The case study reports the findings of systematic play training with a 7 year old autistic male who had never exhibited play behavior. The research procedure involved three phases: imitation training, training manipulative play, and motivation training. Training during the three phases was conducted three times per week for 7 1/2 months in a quiet area of the self contained public school classroom. Results supported the contention that play behavior can be trained. On immediate posttest the child could perform 100% of the imitations--77% on verbal command and 23% with a model. Training manipulative play with six toys was achieved. The child decreased the frequency of socially unacceptable behaviors and increased the frequency of socially acceptable play behaviors.
