In this study of time perception of Chinese university students, a questionnaire was used to determine (a) the frequency of their being late in social engagements; (b) their feelings of being late; (c) their perceptions of earliness and lateness; (d) the attributions they would make in case of being late; and (e) their evaluation of the personality of people who were punctual, occasionally late, or chronically late. When the results were compared with those of American and Brazilian college students reported by Levine, et al. (1981), Chinese subjects seemed to have a more strict sense of punctuality. While they set a greater allowance for early corners in social gatherings, they showed less tolerance than the Westerners did for late corners; and they themselves would always try to be present ahead of the scheduled time. The accuracy of public clocks and personal watches was also checked in this study at fifteen localities in Taiwan area. No systematic difference was found between the accuracy of those time pieces in big cities and that of those in small towns.
