Abstract

The purpose of this study was to compare the motor memory function and the motivation of progress in male and female students with different daily rhythm. The statistical sample included 50 morning active participants (25 females and 25 males) and 40 evening active participants (17 females and 23 males). Research tools included Horn Stenberg's Morning-Evening Questionnaire, Hermann's Progress Motivation Questionnaire, and Chain Color Matching Software. Findings showed that the progression for the variable of motor memory function of the interactive effect of gender on the daily rhythm was not significant. Comparison of means showed that evening active males had the highest mean of motor memory, while morning active females had the weakest level of motor memory function. For the progress motivation variables, results showed that the interactive effect of gender and daily rhythm was not significant, but the main effect of the daily rhythm was significant. The results of Tukey post hoc test showed that there was a significant difference between the progress motivation in males with evening rhythm and progress motivation of females with morning rhythm. Male students with an evening rhythm had the lowest score of progress motivation, and female students with the morning rhythm had the highest score of progress motivation.
