Numerous research on executive functions show evidence of their relation to language. Nonetheless, due to the complexity of executive functions that causes difficulties in defining and measuring them, details of that relationship are still not well defined. The majority of work done on this topic is based on studying children's development and language acquisition or special populations. Because of the dynamic nature of those constructs that change significantly throughout the lifespan, exploring their interactions in adult age would contribute to a better and more complete understanding of that relationship. Having that in mind, the objective of this research was to examine the relationship between specific executive functioning components and receptive language in adult age. The participants in the study were healthy adults (N=30) between the ages of 21 and 37 years. Executive functioning components of spatial working memory, planning, cognitive flexibility and cognitive inhibition were assessed with CANTAB battery of tests, whereas verbal working memory was tested with a subtest of WAIS-III test, the Memory for Digit Span. Peabody Picture Vocabulary Test (PPVT-III-HR) and Test for Reception of Grammar (TROG-2:HR) were administered to assess language skills. The results of regression analisys showed that the relationship exists between executive functions and understanding of grammatically complex sentences. The relationship between executive functions and simple sentences or receptive vocabulary was not found. These results could mean that the involvement of executive functions in language in adult age is required only in grammatically complex sentences that put greater demands on language processing. This finding is in agreement with similar foreign research. However, in order to enable drawing a valid conclusion on this topic, future studies should include more participants and different levels of syntactic complexity.
