Recent investigations of visual perception in Aberdeen

The talk will concern investigations of spatial perception. It will present three sets of experiments. In the first set, a new method derived from Bartel's studies was used to investigate sex differences in spatial perception. Consistent differences between men and women were found, the men showing greater distance constancy in relation both to real and to depicted distances. One of the two tasks was also used to test two groups of students of architecture with varying degrees of experience. In the second set of experiments, the relationship between perceived similarity amongst simple geometric solids and projections arising from rotation of the typical contour of the solids are examined. The results indicate that (1) judgments of similarity are affected by pronouncedness of typical contours, and (2) similarity of simple geometrical solids is an asymmetrical attribute. In the third set of experiments, the role of symmetry in the encodement of spatial orientation is explored. The notion that enantiomorphic (e.g. 'b' v 'd') confusions are "spinoffs" of spatial encoding is examined.
