Repertório lexical de crianças de 24 e 30 meses falantes do português brasileiro: resultados preliminares / Lexical repertoire of 24 and 30-month-old children speaking Brazilian portuguese: preliminary results

RESUMO Objetivo Verificar o repertório lexical de crianças falantes do português brasileiro aos 24 e 30 meses e a associação entre a quantidade de palavras faladas e as variáveis: nível socioeconômico, escolaridade dos pais, presença de irmãos no convívio familiar, frequentar ou não escola e uso exacerbado de tablets e celulares pelas crianças. Método 30 pais de crianças com 24 meses, residentes no estado de São Paulo participaram do estudo. Por meio de plataformas de videoconferência eles foram submetidos à anamnese fonoaudiológica, entrevista com o serviço social e preencheram o "Inventário MacArthur de Desenvolvimento Comunicativo - Primeiras Palavras e Gestos", quando seus filhos tinham 24 e 30 meses. Foi aplicada estatística indutiva inferencial, quantitativa e qualitativa. Resultados A mediana das palavras emitidas foi de 283 aos 24 meses e 401 aos 30 meses, indicando aumento em torno de 118 palavras após seis meses. A criança estar frequentando ambiente escolar apresentou relação significativa com o aumento do vocabulário. Conclusão O estudo reforça o crescimento do vocabulário conforme o avanço da idade e corrobora o fato de as crianças com 24 meses já possuírem um repertório maior que 50 palavras. Aqueles que frequentam escola diariamente produzem pelo menos 70 palavras a mais dos que não frequentam.

ABSTRACT Purpose To check the lexical repertoire of Brazilian Portuguese-speaking children at 24 and 30 months of age and the association between the number of words spoken and the following variables: socioeconomic status, parents' education, presence of siblings in the family, whether or not they attend school, and excessive use of tablets and cell phones. Methods 30 parents of children aged 24 months living in the state of São Paulo participated in the study. Using videoconferencing platforms, they underwent a speech-language pathology anamnesis, an interview with social services, and then they completed the "MacArthur Communicative Development Inventory - First Words and Gestures" as soon as their children were 24 and 30 months old. Quantitative and qualitative inferential inductive statistics were applied. Results the median number of words produced was 283 at 24 months and 401 at 30 months, indicating an increase of around 118 words after six months. The child attending a school environment had a significant relationship with increased vocabulary. Conclusion The study reinforces the fact that vocabulary grows with age and corroborates the fact that children aged 24 months already have a repertoire greater than 50 words. Those who attend school every day produce at least 70 more words than those who do not.

Prediction of declarative memory profile in panic disorder patients: a machine learning-based approach

Objective: To develop a classification framework based on random forest (RF) modeling to outline the declarative memory profile of patients with panic disorder (PD) compared to a healthy control sample. Methods: We developed RF models to classify the declarative memory profile of PD patients in comparison to a healthy control sample using the Rey Auditory Verbal Learning Test (RAVLT). For this study, a total of 299 patients with PD living in the city of Rio de Janeiro (70.9% females, age 39.9 ± 7.3 years old) were recruited through clinician referrals or self/family referrals. Results: Our RF models successfully predicted declarative memory profiles in patients with PD based on RAVLT scores (lowest area under the curve [AUC] of 0.979, for classification; highest root mean squared percentage [RMSPE] of 17.2%, for regression) using relatively bias-free clinical data, such as sex, age, and body mass index (BMI). Conclusions: Our findings also suggested that BMI, used as a proxy for diet and exercises habits, plays an important role in declarative memory. Our framework can be extended and used as a prospective tool to classify and examine associations between clinical features and declarative memory in PD patients.

Methylation of BDNF gene in association with episodic memory in women.

