ABSTRACT The purpose of this study was to examine the impact of mindfulness training on selective attention, sustained attention, and inhibitory control in children aged 9 to 11. To achieve this, 114 students participated in the mindfulness program "Sitting Still Like a Frog" and were assessed before and after the program using tests that measure these variables. A quasi-experimental study with counterbalancing was conducted to minimize the learning effect, involving both an experimental group and a control group. The results indicated an impact of the mindfulness practice on the measure of selective attention, although no significant effects were observed for sustained attention or inhibitory control measures. Considering the role of attentional skills in children's academic activities, this outcome underscores the importance of contemplating mindfulness practices in the school context.

RESUMEN El propósito de este trabajo consistió en estudiar el impacto de un entrenamiento en mindfulness sobre la atención selectiva, la atención sostenida y el control inhibitorio en niños de entre 9 y 11 años. Para ello, 114 alumnos participaron del programa de mindfulness Tranquilos y atentos como una rana, siendo previa y posteriormente evaluados con pruebas que recogen medidas de dichas variables. Se realizó un estudio de tipo cuasiexperimental con contrabalanceo para reducir el efecto aprendizaje. Se trabajó con un grupo experimental y un grupo control. Los resultados mostraron un impacto de la práctica sobre la medida de atención selectiva, no así para las medidas de atención sostenida ni de control inhibitorio. Teniendo en cuenta el rol de las habilidades atencionales en la actividad académica de los niños, este resultado resalta la importancia de pensar las prácticas de mindfulness en el contexto escolar.

Resumen: El propósito de esta investigación consistió en estudiar el rol del vocabulario, la memoria de trabajo, la teoría de la mente y la atención sostenida en la comprensión de narraciones orales y la generación de inferencia en niños de entre 7 y 11 años. Para ello, se utilizaron las habilidades de comprensión lectora como criterio para establecer los grupos de cohorte del estudio. La muestra, conformada por 126 niños colombianos hispanohablantes, fue evaluada en tareas de comprensión de narraciones orales, así como mediante pruebas estandarizadas en vocabulario, memoria de trabajo, teoría de la mente y atención sostenida. Los resultados mostraron diferencias significativas entre el grupo de baja comprensión lectora respecto al grupo de comparación con mejores desempeños en comprensión en la medida de vocabulario y en la medida de comprensión de narraciones con apoyos visuales, como producto de una diferencia significativa en la respuesta a preguntas de inferencia emocional. El análisis correlacional mostró vínculos significativos entre el vocabulario y todas las medidas de comprensión evaluadas. Por su parte, la memoria de trabajo se correlacionó con todas las medidas de desempeño en comprensión, excepto con la respuesta a preguntas inferenciales. Finalmente, la teoría de la mente mostró una correlación significativa con la respuesta a preguntas de inferencias emocionales y con las medidas de comprensión de narraciones sin apoyos visuales.

Resumo: O objetivo desta pesquisa foi estudar o papel do vocabulário, da memória de trabalho, da Teoria da Mente e da atenção sustentada na compreensão de narrativas orais e na geração de inferência em crianças de 7 a 11 anos. Para isso, foram utilizadas as habilidades de compreensão de leitura como critério para estabelecer os grupos de coorte do estudo. Um total de 126 crianças colombianas, hispano-falantes, foram avaliadas por meio de tarefas de compreensão de narrativas orais, testes padronizados de vocabulário, memória de trabalho, Teoria da Mente e atenção sustentada. Os resultados indicaram diferenças significativas entre o grupo de baixa compreensão leitora em relação ao grupo de comparação, com melhores desempenhos em compreensão no teste de vocabulário e no teste de compreensão de narrativas com apoios visuais, como resultado de uma diferença significativa na resposta a perguntas de inferência emocional. A análise correlacional mostrou vínculos significativos entre o vocabulário e todas as medidas de compreensão avaliadas. Além disso, a memória de trabalho correlacionou-se com quase todas as medidas de desempenho em compreensão, exceto com a resposta a perguntas inferenciais. Finalmente, a Teoria da Mente apresentou uma correlação significativa com a resposta às perguntas de inferências emocionais e com as medidas de compreensão de narrativas sem apoio visual.

