The role of executive function in reading comprehension among beginning readers.

Abstract

Empirical evidence supports the importance of executive function (EF) in reading, but the underlying mechanism through which EF contributes to the reading process is unclear. The present study examined the direct and indirect effects of EF on reading comprehension through the indirect pathway of language and cognitive skills (i.e., syntactic awareness and text-connecting inferencing) among the beginning readers. The sample included one hundred and sixty-five 2nd and 3rd grade students. The participants were tested on working memory (visuospatial working memory and verbal working memory) and inhibition (prepotent response inhibition and cognitive inhibition), and their syntactic awareness, inference-making, and reading comprehension. The unitary EF construct was obtained by means of confirmatory factor analysis based on the structure of EF in middle childhood suggested in developmental studies. Structural equation modelling was used to examine the direct and indirect effects of EF on the reading outcome. The findings indicated that EF has a direct effect on reading comprehension among the beginning readers. The indirect pathway showed that EF supports the ability to evaluate on grammatical structure of sentences (i.e., syntactic awareness) during reading. However, the indirect effect of EF on reading via inference-making ability is insignificant. The findings highlight the contributions of EF to reading and provide empirical evidence to the hypothetical relation between EF and language skills suggested in DIER (Kim, 2020, Resarch Quarterly, 50, 459). It further extends our knowledge on the roles of EF in the reading process among the beginning readers. Future research directions are implicated as well.
