Sensorimotor synchronization (SMS) refers to the temporal coordination of an external stimulus with movement. Our previous work revealed that while SMS with visual flashing patterns was less consistent than with auditory or tactile patterns, it was still evident in a sample of nonmusicians. Although previous studies have speculated the potential role of auditory imagery, its contribution to visual SMS performance is not well quantified. Utilizing a synchronization-continuation finger-tapping task with a visual stimulus that included implied motion, we aimed to examine how participants' imagery ability, musicality, and rhythm perception affected SMS performance. We quantified participants' SMS consistency in synchronization (with visual cues) and continuation (without visual cues) phases. Participants also performed a perception task assessing their ability to detect temporal perturbations in the visual rhythm and completed musical ability and imagery questionnaires. Our linear regression model for SMS consistency included the trial phase, self-reported auditory imagery control and musicality, and visual rhythm perception as predictors. Significant effects of trial phase and auditory imagery scores on SMS consistency suggested that participants performed SMS more consistently while the guiding visual stimulus was present and that the higher one's self-reported auditory imagery ability, the better their SMS when continuing with unguided rhythm. One's visual rhythm perception accuracy significantly correlated with SMS consistency during the synchronization phase, and there was no correlation between rhythm perception and auditory imagery control. Overall, our results suggested relatively independent contributions of auditory imagery and visual rhythm perception to SMS with visual rhythm.

听觉意象和视觉节律感知对感觉运动与外部和想象节律的同步的贡献。


感觉运动同步（SMS）是指外部刺激与运动的时间协调。我们之前的研究表明，虽然具有视觉闪烁模式的短信不如听觉或触觉模式的一致，但在非音乐家样本中仍然很明显。尽管之前的研究推测了听觉意象的潜在作用，但它对视觉短信性能的贡献尚未得到很好的量化。利用同步连续手指敲击任务和包含暗示运动的视觉刺激，我们旨在研究参与者的想象能力、音乐性和节奏感知如何影响短信表现。我们量化了参与者在同步（有视觉提示）和延续（无视觉提示）阶段的短信一致性。参与者还执行了一项感知任务，评估他们检测视觉节奏中的时间扰动的能力，并完成了音乐能力和意象调查问卷。我们的 SMS 一致性线性回归模型包括试验阶段、自我报告的听觉意象控制和音乐性以及作为预测因素的视觉节奏感知。试验阶段和听觉想象分数对短信一致性的显着影响表明，当存在引导性视觉刺激时，参与者执行短信的一致性更高，并且自我报告的听觉想象能力越高，在继续不受引导的节奏时，他们的短信就越好。一个人的视觉节律感知准确性与同步阶段短信的一致性显着相关，而节律感知与听觉意象控制之间不存在相关性。 总的来说，我们的结果表明听觉意象和视觉节奏感知对带有视觉节奏的短信的贡献相对独立。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
