Several theories of decision making are based, in part, upon the principles of psychophysics (Kahneman and Tversky, 1979; Thaler, 1985). For example, due to the psychophysics of quantity, the difference between $10 and $20 seems greater than the difference between $110 and $120. To determine whether psychophysics influences consumers' decisions, subjects in four studies made real or hypothetical purchases. It was predicted that as the size of the purchase increased, subjects would be more willing to buy additional smaller items. Small extra purchases should seem like minor expenditures when they follow larger purchases. Results of the four studies supported our hypothesis. In addition, it was found that subjects responded not only to actual changes in purchase size but also to changes in the presentation or framing of a purchase. 相似文献

This article presents ideas and reflections emerging during a project on family therapy with drug abusers. Initially inspired by the writings of Stanton and Todd on the subject, the project developed into a recursive and self-reflective process, characterized by increasing doubts about the usefulness of categorization of families, of pre-planning therapy, and of the therapist as an "expert." The limitations of approaches that emphasize the importance of understanding the family structure as the basis for changing it are discussed, particularly with respect to how they decrease therapist flexibility and may block the family's finding their own solution. Alternative approaches to practice and research are also discussed, bearing on ideas particularly formulated by theoreticians and practitioners inspired by second-order cybernetics. 相似文献

Outcome research has shown that partner-spouse support can enhance the therapeutic outcome in a number of clinical problems. In the area of premenstrual tension, studies of treatment have apparently overlooked this issue of partners' support. This study was designed to address how men perceive premenstrual changes. 99 undergraduate men were asked whether they believed that women had premenstrual changes reflected on the 18 unipolar scales of the Premenstrual Assessment Form. Responses suggest that young men acknowledge that some women experience dysphoric features like hostility, mood swings, and low self-esteem as well as physical discomfort and behavioural changes. Clinical implications are outlined. 相似文献

Investigated the validity of the hypothesis that subjects would experience arousal if they received information suggesting that they were presenting themselves to others in a negative manner. Twenty-seven subjects were randomly assigned to a control, evaluation apprehension, or negative feedback group. Subjects' heart-rate was continuously monitored as subjects' rated a series of photographs. Subjects in the evaluation apprehension group were given a cue as to how to present themselves positively whereas subjects in the negative feedback group were told, following their response to the 15th photograph, that their responses suggested maladjustment. Heart-rate change above a baseline measure revealed that an increase in heart-rate occurred only when subjects were informed that they were transmitting negative information. Such a finding supports a positive self-presentation explanation of subject motives in the psychological experiment. 相似文献
