GOAL:
This experimental research project focuses at the possibilities and limits of adult learning in two particularly important cognitive domains, namely language learning and high-level cognitive control coined as executive functioning. In language acquisition, we study the earliest stages in learning of new words and their inherent regularities, including orthographic regularities and morphological structure. Both normal healthy adults and individuals with aphasia serve as subjects. Part of the studies will be coupled with structural or functional neuroimaging measurements in order to shed light on the brain correlates of word learning. In executive functioning, we explore the trainability of two executive processes in normal adults, namely inhibition of irrelevant responses and flexible shifting between different task sets. This research should contribute to a better understanding of the dynamics of learning of specific aspects of language and executive function, as well as have implications for second language learning, compensation for aging effects, and cognitive retraining.
