Active and passive tactual recognition of form.
Subjects (N = 30) actively touched forms with the preferred palm or were restricted to passive touch, where forms were either statically or sequentially pressed on the palm. Visual matches to tactual standards were made with unlimited stimulus exposure time. Active touch was superior to both forms of passive touch in recognition accuracy. The provision of sequential presentations and stimulus change failed to aid passive touch.
