Abstract: The problem investigated in this study was the relationship between the frequencies and durations of selected behavioral categories in a group of two-year-old children and time of day. Specifically, the question asked was, do two-year-olds' behaviors change in a free play setting in a nursery school as a function of time of day? It was hypothesized that there would be no group differences in either frequency or duration of behavior at different times of the day in similar preschool settings. The question was investigated by means of ethological, observational techniques, utilizing videotape technology in the data collection process. The subjects observed were eight two-year-old children concurrently enrolled in a morning nursery school program at Centenary United Methodist Church and an afternoon nursery school program in the Department of Child Development and Family Relations at the University of North Carolina at Greensboro. There were two major time groups, morning and afternoon, and two afternoon time sub-groups, early afternoon (1-2 p. m.) and late afternoon (3-4 p.m.). The subjects were all of the middle socio-economic structure.
