Objective: The main purpose of this study was to investigate the relationship between circadian typology and reaction time in the morning and evening. The other aim of this I research was to study the differences of reaction times in the morning and the evening I among students.
Method: In a cross-sectional study 65 students of Isfahan University (36 females, 29 males) were randomly selected. Data were collected using Morningness- Eveningness Questionnaire and Visual Reaction Time Task. For evaluating the day time effect on subject performance, reaction time was tested twice (9 A.M. and 3 P.M.).
Results: There was no relation between Morningness-Eveningness scores and reaction time. Also, there was no difference between reaction time scores at two performances (morning and evening). Multivariate analysis showed a significant difference between males and females in Morningness-Eveningness scores (p<0.006). However, there was no significant difference between the two sexes in reaction time.
Conclusion: There is no significant difference between reaction time and circadian typology. Since the Morningness-Eveningness scores of subjects in this study belonged to neither type in circadian typology, there is a possibility I that this has affected the reaction time test results. Different results might be obtained if the. Subjects are selected from two ends of the continuum (morningness and eveningness).