Brain-derived neurotrophic factor (BDNF) gene regulation plays an important role in long-term memory formation, and the DNA methylation (DNAm) level of BDNF promoters has been associated with episodic memory deficits. Our aim was to explore the association between DNAm levels in BDNF promoter IV with verbal learning and memory performance in healthy women. We conducted a cross-sectional study by recruiting 53 individuals. Episodic memory was assessed by using the Rey Auditory Verbal Learning Test (RAVLT). Clinical interviews, RAVLT, and blood sample collection were assessed in all participants. DNAm was measured on DNA from whole peripheral blood using pyrosequencing. According to generalized linear model (GzLM) analyses, cytosine guanine dinucleotide (CpG) site 5 showed significant associations between learning capacity (LC, p < 0.035), that is, every 1% of DNA methylation at CpG site 5 results in a 0.068 reduction in verbal learning performance. To the best of our knowledge, the current study is the first to show that BDNF DNAm plays an important role in episodic memory.

Dietary Intake of Polyphenols Enhances Executive/Attentional Functioning and Memory with an Improvement of the Milk Lipid Profile of Postpartum Women from Argentina.

Puerperium may lead to memory and executive/attentional complaints that interfere with women's daily life. This might be prevented by dietary compounds, such as neuroprotective polyphenols. Their bioactivity depends on their effects on lipid metabolism in different tissues, such as the brain, fat, and breast. Thus, a polyphenol-related cognitive improvement may be associated with changes of lipids in human milk, which are key for infant neurodevelopment. A cross-sectional study was conducted on 75 postpartum women from Córdoba (Argentina), involving several neuropsychological tests. Diet was registered to identify polyphenol intake and food pattern adherence, with sociodemographic and other psychological variables (insomnia, stress, subjective cognitive complaints) being also studied. Triacylglycerols, cholesterol, and their oxidative forms were analyzed as milk biomarkers. Multivariate statistical methods were applied. Results confirmed that women who consumed polyphenols presented better executive/attentional performance (i.e., higher correct responses, conceptual level responses, complete categories, verbal fluency; lower attentional interferences, and perseverative errors) and word retention with lower interference. Polyphenols were positively associated with milk lipids, which were higher in women with better cognition. Furthermore, they had lower oxidized triacylglycerols. In conclusion, polyphenolic intake during postpartum may improve executive/attentional functioning, memory, and milk lipid profile.

Embodiment of an Emotional State Concurs with a Stress-Induced Reconsolidation Impairment Effect on an Auditory Verbal Word-List Memory.

Stress alters memory. Understanding how and when acute stress improves or impairs memory is a challenge. Stressors can affect memory depending on a combination of factors. Typically, mild stressors and stress hormones might promote consolidation of memory processing and impair memory retrieval. However, studies have shown that during reconsolidation, stressors may either enhance or impair recalled memory. We propose that a function of reconsolidation is to induce changes in the behavioral expression of memory. Here, we adapted the Rey Auditory Verbal Learning Test (RAVLT) to evaluate the effect of cold pressor stress (CPS) during the reconsolidation of this declarative memory. A decay in memory performance attributable to forgetting was found at the time of memory reactivation 5 d after training (day 6). Contrary to our initial predictions, the administration of CPS after memory reactivation impaired long-term memory expression (day 7), an effect dependent on the presence of a mismatch during Reactivation Session. No differences in recognition tests were found. To assess putative sources of the negative memory modulation effects induced during reconsolidation, current emotional state was evaluated immediately after Testing Session (day 7). An increase in arousal was revealed only when CPS was administered concurrently with memory reactivation-labilization. The possibility of integration during reconsolidation of independent associations of these emotive components in the trace is a critical factor in modulating neutral memories during reconsolidation by stressors.

Efficacy of the Spanish modified Story Memory Technique in Mexicans with multiple sclerosis: A pilot randomized controlled trial.

