This study investigated the effect of television food commercials on children's self-control within a resistance to temptation paradigm. Commercial type, food stimulus type, and the child's sex provided the three independent variables in a 4 × 4 × 2 factorial design. Behavioral and self-report indices of temptation and control were measured. Children were significantly more tempted to transgress for the low-nutrition food, regardless of the commercial shown. Sex differences in reported degree of temptation were found. However, the television commercials did not affect the children's latency to transgress.  相似文献

The knew-it-all-along effect is investigated by comparing pre- and post-election predictions of subjects concerning three electoral races in the November 1984 elections. The results revealed that when the outcomes of the predictions are known, subjects recall having assigned higher probabilities and percentages to the actual winners of each election, remember having more confidence in the accuracy of these percentages, and claim to have had more knowledge of the candidates than they had before the election. The results were consistent across all three elections and in both repeated-measures and between-pups designs, suggesting that the knew-it-all-along effect is a very robust one. Two underlying processes are hypothesized to account for these results: the availability heuristic and an increase in confidence explanation.  相似文献

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

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
