Zusammenfassung
The relative motion between observers and objects produces structured changes to the retinal input. To what extent do we use such spatio-temporal signatures for recognition? This question was addressed by testing observer’s recognition of visually-similar or visually-dissimilar objects moving with characteristic motions. An identification task assessed whether observers relied on the object’s spatio-temporal signatures, 3D shapes, 2D views,or combination of the three. We found that altering an object’s motion pattern following learning impaired identification. However, these new motion patterns only changed spatio-temporal signatures from study to test. Thus, observers appear to use these signatures as one cue to object identity.