Abstract: The purpose of this study was to analyze the role of vocabulary, working memory, Theory of Mind, and sustained attention in the comprehension of oral narratives and the generation of inferences in children aged 7 to 11. Reading comprehension skills were used as the criterion to establish the study's cohort groups. A total of 126 Spanish-speaking Colombian children participated in the study. They were assessed using tasks that measured comprehension of oral narratives, as well as standardized tests of vocabulary, working memory, Theory of Mind, and sustained attention. The results indicated a significant difference in vocabulary between the group of poor comprehenders and the comparison group with better comprehension performance. The poor comprehenders also performed worse than the comparison group in the narrative comprehension test with visual support, as a result of significant differences in responding to emotional inference questions. The correlational analysis showed that the vocabulary variable was associated with all measures of oral narrative comprehension. Additionally, working memory correlated with almost all measures of oral narrative comprehension, except for answering inference questions when the text did not have visual support. Finally, Theory of Mind demonstrated a significant correlation with answering emotional inference questions and the measures without visual support.

RESUMO Trabalho e atividade podem ser importantes fontes de enriquecimento cognitivo. Atividades que são mais desafiadoras quanto às funções cognitivas postas em prática se associam a menor risco de declínio cognitivo em idade avançada. Objetivo: O objetivo do presente estudo é avaliar o impacto da complexidade ocupacional e das tarefas domésticas em três domínio cognitivos (memória episódica verbal, linguagem e funções executivas) em idosos residentes na comunidade. Métodos: Foi realizada uma análise de trilha com o uso de procedimento de equações estruturais em 120 participantes, avaliados por meio de: questionário das principais atividades ocupacionais e tarefas domésticas da vida, bem como bateria de avaliação neuropsicológica para memória, linguagem e funções executivas. Resultados: A análise dos pesos de regressou mostrou que a complexidade nas tarefas domésticas apresenta efeitos moderados nas funções executivas (β=0,19; p=0,027) e que a complexidade ocupacional do trabalho remunerado teve efeitos sobre a memória (β=0,26; p=0,008), linguagem (β=0,38; p<0,001) e funções executivas (β=0,55; p<0,001). Conclusão: O trabalho remunerado promove a reserva cognitiva, em contraste com as atividades domésticas, que parecem ter impacto moderado na cognição. As diferenças na complexidade das atividades não apenas impactam o status econômico e social e as possibilidades das pessoas, mas também podem determinar diferentes cursos de envelhecimento e risco cognitivo. avançada Objetivo verbal comunidade Métodos 12 participantes vida Resultados β=0,19 β019 β 0 19 (β=0,19 p=0,027 p0027 p 027 β=0,26 β026 26 (β=0,26 p=0,008, p0008 p=0,008 , 008 p=0,008) β=0,38 β038 38 (β=0,38 p<0,001 p0001 001 β=0,55 β055 55 (β=0,55 p<0,001. .

ABSTRACT Work and activity could be an important source of cognitive enrichment. Activities that are more challenging concerning the cognitive functions that are put into practice are associated with lower risk of cognitive decline in old age. Objective: The present study aimed to assess the impact of occupational complexity and household tasks in three cognitive domains (verbal episodic memory, language, and executive functions) in older adults residing within the community. Methods: A trail analysis was executed, using the structural equations procedure in 120 participants assessed with main lifetime occupational activity and household tasks questionnaire, as well as a neuropsychological assessment battery for memory, language, and executive functions. Results: The regression weights analysis indicated that complexity in household chores showed moderate effects on executive functions (β=0.19; p=0.027) and that occupational complexity of paid work showed effects on memory (β=0.26; p=0.008), language (β=0.38; p<0.001), and executive functions (β=0.55; p<0.001). Conclusion: Paid work promotes cognitive reserve, contrary to household activities which seem to have a moderate impact on cognition. Differences in activity complexity not only impact people´s economic and social status and possibilities but can also determine different courses of aging and cognitive risk. enrichment age Objective verbal community Methods executed 12 questionnaire Results β=0.19 β019 β 0 19 (β=0.19 p=0.027 p0027 p 027 β=0.26 β026 26 (β=0.26 p=0.008, p0008 p=0.008 , 008 p=0.008) β=0.38 β038 38 (β=0.38 p<0.001, p0001 p<0.001 001 p<0.001) β=0.55 β055 55 (β=0.55 p<0.001. .

