Abstract:
Both viewpoint-invariance and viewpoint-dependence have been
obtained in previous object priming studies. Some theories of
object recognition propose that viewpoint-invariant priming will be
found when the same parts are recovered from different views, and
viewpoint-dependent priming will be found when different parts are
recovered from different views. In this study, participants
sketched and then named briefly presented objects at test, after
viewing identical and depth-rotated prime objects during an
encoding phase. Compared with test objects, depth-rotated prime
objects were presented in views that allowed either the same or
different parts to be recovered. Contrary to predictions from
viewpoint-invariance theories, viewpoint-dependent priming (greater
naming accuracy for identical than for depth-rotated objects) was
observed in both same- and the different-part conditions.
Furthermore, this viewpoint-dependent priming did not depend on the
hemisphere of initial test presentation. Hence, this form-specific
task created a situation in which viewpoint-dependent
representations underlie priming.
