Do the benefits of learning to write a compare-contrast text transfer to other types of writing task? Analysing the effects of strategy-focused instruction / ¿Es posible transferir el aprendizaje de un texto de comparación-contraste a otro tipo de tareas? Análisis de los efectos de la instrucción estratégica

El programa de Instrucción de la Autorregulación Cognitiva (CSRI) se basa en la instrucción centrada en la estrategia e incluye tres componentes para la mejora del producto textual (enseñanza directa, modelado y práctica entre iguales). Se plantearon como objetivosanalizar si la instrucción con el programa CSRI en un género textual (texto de comparación) conducía a la transferencia espontánea en el producto textual (mejor coherencia, estructura y calidad) en un género no instruido (texto de opinión); y examinar si el orden de los componentes instruccionales presentaba algún efecto. Participaron 126 estudiantes de cuarto de educación primaria que fueron asignados a una de las dos condiciones experimentales en las que se aplicaba el programa CSRI (con diferente secuencia de los componentes instructivos), o a una condición de control en la que se seguía la enseñanza tradicional. Los resultados reflejaron que las dos secuencias de instrucción del programa CSRI mostraban beneficios en la estructura y coherencia del producto textual de los estudiantes en el posttest pero no 8 meses después. Para que los alumnos sean capaces de transferir adecuadamente lo aprendido a géneros textuales no instruidos, necesitan que los profesores les enseñen cómo hacerlo eficazmente.(AU)

Cognitive Self-Regulation Instruction (CSRI) program is a strategy-focused instruction with three instructional components for im-proving students’ writing product (direct teaching, modelling, and peer-practice). The present study aimed to explore whether the CSRI program leads to spontaneous transfer, improving the writing product (in terms of quality, structure, and text coherence) of an uninstructed genre (opinion text); and to examine whether the order in which the instructional compo-nents were implemented had an effect. A total of 126 students in their 4thyear of primary school participated in the study. They were randomly as-signed to one of two experimental conditions which received the CSRI but differed in the order the instructional components were delivered, or to a control condition which followed the traditional teaching approach. Our findings show that both CSRI sequences produced benefits in terms of greater structure and coherence of the writing product in the opinion text at post-test but not 8months after the intervention. In consequence, for students to be able to adequately transfer strategies to uninstructed text genres, they need teachers to teach them how to do it effectively.(AU)

The Impact of Children's and Parents' Perceptions of Parenting Styles on Attention, Hyperactivity, Anxiety, and Emotional Regulation.

Attention-deficit/hyperactivity disorder (ADHD) symptomatology can be studied by examining the associated neurobiological factors or by looking at the environmental factors involved, such as parenting styles. Negative parenting styles have been associated with ADHD symptoms in childhood and adolescence. The present study aimed to analyze the predictive power of two parenting style dimensions (warmth-communication and criticism-rejection) and three factors about rule-setting and compliance (inductive, strict, and indulgent styles) in the explanation of ADHD symptoms (attention and hyperactivity) and associated emotional factors (anxiety and emotional regulation) considering parents' and children's perspectives. The results indicate that from the parents' perspective, the criticism-rejection variable was the most important in explaining attention difficulties, anxiety and emotional regulation. From the children's perspective, the strict parenting style was the most important variable in explaining hyperactivity and emotional regulation. In addition, for children, warmth-communication was significant in predicting fewer emotional regulation difficulties. Our results highlight the importance of considering family dynamics when assessing ADHD in order to implement comprehensive interventions that consider parental training in positive parenting styles.

Neurodevelopmental disorders: An innovative perspective via the response to intervention model.

