Trajectories of Social Withdrawal from Middle Childhood to Early Adolescence

Heterogeneity and individual differences in the developmental course of social withdrawal were examined longitudinally in a community sample (N = 392). General Growth Mixture Modeling (GGMM) was used to identify distinct pathways of social withdrawal, differentiate valid subgroup trajectories, and examine factors that predicted change in trajectories within subgroups. Assessments of individual (social withdrawal), interactive (prosocial behavior), relationship (friendship involvement, stability and quality, best friend’s withdrawal and exclusion/victimization) and group- (exclusion/victimization) level characteristics were used to define growth trajectories from the final year of elementary school, across the transition to middle school, and then to the final year of middle school (fifth-to-eighth grades). Three distinct trajectory classes were identified: low stable, increasing, and decreasing. Peer exclusion, prosocial behavior, and mutual friendship involvement differentiated class membership. Friendlessness, friendship instability, and exclusion were significant predictors of social withdrawal for the increasing class, whereas lower levels of peer exclusion predicted a decrease in social withdrawal for the decreasing class.     

Childhood peer relationships: social acceptance, friendships, and peer networks

This review addresses several areas of contemporary research in children's peer relationships during the elementary and middle school years, with primary foci on children's peer acceptance, the ability to make and maintain friendships, and their participation in larger peer networks. Particular attention is given to research examining the major developments and individual differences in each of these components of children's peer relations, how these different aspects of peer functioning relate to one another, and how they contribute to development more generally, including school adjustment and achievement. Finally, it is argued that children's psychosocial development may be best informed by an integration of these somewhat independent research traditions.     

In Friendship: A Place for the Exploration of Being Human

Abstract

The ancient Greek philosophical discourse harbors an anthropology radically discontinuous with the framework of modernity. Rather than emphasizing the tension between the individual and community, and far from understanding the political on the ground of instinctual sacrifice (a constant from Hobbes, to Nietzsche, to Freud), Greek thought illuminates the interdependence of ethics and politics, and situates the human being in a cosmos in which the human is neither central nor prominent. In particular the reflection of philia, most notably in Plato and Aristotle, calls for the exploration of human potentiality with outstanding vigor and visionary audacity.     

青少年特质情感、朋友冲突解决策略对友谊质量的影响

为考察特质情感对青少年友谊质量的影响机制,以638名小学四年级至初中三年级青少年为被试,用问卷法考察青少年朋友冲突解决策略的类型和特点,采用结构方程模型进行分析。结果表明:(1)青少年朋友冲突解决策略类型包括反省和解、说服建议、消极情绪、忽视回避和攻击伤害五种,女生的反省和解策略得分高于男生,男生的攻击伤害策略得分高于女生。(2)积极情感以积极解决策略为中介预测积极友谊质量,积极情感还对积极友谊质量具有直接预测作用。(3)消极情感通过积极和消极的解决策略为中介,分别预测积极友谊质量和消极友谊质量;消极情感对于友谊质量没有直接预测作用。说明积极情感与消极情感是通过不同的路径、相对独立地影响友谊质量。     

When surface and deep-level diversity collide: The effects on dissenting group members

Diversity researchers have distinguished between surface-level (e.g., social categories) and deep-level (e.g., attitudes, opinions, information, and values) diversity, but have not fully explored the complexities of their simultaneous existence in groups. We examined how the relationship between surface-level and deep-level diversity impacts the emotional and behavioral reactions of dissenting group members and the effectiveness of decision-making groups. We conducted two studies focusing on dissenting social majority members (individuals who hold dissenting deep-level task perspectives yet belong to the surface-level majority) in three-person groups. The results show that surface-level diverse groups (with two similar and one dissimilar individuals) were perceived as more positive and accepting, fostered more persistent and confident voicing of dissenting perspectives, and displayed greater task engagement than surface-level homogeneous groups (containing all similar individuals). Surface-level diversity (both task-relevant and irrelevant) may be beneficial for groups even when the group member who is different on the surface does not have a different deep-level task perspective to share. We discuss implications for understanding how surface-level diversity affects organizational work groups.     

Knowledge, expectations, and inductive reasoning within conceptual hierarchies

Previous research (e.g. Cognition 64 (1997) 73) suggests that the privileged level for inductive inference in a folk biological conceptual hierarchy does not correspond to the “basic” level (i.e. the level at which concepts are both informative and distinct). To further explore inductive inference within conceptual hierarchies, we examine relations between knowledge of concepts at different hierarchical levels, expectations about conceptual coherence, and inductive inference. In Experiments 1 and 2, 5- and 8-year-olds and adults listed features of living kind (Experiments 1 and 2) and artifact (Experiment 2) concepts at different hierarchical levels (e.g. plant, tree, oak, desert oak), and also rated the strength of generalizations to the same concepts. For living kinds, the level that showed a relative advantage on these two tasks differed; the greatest increase in features listed tended to occur at the life-form level (e.g. tree), whereas the greatest increase in inductive strength tended to occur at the folk-generic level (e.g. oak). Knowledge and induction also showed different developmental trajectories. For artifact concepts, the levels at which the greatest gains in knowledge and induction occurred were more varied, and corresponded more closely across tasks. In Experiment 3, adults reported beliefs about within-category similarity for concepts at different levels of animal, plant and artifact hierarchies, and rated inductive strength as before. For living kind concepts, expectations about category coherence predicted patterns of inductions; knowledge did not. For artifact concepts, both knowledge and expectations predicted patterns of induction. Results suggest that beliefs about conceptual coherence play an important role in guiding inductive inference, that this role may be largely independent of specific knowledge of concepts, and that such beliefs are especially important in reasoning about living kinds.     

Friendship and adjustment among adolescents

This study investigated the relation of friendship and emotional adjustment in adolescents. Both quantitative (popularity, mutual friendships, and number of friends) and qualitative dimensions (perceived positive friendship quality and conflict) of friendship were used. Participants were 618, mostly European American, 8th-, 10th-, and 12th-graders. Structural equation modeling showed that positive friendship quality was the only friendship variable that predicted adjustment. An examination of gender effects indicated that this relation held only for boys. The quantitative aspects of friendship had a small, indirect effect on adjustment through their effects on positive quality. Conflict had a negative effect on positive quality and this effect was stronger for girls than for boys. The role of adolescents' perception in adjustment was highlighted and suggestions for future research were made.     

Adolescents' interactions with a best friend: associations with attachment style

This study tested whether adolescents' attachment style is related to friendship interactions and perceptions of friendship quality. Attachment pairings were contrasted to examine whether dyad members' security of attachment or their models of others was more related to friendship. A total of 44 pairs of same-sex adolescent friends were videotaped as they engaged in an intimate conversation. Participants also completed self-report measures of attachment style and friendship quality. Compared with dyads with at least one insecure partner, dyads with two secure members interacted in ways that promoted a sense of connection with each other. In addition, they did not use as many clarification statements, suggesting a smooth conversational style between the friends. When friend pairs were examined based on positive or negative models of others (i.e., dismissing and fearful vs secure and preoccupied), there were no differences. The findings suggest that security of attachment, rather than type of insecurity, is most related to intimacy in friendship.
