| Research Abstract |
This study investigates whether development of executive function affects linguistic knowledge acquisition and utilization. Study 1 investigated individual differences of language-communication skills and executive functions(verbal working memory and inhibition function). Study 2 conducted a visual world paradigm experiment, where five-and six-years-old children and adults comprehended the color adjective phrases. In Study 3, adults participated a visual world paradigm experiment, where the visual attention was controlled by the visually contrastive objects and a sentence comprehension process. In summary, inhibition function primarily contributes to the development of language processing and its contribution to the knowledge acquisition is small.
