Inexperienced beer-drinkers who could not pass a beer-flavor discrimination test were divided into a taste group, which received additional perceptual experience with beer flavors; a verbal group, which received instruction in beer flavor terminology; a taste/verbal group, which received both additional experience and instruction; and a control group. Before and after training, all subjects participated in a similarity rating task involving beer flavors and flavor-related adjectives. Additional taste experience--but not increased experience with beer-flavor terminology--improved novices' ability to detect identical beer flavors. Results are discussed in terms of the trainability of flavor discrimination and the role of cognitive factors (both flavor-related and flavor-independent) in marketing beverages. 相似文献

The effect of mood and pleasant versus unpleasant information feedback on performing a motor skill 总被引:1,自引:0,他引:1

The effect of negative, positive, or neutral feedback on a rotary pursuit task as a function of the subject's depressed or elated mood was ascertained. Specifically, the self-schema hypothesis was examined. Ninety female volunteers, ranging in age from 18 to 25 years, participated. They were randomly assigned to one of eight conditions based on depressed or elated mood states, elicited by Velten's (1968) mood induction procedure, and feedback. A control group received no feedback and was not subjected to a mood inducing treatment. Baseline measures and changes in mood were determined by the Multiple Adjective Affective Checklist (MAACL). Bogus feedback was offered after all but one of the trials. The subjects' mood changed significantly during the mood-inducing treatment. For motor performance, partial support was lent to self-schema. Elated and depressed subjects performed best under positive and negative feedback, respectively. The effects, however, were temporary. 相似文献

In this study the authors compared women's and men's reactions to various professional travel situations. A multivariate analysis of covariance was used to determine the effects of sex, professional role, and years traveling on the perceptions of these travel situations. 相似文献

The present study demonstrates the safety and effectiveness of an outpatient program designed to respond to adolescent-precipitated crises by mobilizing and restructuring the family's kinship system. Families of 75 adolescents at risk for hospitalization were followed up to 24 months after treatment with Systemic Crisis Intervention. Measures of offspring and family functioning, suicidal behavior, institutional use, and treatment costs are presented. Results clearly demonstrate the safety, effectiveness, and economic viability of Systemic Crisis Intervention. 相似文献

The Family System Functioning (FSF) scale is a new instrument for measuring dimensions of the intrafamilial environment thought to be important in recovery from major psychiatric illness. Modest statistical correlations were obtained when FSF ratings of laboratory-based family interactions were compared with researcher-guided therapist ratings of FSF based upon the family's behavior in family therapy sessions during the subsequent month. The data from these two settings provide support for the validity of some of the scales. Because of the modest size of the correlations, however, behavior in the laboratory setting may not always be an accurate indicator of how the family will behave in the early weeks of family therapy. 相似文献
