We examined how people use social and verbal cues of differing priorities in making social decisions. In Experiment 1, formally identical life – death choice problems were presented in different hypothetical group contexts and were phrased in either a positive or negative frame. The risk‐seeking choice became more dominant as the number of kin in an endangered group increased. Framing effects occurred only in a heterogeneous group context where the lives at risk were a mixture of kin and strangers. No framing effect was found when the same problem was presented in the context of a homogeneous group consisting of either all kin or all strangers. We viewed the framing effects to be a sign of indecisive risk preference due to the differential effects of a kinship cue and a stranger cue on choice. In Experiment 2, we presented the life – death problem in two artificial group contexts involving either 6 billion human lives or 6 billion extraterrestrial lives. A framing effect was found only in the human context. Two pre‐conditions of framing effects appear to be social unfamiliarity of a decision problem and aspiration level of a decision maker. In Experiment 3, we analyzed the direction of the framing effect by balancing the framing. The direction of the framing effect depended on the baseline level of risk preference determined by a specific decision context. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

This study set out to explore the trajectory of personal, moral and spiritual values of students taking Religious Studies at A level in the UK. A sample of 150 students completed a battery of measures at the beginning of their period of A level study and again at the end. The data found no difference over this period of time in personal values (purpose in life, self-esteem, and empathy) in some moral values (concerning anti-social behaviour and concerning substance use) and in levels of religious exclusivism or frequency of private prayer. The areas in which significant differences were observed were concerned with attitude toward sex and relationships, religious pluralism, belief in life after death, and mystical orientation. Between the ages of 16 and 18 years, following two years’ engagement with Religious Studies at A level, the participants became more liberal in their approach toward sex and relationships, less convinced about the truth claims of religious pluralism, less likely to adhere to traditional Christian teaching on life after death, and less open to mystical experience. They are also less certain of ever having had a religious experience, and less frequent in their practice of religious attendance.  相似文献

The ability to think abstractly constitutes a fundamental dimension of human cognition. Although abstraction has been extensively studied, its emotional and affective antecedents have been largely overlooked. One experiment was conducted to examine whether physical pain affects abstraction. Drawing on Construal Level Theory [Trope, Y., &; Liberman, N. (2010). Construal-level theory of psychological distance. Psychological Review, 117, 440–463] and Loewenstein’s [(1996). Out of control: Visceral influences on behavior. Organizational Behavior and Human Decision Processes, 65, 272–292] visceral factors theory, we hypothesised that pain impairs abstraction because pain constricts people’s mental horizons and lead to a concrete, inward-focus toward oneself in the here and now. Physical pain was manipulated between subjects (N?=?150). The participants either kept their left hand immersed in cold (painful) water or neutral (painless) water while we measured abstract versus concrete behaviour identification, categorisation, and perceptual processing. Bayesian statistical analyses indicate substantial evidence against the hypothesis that pain impairs abstraction. In contrast to many other previously studied cognitive outcomes (e.g. attention), abstraction appears to be largely immune to acute, experimentally induced pain.  相似文献

Warning signs are the most effective way to alert people to hazards in the industries, architecture, and transportation. To better understand how these warning signs prompted hazard, this study investigated the intrinsic mechanism of hazard perception of warning signs, including warning words (low versus high hazard levels) and surrounding shapes (upright triangle versus circle). We recruited 18 participants and recorded electroencephalogram (EEG). We found that a combination of high-hazard-level words and an upright triangle shape significantly elicited more negative N300 and increased theta-band (3–8 Hz) synchronization, but reduced beta-band (15–30 Hz) desynchronization. The N300 component represented the emotional arousal strength, theta oscillations reflected the engagement of retrieval of emotional experiences from episodic memory, and beta oscillation connoted the semantic encoding. Thus, these findings suggested that a high-hazard-level combination had the ability to obtain high priority in cognitive processing. The EEG pattern changes allowed us to assess whether the hazard perception of warning signs was high or low, which could be an accurate indicator to better evaluate the design of warning signs.  相似文献

