The role of verbal and working memory skills in Turkish-speaking children's morphosyntactic prediction

Abstract

The current study investigated the contribution of multiple verbal and working memory (WM) skills to morphosyntactic prediction in Turkish-speaking 4- to 8-year-old children. In a visual world eye-tracking experiment, 76 children were presented with verb-final sentences with nominative and accusative case markers on the initial noun (e.g., the fast rabbit(nominative) horizontal ellipsis the carrot(accusative) eat(future) vs. the fast rabbit(accusative) horizontal ellipsis the fox(nominative) eat(future)) while they were looking at a visual display with three objects (e.g., rabbit, carrot, and fox). Importantly, the case markers on the initial noun could be used to predict the second noun in these sentences. The results revealed that when children's early productive vocabulary and language production skills were higher, the better and faster they were in predicting the upcoming noun. The episodic buffer, a component of WM, was also positively associated with children's morphosyntactic prediction abilities. The implications of these results for the mechanisms of linguistic prediction are discussed.
