Errors and latency of response as a function of order of presentation of tactile-visual stimuli in concept identification

A task using plastic geometric objects was designed to study concept identification through the tactile sense. The overall results of this study showed that errors and time to solution were similar in classifying visual and tactile information, but response latency was significantly longer in tactile than in visual concept identification. Also, there is some suggestive evidence that visual concept identification was facilitated with practice on a tactual task, whereas tactual concept identification was not facilitated by practice on a visual task.
