| Abstract: | In this observational case study, a 13-year old boy, Carlo, who was born completely blind, was invited to explore and identify, a set of raised-line pictures without receiving feedback about the accuracy of his identification. He was then asked to explain, verbally or by drawing, why he believed that the names he suggested accurately identified the depicted objects. The study found that Carlo identified 62% of the target pictures. Most of his verbalizations contained descriptions of salient parts of possible object referents that fit the configuration of the raised lines. The findings of this case study support the notion that the identification of raised-line pictures is based on principles of the perception of the shape of objects, independent of tactile beliefs. These principles seem to overlap, at least partially, in vision and haptics. The findings, however, need to be replicated with a larger sample. (Contains 1 table and 3 figures.) |
