在三个实验中，我们测量了反应时间（RT）和峰值力（PF），调查分组的左，右手按键反应的双任务范式，涉及两个独立的去/不去的任务。在每个任务中，两种模态之一内的go刺激（即，视觉与听觉）需要单手做出反应。在实验1中，同时去刺激的两个任务，反应似乎被分组在大约75-80%的试验，相比之下，近100%的分组在一个单一的任务条件下，需要双手反应的任何刺激的发作在任何一种方式。在实验2中，两个go刺激之间的刺激起始时间（SOA）为0-400 ms，响应分组明显下降SOA增加，虽然一些分组仍然是明显的，即使在最长的SOA。在实验3中观察到相同的模式，具有相同的SOA范围，但不可预测的刺激顺序，这表明分组并不强烈依赖于先验知识的可能的响应顺序。这些结果强调了双手双任务RT范式中反应分组的普遍性，并提供了有用的线索，其性质。
In three experiments we measured response time (RT) and peak force (PF) to investigate the grouping of left- and right-hand key press responses in a dual-task paradigm involving two independent go/no-go tasks. Within each task, a go stimulus within one of two modalities (i.e., visual versus auditory) required a response by one hand. In Experiment 1 with simultaneous go stimuli in the two tasks, responses appeared to be grouped in approximately 75–80% of trials, compared with nearly 100% grouping in a single-task condition requiring bimanual responses to the onset of any stimulus in either modality. In Experiment 2 with stimulus onset asynchronies (SOAs) of 0–400 ms between the two go stimuli, response grouping clearly declined as SOA increased, although some grouping was still evident even at the longest SOA. The same pattern was observed in Experiment 3 with the same range of SOAs but unpredictable stimulus order, suggesting that grouping is not strongly dependent on prior knowledge of the likely response order. These results emphasize the pervasiveness of response grouping in bimanual dual-task RT paradigms and provide useful clues as to its nature.
