Coactive processing of sensory signals for in-group but not out-group stimuli

ABSTRACT

There is ample evidence showing that decision times are shorter when detecting two targets for which the same response is required, compared to when only one of the targets is present—resulting in a redundancy gain. Though effects of perceptual manipulations on redundancy gains are established, effects of social associations are still unclear. Here, we examined for the first time whether associating arbitrary stimuli with in-group as opposed to out-group targets modulates redundancy gains. Participants made associations between a shape, a colour and either in- or out-group labels. They then had to discriminate whether in- or out-group stimuli appeared (single or redundant features). Responses to in-group but not to out-group stimuli violated predictions of models in which the associated features are processed independently, and were consistent with in-group stimuli being processed with super-capacity. Our results, replicated across two experiments, providing the first evidence that there is enhanced perceptual integration for information associated with an in-group.     

熟悉性对外群体同质性效应的影响

两个实验考查了年龄和性别群体中是否存在外群体同质性效应以及熟悉性对该种效应的影响。结果表明：1．年龄群体中存在明显的外群体同质性效应,这与青年群体和老年群体彼此不够熟悉有关;2．性别群体中不存在外群体同质性效应,这与青年男女群体彼此较为熟悉有关。     

‘Shh … quiet! Here they come.’ Black employees as targets of office gossip

This study explored black employees’ experiences of racial profiling by their white peers through the medium of gossip at a historically white, South African university. Participants consisted of 24 black employees (males = 50%, females = 50%; support staff = 50%, academic staff = 50%). The employees completed a semi-structured interview that elicited their perceptions of the settings in which gossip about black employees occurred, the perceived intentions of such gossip, and their responses to it. The data obtained was thematically analysed. Findings suggested that the gossip targeted black employees who were absent from meetings, and that such gossip undermined the work performance and morale of these employees.     

群体偏好与年级对小学生利他惩罚行为的影响

采用独裁者博弈（DG）探讨了群体偏好对不同年级小学生利他惩罚行为的影响。研究1对450名小学生利他惩罚行为的年级发展特点进行了测查。研究2以168名小学生为被试,考察了在独裁者博弈中与独裁者的关系、性别与年级对小学生（第三方）利他惩罚行为的影响。研究3以180名小学生为被试,考察了在独裁者博弈中与接受者的关系、性别与年级对小学生（第三方）利他惩罚行为的影响。结果发现：（1）利他惩罚行为在1至3年级之间有显著增长,3至5年级之间不仅没有增加反而有所下降。（2）3年级小学生开始表现出明显的群体偏好。（3）利他惩罚行为的性别差异不明显,与女生比男生更利他的预期相左。结论：小学生至少在6岁就已经出现了利他惩罚行为且逐渐表现出群体偏好;小学生道德行为发展中可能存在“3年级现象”;女生可能更愿意通过非惩罚的方式达成公平。     

Children and adolescents coordinate group and moral concerns within different goal contexts when allocating resources

Coordinating complex social and moral concerns when allocating resources is a key issue in late childhood and early adolescence. This study explored resource allocation in three goal contexts that required children to focus to differing degrees on moral and group concerns. Children (9–11-years, M^age = 9.84, n = 190) and adolescents (14–16-years, M^age = 14.92, n = 154) were informed their school peer group held an in-group norm (competition, cooperation). Participants allocated resources between their in-group and an outgroup within one of three goal contexts (prosocial, learning-focused, and group-focused). Participants allocated in favour of their in-group to achieve a prosocial goal but attenuated this when the goal was focused on learning and cooperation. Adolescents, more than children, reasoned about the goals of resource allocation to justify their decisions. From 9 years old, children begin to coordinate peer group norms and goal information when deciding how to allocate resources within intergroup contexts.     

