The notion that consumers' preference is constructed by decision context is well established. Two of such salient manifestations are compromise effect and attraction effect. Although literature has explored the moderators of these effects from the perspective of a decision maker, little is known about whether a significant difference exists between the effects of individual differences as a situational state and as a stable personality. This article approaches this question by examining how specific self‐confidence and general self‐confidence shape consumer's preference for context options. Four studies find that compromise effect is greater for consumer with high specific self‐confidence, whereas attraction effect is greater for consumer with low specific self‐confidence. The two context effects are greater for consumers with low general self‐confidence only in the presence of social influence. In addition, low (vs. high) general self‐confidence strengthens (vs. weakens) the impact of specific self‐confidence on context effects under this condition. This article concludes by discussing the theoretical and practical implications of the findings. 相似文献

Three studies investigate the impact of effortful constructive processing on framing effects. The results replicated previous findings: Participants avoided the risky option when the scenario was framed in terms of gains, but preferred this option when the scenario was framed in terms of losses. Importantly, framing effects were most pronounced when conditions allowed for an effortful constructive processing style (i.e., substantive processing). This impact of decision frames varied when decision time served as an indicator for the elaboration extent (Study 1), and also when processing motivation (accountability; Study 2) and processing ability (decision time; Study 3) were manipulated. Moreover, effortful processing did not increase framing effects when contextual cues reduced the necessity for constructive thinking (Study 1). We suggest that decision frames may take on very different roles as a function of the ambiguity of the decision problem, and the degree and style of processing.

Outcome measurement in clinical genetics is challenging. Outcome attributes used currently have been developed by service
providers or adapted from measures used in other areas of healthcare. Many of the ‘patients’ in clinical genetics are healthy
but at risk of developing or transmitting a condition. Usually no pharmacological or surgical treatment is offered, although
information-giving is an objective of most consultations. We argue that services should be evaluated on the basis of how well
they alleviate the effects of disease, from a patient perspective. This paper describes a qualitative study using seven focus
groups with health professionals, patients and patient representatives. Social and emotional effects of genetics diseases
were identified. Some differences emerged between the effects identified by health professionals and those identified by patients.
These findings will be used to inform the evaluation of existing outcome measures and develop robust measures of outcome for
clinical genetics services. 相似文献

本研究考察中文聋生读者利用语境预测性信息促进词汇加工的过程特点。实验采用3(组别:高阅读技能聋生组vs.高阅读技能聋生的能力匹配健听组vs.低阅读技能聋生组)×2(句子背景对目标词的预测程度:高预测vs.低预测)混合设计。结果发现:(1)目标词的左侧词汇上,能力匹配健听组在凝视时间和总注视时间两个指标上可见语境预测性效应,两个聋生组在任何指标上均没有语境预测性效应;(2)目标词上,能力匹配健听组在首次注视时间、凝视时间和总注视时间三项指标上均可见显著的语境预测性效应,高阅读技能聋生组仅在总注视上可见语境预测性效应,低阅读技能聋生的任何眼动指标均没有语境预测性效应。由此可见,聋生在利用语境预测性促进词汇加工方面与健听读者有所差异;相对于低阅读技能聋生,高阅读技能聋生读者识别词汇时能更多地利用语境预测性信息。 相似文献

The Effects of Social Capital and Neighborhood Characteristics on Intimate Partner Violence: A Consideration of Social Resources and Risks 下载免费PDF全文

Intimate partner violence (IPV) is a growing public health problem, and gaps exist in knowledge with respect to appropriate prevention and treatment strategies. A growing body of research evidence suggests that beyond individual factors (e.g., socio‐economic status, psychological processes, substance abuse problems), neighborhood characteristics, such as neighborhood economic disadvantage, high crime rates, high unemployment and social disorder, are associated with increased risk for IPV. However, existing research in this area has focused primarily on risk factors inherent in neighborhoods, and has failed to adequately examine resources within social networks and neighborhoods that may buffer or prevent the occurrence of IPV. This study examines the effects of neighborhood characteristics, such as economic disadvantage and disorder, and individual and neighborhood resources, such as social capital, on IPV among a representative sample of 2412 residents of Toronto, Ontario, Canada. Using a population based sample of 2412 randomly selected Toronto adults with comprehensive neighborhood level data on a broad set of characteristics, we conducted multi‐level modeling to examine the effects of individual‐ and neighborhood‐level effects on IPV outcomes. We also examined protective factors through a comprehensive operationalization of the concept of social capital, involving neighborhood collective efficacy, community group participation, social network structure and social support. Findings show that residents who were involved in one or more community groups in the last 12 months and had high perceived neighborhood problems were more likely to have experienced physical IPV. Residents who had high perceived social support and low perceived neighborhood problems were less likely to experience non‐physical IPV. These relationships did not differ by neighborhood income or gender. Findings suggest interesting contextual effects of social capital on IPV. Consistent with previous research, higher levels of perceived neighborhood problems can reflect disadvantaged environments that are more challenged in promoting health and regulating disorder, and can create stressors in which IPV is more likely to occur. Such analyses will be helpful to further understanding of the complex, multi‐level pathways related to IPV and to inform the development of effective programs and policies with which to address and prevent this serious public health issue. 相似文献

目的:比较汉词与图画材料再认过程中的事件相关电位(ERP)表现并探讨其脑机制。方法:使用经典“学习一再认”实验模式对21名大学生进行测验,同时记录EEG,离线处理后对汉词及图画再认诱发的ERP波形主要成分及新旧效应进行比较。结果:两种材料的再认均诱发出了明显的新旧效应。顶区新旧效应头皮分布基本一致,但图画再认该效应波幅大于汉词再认;两种材料诱发的额区新旧效应有所不同,图画再认该效应为正走向,而汉词再认此效应表现为负走向趋势。结论:汉词与图画再认既存在某种共同的神经加工机制,叉分别涉及一些特异性的神经活动模式。 相似文献

位置和内容对网页广告效果影响的眼动评估 总被引:13,自引:0,他引:13
使用TobiiT120型眼动仪,以16名大学生为被试,记录他们阅读嵌有网页广告新闻网页时的眼动注视过程,以探讨广告呈现位置、新闻内容与网页广告的相关性是否影响人们对网页广告的注视。实验采用3(广告位置:上方、中间、下方)×2(相关性:相关、不相关)两因素被试内设计。结果发现:(1)新闻内容和网页广告的相关性不影响人们对网页广告的加工;(2)对位于新闻上方和新闻中间的网页广告,被试的注视次数较多,且注视时间较长;(3)对位于新闻中间的网页广告,其再认效果优于位于新闻上方和新闻下方的广告。表明只有网页广告呈现位置这一因素影响被试对网页广告的注视。 相似文献

Using the rich data set of the German Socio-Economic Panel (GSOEP) this article analyzes the effects of job characteristics on job satisfaction as well as the conditions under which low job satisfaction leads to job search, and under which job search leads to job changes. Individual fixed effects are included into the analysis in order to hold unobserved heterogeneity constant. According to the empirical results, the strongest determinants of job satisfaction are relations with colleagues and supervisors, task diversity and job security. Furthermore, job satisfaction is an important determinant of the self-reported probability of job search, which in turn effectively predicts actual job changes. The effect of job search on the probability of changing jobs varies with job satisfaction and is strongest at low levels of job satisfaction. The effects of job dissatisfaction on job search and of job search on quits are stronger for workers with lower tenure, better educated workers, workers in the private sector and when the economy and labor market are in a good condition. 相似文献
