反应抑制在预防我们日常生活中预期和不可预测的事件方面起着至关重要的作用。它分为前摄抑制和反应性抑制，前摄抑制是受试者推迟对即将到来的信号的反应，反应性抑制是受试者根据信号的呈现停止即将到来的运动。不同类型的感觉输入都参与了这两种抑制，然而，在前摄和反应性抑制与感觉方式的差异仍不清楚。该研究使用选择反应任务（CRT）和停止信号任务（SST）比较了视觉、听觉和体感信号引起的主动和反应性抑制。实验结果表明，前摄抑制在听觉和躯体感觉模态中显著高于视觉模态，而反应性抑制则不然。检查前摄抑制相关的神经处理，听觉和体感方式显示，在P3振幅在去信号锁定事件相关电位（ERP）在SST相对于CRT的显着下降，这可能反映了减少注意力资源在SST中的响应执行在这两种方式。相反，我们没有发现反应性抑制相关的ERP的显着差异。这些结果表明，前摄抑制不同的感觉方式，而反应性抑制没有。
Response inhibition plays an essential role in preventing anticipated and unpredictable events in our daily lives. It is divided into proactive inhibition, where subjects postpone responses to an upcoming signal, and reactive inhibition, where subjects stop an impending movement based on the presentation of a signal. Different types of sensory input are involved in both inhibitions; however, differences in proactive and reactive inhibition with differences in sensory modalities remain unclear. This study compared proactive and reactive inhibitions induced by visual, auditory, and somatosensory signals using the choice reaction task (CRT) and stop-signal task (SST). The experiments showed that proactive inhibitions were significantly higher in the auditory and somatosensory modalities than in the visual modality, whereas reactive inhibitions were not. Examining the proactive inhibition-associated neural processing, the auditory and somatosensory modalities showed significant decreases in P3 amplitudes in Go signal-locked event-related potentials (ERPs) in SST relative to those in CRT; this might reflect a decreasing attentional resource on response execution in SST in both modalities. In contrast, we did not find significant differences in the reactive inhibition-associated ERPs. These results suggest that proactive inhibition varies with different sensory modalities, whereas reactive inhibition does not.
