Mixed reference frames for dynamic inhibition of return.
Reference frames mediating inhibition of return (IOR) in dynamic displays were investigated by comparing the effects of a cue in simple versus extended objects. Experiment 1 replicated S. P. Tipper, B. Weaver, L. M. Jerreat, and A. L. Burak's (1994) finding of location- and object-based IOR for boxes rotating about fixation. In Experiments 2 and 3, the boxes were replaced by two boomerang-shaped objects. Response times were slowed to all target locations across a cued object. They were also slowed to locations vacated by the uncued region of the cued object-evidence for a representation the authors call the "perceptual footprint." Whereas an object served as the medium for location-based IOR for B. S. Gibson and H. Egeth (1994), the environment served as the medium for object- and location-based IOR in Experiments 2 and 3. This suggests that (a) frames of reference may be considered hierarchically and (b) nesting of frames is context dependent.