Neurodevelopmental disorders are a group of conditions classified together by the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders which include intellectual disability, communication disorders, autism spectrum disorder, attention-deficit/hyperactivity disorder, specific learning disorder (SLD), and motor disorders. SLD is present in many students, who exhibit significant difficulties in the acquisition of reading, written expression, and mathematics, mostly due to problems with executive functions (EF). The present study is a review of the current situation of neurodevelopmental disorders and SLD focusing on the benefits of the response to intervention model (RtI), which allows the combination of evaluation and intervention processes. It also addresses the key role of EF. The importance of adapting RtI to new possibilities such as the use of virtual reality is discussed and a theoretical framework for carrying that out is provided.

The Influence of State and Trait Anxiety on the Achievement of a Virtual Reality Continuous Performance Test in Children and Adolescents with ADHD Symptoms.

The three types of presentations of ADHD often co-occur with other disorders, anxiety being one of the most prevalent. For this reason and because there are few studies that have examined the influence of anxiety on attentional activities, this study aims to determine how internalizing difficulties (anxiety levels) can influence performance in a virtual reality continuous performance test. The study used a non-probabilistic clinical sample comprising 68 boys (66%) and 35 girls (34%) aged between 6 and 16 (M = 12.24; SD = 2.45) who had been referred to clinical services for the evaluation of ADHD symptoms. Once informed consent was given, the children were administered the STAI-C scale and a virtual reality continuous performance test by expert researchers. Hierarchical regression models showed that only state anxiety demonstrated significant explanatory power over attentional variables. These findings confirm how important it is for children to feel relaxed when they undergo psychological evaluation tests, as otherwise the individual's intervention design would be based on biased data. Similarly, the findings also suggested an effect of IQ in the interpretation of continuous performance scores.

[Empirically Supported Psychological Treatments for Children and Adolescents: State of the Art].

Empirically Supported Psychological Treatments for Children and Adolescents: State of the Art. BACKGROUND: The empirical evidence accumulated on the efficacy, effectiveness, and efficiency of psychotherapeutic treatments in children and adolescents calls for an update. The main goal of this paper objective was to carry out a selective review of empirically supported psychological treatments for a variety of common psychological disorders and problems in childhood and adolescence. METHOD: A review was carried out of the psychological treatments for different psychological disorders and problems in social-emotional or behavioral adjustment in the child-adolescent population according to the Spanish National Health System (Clinical Practice Guidelines) levels of evidence and degrees of recommendation. RESULTS: The findings suggest that psychological treatments have empirical support for addressing a wide range of psychological problems in these developmental stages. The degree of empirical support ranges from low to high depending on the phenomenon analyzed. The review suggests unequal progress in the different fields of intervention. CONCLUSIONS: From this update, psychologists will be able to make informed decisions when implementing those empirically supported treatments to address the problems that occur in childhood and adolescence.

A Case Study in Attention-Deficit/Hyperactivity Disorder: An Innovative Neurofeedback-Based Approach.

In research about attention-deficit/hyperactivity disorder (ADHD) there is growing interest in evaluating cortical activation and using neurofeedback in interventions. This paper presents a case study using monopolar electroencephalogram recording (brain mapping known as MiniQ) for subsequent use in an intervention with neurofeedback for a 10-year-old girl presenting predominantly inattentive ADHD. A total of 75 training sessions were performed, and brain wave activity was assessed before and after the intervention. The results indicated post-treatment benefits in the beta wave (related to a higher level of concentration) and in the theta/beta ratio, but not in the theta wave (related to higher levels of drowsiness and distraction). These instruments may be beneficial in the evaluation and treatment of ADHD.

Predicting Mathematics Achievement in Secondary Education: The Role of Cognitive, Motivational, and Emotional Variables.

Academic achievement in general, and in mathematics in particular, is positively associated not only with cognitive abilities, but also with emotional and motivational skills. The objective of this study was to analyze the prediction strength of cognitive, motivational, and emotional variables in mathematics achievement throughout high school, considering students' gender and age. A large sample of 2,365 Spanish students from the 4 years of high school (12-16 years old) participated in the study. Students provided information about their intellectual skills, perceived competence in mathematics, perceived utility of mathematics, intrinsic interest in learning, mathematics anxiety, and their causal attributions (for failure and for success), and of their achievement in mathematics. Data showed differences according to gender and the school grade level. The motivational and affective variables did not seem to play an important role in this relationship as predicted in the current study. The results of this study are discussed in light of previous research.

