The effect that four years of college has on student personality test scores was examined at Shippensburg State College. The personality measure administered in all three Centennial Class testings was the "Runner Studies of Attitude Patterns". The 14 Runner variables are categorized as control-oriented, freedom-oriented, affiliation-oriented, and recognition-oriented. Tentative findings of the study included the following: (1) The impact of college experiences on student personality scores was clearly evident. (2) Different sets of variables seem to have had early or late impact changes. Variables changing within the first two years of college taken together suggest a receptiveness to new experience; the last two years seemed to display a sobering period. (3) Males and females experienced largely similar personality adjustments, though there were differences in intensity and significance of some variables. (4) An analysis by self-labelled political philosophy showed liberal and middle-of-the-road students followed a four-year pattern of continuous change in scores. (5) Students grouped by college curriculum also showed varying patterns of change of personality scores through college. (Author/LBH)
