This is a study of differential student recruitment and of changes in student characteristics at 3 highly selective, distinguished liberal arts colleges; 3 church-related colleges; and 2 large public institutions. The findings indicate how students changed from institution to institution in relation to their characteristics at entrance. These characteristics included educational and vocational values; religious, political, and civic attitudes; personality characteristics; and intellectual disposition. Intellectual disposition was a construct and continuum in which one extreme represented broad intellectual and esthetic interests, theoretical orientation, and intellectual independence, and the other extreme represented a practical orientation, conventional and less flexible forms of thought, and lack of esthetic interests. The only statistically significant evidence of differential change in intellectual disposition was the percentage of students in one of the elite colleges who changed from a pronounced pragmatic to a pronounced theoretical orientation over the 4 years. The report of the study summarizes changes on the several scales of the Omnibus Personality Inventory and changes in attitudes and values. (Author/HS)