Attention, inhibitory control and early mathematical skills in preschool students / Atención, control inhibitorio y habilidades matemáticas tempranas en estudiantes de Educación Infantil

BACKGROUND: Early mathematical skills may be important indicators of school success. Executive Functions (EFs) such as attention and inhibitory control may be related to the development of early mathematical skills. METHOD: This study is aimed at understanding the relationship between two EFs (attention and inhibitory control) and low and high relational and numerical mathematical skills in preschool students (143 children between 4 and 6 years old). Participants completed the Early Numeracy Test Revised and a continuous performance test which assessed attention (omissions and response time [RT]) and inhibitory control (commissions and variability). RESULTS: Logistic Binomial Regression Analysis was carried out showing that in 4 to 6-year olds there are differences in omissions, RT and variability between the groups (low and high relational and numerical mathematical skills). However, once the effect of the age was controlled for, only RT predicted numerical mathematical skills. CONCLUSIONS: the results highlight the importance of attention in the numerical skills of preschool students, with a greater weight of response time which is better in students with higher numerical mathematics skills

ANTECEDENTES: las habilidades matemáticas tempranas pueden ser importantes indicadores del éxito escolar. Por otro lado, las Funciones Ejecutivas (FE) como la atención y el control inhibitorio se han relacionado con el desarrollo de habilidades matemáticas tempranas. MÉTODO: este estudio está dirigido a analizar la relación entre dos FEs (atención y control inhibitorio) y la baja y alta habilidad matemática relacional y numérica de 143 estudiantes de entre 4 y 6 años. Los participantes realizaron el Test de Competencia Matemática Temprana Revisado y un test de ejecución continua dirigido a evaluar la atención (omisiones y tiempo de respuesta [TR]) y el control inhibitorio (comisiones y variabilidad). RESULTADOS: el análisis de regresión logística binomial mostró que en estudiantes de entre 4 y 6 años hay diferencias en las variables omisiones, TR y variabilidad entre los grupos de baja y alta habilidad matemática relacional y numérica. Sin embargo, una vez controlada la edad, solo el TR predijo la habilidad matemática numérica. CONCLUSIONES: los resultados mostraron la importancia de la atención en las habilidades numéricas de estudiantes de Educación Infantil, con un mayor peso del TR que fue mejor en estudiantes con mejor habilidad matemática numérica

Self-Concept and Inattention or Hyperactivity-Impulsivity Symptomatology: The Role of Anxiety.

Attention-deficit/hyperactivity disorder (ADHD) has been associated with low levels of self-concept (academic, emotional, social or physical), although this association can differ in the function of the inattention or hyperactivity-impulsivity symptomatology. Furthermore, the relation between ADHD and self-concept can be mediated or moderated by the levels of anxiety. This work is aimed to examine the differential effect of inattention symptomatology and hyperactivity-impulsivity symptomatology on academic, emotional, social and physical self-concept and the mediating or moderating role of anxiety in this relationship. A total of 167 students (70.7% boys and 29.3% girls) aged between 11 and 16 participated in this study. Students' ADHD symptomatology, self-concept in four areas (academic, emotional, social and physical self-concept) and trait anxiety were measured with the State-Trait Anxiety Inventory for Children. The results indicate that trait anxiety mediates the relationship between inattention and emotional, social and physical self-concept but does not moderate this relationship. Trait anxiety does not mediate or moderate the relationship between hyperactivity-impulsivity symptoms and self-concept. When inattention symptomatology increases, academic self-concept decreases directly, but students' emotional, social and physical self-concept decreases indirectly through trait anxiety.

