Introducción. El objetivo principal de este estudio fue: a) investigar si los estilos cognitivos y la capacidad de memoria de trabajo puede predecir el rendimiento matemático y qué variables son más importante para predecir el rendimiento matemático, y b) para explorar si los estilos cognitivos y la capacidad de memoria de trabajo puede predecir el rendimiento matemático cuando se controlan el impacto del conocimiento previo de los estudiantes de matemáticas y la cantidad de tarea de matemáticas terminada.Método. La muestra de 183 niñas de la escuela K9 (15-16 años) fueron probados en (1) el estilo cognitivo de Witkin (Grupo de pruebas Figura Embedded) (2) Digit Span Backwards prueba (3) Cuestionario Homework (4) examen de Matemáticas. Los datos de esta investigación se analizaron mediante regresión múltiple estándar de SPSS.Resultados. Los resultados obtenidos de la regresión estándar indicaron que ambos predictores fueron correlacionados con el rendimiento matemático y consistentemente predijeron el rendimiento matemático. Además, los coeficientes estandarizados indicaron que el estilo cognitivo (β = .58) fue más fuerte predictor de rendimiento matemático que la capacidad de memoria de trabajo (β = .43). Después de controlar los conocimientos de estudiantes de matemáticas 'anterior y la cantidad de tarea de matemáticas terminado, las pruebas de regresión múltiple mostraron que el estilo cognitivo y la memoria de trabajo seguían siendo significativos predictores del desempeño matemático, pero los efectos de estas variables sobre el rend-miento matemático disminuido a .21 y .10, respectivamente.Discusión y conclusión. De acuerdo con los resultados obtenidos, hacer la tarea de matemáticas y los conocimientos de matemáticas previos, puede disminuir los efectos negativos de ser dependiente de campo y la baja capacidad de memoria de trabajo, en el rendimiento matemático de los estudiantes.

Abstract. The Monty Hall Dilemma (MHD) is an intriguing example of the discrepancy between people’s intuitions and normative reasoning. This study examines whether the notorious difficulty of the MHD is associated with limitations in working memory resources. Experiment 1 and 2 examined the link between MHD reasoning and working memory capacity. Experiment 3 tested the role of working memory experimentally by burdening the executive resources with a secondary task. Results showed that participants who solved the MHD correctly had a significantly higher working memory capacity than erroneous responders. Correct responding also decreased under secondary task load. Findings indicate that working memory capacity plays a key role in overcoming salient intuitions and selecting the correct switching response during MHD reasoning.

The Relationship

**The uploaded manuscript is still in preparation** In this study, we tested the relationship between visual arrays tasks and working memory capacity and attention control. Specifically, we tested whether task design (selection or non-selection demands) impacted the relationship between visual arrays measures and constructs of working memory capacity and attention control. Using analyses from 4 independent data sets we showed that the degree to which visual arrays measures rely on selection influences the degree to which they reflect domain-general attention control.

Internal Attention

AbstractPrevious studies have associated visual working memory (VWM) capacity with the use of internal attention. Retrocues, which direct internal attention to a particular object or feature dimension, can improve VWM performance (i.e., retrocue benefit, RCB). However, so far, no study has investigated the relationship between VWM capacity and the magnitudes of RCBs obtained from object-based and dimension-based retrocues. The present study explored individual differences in the magnitudes of object- and dimension-based RCBs and their relationships with VWM capacity. Participants completed a VWM capacity measurement, an object-based cue task, and a dimension-based cue task. We confirmed that both object- and dimension-based retrocues could improve VWM performance. We also found a significant positive correlation between the magnitudes of object- and dimension-based RCB indexes, suggesting a partly overlapping mechanism between the use of object- and dimension-based retrocues. However, our results provided no evidence for a correlation between VWM capacity and the magnitudes of the object- or dimension-based RCBs. Although inadequate attention control is usually assumed to be associated with VWM capacity, the results suggest that the internal attention mechanism for using retrocues in VWM retention is independent of VWM capacity.

The Relationship

Abstract This paper reports the findings of a study that investigated the relationship between phonological short-term memory (PSTM), working memory capacity (WMC), and the level of mastery of L2 grammar. Grammatical mastery was operationalized as the ability to produce and comprehend English passive voice with reference to explicit and implicit (or highly automatized) knowledge. Correlational analysis showed that PSTM was related to implicit productive knowledge while WMC was linked to explicit productive knowledge. However, regression analysis showed that those relationships were weak and mediated by overall mastery of target language grammar, operationalized as final grades in a grammar course.
