosodia y comprensión lectora en alumnos hispanohablantes: revisión sistemática y metaanálisis / Relations between prosody and reading comprehension in Spanish-speaking students: systematic review and meta-analysis

Resumen La fluidez ha sido considerada como uno de los factores relevantes que interviene en la comprensión lectora. Actualmente se incluye en la fluidez, además de la velocidad y la precisión, la prosodia como uno de los componentes que actúa de forma preponderante en la construcción del significado de la lectura. El propósito de este estudio fue realizar una revisión sistemática y un metaanálisis para determinar, por un lado, la situación de la agenda investigativa en la materia y, por el otro, mensurar la magnitud de la relación entre prosodia y comprensión lectora en alumnos hablantes nativos del español. Se realizó para ello un rastreo bibliográfico en las bases de datos Dialnet, Redalyc, SciELO, ERIC, Scopus y PubMed, sin restricciones temporales. En la revisión sistemática se incluyeron 18 estudios. Con los estudios correlacionales (n = 12) se llevó a cabo un metaanálisis multinivel, en el que se examinaron 59 coeficientes de correlación. El análisis mostró una asociación significativa entre prosodia y comprensión lectora (t(58) = 9.77, p < .001) con un efecto moderado de .46 (Z de Fisher = .49 [95 % CI = .39, .59]). Ni el nivel escolar al que asisten los alumnos (primario o secundario), ni el nivel en el que se evaluó la comprensión (oración o texto) moderaron la relación entre las variables. En suma, los resultados sostienen que las habilidades prosódicas contribuyen al procesamiento semántico de las oraciones y textos en español, más allá del nivel educativo del que se trate.

Abstract Fluency has been considered one of the relevant factors involved in reading comprehension, by providing a bridge between decoding and comprehension. At present, fluency includes, alongside rate and accuracy, prosody as one the parts which plays a preponderant role in the construction of meaning during the reading process. Prosodic reading is the use of oral language features when reading a text, such as pausing, stress and intonation, in order that the text will be read aloud with the tonal and rhythmic characteristics of speech. Furthermore, prosodic reading makes it possible to organize word sequences into syntactically cohesive units of meaning. The aim of this study was to conduct a systematic review and meta-analysis, firstly, in order to determine the situation of research articles which enquire into the relation between prosody and reading comprehension, and secondly, to measure the significance of that relation in students who are native speakers of Spanish. To that end, a bibliographic search was performed without time restrictions in the following databases: Dialnet, Redalyc, SciELO, ERIC, Scopus and PubMed. The systematic review included 18 studies. The qualitative synthesis showed four categories of articles: (1) validation studies of instruments to assess reading fluency; (2) intervention studies on different prosodic aspects and enquiries into their impact on reading comprehension; (3) comparisons of good and poor comprehenders; and (4) correlational studies. A multilevel meta-analysis was performed in the correlational studies (n = 12), examining 59 correlation coefficients. The analysis showed a significant association between reading comprehension and prosody (t(58) = 9.77, p < .001) with a moderate effect of .46 (z = .49 [95 % CI = .39, .59]). Once outlier values had been removed, no variation was found in the size of the estimated effect (r = .46). Two additional models were adjusted, including as moderating variables, respectively, the type of assessment performed on comprehension (sentence or text level) and the educational level (primary or secondary). The results obtained from these models suggest the association between comprehension and prosody is neither moderated by the type of assessment carried out (F(1, 57) = 1.51, ρ = .22), nor by the educational level (F(1, 57) = 0.10, ρ = .75). In summary, the meta-analysis showed a moderate relation between prosody and reading comprehension. These relations continued beyond the level at which the latter variable (sentence or text) was examined, and throughout the school trajectory. In other words, and in contrast to other aspects of fluency, such as accuracy and rate, prosody seems to maintain its contribution to comprehension. In sum, the findings support the claim that suprasegmental skills, both at lexical level (i. e. the skills related to the identification, stress and manipulation of stressed syllables in words) and at metrical level (the capabilities responsible for processing intonation, rhythm and pausing when reading), contribute to the semantic processing of sentences and texts in Spanish, regardless of the educational level under analysis. These results should be moderated given the limited number of studies found and the smaller amount of research carried out at secondary school level. In spite of these limitations, the relationships observed among the variables studied support the importance of prosodic reading to psychoeducational diagnosis and intervention in reading comprehension, and they provide significant background for future research.

La comprensión de narraciones orales y las diferencias individuales en niños con Trastornos del Espectro Autista / The oral narratives comprehension and individual differences in children with Autism Spectrum Disorder

Muchos niños con trastorno del espectro autista (TEA) presentan dificultad en la comprensión de narraciones orales. Investigaciones relacionadas reportan peores desempeños en inferencias emocionales respecto a otros tipos de inferencias. En este estudio participaron 15 niños con TEA entre 8 y 12 años, agrupados según nivel intelectual. Se evaluó la memoria de trabajo, la atención sostenida y el vocabulario; y medidas de comprensión como, la generación de inferencias y el recuerdo de información literal. Los resultados evidenciaron mejores desempeños en preguntas a inferencias emocionales y explicativas en los lectores con TEA sin déficit cognitivo en comparación a sus pares con déficit cognitivo. Además, no se encontraron diferencias significativas en desempeños a preguntas de información literal. Finalmente, el grupo con déficit cognitivo mostró mejor rendimiento en preguntas de inferencias explicativas respecto a otro tipo de inferencias, estos desempeños podrían vincularse con el tipo de material, narraciones orales acompañadas de ilustraciones AU

A lot of children with Autism Spectrum Disorder (ASD) present difficulty in oral narrative comprehension. Related research reports worst performance in emotional inferences than other inferences type. This study involved 15 children with ASD between 8 and 12 years, grouped according to the intellectual level. Working memory, vocabulary and sustained attention were assessed. Also, comprehension measures such as generating inferences and recalling literal information. The results evidenced better performance in emotional and explanatory inference questions in readers with ASD and without cognitive deficit than their peers with cognitive deficit. In addition, no significant differences were found in performance on literal information questions. Finally, the group with cognitive deficit showed better performance in questions of explanatory inferences compared to other types of inferences, these performances could be linked to the type of material, oral narrations accompanied by illustrations AU

El rol de las actividades del tiempo libre en la reserva cognitiva en adultos mayores / The Role of Leisure Activities in the Cognitive Reserve of Seniors / O papel das atividades de lazer na reserva cognitiva em idosos

