Many philosophers and masters have instructed learners to pay attention to their word usage because words can sometimes facilitate the development of physical skills but at other times it can be an obstacle or a hindrance. Then, the purpose of this study was set to examine the effects of word usage on responses of physical skills. As a method, 17 subjects were instructed to take a perceptual response test in which red and blue were randomly displayed. Specifically, the control task (CT) was defined as a subject’s saying "yes (hai)" regardless of whether a red or blue circle was displayed, whereas the target task (TT) was defined as a subject’ saying "red (aka)" when a red circle was displayed and "blue (ao)" when a blue circle was displayed. The results showed that 14 subjects had slower response times for TT than CT in terms of the mean response time. Welch's t-test was conducted on the response time data of CT and TT for all subjects, finding significant differences (p<.05). The t-test which was also performed on the response times in both tasks for each subject recognized a significant difference (p<.05) for 5 subjects, and the calculation of Hedges' g, the effect size, found that 6 subjects had a value of 0.5 or more. The discussion suggested that response times for TT took longer due to the cognitive resource load of TT compared to CT, revealing that word usage may influence the response of physical skills.
