Además, se utilizaron las calificaciones escolares proporcionadas por docentes y datos sobre el estatus social (ES) aportados por padres/cuidadores. El diseño fue no experimental y transversal. Resultados. Los análisis de regresión jerárquica mostraron que a mayor mentalidad de crecimiento, mejor desempeño escolar, aún al controlar el efecto del ES. La relación del desempeño con las calificaciones fue más fuerte que con las pruebas estandarizadas.

Abstract Objective. The aim of the paper was to study the relation between mindset and reading comprehension and arithmetic performance of 247 students aged 9 to 12 years from two schools in Argentina. Method. Participants were asked to complete a questionnaire based on a Growth Mindset Scale, and standardized tests of reading comprehension and arithmetic calculation. In addition, school grades provided by teachers and social status data provided by parents/caregivers were used. The design was non-experimental and cross-sectional. Results. Hierarchical regression analyzes showed that the higher the growth mindset, the better the school performance, even when controlling for the effect of social status on these variables. The relation of performance with grades was stronger than with standardized tests.

Resumen Aunque las emociones básicas son consideradas universales, su significado varía según las culturas y los grupos sociales. En el marco de la construcción social de los significados, aquí se analizan y comparan las representaciones semánticas de seis emociones básicas (alegría, tristeza, enojo, miedo, sorpresa, asco) activadas por 78 niños (9 a 11 años) y 78 adultos (20 a 40 años). En base a una tarea de producción de atributos semánticos, se construyó la representación semántica asociada a cada emoción para cada rango etario. Luego, utilizando la metodología provista por el análisis de redes sociales (ARS), se analizó la calidad intrínseca y las diferencias en cantidad y tipos de atributos, estructura de las redes, densidad y nivel de entropía, y el uso de la definición por negación. Los resultados indicaron que los mapas semánticos de niños y mayores demuestran que los adultos producen mayor cantidad y diversidad de atributos que los niños, pero que ambas poblaciones comparten el núcleo del significado de los conceptos evaluados. Asimismo, muestra que la escolarización conduce a la generación de más atributos taxonómicos, que en los niños prevalecen los atributos introspectivos, que la densidad y la entropía revelan cómo los conceptos se vinculan entre sí diferencialmente en ambas poblaciones y finalmente que, frente a la dificultad para encontrar definidoras de pertenencia a una clase, los niños recurren a operaciones de contraste categorial. Entre las redes semánticas de adultos y de niños se encuentran continuidades y divergencias. En ambos grupos se encuentran separadas las emociones positivas de las negativas, lo cual es consistente con las teorías que sostienen la importancia de la valencia hedónica en la comprensión de las emociones.

Abstract Although basic emotions are considered universal, their representation, associations and meaning vary among cultures and social groups. Within the framework of the socio-constructivist theory, where the meanings develop in the social context, this paper analyzes and compares the semantic representations of six basic emotions (Joy, Sadness, Anger, Fear, Surprise and Disgust), evoked by 78 children between 9 and 11 years old and 78 adults between 20 and 40 years old. Participants had to list a series of properties/features for each concept in a Property Listing Task (PLT). With the lists produced by the participants, their frequencies and other statistical properties were calculated, and the matrix of distances between concepts was obtained from the vectors defined by each of them. Thus, using the six aforementioned emotions as stimuli, the semantic representation associated with each emotion was elaborated for each age range. Once these were obtained, an analysis was carried out to evaluate the intrinsic quality and the differences in: (1) quantity and types of features produced; (2) structure of each of the semantic networks obtained, both by means of quadratic assignment procedure (QAP) and hierarchical clustering algorithms; (3) network density (that describes the portion of the potential connections in a network that are actual connections) and entropy level (that describe the level of randomness and the amount of information encoded in a network); (4) comparative use of definition by negation; (5) qualitative analysis of the features associated with each emotional concept. To carry out the bulk of these activities and analysis, we used the tools and procedures provided by Social Network Analysis (SNA). As a result: (1) regarding the number of features, adults produced significantly more associations. A chi-square analysis found significant differences between groups in the type of features evoked, with a primacy of taxonomic for adults and introspective for children; (2) the quadratic assignment procedure found a significant level of association of .59 between the two age groups. The groupings performed at the lowest level of demand for linkage between cluster members distinguish positive emotions from negative ones; higher levels of demand begin to disaggregate the groupings: first fear and sadness are separated, then anger, then the dyad constituted by both versions of disgust. The emotion of greater commonality between children and adults is joy; (3) the density of the total network is higher in children than in adults, and the concepts of joy, disgust and sadness present a lower entropy in children than in adults; (4) Children produce considerably more definitions by the negative than adults; (5) the most similar emotion between both groups is joy and the most dissimilar is disgust. In children, disgust responds to gustatory stimuli, in adults it is used with social metaphorical value. The results obtained show the semantic representation of basic emotions in children and adults, finding both continuities (e. g. joy) and divergences (e. g. disgust) associated with the context and life experience. In both age groups, positive and negative emotions are found to be separated, which is consistent with theories on the importance of hedonic valence in the understanding of emotions. There are also differences in categorization, either more thematically or taxonomically oriented.

