发展级联:解释个体纵向发展的新视角

发展级联(developmental cascades)近年来已成为发展心理学追踪研究中一种重要的理论视角。其基本观点是:人的发展过程是一个诸多发展特征不断产生级联效应的过程,某个时间点上个体特征的发展状况会对该特征的后续发展产生影响,并影响其他领域的发展,进而影响到个体的整个发展进程。在发展级联的理论观点基础上形成的相关方法学模型,为探究发展系统中多个因素之间的纵向关联提供了方法学依据与指导。本文介绍了发展级联的相关概念、理论基础、主要观点以及相关的方法学问题,并对其在实证研究中的应用进行了展望。     

学前儿童抑制控制的发展趋势及其对言语理解和数学认知的预测作用

以长春市某幼儿园的122名3~6岁幼儿为被试,采用2(测试任务:无嵌套规则白天黑夜任务,有嵌套规则的白天黑夜任务)×2(测试时间:间隔9个月的第一次测试和第二次测试)×4(年龄分组:3.00~3.75岁组,3.76~4.50岁组,4.51~5.25岁组,5.26~6.00岁组)的三因素混合设计,来分析不同复杂程度的抑制控制在学前阶段的发展趋势,并在控制幼儿年龄和工作记忆水平后,分析不同复杂程度抑制控制对言语理解和数学认知的独立预测作用。结果发现:(1)对3~6岁儿童来说,有嵌套规则的白天黑夜任务的难度水平要显著高于无嵌套规则的白天黑夜任务;(2)较简单的抑制控制(无嵌套规则的白天黑夜任务)在学前阶段的发展速度先快后慢,但较复杂的抑制控制(有嵌套规则的白天黑夜任务)在3~6岁期间持续快速发展;(3)独立于年龄和工作记忆,较复杂的抑制控制能够显著预测幼儿的数学认知和言语理解,但较简单的抑制控制对言语理解和数学认知的预测作用不显著。根据上述结果,在描述学前儿童抑制控制发展趋势时要注意任务难度的设定,而且难度适当的抑制控制任务成绩更能预测幼儿的言语理解和数学认知。     

童年中晚期攻击的发展轨迹和性别差异：基于母亲报告的分析

采用母亲报告的方法, 对1618名儿童的攻击进行了4年(9岁~12岁)的追踪研究, 分析了童年中晚期攻击的一般发展轨迹、亚组发展轨迹以及性别差异。结果发现：(1)总体上, 童年中晚期儿童的攻击水平随年龄而下降。(2)基于亚组的准参数模型分析表明, 童年中晚期母亲报告的儿童攻击呈现三条不同的发展轨迹, 即无攻击轨迹、低攻击—下降轨迹以及持续高攻击轨迹, 各轨迹组人数比例分别约为68.7%、26.8%、4.5%。持续高攻击轨迹组以及低攻击—下降轨迹组的儿童在童年晚期均面临一定程度的人际适应困难。(3)多项Logit模型以及卡方检验表明, 男生更倾向于归属于攻击轨迹组(高或者低攻击轨迹组), 而女生更倾向于归属于无攻击轨迹组; 但这并不说明高攻击轨迹组中没有女生, 约2%的女生属于高攻击轨迹组。     

网络游戏动机的种类、影响及其作用机制

从动机的角度理解网络游戏日益受到研究者的关注。网络游戏动机的研究主要包括：(1)网络游戏动机的种类。在诸多游戏动机中, 乐趣是研究者最为关注的, 其次包括沉醉、社交、逃避、好奇和竞争等。(2)网络游戏动机的影响因素, 包括人格和网络游戏中的社会和个人互动等。(3)动机对网络游戏意向和行为的影响, 这些动机包括乐趣、社交和成就等。(4)网络游戏动机的影响机制, 包括网络游戏动机的中介作用、网络游戏动机与网络游戏行为意向之间的中介变量和调节变量。未来的研究应当关注网络游戏动机种类的分化与整合, 重视从发展心理学、动机的形成和发展过程以及情绪的角度来探讨网络游戏的动机。     

民族认同在民族间态度中的积极作用

社会认同理论提出后,民族认同与民族间态度的关系受到社会心理学家的关注。社会认同理论认为群体认同是群体间态度的基础,过分的民族认同容易产生消极的民族间态度。而发展取向研究认为民族认同与积极的民族间态度的具有正向关系,研究者通过一系列的研究发现,发展成熟的民族认同与积极的民族间态度具有正相关的关系。     

