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

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

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

Execution and pauses in writing narratives: processing time, cognitive effort and typing skill.

At the behavioural level, the activity of a writer can be described as periods of typing separated by pauses. Although some studies have been concerned with the functions of pauses, few have investigated motor execution periods. Precise estimates of the distribution of writing processes, and their cognitive demands, across periods of typing and pauses are lacking. Furthermore, it is uncertain how typing skill affects these aspects of writing. We addressed these issues, selecting writers of low and high typing skill who performed dictation and composition tasks. The occurrences of writing processes were assessed through directed verbalization, and their cognitive demands were measured through interference in reaction times (IRT). Before writing a narrative, 34 undergraduates learned to categorize examples of introspective thoughts as different types of activities related to writing (planning, translating, or revising). Then, while writing, they responded to random auditory probes, and reported their ongoing activity according to the learned categories. Convergent with previous findings, translating was most often reported, and revising and planning had fewer occurrences. Translating was mostly activated during motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes can be characterized as being typical of pauses, since translating was activated to a similar extent as the other two processes. Regarding cognitive demands, revising is likely to be the most demanding process in narrative writing. Typing skill had an impact on IRTs of motor execution. The demands of execution were greater in the low than in the high typing skill group, but these greater demands did not affect the strategy of writing processes activation. Nevertheless, low typing skill had a detrimental impact on text quality.
