The Impact Of Spatial Relevance On Auditory Frequency-based Inhibition Of Return In Different Paradigms

Auditory inhibition of return refers to slower responding to auditory stimuli at previously occupied spatial locations or when nonspatial feature were repeated. This research give the comparison between the cue-target paradigm and target-target paradigm; summarize the element of auditory inhibition of return; and introduce the dual-process model and the nature of the matching process occurring on the repeat-response trails.Combining the paradigms of location-based auditory IOR and frequency-based anditory IOR,This research adopt 2×2×3 within-subject design, including two experiments. The first experiment adopt cue-target paradigm, the second experiment adopt target-target paradigm. They both ask subjets to perform simple detection and sound localization tasks in order to explore the impact of spatial relevance on auditory frequency-based inhibition in different paradigms. The results showed:⑴In experiment 1, spatial relevance can increase the quantity of frequency-based anditory IOR, the discrepancy is significant;⑵In experiment 2, spatial relevance is important condition for occuring frequency-based anditory IOR;⑶In the target-target paradigm, in which IOR occurs in this task only on trails on which stimuli and responses are not repeated. Furthermore, the experiment clearly analyses and explains how spatial relevance influence frequency-based auditory inhibition of return, and provides experimental references and theoretical supports for current auditory IOR theory from a new point of view.
