Frequency-based IOR is not "true" IOR Prime, David J.
Abstract
Auditory frequency cues can influence attention orienting in auditory frequency space; cues that match targets in frequency have a facilitatory effect on reaction time and accuracy for cue-target intervals of up to two seconds (Ward, 1997). Mondor, Breau, and Milliken (1998) found that this facilitatory effect can reverse to an inhibitory effect at cue-target intervals longer than 450 msec under some conditions. Mondor et al. referred to this effect as frequency-based Inhibition of Return (IOR). The present work demonstrates that inhibitory effects are not found in frequency target-target experiments (Experiment 1) or in cue-target experiments in which the experimental task reduces the probability that response inhibition to the cue will affect reaction time (Experiment 2). These results show that frequency-based IOR can be empirically distinguished from spatial IOR and that inhibitory effects in frequency cue-target experiments may arise from response inhibition to the cue. The present work, as well as functional and neurophysiological arguments, support the position that the term IOR should be reserved for inhibitory spatial effects.

Auditory frequency cues can influence attention orienting in auditory frequency space; cues
that match targets in frequency have a facilitatory effect on reaction time and accuracy for
cue-target intervals of up to two seconds (Ward, 1997). Mondor, Breau, and Milliken (1998)
found that this facilitatory effect can reverse to an inhibitory effect at cue-target intervals
longer than 450 msec under some conditions. Mondor et al. referred to this effect as
frequency-based Inhibition of Return (IOR). The present work demonstrates that inhibitory
effects are not found in frequency target-target experiments (Experiment 1) or in cue-target
experiments in which the experimental task reduces the probability that response inhibition to
the cue will affect reaction time (Experiment 2). These results show that frequency-based
IOR can be empirically distinguished from spatial IOR and that inhibitory effects in
frequency cue-target experiments may arise from response inhibition to the cue. The present
work, as well as functional and neurophysiological arguments, support the position that the
term IOR should be reserved for inhibitory spatial effects.