Resumo O presente estudo teve como objetivo desenvolver e validar um questionário acessível para avaliar as três principais funções executivas (memória de trabalho, inibição, flexibilidade cognitiva) em crianças de 9 a 12 anos: o Questionário de Funções Executivas (CUFE); e fornecer valores de referência descritivos e evidên cias sobre sua confiabilidade e validade. Para tanto, foi analisado seu funcionamento em uma amostra de 269 crianças argentinas entre 9 e 12 anos, estudantes do se gundo ciclo do ensino fundamental. A análise fatorial exploratória revelou uma estrutura de três fatores que explicou 49.08% da variância, com cargas fatoriais unidimensionais satisfatórias. Os fatores retidos apresentaram bons índices de confiabilidade e foram denominados Memória de trabalho, Inibição e Flexibilidade e controle emocional. A memória de trabalho foi associada à compreensão de leitura, ao cálculo matemático e às notas escolares de Prática de Linguagem e Matemática. As duas subescalas restantes foram associadas às notas escolares de ambas as disciplinas. As dimensões do ques tionário coincidem com os modelos teóricos atuais de funcionamento executivo. Com base nas evidências de validade e confiabilidade, o CUFE apresenta-se como um instrumento ecológico e valioso para a mensuração das funções executivas no contexto da avaliação infantil.

Resumen El presente estudio tuvo como objetivo desarrollar y validar el Cuestionario de Funciones Ejecutivas (CUFE), un cuestionario accesible para evaluar las tres principales funciones ejecutivas (memoria de trabajo, inhibición y flexibilidad cognitiva) en niños de 9 a 12 años y, así, proporcionar valores descriptivos de referencia y evidencias acerca de su confiabilidad y validez.

Abstract The present study aimed to develop and valídate an accessible questionnaire to assess the three core executive functions (working memory, inhibition, cognitive flexibility) in children aged 9-12 years: the Executive Function Questionnaire (CUFE), and to provide descriptive baseline values and evidence about its reliability and validity. The questionnaire was tested on a sample of 269 Argentinean children from 9 to 12 years old. Children attended elementary schools in Mar del Plata's city. The exploratory factorial analysis revealed a three-factor structure that explained 49.08% of the variance. The items were unidimensional and showed satisfactory factor loadings. The retained factors presented good reliability and were called working memory, inhibition and flexibility, and emotional control. Working memory was associated with reading comprehension, mathematical skills, and school grades (language practices and mathematics). Inhibition and flexibility, and emotional control were associated with school grades. The factors were consistent with current theoretical models on executive functioning. Based on the evidence obtained, the CUFE represents an ecological and valuable instrument for measuring executive functions on children.

Abstract Self-regulation -a core aspect of adaptive human behavior- is linked to developing healthy social and emotional skills, during childhood. Thus, different intervention studies on self-regulation in child population were developed worldwide. In general, these studies employ one of two basic approaches: Processes-based or school curriculum-based. In Argentina, there are research groups about the topic, but there is not a registry with information about all of them. For these reasons, this systematic review is aimed to relieve, to synthesize and to evaluate the impact of intervention programs (taking into account both approaches) which have been implemented in Argentina, in preschoolers and elementary school student. Among main results the prevalence of analysis of near short-term transfer effects, positive results in populations with and without unsatisfied needs, and difficulties in the intervention context are highlighted. We discuss about the importance of new conditions and politics for self-regulation interventions.

Resumen La autorregulación resulta fundamental para el comportamiento adaptativo, vinculándose en la infancia con el desarrollo de habilidades sociales, emocionales y cognitivas. En el mundo, se registran estudios de intervención en autorregulación en población infantil, generalmente, asumiendo uno de dos enfoques: basado en procesos o en el currículo escolar. En Argentina existen grupos de investigación sobre la temática, pero no un registro que reúna y compare sistemáticamente sus iniciativas. Consecuentemente, este trabajo se propuso mediante una revisión sistemática, relevar, sintetizar y evaluar el impacto de los programas de intervención (considerando ambos enfoques) implementados en Argentina, en niños de educación inicial y primaria. Como resultados se destacan: prevalencia del análisis de los efectos sobre la transferencia cercana a corto plazo; resultados positivos en población con y sin necesidades insatisfechas; y dificultades en el contexto de intervención. Se discute sobre la importancia de generar nuevas condiciones y políticas para la intervención en autorregulación.

