Some implications for psychological research of early versus late term participation by college subjects

Several surveys of recent psychological literature have indicated that a large percentage of human subjects are introductory psychology students who are given the option of selecting when to participate in research which is either implicitly or explicitly required of them. The present study was conducted to investigate the possibility that those subjects who choose to participate early in the term differ in personality and in attitudes toward research from later term participants. Results indicated that early term males and females, as expected, were more academically oriented and more internally controlled than late term subjects; and early term males were more achievement oriented than their late term counterparts. Additionally, females were found to feel more positive toward research participation than males; while a large percentage of all subjects reported both suspiciousness of experimenter intent and a general and unexpected willingness to voluntarily participate as subjects. Possible effects of these findings on research results and conclusions were discussed, and suggestions for improvements aimed at reducing self-selection bias in college subject pools were made.     

The Anatomy of Revolutionists

A questionnaire containing 62 items relating to the New Left and 28 items measuring anomia, authoritarianism, and Machiavellianism was given to 153 entering freshmen at Columbia in the fall of 1968. The five factors emerging from a factor analysis of responses to the items were labeled: New Left Philosophy, Revolutionary Tactics, Machiavellian Tactics, Machiavellian Cynicism, and Traditional Moralism. Students who had been politically active prior to coming to college scored higher than the rest of the group on New Left Philosophy, Revolutionary Tactics, and Machiavellian Cynicism, but scored lower on Machiavellian'Tactics and Traditional Moralism. In the spring of 1969, a revised set of items was given to students in introductory psychology classes at Columbia University and New York University. While the findings from these subjects replicated those found with the Columbia freshmen, they showed subtle differences which led to speculations about the radicalization process. Also discussed are the relationships between the nature of political participation and all of the factors, with special emphasis on the discrepancy between Machiavellian Tactics and Cynicism.     

A developmental study of school theft

Two hundred students in grades 4-8 and 10 participated in a study of school theft. Students responded to a four-part questionnaire designed to measure perceptions of theft incidence and seriousness, personal responsibility for correcting theft, causal attributions of theft, and perceived consequences of thievery. A main grade effect was observed for personal responsibility and consequences, but represented counter directions. Eighth graders reported the highest incidence of theft, and females prescribed harsher penalties for theft. Results only weakly support a developmental interpretation of school theft patterns. Overall, students uniformly report that theft is a major problem in their schools.
