本研究旨在考察不同通道对任务转换的影响。为此，参与者在通道相容任务(听觉-发声和视觉-手动)或不相容的空间辨别任务(听觉-手动和视觉-发声)之间切换。此外，在每个实验中，听觉和视觉刺激被同时呈现(即，双峰)，因此需要选择性注意来处理与任务相关的刺激。双峰刺激的加入使我们能够评估一致性效应，将其作为任务间干扰增加的汇聚性测量。这些任务遵循预先指示的双交替序列(AABB)，因此不需要明确的任务线索。结果表明，与在两个通道相容任务之间的转换相比，在两个通道不相容任务之间的转换增加了转换成本和一致性效应。在通道不相容的任务中，一致性效应增加的发现支持了我们的解释，即预期反应效应与最初要求这种反应的刺激之间的观念运动“后向”联系。根据这一广义的理想运动概念，反应效果和刺激之间的通道匹配将启动对相容通道中的反应的选择。这种启动将导致忽略竞争刺激的难度增加，从而增加一致性效应。此外，当在通道不兼容的任务之间切换时，性能会受到阻碍，而在通道兼容的任务之间切换时，性能会受到促进。
The present study was aimed at examining modality-specific influences in task switching. To this end, participants switched either between modality compatible tasks (auditory–vocal and visual–manual) or incompatible spatial discrimination tasks (auditory–manual and visual–vocal). In addition, auditory and visual stimuli were presented simultaneously (i.e., bimodally) in each trial, so that selective attention was required to process the task-relevant stimulus. The inclusion of bimodal stimuli enabled us to assess congruence effects as a converging measure of increased between-task interference. The tasks followed a pre-instructed sequence of double alternations (AABB), so that no explicit task cues were required. The results show that switching between two modality incompatible tasks increases both switch costs and congruence effects compared to switching between two modality compatible tasks. The finding of increased congruence effects in modality incompatible tasks supports our explanation in terms of ideomotor “backward” linkages between anticipated response effects and the stimuli that called for this response in the first place. According to this generalized ideomotor idea, the modality match between response effects and stimuli would prime selection of a response in the compatible modality. This priming would cause increased difficulties to ignore the competing stimulus and hence increases the congruence effect. Moreover, performance would be hindered when switching between modality incompatible tasks and facilitated when switching between modality compatible tasks.