Abstract Distress tolerance is defined as the ability to withstand the distress associated with aversive, negative or unpleasant emotional states. This ability to tolerate negative emotional states is a construct of outstanding interest for a broad spectrum of psychopathologies and maladaptive behaviors. One of the most frequently used measures to assess this ability is the Distress Tolerance Scale. However, there are still no studies about distress tolerance in Argentina, nor research on how the scale works in this population. Therefore, the aim of the study was to evaluate the psychometric properties of the Distress Tolerance Scale in Argentinian population. The scale was applied to a sample of 180 university students from the Mar del Plata’s National University (82.8% women and 17.2% men). The age range was from 18 to 57 years (ME: 26.8 years; SD: 7.76). Exploratory factor analysis revealed a two-factor structure that explained 47% of the variance. First factor was identified as General Distress Tolerance (sensitivity to distress); second factor was identified as Regulation (behavioral efforts to alleviate distress). General Distress Tolerance factor would represent the degree to which a person is (un)willing to keep in touch with a negative emotional experience. Regulatory factor would constitute a measure of the individual’s behavioral reactivity against to those situations. Cronbach Alpha suggested good internal consistency for the General Distress Tolerance factor (α = .87), the Regulation factor (α = .73) and the total 15-items scale (.86). Associations were also found between the General Distress Tolerance and theoretically related variables such as positive and negative affectivity, tolerance of uncertainty and anxiety and depression symptoms. Regulation factor did not show any association with the aforementioned variables. The results are similar to others reported in previous research and represent a contribution to the study of distress tolerance and its assessment in our context.

Resumen La habilidad percibida para tolerar los estados emocionales negativos es un constructo de gran interés para un gran espectro de psicopatologías. El objetivo de este estudio fue evaluar las propiedades psicométricas de la Escala de Tolerancia al Distrés en población argentina. La escala fue aplicada a una muestra de 180 estudiantes de la Universidad Nacional de Mar del Plata (82.8% mujeres, 17.2% varones; M[edad]: 26.8). El análisis factorial exploratorio reveló una estructura de dos factores que explicó el 47% de la varianza. El primer factor fue identificado como Tolerancia General al Distrés (sensibilidad al distrés); el segundo factor fue identificado como Regulación (esfuerzos conductuales para aliviar el distrés). Se encontraron asociaciones con medidas teóricamente relacionadas como afectividad, tolerancia a la incertidumbre y síntomas de depresión y ansiedad. Los hallazgos replican resultados reportados por otros investigadores y representan una contribución al estudio de la tolerancia al distrés y su evaluación en nuestro contexto.

Resumen: El objetivo de este trabajo fue analizar la relación de las estrategias de regulación emocional reevaluación cognitiva aplicada a tareas escolares para el hogar (RC-TEH) y manejo emocional aplicado a tareas escolares para el hogar (ME-TEH) sobre el desempeño académico (DA) controlando dificultades de memoria de trabajo (dif-MT) en niños que finalizaban la Educación Primaria. Se administró un cuestionario de autoinforme para evaluar la RC-TEH y el ME-TEH a 119 de niños de cuarto, quinto y sexto grado (9 a 11 años de edad) y dos cuestionarios a sus maestros para evaluar su DA y dificultades de MT. Los resultados mostraron que el ME-TEH se asoció con las dimensiones éxito, productividad académica, matemáticas y lectura del DA, incluso cuando se controlaron dif-MT. No se observaron asociaciones significativas de la RC-TEH con el DA, ni de ninguna de las estrategias sobre el control del impulso en situaciones académicas. Se espera que los resultados profundicen en el conocimiento del rol de la regulación emocional en el DA y contribuyan así al contenido de programas de promoción de la regulación emocional diseñados para contextos escolares.

Abstract: The objective of this work was to analyze the relationship between emotional regulation strategies, cognitive reappraisal applied to home school tasks (CR-HST) and emotional management applied to home school tasks (EM-HST) on academic performance (AP) controlling working memory difficulties (WM-diff) in children who finished Primary Education. A self-report questionnaire to assess CR-HST and EM-HST was administered to 119 fourth, fifth and sixth grade children (9 to 11 years old) and two questionnaires to their teachers to assess their AP and WM difficulties. The results showed that EM-HST was associated with the success, academic productivity, mathematics and reading dimensions of AP, even when WM-diff was controlled. There were no significant associations between CR-HST and AP, or any of the strategies on impulse control in academic situations. The results are expected to deepen the understanding of the role of emotional regulation in AP and thus contribute to the content of programs for promoting emotional regulation designed for school contexts.

Resumo: O objetivo deste trabalho foi analisar a relação entre as estratégias de regulação emocional de reavaliação cognitiva aplicada ao dever de casa (RC-DDC) e a gestão emocional aplicada ao dever de casa (GE-DDE) sobre o desempenho acadêmico (DA) controlando as dificuldades de memória de trabalho (dif-MT) em crianças que terminam o Ensino Fundamental. Foi administrado um questionário de auto-relato para avaliar RC-DDC e GE-DDE a 119 crianças de quarto, quinto e sexto grau (9-11 anos), e dois questionários foram administrados a seus professores para avaliar suas dificuldades de DA e MT. Os resultados mostraram que a RC-DDC estava associada ao sucesso, produtividade acadêmica, matemática e leitura da DA, mesmo quando se controla a dif-MT. Não foram observadas associações significativas para RC-DDC com DA, nem para nenhuma das estratégias de controle de impulsos em situações acadêmicas. Espera-se que os resultados aprofundem a compreensão do papel da regulação emocional na DA e assim contribuam para o conteúdo de programas que promovam a regulação emocional projetada para ambientes escolares.

