采用挫折感（拉杠杆的速度/强度）和注意力（对光信号的反应时）测量方法，研究了奖励时间表（100%、50%和30%）和奖励终止（消退）对30名注意缺陷多动障碍（ADD-H）儿童和30名正常儿童的影响。ADD-H在灭绝期间和最低（30%）部分时间表上比对照组更努力地拉动杠杆，提供了经验证据表明，当预期的奖励没有出现时，他们比正常人更沮丧。两组在100%奖励的注意力测量上没有差异。然而，部分时间表似乎有一个警示或激励效果的控制，使他们的反应更快，更一致的ADD-H的部分时间表。调查结果进行了讨论，参考对立的理论，关于性质的异常反应的ADD-H奖励
The effects of reward schedule (100%, 50%, and 30%) and termination of rewards (extinction) on 30 attention deficit disorder with hyperactivity (ADD-H) and 30 normal children were studied using measures of frustration (speed/strength of lever pulling) and attention (reaction time to a light signal). ADD-Hs pulled harder on the lever than controls during extinction and on the lowest (30%) partial schedule, providing empirical evidence that they respond with greater frustration than normals when expected rewards fail to appear. The groups did not differ on the attentional measure on 100% reward. However, the partial schedules appeared to have an alerting or motivating effect on the controls, so that they responded more quickly and consistently than ADD-Hs on the partial schedules. Findings are discussed with reference to opposing theories regarding the nature of the abnormal response of ADD-Hs to reward
