Abstract

Tested channel-switching theory in an RT experiment requiring 4 undergraduates to respond to either visual-visual or auditory-visual pairs separated by various interstimulus intervals. The main condition required a single response to the joint attributes of the pair; various control conditions investigated RT to the individual members of the pair. RT in the main condition was more rapid for auditory-visual pairs, and also in the control conditions due to the greater intensity of the auditory as opposed to visual 1st stimulus. There was no evidence for a modality effect per se, contrary to channel-switching theories that assume a delay at input occurs with intersensory pairings. Alternatives to this position, in particular a theory that assumes the delay occurs at output, are suggested. (15 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
