The pairings of tasks' stimulus and response modalities affect the magnitude of dual-task costs. For example, dual-task costs are larger when a visual-vocal task is paired with an auditory-manual task compared with when a visual-manual task is paired with an auditory-vocal task. These results are often interpreted as reflecting increased crosstalk between central codes for each task. Here we examine a potential source: modality-based crosstalk between the stimuli and the response-induced sensory consequences (i.e., action effects). In five experiments, we manipulated experimentally induced action effects so that they were either modality-compatible or -incompatible with the stimuli. Action effects that were modality-compatible (e.g., visual stimulus, visual action effect) produced smaller dual-task costs than those that were modality-incompatible (e.g., visual stimulus, auditory action effect). Thus, the relationship between stimuli and action effects contributes to dual-task costs. Moreover, modality-compatible pairs showed an advantage compared with when no action effects were experimentally induced. These results add to a growing body of work demonstrating that postresponse sensory events affect response selection processes. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

提示效果：刺激-行动效果模态兼容性和双任务成本。


任务的刺激和响应模式的配对会影响双重任务成本的大小。例如，与视觉-手动任务与听觉-声音任务配对时相比，当视觉-声音任务与听觉-手动任务配对时，双任务成本更大。这些结果通常被解释为反映了每个任务的中央代码之间的串扰增加。在这里，我们检查一个潜在的来源：刺激和反应引起的感官后果（即动作效果）之间基于模态的串扰。在五个实验中，我们操纵了实验诱导的动作效应，使它们与刺激模态兼容或不兼容。模态兼容的动作效果（例如，视觉刺激、视觉动作效果）比那些模态不兼容的动作效果（例如，视觉刺激、听觉动作效果）产生更小的双任务成本。因此，刺激和行动效果之间的关系会影响双重任务成本。此外，与没有实验诱导作用效应时相比，模态兼容对显示出优势。这些结果增加了越来越多的工作，表明反应后感觉事件影响反应选择过程。 （PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