This study intended to (1) investigate the pedestrian injury severity involved in traffic crashes; and (2) address the spatial and temporal heterogeneity simultaneously. To achieve the objectives, geographically and temporally weighted regression (GTWR) model was proposed to deal with both spatial and temporal heterogeneity simultaneously. The pedestrian crash data of Hong Kong metropolitan area from 2008 to 2012 were collected, involving 1652 pedestrian-related injury samples. By comparing GTWR model and standard geographically weighted regression (GWR) model and temporally weighted regression (TWR) model, the proposed GTWR model showed potential benefits in modeling both spatial and temporal non-stationarity simultaneously in terms of goodness-of-fit and F statistics. Results revealed that number of vehicles, number of pedestrian-related casualties, speed limit, vehicle movement and injury location have significant influence on pedestrian injury severity in different areas. The conclusions are reached that GRWR model can address the relationship between pedestrian injury severities and influencing factors, as well as accommodating spatial and temporal heterogeneity simultaneously. The findings provide useful insights for practitioners and policy makers to improve pedestrian safety.  相似文献

Research on Tip of the Tongue (ToT) states has been used to determine whether access to syntactic information precedes access to phonological information. This paper argues that previous studies have used insufficient analyses when investigating the nature of seriality of access. In the first part of this paper, these complex issues are discussed and suitable analyses proposed. In the second part, new experimental data are presented. In Experiment 1, English speakers were asked to give information about mass/count status and initial phoneme of nouns, when in a ToT state. In Experiment 2, German speakers were asked to report grammatical gender and initial phoneme of nouns, when in a ToT state. Evidence that syntactic and phonological information are accessed independently was obtained for both languages. Implications for models of language production and further methodological issues in ToT research are discussed.  相似文献

The primary aim of this study was to measure psychological distress, pain severity, health related quality of life (QOL) and pain coping strategies in patients with irritable bowel syndrome (IBS) and ulcerative colitis (UC). A second aim was to determine the influence of somatic and psychological variables on health related QOL. Eighty-eight IBS and 66 UC patients completed the Irritable Bowel Syndrome Quality of Life Questionnaire (IBSQOL), Pain Severity Scale of West Haven Yale Multidimensional Pain Inventory (WHYMPY), Symptom Checklist-90-R (SCL-90-R) and Coping Strategies Questionnaire (CSQ). T-tests and GLM Analysis of Covariance were used for statistical analysis. IBS patients had significantly higher levels of psychological distress, pain severity and maladaptive pain coping strategies (catastrophization), and lower QOL than UC patients. Variance of QOL in IBS was explained for the most part by catastrophization (15%), then by psychological distress (8%), and for the less part by pain severity (5%). In UC, pain severity explained 21%, psychological distress 8%, and catastrophization 3% of the variance of QOL. These results suggest there are differences between IBS and UC patients in the role of physical and psychological factors in QOL and emphasize the importance of cognitive processes in IBS.  相似文献

变量的潜在结构是连续的还是分类的不应被随意指定,错误的设定可能导致不正确的结论。本研究的目的在于从实证的角度探索网络成瘾的潜在结构。研究采用了来自中国杭州的2511名初中生对Young网络成瘾量表的有效作答数据,比较了Rasch模型、潜在类别模型和混合Rasch模型与数据的拟合情况。结果表明:2个潜在类别的混合Rasch模型可以最好地反映网络成瘾的潜在结构,说明网络成瘾包含两个存在着质的差异的群体,并且每个群体内的个体间存在量的差异。研究进一步比较了基于混合Rasch模型的分类与传统划界分数分类的区别,结果表明:Young的网络成瘾标准可能具有很小的误判率和较高的漏判率;基于Young网络成瘾测验的修订需要考虑有针对性地增加部分题目。  相似文献