La participación en actividades de ocio puede prevenir el deterioro cognitivo. El objetivo del presente trabajo es analizar a través de un modelo de ecuaciones estructurales, el peso relativo que tiene la participación en actividades del tiempo libre en cuatro dominios cognitivos: memoria episódica verbal, lenguaje, funciones ejecutivas y funciones atencionales en adultos mayo-res autoválidos. Para ello, se llevó a cabo un análisis de senderos, utilizando el procedimiento de ecuaciones estructurales (sem) en 167 participantes mayores (m= 72.34 años, de= 5.07 años) independientes en actividades de la vida diaria. Todos fueron evaluados con cuestionario de datos sociodemográficos, cuestionario de participación social y una batería neuro-psicológica de pruebas de uso frecuente en el ámbito clínico para memoria, lenguaje, funciones atencionales y funciones ejecutivas. Los resultados obtenidos indican que el factor de actividades muestra efectos significativos sobre el factor de funciones ejecutivas (ß = .45, p < .001, R2 = .20), también sobre el factor de memoria (ß = .38, p < .001, R2 = .14), al igual que con el factor de lenguaje (ß = .45, p < .001, R2 = .20) y el factor funciones atencionales (ß = .44, p = .03, R2 = .20). Estos resultados concuerdan con los de otros estudios que indican que las actividades de ocio podrían desempeñaron papel diferencial e importante en la construcción de la reserva cognitiva a lo largo del ciclo de vida, conformando un posible factor de protección cognitiva en el proceso de envejecimiento

Participation in cognitively demanding leisure activities can prevent cognitive decline. The objective of the present work is to analyze through a structural equation model (sem) the relative weight that partici-pation in leisure time activities has in three cognitive domains: episodic verbal memory, language execu-tive functions, and attentional functions in self-validated seniors. A path analysis was carried out using the semin 167 elderly participants (m=72.34 years, sd=5.07 years), independent in activities of daily living. All the participants were evaluated with a sociodemographic data questionnaire, a social participation questionnaire, and a neuropsychological battery of neuropsycho-logical tests frequently used in the clinical setting for memory, language, attentional functions, and executive functions. The results obtained indicate that the activities factor shows significant effects on the executive functions factor (ß=.45, p<.001, R2=.20), also on the memory factor (ß=.38, p<.001, R2=.14), as well as on the language factor (ß=.45, p<.001, R2=.20) and the attentional functions factor (ß=.44, p=.03, R2=.20). These results coincide with those of other studies that indicate that leisure activities could play a differential and important role in the construction of cognitive reserve throughout the life cycle, forming a possible cognitive protection factor in the aging process.

A participação em atividades de lazer pode prevenir o declínio cognitivo. O objetivo do presente trabalho é analisar, por meio de um modelo de equações estruturais, o peso relativo que a participação em atividades de lazer exerce em quatro domínios cognitivos: memória verbal episódica, linguagem, funções executivas e funções atencionais em idosos autovalidados. Foi realizada uma análise de trilha por meio do procedimento de equações estruturais (sem) em 167 idosos (m= 72.34 anos, dp = 5.07 anos), independentes nas atividades de vida diária. Todos os participantes foram avaliados com: questionário de dados sociodemográficos, questionário de participação social e uma bateria neurop-sicológica de testes neuropsicológicos frequentemente utilizados em âmbito clínico para: memória, linguagem, funções atencionais e funções executivas. Os resultados obtidos indicam que o fator atividade apresenta efeitos significativos sobre o fator funções executivas (ß = 0.45, p < 0.001, R2 = 0.20), também sobre o fator memória (ß = 0.38, p < 0.001, R2 = 0.14), assim como no fator linguagem (ß = 0.45, p < 0.001, R2 = 0.20) e sobre o fator funções atencionais (ß = 0.44, p < 0.03, R2 = 0.20). Estes resultados são corroborados por outros estudos que indicam que as atividades de lazer podem desempenhar um papel diferencial e importante na construção da reserva cognitiva ao longo do ciclo vital, constituindo um possível fator de proteção cognitiva no processo de envelhecimento.

Comprensión de narraciones en niños de 5 y 6 años: Efectos de la memoria de trabajo verbal y la atención sostenida / Narrative Comprehension in 5 and 6-Year-Old Children: Effects of Working Memory and Sustained Attention

Resumen Comprender un texto es una actividad cognitiva compleja que implica la construcción de una representación mental coherente en la memoria. Un proceso importante para ello es la generación de inferencias. La memoria de trabajo ha mostrado ser un factor cognitivo importante para explicar las diferencias en comprensión e inferencias, al igual que la capacidad de sostener la atención. El propósito del presente trabajo consiste en estudiar la relación entre la memoria de trabajo y la atención sostenida en la comprensión de narraciones en niños de 5 y 6 años. Para ello, se trabajó con una muestra de 100 niños, quienes escucharon tres textos narrativos y respondieron preguntas acerca de su contenido literal e inferencial, y además realizaron dos pruebas de memoria de trabajo y una de atención sostenida. Los resultados indican que los niños de 6 años muestran desempeños mejores y significativos en la comprensión de información literal y en la respuesta a preguntas de inferencia que los niños de 5 años. Además, el análisis de correlación mostró que las medidas de comprensión se hallan vinculadas a medidas de atención sostenida y a medidas de memoria de trabajo. El análisis de senderos sugiere que, en niños de 5 y 6 años, las mejoras logradas en la comprensión general como producto de la edad están mediadas, en parte, por la capacidad del niño para mantener la atención en la narración y almacenar temporalmente la información recibida en la memoria de trabajo mientras la escucha.

