Abstract

The interactive effects of attention and semantic relation on event-related potential (ERP) waveforms were examined during a naming task in which thephysical stimulus array was the same across conditions, superimposed picture-word pairs were presented in which the meaning of the words and pictureswas congruent, semantically associated, or incongruent. In separate conditions, participants named words or pictures while ignoring the other stimulus. When words were attended, the superimposed pictures modulated the amplitude of P240 waves at posterior sites compared with when words were presented individually. but had no effect on N450 waves. In contrast, when pictureswere attended to, the superimposed incongruent words elicited larger amplitude N450 waves at anterior sites than did congruent words or individually presented pictures. These effects affirm the independent processing of words and pictures during attention and are consistent with automatic and controlled processing of words and pictures. respectively. They also illustrate the endogenous nature of these late ERP waves. (C) 2000 Elsevier Science B.V. All rights reserved.
