Using Tiffany's (1990) cognitive model of drug use and craving as a theoretical basis, the present experiments investigated whether cravings for food expend limited cognitive resources. Cognitive performance was assessed by simple reaction time (Experiment 1) and an established measure of working memory capacity, the operation span task (Experiment 2). In each experiment, female undergraduate students were randomly assigned to a craving or control condition. Participants in the craving condition abstained from eating chocolate for 24 hours prior to testing and performed the cognitive task in the presence of chocolate, a manipulation that successfully elicited chocolate cravings. In both experiments, there was no main effect of craving condition on cognition, but there was a significant interaction between condition and trait chocolate craving. In support of Tiffany's model, our results show that habitual food cravers direct limited cognitive resources to craving-related cues, at the cost of competing cognitive demands.

This study examined the psychometric properties of the Revised Illness Perception Questionnaire adapted for a clinical sample of low-income Latinos suffering from depression. Participants (N = 339) were recruited from public primary care centers. Their average age was 49.73 years and the majority was foreign born females of either Mexican or Central American descent. Confirmatory factor analysis was used to test the factor structure of this measure. Construct and discriminant validity and internal consistency were evaluated. After the elimination of three items because of low factor loadings (< .40) and the specification of seven error covariances, a revised model composed of 24 items had adequate goodness-of-fit indices and factor loadings, supporting construct validity. Each of the subscales reported satisfactory internal consistency. Intercorrelations between the 5 illness perception factors provided initial support for the discriminant validity of these factors in the context of depression. The establishment of the psychometric properties of this adapted measure will pave the way for future studies examining the role illness perceptions play in the help seeking and management of depression among Latinos. 相似文献

The present study examined prevalence of lack of a close confidant in a medically underserved primary care sample, and evaluated demographic, medical, and psychological correlates of patients' deficits in close, personal contact. Adult patients (n = 413) reported on confidant status and symptoms of depression and anxiety. Sociodemographic and medical information were obtained through chart review. One-quarter of patients endorsed lack of a close confidant. Past month anxiety and depression symptoms, but not medical status, were associated with unmet socioemotional needs. Implications for primary healthcare interventions are discussed. 相似文献

The contribution of past experiences to concurrent resurgence was investigated in three experiments. In Experiment 1, resurgence was related to the length of reinforcement history as well as the reinforcement schedule that previously maintained responding. Specifically, more resurgence occurred when key pecks had been reinforced on a variable-interval 1-min schedule than a variable-interval 6-min schedule, but this effect may have been due either to the differential reinforcement rates or differential response rates under the two schedules. When reinforcement rates were similar (Experiment 2), there was more resurgence of high-rate than low-rate responding. When response rates were similar (Experiment 3), resurgence was not related systematically to prior reinforcement rates. Taken together, these three experimental tests of concurrent resurgence illustrate that prior response rates are better predictors of resurgence than are prior reinforcement rates. 相似文献

Color can strongly affect participants' self-report of an odor's qualities. In Experiment 1, we examined whether color influences a more objective measure of odor quality, discrimination. Odor pairs, presented in their appropriate color (e.g., strawberry and cherry in red water), an inappropriate color (e.g., strawberry and cherry in green water), or uncolored water were presented for discrimination. Participants made significantly more errors when odors were discriminated in an inappropriate color. In Experiment 2, the same design was utilized, but with an articulatory suppression task (AST), to examine whether the effect of color was mediated by identification or by a more direct effect on the percept. Here, the AST significantly improved discrimination for the inappropriate color condition, relative to Experiment 1. Although color does affect a more objective measure of odor quality, this is mediated by conceptual, rather than perceptual, means. 相似文献

Various theoretical approaches to therapy place different emphases on the use of power in therapy. In this study, we explore six master therapists’ use of power via communicational control for theoretical consistency. Results indicate that all therapists, regardless of their stance on power, use the role of therapist to exert power in an initial therapy session. Master therapists, in general, did appear to be theoretically consistent with their stated philosophies of therapy. Suggestions for future studies exploring power therapists have are included. 相似文献

The present study empirically investigated the role of adaptive and maladaptive components of humour in the relation between attributional style and dysphoria. Four hundred eighteen students (134 male, 282 female; 2 respondents did not indicate gender) completed questionnaires measuring attributional style, humour styles and depressive symptoms. Among men and women, higher levels of affiliative and self‐enhancing humour, and lower levels of self‐defeating humour, were each associated with fewer depressive symptoms. Additionally, higher levels of affiliative humour provided a buffer against the deleterious effects of a negative attributional style in men, but not women.

Previous research has shown that most women in the United States support feminist goals but do not label themselves as feminists. Concern over other people’s opinions of feminists may predict rejection of the feminist label. In the present study we predicted that feminists would be more likely than non-feminists to believe that other people view feminists favorably. One hundred seventy-one female participants completed the Berryman-Fink Semantic Differential Scale twice, once to indicate how they view feminists and again to indicate how they believe others view feminists. Contrary to our hypothesis, all women, regardless of feminist identification, believed that others view feminists negatively and as more likely to be homosexual than heterosexual. Relationships between participants’ own views of feminists and their perceptions of others’ views of feminists were explored. Transformative experiences that may lead a feminist to ignore their perception of society’s views are discussed. 相似文献
