Inhibitory control, as an essential cognitive ability, affects the development of higher cognitive functions. Rhythmic perceptual stimulation has been used to improve cognitive abilities. It is unclear, however, whether it can be used to improve inhibitory control. This study used the Go/NoGo task and the Stroop task to assess various levels of inhibitory control using rhythmic audio-visual stimuli as the stimulus mode. Sixty subjects were randomly divided into three groups to receive 6 Hz, 10 Hz, and white noise stimulation for 30 min. Two tasks were completed by each subject both before and after the stimulus. Before and after the task, closed-eye resting EEG data were collected. The results showed no differences in behavioral and EEG measures of the Go/NoGo task among the three groups. While both 6 Hz and 10 Hz audio-visual stimulation reduced the conflict effect in the Stroop task, only 6 Hz audio-visual stimulation improved the amplitude of the N2 component and decreased the conflict score. Although rhythmic audio-visual stimulation did not enhance response inhibition, it improved conflict inhibition.
抑制控制作为一种重要的认知能力，会影响高级认知功能的发展。节律性感知刺激已被用于提高认知能力。然而，尚不清楚它是否可用于改善抑制控制。本研究使用Go/NoGo任务和Stroop任务，以节律性视听刺激作为刺激模式来评估不同水平的抑制控制。60名受试者被随机分为三组，分别接受6Hz、10Hz和白噪声刺激30分钟。每个受试者在刺激前后都完成两项任务。在任务前后，收集闭眼静息脑电图数据。结果显示，三组在Go/NoGo任务的行为和脑电图测量上没有差异。虽然6Hz和10Hz的视听刺激都降低了Stroop任务中的冲突效应，但只有6Hz的视听刺激提高了N2成分的波幅并降低了冲突分数。虽然节律性视听刺激没有增强反应抑制，但它改善了冲突抑制。
