This paper introduces a new model to explain perceptions of unfairness in resource allocations between multiple recipients. The model yields several novel predictions, all confirmed in a series of new empirical tests. For instance, while much prior research focuses on the differences between the judge’s share and others’ shares, we argue that people also care about differences between others’ shares. In particular, the presence of a single loser increases perceptions of unfairness. We also study individual variation in sensitivity to the single-loser dimension. Most centrally, we offer empirical support for the existence – indeed the prevalence – of ostraphobics, individuals with an acute sensitivity to being “ostracized” as a sole loser. We show that ostraphobics perceive unfairness more strongly than other types, are higher in need to belong and fear of negative evaluation, and are more prone to a heretofore unrecognized type of preference reversal with respect to fairness.  相似文献

The main aim of this study was to provide a detailed examination of the nature of the messages that adolescent boys and girls receive about their bodies. Forty adolescent boys and 40 adolescent girls participated in an in-depth interview to gain an understanding of the range of potential ‘sources’ of body-related messages. Messages were organized around the source of these messages (self, mother, father, brother, sister, female friends, male friends, media). There were consistent gender differences in the way that adolescents received and interpreted messages about their bodies. Overall girls received more positive and more negative messages than boys did. Boys reported having received virtually no negative messages from most people. The content of internal dialogue among adolescents revealed that messages about the body could be interpreted, distorted, and deflected. The implications of these findings for preventing body image-related problems and disordered eating among adolescents are discussed.  相似文献

本研究采用中国运动员赢分和输分后的表情, 通过行为学和脑电技术比较面孔表情和身体姿势的加工机制。实验1探讨了赢分与输分面孔和身体的效价和强度, 实验2考察了图片的情绪类型(中性、快乐、悲伤、愤怒、恐惧、厌恶), 实验3采用脑电技术比较了赢分和输分情绪的神经机制。3个实验的行为结果表明, 相比面孔, 身体信息更能区分赢分和输分的效价, 而且身体姿势传递的情绪内容相对单一, 面孔表情传递的情绪内容相对复杂和多样化。脑电实验的结果表明, 身体的情绪信息能更早地被大脑识别, 表现在N170成分上, 面孔表情的情绪效应, 反映在EPN成分上。在加工的晚期, 面孔和身体条件下, 均观测到胜利比失败表情诱发了更大的LPP成分。结果表明, 大脑在多个阶段对身体姿势进行情绪评估与分类, 为行为上身体对效价的高区分性提供了证据。  相似文献

Using regional cerebral blood flow as an index of cerebral activity we studied dyslexic and control subjects during simple word reading tasks. The groups were pre-tested for reading skill and the dyslexic group had a lower reading performance but could read and comprehend standard texts. The aim was to elucidate differences in the cerebral activation pattern during reading. The tasks were simple enough that performance differences between the groups could be excluded. We found specific differences between the two groups that were dependent on the language task. When the visual route for language information was used, minor qualitative differences were found between the groups pertaining to the dominant hemisphere. Increasing the complexity of the task by using pseudowords activated the left frontal region more in the dyslexic group than in the control group. A similar effect was seen in a minor region in extrastriate lateral occipital cortex (BA 19). This finding indicates that the dyslexics used areas in these regions that the controls did not. On the other hand, the dyslexics activated less in the right angular gyrus, right dorsolateral prefrontal cortex, and in the right pallidum. Reading skill correlated with the level of activity in the right frontal cortex. We conclude, that cerebral activation pattern elicited by reading is different in dyslexics compared to controls in spite of an almost complete functional compensation.  相似文献

Despite their elevated risk of health problems and a propensity to be more overweight or underweight relative to the other members of the Australian population, there has been no previous investigation of body image concerns among Indigenous Australians. In this study we investigated the level of body image importance and body image dissatisfaction among 19 rural Indigenous adolescents (7 males, 12 females) and 28 urban Indigenous adolescents (15 males and 13 females). Our hypotheses that there would be gender differences in body image importance and body image satisfaction were not generally supported. However, males placed more importance on muscle size and strength than females, and rural participants placed more importance on weight than urban participants. Comparison to existing data obtained from Caucasian adolescents suggested that Indigenous youth may be less concerned and dissatisfied with body weight and shape. These results are discussed in relation to findings from studies of non-Indigenous adolescents, and Indigenous health issues. The limitations of the current study and the need for further studies are also discussed.  相似文献

The sound pressure level of vowels reflects several nonlinguistic and linguistic factors: distance from the speaker, vocal effort, and vowel quality. Increased vocal effort also involves the emphasis of higher frequency components and increases in F0 and F1. This should allow listeners to distinguish it from decreased distance, which does not have these additional effects. It is shown that listeners succeed in doing so on the basis of single vowels if phonated, but not if whispered, and that they compensate for most of the between-vowel variation in level. The results obtained when listeners had to estimate vocal effort as well as distance suggest that an analysis of an utterance takes place at an early stage in auditory processing, before memories of episodes are stored.  相似文献

To describe the development of words and sentences in Swedish children 16-28 months old, 900 parental reports on 336 children were analyzed. Subjects were randomly selected from the national birth register, and there was a response rate of 88%. The assessments were made using the Swedish Early Communicative Development Inventory--words and sentences (SECDI--w&s). Age-based norms for productive vocabulary, pragmatic skills, grammar skills, and maximum length of utterance (MaxLU) were determined. We describe the development of feedback morphemes, semantic categories, and single words and tasks. Correlation across measures was significant, and especially strong between vocabulary size and grammar skills. Optimized positive predictive values were high for 25 to 28 month predictions (71%-88%), and vocabulary scores were found to be of particular predictive importance. No significant gender differences were detected. The clinical relevance of the instrument is discussed.  相似文献
