This study aimed to investigate whether dance education experiences have any impact on reaction times and physical synchrony when responding to auditory and visual stimuli. The main focus of this study was on the relationship between auditory and visual stimuli in generating synchronized body movements. The study included 11 healthy adults who were asked to perform knee extension and flexion movements in reaction to visual and auditory stimuli. The stimuli consisted of circles moving up and down at different frequencies, and participants were instructed to perform the movements in response to the stimulus for a period of 1 minute per trial. The presentation of the stimulus was random and occurred at six different speeds: 0.2, 0.4, 0.6, 0.8, and 1.0/1.2 Hz to prevent participants from acquiring a sense of rhythm. The collection of audio and visual stimuli, as well as the corresponding knee joint movements, were continuously documented. This study was demonstrated that reaction times were more rapid when behaviors were prompted by visual stimuli as opposed to a combination of visual and auditory stimuli. Additionally, the study found that reaction time was prolonged when the knee was in an upward position with the knee extended, and in a downward position with the knee bent. These findings were observed in Japan, where dance education has recently been implemented. This suggested that performing the down rhythm of lowering the hips with sound may be more challenging.