BACKGROUND: Memory impairments commonly afflict individuals with MS. While evidence-based cognitive rehabilitation treatments are available in English, the lack of such interventions in Spanish is an important barrier to care for Hispanics with MS. There is class I evidence that the modified Story Memory Technique (mSMT) improves learning in English. This intervention has been translated and adapted into Spanish. OBJECTIVE: To examine the preliminary efficacy of the Spanish mSMT to improve learning in Mexicans with MS. METHODS: Twenty individuals with relapsing-remitting MS were randomized to treatment (n = 10) or placebo control (n = 10) groups. The Spanish mSMT is a 10-session intervention that teaches imagery and context to facilitate learning. The control condition was matched to the treatment condition in treatment duration, and stimulus content and presentation. Participants completed baseline and post-treatment neuropsychological assessments. RESULTS: Individuals who received the Spanish mSMT showed significant improvements in learning and life satisfaction relative to the control group. Also observed were a near-moderate effect size on perceived memory complaints and a moderate-to-large effect size on the family's perception of the patient's competency. CONCLUSIONS: The Spanish mSMT showed preliminary efficacy in improving learning deficits in Mexicans with MS, and such improvements may extend to other domains.

Verbal Memory and Learning in Schoolchildren Exposed to Manganese in Mexico.

Manganese (Mn) is an essential nutrient for cellular function, but in high concentrations, it is neurotoxic. Environmental exposure to Mn has been associated with cognitive effects in children. This study aimed to assess the effect of environmental exposure to Mn on verbal memory and learning in schoolchildren residents from two municipalities in the state of Hidalgo, Mexico. Cross-sectional studies were conducted in 2006 and 2013 with a total of 265 schoolchildren of 7 to 11 years old. Children's Auditory Verbal Learning Test-2 (CAVLT-2) was used to assess verbal memory and learning. Mn exposure tertiles were defined according to hair manganese (MnH) levels determined by atomic absorption spectrophotometry. Linear regression models were used to estimate the association between MnH levels and CAVLT-2 scores. The models were adjusted by potential confounders. The lowest and highest exposure tertiles were defined below and above MnH levels of ≤ 0.72 and ≥ 3.96 µg/g, respectively. Mn exposure was significantly associated with an average of 5- to 9-point decrease in learning curves and summary CAVLT-2 scores in the highest tertile. This study adds to the evidence of decreased verbal memory and learning in schoolchildren environmentally exposed to manganese.

The Von Restorff effect in the Brazilian version of the Rey Auditory Verbal Learning Test in an elderly population.

The Von Restorff (isolation) effect refers to a stimulus that is more likely to be remembered amongst other stimuli in memory tasks. It has been demonstrated with different age ranges and methodologies. OBJECTIVE: To investigate: a) the presence of the isolation effect in elders tested with the new Brazilian Portuguese version of the Rey Auditory Verbal Learning Task (RAVLT) in which a word with potential emotional weight (mother) was introduced; b) whether isolation effects persist in memory disorders of different degrees of severity (Mild Cognitive Impairment [MCI]; Alzheimer's Dementia [AD]). METHODS: The RAVLT was administered to 287 consecutive volunteers. Individuals underwent medical and neuropsychological evaluation and were further sub-grouped into normal controls (n=114), MCI (n=87) and AD (n=86) patients. One-way analysis of variance (ANOVA) and Chi-squared tests were performed. Post-hoc Tukey analysis was conducted to assess significance of group differences. RESULTS: There were significant group effects on the learning curve. A W-shape - instead of the classical U-shape - was found for the serial position curve in all groups. CONCLUSION: The new Brazilian version of the RAVLT exhibited the Von Restorff effect, where this phenomenon was evident not only in older adults but also patients with MCI and AD, providing further psychometric measures for inter-group analyses.

