In a two-phase experiment, four different token conditions were presented each session to retarded students in a TMR class. In Phase 1, students responded by matching-to-sample under the following conditions: (A) correct responses produced exchangeable tokens, (B) correct responses produced exchangeable tokens and incorrect responses lost tokens, (C) correct responses produced nonexchangeable tokens, and (D) no-tokens given. In Phase 2, the students chose the condition in which they worked. Results showed that responses cost decreased errors but did not influence correct responding, that each baseline condition produced less correct responding than the token conditions, and that Condition C produced more responding than D. Phase 2 results showed a preference for Condition A and no difference between Conditions B and C. Results were discussed in terms of baselines, response cost, and type of datum.
在一项两阶段实验中，每次课都向一个重度智障学生班级的学生呈现四种不同的代币条件。在第一阶段，学生在以下条件下通过匹配样本进行反应：(A) 正确反应产生可交换代币；(B) 正确反应产生可交换代币，错误反应失去代币；(C) 正确反应产生不可交换代币；(D) 不给予代币。在第二阶段，学生选择他们进行操作的条件。结果表明，反应代价减少了错误，但不影响正确反应；每个基线条件下的正确反应都比代币条件下少；条件C比条件D产生的反应更多。第二阶段的结果表明，学生偏爱条件A，条件B和C之间没有差异。根据基线、反应代价和数据类型对结果进行了讨论。
