Stages in the development of aggressive behavior in early childhood

Primary manifestations of aggression appear in the behavior of children in the second half of the first year of life. The frequency of Occurrence of interpeer aggression increases with age, and reaches its maximum in the third year. The frequency of aggression may later decrease, but there are considerable individual differences. Changes a h Occur in the form in which aggression is manifested; its motivational background and associated elicitors; its direction, duration, timing, and other operational characteristics, and in the modes of its acquisition. A certain continuity may be traced, however, in any of these features and the development of aggression may be perhaps more adequately represented by the following sequence of developmental stage:

• 1 Stage of preaggressive behavior;
• 2 Stage of primary differentiation;
• 3 Stage of the appearance of the individual pattern of aggressive behavior;
• 4 Stage of secondary differentiation of aggression;
• 5 Stage of the beginning of the transition into covert behavior—internalization of aggression

These stages represent certain facets of the interaction between the changing behavioral performance of the child and herlhis social environment, and may be used for evaluating aggressive behavior in young children.     

Attachment and temperament in early childhood; implications for later behavior problems

In the context of a French validation study, the Child Behavior Checklist (CBCL) was administered to more than 3000 French speaking mothers of 5‐year‐old children. Scores were factor‐analyzed. Principal components analysis revealed four dimensions: externalizing and internalizing behavior problems, immaturity and somatoform disorders. Another sample of 40 mothers participated in a longitudinal study, filling in the CBCL when their children were 5 years old. These children had been observed previously in the Strange Situation (SSP) at 21 months. Several dichotomous variables derived from the SSP (e.g. secure versus insecure, proximal versus distal interaction with the mother, avoidant behavior) have been used as predictors of the four dimensions extracted from the CBCL. Hierarchical regressions showed that proximal behaviors with the mother, which reflect temperamental characteristics independently of the quality of attachment, predicted internalizing problems, whereas avoidance of the mother, or insecure–avoidant attachment, predicted internalizing as well as externalizing problems at 5 years of age. These results show that attachment and temperament, as assessed by the SSP, may each have specific implications for later behavior problems. Copyright © 2000 John Wiley & Sons, Ltd.     

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.     

Developmental changes in the relations between inhibitory control and externalizing problems during early childhood

Deficits in executive function, and in particular, reduced capacity to inhibit a dominant action, are a risk factor for externalizing problems (EP). Inhibitory control (IC) develops in the later preschool and early childhood periods, such that IC might not regulate EP in toddlers and younger preschoolers. Aggression was observed during peer play for 66 girls and 49 boys, from 2.75 to 6.00 years (M=4.14, S.D.=0.78). Mothers reported on children's IC and EP concurrently and 12 months later, and concurrent teacher reports of EP were also collected. Factor analysis supported aggregation of mother and teacher‐reported EP and observed physical aggression into one measure of externalizing difficulties. Mothers reported lower IC for children with more externalizing difficulties, and the inverse relation between IC and externalizing difficulties strengthened over the toddler, preschool and kindergarten periods. Similar relations between IC and EP were observed 12 months later, and increases in IC also predicted reductions in EP over 1 year. These data demonstrate that the preschool years are a dynamic period of developmental change in the relations between IC and EP. Copyright © 2010 John Wiley & Sons, Ltd.     

A longitudinal intergenerational analysis of executive functions during early childhood

Despite the importance of executive function (EF) in both clinical and educational contexts, the aetiology of individual differences in early childhood EF remains poorly understood. This study provides the first longitudinal intergenerational analysis of mother–child EF associations during early childhood. A group of children and their mothers (n = 62) completed age‐appropriate EF tasks. Mother and child EFs were modestly correlated by 24 months of age, and this association was stable through 48 months. Importantly, maternal–child EF associations were still robust after controlling for verbal ability (potential indicator of verbal/crystallized intelligence) and maternal education (correlate of socio‐economic status and verbal intelligence). Potential implications of these findings as well as underlying mechanisms of the maternal–child EF association (gene–environment interplay) are discussed.     

