This study investigated whether the visual and auditory Simon effects could be accounted for by the same mechanism. In a single experiment, we performed a detailed comparison of the visual and the auditory Simon effects arising in behavioural responses and in pupil dilation, a psychophysiological measure considered as a marker of the cognitive effort induced by conflict processing. To address our question, we performed sequential and distributional analyses on both reaction times and pupil dilation. Results confirmed that the mechanisms underlying the visual and auditory Simon effects are functionally equivalent in terms of the interaction between unconditional and conditional response processes. The two modalities, however, differ with respect to the strength of their activation and inhibition. Importantly, pupillary data mirrored the pattern observed in behavioural data for both tasks, adding physiological evidence to the current literature on the processing of visual and auditory information in a conflict task.
本研究调查了视觉和听觉西蒙效应是否可由相同机制解释。在一项单一实验中，我们对行为反应和瞳孔扩张中出现的视觉和听觉西蒙效应进行了详细比较，瞳孔扩张是一种心理生理测量指标，被视为冲突处理所诱发认知努力的标志。为解决我们的问题，我们对反应时间和瞳孔扩张进行了序列分析和分布分析。结果证实，就无条件和条件反应过程之间的相互作用而言，视觉和听觉西蒙效应背后的机制在功能上是等效的。然而，这两种模式在激活和抑制强度方面存在差异。重要的是，瞳孔数据反映了两项任务在行为数据中观察到的模式，为当前关于冲突任务中视觉和听觉信息处理的文献增添了生理证据。