刻板印象的激活效应:行为和ERPs证据

以刻板印象表征中的核心内容——刻板特质词作为研究材料,采用分类-确认范式对刻板印象激活效应的时间进程及其认知机制进行了探讨。以性别范畴词"男"/"女"作为启动刺激,以性别刻板特质词作为靶子,特质词与范畴词构成一致和冲突两种情境,记录了34名被试(男女各半)对特质词与范畴词进行一致性判断时的行为反应和ERPs。结果发现:(1)刻板印象冲突情境下,因刻板印象激活效应的作用,被试的反应时要比刻板印象一致情境下更长;不同性别的被试均表现出性别内群体范畴词激活优势效应,即内群体范畴词启动条件下反应时更短。(2)刻板印象激活效应对早期ERP成分(P1、N170、N100、P2)没有影响,在刻板印象冲突情境下诱发了额-中区更显著的N400,该成分标志着刻板印象的激活效应;不同性别的被试均在内群体范畴词启动下诱发了波幅更大的P600。(3)刻板印象的激活效应以及内群体范畴词激活优势效应均发生在知觉后阶段。     

儿童公平行为的发展——来自博弈实验的证据

公平正义一直是人类不懈追求的目标,是心理学、经济学等多个学科共同关注的一个重要课题。发展心理学常采用故事法对儿童的公平认知进行研究,博弈范式的引入则为研究儿童的公平行为提供了新的方法和角度。该文主要介绍了独裁者博弈和最后通牒博弈中儿童公平行为的发展趋势,并对已有的矛盾性结论进行了原因分析,探讨了公平行为的内团体偏差效应、公平的本质是意图公平还是结果公平、以及心理理论与公平行为的关系等问题。最后,该文指出今后对儿童公平行为的研究应充分考虑社会情境与社会认知能力的影响。     

内群体偏爱与儿童基于贡献的分配公平性:心理理论的调节作用

本研究考察了贡献和内群体偏爱两种分配动机对儿童分配公平性的影响,并探讨了心理理论在其中的作用。通过比较63名6~8岁儿童在不同群体条件下对贡献不同的接受者的分配结果和分配策略的差异,结果发现：（1）在所有群体条件下,儿童都会分配给贡献多的接受者更多的资源,但当外群体成员贡献多且内群体成员贡献少时,儿童也会分配给贡献多的接受者相比于其他群体条件更少的资源,并更多的采用群体关系策略对这一行为作出解释;（2）心理理论能力越高的儿童分配给贡献多的接受者的资源数量受群体关系的影响越小,且使用贡献策略的频率越高,使用群体关系策略的频率越低。这些结果表明6~8岁儿童在资源分配过程中会优先考虑公平动机,且心理理论能力强的儿童更少表现出内群体偏爱。     

Too great to act in solidarity: The negative relationship between collective narcissism and solidarity-based collective action

Three studies examined the association between narcissistic identification with one’s advantaged in-group and engagement in solidarity-based collective action. Drawing on theory and past research, a negative effect of collective narcissism on solidarity-based collective action was expected. A two-wave longitudinal study (N = 162) found that Polish participants’ narcissistic, but not secure, national identification decreased their willingness to engage in collective action in solidarity with refugees over time. A field study (N = 258) performed during a mass protest against a proposed abortion ban showed that men’s gender-based collective narcissism was a negative predictor of solidarity-based engagement (operationalized as protest behavior and collective action intentions) and this effect was mediated by lowered empathy for women. Finally, a web-based survey (N = 1,992) revealed that heterosexual/cisgender individuals’ collective narcissism was negatively associated with collective action intentions in support of LGBT rights and that this effect was sequentially mediated by increased intergroup anxiety and decreased empathy for LGBT people. Theoretical implications of the present findings, research limitations, and future directions are discussed.     

Culture and group-based emotions: could group-based emotions be dialectical?

Group-based emotions are experienced when individuals are engaged in emotion-provoking events that implicate the in-group. This research examines the complexity of group-based emotions, specifically a concurrence of positive and negative emotions, focusing on the role of dialecticism, or a set of folk beliefs prevalent in Asian cultures that views nature and objects as constantly changing, inherently contradictory, and fundamentally interconnected. Study 1 found that dialecticism is positively associated with the complexity of Chinese participants’ group-based emotions after reading a scenario depicting a positive intergroup experience. Study 2 found that Chinese participants experienced more complex group-based emotions compared with Dutch participants in an intergroup situation and that this cultural difference was mediated by dialecticism. Study 3 manipulated dialecticism and confirmed its causal effect on complex group-based emotions. These studies also suggested the role of a balanced appraisal of an intergroup situation as a mediating factor.