Evaluating the effect of educational media exposure on aggression in early childhood

Preschool-aged children (M = 42.44 months-old, SD = 8.02) participated in a short-term longitudinal study investigating the effect of educational media exposure on social development (i.e., aggression and prosocial behavior) using multiple informants and methods. As predicted, educational media exposure significantly predicted increases in both observed and teacher reported relational aggression across time. Follow-up analyses showed that educational media exposure also significantly predicted increases in parent reported relational aggression across more than a two year period. Results replicate and extend prior research that has demonstrated links between educational media exposure and relational aggression, but not physical aggression, during early childhood.     

Aggressive behavior among girls and boys during middle childhood: predictors and sequelae of trajectory group membership

Using longitudinal data spanning early elementary through middle school, aggression behavior trajectory groups were identified for boys and girls. Early elementary school predictors of trajectory group membership were examined as well as whether trajectory group predicted physical aggression, covert delinquency, and substance use in 9th grade. Semiparametric group modeling identified aggression behavior trajectory groups. We identified four aggression trajectory groups for both genders described as “not involved,” “low,” “moderate,” and “high.” Attention problems, family conflict, and low school commitment and attachment were predictors of membership in higher aggression groups for both boys and girls. Low family involvement and low parental education predicted membership in higher aggression groups for boys; while depression, low‐income status, and having a single parent predicted higher aggression group membership for girls. For both boys and girls, few risk predictors distinguished between the moderate and high aggression trajectories except that low school commitment and having a teen mother were significant predictors of being in the high group for girls, and low parental education and income were significant predictors of being in the high group for boys. Membership in the higher aggression trajectory groups predicted involvement in violent behaviors, covert delinquency, and substance use in 9th grade. Findings suggest that children who display an early trajectory of high levels of aggressive behavior are more likely to continue involvement in later problem behaviors. Second‐grade predictors suggest commonality of risk across genders and provide evidence of modifiable targets for preventive interventions. Aggr. Behav. 32:1–15. 2006. © 2006 Wiley‐Liss, Inc.     

Finding connections between spirituality and play for early childhood education

ABSTRACT

In an attempt to provide holistic education and care, expand the view of young children’s development to include the spiritual, and make connections with the found benefits of play for all areas of development, this article looks at 33 surveyed U.S. early childhood educators’ perceptions on nurturing spirituality through open-ended and free play. Data collected from the open-ended questions of an online survey were analyzed looking at 22 mentions of play as a mean to support spirituality. Findings show that 45.5% of surveyed teachers mentioned play as a way intentionally used in the classroom to nurture children’s spirituality. It is posed that developmentally appropriate approaches to early childhood education would be enhanced by including spirituality in their understanding of the child, as well as intentionally nurturing spirituality in educational settings, by providing free, child-centered, child-directed play and opportunities for children to experience spiritual moments, defined as feeling wonder, awe, joy, and inner-peace.     

Preschool Boys’ Development of Emotional Self-Regulation Strategies in a Sample At Risk for Behavior Problems

Little longitudinal research has been conducted on changes in children's emotional self-regulation strategy (SRS) use after infancy, particularly for children at risk. In this study, the authors examined changes in boys’ emotional SRS from toddlerhood through preschool. Repeated observational assessments using delay of gratification tasks at ages 2, 3, and 4 years were examined with both variable- and person-oriented analyses in a low-income sample of boys (N = 117) at risk for early problem behavior. Results were consistent with theory on emotional SRS development in young children. Children initially used more emotion-focused SRS (e.g., comfort seeking) and transitioned to greater use of planful SRS (e.g., distraction) by 4 years of age. Person-oriented analysis using trajectory analysis found similar patterns from 2 to 4 years, with small groups of boys showing delayed movement away from emotion-focused strategies or delay in the onset of regular use of distraction. The results provide a foundation for future researchers to examine the development of SRS in low-income young children.     