ABSTRACT The objective of this study was to analyze if the need for belonging and fear of rejection are associated with the frequency of alcohol consumption and the amount of alcohol consumed. The sample consisted of 399 adolescents, with a mean age of 15.14 years (SD = 1.86). The inventory of the need for belonging and questionnaire on alcohol consumption was administered. Significant positive correlations were found between the amount of alcohol that adolescents consume, and the need for belonging and the fear of rejection factor, as well as between frequency and fear of rejection. Significant differences were verified between abstinent adolescents and those who consume alcohol moderately, and those who abuse alcohol abusively. Also, it was found that the need for belonging mediates the relationship between gender and alcohol consumption. In conclusion, need for belonging was closely related to alcohol consumption, in particular to fear of rejection.

RESUMEN El objetivo de este estudio fue determinar si la necesidad de pertenencia y el miedo al rechazo se relacionan con la frecuencia y la cantidad de consumo de alcohol. La muestra estaba compuesta por 399 adolescentes, con una edad media de 15.14 años (DE = 1.86). Materiales: Se administró el inventario necesidad de pertenencia y un cuestionario de consumo de alcohol. Se hallaron correlaciones significativas positivas entre la cantidad de alcohol que los adolescentes consumen con la necesidad de pertenencia y el factor miedo al rechazo, y entre frecuencia y miedo al rechazo. También, se encontraron diferencias significativas entre los adolescentes abstinentes y los que consumen alcohol de forma moderada con los que lo hacen de forma abusiva. Asimismo, a partir de un modelo puesto a prueba se descubrió que la necesidad de pertenencia media la relación entre el género y el consumo de alcohol. A partir de estos resultados, se puede concluir que la necesidad de pertenencia mostró estar vinculada con el consumo de alcohol, en particular el factor miedo al rechazo que actúa como mediador entre la relación de género y el consumo de alcohol.

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

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

Abstract: The aim of this paper is to evaluate the effects of a program to improve reading comprehension. The study was conducted within the framework of the Citizenship class of first-year students in an Argentine secondary school. A total of 63 students took part in a quasi-experimental study, which used pre-test and post-test assessment, and a control group. The results show that the intervention had effects on effective reading, inferences, general comprehension, and knowledge of the subject taught in the class where the program was implemented. The findings are discussed in light of the importance of contextualizing intervention proposals according to the demands of the school environment.

Resumen: El objetivo del presente trabajo consiste en evaluar los efectos de una propuesta para mejorar la comprensión de textos. La intervención se desarrolló en el marco de la asignatura Construcción de ciudadanía, con alumnos que asistían al primer año de una escuela secundaria argentina. Se trata de un estudio cuasi-experimental, pre-test y pos-test, con grupo control, en el que participaron 63 estudiantes. Los resultados mostraron que la intervención tuvo efectos en eficacia lectora, inferencias, comprensión general y el conocimiento de la asignatura en la que se aplicó el programa. Se discuten los hallazgos de la investigación a la luz de la importancia de contextualizar las propuestas de intervención en relación con las demandas del ámbito escolar.

Resumen El vocabulario se refiere al conocimiento acerca de las palabras que maneja y conoce una persona, y juega un rol importante en el desarrollo y la ejecución de gran cantidad de habilidades cognitivas. El objetivo de este estudio fue evaluar el tamaño del efecto del vocabulario en ambas modalidades, profundidad y amplitud, en las habilidades de resolución de problemas aritméticos. Con este propósito se realizó un meta-análisis sobre 16 estudios relacionados al tema. Se incluyeron estudios posteriores al año 2000, con niños entre 3 y 13 años y sin problemas neurológicos. Los resultados obtenidos mostraron un efecto moderado y significativo del vocabulario, tanto con respecto a la amplitud como a la profundidad del mismo, sobre la resolución de problemas aritméticos de tipo lingüístico. Los resultados también muestran un índice elevado de heterogeneidad, que puede ser explicado por las inconsistencias a la hora de evaluar los constructos.

