Hearing a groove rhythm (GR), which creates the sensation of wanting to move to the music, can also create feelings of pleasure and arousal in people, and it may enhance cognitive performance, as does exercise, by stimulating the prefrontal cortex. Here, we examined the hypothesis that GR enhances executive function (EF) by acting on the left dorsolateral prefrontal cortex (l-DLPFC) while also considering individual differences in psychological responses. Fifty-one participants underwent two conditions: 3 min of listening to GR or a white-noise metronome. Before and after listening, participants performed the Stroop task and were monitored for l-DLPFC activity with functional near-infrared spectroscopy. Our results show that GR enhanced EF and l-DLPFC activity in participants who felt a greater groove sensation and a more feeling clear-headed after listening to GR. Further, these psychological responses predict the impact of GR on l-DLPFC activity and EF, suggesting that GR enhances EF via l-DLPFC activity when the psychological response to GR is enhanced.
听到凹槽节奏（GR），会让人产生想要随着音乐移动的感觉，也能让人感到愉悦和兴奋，它可能通过刺激前额叶皮层来提高认知表现，就像运动一样。在这里，我们假设 GR 通过作用于左背外侧前额叶皮层（l-DLPFC）来增强执行功能（EF），同时考虑到心理反应的个体差异。51 名参与者接受了两种条件：听 3 分钟的 GR 或白噪声节拍器。在听之前和之后，参与者执行 Stroop 任务，并通过功能近红外光谱监测 l-DLPFC 活动。我们的结果表明，GR 增强了 EF 和 l-DLPFC 活动，在那些感觉凹槽感更强、听 GR 后感觉更清醒的参与者中更为明显。此外，这些心理反应预测了 GR 对 l-DLPFC 活动和 EF 的影响，表明当对 GR 的心理反应增强时，GR 通过 l-DLPFC 活动增强 EF。