Abstract Text comprehension involves the construction of a coherent mental representation, which requires the person to build bridges between the new information and the background knowledge. In adults, establishing associations between information provided by the text is frequently an automatic skill, while for children it implies an important cognitive effort. This ability develops gradually over time and is connected to the generation of inferences. Working memory and the ability to sustain attention are considered two crucial processes for comprehension. The purpose of this study is to analyze the role of working memory and sustained attention in the comprehension of narratives in 5 and 6-year-old children. The study included 100 children of 5 and 6 years of age, of both sexes, that participated with the informed consent of their parents. Three oral texts were narrated to the children by a professional storyteller. For each text, six questions were asked: three of literal content and three of inferential content. Additionally, two working memory tasks were administered with one task of sustained attention. Three analyses were performed: First, a correlation analysis, to study the associations between comprehension, working memory, and sustained attention measures. Then, a comparison analysis of comprehension, working memory, and sustained attention scores between ages 5 and 6. And finally, a path analysis to study the role of age, sustained attention, and working memory on comprehension. Spearman Rho analyses in the whole sample show that literal comprehension had a significant correlation with forward digit span (Rho = .37, p < .001), backward digit span (Rho = .37, p < .001), and with the sustained attention task (Rho = -.37, p < .001). Inferences showed a significant correlation with forward digit span (Rho = .36, p < .001), backward digit span (Rho = .46, p < .001), and with the sustained attention task (Rho = -.37, p < .001). Sustained attention measures showed a significant correlation with forward digit span (Rho = -.34, p < .001) and with backward digit span (Rho = -.37, p < .001). The comparison analysis indicated significant differences between 5- and 6-year-olds in sustained attention measures (t(98) = 3.08, SEM = 5.41, p < .01), literal comprehension (t(98) = 4.05, SEM = 0.59, p < .001), and inferences (U = 750.50, z = 3.50, p < .001), but not in forward digit span (t(98) = 1.43, SEM = 0.34, p = .16) and backward digit span (U = 1043.50, z = 1.49, p = .14). A model of interrelation was proposed with age as independent variable, comprehension as dependent variable, and working memory and sustained attention as mediating variables, being comprehension, a latent factor formed by literal comprehension and inferences, and working memory another latent factor formed by forward digits and backward digits span. The path analysis showed a good fit of the data to the model (c2(5) = 1.93, p = .86; AGFI = .97, CFI = .99, TLI = .99, RMSEA = .00). The analysis showed that 6-year-olds perform better than 5-year-olds in literal and inferential information, and in sustained attention, but not in working memory. The correlation analyses, on the other hand, indicated that comprehension measures are associated to working memory and sustained attention scores and the path analysis indicated that both working memory and sustained attention play a role in comprehension. This suggests that, in 5 and 6-year-olds, age has an effect on the comprehension of general information and the ability to generate inferences, but this effect is mediated, in part, by the child's ability to sustain attention on the narration and to temporarily store the information received while listening to it.

Perfiles cognitivos de niños de nivel socioeconómico bajo con dificultades en la velocidad lectora: análisis de los resultados de una intervención / Cognitive profiles of low readers in low-SES: analysis of an intervention results

El presente trabajo busca contribuir a la comprensión de las dificultades en la adquisición de velocidad lectora en niños que crecen en contextos de pobreza. Se realizaron dos estudios: el primero se propuso comparar los perfiles cognitivos de niños con y sin dificultad en el desarrollo de la velocidad en el reconocimiento de palabras. Participaron 68 niños de 6to grado de zonas vulneradas del conurbano bonaerense: 22 niños presentaban adecuada precisión pero baja velocidad lectora y 46 niños conformaron el grupo de comparación, con niveles promedio de precisión y velocidad. A ambos grupos se les administraron pruebas de conciencia fonológica, denominación rápida, memoria verbal y escritura convencional. Exceptuando la prueba de memoria, en el resto de las pruebas el grupo con baja velocidad lectora presentó desempeños inferiores a los del grupo de comparación. El segundo estudio buscó explorar en qué medida una intervención pedagógica permitía mejorar la velocidad lectora. Para ello, los "lectores lentos" del Estudio 1 participaron de una situación pre-test-intervención para promover el desarrollo de la velocidad lectora vía formación de representaciones ortográficas-postest. Los resultados del Estudio 2 mostraron que la intervención con lecturas repetidas y aceleradas de palabras modificó significativamente el tiempo de lectura de las palabras de entrenamiento. Los datos también sugieren que el trabajo con unidades subléxicas en la intervención permitió transferir la velocidad ganada en las palabras de entrenamiento a palabras de transferencia, palabras no trabajadas en las sesiones, pero con unidades subléxicas incluidas en las palabras de entrenamiento.

Reading speed is achieved based on automatic word recognition and, together with prosody, constitutes an essential link between word recognition and text comprehension. Despite the relevance of reading speed acquisition for success at school, a high percentage of children growing up in poverty contexts face difficulties in achieving automatic word recognition. Consequently, this paper aims to contribute to the understanding of difficulties in reading speed acquisition in children growing in poverty contexts. Two studies were designed. In the first study, in order to explore the origin of difficulties in developing word reading speed, a comparison of the cognitive profiles of children from low-in-come backgrounds with and without difficulties in this ability was carried out. In a previous study, norms were obtained for accuracy and speed in a word reading test. Participants were 168 6th grade children from several educational institutions attending children growing up in poverty contexts in Buenos Aires, Argentina. In the present study, the same word reading test was administered to 96 6th grade children. Based on the norms obtained in the previous study, two groups of children were identified: a group who performed at or above the 50th percentile in reading accuracy but below the 30th percentile in reading speed and another groupper forming at or above the 50th percentile in both measures. The first group was made up of 22 children, and the second one, of 46 children. The remaining 28 children were not included in the study because they performed below the 50th percentile in reading accuracy. Additional tests measuring phonological awareness, rapid naming, verbal memory and word spelling were administered to children in both groups. Between-groups comparisons in these tasks showed that children with speed acquisition difficulties underperformed the other group in the tests tapping phonological awareness, rapid naming and spelling. These results suggest that the children in the group experiencing reading difficulties were still using the phonological route for word recognition. The second study aimed to explore whether a specifically designed educational intervention could enable children with low reading speed from the previous study to increase their reading speed. Both groups of children (with and without reading speed difficulties) were administered two additional reading tests: an experimental test comprising target words which would subsequently be included in the training study for the children with reading speed difficulties; and a reading test of additional words and pseudo words not targeted in the training study, but considered transfer items because they comprised sub lexical units that were included in the target words to be trained during the intervention. These same reading tests were re-administered as a post-test, after the reading intervention for the reading speed difficulties group. The training study aimed to promote reading speed via the acquisition of orthographic representations. The intervention involved two weekly individual sessions lasting 20 minutes each. Each child participated of a total of 15 sessions. Each session included repeated and accelerated reading of lexical units, as well as activities for promoting the analysis of sublexical units included in the target words and also present in the transfer pseudo words from the post-test. The comparison between the pre- and post-test performance of the training group showed a statistically significant increase in reading speed both of trained and transfer words, an increase that was not obtained for the comparison group. This result suggests that during the intervention children were able to develop orthographic representations of the trained lexical units, but also of the sub lexical units that were present in both the target and the transfer words. Educational implications from this study point to the importance of repeated and accelerated reading for increasing speed, a critical reading ability.