Efeito de von Restorff (efeito de isolamento) refere-se ao estímulo que é mais facilmente lembrado em relação a outros em tarefas de memória. Tal efeito foi demonstrado em diferentes faixas etárias com diferentes metodologias. OBJETIVO: Investigar: a) presença do efeito de isolamento numa população idosa avaliada com a nova versão brasileira do Teste de Aprendizagem Auditivo-Verbal de Rey (RAVLT), em que uma palavra com potencial carga emocional ('mãe') foi introduzida; b) se o efeito de isolamento persiste em distúrbios de memória de diferentes gravidades (Comprometimento Cognitivo Leve [MCI]; Demência de Alzheimer [AD]). MÉTODOS: RAVLT foi aplicado em 287 voluntários. Indivíduos participaram de avaliações médica e neuropsicológica e foram posteriormente agrupados em controles normais (n=114), MCI (n=87) e DA (n=86). Análises de variância e testes de Chi-quadrado foram realizados. Análises post-hoc foram conduzidas para avaliar diferenças de características entre os grupos. RESULTADOS: Observaram-se efeitos significativos de grupo na curva de aprendizagem. Todos os grupos apresentaram curva de posição serial em formato W - invés do clássico formato em U. CONCLUSÃO: A nova versão brasileira do RAVLT evidenciou um efeito de von Restorff. Tal fenômeno foi visto não apenas em idosos, mas também em pacientes com MCI e AD, fornecendo medidas psicométricas adicionais para análises de diferenças intergrupais.

Marijuana use associated with worse verbal learning and delayed recall in a sample of young adults / El consumo de marihuana se asocia a una menor capacidad de aprendizaje verbal y memoria tardía en adultos jóvenes

ABSTRACT Background: There is concern about the cognitive consequences of marijuana consumption. Aim: To assess the influence of current and past marijuana use and frequency on verbal learning and memory in a sample of adults aged 21 years old. Material and Methods: Marijuana use was assessed using a clinician administered interview in 654 participants (56% females), who reported frequency of use, age of first use and whether its use led to problems in their lives. The CogState International Shopping List was administered to assess learning and memory. Results: Seventy percent reported ever using marijuana, 46% consuming during the past year and 27% during the past 30 days. The latter scored significantly lower on delayed recall. Current and frequent use were significantly associated with lower accuracy in verbal learning and memory. Conclusions: In this cohort of adults aged 21 years old, marijuana use was prevalent and related to worse verbal memory.

Ensino por múltiplos exemplares e integração de comportamentos de ouvinte e falante com unidades sintáticas substantivo-adjetivo em crianças com DENA e IC / Multiple exemplar instruction and integration of listening and speaking behaviors with substantive-adjective syntactic units in children with ANSD and CI

RESUMO Objetivo Verificar o efeito do ensino por múltiplos exemplares na aquisição e integração dos comportamentos de ouvinte e falante, com substantivos e combinações substantivo-adjetivo, em crianças com Desordem do Espectro da Neuropatia Auditiva (DENA) e implante coclear (IC). Método Participaram duas crianças com DENA que usavam IC. Foram adotados estímulos ditados e figuras que correspondiam a palavras (substantivo) e unidades sintáticas substantivo+adjetivo. O estudo foi organizado em passos de ensino que foram intercalados por avaliações dos comportamentos de ouvinte e falante, com todos os estímulos. O ensino por múltiplos exemplares apresentou tarefas de imitação oral (ecoico), reconhecimento auditivo (ouvinte) e nomeação de figuras (tato) de maneira rotativa; os substantivos foram ensinados primeiro e, em seguida, as combinações substantivo-adjetivo. Resultados No pré-teste, os participantes mostraram variabilidade e discrepância nas porcentagens de acertos de ouvinte e de falante. Todos alcançaram primeiro 100% de acertos nas tarefas de ouvinte e os desempenhos de falante ficaram próximos aos de ouvinte após o ensino. Todos estenderam a aprendizagem dos substantivos para as unidades sintáticas substantivo-adjetivo. Conclusão Crianças com DENA e IC podem aprender e integrar comportamentos de ouvinte e de falante por meio do ensino por múltiplos exemplares, de palavras a unidades sintáticas.

