Attributionally more complex people show less punitiveness and racism

Based on past findings that attributionally more complex people make less fundamental attribution error, it was hypothesized that they would show less punitiveness and racism. In a study of 102 undergraduates, this hypothesis received robust support. The effect of attributional complexity was significant in two different punitiveness measures, a rehabilitation support measure, and two different racism measures. Also, this effect still held when demographic variables, crime victimization history, and need for cognition were statistically controlled. Moreover, attributional complexity mediated the effect of need for cognition and gender on punitiveness and racism. Theoretical implications are discussed.     

健康行动过程取向模型的发展与前景

健康行动过程取向(HAPA)模型的提出源于健康行为社会认知模型的发展和Bandura社会认知理论的应用。在HAPA中, 健康行为变化被视为一个包括行为产生、保持和恢复在内的连续过程; 结果预期、危险感知、三种自我效能感和两类计划被用来解释意图的形成及其向行动的转化; 两个阶段的划分有助于区分三类干预对象, 建议实施菜单式干预。HAPA模型具有明显的理论优势, 也引发了有关模型实质的争论。当前和未来的研究旨在考察更多的自我调节变量、检验因果模型, 在健康行为的多个领域开展应用和干预研究。     

爱荷华博弈任务(IGT)与决策的认知神经机制

爱荷华博弈任务(IGT)是一项检查情感性决策机制的常用实验范式。据此, Damasio等人提出了躯体标记假设(SMH)解释情绪影响决策的神经生理机制。近期, 大量研究在IGT究竟是模糊决策还是风险决策、与情绪和认知的关系、与工作记忆和陈述性记忆的关系以及IGT的神经网络与分子遗传机制等方面积累了丰富资料。结果显示, IGT加工的早期由模糊决策主导, 情绪性躯体信号对引导决策选项的偏好可能起关键作用, 后期则倾向是一种风险决策, 认知评价和预期对选项偏向逐渐占优势; IGT与工作记忆的加工成分有相互重叠, 也需陈述性记忆的参与; IGT的加工不仅依赖于杏仁核、腹内侧前额皮层、眶额皮层等组成的情绪脑网络的活动, 还与背外侧前额皮层、海马、腹侧纹状体、岛叶皮层、辅助运动前区、扣带回皮层等许多脑区的活动有关; COMT和5-HTT的基因多态性会调节IGT相关的决策加工。总之, IGT是一项需要多重神经系统协同活动的决策加工任务, 且模糊与风险决策可能具有不同的遗传基础。     

CPM领导行为模式对员工利他行为及工作投入的作用机制

通过对我国26个省市企事业单位员工的问卷调查,探讨了CPM领导行为模式对员工利他行为和工作投入的影响途径。采用潜变量路径分析的方法,对两个阶段的模型进行检验和比较,结果表明：（1）C因素和M因素通过信任上司的完全中介作用影响利他行为和工作投入,而P因素则通过信任上司的部分中介作用对它们产生影响。（2）信任上司通过情感承诺的完全中介作用影响工作投入,通过情感承诺的部分中介作用影响员工的利他行为。     

Determining who owns what: do children infer ownership from first possession?

A basic problem of daily life is determining who owns what. One way that people may solve this problem is by relying on a ‘first possession’ heuristic, according to which the first person who possesses an object is its owner, even if others subsequently possess the object. We investigated preschoolers’ use of this heuristic in five experiments. In Experiments 1 and 2, 3- and 4-year-olds inferred that an object was owned by the character who possessed it first, even though another character subsequently possessed it. Two-year-olds also showed this bias, but only when the object was placed between the characters when children were asked about ownership. Experiment 3 ruled out the possibility that children’s bias to select the first possessor results from a tendency to select the character first associated with the object. Experiment 4 showed that 3- and 4-year-olds have difficulty disregarding the first possession heuristic, even when provided with evidence that the character who first possessed an object is not its owner. But Experiment 5 found that children can disregard the heuristic in at least some situations. These five experiments suggest that the first possession heuristic guides children’s ownership inferences. The findings provide the first evidence that preschoolers can infer who owns what, when not explicitly told, and when not reasoning about objects with which they are personally acquainted.     