Abstract Learning fractions presents large difficulties for many children and adults. This is a serious problem, because different studies have shown that fraction knowledge predicts advanced mathematics, like algebra. Adult mathematic knowledge is related to employment opportunities, participation in high-skills occupations and economic and social well-being. Therefore, since fractions represent a backbone in mathematics achievement, understanding the factors that explain fractions learning is very important. Some theories of numerical cognition propose that general cognitive factors, like attention or working memory, contribute to learning mathematics. However, recent research has shown different and contradictory results about which cognitive factors are involved in fraction learning. Identifing the cognitive factors that explain fraction knowledge could lead to early identification of children with potential math learning difficulties and the development of interventions to improve their achievement. Therefore, the aim of this article is to perform a systematic literature review to analyze the relationship among some cognitive factors and fraction knowledge. A systematic literature search could define the state of the art on this topic, identify possible sources of controversy among studies, analyze those reasons to recognize points of agreement and discrepancy among studies and direct all this information towards future research lines. A systematic search of empirical articles was done on Education Research Complete, ERIC, MEDLINE Primary Search, PsycARTICLES, and PsycINFO databases. Search was carried out on September of 2017, with keywords in Spanish and their translation into English. Search terms were “fractions” (“fracciones”) and “cognitive ability” (“habilidad cognitiva”), “cognitive processes” (“procesos cognitivos”), “working memory” (“memoria de trabajo”), “attention” (“atención”), “intelligence” (“inteligencia”), “speed of processing” (“velocidad de procesamiento”), “inhibition” (“inhibición”) and “language” (“lenguaje”). Articles inclusion criteria were: (a) empirical studies, (b) with scholar age samples (6-18 years old), (c) published on peer review journals, (d) written in spanish or english. Thirteen publications were selected. They agree about attention predicting conceptual and procedural knowledge of fractions between fourth and sixth grade, (b) language and fluid intelligence explains conceptual knowledge of fractions in the initial stage of its systematic teaching, (c) central executive predicts fractions concepts in advanced levels of fraction instruction but not in the initial stages of learning, (d) central executive and fluid reasoning does not predict procedural fraction knowledge when other cognitive factors and mathematical abilities, like attention or whole number calculation skills, are included in the explanation models. In broad terms, these results are in line with some theoretical models of numerical cognition and suggested that cognitive processes and abilities are important to learn fractions. There are some practical implications to these results. Fraction learning could be improved by using pedagogical strategies and didactic materials which maximize cognitive performance. For example, employing novelty and ludic materials for teaching fractions could enable students to focus, maintain attention and improve their learning. Also, short instructions with low linguistic complexity would help students with attention, working memory or language difficulties to afford fractions activities and achieve a meaningful learning. On the other hand, working memory load to perform complex fraction activities would be reduced if basic fraction concept and procedures are consolidated in long term memory. Therefore, before advancing to more complex fractions activities in higher grades, the teacher should verify that the basic notions of fractions have been learnt and memorized by students. To develop theoretical cognitive models of mathematics learning, future research might analyze if cognitive factors contribute to fractions knowledge mainly through direct or indirect effects (that is, via their effects on others areas of math knowledge which affect fraction learning). On the other hand, the tasks used to measure cognitive factors are not always pure, that is, different cognitive operations are involved in their execution. Future studies might work with latent variables that allow the identification of the share variance between cognitive task, and consequently, the main cognitive factors involved in fractions learning.

Resumen El objetivo de este trabajo es realizar una revisión de la literatura que permita comprender la relación del conocimiento de las fracciones con los factores cognitivos en estudiantes de escolaridad primaria y secundaria. Se realizó una búsqueda de artículos empíricos en las bases de datos Education Research Complete, ERIC, MEDLINE, Primary Search, PsycARTICLES y PsycINFO. Los criterios de inclusión fueron: (a) trabajos empíricos, (b) efectuados con niños de escolaridad primaria o secundaria (de 6 a 18 años de edad), (c) publicados en revistas científicas con referato y (d) redactados en español o inglés. Las investigaciones seleccionadas coinciden respecto de que: (a) la atención predice el conocimiento conceptual y procedimental de las fracciones, (b) el lenguaje y la inteligencia fluida explican el conocimiento conceptual de las fracciones en la etapa inicial de su enseñanza sistemática y (c) el ejecutivo central contribuye a la predicción del conocimiento conceptual de las fracciones en años avanzados de la escolaridad. Se discuten las implicaciones teóricas y prácticas de estos resultados y se señalan posibles líneas de investigaciones futuras.

