Twelve college students received conditional discrimination training with nonarbitrary and arbitrary stimuli, and derived comparative and transformation of function tests with a think-aloud condition across 2 experiments. Participants who failed these tests received remedial verbal operant training. Four control participants received verbal operant training alone. Across both experiments, only 1 participant passed the derived comparative test after conditional discrimination training. However, all participants passed derived comparative tests and 11 out of 12 participants passed transformation of function tests following verbal operant training, including the 4 control participants. Participants who passed derived comparative tests engaged in a high percentage of correct vocalizations during the think-aloud condition, while participants who failed did not. These results suggest that mediating verbal behavior could have played a crucial role in participants' responses during derived stimulus relations tests.
十二名大学生接受了非任意和任意刺激的条件辨别训练，并在两个实验中通过出声思维条件进行了功能转化和比较测试。未能通过这些测试的参与者接受了补救性言语操作性训练。四名对照组参与者仅接受了言语操作性训练。在两个实验中，只有 1 名参与者在条件辨别训练后通过了衍生比较测试。然而，所有参与者都通过了衍生比较测试，12 名参与者中有 11 名通过了功能转化测试，包括 4 名对照组参与者。通过衍生比较测试的参与者在出声思维条件下表现出较高比例的正确发声，而未通过测试的参与者则没有。这些结果表明，中介言语行为可能在参与者在衍生刺激关系测试中的反应中起到了关键作用。
