Abstract

Uninformative auditory frequency cues have a facilitatory effect on reaction time and accuracy of detection and intensity discrimination of target tones for cue-target intervals of up to 3 sec (Green & McKeown, 2001; Ward, 1997). Under some conditions, however, this facilitatory effect can reverse to an inhibitory effect at cue-target intervals longer than 450 msec (Mondor, Breau, & Milliken, 1998). The present work demonstrates that such inhibitory effects are not found in target-target experiments (Experiment 1) or in cue-target experiments requiring a go-no-go discrimination of the target (Experiment 2), whereas they do appear in the paradigm used by Mondor et al. (1998, Experiment 3), albeit unaffected by the similarity of cue and target. Thus, the frequency-based inhibitory effects sometimes found in auditory cuing tasks can be distinguished empirically from those characterizing spatial inhibition of return (IOR), which are found in both target-target and go-no-go cue-target paradigms. The present work and functional and neurophysiological arguments all support the position that different mechanisms underlie spatial IOR and the inhibitory effects sometimes found in auditory frequency processing.