Background: in recent years it has been proposed that cognitive strategies of emotional regulation (CSER) would have predictive capacity on different indicators of well-being, since some of them would be effective to directly increase the experience of positive emotions and lessen the negative ones. Objective: this investigation aimed to analyze the explanatory contribution of using CSER to influence the levels of subjective well-being (SWB) and psychological well-being (PWB) in university students, because this population is characterized by its particular vulnerability due to the demands of academic life. Method: eighty-four (84) university students of the psychology program from the National University of Mar del Plata were evaluated, whose average age was 23 years old. Correlation and multiple linear regression analyses were conducted to assess the data. Results: adaptive CSER (CSER- AD) were found to be positively associated with both types of well-being, while non-adaptive CSER (CSER-NA) did so in the opposite direction. Conclusions: this study shows the explanatory contribution of the differential use of CSER in university students’ well-being levels. The results could contribute to designing health promotion and prevention programs in this population, given that feelings of well-being influence the coping skills for facing the academic demands.

Antecedentes: en los últimos años se ha propuesto que las estrategias cognitivas de regulación emocional (ECRE) tendrían capacidad predictiva sobre distintos indicadores de bienestar, dado que algunas de ellas serían eficientes para elevar directamente la experiencia de emociones positivas y disminuir la experiencia de emociones negativas. Objetivo: el objetivo de esta investigación fue analizar la contribución explicativa del uso de las ECRE para los niveles de bienestar subjetivo (BS) y de bienestar psicológico (BP) en estudiantes universitarios, debido a que esta población se caracteriza por una vulnerabilidad particular producto de las exigencias de la vida académica. Método: se evaluaron 84 estudiantes universitarios de la Licenciatura en Psicología de la Universidad Nacional de Mar del Plata, con una edad promedio de 23 años. Se realizaron análisis de correlación y de regresión lineal múltiple para analizar los datos. Resultados: se observó que las ECRE adaptativas (ECRE-AD) se asociaron positivamente con ambos tipos de bienestar, en tanto las ECRE no adaptativas (ECRE-NA) lo hicieron en sentido opuesto. Conclusiones: este estudio muestra la contribución explicativa del uso diferencial de las ECRE con los niveles de bienestar de estudiantes universitarios. Los resultados podrían ser un aporte al diseño de programas de promoción y prevención de la salud en esta población, dado que los sentimientos de bienestar influyen en las formas de afrontar las demandas académicas.

Resumen Diferentes estudios indicaron que el aprendizaje de la matemática se asocia con los recursos cognitivos que dispone el estudiantado para afrontar su construcción. Sin embargo, la relación específica de procesos y habilidades cognitivas con la capacidad de cálculo de operaciones de división ha sido escasamente analizada. El objetivo de este artículo empírico es analizar la relación de la capacidad de cálculo de operaciones de división con el rendimiento en memoria de trabajo, inhibición e inteligencia fluida. La muestra fue seleccionada por disponibilidad y estuvo integrada por 135 estudiantes de 4º año del sistema educativo argentino (participantes de 9 y 10 años de edad). Los mismos fueron evaluados dentro de los establecimientos educativos a lo que asistían, durante el horario habitual de clases, a través de diferentes tareas que permitían la medición de tales variables. Los resultados indicaron que los estudiantes con distinto nivel de desempeño en división diferían entre sí en todas las variables cognitivas estudiadas (a excepción de la inhibición). Este hallazgo muestra que la inteligencia fluida y memoria de trabajo se relacionan con el conocimiento de la división en estudiantes de 4º año de la escolaridad primaria. Asimismo, sugiere que el aprendizaje de esta operación podría facilitarse al considerar las diferencias individuales en estos factores cognitivos durante el diseño y selección de los materiales didácticos y estrategias pedagógicas a utilizar para su enseñanza.

Abstract Different studies have shown a relationship between mathematics learning and cognitive factors; however, the specific link between division and cognitive abilities has been less studied. Previous research has shown that division ability during elementary school years is one of the most important predictors’ factors of general mathematic achievement in high school. Therefore, recognizing the cognitive factors related to division is important to improve mathematic learning in high school. The aim of this study was analyzed the relationship among division, working memory, inhibition and fluid intelligence. The sample was choose by the availability of the participants and it was integrated by 135 4th grade students (ages: 9- 10) from the Argentine educational system. They were assessed inside their school during regular classes schedule using different task. The results indicate that the students with different level in the division achievement diverge between them in the cognitive variables studied (inhibition was an exception).This conclusion showed that students’ differences in division achievement were related to working memory and fluid intelligence. Those findings show a relation between intelligence and working memory and suggest that division learning could be improved by considering individual differences on those cognitive factors.

