Skin conductance responses to real and imagined snakes among avoidant and non-avoidant college students

Experiment I compared the extent to which, at the physiological level, behaviorally avoidant and non-avoidant Ss respond differently to in vivo exposure to a snake. Experiment II tested an hypothesis about possible confounding in the procedures of Experiment I. Experiment III was a replication of Experiment II except that an imagined snake was substituted for the real snake. The three experiments were designed to permit simultaneous comparisons involving the skin conductance reactions of avoidant and non-avoidant volunteer Ss to a snake and to a neutral stimulus. In Experiments II and III differential responsivity in the expected direction was found. These differences were discussed in connection with the methodology of snake-avoidance therapy analogues.     

Subjective ratings of credibility following brief exposure to desensitization and pseudotherapy

Forty-two Ss were selected as if they were to participate in an analogue desensitization experiment. They then listened to taped excerpts of desensitization and pseudotherapy and responded to a questionnaire assessing the relative credibility of the two treatments. Desensitization was found to be more credible than pseudotherapy. The implications of this finding for previous and future research are discussed.     

Reduced information feedback on a selection concept learning task

A procedure to reduce information feedback on selection concept learning problems with nonfixed solutions is described. It has an advantage over similar procedures since it requires no electronic equipment. Female college students solved four concept problems under reduced or standard feedback conditions. The results showed more card choices to solution with reduced feedback and no differences on the other measures. Questionnaire data revealed no significant differences between feedback conditions in perceptions of the task.     

Heterosexual anxiety: Stable multichannel assessment for therapy outcome research

Thirty-six shy males participated in two interpersonal performance tests with attractive female confederates. Between the two interpersonal performances, each was exposed either to one of three elaborate placebo treatments or to no treatment. During and after each performance, heterosexual anxiety was measured with instruments recommended for research purposes by Borkovec et al. (1974). Results showed that the recommended shyness measures were immune to unwanted changes either from repeated assessments or from any of the three multisession placebo procedures. Hence the experiment partially replicated and substantially extended previous research, suggesting the feasibility of using the Borkovec et al. shyness-assessment package in behavioral fear-therapy research.     

Fear or Moral Indignation? Predicting Attitudes Toward Parolees1

Instrumental beliefs, value-expressive beliefs, and attitudes related to parolees were investigated in 2 contexts. In Study I, students (N= 180) responded to value-expressive measures in a mass survey and then, a month later, read 2 scenarios and completed measures of instrumental beliefs, attitudes, and intentions. Instrumental beliefs were better predictors of behavioral attitudes than were value-expressive beliefs. In Study 2, the format of the measures was altered and all measures were administered concurrently. As in Study I, results showed that instrumental beliefs were consistent and strong predictors of attitudes toward parolees. Attitudes related to parolees appear to be based more on practical concerns (instrumental beliefs) than on moral or symbolic issues (value-expressive beliefs).
