Abstract

Action selection is thought to involve selection of the action's sensory outcomes. This notion is supported when encountering a distractor that resembles a learned response-outcome biases response selection. Some evidence, however, suggests that a larger contribution of stimulus-based response selection leaves little role for outcome-based selection, especially in forced-choice tasks with easily identifiable target stimuli. In the present study, we asked whether the contribution of outcome-based selection depends on the ease and efficiency of stimulus-based selection. If so, then efficient stimulus-based response selection should reduce the impact of an irrelevant distractor that resemble a response-outcome. We manipulated efficiency of stimulus-based selection by varying the spatial relationship between stimulus and response (Experiment 1) and by varying stimulus discriminability (Experiments 2). We hypothesized that with efficient stimulus-based selection, outcome-based processes will play a weaker role in response selection, and performance will be less susceptible to outcome-compatible or -incompatible distractors. By contrast, when stimulus-based selection is relatively inefficient, outcome-based processes will play a stronger role in response selection, and performance should be more susceptible to outcome-compatible or -incompatible distractors. Confirming our predictions, our results showed stronger impact of the distractors when stimulus-based response selection was relatively inefficient. Finally, results of a control experiment (Experiment 3) suggested that learning the consistent response-outcome mapping is necessary for obtaining the effect of these distractors. We conclude that outcome-based processes do contribute to response selection in forced-choice tasks, and that this contribution varies with the efficiency of stimulus-based response selection.

摘要

动作选择被认为涉及对动作的感觉结果的选择。当遇到一个类似于习得的反应-结果的干扰物时,这种观点得到了支持,它会使反应选择产生偏差。然而,一些证据表明,基于刺激的反应选择的更大作用使得基于结果的选择几乎没有作用,尤其是在具有易于识别的目标刺激的强制选择任务中。在本研究中,我们探讨了基于结果的选择的作用是否取决于基于刺激的选择的难易程度和效率。如果是这样,那么高效的基于刺激的反应选择应该会减少类似于反应-结果的无关干扰物的影响。我们通过改变刺激与反应之间的空间关系(实验1)以及改变刺激的可辨别性(实验2)来操纵基于刺激的选择的效率。我们假设,在高效的基于刺激的选择下,基于结果的过程在反应选择中所起的作用会较弱,并且表现将不太容易受到与结果相符或不符的干扰物的影响。相比之下,当基于刺激的选择相对低效时,基于结果的过程在反应选择中所起的作用会更强,并且表现应该更容易受到与结果相符或不符的干扰物的影响。我们的结果证实了我们的预测,即当基于刺激的反应选择相对低效时,干扰物的影响更强。最后,一个控制实验(实验3)的结果表明,学习一致的反应-结果映射对于获得这些干扰物的效果是必要的。我们得出结论,基于结果的过程确实对强制选择任务中的反应选择有贡献,并且这种贡献会随着基于刺激的反应选择的效率而变化。(PsycINFO数据库记录)
