Hypnotically created pseudomemories: further investigation into the "memory distortion or response bias" question.

In order to study whether pseudomemories represent actual memory distortions or are a result of response bias, 60 highly hypnotizable subjects and subjects from the general population were divided into 4 experimental groups and were tested for pseudomemory manifestation after receiving a false suggestion. Of the 4 groups of subjects, 3 were offered a monetary reward as a motivation to distinguish false suggestion from actual occurrence. Pseudomemory manifestation was found to be significantly higher among subjects not offered a reward than among subjects who were offered such an reward. The implications of these findings are discussed.

Modifying hypnotic suggestibility with the Carleton Skills Training program.

The Carleton Skills Training (CST) program was used to investigate (a) whether increases in hypnotic responsiveness obtained at Carleton University could be replicated at a different laboratory, (b) the influence of demand characteristics on suggestibility gains, and (c) whether initial gains are maintained over time. After two screening sessions, a replication and experimental group received the CST program, while a control group was allowed to practice hypnotic responding. All groups were then tested twice. Whereas the replication group was told that training and testing were part of the same experiment, the experimental group was told that training and testing were unrelated. Trained subjects returned after 4 months for a final session. Results indicated that (a) the CST program does increase hypnotic responsiveness, (b) suggestibility gains found in this study were relatively modest, (c) demand characteristics may influence suggestibility gains, and (d) suggestibility gains were not maintained at follow-up.

Sexual stereotyping of black males in interracial sex.

Beliefs about black males' sexuality are pervasive in this society, but little studied. This investigation examined white subjects' perceptions of black and white characters in sexually explicit stories, some of which depicted interracial pairings. The perceptions were then examined in relationship to authoritarianism and sexual repression. Overall results suggest that black males are stereotyped as more potent than white males. The theoretical implications of this finding are discussed.

A social-learning approach to student marijuana use.

Three hundred seventy-two college students were administered a battery of questionnaires designed to assess the predictive power of four social variables (social support, perceived sanctions, availability, family models), and six psychological ones (locus of control, mortality-conscience guilt, personal meanings, functions for continuing use, belief in consequences, societal and non-societal means of valued goal attainment) with respect to marijuana use. Results support a social learning theory interpretation of marijuana use. Users have had pleasant experiences, believe that sanctions are minimal, and that marijuana is not harmful. Six predictor variables correlated +.76 with use.

A comparison of chronic versus casual marijuana users on personal values and behavioral orientations.

Fifty-one chronic (daily) long-term marijuana smokers and 32 casual (1 to 3 times per week) users were interviewed and given a Rokeach Value Survey, a Personal Orientation Inventory (POI), and a Zuckerman Multiple Affect Adjective Check List. Value survey results showed that the two groups had the same general value structure. The POI showed no differences between the groups, and the adjective self-ratings were similar. The groups were significantly different on a number of social variables; number of user friends, longest period without drugs, perceived risk, etc., which indicated "drug subculture involvement." Results are discussed from a sociological point of view.
