快速节俭启发式——相关争议与简短评论

在有限理性和生态理性假设基础上,Gigerenzer教授和在他指导下的“ABC研究组”发现并提出了再认启发式、采纳最佳启发式、优先启发式、道德启发式等一系列“快速节俭启发式”。大量研究表明这些简单决策规则是节省信息的合理而高效的认知策略,但也有一些研究者对它们表示怀疑。在本文中,作者对近期关于快速节俭启发式的一般争议及围绕采纳最佳启发式、优先启发式、道德启发式展开的具体争议进行了回顾与总结,给出了简短的评论。快速节俭启发式是一个富有前景、却又布满荆棘的研究领域。要想实现宏伟的研究目标,ABC研究组尚需做出更多、更大的努力。     

小学儿童互选友谊的发展趋势及攻击行为的影响：3年追踪研究

对小学3、4年级的285名儿童进行了3年追踪调查,分析了儿童分别与男、女生互选友谊数的变化趋势及其在个体间的差异,探讨了外部攻击和关系攻击分别对两类互选友谊数的影响。结果表明：（1）儿童的男、女生互选友谊数在3年时间内都有显著的增加趋势,并表现出显著的性别差异,儿童与同性互选友谊数显著多于他们与异性的互选友谊数,男生与女生互选友谊数的增加速度比女生与女生互选友谊数增加速度慢,儿童与男生的互选友谊数越多,他/她与女生的互选友谊数就越少,表明了性别隔离现象的存在。（2）在控制了关系攻击的影响后,儿童的外部攻击对他们在各时间点测得的与女生的互选友谊数有显著的消极影响,而对他们与男生的互选友谊数影响不显著;在控制了外部攻击的影响后,儿童的关系攻击对他们在各时间点测得的与女生的互选友谊数有显著的积极影响,而对他们与男生的互选友谊数影响不显著。这说明外部攻击和关系攻击对儿童互选友谊数的影响存在性别差异     

社交网站中的自我呈现对青少年友谊质量的影响:积极反馈的中介作用

随着网络的日益普及,社交网站已成为人们活动的新领域和人际交往的新媒介。为探讨社交网站中不同的自我呈现方式、积极反馈与友谊质量的关系,采用问卷法对来自武汉市两所普通中学的817名10~19岁的学生进行调查,其中,男生423人,女生366人。研究采用偏差矫正的百分位Bootstrap法,使用Hayes(2012)编制的SPSS宏对中介效应进行检验,结果发现:(1)真实自我呈现和积极自我呈现与积极反馈、友谊质量显著正相关;(2)社交网站中的真实自我呈现既能直接预测青少年的友谊质量,也能通过积极反馈的中介作用对友谊质量产生影响,而积极自我呈现对青少年的友谊质量没有直接预测作用,只能通过积极反馈的完全中介作用对友谊质量产生影响。     

多元视角下的异性友谊

异性友谊是一种重要的人际关系。已有研究考察了一般异性友谊的特点、影响和维系, 同时也考察了利友关系的心理特征和身心影响。异性朋友可能会对青少年和大学生的社会适应带来消极影响, 但这一影响可能具有文化差异。进化心理学取向的研究者主要考察了异性友谊的进化功能, 他们认为异性友谊能够帮助个体完成长期择偶目标或短期择偶目标, 同时还能够为个体提供重要的择偶信息。未来研究有必要结合新出现的友谊理论, 考察不同年龄阶段的异性友谊, 同时关注异性友谊中的个体差异变量, 比如人际性行为取向、暗黑三合一性格和择偶智力。     

Do Gender and Age Moderate the Relationship between Friendship Quality and Non-Suicidal Self-Injury in Community Children and Adolescents?

