Tactile Scanning and Memory for a Spatial Display By Blind Students

Abstract

A primary purpose of maps is to convey information about space and spatial relationships. This study was an attempt to determine whether specific training in scanning a tactile display would enable blind students to more effectively organize the spatial relationships presented than would students not so trained. Thirty-six braille students in grades 4 to 12 were asked to inspect a tactile display consisting of 9 removable symbols. After inspection, the 9 symbols were removed and the students were asked to replace the parts in their correct location. There were 2 groups: a control group that received no training and an experimental group that was trained to systematically search the display using a vertical search technique. The results showed that the students in the lower grade levels benefited most from the training and were superior to the control group in the same grades. However, training interfered with the performance of the students in the upper grade levels (10 to 12), with the control group performing better than the experimental group. Apparently, training is most effective before strong habits have been established.