类推理的发展序列与年龄特点

类推理主要涉及类别层级包含关系的理解和判断。使用修订的类包含、替代包含和二元律任务,以162名二至五年级儿童为被试,利用Raseh模型分析方法,旨在揭示儿童逻辑包含能力的发展序列。此外,探讨了儿童类推理发展的年龄特点。结果表明：1）类推理发展中儿童最先掌握类包含推理,其次是替代包含,最后是二元律推理;2）三、四、五年级儿童已能解决多数类包含任务,其成绩显著优于二年级儿童。四、五年级儿童能解决多数替代包含任务,其成绩均显著优于二年级儿童;3）二元律任务对二至五年级儿童来讲均比较困难。     

RESPONSIBILITY AND DISABILITY

Abstract: This essay explores the boundaries of the moral community—the collection of agents eligible for moral responsibility—by focusing on those just inside it and those just outside it. In particular, it contrasts mild mental retardation with psychopathy, specifically among adults. For those who work with and know them, adults with mild mental retardation are thought to be obvious members of the moral community (albeit not full-fledged members). For those who work with and theorize about adult psychopaths, by contrast, they are not members of the moral community (albeit not in such a full-fledged fashion as the insane). Both psychopaths and adults with MMR have a disability, and the essay is interested in how disability sometimes exempts one from the moral community and sometimes doesn't. It will be through two associated puzzles that we will eventually come to see the complicated tripartite relation between disability, responsibility, and moral community.     

Positive attributional style,life events and their effect on children's mood: Prospective study

The present study extended previous research into the role of cognitive style in predicting depressive symptoms in children by examining positive attributional style for positive events in a prospective manner, with a focus on the influence of prior life experience. A non‐clinical sample of 102 children (aged 10–12 years) was recruited. Participants completed self‐report measures of depression, attributional style, stressful life events, and positive life events on two occasions (approximately 6 months apart). Positive attributional style for positive events moderated the relationship between negative life events and follow‐up depressive symptoms. Number of positive events did not significantly moderate the negative life events–depression symptoms relationship although there was a trend in the expected direction. Positive attributional style for positive events appeared to act as both a mediator and moderator in the positive events–depression symptoms relationship. Theoretical and clinical implications of these findings are discussed.     

A longitudinal examination of the transition to symbolic communication in the second year of life

Between 10 and 24 months of age, children progress from communicating through conventional signals to communicating through symbols in a variety of situations. The present study investigates this transition analysing mother–child communication frames and the child's communicative acts, and tracing the developmental changes in both frames and communicative acts. Four children (2 girls, 2 boys) and their mothers were observed longitudinally and extensively, from 10 to 24 months of age, using a multiple case‐study method. Through the detailed investigation of these single cases, clear developmental rajectories were found, showing that conventional frames and representational gestures ‘bridge’ the transition from attentional to symbolic communication. There were significant differences between dyads and children in the developmental trajectories for several frames and communicative acts. The results not only confirm previous findings on the development of verbal and gestural communication, but provide new insights into the transition to symbolic communication in the second year of life, first because of the use of frame analysis and second because of a focus on individual trajectories in development.

The Cornell Institute for Research on Children: A vision of integrated developmental science

The Cornell Institute for Research on Children (CIRC) is an intellectual infrastructure funded by the National Science Foundation under the aegis of the Children's Research Initiative, which was spearheaded by Rodney R. Cocking. Cocking's vision of integrated developmental science is an integral part of CIRC's philosophy. CIRC aims to integrate knowledge and paradigms from a variety of fields (e.g., developmental psychology, economics, neuroscience, and pediatrics), which take different perspectives on similar issues (e.g., the effects of toxins on cognitive development), making it explicitly interdisciplinary. The object of CIRC studies is to apply research findings to social policy. To accomplish this, CIRC provides resources to enable teams of scholars from diverse fields to collaborate on policy-relevant questions. CIRC's approach begins by asking policy-makers to define questions for researchers to address, then shepherds the process by which scholars from various relevant disciplines are commissioned to work as a team to answer such questions. To demonstrate the strengths of this approach we describe the six components that comprise CIRC and provide an actual example of a project that CIRC has commissioned as well as a hypothetical example of a project that CIRC could undertake. This article is a progress report, written in an effort to disseminate information about CIRC's agenda.