¿Qué palabras conozco?: propiedades psicométricas de una prueba de vocabulario para niños y niñas de nivel primario / Which words do I know? Psychometric properties of a vocabulary test for primary school children

El vocabulario es el conocimiento acerca de las palabras que maneja y conoce una persona. Juega un rol preponderante en el desarrollo y la ejecución de gran cantidad de habilidades cognitivas. El objetivo de este trabajo consistió en mostrar las propiedades psicométricas de un instrumento para la evaluación de la amplitud y profundidad del vocabulario (¿Qué palabras conozco? [QPC]), y su desempeño en niños y niñas de 3ro a 7mo grado de escuela primaria, de distinto nivel socioeconómico. Con este propósito se administró la prueba a 1327 niños y niñas de nivel socioeconómico medio y bajo. Las puntuaciones obtenidas mostraron evidencias muy satisfactorias de consistencia interna de los ítems y estabilidad temporal. Con respecto a las de validez, se obtuvo una correlación significativa con la tarea de vocabulario del WISC IV. Asimismo se observó que los niños y niñas de nivel socioeconómico medio presentaron un desempeño significativamente mayor que los niños y niñas de nivel socioeconómico bajo.

Vocabulary is the knowledge about words that a person uses and understands. It plays a preponderated role in the development and execution of a large number of cognitive abilities. The aim of this study was to show the psychometric properties of an instrument for the assessment of vocabulary breadth and depth (¿Qué Palabras Conozco? [QPC]), and its performance in children from 3rd to 7th grade in primary school, from different socioeconomic status. For this purpose, the test was administered to 1327 children of medium and low socioeconomic status. The scores obtained showed a very satisfactory evidence of internal consistency of the items as well as temporal stability. Regarding its validity, a significant correlation was obtained with the vocabulary task of the WISC IV. Likewise it was observed that the children from medium socioeconomic status showed a significantly higher performance than the children from low socioeconomic status.

Resolución de Problemas aritméticos en niños y niñas: incidencia de la habilidad matemática y la comprensión de texto / Arithmetic problem solving in children: the incidence of mathematical skills and text comprehension

La resolución de problemas aritméticos es una actividad cognitiva compleja, de particular dificultad para niños y niñas, que implica poder identificar los componentes relevantes, las relaciones entre ellos y poder llevar a cabo los cómputos necesarios. Distintos estudios han buscado las variables predictoras de esta capacidad, centrándose en uno de dos aspectos: la competencia matemática del niño/a o su comprensión de texto. El propósito del presente trabajo consistió en estudiar si la incidencia de uno u otro sobre la resolución de problemas en niños y niñas de 4 y 5 años se modifica por la inclusión simultánea de ambos en un modelo de ecuaciones estructurales. A su vez, existe amplia evidencia que sugiere que habilidades de dominio general, como la memoria de trabajo, influyen significativamente sobre la capacidad matemática y de comprensión de texto de los sujetos. Por este motivo, se estudió, adicionalmente, la presencia de un efecto indirecto de la memoria de trabajo verbal y visoespacial y del conocimiento previo sobre la resolución de problemas aritméticos, mediado por las otras dos habilidades. Los resultados obtenidos sugieren que, a esta edad, solo la habilidad matemática tiene un efecto directo significativo sobre la resolución de problemas, y la memoria de trabajo, tanto visual como verbal, un efecto indirecto. Asimismo, se observó que ambos componentes de la memoria de trabajo se vinculan con la capacidad matemática, pero sólo la verbal con la comprensión de texto. Por otro lado, el conocimiento previo sólo parece vincularse con la comprensión

The resolution of arithmetic word problems is a complex cognitive activity which requires the subject to identify the relevant elements, the relationships between them and to be able to carry out the necessary computations. Different studies have searched for predictive variables of this capacity, focusing on one of two aspects: the child's mathematical competence or his or her text comprehension. The purpose of the present work was to study if the incidence of one or the other on the resolution of arithmetic problems in children of 4 and 5 years of age is modified by the simultaneous inclusion of both in a structural equation model (SEM). Additionally, there is ample evidence to suggest that general domain abilities, such as working memory, significantly influence the subject's mathematical and comprehension capacity. That is why we also studied the presence of an indirect effect of verbal and visuospatial working memory, as well as the child's previous knowledge, on the resolution of arithmetic problems, mediated by the other two skills. The results suggest that, at this age, only mathematical ability has a significant direct effect on the resolution of problems, and that working memory, both visual and verbal, have an indirect effect over it. Likewise, both components of working memory are linked with mathematical ability, but only verbal working memory with text comprehension. On the other hand, prior knowledge seems to be associated with text comprehension

Desarrollo de la inteligencia emocional percibida: Estudio comparativo / Development of perceived emotional intelligence: Comparative study

La inteligencia emocional percibida está compuesta por tres factores: la atención a las emociones, la claridad emocional, y la reparación de las emociones (Salovey, Mayer, Goldman, Turvey, & Palfai, 1995). El objetivo de este trabajo es comparar y estudiar las características de la inteligencia emocional percibida en diferentes etapas de la vida. La muestra estuvo compuesta por 456 sujetos, a quienes se les administró el TMMS-21. Se hallaron diferencias en el nivel de atención y recuperación, tanto en la muestra general como en el grupo de mujeres, siendo los adultos quienes reportaron menores índices. Por otro lado, la edad resultó ser un predictor significativo del nivel de atención y reparación. Se explican las diferencias halladas a la luz del desarrollo cognitivo que afectaría la percepción que el sujeto tiene sobre sus habilidades emocionales

Perceived emotional intelligence is composed of three factors: the attention to emotions, emotional clarity and the repair of emotions (Salovey, Mayer, Goldman, Turvey y Palfai, 1995). The purpose of this work is to compare and study the characteristics of perceived emotional intelligence in different stages of life. The sample consisted of 456 subjects, who were administered the TMMS-21. Differences were found in attention and recovery levels, both in the general sample and in the group of women, with adults reporting lower rates. On the other hand, age was a significant predictor of the subject's level of attention and reparation. These differences are explained by the cognitive development that would affect the perception that the subject has about their emotional abilities.