Young infants' actions reveal their developing knowledge of support variables: converging evidence for violation-of-expectation findings

Violation-of-expectation (VOE) tasks have revealed substantial developments in young infants' knowledge about support events: by 5.5 months, infants expect an object to fall when released against but not on a surface; and by 6.5 months, infants expect an object to fall when released with 15% but not 100% of its bottom on a surface. Here we investigated whether action tasks would reveal the same developmental pattern. Consistent with VOE reports, 5.5- and 6.5-month-old infants were more likely to reach for a toy that rested on as opposed to against a surface; and 6.5- but not 5.5-month-olds were more likely to reach for a toy with 100% as opposed to 15% of its bottom on a surface. Infants at each age thus used their support knowledge to determine whether the toys were likely to be retrievable or to be attached to adjacent surfaces and hence irretrievable. These and control findings extend recent evidence that developmental patterns observed in VOE tasks also hold in action tasks, and as such provide further support for the view that VOE and action tasks tap the same physical knowledge.     

内隐社会认知的研究方法综述

内隐社会认知(implicit social cognition)是指在社会认知过程中虽然个体不能回忆某一过去经验(如用自我报告法或内省法),但这一经验潜在地对个体的行为和判断产生影响。内隐社会认知研究采用的是内隐记忆的间接测量技术和方法,使原来行为主义、精神分析学派等无法实证研究的内部心理过程得到了直接的实验室观察。将人的认知过程的两个方面结合起来考察,具有更为全面的理论基础。随着内隐记忆研究方法的不断进步与创新,内隐社会认知已成为社会认知领域的一个研究热点。     

Do fish count? Spontaneous discrimination of quantity in female mosquitofish

The spontaneous tendency to join the largest social group was used to investigate quantity discrimination in fish. Fish discriminated between shoals that differed by one element when the paired numbers were 1vs2, 2vs3 and 3vs4, but not when 4vs5 or larger. Using large numerosities (>4), the ability to discriminate between two numbers improved as the numerical distance between them increased and a significant discrimination was found only with ratios of 1:2 or smaller (4vs8, 8vs16 and 4vs10). Experiments to control for non-numerical variables evidenced the role played by the total area of stimuli with both large and small numerosities; the total quantity of movement of the fish within a shoal appeared also important but only when large numerosities were involved. Even though the pattern of discrimination exhibited by female mosquitofish is not fully consistent with any of the existing models of quantity representation, our results seem to suggest two distinct mechanisms in fish, one used to compare small numbers of objects and one used when larger numerosities are involved.     

Horse sense: social status of horses (<Emphasis Type="Italic">Equus caballus</Emphasis>) affects their likelihood of copying other horses’ behavior

Animals that live in stable social groups need to gather information on their own relative position in the group's social hierarchy, by either directly threatening or by challenging others, or indirectly and in a less perilous manner , by observing interactions among others. Indirect inference of dominance relationships has previously been reported from primates, rats, birds, and fish. Here, we show that domestic horses, Equus caballus, are similarly capable of social cognition. Taking advantage of a specific "following behavior" that horses show towards humans in a riding arena, we investigated whether bystander horses adjust their response to an experimenter according to the observed interaction and their own dominance relationship with the horse whose reaction to the experimenter they had observed before. Horses copied the "following behavior" towards an experimenter after watching a dominant horse following but did not follow after observing a subordinate horse or a horse from another social group doing so. The "following behavior," which horses show towards an experimenter, therefore appears to be affected by the demonstrator's behavior and social status relative to the observer.     

Children's,adolescents', and adults' reference to goals to explain interpersonal actions

This study investigated children's, adolescents', and adults' references to an actor's goals when explaining interpersonal actions. Participants were presented with eight brief stories containing a variety of social events and were asked to explain why the actor in each story performed the central action. Children, adolescents, and adults mentioned goals for most of the stories. Adults and adolescents mentioned psychological goals much more often than did children. Older children, adolescents, and adults mentioned complex psychological goals more often than did younger children. Younger children often mentioned instrumental or social goals. When making goal attributions, children, adolescents, and adults considered both the nature of the action and the social context in which it occurred. Participants mentioned psychological goals more often when explaining an antisocial action and social goals when explaining a prosocial action. Participants were also more likely to mention psychological goals when interpersonal events immediately preceding the central action were described. Thus, goals were offered as explanations for interpersonal actions by all age groups, but the type of goals mentioned varied by the age of the participant, the social context, and the valence of the action.
