How can a task-appropriate response be selected for an ambiguous target stimulus in task-switching situations? One answer is to use compound cue retrieval, whereby stimuli serve as joint retrieval cues to select a response from long-term memory. In the present study, the authors tested how well a model of compound cue retrieval could account for a complex pattern of congruency effects arising from a procedure in which a cue, prime, and target were presented on each trial. A comparison of alternative models of prime-based effects revealed that the best model was one in which all stimuli participated directly in the process of retrieving a response, validating previous modeling efforts. Relations to current theorizing about response congruency effects and models of response selection in task switching are discussed.
在任务切换情境中,如何为模糊的目标刺激选择适合任务的反应?一种答案是使用复合线索检索,即刺激作为联合检索线索,从长期记忆中选择一种反应。在本研究中,作者测试了复合线索检索模型能够在多大程度上解释由每次试验呈现一个线索、启动刺激和目标刺激的程序所产生的复杂的一致性效应模式。对基于启动刺激效应的替代模型的比较表明,最佳模型是所有刺激都直接参与反应检索过程的模型,这验证了之前的建模工作。文中还讨论了与当前关于反应一致性效应的理论以及任务切换中反应选择模型的关系。