Computerized Working Memory Battery (BIMeT-V): Studying the Relation between Working Memory, Verbal Reasoning and Reading Comprehension / Bateria Computadorizada de Memória de Trabalho (BIMeT-V): Estudo da Relação entre a Memória de Trabalho, o Raciocínio Verbal e a Compreensão de Leitura / Batería Computarizada de Memoria de Trabajo (BIMeT-V): Estudio de la relación entre la Memoria de Trabajo, el Razonamiento Verbal y la Comprensión Lectora

Abstract Working memory refers to all the systems and processes linked to the maintenance and active retention of information relevant to the performance and execution of complex cognitive tasks. Individual differences in working memory have been shown to explain differences in other cognitive abilities, such as comprehension and reasoning. The purpose of the present work was to study the relationship between verbal working memory, verbal reasoning and text comprehension, for which a verbal working memory battery was designed and validated: The verbal Computerized Working Memory Battery (Batería Informatizada de Memoria de Trabajo Verbal [BIMeT-V]). Results showed that the tests administered presented a very good reliability due to internal consistency and, in terms of validity, two latent factors saturated the tests: one of storage and one of storage and concurrent processing of verbal information. Likewise, verbal reasoning skills and the ability to comprehend expository texts are supported by working memory's concurrent storage and processing of verbal information, and to a lesser extent, or with a lesser role, the verbal information storage component.

Resumo A memória de trabalho refere-se a todos os sistemas e processos ligados à manutenção ativa e à retenção de informações relevantes para a execução de tarefas cognitivas complexas. As diferenças individuais na memória de trabalho mostraram estar ligadas com as diferenças nas habilidades, como a compreensão e raciocínio. O objetivo deste trabalho foi estudar a relação entre a memória de trabalho verbal, o raciocínio verbal e a compreensão, para o qual foi projetada e validada uma bateria de memória de trabalho verbal (Bateria de memória de trabalho verbalizada computadorizada, BIMeT-V). Os resultados mostraram que os testes administrados mostraram uma boa confiabilidade em relação a consistência interna, quanto à validade, dois fatores latentes saturavam os testes: um fator de armazenamento e outro de armazenamento e processamento simultâneo. Da mesma forma, as habilidades de raciocínio verbal e de compreensão são tarefas que são suportadas pela capacidade verbal de armazenamento e processamento simultâneo da memória de trabalho e, em menor grau, ou com um papel menos relevante, com o componente do armazenamento de informações verbais.

Resumen La memoria de trabajo se refiere a todos aquellos sistemas y procesos vinculados con el mantenimiento activo y la retención de información relevante para la ejecución de tareas cognitivas complejas. Diferencias individuales en memoria de memoria han mostrado explicar diferencias en habilidades, tales como la comprensión y el razonamiento. El propósito del presente trabajo consistió en estudiar la relación entre la memoria de trabajo verbal, el razonamiento verbal y la comprensión, para ello se diseño y validó una batería de memoria de trabajo verbal (Batería Informatizada de Memoria de Trabajo Verbal; BIMeT-V). Los resultados mostraron que las pruebas administradas mostraron una muy buena confiabilidad por consistencia interna, y en relación a la validez, dos factores latentes saturaron las pruebas: un factor del almacenamiento y otro de almacenamiento y procesamiento concurrente. Asimismo, las habilidades de razonamiento verbal y de comprensión son tareas que son soportadas por la capacidad verbal de almacenamiento y procesamiento concurrente de la memoria de trabajo, y en menor medida, o con un rol menos relevante el componente de almacenamiento de información verbal.

Patrones de correlación de fluencias semánticas y fonológicas en niños en edad escolar / Correlational Patterns in Semantic and Phonological Fluency in School Aged Children

Resumen Las tareas de fluidez verbal semántica (FVS) y fluidez verbal fonológica (FVF) son medidas sensibles para detectar y diagnosticar diversas patologías tanto en la población adulta como en la infantil. Dado que las tareas de FVS y FVF permiten detectar problemas específicos de determinadas facultades lingüísticas o cognitivas, el objetivo de este trabajo es indagar las posibles relaciones existentes entre FVS y FVF en una población de niños argentinos de nivel escolar primario de 3°, 5° y 7° grado y edades comprendidas entre los 8 y 12 años. Los 86 niños participantes respondieron a una tarea de FVS en la que se evaluaron cinco categorías (animales, partes del cuerpo, medios de transportes, ropa e instrumentos musicales) y una tarea de FVF en la que respondieron a los fonemas /f/, /a/, /s/. Se realizó un análisis de correlaciones cuyo resultado muestra que existe una asociación de mediana intensidad entre ambas tareas. Además, se llevaron a cabo un análisis factorial exploratorio y uno confirmatorio, que detectaron dos factores diferenciados: un factor verbal semántico y un factor verbal fonológico. Los resultados obtenidos muestran que los procesos fonológicos y semánticos se encuentran diferenciados desde edades tempranas, aunque por su correlación es posible concluir que ambos procesos confluyen en un mismo almacén de búsqueda en la memoria verbal.

Abstract Semantic verbal fluency tasks (SVF) and phonological verbal fluency tasks (PVF) are highly sensitive measures used to detect and diagnose different pathologies in adult and child populations. The results of numerous investigations point out differential performances between these two tasks both in adults and children. Based on this evidence, we intend to identify the possible connections between SVF and PVF in a group of Argentinian children aged 8 to 12 years old who attended to 3rd, 5th and 7th school primary levels. Participants answered to a SVF task which tested five categories (animals and body parts for living things and transports, cloth and musical instruments for inanimate objects domain) and a PVF task where the phonemes /f, a, s/ were assessed. A correlations analysis was carried out. The result showed there is a mild association between both tasks. In addition, an exploratory factor analysis and a confirmatory factor analysis were conducted. Two differential factors were detected: a semantic verbal factor and a phonological verbal factor. Our results show that phonological and semantic are different processes and function separately in early development, although due to their correlation it is possible to conclude that both processes converge in the same store in verbal memory.

Resolution of Arithmetic Problems, Processing Speed and Working Memory in Children / Resolução de Problemas Aritméticos, Velocidade de Processamento e Memória de Trabalho em Crianças / Resolución de Problemas Aritméticos, Velocidad de Procesamiento y Memoria de Trabajo en Niños Resumen

Abstract This study sought to characterize the performance of children in an arithmetic word problem test regarding choice of strategy, type of operation and age. It also analyzed possible links between the resolution of addition and subtraction problems, processing speed and working memory. Four tests were administered with 233 children of 4, 5 and 6 years of age from Buenos Aires, Argentina: (a) an arithmetic word problem test, (b) the Corsi block tapping test, (c) a digit span test, and (d) a reaction time task. Results showed a significant increase in precision when solving arithmetic word problems between ages 4 and 6. While 4-year-old children relied mainly on visual aids to solve the problems, 5 and 6-year-olds incorporated finger counting and mental calculation as efficient strategies. Arithmetic scores were associated with both verbal and visuospatial working memory scores. While only the visuospatial component predicted accuracy in the children that depended on visual aids or finger counting, both components of working memory predicted the performance of the children that primarily used mental calculation.

