The discrimination of discrete and continuous amounts in African grey parrots (Psittacus erithacus)

A wealth of research in infants and animals demonstrates discrimination of quantities, in some cases nonverbal numerical perception, and even elementary calculation capacities. We investigated the ability of three African grey parrots (Psittacus erithacus) to select the largest amount of food between two sets, either discrete food items (experiment 1) or as volume of a food substance (experiment 2). The two amounts were presented simultaneously and were visible at the time of choice. Parrots were tested several times for all possible combinations between 1 and 5 seeds or 0.2 and 1 ml of food substance. In both conditions, subjects performed above chance for almost all combinations. Accuracy was negatively correlated with the ratio, that is performance improved with greater differences between amounts. Therefore, these results with both individual items and volume discrimination suggest that parrots use an analogue of magnitude, rather than object-file mechanisms to quantify items and substances.     

The others: Universals and cultural specificities in the perception of status and dominance from nonverbal behavior

The current study analyzes trans-cultural universalities and specificities in the recognition of status roles, dominance perception and social evaluation based on nonverbal cues. Using a novel methodology, which allowed to mask clues to ethnicity and cultural background of the agents, we compared impression of Germans, Americans and Arabs observing computer-animated interactions from the three countries. Only in the German stimulus sample the status roles (employee vs. supervisor) could be recognized above chance level. However we found significant correlations in dominance perception across all countries. Significant correlations were only found for evaluation between German observers and observers from the other two countries. Perceived dominance uniformly predicted the assignment of status-roles in all cultures. Microanalysis of movement behavior further revealed predictive value of specific nonverbal cues for dominance ratings. Results support the hypothesis of universalities in the processing of dominance cues and point to cultural specificities in evaluative responses to nonverbal behavior.     

Myopic perception of having a deadline in negotiations: An anchoring effect due to question order

In negotiations, people tend to perceive a deadline as more detrimental to themselves than to their opponents. This phenomenon is termed myopic perception. The present research proposes that myopic perception can be understood as a result of an anchoring effect due to the question order used in probing the perception of a deadline. When people estimate deal prices before rating the influence of a deadline, their judgements are anchored on their negotiation outcomes, making their perception egocentric, which leads to myopic perception. As a result, myopic perception was hypothesized to be reduced by reversing the above question order to change the respondents' judgement anchor from negotiation outcomes to negotiation procedures. In Study 1, myopic perception disappeared when participants rated the general influence of a deadline before estimating deal price in a negotiation scenario. In Study 2, pairs of participants negotiated under a tight deadline. Myopic perception of a deadline was manipulated before the negotiation. Dyads without myopic perception had a smaller discrepancy in reservation price. However, myopic perception had no effect on impasse rates or final deal prices. The results are discussed with respect to behavioural forecasting and practical implications of myopic perception.

'Rallying around the flag': Can an intergroup contact intervention promote national unity?

A longitudinal study evaluated the success of a contact-based nation-building intervention (the Malaysian National Service Programme) in promoting various facets of national unity. The study assessed how post-test measures of quality of intergroup contact, outgroup evaluations, and levels of identification changed compared to their respective pre-test levels, for both National Service and control group participants. The intervention did not lead to a worsening of any of the constructs related to intergroup relations, which is noteworthy given the novelty for many participants of mixing in a multi-ethnic setting. Furthermore, all rater groups (Malays, Chinese, and Indians) maintained their ethnic identity, even in the presence of high levels of national identity, which we discuss with respect to past research on the effects of positive intergroup contact on minority group identification. However, the changes associated with the intervention yielded only small effect sizes, and, on the whole, National Service participants did not show significantly greater improvement than that experienced by control participants. We discuss the value of intergroup contact in this novel setting, considering various features of this programme that may have limited its effectiveness and discuss how such interventions can more successfully meet their goals.     

Boys’ and Girls’ Relational and Physical Aggression in Nine Countries

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational and physical aggression in more diverse cultural contexts. This study examined the factor structure of, associations between, and gender differences in relational and physical aggression in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Children ages 7–10 years (N = 1,410) reported on their relationally and physically aggressive behavior. Relational and physical aggression shared a common factor structure across countries. In all nine countries, relational and physical aggression were significantly correlated (average r = .49). Countries differed in the mean levels of both relational and physical aggression that children reported using and with respect to whether children reported using more physical than relational aggression or more relational than physical aggression. Boys reported being more physically aggressive than girls across all nine countries; no consistent gender differences emerged in relational aggression. Despite mean‐level differences in relational and physical aggression across countries, the findings provided support for cross‐country similarities in associations between relational and physical aggression as well as links between gender and aggression.

社群、精神性传统和中国社会中的灾难(英文)

本文假定深切的处境观念和社群疗法是受害者"家庭"观念重建的最好途径。本文作者认真响应中国心理学会主席张侃的号召,重视中国的本土资源和精神遗产对于中国人在心理治疗中作用。本文沿袭了沃尔什将重建社群作为缓解创伤和灾难效果的四种方式:分享对创伤事件的认知,分享丧失和存活的经验,社群的重新组织和关系的重新建立。有人认为在灾难之后,精神性也可以在意义和社群的复原中扮演着积极的作用,前提是尊重信仰,鼓励信仰者使用自己的信仰语言,而不是把信仰当作工具来寻求心理健康。文中引用的例子包括俄罗斯乌克兰人中的门诺派教徒在社群/宗教重建中的努力,还有中国人对2008年5月12日汶川大地震中对灾难的回应方式。
