Children's verbal working memory: relative importance of storage, general processing speed, and domain-general controlled attention

This study evaluated multiple constraints of verbal working memory in typically developing 7- to 11-year-olds. Multiple measures of verbal working memory and the predictors-short-term memory storage, general speed, and domain-general controlled attention were used. General linear modeling (GLM) showed that storage and the efficiency of controlled attention (i.e., speed of updating information during attention switching) contributed to significant variance in children's verbal working memory. In a secondary analysis verbal storage and domain-general attention (focus switching accuracy and speed of updating on switch) emerged as significant predictors. Results suggest domain-general attention and verbal storage mechanisms to be independent constraints of verbal working memory.     

Value congruence and teachers’ work engagement: The mediating role of autonomous and controlled motivation

This study aimed to examine the importance of value congruence in work engagement and to extend the previous literature by investigating the potential mediating effects of autonomous and controlled motivation in this relationship. The Perceived Value Congruence, Autonomous and Controlled Motivation and Work Engagement scales were administered to 767 teachers in Mainland China. Correlation analysis revealed that value congruence, autonomous and controlled motivation and work engagement were significantly correlated with each other. Furthermore, structural equation modeling (SEM) analysis showed that value congruence exerted its indirect effect on teacher’s work engagement through the mediating effect of autonomous and controlled motivation. These findings provide a new perspective to explain the complex association between value congruence and work engagement. The possible explanations and the research limitations are discussed.
