Understanding and Representing Space

The concern of this chapter is in coding the shape of objects, rather than locating them. Two main points are considered. One is to pull out the differences in shape information from touch compared to vision. The chapter suggests specifically that there is a major difference between touch and vision which is often neglected. The second point is to suggest that the distinction between identifying a shape and coding its location is not absolute because in some cases, identification depends on orientation. This chapter begins by citing a brief report on the evidence for the distinction between shape identification and location which shows the distinction obtained in both vision and touch. Findings on shape coding in vision and then in touch are explored next. Finally, the section in this chapter on orientation suggests that, for shape, the ‘where/what’ distinction is not complete.