Working memory (WM) is a strong predictor of academic performance, due to its impact in reading comprehension, arithmetic's competence and the regulated behaviors required for school learning. Thus, knowing about WM operation in school-aged children and teachers' perception on their students WM is of great value and interest. This is why in the present work we assess whether teachers' reports about their students' WM (indirect measure) is associated with their performance in WM tasks (direct measure), and also to assess whether the difficulties perceived by the teachers correspond to the presence of students' general behavioral issues. For that, we administered computerized verbal WM tasks to school-aged children, in which they had to recall a number of digits (control condition) while saying out loud the color of the items (interference condition), and computerized visual-spatial WM tasks, in which they had to recall the locations of a series of stimuli (control condition) while indicating the color of the stimuli in a color palette (interference condition). We also administered two scales to their teachers: one of them asks about WM specifically (Working Memory Rating Scale) and is composed of 20 short descriptions of behavior problems that allow discriminating between children with poor and average WM skills. The teacher rates how typical a behavior is in each child, in a scale that goes from Not typical at all (0) to Very typical (3). The other asks about diverse behavioral problems (Guide of Behavioral Observation) and is composed of the following subscales: Physical and Verbal Aggression, Negativism, Transgression, Impulsivity, Hyperactivity, Attention Deficit and Acceptance. The teacher must choose the option that best describes the behavior in the child in terms of frequency (Never, Sometimesor Often). Our results show significant associations between children performance in the verbal WM task (direct measure) and WM failures' indicators (indirect measures), which can be explained by the fact that the verbal component is more clearly reflected in the behaviors explored in the Working Memory Rating Scale (e.g., loses his place in complicated activities, requires regular repetition of instructions, depends on neighbor to remind them of the current task). We also wanted to look out if there were associations between the WM skills reported by the teachers and the general behavior problems also reported by them, and we found associations between the reported WM difficulties and attention disorders, hyperactivity and self-aggression. This is consistent with the claim that WM and attention deficit in non clinical population are closely related. With respect to hyperactivity, its relation with WM is not as clear and has not been so frequently reported. With respect to self-aggression, its relation with WM difficulties can be attributed to these children's in ability to exercise control over the environment, which leads to frustration and low levels of motivation and self-esteem. Lastly, we found associations between children's performance in the computerized WM tasks and the presence of behavioral problems informed by the teachers. Specifically, proper performance in verbal WM tasks associates with less attention difficulties, where as proper performance in visual-spatial WM tasks associates with being accepted by the group. This last association could be attributed to the fact that many group games require several abilities that involve visual-spatial WM, such as the ability to orientate in space and recall different locations. To conclude, we consider that this work constitutes a contribution because, in the first place, there are no WM observation scales for teachers' use available in our environment, and, in the second place, it addresses the need for teachers to acknowledge WM difficulties and consequently be trained for the implementation of effective strategies to im prove WM skills in the classroom.

La memoria de trabajo (MT) es un fuerte predictor del desempeño académico por su impacto en la comprensión lectora, la competencia aritmética y los comportamientos necesarios para el aprendizaje escolar. De modo que saber cómo opera la MT en niños de edad escolar y conocer la percepción que los docentes tienen sobre la MT de sus estudiantes es de gran interés. Por eso, los objetivos del trabajo que se informa fueron evaluar si las observaciones de los docentes sobre las dificultades en la MT de sus alumnos (medidas indirectas) se relacionan con el rendimiento de estos alumnos en pruebas de ejecución de MT (medidas directas) y analizar si estas dificultades percibidas por los docentes se corresponden con la presencia de problemas comportamentales de diversos tipos. Para esto se les administraron a niños de edad escolar pruebas de MT verbal y MT viso-espacial informatizadas, y a sus docentes dos cuestionarios, la Escala Observacional de Memoria de Trabajo -WMRS- y la Guía de Observación Comportamental -GOC-. Los resultados obtenidos muestran asociaciones significativas entre indicadores de fallos en MT y la performance de los niños en la tarea de MT verbal, debidas probablemente a que en los comportamientos explorados en la WMRS el componente verbal está más claramente reflejado (e.g., requiere repeticiones de instrucciones). También se encontró que estos fallos se relacionan con problemas comportamentales reportados por los docentes, como ser dificultades atencionales, hiperactividad y autoagresión. Se considera al estudio realizado como una contribución porque no hay escalas observacionales de MT para uso docente, disponibles en nuestro medio.

ABSTRACT: The aim of the study was to analyze the explanatory power of the components of working memory (WM) with respect to reading comprehension (RC) and mathematical computation (MC) skills in school-age children. The sample was obtained through a purposive non probability procedure and consisted of 84 Argentinean children of both sexes, aged 9-11 years. WM was assessed with the computer-based Tareas de Autorregulación Cognitiva [Cognitive Self-Regulation Tasks] (TAC) battery, RC with the screening task from the Leer para Comprender [Reading to Understand] Test, and MC with the Mathematical Computation sub-test from the WRAT-3. Multiple linear regression analyses were performed and the unique percentage of variance explained by each component was calculated. Results showed that verbal storage and the executive component explained RC, while both verbal and visuo-spatial storage and the executive component explained MC. These results are important for gaining in-depth knowledge about the role of WM in RC and MC in local children.

