Friendship Quality and School Achievement: A Longitudinal Analysis During Primary School

This study examined the longitudinal relationship between friendship quality (positive and negative) and school achievement among 228 school-age children (51% girls, M = 8.09, SD = 0.41). A three-wave cross-lagged analysis was used to determine the direction of influence between these domains across school years. Findings revealed that: (a) school achievement in second grade decreased negative friendship quality in third grade; (b) school achievement in second grade predicted positive friendship quality in third grade; (c) positive friendship quality in third grade predicted school achievement in fourth grade. The protective role of school achievement against peer relationship impairment and the reciprocal relationship between positive friendship quality and school achievement were underlined. Implications for educational practices for Italian primary schools are discussed.     

Positional Sequences in Two-Choice Discrimination Problems with Non-Positional Cues

Individuals seem to differ in their ability to maintain consistent performance. This is obviously an important attribute of behavior that has been largely neglected by researchers. There is, however, some evidence to suggest that, in certain types of situations, the behaviors of the mental retardate are characterized by a relatively high degree of variability. Two studies are reported here that deal with some of the developmental implications of intraindividual variability. In one study, involving retardates, reliability and generality of response consistency were examined in reaction time, time estimation, and digit span tasks. It was shown that individual differences in consistency are reliable and that these generalize across tasks. A second experiment was concerned with the developmental aspects of variability. First-, third-, and fifth-grade pupils and college students were given many trials on a reaction-time task. A variety of measures, reflecting typical performance, limit of performance, and variability, were computed for each subject. The ability to react quickly shows a developmental trend not only with respect to overall performance, but also in the efficiency with whichthe individual maintains his optimal level of responding.     

Virtue or Art?: Political Friendship Reconsidered

In Talking to Strangers (2004), Danielle Allen argues that democratic citizens will need to acquire new habits for contending with distrust in order to prolong the democratic experiment. Though Allen's solution recalls her reading of the Republic, it is to Aristotle, not Plato, that she turns for help theorizing those habits. Drawing upon the Nicomachean Ethics, she proposes arts or techniques that might substitute for and outpace justice by enabling democratic strangers to treat one another like friends. While I endorse Allen's analysis of the problems posed by rising levels of distrust, I propose a different solution. First, I argue that the habits Allen describes would have to be virtues and not merely techniques in order to effect real political change. Then, second, I identify those habits as “piety” and “gratitude”—virtues which, I contend, are not so much substitutes for as supplements to justice. My argument thus elaborates Thomas Aquinas's account of justice and its “potential parts” in the Summa Theologiae.     

论达尔文的最佳解释推理

科学研究需要正确的思维方法的指导,而最佳解释推理就是一种重要的思维方法。达尔文运用最佳解释推理论证通过自然选择而进化的理论最为成功,在《物种起源》中,达尔文以解释力、解释的一致性为基础,引用大量事实,充分比较了自然选择理论与上帝的独立创造说或神创论,符合最佳解释推理模型的评价标准。     

亲子关系、朋友关系影响问题行为的3种模型

家庭和同伴是影响个体发展的最重要的微系统, 是儿童青少年问题行为的重要影响因素,以往对上述问题的实证研究非常广泛, 但很零散。对前人研究的分析发现亲子关系、朋友关系影响问题行为有3种模型：独立模型、交互影响模型和间接效应模型, 然而这些模型及其有关研究仍存在诸多问题与不足, 如亲密关系测量指标不统一, 内外化问题行为研究不均衡, 评价主体单一化, 文化差异, 缺乏充分的追踪研究和实验设计等, 未来研究应对上述方面加以关注。     

父母支持、友谊支持对早中期青少年孤独感和抑郁的影响

以391名初一(青少年早期)和高一(青少年中期)学生为被试, 探讨了父母支持、友谊支持对孤独感和抑郁的影响模式。结果表明：(1)友谊支持是预测孤独感的更好指标, 父母支持是预测抑郁的更好指标; (2)父母支持和友谊支持仅对早期青少年孤独感和抑郁的影响存在显著交互作用, 但作用模式不同：父母支持可增强高友谊支持对降低青少年孤独感的作用(增强模式)而友谊支持可补偿低父母支持对降低青少年孤独感的作用(补偿模式); 两种支持系统可相互增强对方对降低青少年抑郁水平的效应(相互增强模式)。(3)与青少年早期不同, 青少年中期父母支持和友谊支持两个系统以“独立模式”而非“交互模式”影响青少年的情绪适应。结果提示, 家庭和同伴系统对青少年情绪适应的影响可能遵循多种模式, 但分别适用于不同适应问题和发展阶段。     

父母支持、友谊质量对孤独感和抑郁的影响：检验一个间接效应模型

以560名5、7、10年级学生为被试, 检验父母支持、友谊质量与孤独感、抑郁的关系是否符合间接效应模型及其模型适用性问题。结构方程建模及群组分析结果发现：(1)总体上, 间接效应模型成立, 父母支持既直接影响孤独感和抑郁, 也通过影响友谊质量进而影响孤独感和抑郁状况; (2)从具体适应问题看, 间接效应模型对于孤独感和抑郁均显著, 但更适用于对孤独感的预测; (3)从发展阶段看, 间接效应模型仅适用于童年晚期和青少年早期, 且更适用于童年晚期; (4)从性别角度看, 间接效应模型对两性均显著, 但更适用于男生。结果提示, 父母支持、友谊质量对孤独感和抑郁的影响均符合间接效应模型, 但该模型的适用性可能因具体适应问题、发展阶段和性别而有差异。     

儿童的两种亲密人际关系:亲子依恋与友谊

以城市三所普通小学四、五、六年级的505名学生为被试,用问卷调查、团体施测的方式,探讨儿童亲子依恋与其友谊的关系,结果发现：在儿童友谊质量方面,父、母均有影响,在友谊的数量,如好朋友提名分方面母亲的作用也是显见的;亲子依恋特质的两成分(信赖、亲近)对儿童友谊质量的积极特征和冲突水平有相对不同预测力。     

Friendship and loneliness among bullies and victims: Data from seven countries

Research suggests that the relationship between school bullying and its various risk factors should be clearer among girls than boys, and should become stronger with age, as roles within the peer group stabilise. This paper tests this theory by comparing sex, school type, and bully/victim status differences in friendships and playground social interactions, using data from nine surveys in seven countries: China, England, Ireland, Italy, Japan, Portugal, and Spain. A total of approximately 48,000 children completed various translations of the Olweus Bullying Questionnaire. Small but generally consistent main effects were found for sex and school type (boys and primary pupils enjoyed playtimes more and had more friends, but were also more likely to spend playtimes alone). Larger effects were consistently found for bully/victim status (victims were significantly worse off on all the measures in all the samples where a difference was found, while bullies and neutrals did not differ consistently), but the interactions between these factors varied widely between samples and there were few consistent patterns. It is concluded that bullying is a universal phenomenon with many negative correlates for victims and few (if any) for bullies, but that there are cultural variations in the way that bullying is related to sex, age, and social support.
