The present study investigated the effects of subjects' outcome expectancy on self-monitoring of a clinically relevant behavior, overeating. In conjunction with self-monitoring of eating habits, subjects received either a positive expectancy of behavior change or no expectancy regarding change. While both self-monitoring groups achieved significantly greater weight loss than controls, subjects in the expectancy group demonstrated significantly greater weight loss than no-expectancy subjects. Possible factors accounting for the disparity in findings between this and previous self-monitoring investigations are discussed. 相似文献

In order to investigate the impact of high ambient temperature on the motivation of angered persons, 48 men were either insulted or not insulted under normal or excessively hot conditions. The men received ratings from a partner that conveyed a negative or neutral personality evaluation, ostensibly as part of an impression-formation task. During this time, the participants were exposed to normal or excessively hot temperatures in an experimental room while their partners were in a normal temperature room. The subjects were subsequently given the opportunity to choose between two tasks for the next part of the study. One task, described as tedious, permitted their leaving the situation earlier than did the other task, described as involving administration of white noise to their partner. The results revealed that the insulted relative to noninsulted men more often chose to participate in a potentially aggressive interaction in the normal conditions whereas insulted relative to noninsulted men chose more often to participate in a nonaggressive task in the hot conditions. The design of the study precluded a shared stress interpretation of the data. Supplementary data were interpreted as supporting a negative affect rather than an attributional interpretation of the results. 相似文献

Occupational Achievement Motivation as a Function of Biological Sex, Sex-Linked Personality, and Occupation Stereotype 总被引:1,自引:0,他引:1
Predicted sex differences in occupational achievement motivation based on the work of Horner (1968) and Stein, Pohly and Mueller (1971) were examined by administering questionnaires to 87 female and 91 male undergraduate psychology students. Subjects made six achievement related responses to twelve occupations which had been stereotyped by a separate group of subjects as being either high prestige masculine, middle prestige masculine, middle prestige feminine or middle prestige androgynous (appropriate for both sexes). Analyses of variance were performed on all achievement responses with subjects'sex, sex-linked personality (Spence, Helmreich & Stapp, 1974), and occupational stereotype as independent variables. Significant sex by occupation stereotype interactions were found on all six dependent measures supporting the Stein et al. prediction of highest achievement motivation toward sex appropriate occupations. The fact that females did not show significantly lower motivation than males toward high prestige masculine occupations is inconsistent with earlier findings. Sex-linked personality was related to some of the achievement measures but did not interact with either occupation stereotype or biological sex. 相似文献

Seventy-four obese TOPS (Take Off Pounds Sensibly) members were assigned to one of five conditions: delayed treatment control, insight psychotherapy, self-management training plus external reinforcement, self-management training only, or external reinforcement only. The latter four groups met once per week for ten weeks and were seen at three and six months and followup. It was hypothesized that self-management plus external reinforcement would be superior to other conditions at both post-treatment and followup, and that this condition alone would produce continuing weight losses. Analysis of covariance on body weight, with pretreatment weight as covariate, indicated that self-management plus external reinforcement, self-management only, and external reinforcement only, did not differ in mean body weight at post-treatment. These three groups differed significantly from control and psychotherapy conditions, which did not differ from one another. Self-management plus external reinforcement produced better performance of techniques. At three and six month followup, differences between the four treatment conditions were no longer significant. Results are discussed in terms of evaluation of psychotherapy and behavior modification and durability of results. 相似文献

NEWBORNS FORM "PROTOTYPES" IN LESS THAN 1 MINUTE 总被引:1,自引:0,他引:1
Abstract— Past research demonstrated that newborns looked longer at live faces and two-dimensional still images of the mother than at the faces and images of strangers (Bushnell, Sai, & Mullin, 1989; Field, Cohen, Garcia, & Greenberg, 1985; Walton, Bower, & Bower, 1992). This study examined schema (prototype) theory as a basis for newborn's preference for the mother's face by creating composite (prototype) faces with a pixel averaging technique. Results obtained with a preferential operant-sucking procedure indicated that formation of a representation of faces was rapid. Newborns preferred to look at a composite of presented faces rather than a composite of unseen faces on the first-look presentation of each. The effect faded over the duration of the experiment. 相似文献

This paper examines two dimensions of concurrent verbal protocol validity. First, whether verbalization affects process and outcome (reactivity) was examined by comparing concurrent verbal protocol traces with those from a computer search process tracing method, the latter being a complete trace of information acquisition from experimental materials. Earlier findings that verbalization affects time were confirmed. However, verbalization did not affect amount and pattern of acquisition or accuracy of judgments. Second, whether concurrent verbal protocols are complete was examined by comparing concurrent verbal protocol and computer traces that were simultaneously obtained in a treatment in which subjects verbalized as they acquired information from the computer. The verbal traces less completely captured information acquisition behavior than computer search. This suggests that, although concurrent verbal protocols provide greater insight into decision behavior than computer search, the latter is a more reliable information-acquisition trace. Thus, if information acquisition is of primary interest and if computer search activities can be naturally integrated into performing the primary task, computer search is preferred to concurrent verbal protocols. However, if information use or retrieval from long-term memory is of primary interest, concurrent verbal protocols are preferred to computer search. Finally, this paper examined whether the simultaneous use of concurrent verbal protocols and computer search provides traces of information acquisition and use that are as complete as when each method is independently applied. Although computer search tended to limit subjects verbalizations of evaluative operators, this effect may be eliminated by practice on the computer prior to collecting data. 相似文献

This paper argues for a multidimensional approach to the study of the social support networks of mothers and fathers of young children. Network structure (e. g. size, density, member characteristics), support content (e. g. emotional, informational, economic and child care) and support quality (e. g. helpfulness, satisfaction with support, conflict associated with support and willingness to access support in future need) are distinguished. The goals of the study were: (1) to empirically test the multidimensionality of parental support networks; (2) to assess the relations among these three dimensions for mothers and for fathers; and (3) to examine how couples' support networks are interrelated. Individual at-home interviews were conducted with 100 parents to derive measures of parental support structure, content and quality. Fathers (N = 31) were compared to their spouses (N = 31) and to a comparison group of demographically similar married mothers (N = 38). For all three groups, the same three predicted dimensions emerged in the factor structure of their networks; in general, few gender differences were found. However, relations among structure, content and quality differed by gender, with network structure predicting support content and quality only for mothers. The network structure of couples was positively correlated, and overlap in network members was related to own and spouse's network helpfulness, satisfaction and child care support. 相似文献

Although case studies can provide insight into children's eyewitness memory, the typical lack of objective record limits evaluation of accuracy. In contrast, in this ‘scientific case study’, a detailed record of child sexual assault, documented by a ‘sex ring’ leader and confiscated by police, was available. In police interviews and courtroom hearings, four girls (8 to 15 years old at time of report) testified about sexual exploitation that involved eight adult men. The girls' allegations were compared with evidence contained in photographic and audiotaped records of the abuse. Overall, there was supportive evidence for about 80% of the allegations (85.6% of the alleged sexual acts; 42.9% of the alleged coercive acts; and 82.5% of the alleged preparatory acts). Levels of support for sexual act allegations were similar for all four girls, regardless of age, but the younger child made more unsupported allegations of coercive behaviour. Additionally, there were high levels of omission errors. Findings are discussed in the context of research on eyewitness testimony and child sexual abuse. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献
