Delay in Retention of Forms

Abstract

10 forms were drawn on the palms of 48 subjects who were without vision. Subjects were then required haptically to explore three forms and choose the drawn shape. Three intervals, 0, 5, and 15 sec., were inserted between the presentation of the drawn form and the choice. It was expected that there would be a decline in the accuracy of form recognition with an increase in delay. Form recognition was significantly superior with no delay and loss of shape information seems to occur rather quickly since there was no significant difference in the accuracy of form recognition between the two longer delays.