ABSTRACT Purpose To verify the effect of the multiple exemplar instruction at the acquisition and integration of listening and speaking behaviors, with substantives and substantive-adjective combinations, in children with Auditory Neuropathy Spectrum Disorder (ANSD) and cochlear implant (CI). Methods Participants were two children with ANSD that were users of CI. We adopted dictated stimulus and pictures that corresponded to words (substantive) and substantive-adjective syntactic units. The study was arranged in teaching steps that were intercalated with listening and speaking behaviors probes, with all stimuli. The multiple exemplar instruction presented oral imitation (echoic), auditory recognition (listening) and pictures naming (touch) tasks, on a rotating way; the substantives were taught first and, after that, the substantive-adjective combinations. Results In the pre-test, the participants showed variability and discrepancy in the correct responses percentages of listening and speaking. All achieved firstly 100% correct responses in the listening task and the speaking performances were close to listening after the teaching. All extended substantive learning to substantive-adjective syntactic units. Conclusion Children with ANSD and CI can learn and integrate listening and speaking behaviors by multiple exemplar instruction, from words to syntactic units.

Naming and verbal learning in adults with Alzheimer's disease, mild cognitive impairment and in healthy aging, with low educational levels / Nomeação e aprendizagem verbal na doença de Alzheimer, no comprometimento cognitivo leve e no envelhecimento sadio com baixa escolaridade

ABSTRACT Language assessment seems to be an effective tool to differentiate healthy and cognitively impaired aging groups. This article discusses the impact of educational level on a naming task, on a verbal learning with semantic cues task and on the MMSE in healthy aging adults at three educational levels (very low, low and high) as well as comparing two clinical groups of very low (0-3 years) and low education (4-7 years) patients with Alzheimer's disease (AD) and mild cognitive impairment (MCI) with healthy controls. The participants comprised 101 healthy controls, 17 patients with MCI and 19 with AD. Comparisons between the healthy groups showed an education effect on the MMSE, but not on naming and verbal learning. However, the clinical groups were differentiated in both the naming and verbal learning assessment. The results support the assumption that the verbal learning with semantic cues task is a valid tool to diagnose MCI and AD patients, with no influence from education.

RESUMO A linguagem tem se mostrado uma ferramenta eficiente para diferenciar grupos de idosos saudáveis dos com deficiências cognitivas. O artigo objetiva discutir o impacto do nível educacional na nomeação, na aprendizagem verbal (AV) com pistas semânticas e no MEEM no envelhecimento saudável em três níveis de escolaridade (muito baixa: 0-3 anos, baixa: 4-7 anos e alta: >8 anos) e em dois grupos clínicos de escolaridade muito baixa e baixa (Doença de Alzheimer - DA - e Comprometimento Cognitivo Leve - CCL), comparados a controles saudáveis. Participaram 101 controles, 17 CCL e 19 DA. Comparações entre grupos saudáveis demonstraram um efeito da escolaridade no MEEM, mas não nas tarefas de nomeação e de AV. Considerando as comparações entre os grupos clínicos, tanto a nomeação quanto a AV os diferenciaram. Os resultados corroboram a pressuposição de que a tarefa de AV com pistas semânticas é válida para diagnosticar CCL e DA, não sendo influenciada pela escolaridade.

Avaliação da fluência verbal em crianças com transtorno da falta de atenção com hiperatividade: um estudo comparativo / Verbal fluency evaluation in attention deficit disorder with hyperactivity children: a comparative study

OBJETIVO: comparar o desempenho de indivíduos com TDAH e grupo controle, em provas de fluência verbal, na faixa etária de 7 aos 12 anos, sem déficit cognitivo. MÉTODOS: foram avaliadas 22 crianças com TDAH e 34 do grupo controle, estudantes de escolas públicas no Estado do Rio de Janeiro. Aplicou-se uma prova de fluência verbal, subdividida em avaliação da fluência fonológica e semântica, sendo utilizada a letra F na prova fonológica e a categoria Animais na prova semântica. Os testes de fluência verbal avaliam o número de palavras produzidas espontaneamente, de forma oral, no período de um minuto. Foram criados quatro intervalos de tempo de 15 segundos procurando estabelecer relação de palavras ditas em cada intervalo por cada grupo. Os participantes foram divididos por idade para facilitar a análise dos resultados. RESULTADOS: não houve diferença relevante entre os sexos. As médias de palavras nas provas fonológica e semântica foram comparadas. Os resultados da prova fonológica foram inferiores aos da semântica, tanto no grupo com TDAH, quanto no grupo controle. Verificou-se, entretanto que os grupos com TDAH e controle apresentaram valores similares nas provas semântica e fonológica, porém com períodos de latência diferentes. CONCLUSÃO: os desempenhos de indivíduos com TDAH em provas de fluência verbal fonológica e semântica foram similares aos do grupo controle, e os resultados superiores ocorreram na prova semântica quando comparados com a prova fonológica em ambos os grupos.

