The significance of angular difference on the reaction time of identifying rotated three-dimensional objects

Abstract
Does the angular difference of 3D familiar objects affect the reaction time for identifying whether two images are “same” or “different”. Viewer-centred theories suggests so (Tarr & Pinker, 1989; Jolicoeur, 1990), as do I, that when participants are presented with a pair of 3D familiar objects rotated through depth plane at varying angles (30, 60, 120, 150 degrees) and asked to state whether they think the image are the “same” or “different” as angular difference increases so will the reaction time. The results of 107 participants showed a significant difference between rotation of 30 and 150 degrees t(106) = -8.757, p<.001 which supports the hypothesis and previous research (Shepard & Metzler, 1971; Shepard & Cooper, 1973; Shepard & Feng 1972; Sayeki 1981)   which backs viewer centered theories.

The significance of angular difference on the reaction time of identifying rotated three-dimensional objects
    As humans we are easily able to recognise objects under many different conditions with what appears to be little effort. Recognising objects is a key parts of human vision and how this function is achieved has been extensively researched. There are two opposing theories of object recognition, the object centred theory and the viewer-centred theory which suggest different way for which visual recognition takes place. The object centred theory suggests that there are constant cue for recognising an object under most viewing conditions and the viewpoint of an object is irrelevant even in novel viewpoints no mental rotation is required. One key example of this theory is Biederman (1987) Recognition-by-components (RBC), who put forward the idea that we recognise objects through building structural descriptions of simple geometric shapes (geons) and match these to the utmost alike object representation stored in our memory....
