How do changes in choice-set size influence information search and subsequent decisions? Moreover, does information overload influence information processing with larger choice sets? We investigated these questions by letting people freely explore sets of gambles before choosing one of them, with the choice sets either increasing or decreasing in number for each participant (from two to 32 gambles). Set size influenced information search, with participants taking more samples overall, but sampling a smaller proportion of gambles and taking fewer samples per gamble, when set sizes were larger. The order of choice sets also influenced search, with participants sampling from more gambles and taking more samples overall if they started with smaller as opposed to larger choice sets. Inconsistent with information overload, information processing appeared consistent across set sizes and choice order conditions, reliably favoring gambles with higher sample means. Despite the lack of evidence for information overload, changes in information search did lead to systematic changes in choice: People who started with smaller choice sets were more likely to choose gambles with the highest expected values, but only for small set sizes. For large set sizes, the increase in total samples increased the likelihood of encountering rare events at the same time that the reduction in samples per gamble amplified the effect of these rare events when they occurred—what we call search-amplified risk. This led to riskier choices for individuals whose choices most closely followed the sample mean. 相似文献

Abstract This study was aimed at developing a measure of Kelly's concept of dispersion of dependency and providing evidence for its usefulness in differentiating degree of dispersion of dependency. Smith and Grassle's (1977) adaptation of Hurlbert's diversity index, a measure used by biologists to differentiate degrees of species diversity, was applied to dependency grids, specifically “being helped” grids. The diversity index was shown to be both useful in differentiating prototypes of relatively dispersed and undispersed grids and robust. Furthermore, evidence was provided for its predictive validity using predictions made by Kelly concerning dependency construing associated with differences in dispersion of dependency. Greater dispersion of dependency was related to making more discriminations about dependencies, and undispersed dependency was related to relatively impermeable and preemptive construing. Thus the measure was shown to be satisfactory for identifying dispersion of dependency, such that, used in this context, it could be aptly renamed the dispersion of dependency index. 相似文献

Previous research suggests that child maltreatment is transmitted across familial generations. However, extant studies focused exclusively on single maltreatment subtypes, instead of the more common experience of multitype maltreatment. This limitation is addressed in the first known study to examine the maternal intergenerational transmission of childhood multitype maltreatment among 104 mothers and their children. Findings demonstrated that mothers' childhood multitype maltreatment directly predicted their children's multitype maltreatment, instead of having indirect effects through maternal romantic attachment dimension, intimate partner violence, and psychological distress. Mothers' childhood multitype maltreatment was also related to intimate partner violence and anxious romantic attachment but unrelated to psychological distress. Our findings highlight the need for clinical attention to the long-term generational effects of diverse childhood traumas. 相似文献

Exemplification can be found in ontologies from the ancient world, such as those of Plato and Aristotle, and more recent ontologies, in particular those that take what exists to be determined by the empiricist’s Principle of Acquaintance. This study examines some of the ways in which exemplification takes different forms in these different ontologies. Exemplification has also been criticized as an ontological category. This paper examines a number of these criticisms, to see the extent to which they are viable. 相似文献

Face adaptation has been used as a tool to probe our representations for facial identity. It has also been claimed to play a functional role in face processing, perhaps calibrating the visual system towards encountered faces. However, for this to be so, face aftereffects must be observable following adaptation to ecologically valid moving stimuli, not just after prolonged viewing of static images. We adapted our participants to videos, static image sequences or single images of the faces of lecturers who were personally familiar to them. All three stimulus types produced significant, and equivalent, face identity aftereffects, demonstrating that aftereffects are not confined to static images but can occur after exposure to more naturalistic stimuli. It is also further evidence against explanations of face adaptation effects solely in terms of low-level visual processing. 相似文献

This study examines the discriminant validity of the Francis Attitude towards Christianity Scale with respect to the extrinsic, intrinsic and quest orientations of the Religious Life Inventory, among a sample of 400 British students. It was concluded that the attitude scale is a selective measure of intrinsic orientation and that previously reported associations with extrinsic religiosity and quest can be explained by intercorrelations among the three orientations included in the Religious Life Inventory. 相似文献

A multiple regression analysis was used to determine the susceptibility of the 16 Personality Factor Test (16PF) to faking for a sample of male felons. The study is a replication of an earlier study of a similar sample. Motivational distortion (MID) correlated significantly with the 16 PF primary scores. The relationship was most evident when the structure coefficients rather than the beta weights were analyzed. The findings were consistent with the previous results which indicated a fairly high degree of support for the MD corrections provided in the manual. An important exception was that Dominance (E) was suppressed by individuals from both samples when MD was present. 相似文献

This study explored the psychosocial mechanisms of change associated with differences in levels and linear change of adolescents' global life satisfaction across a 2-year time period. Based on a theoretical model proposed by Evans (1994), this study tested the relations between selected personality (i.e., extraversion and neuroticism) and environmental (stressful life events) variables and global life satisfaction when mediated by internalizing and externalizing problems. The results suggested support for internalizing problems as a mediator of the relationship of personality and environmental variables with life satisfaction. Pathways mediated by internalizing problems significantly predicted levels and linear change of life satisfaction across a 2-year time span. Furthermore, pathways mediated by externalizing problems significantly predicted the level but not the linear change of life satisfaction. Thus, behavior problems and their antecedents appear to relate significantly to adolescents' perceptions of their quality of life. Implications for adolescent mental health promotion were discussed. 相似文献

This study contrasted two models of prospective remembering: i.e., remembering in the future to perform an action that has been planned. High anxiety or discomfort is predicted by the first model to be associated with forgetting, and by the second model to be associated with remembering but not performing. Questionnaire data from 73 male and female college students support the second model (p < .01). For planned actions that were forgotten, there was an inverse relationship between importance and comfortableness (p < .01). Prospective remembering may be facilitated by reducing potential conflict between the importance and comfortableness of a planned action, involving other persons, and utilizing external retrieval cues. 相似文献

Emotional facial expressions are powerful social cues. Here we investigated how emotional expression affects the interpretation of eye gaze direction. Fifty-two observers judged where faces were looking by moving a slider on a measuring bar to the respective position. The faces displayed either an angry, happy, fearful or a neutral expression and were looking either straight at the observer, or were rotated 2°, 4°, 6° or 8° to the left and right. We found that happy faces were interpreted as directed closer to the observer, while fearful and angry faces were interpreted as directed further away. Judgments were most accurate for neutral faces, followed by happy, angry and fearful faces. These findings are discussed on the background of the “self-referential positivity bias”, suggesting that happy faces are preferably interpreted as directed towards the self while negative emotions are interpreted as directed further away. 相似文献