Is a Virtual Reality Test Able to Predict Current and Retrospective ADHD Symptoms in Adulthood and Adolescence?

Despite the persistence of attention deficit hyperactivity disorder (ADHD) into adulthood and adolescence, there are few objective, reliable instruments (based on patient performance) that have been shown to be able to predict current and retrospective ADHD symptoms. The present study aimed to explore whether a validated VR test called Nesplora Aquarium is able to predict ADHD symptoms in adults and adolescents, based on both current and retrospective self-reports. A non-clinical sample of 156 adults and adolescents (70 women and 86 men) between 16 and 54 years of age (M = 21.23, SD = 8.04) took part in the study. Virtual reality (VR) variables such as the number of correct answers, omission and commission errors, among others, were used to predict current and retrospective self-reported symptoms of ADHD using multiple regression models. Correct answers and omission errors in the VR test significantly predicted both current and retrospective ADHD symptoms. However, only the number of perseveration errors and gender were able to significantly predict retrospective ADHD symptoms. These findings suggest that inattention problems tend to remain after adolescence, while perseveration errors (which have been related to impulsive behavior) and gender differences tend to diminish.

Mathematics Competence Level: The Contribution of Non-symbolic and Spatial Magnitude Comparison Skills.

Magnitude comparison skills have been related to mathematics competence, although results in this area vary. The current study aimed to describe the performance of 75 children (aged 4-5 years) in two comparison tasks; and examine the strength of the relationship between each of the two tasks and mathematics competence level (MCL). Participants were assessed with the Early Numeracy Test which provides a global MCL score. Magnitude comparison skills were assessed with two tasks: a non-symbolic number comparison task and a spatial comparison task. Results of the Pearson correlation analysis showed a relationship between the two tasks with better performance in the spatial comparison task. Regression analysis with the stepwise method showed that only the non-symbolic number comparison task had a significant value in the prediction of the MCL pointing to the need to take these kinds of tasks into account in the first years of school.

Differential Efficacy of Neurofeedback in Children with ADHD Presentations.

Training in neurofeedback (NF) reduces the symptomatology associated with attention deficit with hyperactivity disorder (ADHD). However, ADHD differs in terms of the type of presentation, i.e., inattentive (ADHD-I), impulsive/hyperactive (ADHD-HI), or combined (ADHD-C). This study examines the efficacy of NF in ADHD presentations. Participants were 64 students (8⁻12 years old). Cortical activation, executive control, and observed symptomatology by parents were assessed. Results indicated that ADHD-C and ADHD-HI demonstrated greater improvements than ADHD-I. It was concluded that this kind of training produces an improvement and that it is necessary to explore it further in terms of the protocol used.

Influence of initial mathematical competencies on the effectiveness of a classroom-based intervention.

BACKGROUND: Students commonly struggle with mathematics and mathematical problem-solving. Therefore, it is necessary to design and implement interventions aimed at improving these essential components of learning. Furthermore, the outcomes of these interventions can vary significantly and appear to be a function of a student's initial competencies in mathematics. AIM: This study attempts to analyse the influence of initial levels of mathematics competency with respect to the benefits of a specific intervention known as the Integrated Dynamic Representation (IDR). SAMPLE: Participants were 288 students (aged 6-8 years) who were divided according to their levels of mathematics competency (low-medium-high). METHODS: Students were assigned to the two primary intervention groups, experimental group (EG; students who received the IDR intervention) and control group (CG; students who followed the traditional instructional methods). All participants completed the Test of Early Mathematics Abilities (TEMA-3) both before and after the intervention. RESULTS AND CONCLUSIONS: Although all the three competency levels of the EG improved, the progression was different for each level. Results showed that students with low competency level improved substantially more than the students with medium and/or high baseline competency level.