Resumo A presente pesquisa procurou estudar o desempenho das crianças na resolução de problemas aritméticos ao analisar à estratégia, o tipo de operação e a idade. Também se analisou possíveis relações entre a resolução de adições e subtrações, a velocidade de processamento e a memória de trabalho. Quatro testes foram administrados a 233 crianças de 4, 5 e 6 anos: (a) Um de problema aritmético, (b) A tarefa de blocos de Corsi, (c) A retenção de dígitos, (d) Uma tarefa de tempo de reação. Os resultados mostraram um aumento significativo na precisão para resolver problemas de aritmética entre 4 e 6 anos. Aos 4 anos a estratégia mais eficaz foi o uso dos recursos visuais, e aos 5 e 6 anos foram mais eficazes a contagem com os dedos e o cálculo mental. As pontuações nos problemas aritméticos associaram-se com a capacidade de memória de trabalho verbal e viso-espacial. No caso das crianças que usaram recursos visuais ou a contagem com os dedos para resolver operações, o componente da memória de trabalho que significativamente previu o seu desempenho foi o viso-espacial. Enquanto as crianças que fizeram uso do cálculo mental, os dois componentes da memória de trabalho previram o seu desempenho.

Resumen El presente estudio buscó caracterizar el desempeño de niños en problemas aritméticos teniendo en cuenta la estrategia utilizada, el tipo de operación y la edad. Se analizó, además, los posibles vínculos entre la resolución de operaciones, la velocidad de procesamiento y la memoria de trabajo. Se administraron cuatro pruebas a 233 niños de 4, 5 y 6 años de edad de Buenos Aires, Argentina: (a) problemas aritméticos, (b) bloques de Corsi, (c) span de dígitos, (d) tiempos de reacción. Se observó un aumento en la precisión en problemas aritméticos entre los 4 y los 6 años. Los niños de 4 años recurrieron principalmente a ayudas visuales, mientras que los niños de 5 y 6 años utilizaron mayormente el conteo de dedos y el cálculo mental. Los puntajes en problemas aritméticos se asociaron con los obtenidos para los componentes verbal y viso-espacial de la memoria de trabajo. En el caso de los niños que dependían de ayudas visuales o conteo con dedos para resolver las operaciones el componente que predijo de forma significativa su rendimiento fue el viso-espacial, mientras que ambos componentes de la memoria de trabajo predijeron el rendimiento de aquellos niños que utilizaban principalmente el cálculo mental.

Desarrollo de habilidades matemáticas básicas en niños de 4, 5 y 6 años / Development of basic math skills in 4-, 5- and 6-year-old children

Ciertas habilidades matemáticas básicas que se desarrollan durante la infancia son consideradas nucleares para la posterior adquisición de habilidades más complejas. Conocer su desarrollo puede facilitar la detección de dificultades en niños de forma temprana y la planificación de intervenciones tempranas. Éste estudio se propuso describir el rendimiento de niños de 4, 5 y 6 años en una serie de pruebas destinadas a evaluar estimación y discriminación de cantidades, conteo, subitización, resolución de problemas aritméticos, conocimiento de la serie numérica y comprensión de numerales arábigos. Participaron 206 niños de entre 46 a 83 meses, 112 niñas y 94 niños. Se evaluó el rendimiento de los tres grupos de edad en las tareas de habilidades matemáticas tempranas. Se observaron asociaciones significativas entre las distintas variables (p <0.05), así como diferencias en el rendimiento entre los grupos de edad (F(20, 390) = 14.93; P < .001 ; η = .44).

Certain basic mathematical skills that develop during childhood are considered core numerical abilities for the subsequent acquisition of more complex ones. Knowing their development can facilitate the early detection of difficulties in children and the design of appropriate interventions. This study aimed to describe the performance of children of 4, 5 and 6 years of age in a series of tests designed to assess estimation and discrimination of quantities, counting, subitizing, arithmetic problem solving, knowledge of the counting sequence and understanding of Arabic numerals. These were administered to 206 children, between 46 and 83 months of age, of which 112 were female and 94 male. Results showed significant associations between the different measures (p <0.05), as well as differences in performance between the age groups (F(20, 390) = 14.93, p <.001, η = .44).

Working Memory, Proces sing Speed and General Intelligence: Possible Models of Relations with Visuospatial Working Memory Using the Visuospatial Computerized Working Memory Battery (BIMeT-VE) / Memória de Trabalho, Velocidade de Processamento e Inteligência Geral: Possíveis Modelos de Relacionamento com a Memória de Trabalho Visual e Espacial Usando a Bateria Computorizada de Memória de Trabalho Visual e Espacial (BIMeT-VE) / Memoria de Trabajo, Velocidad de Procesamiento e Inteligencia General: Posibles Modelos de Relación con la Memoria de Trabajo Viso-Espacial Utilizando la Batería Informatizada de Memoria de Trabajo viso-espacial (BIMeT-VE)

Abstract Working memory is an active memory system serving the realization of complex cognitive tasks. Over the last decades' research has centered on studying the relationship of this memory system or any of its components with different cognitive functions, such as intelligence. The aim of this study is to analyze the relation between visuospatial working memory, processing speed and general intelligence, and the possible mediation role of some of these variables. To carry out this work, two studies were conducted. On Study 1 participated212 Spanish speaking college students, and a Spanish visuospatial working memory battery was designed and validated -the visuospatial Computerized Working Memory Battery (Batería Informatizada de Memoria de Trabajo Viso-Espacial; BIMeT-VE)-. On Study 2 participated 114 Spanish speaking college students, and the relationship among visuospatial working memory, processing speed and general intelligence was analyzed. The results showed that general intelligence is directly supported by the processing speed and to maintain visuospatial information for short periods of time, and indirectly by the ability to concurrently process visuospatial information.

