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。     

多变量追踪研究的模型整合与拓展：考察往复式影响与增长趋势

追踪研究当中, 交叉滞后模型可以探究多变量之间往复式影响, 潜增长模型可以探究个体增长趋势。对两类模型进行整合, 例如同时关注往复式影响与个体增长趋势, 同时可以定义测量误差、随机截距等变异成分, 衍生出随机截距交叉滞后模型、特质-状态-误差模型、自回归潜增长模型、结构化残差潜增长模型等。以交叉滞后模型和潜增长模型分别作为基础模型, 从个体间/个体内变异分解的角度对上述各类模型梳理, 整合出此类模型的分析框架, 并拓展建立“因子结构化潜增长模型(factor latent curve model with structured reciprocals)”作为统合框架。通过实证研究(早期儿童的追踪研究-幼儿园版, ECLS-K), 建立21049名儿童的阅读和数学能力的往复式影响与增长趋势。研究发现, 分离了稳定特质的模型拟合最优。研究也对模型建模思路和模型选择提供了建议。

采用问卷法对101名初中生在两年半间数学元认知的发展状况进行5次测试。利用潜类别增长模型等探讨初中生数学元认知的发展轨迹,并考察性别对数学元认知的影响。结果发现：(1)初中生数学元认知及各成分在初二表现出下降趋势。(2)初中生数学元认知的发展表现出三种类型,即高-缓慢下降组(32.67%)、中-显著下降组(54.46%)以及低-缓慢下降组(12.87%)。(3)与女生相比,男生有着更多的数学元认知知识和更高的数学元认知初始水平,且与低-缓慢下降组相比,男生比女生更有可能属于高-缓慢下降组。     

汉语儿童语素意识与词汇知识的双向关系:一项追踪研究

以399名小学一、三、五年级学生为被试,进行为期一年的追踪研究,通过分层回归,系统考察了汉语儿童同音、同形和复合三类语素意识与词汇知识的双向关系。结果发现:(1)儿童语素意识和词汇知识随时间均有显著增长;(2)控制词汇知识的自回归效应后,一年级儿童的同音和复合语素意识对其二年级的词汇知识、三年级儿童的复合语素意识对其四年级的词汇知识、五年级儿童的同形和复合语素意识对其六年级的词汇知识有显著的预测作用;(3)分别控制三类语素意识的自回归效应后,一年级和五年级儿童的词汇知识可以显著预测其二年级和六年级的三类语素意识,三年级儿童的词汇知识对其四年级的同形和复合语素意识有显著预测作用。结果表明汉语儿童语素意识与词汇知识存在双向关系,且不同类型的语素意识与词汇知识的关系随年级的升高呈现规律性的变化。     

Friendlessness and theory of mind: A prospective longitudinal study

Chronic friendlessness in childhood predicts adverse mental health outcomes throughout life, yet its earliest roots are poorly understood. In theory, developing a theory of mind (ToM) should help children gain mutual friends and one preschool study (Peterson & Siegal, 2002. Br J Dev Psychol, 20, 205) suggested a cross‐sectional connection. We therefore used a 2‐year prospective longitudinal design to explore ToM as a predictor of mutual friendship in 114 children from age 5 to 7 years after controlling potential confounds including language ability and group popularity. Confirming friendship's distinctiveness from group sociometric status, numerous group‐rejected children (53%) had a mutual friend whereas 23% of those highest in group status did not. Five‐year‐olds with a mutual friend significantly outperformed their friendless peers on a comprehensive ToM battery (basic and advanced false belief). Longitudinally, chronically friendless 7‐year‐olds (no friends at either testing time) stood out for their exceptionally poor Time 1 ToM understanding even after controlling for group popularity, age, and language skill. Extending previous evidence of ToM's predictive links with later social and cognitive outcomes, these results for mutual friendship suggest possible interventions to help reduce the lifelong mental health costs of chronic friendlessness.     

Association of prenatal attachment and early childhood emotional,behavioral, and developmental characteristics: A longitudinal study

This study examines the associations between prenatal attachment and child development, socioemotional behavioral problems, and competence at early childhood. It also inquires whether maternal depression and anxiety at the prenatal period and at early childhood are associated with child outcomes. The study consisted of 83 mothers and their children. Data regarding the prenatal attachment, depression, and anxiety were collected during Weeks 28 to 40 of gestation. When the children were 21 to 31 months old, the Brief Infant and Toddler Social Emotional Assessment (BITSEA) and the Ankara Developmental Screening Inventory (ADSI) were applied to children along with Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) administered to mothers. Results showed that prenatal attachment scores significantly correlated with BITSEA-Competency subscale scores and ADSI total scores at early childhood, r(83) = 0.246, P = .025, and r(82) = 0.316, P = .004, respectively. Prenatal attachment levels were found to be the predictors of both behavioral and emotional competence and development at early childhood, b = 0.081, t(83) = 2.273, P = .014, and b = 0.281, t(83) = 3.225, P = .002, respectively. In addition, prenatal attachment was shown to be even a stronger predictor of development than was worsening maternal depression at early childhood, b = −0.319, t(83) = 2.140, P = .035. Our results indicate that fostering prenatal attachment may be beneficial for better infant outcomes at early childhood.     