Abstract Vocabulary refers to the knowledge about words that a person uses and understands. It plays a preponderated role in the development and execution of many cognitive abilities. The aim of this study was to evaluate the effect size of vocabulary in both of its modalities, breadth and depth, regarding the ability to solve arithmetic word problems. For this purpose, we conducted a meta-analysis on 16 studies related to the subject. We included studies done after 2000, with children aged 3 to 13 and without neurological problems. Our results showed a moderate but statistically significant effect of vocabulary on the ability to solve arithmetic word problems, without difference between its modalities. Results also show a high heterogeneity index that can be explained due to inconsistencies in the way the constructs are measured.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Para ello se realizaron dos estudios. En el Estudio 1 se diseñó y validó la Batería Informatizada de Memoria de Trabajo Viso-Espacial (BIMeT-VE) con 212 estudiantes universitarios hispanoparlantes. En el Estudio 2, en el que participaron 114 estudiantes universitarios hispanoparlantes se estudió la relación entre la memoria de trabajo viso-espacial, la velocidad de procesamiento y la inteligencia general. Los resultados mostraron que la inteligencia general está directamente relacionada con la velocidad de procesamiento y con la habilidad de mantener información viso-espacial por breves períodos de tiempo, e indirectamente por la habilidad de procesar concurrentemente información viso-espacial.

Perceived emotional intelligence is a set of skills that allow managing and serving emotional information. It includes attention to emotions, the clarity with which feelings are perceived, and the ability to repair the negative emotional states. Participation in extracurricular activities during adolescence has been considered a resource for the development of skills and competencies. Objective: to study if differences in emotional intelligence perceived according to the participation in extracurricular activities. Sample: 399 adolescents, with a mean age of 15.14 years (SD = 1.86) from two private schools in Buenos Aires City. Materials: the TMMS-21, which evaluates the three components of emotional intelligence, and a socio-demographic questionnaire to gather information on extracurricular activities were administered. Results: We found differences in the level of clarity that adolescents reported, being higher for those who participated in extracurricular activities. We also found that adolescents participating in sports reported higher levels of clarity then those involved in artistic activities. Conclusion: Participation in extracurricular activities seems to provide teens with tools to decompose, identify and catalog the emotions more easily. In addition, the difference found between sports and artistic activities may be due to the fact that a higher level of introspection, motivated by the artistic activities, can increase the level of self-criticism regarding one's clarity when it comes to perceiving emotions, which could be reflected in a lower level of perception of the capacity to label different emotional states

La inteligencia emocional percibida se define con una serie de habilidades que permiten manejar y servirse de la información emocional. Está compuesta por la atención a las emociones, la claridad con la que se perciben los sentimientos y la capacidad de reparación de los estados emocionales negativos. La participación en actividades extracurriculares durante la adolescencia se está considerando un recurso para el desarrollo de habilidades y competencias. Objetivo: Estudiar diferencias en la inteligencia emocional percibida según la participación en actividades extracurriculares. Muestra: 399 adolescentes, con una edad media de 15.14 años (DE = 1.86) alumnos de dos escuelas privadas de educación media de la Ciudad Autónoma de Buenos Aires. Materiales: Se administró a los adolescentes la TMMS-21 que evalúa los tres componentes de la inteligencia emocional y un cuestionario sociodemográfico para recabar información sobre las actividades extracurriculares realizadas. Resultados: Se hallaron diferencias en el componente de la inteligencia emocional claridad, siendo mayor para aquellos que participan en actividades extracurriculares. También se halló que los adolescentes que participaban en actividades deportivas reportaron mayores niveles de claridad que los que participan en actividades artísticas. Conclusión: La participación en actividades extracurriculares parece brindar a los adolescentes herramientas para desglosar, identificar y catalogar las emociones con más facilidad. Además, la diferencia hallada entre las actividades deportivas y artísticas se puede deber a que el mayor nivel de introspección motivado desde las actividades artísticas puede aumentar el nivel de autocrítica con respecto a la propia capacidad de claridad a la hora de percibir las emociones, reflejado en el reporte de un menor nivel de percepción de capacidad para etiquetar los estados emocionales
