Discrete task-relevant features of an overt response, such as response location, are bound to, and retrieved by coincidentally occurring auditory stimuli. Here we studied whether continuous, task-irrelevant response features like force or response duration also become bound to, and retrieved by such stimuli. In two experiments we asked participants to carry out a pinch which produced a certain auditory effect in a prime part of each trial. In a subsequent probe part, tones served as imperative stimuli which either repeated or changed as compared to the effect tone in the prime. We conjectured that the repetition of tones should result in more similar responses in terms of force output and duration as compared to tone changes. Most parameters did not show notable indications for such similarity increases, including peak force or area under force curve, though the correlation between response durations in prime and probe was higher when tones repeated rather than changed from prime to probe. We discuss these results regarding perceptual discriminability and deployment of attention to different nominally task-irrelevant aspects of pinch responses.
明显反应的离散任务相关特征，如反应位置，会与同时出现的听觉刺激绑定，并通过这些刺激进行检索。在这里，我们研究了诸如力量或反应持续时间等连续的、与任务无关的反应特征是否也会与此类刺激绑定并通过其检索。在两个实验中，我们要求参与者进行捏合动作，在每个试验的主要部分会产生特定的听觉效果。在随后的探测部分，与主要部分的效果音相比，音调作为指令刺激，要么重复，要么改变。我们推测，与音调变化相比，音调重复应会导致在力量输出和持续时间方面产生更相似的反应。大多数参数没有显示出这种相似性增加的显著迹象，包括峰值力量或力量曲线下的面积，不过当音调重复而非从主要部分变化到探测部分时，主要部分和探测部分的反应持续时间之间的相关性更高。我们讨论了这些关于感知辨别力以及对捏合反应不同名义上与任务无关方面的注意力分配的结果。