Trajectories and predictors of indirect aggression: results from a nationally representative longitudinal study of Canadian children aged 2-10

The purposes of this study were to model the development of indirect aggression among a nationally representative sample of 1,401 Canadian children aged 4 at T2, 6 at T3, 8 at T4 and 10 at T5, and to examine predictors of trajectory group membership from T1 (age 2) child, familial, and parenting variables. Using a semi-parametric group-based modeling approach, two distinct trajectories were identified: "increasing users" comprising of 35% of the sample and "stable low users" comprising of 65% of the sample. Using logistic regression analyses to distinguish these two groups, we found that for girls, more frequent, increasing use of indirect aggression was associated with prior prosocial and physically aggressive behavior, low SES and low parental social support at age 2. For boys, increasing use of indirect aggression was associated with prior parenting issues at age 2-inconsistency and less positive parent-child interactions. Although this study provides unique information regarding the early development of indirect aggression and its predictors, more longitudinal research is needed to fully understand its development.     

震后儿童创伤后应激障碍的症状网络演化

本研究借助网络分析方法,探讨儿童创伤后应激障碍(PTSD)症状的演化规律。以经历汶川地震的197名儿童为研究对象,在灾后4、29、40和52个月对其PTSD症状进行了历时4年的追踪测量。网络分析结果显示,闪回的中心性一直较高,而其他高中心性的症状随时间的推移发生了变化：侵入性想法和创伤线索引发生理性反应的中心性随时间推移呈上升趋势,线索引发情感反应和未来无望的中心性随时间推移呈下降趋势。本研究拓宽了学界对儿童PTSD症状学的认识, 并为建立灾后阶段性干预模式提供启示。     

流动儿童同伴侵害的特点及与内化问题的循环作用关系:一项追踪研究

本研究采用纵向设计,以北京市426名四、五年级流动儿童为被试,进行连续4次的追踪测查,考察流动儿童同伴侵害的特点及其与内化问题的动态相互作用关系。结果发现:(1)打工子弟学校流动儿童的同伴侵害与内化问题水平比公立学校流动儿童高;流动儿童的流动性越大,同伴侵害和内化问题越多。(2)控制了性别、年级、家庭社会经济地位(SES)和流动性后,从T1到T2,同伴侵害与孤独感为相互作用关系,且同伴侵害可以显著预测抑郁,但对社交焦虑的预测作用不显著,而从T2到T4,同伴侵害和3种内化问题的相互作用模式完全一致,即T2时的社交焦虑、抑郁和孤独感显著预测T3的同伴侵害,进而显著预测T4的社交焦虑、抑郁和孤独感。(3)抑郁、孤独感与同伴侵害的循环作用在两类流动儿童中具有较强的稳定性,而在社交焦虑和同伴侵害的模型中,打工子弟学校流动儿童的同伴侵害对社交焦虑的作用比公立学校流动儿童更大。可见,同伴侵害和内化问题呈循环作用关系,未来预防/干预研究可以聚焦于减少流动儿童的同伴侵害或内化问题的角度打破二者的恶性循环,帮助他们建立良好的人际关系,构建良性循环,促进他们的积极发展。     

高风险婴儿前瞻性纵向研究与孤独症谱系障碍早期识别

孤独症谱系障碍(Autism Spectrum Disorder, ASD)早期识别有助于早期诊断和早期干预的实施, 对于改善ASD儿童发育结果至关重要。高风险前瞻性纵向研究以高风险婴儿(ASD儿童的年幼同胞, 入组年龄小于12个月)作为主要研究对象, 通过对ASD高风险婴儿(24至36个月之间诊断为ASD的高风险婴儿)的早期发育轨迹的描绘和核心症状早期表现的识别, 为ASD早期识别提供了重要依据。未来可以增加被试数量、延长观察时间并密集观察时间点、关注伴发障碍、综合考虑遗传、环境和文化因素影响, 并结合早期干预研究进行深入探索。未来在中国开展相关研究具有重要的科学价值和临床意义。     

Global self-evaluations and perceived instability of self in early adolescence: A cohort longitudinal study

A cohort longitudinal design with four adjacent cohorts of students ( n = 1689) followed over two years was used to study key issues identified in the research literature on the development of self-evaluations in early adolescence. There was no clear relationship between age/grade and self-evaluations. We found no support for a "stressful periods" hypothesis with respect to self: Possible changes were very gradual and quite small. However, there was a consistent "relative age" effect implying that younger students within a grade had more negative self-evaluations. There were small but consistent sex differences in self-evaluations in favor of the boys; more detailed analyses of very negative self-evaluations suggested that the early adolescent years are the period in which a sex difference in depression related symptomatology begins to emerge. Finally, the usefulness of some kind of effect size measure and advantages and problems associated with a cohort longitudinal design were discussed.     