RESUMEN: El objetivo del estudio fue analizar la capacidad explicativa de los componentes de la memoria de trabajo (MT) en las habilidades académicas de comprensión lectora (CL) y cálculo matemático (CM) en niños de edad escolar. La muestra estuvo compuesta por 84 niños argentinos de ambos sexos, de 9 a 11 años de edad, seleccionados mediante un muestreo no probabilístico intencional. La MT se evaluó mediante la batería informatizada de Tareas de Autorregulación Cognitiva (TAC), la CL, con la prueba de screening del Test Leer para Comprender y el CM, con el sub-test Cálculo Matemático del WRAT-3. Se realizaron análisis de regresión lineal múltiple y se calculó el porcentaje único de varianza explicada por cada componente. Los resultados mostraron que los componentes de almacenamiento verbal y ejecutivo explicaron la CL, mientras que el almacenamiento verbal, visoespacial y el componente ejecutivo explicaron el CM. Estos resultados son de interés para profundizar en el conocimiento del rol de la MT en la CL y el CM en niños del medio local.

Resumen La habilidad de reevaluación cognitiva (HRC) es una estrategia de regulación emocional que implica resignificar un evento para cambiar su efecto emocional. En los niños, esta habilidad permite disminuir experiencias emocionales negativas y se ha mostrado como un factor de protección frente a la ansiedad y depresión. Sin embargo, aún resta conocer los factores que contribuyen a explicar las diferencias individuales en esta habilidad. Uno de estos factores son las funciones ejecutivas, ya que contribuyen al control cognitivo de la emoción. El objetivo de este trabajo fue analizar el rol de las funciones ejecutivas en la HRC. Se evaluaron 100 niños de 9 a 12 años (M = 10.49; DS = 1.10) en memoria de trabajo, flexibilidad cognitiva espontánea, inhibición y HRC mediante la tarea de amplitud oral (Batería AWMA), prueba de fluidez verbal semántica (Batería ENI) y la tarea de identificación de reevaluaciones cognitivas (TIRC) elaborada para este estudio. Los datos se analizaron mediante regresión lineal múltiple. Los resultados mostraron que las funciones ejecutivas predecían la HRC, es decir, los niños que tuvieron mejor desempeño en funcionamiento ejecutivo mostraron mayor HRC. Se espera que estos resultados permitan profundizar el conocimiento de los procesos implicados en el control cognitivo de la emoción.

Abstract The Cognitive Reappraisal Ability (CRA) is an emotional regulation strategy that involves giving a new meaning to an event in order to change the emotional response. In children, this skill helps reduce negative emotional experiences and has proven to be a protective factor against anxiety and depression. However, there's still the need to understand the factors that may influence on the individual differences in the CRA. One of these factors is executive functions, since they contribute to the cognitive control of emotion. The aim of this study was to analyze the role of executive functions in the CRA. We evaluated 100 children whose ages ranged from 9 to 12 years (M=10,49; DS=1,10) on their working memory capacity, spontaneous cognitive flexibility, inhibition and CRA using a Verbal Span Task (AWMA) , Verbal Fluency Task (ENI Battery) and a Cognitive Reappraisal Task CRT, which was designed for this research. Data set was analyzed by linear regression analysis. The results showed executive functions preceded CRA, i.e. children who performed better in executive functioning showed higher CRA. It is expected that these results permit a deeper understanding of the processes involved in cognitive control of emotion.

El objetivo de este trabajo fue analizar las relaciones entre el conocimiento conceptual y el procedimental de las fracciones durante su aprendizaje. Para esto se efectuó una búsqueda bibliográfica en las bases de datos ERIC, PsycInfo, Scielo y Redalyc, con los siguientes términos en español y sus equivalentes en inglés: fracciones (fractions), conocimiento conceptual (conceptual knowledge), conocimiento procedimental (procedural knowledge) y niños (children), combinados de diferente forma con el operador booleano AND (Y). Los resultados de esta búsqueda permitieron hallar quince artículos empíricos que pueden clasificarse en cuatro grupos de investigaciones: las que indican una relación bidireccional, las que sugieren una relación unidireccional, las que muestran cierta independencia o restricciones en su vinculación y, por último, las que señalan que las relaciones varían según los sujetos. Esta falta de acuerdo podría explicarse por ciertas diferencias metodológicas de los estudios, por ejemplo, diferencias en el grado de consolidación del conocimiento de las fracciones de los participantes, el sentido conceptual o la habilidad procedimental estudiada, el tipo de enseñanza matemática recibida, etc. Por ello se sugiere que, para profundizar la comprensión de las relaciones entre el conocimiento conceptual y procedimental de las fracciones, estos aspectos metodológicos deben ser controlados.

