Abstract

This study was an investigation of the association between executive functioning (EF) ability and language development in the latter half of the second year. Fifty-five typically developing 18- month-olds were brought into the lab. The elicited imitation with inappropriate object substitution (EIIOS) task was used as a developmentally sensitive measure of EF. Language acquisition was assessed using a real-time word learning task as well as a parent report measure of vocabulary size (MacArthur-Bates Communicative Development Inventory: Words and Sentences Version). Contrary to expectations, very few statistically significant associations were found between the EF measure and either language measure. Despite these findings there is still a need for research to identify an appropriate measure of EF in the latter half of the second year.