Resumo A memória de trabalho é um sistema de memória ativo ao serviço da realização de tarefas cognitivas complexas. Nas últimas décadas as pesquisas têm-se centrado em estudar a relação entre a memória de trabalho ou seus subsistemas e outras funções cognitivas, como a inteligência. O objetivo deste estudo é analisar a relação entre a memória de trabalho visuoespacial, a velocidade de processamento e a inteligência geral, e o possível papel mediador destas variáveis. Por esta razão, foram feitos dois estudos. No primeiro desenhou-se e validou-se a Bateria Computorizada de Memória de Trabalho Visual e Espacial (BIMeT-VE) numa amostra de 212 estudantes universitários. No segundo estudo que envolveu 114 estudantes universitários analisou-se a relação entre a memória de trabalho visual e espacial, a velocidade de processamento e a inteligência geral. Os resultados mostraram que a inteligência geral está diretamente associada com a velocidade de processamento e com a habilidade de manter a informação visual e espacial a curto prazo, e indiretamente pela habilidade de processar informação visual e espacial de maneira simultânea.

Resumen La memoria de trabajo es un sistema de memoria activo al servicio de la realización de tareas cognitivas complejas. En las últimas décadas las investigaciones se han centrado sobre la relación de este sistema de memoria o alguno de sus componentes con diferentes funciones cognitivas, como la inteligencia. El objetivo de este estudio es analizar la relación entre la memoria de trabajo viso-espacial, la velocidad de procesamiento y la inteligencia general, y evaluar el posible rol mediador de alguna de estas variables. Para ello se realizaron dos estudios. En el Estudio 1 se diseñó y validó la Batería Informatizada de Memoria de Trabajo Viso-Espacial (BIMeT-VE) con 212 estudiantes universitarios hispanoparlantes. En el Estudio 2, en el que participaron 114 estudiantes universitarios hispanoparlantes se estudió la relación entre la memoria de trabajo viso-espacial, la velocidad de procesamiento y la inteligencia general. Los resultados mostraron que la inteligencia general está directamente relacionada con la velocidad de procesamiento y con la habilidad de mantener información viso-espacial por breves períodos de tiempo, e indirectamente por la habilidad de procesar concurrentemente información viso-espacial.

Inteligencia emocional y necesidad de pertenencia al grupo de pares durante la adolescencia / Emotional intelligence and need to belong during adolescence

La inteligencia emocional percibida está compuesta por la percepción sobre la atención a las emociones, la claridad con la que se perciben y la capacidad para recuperación de los estados de ánimo negativo. La necesidad de pertenencia se plantea como una necesidad humana universal y toma particular importancia durante la adolescencia. Objetivo: Analizar la relación entre la inteligencia emocional y la necesidad de pertenencia, estudiando posibles diferencias entre los sexos. Participantes: 399 adolescentes de la Ciudad Autónoma de Buenos Aires, Argentina. Materiales: Se administró la TMMS-21 y la prueba Necesidad de Pertenencia. Resultados: El factor de inteligencia emocional atención a las emociones mostró estar relacionado con la necesidad de pertenencia, en la muestra general. Esta asociación se replica solo en el caso de los varones quizás porque los niveles de atención son, en general, mayores en las mujeres. En el caso de las mujeres se encontró una asociación positiva entre recuperación y miedo al rechazo. Los resultados parecen mostrar una mayor necesidad de pertenencia en varones y un mayor miedo al rechazo en mujeres. (AU)

Perceived emotional intelligence includes a person's attention to emotions, the clarity with which they are perceived and their capacity for recovery of negative moods. Need for belonging is a universal human need and is particularly important during adolescence. Objective: To analyze the relationship between emotional intelligence and need for belonging, studying possible differences between genders. Participants: 399 adolescents in Buenos Aires City, Argentina. Materials: TMMS-21, and the Necessity of Belonging. Results: In the complete sample, attention to emotions was related to need for belonging. This association is replicated only in the case of men, perhaps because the levels of care are, in general, higher in women. In the case of women, a positive association between recovery and fear of rejection was found. The results seem to show a greater need for belonging in men and a greater fear of rejection in women.

El rol de la memoria de trabajo y la atención sostenida en la generación de inferencias explicativas / The role of working memory and sustained attention in explanatory inference generation

El propósito de este trabajo consistió en estudiar la relación entre la memoria de trabajo, la capacidad de sostener la atención y la generación de inferencias explicativas-repositivas en la comprensión de textos expositivos. Para ello, 120 alumnos universitarios leyeron dos textos expositivos del área de las ciencias naturales y completaron un cuestionario de generación de inferencia, junto con cuatro pruebas de memoria de trabajo verbal y dos pruebas que miden la capacidad de sostener la atención sobre una tarea. Los resultados indicaron que el componenente ejecutivo de la memoria de trabajo verbal tienen un efecto directo sobre la generación de inferencias, mientras la capacidad de sostener la atención y el almacenamiento de información en la memoria de trabajo verbal tienen un efecto indirecto mediado por el componente ejecutivo. Esto sugiere que las diferencias individuales en la generación de inferencias están vinculadas a las diferencias inviduales en la memoria de trabajo, y también a las diferencias individuales en la capacidad de sostener la atención.

The aim of this work was to study the relationship between working memory, sustained attention and explanatory inference generation in expository texts comprehension. To this end, 120 undergraduate students read two expository texts from natural sciences and completed an inference generation questionnaire, along with four verbal working memory tasks and two sustained attention tasks. The results showed that the executive component of verbal working memory has a direct effect on inference generation, while sustained attention and information storage in verbal working memory have an indirect effect mediated by the executive component. This supports the idea that individual differences in inference generation are related to individual differences in working memory, and also to individual differences in the ability to sustain attention.

Fluidez verbal semántica y fonológica en una muestra de niños de Argentina / Fluência semântica e fonológica em uma amostra de crianças Argentinas / Phonological and semantic verbal fluency tasks in a sample of Argentinean children

El objetivo del presente trabajo es obtener información del patrón evolutivo de desempeño en tareas de fluidez verbal para una muestra de niños argentinos de nivel primario de 3°, 5° y 7° grado. Se evaluó a los participantes con una tarea de fluidez semántica, en la que se evaluaron las categorías de animales, frutas y verduras, y partes del cuerpo para el dominio de seres vivos, y medios de transporte, instrumentos musicales y ropa para el de objetos inanimados. Asimismo fueron evaluados con una tarea de fluidez fonológica en la que se testearon los fonemas /f/, /a/ y /s/. Los datos obtenidos dan cuenta de diferencias de rendimiento entre las tareas de fluidez con un mejor desempeño en las tareas de fluidez semántica. Asimismo, en las tareas de fluidez semántica se observa un mejor rendimiento en el dominio de seres vivos. Las diferencias obtenidas en ambas tareas se identifican al comparar los grupos según escolaridad, siendo únicamente los niños de 3° grado los que, con menor cantidad de ejemplares recuperados, se disocian significativamente de los de 5° y 7° grado. Estos hallazgos son discutidos a la luz de posibles diferencias en función del desarrollo cognitivo, de las funciones ejecutivas y del sistema semántico.

