What is the contribution of executive functions to communicative-pragmatic skills? Insights from aging and different types of pragmatic inference

Tijdschriftbijdrage - Tijdschriftartikel

The role of executive functions in supporting the pragmatics of communication has been extensively examined in clinical populations, but is still under-explored in healthy aging. In this study we addressed the role of executive skills, including inhibition, working memory, and cognitive flexibility, in older adults' communicative-pragmatic abilities. Pragmatics was extensively assessed by measuring the understanding of figurative language, narrative texts, humor, and implicatures. A hierarchical regression analysis using composite scores evidenced a global effect of executive functions on communicative-pragmatic abilities, beyond demographic and theory of mind aspects. More fine-grained analyses showed that working memory was the strongest predictor of all pragmatic tasks. Specifically, comprehending narratives and humor seemed to capitalize primarily upon working memory, whereas figurative language and implicatures relied on working memory and to some extent cognitive flexibility. Conversely, inhibition did not stand out as a robust predictor of pragmatics. We argue that working memory allows for the simultaneous consideration of multiple pieces of information needed for pragmatic inferencing, and that only once working memory has played its role other executive aspects, such as cognitive flexibility and inhibition, might come into play. Overall, this study highlights the diverse role of executive skills in pragmatics in aging, and more generally contributes to shed light on pragmatic competence in older adults.
