Six subjects, comprising one class at a school for the deaf, were given reinforcement consisting of time free from school work for remaining seated in the classroom. As a result, the frequency of leaving their chairs was sharply reduced. A second procedure presented free-time not contingent on remaining seated. Little change was seen in the already lowered response rate. An extension of the time required to be seated with corresponding reduction in the number of daily free-time periods did not reduce the effectiveness of the procedure. A one-day observation after six weeks indicated that the procedure was still effective. A one-day contingency reversal, requiring subjects to leave their chairs at least once during each seated period in order to receive free-time, substantially raised the frequency of out-of-seat responses.
六名被试者，包括一所聋人学校的一个班级，得到了强化，即不用上课而留在教室里就可以获得自由时间。结果，他们离开椅子的频率大大降低了。第二种方法提供的自由时间不是取决于是否坐着。已经降低的反应率几乎没有变化。延长坐着的时间，相应减少每天自由时间的次数，并没有降低该程序的效果。六周后进行了一天的观察，表明该程序仍然有效。一天的应急反转，要求被试者在每次坐着的时间内至少离开椅子一次才能获得自由时间，这大大提高了离开座位的频率。
