Trainable mentally retarded adolescents were taught personal hygiene under two conditions. One group was given instruction by demonstration; the second group received the same demonstration plus filmstrip viewing. Changes in hygienic self help were measured by the teacher's and mother's ratings of behavior. The use of filmstrip increased learning in several areas of hygiene, and particularly appeared to improve generalization of newly learned habits from the classroom to the home.
Thompson et al. (Thu,) studied this question.