PURPOSE: to compare the performances of individuals with ADHD and control group, in verbal fluency tests, from 7 to 12 years, without cognitive deficit. METHODS: 22 children with ADHD and 34 control group had been evaluated, students of a public school in the State of Rio de Janeiro. A verbal fluency test was applied, subdivided in evaluation of the phonological fluency, using the letter F and semantics, using Animal category in the semantic test. The verbal fluency tests evaluate the number of verballyproduced words, in just one minute period. Four intervals of 15 seconds had been created looking for setting up the relation of words said in each interval for each group. The participants had been divided by age to make easier the analysis of the results. RESULTS: no difference between genders was found. The average number of words in phonological and semantics tests had been compared. The performance of the phonological test had been lower than semantics in both groups. The ADHD group presented similar results to the control group in both tests, but with different latency periods. CONCLUSION: the performances of ADHD in phonological verbal fluency and semantics had been similar to the control group, and the higher results had occurred in the semantics tests in both groups.

Teste de fluência verbal no adulto e no idoso: verificação da aprendizagem verbal / Verbal fluency test in adult and elderly: verification of verbal learning

Objetivo: verificar a aprendizagem verbal em indivíduos normais submetidos ao teste de fluência verbal, considerando idade, nível de escolaridade e sexo. Métodos: indivíduos de 40 a 80 anos de idade, submetidos aos testes de fluência verbal semântica e fonológica, geradas em 1 minuto, realizado em dois momentos em 24 horas. Resultados: na análise longitudinal dos dados obtidos naprova semântica (1º dia versus 2º dia) o G1 apresentou aprendizagem verbal em todos os níveis de escolaridade, com exceção de 9 a 12 anos. No G2 observou-se significância no nível de 0 a 4 anos de escolaridade. Na prova fonológica observou-se aprendizagem verbal no G1 para todos os níveis deescolaridade, exceto de 9 a 12 anos. E no G2 foi significante no nível de 5 a 8 anos de escolaridade. Na análise transversal dos dados (G1 versus G2) não foram encontrados resultados significantes na prova semântica e na fonológica observou-se significância apenas no 2º dia nos sujeitos de 0 a4 anos de escolaridade. Na comparação entre os sexos para todas as combinações de grupo e dia na prova semântica o G1 apresentou dados significantes tanto no 1º quanto no 2º dia. Conclusão: verificou-se a ocorrência da aprendizagem verbal mais nos adultos que nos idosos em ambas asprovas. Porém na comparação entre os grupos não foram encontradas diferenças estatisticamente significantes, mas observou-se decréscimo na produção de palavras com o aumento da idade e diminuiçãodo nível de escolaridade. Na comparação entre os sexos verificou-se melhor desempenho dos homens na prova semântica.

PURPOSE: to check verbal learning in normal subjects submitted to a verbal fluency test, considering age, schooling and sex. METHODS: 200 subjects, from 40 to 80-year old, submitted to a semantic and phonologic verbal fluency test, 1 minute long, taking place twice in a 24 hours period. RESULTS: after longitudinal analysis of the data obtained from the semantic test (1st day versus 2nd day) G1 indicated verbal learning in all schooling levels, except from 9 to 12 years of schooling. For G2 the level from 0 to 4 years of schooling was significant. In phonologic test G1 indicated verbal learning in all schooling levels, except from 9 to 12 years of schooling. And for G2, the level from 5 to 8 years of schooling was significant. Transversal analysis of the data (G1 versus G2) indicated no significant semantic test results and considering the phonologic test, just the second day was significant, observing the subjects from 0 to 4 years of schooling. Comparing both genders, among all groups and combinations of days, considering the semantic test, G1 gave evidence of significant data during the first and the second day. CONCLUSION: both tests attest that verbal learning was more effective for adults than for elderly people. However, there were no significant statistical differences among all groups, except from a decrease in words creation as long as age increased and schooling decreased. By comparing both genders, men performance improved in the semantic test.