Comparison between two continuous performance tests for identifying ADHD: Traditional vs. virtual reality / Ejecución continua para la detección del TDAH: pruebas tradicionales frente a la realidad virtual

Background/Objective: Continuous Performance Tests (CPTs) have demonstrated validity when differentiating children with ADHD from healthy controls. However, these CPTs have limitations such as low ecological validity. New CPTs based on the use of Virtual Reality (VR) have appeared as supposedly improved methods for assessing ADHD. This study aims to compare the discriminant value of attentional variables produced by a VR CPT (Aula Nesplora) with that of variables from a traditional CPT (Test of Variables of Attention; TOVA) for identifying ADHD. Method: A total of 338 children aged between 6 and 16 years old (M = 10.84, SD = 3.01) participated in the study: 31.95% correspond to the inattentive presentation, 15.38% to the impulsive-hyperactive presentation, 22.78% to the combined presentation, and the remaining 29.88% correspond to children without ADHD. Results: Results indicated that Aula Nesplora predicts ADHD presentations better than TOVA. It also differentiates better between ADHD and non-ADHD students. Conclusions: These findings show the potential advantages of using virtual reality in ADHD assessment, as it facilitates the diagnosis of ADHD and the differentiation of its presentations in a realistic environment

Antecedentes/objetivos: Los tests de ejecución continua (Continuous Perfomance Test; CPT) han mostrado utilidad en la diferenciación de los niños con TDAH de los controles. Sin embargo, este tipo de tarea no está exenta de limitaciones como su baja validez ecológica. Para la mejora de la evaluación del Trastorno por Déficit de Atención con Hiperactividad (TDAH) surgen en los últimos años los CPTs en realidad virtual. Este estudio tiene como objetivo comparar el valor discriminativo de las variables proporcionadas por un CPT basado en la realidad virtual (Aula Nesplora) con respecto a aquellas recogidas por un CPT tradicional (Test de variables de atención; TOVA) para identificar las distintas presentaciones de TDAH. Método: Participaron un total de 338 estudiantes de entre 6 y 16 años (M = 10,84; DT = 3,01): 31,95% correspondientes a la presentación inatenta, 15,38% presentación hiperactiva-impulsiva, 22,78% presentación combinada y 29,88% controles. Resultados: Los resultados indicaron que el Aula Nesplora predice mejor que el TOVA las presentaciones de TDAH, así como a los estudiantes sin TDAH. Conclusiones: Se discuten las ventajas del uso de la realidad virtual en evaluación del TDAH, ya que facilitan el diagnóstico del trastorno y la diferenciación de sus presentaciones

Using Brain Activation (nir-HEG/Q-EEG) and Execution Measures (CPTs) in a ADHD Assessment Protocol.

Attention Deficit Hyperactivity Disorder (ADHD) is a problem that impacts academic performance and has serious consequences that result in difficulties in scholastic, social and familial contexts. One of the most common problems in the identification of this disorder relates to the apparent over diagnosis of the disorder due to the absence of global protocols for assessment. The research group of School Learning, Difficulties and Academic Performance (ADIR) from the University of Oviedo, has developed a complete protocol that suggests the existence of certain patterns of cortical activation and executive control for identifying ADHD more objectively. This protocol takes into consideration some of the hypothetical determinants of ADHD, including the relationship between activation of selected areas of the brain, and differences in performance on various aspects of executive functioning such as omissions, commissions or response times, using innovative tools of Continuous Performance Testing (based on Virtual Reality CPT and Traditional CPT) and brain activation measures (two different tools, based on Hemoencephalography- nirHEG; and Quantified Electroencephalography --Q-EEG, respectively). This model of assessment aims to provide an effective assessment of ADHD symptomatology in order to design an accurate intervention and make appropriate recommendations for parents and teachers.

Efficacy of a Continuous Performance Test Based on Virtual Reality in the Diagnosis of ADHD and Its Clinical Presentations.

