Accuracy of haptic object matching in blind and sighted children and adults

Abstract

In this study a haptic object matching task is used to examine the accuracy of identification of the object dimensions: texture, weight, volume and exact shape in four different participant groups: congenitally blind adults, sighted adults, congenitally blind children, and sighted children. The results show that age is more influential for the accuracy to identify object dimensions by touch than the visual status.