The aim of this study was to analyze the relationship between conceptual knowledge and procedural knowledge of fractions during learning. For this propose, a literature search was conducted in the databases of ERIC, PsycINFO, Scielo and Redalyc, using the following terms in English and their equivalent word in Spanish: Fractions (fracciones), conceptual knowledge (conocimiento conceptual), procedural knowledge (conocimiento procedimental) and children (niños). The terms were combined in different ways using the Boolean operator AND. The results of this search produced fifteen empirical articles that can be classified into four research groups: those that indicate a bidirectional relationship, those that suggest unidirectional relationship, those that showed some independence or restrictions on their relationship and those stating that relationships vary according to subjects. This lack of agreement could be explained by some methodological differences among studies, for example, differences in the consolidation degree of fraction knowledge of the participants, the conceptual sense or procedural ability studied, the type of mathematical education received, etc. Therefore, so as to deepen the understanding of the relationship between conceptual and procedural knowledge of fractions, we suggest that such methodological aspects should be controlled.

El objetivo de este trabajo fue proponer y analizar dos modelos de asociaciones para explicar las relaciones entre los rasgos extraversión y neuroticismo; las estrategias de regulación emocional, reevaluación cognitiva (RC) y supresión de la expresión emocional (SEE), y la ansiedad y depresión en niños de 9 a 12 años de edad. Se evaluaron 230 niños de ambos géneros de dichas edades en las variables mencionadas y se contrastaron los modelos mediante análisis de senderos (path analysis). Los resultados mostraron que la RC presentó un efecto mediador total en la relación de la extraversión con la ansiedad, algo que no se observó para la depresión. La SEE presentó un efecto mediador parcial en la relación del neuroticismo con la ansiedad y con la depresión Estos resultados poseen valor para ampliar el conocimiento disponible respecto del efecto de estos rasgos en la sintomatología clínica, lo que resulta de utilidad para la prevención y para la planificación de tratamientos, así como para conocer, en este sentido, el efecto mediador de dichas estrategias -que son modificables o entrena bles- en los rasgos de personalidad, lo que constituye un aporte para el diseño y contenido de programas de salud mental infantil.

The aim of this study was to propose and analyze two models of associations to explain the relationships between Extraversion and Neuroticism traits, emotional regulation strategies cognitive reappraisal (CR) and suppression of emotional expression (SEE) and anxiety and depression in children 9 to 12 years old. For this, 230 children of both genders of those ages were evaluated in these variables and the models were compared by Path Analysis. The results showed that CR presented a total mediating effect on the relationship of Extraversion with anxiety, which was not observed for depression. The SEE submitted a partial mediating effect on the relationship of Neuroticism with anxiety and depression. These results have value to expand the knowledge available about the effect of these traits on clinical symptomatology which is useful for the prevention and treatment planning as well as for such an effect is through strategies that are themselves modifiable and/or trainable what constitutes an contribution for the design and content of children's mental health programs.

O objetivo deste trabalho foi propor e analisar os modelos de associações para explicar as relações entre os rasgos Extroversão e Neuroticismo, as estratégias de regulação emocional reavaliação cognitiva (RC) e suspensão da expressão emocional (SEE) e a ansiedade e depressão em crianças de 9 a 12 anos de idade. Avaliaram-se 230 crianças de ambos os gêneros de ditas idades nas variáveis mencionadas e se contrastaram os modelos mediante Análise de Caminhos (Path Analysis). Os resultados mostraram que a RC apresentou m efeito mediador total na relação da Extroversão com a ansiedade, coisa que não foi observada para a depressão. A SEE apresentou um efeito mediador parcial na relação do Neuroticismo com a ansiedade e com a depressão. Estes resultados possuem valor para ampliar o conhecimento disponível respeito do efeito destes rasgos sobre a sintomatologia clínica o que resulta de utilidade para a prevenção e planificação de tratamentos, assim como para conhecer que dito efeito é através de estratégias que são em si mesmas modificáveis e/ou treináveis o que constitui um impacto para o desenho e conteúdo de programas de saúde mental infantil.

La planificación implica la habilidad para identificar y organizar secuencias de acciones con el fin de alcanzar metas específicas. En la literatura se observan resultados dispares respecto de cuáles son los mejores predictores de esta capacidad en niños. Nuestro objetivo en este trabajo fue identificar en qué medida la voluntad de control, el control inhibitorio perceptual, la memoria de trabajo y la inteligencia fluida explican tal capacidad en niños que inician la educación primaria básica. La muestra estuvo conformada por 289 participantes de entre 6 y 7 años de edad. Los resultados indicaron que únicamente la inteligencia fluida y la memoria de trabajo se asociaban y explicaban la capacidad de planificar. Discutimos las implicaciones de estos resultados para el diseño de futuras investigaciones.

Planning involves the ability to identify and organize sequences of actions to achieve specific goals. In scientific literature different results are observed about which are the best predictors of this capacity in children. The aim of this study is to identify to what extent effortful control, perceptual inhibitory control, working memory and fluid intelligence explain this ability in children who start basic primary education. The sample consisted of 289 participants aged between 6 and 7 years old. The results indicated that only fluid intelligence and working memory were associated with and explained planning ability. The implications of these results for the design of future research are discussed.
