The study aims to verify the differences in Kinesthetic tactile estimations among blind, deaf and normal. The study's sample consists of two main groups: the experimental group and the controlling group. The experimental groups were of (60) sensory handicapped participants (30) are early blind people who are divided into (20) secondary staged blind students at Al-Nour School in Benha, and (10) blind students at the Faculty of Arts, Benha University. The other (30) participants are early deaf students in the technical secondary stage at Al-Amal School for the Deaf and Hard of Hearing in Benha, and the schools belonging to the Educational Administration for Special Education in Benha, Al Qalyubia Governorate. These students are aged between (16-21) years. The second main controlling group consists of (30) normal participants, divided into (15) students selected from the Qalyubia National Bank Secondary School in Benha, and (15) students from the Faculty of Arts, Benha University. These students are homogenized not only in blindness and deafness, but also in age, educational level, intelligence, and preferred hand. Tools of the study: An initial interview for the blind, the deaf and the normal to collect primary data concerning the economic, social and cultural level scale, the preferred hand, the Stanford-Binet intelligence scale (fifth image), and the weight discrimination device. The study has shown that differences in the kinesthetic tactile estimates between the blind, the deaf, and the normal go in the direction of the blind, followed by the normal, and finally the deaf.
