A behaviour modification programme for a child with multiple problem behaviours.

The report described a series of behaviour modification programmes for altering hyperaggressive, fearful, negativistic behaviours in a 5-year-old child who had been rejected by his peer group. The parents, teachers, peer group and the experimenters served as treatment agents. One programme counter conditioned the fear reactions; a "time out" procedure was used to alter the assaultive behaviour, and an operant conditioning technique was used to increase co-operative behaviours. Finally, a conditioning programme was initiated which altered the interaction between child and his peers. Observation data were collected prior to, during, and following the experimental programme to provide a basis for evaluating the outcomes.
