We conducted a functional assessment of problem behaviors of 2 students with developmental disabilities in their classroom environments. Results of the assessments showed that although there were more tantrums in demand than in no-demand conditions, the function of the behavior was to gain attention (positive reinforcement) rather than to avoid or escape demands (negative reinforcement); demand conditions apparently served a discriminative function for the availability of attention. Therefore, intervention was based on the positive reinforcement hypothesis, resulting in a substantial reduction of tantrums for both subjects.
我们对两名发育障碍学生在课堂环境中的问题行为进行了功能评估。评估结果表明,尽管在有要求的情况下发脾气的次数比无要求的情况下更多,但行为的功能是获得关注(正强化)而非避免或逃避要求(负强化);有要求的情况显然对获得关注起到了辨别作用。因此,干预基于正强化假设,两名受试者的发脾气行为都大幅减少。
