ABSTRACTVirtual simulations allow users to feel and manipulate objects as they would in the physical world. Guided by exemplification theory and risk communication research, a virtual exemplar was developed to allow users to feel the weight of the caloric density of unhealthy snacks (e.g., potato chips) to heighten risk perceptions on snack choices. A 3 (base-rate statistics, print exemplar, virtual exemplar) × 3 (Time 1, Time 2, Time 3) mixed design experiment (N = 152) compared the effect of three mediated modes of delivering health information at baseline, immediately after, and 1 week after treatments. Virtual exemplars led to greater spatial presence, issue involvement, and recommended health behavior than did base-rate statistics or print exemplars, but had no effect on perceived vividness. Heightened perceived susceptibility following virtual exemplars persisted for 1 week. Findings emphasized the importance of spatial presence elicited by an exemplar in heightening the perceived susceptibility of health risks both immediately after and 1 week after exposure. The role of spatial presence and vividness in the context of virtual exemplars that afford the illusion of firsthand experiences is discussed and compared against traditional exemplification research that has focused on the impact of secondhand experiences. 相似文献

探讨情绪弹性和性别变量对青少年加工负性情绪信息时注意偏向的影响,采用情绪stroop实验范式,以46名青少年为被试,以负性情绪图片为实验材料,考察不同情绪弹性和性别的青少年在负性情绪图片颜色识别时的反应时间差异。结果发现,情绪弹性对负性情绪图片颜色识别的主效应显著,统计效力非常明显;性别对负性情绪图片颜色识别的主效应显著,统计效力明显;情绪弹性与性别在颜色识别上的交互作用不显著。这说明青少年负性情绪信息加工过程中产生的注意偏向效应受情绪弹性和性别因素的影响。 相似文献

In this study, we simulated environmental heat exposure to 18 participants, and obtained functional magnetic resonance image (fMRI) data during resting state. Brain functional networks were constructed over a wide range of sparsity threshold according to a prior atlas dividing the whole cerebrum into 90 regions. Results of graph theoretical approaches showed that although brain networks in both normal and hyperthermia conditions exhibited economical small-world property, significant alterations in both global and nodal network metrics were demonstrated during hyperthermia. Specifically, a lower clustering coefficient, maintained shortest path length, a lower small-worldness, a lower mean local efficiency were found, indicating a tendency shift to a randomized network. Additionally, significant alterations in nodal efficiency were found in bilateral gyrus rectus, bilateral parahippocampal gyrus, bilateral insula, right caudate nucleus, bilateral putamen, left temporal pole of middle temporal gyrus, right inferior temporal gyrus. In consideration of physiological system changes, we found that the alterations of normalized clustering coefficient, small-worldness, mean normalized local efficiency were significantly correlated with the rectal temperature alteration, but failed to obtain significant correlations with the weight loss. More importantly, behavioral attention network test (ANT) after MRI scanning showed that the ANT effects were altered and correlated with the alterations of some global metrics (normalized shortest path length and normalized global efficiency) and prefrontal nodal efficiency (right dorsolateral superior frontal gyrus, right middle frontal gyrus and left orbital inferior frontal gyrus), implying behavioral deficits in executive control effects and maintained alerting and orienting effects during passive hyperthermia. The present study provided the first evidence for human brain functional disorder during passive hyperthermia according to graph theoretical analysis using resting-state fMRI. 相似文献

人乳头瘤病毒疫苗的问世使宫颈癌的预防进入崭新的时代,自其问世以来便饱受伦理争议。通过分析目前全球医学文献中比较重视和争议的伦理问题,如Gardasil与Cervarix哪种更为有效,能否在发展中国家顺利推广,应当"强制接种"还是"自愿接种",男性是否应常规接种等。基于伦理学的基本原则,提出正确的宣教是解决的经由之路。 相似文献

This study investigated the cross‐cultural validation of the Chinese translation of the Counselor Burnout Inventory (CBI) with a sample of school counselors in Hong Kong. Specifically, this study examined the CBI's factor structure using confirmatory factor analysis and calculated the effect size, to compare burnout scores among the counselors of 4 countries (Hong Kong, Japan, South Korea, and the United States). Results indicated that a 5‐factor model was the most appropriate to accommodate the data. In addition, the results showed that the levels of Hong Kong counselors’ burnout were similar to those of U.S. counselors, but differed from counselors in Japan and South Korea. 相似文献

People infer traits from other people's behaviors without intention, awareness, or effort, and this spontaneous trait inference (STI) effect has been shown to be robust. The purpose of the present research was to demonstrate the flexibility of STIs despite the ubiquity. Specifically, we examined the effect of an affiliation goal on STI formation and found a positivity bias. In Experiment 1, perceivers with an affiliation goal formed more positive (versus negative) spontaneous trait inferences compared to those without this goal and those who had been primed with semantically positive, affiliation-unrelated words. Experiment 2 provided evidence that this effect was driven by a motivational state by showing that the positivity bias occurs only when a perceiver's goal to affiliate remains unfulfilled. The goal's interaction with trait valence showed focused, goal-relevant bias. These studies are the first to show that STIs form flexibly in response to perceivers' primed social goals supporting the functionality account of STIs in implicit impression formation. 相似文献

The purpose of this study is to investigate whether effective coping strategies play an important role to reduce burnout levels among sexual or substance abuse counselors. The authors examined whether coping strategies mediated or moderated relations between job stress and burnout in a sample of 232 abuse‐specific counselors. Results indicated that self‐distraction and behavior disengagement coping strategies mediated the relationships between 3 job stress variables (workload, role conflict, and job ambiguity) and burnout. Although venting and humor coping strategies positively moderated the relationship between role ambiguity and burnout, active coping strategies negatively moderated the relationship between workload and burnout. 相似文献

Using structural equation modeling, the authors investigated the mediators between stress and attitudes toward seeking professional help among 298 undergraduate students in South Korea. Results indicated that attachment styles (avoidance and anxiety) and stigma (public and self‐stigma) mediated the relationship between stress and attitudes toward seeking help. Furthermore, public and self‐stigma had different paths depending on attachment styles related to help seeking. Regarding previous counseling experience, differences in the relationships between stress, attachment styles, stigma, and attitudes toward seeking help were evident. 相似文献
