Abstract

ABSTRACT: A picture–word interference paradigm tracked patterns of activation during picture naming in 87 individuals (age range 17–80 years old). Distractor words were presented at stimulus onset asynchronies (SOAs) of −200, −100, and 0 ms bearing a has a-, location, or no relationship to the picture. Analyses of group naming reaction times revealed significant facilitation effects for both semantic relation types for all age groups. Analyses of temporal patterns of activation revealed significant effects primarily at SOAs of −200 and −100 ms. These findings provide evidence that both thematic relations are particularly salient in how semantic knowledge is organized, and that the patterns of effects from these semantic relations remain the same as one ages.
