We investigated stimulus-response (S-R) memory links during object priming using a binary associative size judgement paradigm. At study, participants decided which of two objects was bigger in real life and, at test, made the same or the reverse judgement. We examined the effects of response congruence on item S-R priming in the associative paradigm. In Experiment 1, a task reversal manipulation had minimal impact on RT priming when classifications were congruent for both recombined objects between study and test. Experiment 2 found that RT priming was more disrupted by classification incongruence of the selected than of the nonselected item alone, with incongruence of the nonselected object having no effect on RTs. Experiment 3, however, found that classification incongruence of both items eliminated RT priming, indicating that a significant effect of classification incongruence for the nonselected item is only evident if both items are classification-incongruent. Finally, across all experiments, we found that accuracy was more sensitive than RTs to decision/action incongruence. We interpret these findings in light of a two-stream account of S-R priming, and suggest a few extensions to account for interactions between S-R links of recombined items.
我们使用二元关联大小判断范式，研究了物体启动过程中的刺激-反应（S-R）记忆联系。在学习阶段，参与者判断两个物体在现实生活中哪个更大，在测试阶段，做出相同或相反的判断。我们研究了反应一致性对关联范式中项目S-R启动的影响。在实验1中，当学习和测试中两个重组物体的分类一致时，任务反转操作对反应时启动的影响最小。实验2发现，与仅非选择项目的分类不一致相比，选择项目的分类不一致对反应时启动的干扰更大，非选择物体的不一致对反应时没有影响。然而，实验3发现，两个项目的分类不一致消除了反应时启动，这表明只有当两个项目都存在分类不一致时，非选择项目的分类不一致才会产生显著影响。最后，在所有实验中，我们发现准确性比反应时对决策/行动不一致更敏感。我们根据S-R启动的双流理论来解释这些发现，并提出一些扩展来解释重组项目的S-R联系之间的相互作用。