OBJECTIVE: To analyze the diagnostic effectiveness of the AULA Nesplora test to discriminate the different ADHD presentations: impulsive/hyperactive (I/H), inattentive, and combined. METHOD: A total of 117 students (76.9% male and 23.1% female) between 5 and 16 years of age ( M = 11.18 years, SD = 3.10 years) participated, and were divided into three groups with ADHD according to their presentation, and a control group. RESULTS: Each of the test conditions allowed the discrimination between the I/H and combined presentations with respect to the control group, and between the I/H and inattentive presentations. However, differences among ADHD presentations were only evident when the results were separately analyzed for the visual and auditory modalities. CONCLUSION: This study showed that the indicators offered by the AULA Nesplora test (omissions, commissions, response times, and motor activity) make it possible to establish a differential diagnosis of ADHD presentations when analyzed under different contextual conditions.

Improvement of Self-regulated Learning in Mathematics through a Hypermedia Application: Differences based on Academic Performance and Previous Knowledge.

Self-regulation on behalf of the student is crucial in learning Mathematics through hypermedia applications and is an even greater challenge in these IT environments. Two aims are formulated. First, to analyze the effectiveness of a hypermedia tool in improving perceived knowledge of self-regulatory strategies and the perceived usage of the planning, executing and assessment strategy on behalf of students with low, medium and high levels of academic performance. Second, to analyze the effectiveness of the hypermedia tool in improving perceived usage of the strategy for planning, monitoring and evaluating on behalf of students with a perceived knowledge (low, medium and high). Participants were 624 students (aged 10-13), classified into a treatment group (TG; 391) and a comparative group (CG; 233). They completed a questionnaire on perceived knowledge (Perceived Knowledge of Self-Regulatory Strategies) and another one on perceived usage of the strategy for planning, performing and evaluating (Inventory of Self-regulatory Learning Processes). Univariate covariance analyses (ANCOVAs) and Student-t tests were used. ANCOVA results were not statistically significant. However, the linear contrast indicated a significant improvement in perceived knowledge of strategies among the TG with low, medium and high academic performance (p ≤ .001). Results are discussed in the light of past and future research.

Naming Speed and its effect on attentional variables and reading errors depending on the diagnosis / La velocidad de denominación y su efecto en variables atencionales y errores de lectoescritura en función del diagnóstico

While naming speed, which is usually assessed with tests like RAN / RAS, has proven to be useful in predicting certain reading errors and attentional difficulties, the variables that predict performance in the test have not been examined yet. The objective of the present study is to test the explanatory power of certain reading and attentional variables on naming speed performance depending on the diagnosis. A sample of 132 students, divided into four groups (Control, n=34; Reading difficulties, n= 22; ADHD, n=41; and ADHD+Reading Difficulties, n=35) was used. The results show: 1) without any difficulties, naming speed is explained by IQ, age and gender; 2) in presence of reading difficulties, the variables with more explanatory power are the reading errors; 3) in presence of attentional difficulties, there are certain attentional variables like those provided by TOVA, which have shown to be more significant

Si bien la velocidad de denominación, generalmente evaluada con pruebas como el RAN/RAS ha demostrado su utilidad en la predicción de ciertos errores lectores y dificultades atencionales, hasta el momento no se ha analizado que variables predicen el rendimiento en la prueba. El objetivo del presente estudio es comprobar el poder explicativo de determinadas variables lectoras y atencionales sobre la velocidad de denominación en función del diagnóstico. Se utilizó una muestra de 132 estudiantes divididos en cuatro grupos (Control, n=34; Dificultades Lectoras, n=22; TDAH, n=41; y TDAH y Dificultades Lectoras, n=35). Los resultados mostraron: 1) en ausencia de dificultades, la velocidad de denominación es explicada por el CI, la edad y el género; 2) ante dificultades lectoras, las variables con mayor poder predictivo son los errores de lectura; 3) ante dificultades atencionales, son ciertas variables atencionales como los índices proporcionados por el TOVA, las que muestran una mayor significatividad
