摘要在本研究中，我们探讨了认知控制灵活性的通道特异性。我们比较了单一任务和混合任务区块中听觉和视觉刺激区块的表现，以评估交替成本(单一任务和混合任务)。混合区块仅由任务切换组成。这些任务包括数字奇偶性、大小和距离判断，判断范围是1到9之间的数字，而不是5。一个提示指示了相关的任务。不同的线索-刺激间隔(短间隔和长间隔)来检查准备效果。结果表明，与单一任务相比，混合任务组的反应时间(RTS)和错误率(ER)更高。与视觉刺激呈现相比，听觉呈现的ERS的交替成本更大。此外，与视觉通道相比，基于准备时间增加的RT替代成本的减少在听觉通道中更为明显。这些结果表明，在维持和更新工作记忆中的任务集的过程中，存在通道特有的影响。
ABSTRACT In the current study, we addressed modality-specificity of the flexibility of cognitive control. We compared performance in single-task and mixed-tasks blocks between blocked auditory and visual stimuli assessing alternation costs (single vs. mixed). Mixed blocks comprised task switches only. The tasks consisted of numerical parity, magnitude, and distance judgments about numbers between one and nine without five. A cue indicated the relevant task. The cue–stimulus interval was varied (short vs. long interval) to examine preparation effects. The results indicated higher response times (RTs) and error rates (ERs) in mixed- vs. single-tasks blocks. The alternation costs in ERs were larger for auditory compared to visual stimulus presentation. Moreover, the reduction of RT alternation costs based on increased preparation time was more pronounced for the auditory modality compared to the visual modality. These results suggest a modality-specific influence on processes involved in maintaining and updating task sets in working memory.
