This study explored the role of baseline reject control on transitivity responding. In Experiment 1, participants learned to respond to a baseline of arbitrary AB and AC conditional relations, and then they were exposed to transitivity-like BC and CB trials in which the correct comparison stimulus was replaced by a novel stimulus (D). Five of 10 participants selected stimulus D, but only 1 showed expansion of the baseline stimulus classes to include the D stimuli. In Experiment 2, the emergence of symmetry and transitivity from baseline relations was assessed before participants were exposed to the transitivity-like trials. Six of 8 participants who showed emergence of equivalence relations selected the D stimuli on transitivity-like trials and provided evidence that baseline classes expanded to include these stimuli. In Experiment 3, these 6 participants selected novel stimuli (E) in additional transitivity-like trials, and all showed that the E stimuli had become members of the previously established classes, which now comprised 5 members. A route for the emergence of transitivity by way of the transfer of baseline between-classes reject control is discussed.
本研究探讨了基线拒绝控制在及物性反应中的作用。在实验 1 中，参与者学习对任意 AB 和 AC 条件关系的基线做出反应，然后他们接触到类似 transitivity 的 BC 和 CB 试验，其中正确的比较刺激物被替换为新的刺激物（D）。在 10 名参与者中有 5 名选择了刺激物 D，但只有 1 名参与者将基线刺激类扩展到包括 D 刺激物。在实验 2 中，在参与者接触类似 transitivity 的试验之前，评估了从基线关系中出现的对称性和 transitivity。在 8 名表现出等价关系出现的参与者中有 6 名在类似 transitivity 的试验中选择了 D 刺激物，并提供了证据表明基线类扩展到包括这些刺激物。在实验 3 中，这 6 名参与者在额外的类似 transitivity 的试验中选择了新的刺激物（E），并且都表明 E 刺激物已经成为先前建立的类的成员，现在包含 5 个成员。讨论了通过在类间基线拒绝控制之间转移来出现 transitivity 的途径。
