The effects of receiving negative verbal weight-related feedback on the mood, self-esteem, and body image of restrained and unrestrained eaters were investigated. Female undergraduate students either reported their current weight (no feedback) or had their weight guessed as 15 lb higher than their actual weight (negative feedback) by an experimenter who presented herself as either an undergraduate (peer) or graduate student (non-peer). Participants overall had higher anxiety and felt “fatter” in the negative feedback condition. When this feedback came from a peer they felt fatter, more dissatisfied with their bodies, and, for restrained eaters, more depressed, as compared to when it came from a non-peer. These results provide empirical evidence that negative weight-related feedback produces adverse psychological consequences for young women, especially restrained eaters, and suggest the importance of peers’ perceptions of weight. 相似文献

运用词汇判断任务,考察了汉语双字词识别中的多义性效应。实验一运用2个真字任意组合构成的假词(如:镜社)作填充材料,发现多义词识别的优势效应仅仅存在于错误率中。实验二运用与源真词(如:冲锋)同音形似的假词(如:冲烽)作填充材料,促使被试更多地在语义水平上做出判断,结果发现很强的多义词识别的优势效应,这种效应主要表现在低频词上。两个实验结果表明,在词汇判断中用不同的假词作填充词会影响被试的词汇判断策略,从而在不同水平上通达词义。最后,用反馈模型对实验结果进行了解释。 相似文献

绩效反馈研究的回顾与展望 总被引:1,自引:0,他引:1
绩效反馈是组织中鼓励先进、鞭策落后、激发员工潜能的很重要的管理手段。该概要回顾了有关反馈的研究,分析了反馈研究的发展趋势,认为不同反馈来源中上级反馈的影响越来越重要;表扬还是批评的信息对员工的影响值得进一步探讨;反馈接受者本人的特点对反馈效果的影响研究应更加深入。 相似文献

Stimuli inevitably generated by behavior that avoids electric shock are inherently reinforcing. 下载免费PDF全文
J A Dinsmoor 《Journal of the experimental analysis of behavior》2001,75(3):311-333
A molecular analysis based on the termination of stimuli that are positively correlated with shock and the production of stimuli that are negatively correlated with shock provides a parsimonious count for both traditional discrete-trial avoidance behavior and the data derived from more recent free-operant procedures. The necessary stimuli are provided by the intrinsic feedback generated by the subject's behavior, in addition to those presented by the experimenter. Moreover, all data compatible with the molar principle of shock-frequency reduction as reinforcement are also compatible with a delay-of-shock gradient, but some data compatible with the delay gradient are not compatible with frequency reduction. The delay gradient corresponds to functions relating magnitude of behavioral effect to the time between conditional and unconditional stimuli, the time between conditioned and primary reinforcers, and the time between responses and positive reinforcers. 相似文献

A community-based sample of disadvantaged African American women (n = 445) was recruited to participate in 1 of 3 theoretically driven experimental interventions based on either the theory of gender and power, social learning theory, or cognitive behavioral theory. Intervention outcomes were compared with a waiting list control condition. From baseline to postintervention, women in the experimental interventions showed differential change on cognitive indices (knowledge and attitudes) and skill acquisition (partner negotiation skills, correct condom application, lubricant selection, and information-provision to social networks) whereas control participants were unchanged. Women in the 3 experimental interventions also completed follow-up assessments for 1 year following the interventions. In all 3 experimental conditions, condom use increased relative to the control group and there were no differences between the experimental interventions. Women who participated in one of the theoretically grounded interventions continued to increase condom use over the following year. Women entering new relationships reported significantly more condom use than did women who remained in ongoing relationships. The findings suggest that intervention models that have proven effective for women who engage in high-risk behavior may be less effective for women in established relationships for whom risk is primarily derived from the extrarelationship behavior of their partners. 相似文献

The authors develop and evaluate an online networking intervention, Building Relationships and Improving Opportunities (BRIO), built in conjunction with the networking literature and social cognitive theory (Bandura, 1986, 1999). A field experiment using 491 unemployed job seekers shows that the intervention increases networking intensity, networking self-efficacy, and proximal networking benefits. Further, the intervention generates higher quality reemployment through its positive effects on networking self-efficacy. Individuals who completed the intervention and were also lower in extraversion showed the most positive improvements in networking self-efficacy and reemployment quality. The study advances the literature by uncovering the mechanisms through which a networking intervention may result in improved reemployment success, and demonstrating the moderating role of individual differences in affecting intervention outcomes. The study helps practice by providing a publicly available, research-based training to improve job search networking. 相似文献

Magnuson, McMurray, Tanenhaus, and Aslin [Cogn. Sci. 27 (2003) 285] suggest that they have evidence of lexical feedback in speech perception, and that this evidence thus challenges the purely feedforward Merge model [Behav. Brain Sci. 23 (2000) 299]. This evidence is open to an alternative explanation, however, one which preserves the assumption in Merge that there is no lexical–prelexical feedback during on‐line speech processing. This explanation invokes the distinction between perceptual processing that occurs in the short term, as an utterance is heard, and processing that occurs over the longer term, for perceptual learning. 相似文献