In the present study, we investigated the relationship between friendship quality (dimensions) and non-suicidal self-injury (NSSI) as well as the moderating role of gender and age in this relationship. The sample consisted of 463 children and adolescents (50.10% female, age range: 9–17 years). Friendship quality and NSSI were measured using the Friendship Qualities Scale (FQS; Bukowski, Hoza, & Boivin, 1994) and the Self Harm Inventory (SHI; Sansone, Wiederman, & Sansone, 1998), respectively. Overall, total friendship quality and NSSI were significantly and negatively related. Additionally, the relationship between total friendship quality and NSSI was moderated by gender and age. Specifically, girls with low friendship quality reported more NSSI; whereas for boys an opposite effect was found. As for age, friendship quality and NSSI were positively related in older participants. In younger participants, a relationship between friendship quality and NSSI seemed rather absent. This study highlights the important association between friendship quality and NSSI, as well as gender- and age-related differences in this association, which should be taken into account in the prevention and treatment of NSSI.     

Juvenilized play fighting in subordinate male rats

As pairs of male juvenile sibling rats that are housed together become sexually mature, they develop a dominance-subordinance relationship. These dominance relationships appear to be reflected in the play fighting of the pairmates both as juveniles and as young adults, in that the seemingly subordinate partner initiates more playful attacks at both ages. However, as adults, even though it is the subordinate that initiates more playful attacks, it is the subordinate that is pinned on his back by the partner most often. Dominant pairmates were found to switch to defensive patterns typically found in adult males. In contrast, the subordinates, when contacted on the nape, were more likely to retain the juvenile pattern of turning over to supine. Therefore, the subordinate pairmate of an adult pair of male siblings both initiates more playful attacks and defends itself in a more juvenile manner than its dominant partner, and this leads to it being pinned more frequently. This pattern of behavior by subordinate rats is suggested to function as a friendship maintenance mechanism permitting co-existence in multimale colonies.     

童年中晚期友谊质量与抑郁的关系:一项纵向研究

以友谊质量问卷和儿童抑郁量表为研究工具,对小学3到4年级847名儿童进行了18个月的追踪研究,采用交叉滞后的研究设计,考察了童年中晚期友谊质量与抑郁的关系。结果表明：（1）同一时间点的友谊质量和抑郁之间呈显著的负相关;（2）早期的友谊质量可以显著预测随后的抑郁,早期的抑郁也可以显著预测随后的友谊质量,且相对于友谊质量对抑郁的积极作用,抑郁对儿童友谊质量的瓦解作用更为突出;（3）童年中晚期友谊质量与抑郁的双向作用关系具有跨性别稳定性。     

Improving Intergroup Relations with Extended Contact among Young Children: Mediation by Intergroup Empathy and Moderation by Direct Intergroup Contact

A correlational study investigated extended contact as a strategy to improve outgroup attitudes and stereotyping and to prepare children for future contact. Additional aims were to investigate when and why the effects of extended contact occur. In particular, intergroup empathy was tested as a mediator and direct contact (i.e. cross‐group friendship) as a moderator of extended contact. Participants were Italian and immigrant elementary school children. Results showed that extended contact was associated with improved intergroup empathy, which, in turn, was associated with more positive outgroup attitudes, stereotypes and behavioural intentions. These effects were significant only among participants with a low or moderate level of direct contact. The theoretical and practical implications of findings are discussed.

Daily School Context of Adolescents' Single Best Friendship and Adjustment

Research on adolescent best friendships typically focuses on school-based friendships, ignoring important differences between classroom-based and out-of-school friendships. With data from 156 ninth-grade students, many of whom named more than 1 best friend across the 14-day period, the authors examined associations between the daily school context of one's best friendship and adjustment. Benefits of in-grade best friendships were found in academic engagement when a composite was assessed across the 2-week period. Daily findings were more complex and were different between weekends and school days. Out-of-grade best friends were named more frequently on weekends, and on weekend days in which they named an out-of-school best friend participants spent more time with that friend but felt like less of a good student. Implications for our understanding of friendship context and for the measurement of friendship itself are discussed.
