A review and evaluation of research on the deaf-blind from perceptual, communicative, social and rehabilitative perspectives

Abstract

This paper reviews research on deaf-blind individuals, primarily from behavioral and communicative points of view. Inclusion in the population of deaf-blind is qualified by describing a variety of subgroups and genetically based syndromes associated with deafblindness. Sensory assessment procedures - based primarily on residual capacities - are appraised. Consequences for everyday life are described briefly. Non-sensory, alternative classificatory schemes and procedures are presented and the results from behavior modification procedures used for correcting maladaptive behaviors are summarized. Methods for communicating tactilely are described and evaluated. Attention is also drawn to some suggestions regarding learning of alphabetic codes and sign acquisition. Finally, suggestions for future research are proposed.