单亲家庭儿童相对剥夺感与心理适应的循环作用关系：一项追踪研究

本研究基于经典相对剥夺理论和发展情境理论, 采用纵向设计, 以湖北省某地区273名单亲家庭儿童为被试, 进行连续3次的追踪测查, 考察单亲家庭儿童相对剥夺感与心理适应的特点及其循环作用关系。结果发现: (1)单亲家庭男生的抑郁和孤独感水平比女生高; 贫困单亲家庭儿童的相对剥夺感、抑郁和孤独感水平比非贫困单亲家庭儿童高, 自尊水平比非贫困单亲家庭儿童低; (2)控制了性别、学段和家庭经济状况后, 在个体内水平上T1时的相对剥夺感显著负向预测T2时的心理适应, 进而显著负向预测T3时的相对剥夺感, 同时T2时的相对剥夺感也能显著负向预测T3时的心理适应; (3)相对剥夺感与心理适应的循环作用在不同家庭经济状况单亲儿童中存在显著差异, 贫困单亲家庭儿童的心理适应对其相对剥夺感的作用比非贫困单亲家庭儿童更大。可见, 单亲家庭儿童的相对剥夺感与心理适应存在循环作用关系, 即前测(T_n)的相对剥夺感会导致后测(T_n+1)的心理适应不良, 进而影响后测(T_n+2)的相对剥夺感, 研究结果对于单亲家庭儿童心理适应的干预具有一定启示意义。     

Developmental relations between ADHD symptoms and bullying perpetration and victimization in adolescence

It has previously been hypothesized that individuals with elevated attention deficit hyperactivity disorder (ADHD) symptoms are at greater risk of bullying perpetration and victimization. Using autoregressive latent trajectory models with structured residuals (ALT‐SR) and four waves (ages 11, 13, 15, and 17) of longitudinal data from the normative z‐proso study (n = 1526, 52% male), we evaluated the developmental relations between ADHD and bullying using both self‐ and teacher‐reported ADHD symptom data. Analyses suggested that ADHD symptoms primarily increase the risk of bullying perpetration, with a within‐person effect of ADHD symptoms on bullying perpetration symptoms identified across ages 13–15 (β = .13) and ages 15–17 (β = .19) based on self‐reported ADHD symptoms and a similar effect identified across ages 11–13 (β = .24) and 13–15 (β = .29) based on teacher‐reported inattention symptoms. There were also some indications of reciprocal effects and effects involving victimization that merit further exploration in future research. Results imply that the content of bullying intervention and prevention programs should take account of ADHD symptoms to ensure that those with elevated symptoms can benefit as much as their typically developing peers. This will involve addressing bullying perpetration that may reflect impulsive/reactive aggression and impaired social skills rather than instrumental aggression. Further, programs should go beyond classical curriculum/classroom‐based delivery to ensure that individuals with elevated ADHD symptoms can be successfully engaged.     

Sexist attitudes and beliefs during adolescence: A longitudinal study of gender differences

The aim of this study was to examine changes in sexist attitudes and beliefs in a group of Spanish adolescents over a period of three consecutive years, with specific attention being paid to gender differences. Participants were 279 students (mean age at first assessment of 12.10 years) who, in each of the three years, completed the Ambivalent Sexism Inventory and the Questionnaire on Attitudes towards Diversity and Violence. Longitudinal analysis showed that hostile sexism did not vary over time, whereas scores on benevolent sexism and on sexist beliefs and justification of violence all fell between the ages of 12 and 14, there being an equivalent decrease in boys and girls. Boys scored significantly higher than girls on hostile sexism, as well as on sexist beliefs. These results illustrate how sexist attitudes and beliefs change during adolescence and provide further confirmation that these variables show gender differences from an early age.     

The relationship between early life stress and working memory in adulthood: A systematic review and meta-analysis

ABSTRACT

Exposure to early life stress has been linked to impairment in cognitive functioning in adulthood. The aim of this study was to systematically review the literature on the relationship between early life stress and working memory, a central component of cognitive functioning. Database searches yielded 358 abstracts matching the search terms. Abstract screening followed by full-text review resulted in 26 publications suitable for inclusion, of which 23 were included in the meta-analysis. Results of the meta-analysis suggested exposure to early life stress was associated with poorer working memory. Even though there were a wide variety of working memory tasks used, this effect was significant for both phonological and visuospatial working memory tasks, and both visual and aural task presentation modalities. The effect was also found in samples with and without clinical psychopathology. This review provides recommendations for future research and implications for clinical practice.
