| 1 | 合作行为研究综述:社会认知理论的视角显示文摘合作行为在人们日常生活中不可或缺,与个体自身及其所在群体甚至与国家民族的福祉息息相关。合作行为的影响因素主要来源于个体与环境,包括人格特征、个人期望、奖惩制度以及文化背景等影响因素,主要采用行为实验和问卷测量两种评估方式。文章从社会认知理论的视角对合作行为的测量、影响合作行为产生的个体与环境因素以及合作行为的效果进行了综述分析,并批判性地提出了未来可能的研究方向。 | 陈晓秋 范为桥 | 2020 | 心理学通讯2020，3，3： | 5 |
| 2 | Using multilayer network analysis to explore the temporal dynamics of collective behavior显示文摘Social organisms often show collective behaviors such as group foraging or movement.Collective behaviors can emerge from interactions between group members and may depend on the behavior of key individuals.When social interactions change over time,collective behaviors may change because these behaviors emerge from interactions among individuals.Despite the importance of,and growing interest in,the temporal dynamics of social interactions,it is not clear how to quantify changes in interactions over time or measure their stability.Furthermore,the temporal scale at which we should observe changes in social networks to detect biologically meaningful changes is not always apparent.Here we use multilayer network analysis to quantify temporal dynamics of social networks of the social spider Stegodyphus dumicola and determine how these dynamics relate to individual and group behaviors.We found that social interactions changed over time at a constant rate.Variation in both network structure and the identity of a keystone individual was not related to the mean or variance of the collective prey attack speed.Individuals that maintained a large and stable number of connections,despite changes in network structure,were the boldest individuals in the group.Therefore,social interactions and boldness are linked across time,but group collective behavior is not influenced by the stability of the social network.Our work demonstrates that dynamic social networks can be modeled in a multilayer framework.This approach may reveal biologically important temporal changes to social structure in other systems. | David N.FISHER Noa PINTER-WOLLMAN | 2021 | Current Zoology2021，67，1： | 1 |
