In Experiment 1, more and less relations were trained for arbitrary Stimuli A1 and A2 with 3 children with autism. The following conditional discriminations were then trained: A1-B1, A2-B2, B1-C1, B2-C2. In subsequent tests, participants showed derived more-less mands (mand with C1 for more and mand with C2 for less). A training procedure reversed the B-C conditional discriminations, and participants then showed derived reversed more-less mands (mand with C1 for less, C2 for more). Baseline B-C relations were retrained, and participants subsequently demonstrated a return to the original derived manding. A second experiment with 1 prior participant and 1 naive participant removed a possible confounding effect. Establishing derived manding may be an advantageous component when teaching a mand repertoire in applied settings.
在实验 1 中,我们对 3 名自闭症儿童进行了任意刺激 A1 和 A2 的多-少关系训练。随后,我们对以下条件辨别进行了训练:A1-B1、A2-B2、B1-C1、B2-C2。在随后的测试中,参与者表现出了衍生的多-少需求(C1 代表多,C2 代表少)。训练程序反转了 B-C 条件辨别,参与者随后表现出了反转的多-少需求(C1 代表少,C2 代表多)。我们重新训练了基线 B-C 关系,随后参与者表现出了回归到原始衍生的需求。第二个实验有 1 名先前参与者和 1 名新手参与者,排除了可能的混杂效应。在应用环境中教授需求词汇表时,衍生的需求可能是一个有利的组成部分。
