This study was designed to determine whether junior college freshmen demonstrate heterogeneity or homogeneity along certain personality dimensions. The subjects were 259 students enrolled in their first semester at California junior college. The two personality measures administered were the Adaptive-Flexibility Inventory, to measure the degree of ego strength of the respondent, and the Omnibus Personality Inventory, to assess certain characteristics of human behavior in areas of normal ego functioning and intellectual activity. Homogeneity was found on the measure of Adaptive-Flexibility--subjects scored more in the middle range on this measure than populations of normally functioning adults who had taken the test in earlier studies. On the Omnibus Personality Inventory, the patterns of response showed high impulse expression and low cognitive orientation. Standard deviations of mean scores on this instrument were lower than those of comparison groups. Generally, the kinds of data obtained from this investigation do not suggest the quality of heterogeneity usually ascribed to junior college students. Further research is suggested to determine the degree of heterogeneity or homogeneity, and on what variables. If the homogeneity found in this study is substantiated in future studies, it would show that junior colleges do not attract extremes, but rather a large number of students from a fairly homogeneous population.
