Sensory-motor modality compatibility is defined as the similarity between the sensory modality and the modality of response-related effects. Previous dual-task and task-switching studies have shown higher performance costs for coordinating relatively incompatible sensory-motor modality mappings (i.e., auditory-manual and visual-vocal) compared to more compatible mappings (i.e., auditory-vocal and visual-manual). Until now, however, little attention has been paid to potential variability in effects of modality compatibility depending on different processing codes. In the present study, we independently varied the processing codes of input and output (nonverbal-spatial, nonverbal-nominal, verbal-spatial, verbal-nominal) while participants switched between incompatible and compatible sensory-motor modality mappings. Beside higher switch costs for switching between incompatible sensory-motor modality mappings than for switching between compatible mappings, the results revealed stronger effects of modality compatibility on switch costs for verbal input than for nonverbal input codes. This suggests that priming mechanisms between sensory input and compatible motor output are modulated by the processing code of the sensory input. As possible explanations, we assume a higher degree of concordance with output processing codes as well as stronger associations with potential response effects for verbal than for nonverbal input.
感觉运动模态兼容性被定义为感觉模态与反应相关效应的模态之间的相似性。先前的双任务和任务切换研究表明，与更兼容的映射（即听觉-发声和视觉-手动）相比，协调相对不兼容的感觉运动模态映射（即听觉-手动和视觉-发声）时，执行成本更高。然而，到目前为止，很少有人关注模态兼容性效应因不同处理代码而产生的潜在变异性。在本研究中，我们在参与者在不兼容和兼容的感觉运动模态映射之间切换时，独立地改变输入和输出的处理代码（非语言-空间、非语言-名义、语言-空间、语言-名义）。除了在不兼容的感觉运动模态映射之间切换比在兼容映射之间切换有更高的切换成本外，结果还显示，与非语言输入代码相比，模态兼容性对语言输入的切换成本影响更强。这表明感觉输入与兼容运动输出之间的启动机制受感觉输入的处理代码调节。作为可能的解释，我们假设与输出处理代码的一致性程度更高，以及与语言输入相比，非语言输入与潜在反应效应的关联更强。
