"'An excellent book... of great practical value to parents and professionals. Its value lies not in the exhaustive repetition of other literature, but in its logical, developmental approach. It makes sense of the predicament a ""deaf-blind"" or multi-sensory deprived child finds himself in, with distortions in perception that inevitably lead to deviant behaviour that can all too easily be mislabelled as constituting mental retardation, brain damage, or psychiatric disorder. The absolute necessity of modifying and patterning input, rather than relying on incidental learning, is made crystal clear.' --Dr. Roger D. Freeman, Director of Services for Handicapped Children, Division of Child Psychiatry, University of British Columbia."
