Differences in how the two hemispheres of the brain handle spatial information were studied with blind subjects and blindfolded sighted subjects. The performances of all groups declined as the relative disorientation between the target and its duplicate increased, suggesting that visual imagery is not crucial to mental rotation. (Author/SEW)

Visual recognition, navigation, tracking, and imagery are posited to involve some of the same types of representations and processes. The first part of this paper develops a theory of some of the shared types of representations and processing modules. The theory is developed in light of neurophysiological and neuroanatomical data from non-human…
