TACTILE SENSITIVITY IN THE VISUALLY CHALLENGED AND NORMAL SUBJECTS – A COMPARATIVE STUDY

Blindness defined as visual activity less than 3/60 by Snellen’s chart or its equivalent. The present study shows that there is definitely superior capacity of tactile sensitivity in blind people compared with sighted people. The tactile task like discrimination, recognition, shape and size are more superior in visually challenged than compared to normal sighted subjects. The present study demonstrates that the primary submodalities of somatic sensations (touch, pain, temperature and vibratory sense) in visually challenged are similar to those of sighted person
