Intention-based evaluations of distributive actions by 4-month-olds

Four-month-olds’ ability to consider the intentions of agents performing distributive actions was investigated in four experiments, using the Violation of Expectation paradigm (VoE) (Experiments 1–3) and the Preferential Looking paradigm (Experiment 4). In Experiment 1, infants were presented with two events showing two types of failed attempts to perform a distribution. In an attempt to distribute fairly, the distributor first tried to reach one of the recipients to deliver an apple, he failed, and then attempted to reach the other recipient to deliver a second apple and also failed. In an attempt to distribute unfairly, a different distributor tried unsuccessfully to bring resources always to the same recipient. Infants looked reliably longer at failed fair distribution events, suggesting that they did not just react to the actions outcomes and they attended to agents' intentions. Experiments 2 and 3 assessed alternative explanations based on perceptual factors or affiliative behaviors. In Experiment 4, during the test trials, infants were shown both distributors simultaneously and they preferred to look at the fair rather than at the unfair distributor. Overall, these findings reveal an early ability to take into account distributors’ intentions and a preference for watching agents that tried to distribute resources fairly.     

人际愤怒的利与弊：来自元分析的证据

愤怒是因愿望落空、目标受挫或边界被犯而产生的负性情绪, 指向他人的愤怒即为人际愤怒。人际愤怒对接收者的影响有争议, 有人认为人际愤怒弊端极大, 有人认为人际愤怒是可资利用的工具。这种分歧可能源于评价指标、参照对象和应用场景的不同, 有必要用元分析系统考察人际愤怒的利与弊。本研究对67篇文献, 总样本量为15462人的185个效应值进行了分析, 结果发现：人际愤怒会让接收者让步更多、亲社会行为减少、问题解决行为提升, 同时情境不公平感增加, 对愤怒表达者的态度和能力评价均降低, 这些效应受接收者文化背景和相对权力大小的调节。这提示人际愤怒利弊相依, 能改变愤怒接收者的某些行为, 却增加对表达者的消极评价, 应视情景谨慎使用。     

Evaluating Multiple-Attribute Decision Support Systems

Differences in the perceived usefulness of five multiple-attribute decision support systems versus a basic spreadsheet are empirically assessed. Twenty-four college faculty members participated in a repeated measures experiment in which they used decision support software for personal computers to analyse semistructured multiple-attribute problems. The software packages employed were Criterium, Expert Choice, Logical Decision, VIMDA, VISA and the spreadsheet package Quattro Pro. A questionnaire was developed to assess user-friendliness of the software, confidence in the procedure implemented by the software, and users’ confidence in their results when employing the decision aids. Time to reach a decision was also measured. Significant differences were fund in the overall way users ranked these aids, in the perceived user-friendliness and the confidence in procedure among aids, and in the time it took to arrive at a result. Comments from users are also reported. © 1997 John Wiley & Sons, Ltd.     

Evaluating the desirability of meals: an illustrative multiattribute decision analysis procedure to assess portfolios with interdependent items

This paper presents an exploratory study designed to address complex scaling problems in applying value/utility theory to measuring preferences over alternative combinations (or portfolios) of multiattributed items. This application considers meals served to nursing home residents as portfolios of food items and seeks to maximize meal appeal. We consider food interrelation and link single food measurements to overall meal measurements in the process of constructing meal desirability scales. We test the resulting scales to capture one expert's professional judgments and discuss issues raised in this specific application in the context of general portfolio evaluation problems. © 1998 John Wiley & Sons, Ltd.     

The significance of blushing for fair- and dark-skinned people

Since blushing is difficult to detect in people with dark skin, their experience of blushing may differ fundamentally from people with fair skin. To investigate this issue, cheek temperature and forehead blood flow were measured in 16 Caucasians and 16 Indians during mental arithmetic and singing. Caucasians (particularly females) thought that they blushed more intensely than Indians, and also reported greater self-consciousness when singing. Vascular responses did not differ between groups. However, skin tone moderated the association between vascular responses and ratings of self-consciousness, blushing intensity, blushing propensity and fear of negative evaluation. These findings support the notion that the visibility of blushing influences the nature of emotions experienced in embarrassing social encounters.     

大学生社交焦虑成因的研究

探讨大学生社交焦虑的形成原因 ,为临床治疗提供理论基础。方法 :采用社交焦虑量表(IAS) ,个人评价问卷 (PEI) ,自编社交技能和他信问卷对 194名大学生被试进行测试。用SPSS7.0作回归、相关等统计分析。结果 :以自我评价、他信、社交技能为自变量 ,社交焦虑为因变量进行逐步回归分析 ,进入方程的变量为自我评价和社交技能。贡献量分别为 0 .32 7和 0 .0 4 0。以自我评价的 5个子维度 (学业、外貌、爱情、社会交往、与人们谈话 )、社交技能为自变量 ,社交焦虑为因变量进行逐步回归 ,进入回归方程的变量为“与人们交谈”因子、“社会交往”因子和社交技能 ,贡献量分别为 0 .2 96 ,0 .0 71和 0 .0 30。结论 :自我评价和社交技能是造成社交焦虑的重要原因 ,自我评价中的“与人们交谈”和“社会交往”方面是成因中的重要一环     

Presence of administrators differentially impacts eyewitness discriminability for same- and other-race identifications

Best practice guidelines recommend that eyewitness lineup administrators be blind to a suspect's identity, but no research has investigated whether the mere presence of a lineup administrator impacts eyewitness identification decisions. Informed by social facilitation theory, we predicted that the presence of an audience would differentially impact identification accuracy for same- and other-race identifications. Participants (N = 191) viewed same- and other-race lineups either with an audience or alone. Although the presence of an audience did not directly impact identification accuracy, significant indirect effects indicated that the audience provoked evaluation apprehension which hindered other-race identification accuracy and improved same-race identification accuracy. We suggest that using double-blind lineup procedures may not sufficiently protect eyewitness identification accuracy when making other-race lineup decisions in the presence of others.     

Whole of community suicide prevention forums for Aboriginal Australians

It is well known that Aboriginal Australians are at increased risk of suicide. Contributors to suicide differ for Indigenous and non-Indigenous populations (Westerman, 2003; 2019). This study evaluated whole of community suicide prevention forums conducted across six locations. Attendees were youth (N = 136), service providers (N = 225), and community members (N = 158). The content of the forums was empirically based and, for service providers and community members, covered knowledge of suicide, and depression specific to Aboriginal people, skills relating to working with depressed and suicidal Aboriginal people, and intentions to help an Aboriginal person who is suicidal. Content for youth attendees focused on knowledge of suicide and depression, coping skills, intentions to help a friend, and beliefs about suicide. While the results demonstrated significant gains across most domains, there was a potentiating effect with some skills increases becoming more significant over each phase. This demonstrates that a whole of community approach to Indigenous suicide prevention is required, and that clinical and cultural skills require a longer-term approach for impact and sustainability.
