Use of Black Light in Training Retarded, Multiply Handicapped, Deaf-Blind Children

One group of severely or profoundly retarded, multiply handicapped, deaf-blind children were given a training program using a black light environment which allowed for the removal of all distracting stimuli and for exaggeration of the critical features from which the children learn. Another group was given training under normal light. The children trained under black light performed the task they had been taught significantly better than the children trained under normal light.
