The present experiment examined the effect of having the D-stimuli as meaningful pictures when establishing 18 conditional discriminations and testing for the emergence of three 7-member equivalence classes (A→B→C→D→E→F→G). Twenty participants were randomly assigned to two main experimental groups. In one group, the participants were exposed to training and testing with abstract stimuli only (the ABS group). In the other group, the participants were exposed to D-stimuli as meaningful pictures and the A, B, C, E, F, and G stimuli as abstract stimuli (the PIC group). If the participants in the PIC group did not form equivalence classes, they repeated the experiment in a new condition (DA-as-PIC) that had a new stimulus set different from the PIC group where the D and A stimuli are meaningful stimuli whereas the B, C, E, F, and G stimuli were abstract stimuli. The participants who did not form equivalence classes in the DA-as-PIC condition repeated the experiment in a new condition (DAG-as-PIC) that had a new stimulus set different from the PIC and DA-as-PIC where the D, A, and G stimuli are meaningful stimuli whereas the B, C, E, and F stimuli were abstract. The main findings from the experiment showed that 1 of 10 participants in the ABS group formed equivalence classes, whereas 5 of 10 participants in the PIC group formed equivalence classes. Furthermore, the result showed that three of the five participants who did not form equivalence classes in the PIC group formed classes in the DA-as-PIC condition. Finally, two of the five participants who did not form equivalence classes in the DA-as-PIC condition formed classes in the DAG-as-PIC condition.

有意义的刺激在大型刺激类中的作用

本实验检验了在建立 18 个条件判别和测试三个 7 成员等价类(A→B→C→D→E→F→G)出现时将 D 刺激作为有意义的图片的效果。二十名参与者被随机分配到两个主要的实验组。在一组中,参与者仅接受抽象刺激的训练和测试(ABS 组)。在另一组中,参与者将 D 刺激作为有意义的图片,将 A、B、C、E、F 和 G 刺激作为抽象刺激(PIC 组)。如果 PIC 组的参与者没有形成等价类,他们在新条件(DA-as-PIC)中重复实验,该条件具有不同于 PIC 组的新刺激集,其中 D 和 A 刺激是有意义的刺激,而B、C、E、F、G 刺激是抽象刺激。未在 DA-as-PIC 条件下形成等价类的参与者在新条件 (DAG-as-PIC) 中重复实验,该条件具有不同于 PIC 和 DA-as-PIC 的新刺激集,其中 D, A 和 G 刺激是有意义的刺激,而 B、C、E 和 F 刺激是抽象的。实验的主要发现表明,ABS 组的 10 名参与者中有 1 名形成了等价类,而 PIC 组的 10 名参与者中有 5 名形成了等价类。此外,结果表明,在 PIC 组中没有形成等价类的五名参与者中有三人在 DA-as-PIC 条件下形成了类。最后,没有在 DA-as-PIC 条件下形成等价类的五个参与者中的两个在 DAG-as-PIC 条件下形成了类。未在 DA-as-PIC 条件下形成等价类的参与者在新条件 (DAG-as-PIC) 中重复实验,该条件具有不同于 PIC 和 DA-as-PIC 的新刺激集,其中 D, A 和 G 刺激是有意义的刺激,而 B、C、E 和 F 刺激是抽象的。实验的主要发现表明,ABS 组的 10 名参与者中有 1 名形成了等价类,而 PIC 组的 10 名参与者中有 5 名形成了等价类。此外,结果表明,在 PIC 组中没有形成等价类的 5 名参与者中有 3 人在 DA-as-PIC 条件下形成了类。最后,没有在 DA-as-PIC 条件下形成等价类的五个参与者中的两个在 DAG-as-PIC 条件下形成了类。未在 DA-as-PIC 条件下形成等价类的参与者在新条件 (DAG-as-PIC) 中重复实验,该条件具有不同于 PIC 和 DA-as-PIC 的新刺激集,其中 D, A 和 G 刺激是有意义的刺激,而 B、C、E 和 F 刺激是抽象的。实验的主要发现表明,ABS 组的 10 名参与者中有 1 名形成了等价类,而 PIC 组的 10 名参与者中有 5 名形成了等价类。此外,结果表明,在 PIC 组中没有形成等价类的五名参与者中有三人在 DA-as-PIC 条件下形成了类。最后,没有在 DA-as-PIC 条件下形成等价类的五个参与者中的两个在 DAG-as-PIC 条件下形成了类。
