The experiment determined whether equivalence class formation required overlap of comparison stimuli and responding. Each trial contained a sample first, a single, nonoverlapping comparison second, and a nonoverlapping response‐window (RW) third, during which the participant made one of two responses (2R). All 11 participants formed two 3‐member ABC equivalence classes using these “trace‐stimulus‐pairing two‐response with response window” (TSP‐2R‐RW) trials. After adding a fourth stimulus (D) by CD training, ABCD tests showed immediate expansion to 4‐member ABCD classes. When 4‐member probes (AD, DA, BD, DB, CD, DC) were administered without 3‐member probes, many participants showed decrements in class‐indicative responding that then resurged to mastery with test repetition. Thus, 3‐member probes enhanced class expansion. Class formation occurred for all participants when responding was temporally dissociated from the comparisons. In a matched, contemporaneously published experiment, where responding occurred during comparisons, only 54% of participants formed the classes. Thus, the comparison‐response‐separation nearly doubled class formation. Additionally, a special post‐class‐formation sorting test documented the emergence of two explicit equivalence classes. Finally, we noted a 1:1 correspondence for TSP‐2R‐RW and priming trials. Since priming measures neural substrates of equivalence classes, TSP‐2R‐RW trials should do the same.

从样本和比较刺激中分离出响应时的等效类形成:工作记忆,启动和排序

实验确定等效类的形成是否需要比较刺激和响应的重叠。每个试验首先包含一个样本,其次是一个不重叠的比较,然后是不重叠的响应窗口(RW),在此期间,参与者做出了两个响应(2R)中的一个。所有11名参与者都使用这些“具有响应窗口的跟踪-刺激-配对两个响应”(TSP-2R-RW)试验形成了两个3成员ABC等价类。通过CD训练增加了第四个刺激(D)之后,ABCD测试显示立即扩展到4成员ABCD类。如果在不使用3成员探针的情况下使用4成员探针(AD,DA,BD,DB,CD,DC),则许多参与者显示出类指示响应的减少,然后又通过测试重复而精通。因此,三成员探针增强了类扩展。当响应时间与比较时间无关时,所有参与者的班级形成都会发生。在一个匹配的,同时发布的实验中,在比较过程中出现了响应,只有54%的参与者组成了课程。因此,比较-响应-分离几乎使班级形成加倍。此外,一个特殊的类后形成排序测试记录了两个显式对等类的出现。最后,我们注意到了TSP-2R-RW和启动试验的1:1对应关系。由于启动可测量等效类的神经底物,因此TSP-2R-RW试验也应这样做。比较-反应-分离几乎使班级人数增加了一倍。此外,一个特殊的类后形成排序测试记录了两个显式对等类的出现。最后,我们注意到了TSP-2R-RW和启动试验的1:1对应关系。由于启动可测量等效类的神经底物,因此TSP-2R-RW试验也应这样做。比较-反应-分离几乎使班级人数增加了一倍。此外,一个特殊的类后形成排序测试记录了两个显式对等类的出现。最后,我们注意到了TSP-2R-RW和启动试验的1:1对应关系。由于启动可测量等效类的神经底物,因此TSP-2R-RW试验也应这样做。