Brazilian children performance on Rey’s auditory verbal learning paradigm

The Rey Auditory Verbal Learning paradigm is worldwide used in clinical and research settings. There is consensus about its psychometric robustessness and that its various scores provide relevant information about different aspects of memory and learning. However, there are only a few studies in Brazil employing this paradigm and none of them with children. This paper describes the performance of 119 Brazilian children in a version of Rey´s paradigm. The correlations between scores showed the internal consistency of this version. Also, the pattern of results observed was very similar to that observed in foreign studies with adults and children. There was correlation between age in months and recall scores, showing that age affects the rhythm of learning. These results were discussed based on the information processing theory.

O paradigma de aprendizagem auditivo-verbal de Rey é utilizado em todo o mundo, tanto em pesquisa quanto na clínica. Há consenso sobre sua robustez psicométrica e de que seus vários escores fornecem informações relevantes sobre diferentes aspectos da memória e da aprendizagem. No entanto, existem apenas alguns poucos estudos no Brasil envolvendo este paradigma e nenhum deles com crianças. Este artigo descreve o desempenho de 119 crianças brasileiras em uma versão do paradigma de Rey. As correlações entre escores mostraram a consistência interna desta versão. Além disso, o padrão de resultados encontrado foi muito similar àquele observado em estudos estrangeiros com adultos e crianças. Verificou-se correlação entre idade em meses e os escores de evocação, mostrando que a idade afeta o ritmo de aprendizagem. Estes resultados foram discutidos a partir da teoria do processamento da informação.

Desarrollo de la habilidad oral de inglés para estudiantes de enfermería y medicina / Development of Oral Skill in English for Medical and Nursing Students

El desarrollo de las habilidades comunicativas orales es uno de los objetivos fundamentales en la enseñanza de idiomas. Esta es de vital importancia para la inserción interactiva del hombre en el mundo de hoy. Por ello hemos valorado en el mismo elementos teóricos sobre el desarrollo de la habilidad oral en la enseñanza de dicha lengua extranjera, e hicimos énfasis en la necesidad de que los profesores interioricen la importancia de planificar como parte de nuestras actividades, tareas que estimulen el desarrollo de la misma mediante la participación de los alumnos en las clases, que se conviertan en verdaderos entes activos de ella y hacedores de su propio conocimiento. Utilizamos como variables técnicas tales como: Tormenta de ideas, narración, predicción y otras vías, para un mayor uso del idioma; y fueron utilizadas en el 100% de los grupos de enfermería y medicina de ambas carreras, explorando dichos resultados a través de encuestas elaboradas con ese fin. Se concluyó que estas actividades interactivas posibilitan que el 100% de los alumnos desarrollen la habilidad oral. Por ello se analizaron una serie de posibilidades en cuanto a este tipo de actividades que se puedan desarrollar en el aula y que requieran de la activa participación de los estudiantes.

The development of oral communicative skills is one of the main objectives in teaching foreign languages. It plays a significant role for the interactive insertion of man in today's world, thus some theoretical aspects have been assessed, taking into account the development of oral skills in the teaching of the English language. Teachers need to be informed, putting emphasis on planning tasks which encourage the development of this skill through the participation of students in English classrooms, and to make them actively involved individuals and doers of their own knowledge. Technical strategies used were: brain storming ideas, narrations, predictions and others, to enhance the use of the foreign language. These strategies were used in 100% of both medical and nursery groups, exploring results obtained through surveys for this purpose. Concluding that these interactive activities make possible the development of oral skill in 100% of the students. For this, a series of possibilities to perform these kind of tasks in English clasrooms were analyzed to elicit students' talk.