No presente trabalho oferecemos dados de tarefas de fluência verbal para crianças argentinas de 3°, 5° e 7 ° ano do ensino fundamental. Os participantes foram avaliados com uma tarefa de fluência semântica, que testou as categorias de animais, frutas e legumes e partes do corpo para o domínio dos seres vivos e meios de transporte, instrumentos musicais e roupas para os objetos inanimados. As crianças também foram avaliadas com uma tarefa de fluência fonológica que testou os fonemas /f/, /a/ e /s/. Os dados obtidos apontam para diferenças de desempenho entre as tarefas e mostraram um melhor desempenho nas de fluência semântica. Além disso, nas tarefas de fluência semântica os participantes tiveram um melhor desempenho no domínio dos seres vivos. Tanto para fluência semântica quanto fonológica, as diferenças estiveram presentes quando os grupos foram comparados pelo nível de escolaridade, de modo que os alunos de 3° ano se dissociam significativamente dos 5° e 7 ° anos, produzindo menor quantidade de exemplares. Os resultados são discutidos à luz de possíveis diferenças originadas no desenvolvimento cognitivo, as funções executivas e o sistema semântico.

The aim of this work is to obtain data about the evolutionary pattern of performance in verbal fluency tasks for a sample of Argentinean primary school aged children (3rd, 5th y 7th grade) in semantic and phonological verbal fluency tasks. For the semantic fluency task, children were assessed in different categories: animals, fruits and vegetables, and body parts for living things domain, and means of transport, musical instruments and clothes for inanimate objects. For the phonological fluency assessment, children were tested with /f/, /a/and /s/phonemes. Both fluency tasks showed differences between grades, indicating the influence of education. Besides, irrespective of the grade, children performed better on the semantic fluency tasks. Results in the semantic fluency task also showed a better performance for the living things domain over the inanimate objects domain. Further analysis on the results showed that 3rd grade children have the worst performance, compared to 5th and 7th grade children. The results of our work are discussed taking in account cognitive mechanisms, executive functions and semantic memory development.

Estudio longitudinal observacional sobre los procesos de regulación afectiva y simbolización a partir de interacciones lúdicas madre-bebé y madre-niño preescolar / Longitudinal observational study of affective regulation and symbolization in mother infant interactions and mother and preschool children

En esta comunicación presentamos algunos resultados y reflexiones provenientes de un programa de investigación longitudinal (acreditado con subsidio por UBACyT y la Asociación Psicoanalítica Internacional, IPA), acerca de la relación entre la Regulación Afectiva madre-niño, la Autorregulación de los infantes, el Funcionamiento Reflexivo y los Estilos Maternos de interacción y procesos de simbolización en los primeros 5 años de vida. 48 madres y sus bebés sanos (de 6 meses de edad) fueron filmados en situaciones de juego interactivo. Cuando los mismos niños tenían 4-5 años, 21 de las madres fueron entrevistadas con la Entrevista de Desarrollo Parental en la cual se evaluó el Funcionamiento Reflexivo Parental (Slade y otros, 2005) y 17 díadas fueron filmadas en una interacción de juego libre. Se presentarán instrumentos y resultados obtenidos a partir de la codificación microanalítica del despliegue lúdico madre-niño. A los 6 meses los resultados apuntan a estudiar la regulación diádica y la autorregulación que va logrando el bebé y los posibles indicadores de retraimiento. A los 4-5 años de los niños, encontramos una relación entre el nivel simbólico observado en el niño durante las interacciones lúdicas madre-niño y el modo interactivo convergente, el nivel de funcionamiento reflexivo parental y el estilo materno interactivo facilitante.

In this communication results and reflections are presented from a longitudinal research program (funded by University of Buenos Aires and the International Psychoanalytic Association, IPA), about the relationship between Affective Mother-Child Regulation, Infant Self-Regulation, Reflective Function and Maternal Styles of interaction and processes of symbolization in the first 5 years of life. 48 mothers and their healthy babies (6 months of age) were filmed in interactive play situations. When the same children were 4-5 years old, 21 of the mothers were interviewed with the Parental Development Interview in which Parental Reflective Function was evaluated (Slade et al., 2005) and 17 dyads were filmed in a free play interaction. We will present measurements and results obtained from the micro-analytic coding of the mother-child interactive play situations. At 6 months the results showed relationships betwee dyadic affective regulation and infant self-regulation and the possible signs of withdrawal. At 4-5 years of age, we found a relationship between the convergent interactive mode, the level of parental reflective functioning, the facilitating interactive maternal style on the one hand, and the symbolic level observed in the child during mother-child play interactions.

Generación de inferencias explicativas en la comprensión de textos expositivos: el rol de la memoria de trabajo y el conocimiento previo específico / Explanation-based inferences generation in expository texts comprehension: The role of working memory and specific prior knowledge

RESUMEN El propósito de este trabajo consistió en estudiar la relación entre la memoria de trabajo, el conocimiento previo y la generación de inferencias en la comprensión de textos. Con este propósito, 167 estudiantes universitarios completaron pruebas de memoria de trabajo y cuestionarios sobre su conocimiento acerca del cambio climático y de astronomía; luego de la lectura de dos textos expositivos referidos a ambos temas, completaron un cuestionario sobre inferencias. Los resultados del análisis de correlaciones y del análisis de senderos muestran que si bien la memoria de trabajo y el conocimiento previo específico de dominio tienen una relación con la generación de inferencias explicativas-repositivas, hay una relación de interacción de mediación entre estas variables que explica el rol de ellas sobre la generación de inferencias.

ABSTRACT The aim of this research is to study the relationship between working memory, previous knowledge, and explanation-based inferences in expository text reading. To this effect, 167 undergraduates completed three working memory tasks, and two climate change and astronomy questionnaires, after reading two expository texts on these subjects. The results of the correlations and paths analyses show that, while working memory and specific previous domain knowledge are related to the generation of explanatory and reinstatement inferences, there is a mediation interaction relationship between these variables that explains their role in the generation of inferences.