Factors in childhood that predict later criminal behavior

A follow-up study was conducted on the aggressive and delinquent behavior of an original sample of 220 pupils of two age groups. The subjects were 7 and 9 years old in 1978 when they were interviewed for the first time. The present paper focuses on predictors of the subjects' aggressive and criminal behavior in adolescence and in young adulthood. Four different groups of variables were chosen as possible predictive factors: 1) parental aggression, punitivity, and attitudes of rejection toward the child, 2) previous acts of aggression by the subjects, 3) the viewing of violence on television during childhood, and 4) aggressive, indifferent, and delinquent behavior in adolescence. Physical aggression in adolescence and the number of arrests and traffic violations in young adulthood were used as dependent variables. The analyses established that for the male subjects, the best predictor of physical aggression in adolescence was previous aggression, whereas for the female subjects the best predictor of physical aggression in adolescence was previous viewing of violence on television. The number of arrests in young adulthood was best predicted for the male subjects on the basis of previous aggression and viewing of violence on television. The best predictors of the number of arrests in young adulthood for the female subjects were, apart from previous aggression and viewing of violence on television, also aggressive and delinquent behavior in adolescence as well as parental aggression, punitivity, and attitudes of rejection. The results emphasize the importance of the atmosphere of socialization in childhood and previous aggressive behavior as significant predictors of physical aggression in adolescence and criminal behavior in young adulthood. © 1996 Wiley-Liss, Inc.     

Romantic relationships of young people with childhood and adolescent onset antisocial behavior problems

Using prospective longitudinal data from the Christchurch Health and Development Study, this paper examines the extent to which early onset, life course persistent and adolescent limited antisocial behavior problems place young people at risk of violent and unsatisfactory romantic relationships in early adulthood. Results revealed the presence of clear linear associations between the developmental timing of antisocial behavior and later partnership risks, with these risks including partner violence perpetration and victimization, interpartner conflict, and increased ambivalence about the relationship. Young people with childhood onset antisocial behavior problems reported higher rates of partnership difficulties than young people with adolescent limited antisocial behavior problems, while those with adolescent limited antisocial behavior reported higher levels of partnership difficulties than young people without a history of antisocial behavior problems. These associations persisted even after extensive control for a range of social, family, and individual factors that were correlated with the timing of antisocial behavior. Results highlight the importance of distinguishing between early and late onset antisocial behavior, and provide further support for existing life course models of the development of antisocial behavior problems in children and adolescents.     

Predictors of childhood trajectories of overt and indirect aggression: An interdisciplinary approach

The aim of this study was to advance our understanding of the development of aggression in boys and girls by testing a model combining insights from both evolutionary theory and developmental psychology. A sample of 744 children (348 girls) between six and 13 years old was recruited in schools with high deprivation indices. Half of the sample (N = 372; 40.1% girls) had received special educational services for behavioral and/or socio‐emotional problems. Two trajectories for overt aggression and two trajectories for indirect aggression were identified and binomial logistic regressions were used to identify environmental predictors and sex‐specific patterns of these trajectories. Results indicated that peer rejection predicted overt aggression and indirect aggression and that extraversion and male sex predicted overt aggression. The results also showed that interaction between parental practices and some child temperament traits predicted overt aggression (coercion and lack of supervision associated with extraversion or low effortful control) or indirect aggression (coercion and neglect associated with negative affect or low effortful control), and the absence of a father figure predicted high indirect aggression in girls.

     

Deception and subtypes of aggression during early childhood

A multi-informant study investigated the association between deception capacities and subtypes of aggression in a young early childhood sample (M = 44.65 months of age, SD = 13.39, N = 64). A newly developed teacher report of deception had appropriate psychometric properties (reliability, concurrent validity, and construct validity). Recently introduced observational methods of physical and relational aggression were reliable and valid with this sample. Findings indicated that both physical and relational aggression were associated with concurrent deception. For boys only, physical aggression uniquely predicted deception, controlling for the variance associated with relational aggression. In addition, relational aggression predicted deception above and beyond the role of physical aggression for the entire sample.     

儿童早期工作记忆与数学学习的关系

以往研究认为工作记忆对数学学习很重要,但是以往工作记忆和早期数学学习的关系研究结果并不一致。本研究运用元分析的方法回顾了33篇独立研究,含307项相关系数作为效应值,总被试量为42423名平均年龄3~8岁的儿童,旨在探讨工作记忆的3个主成分PL(语音回路)、VSSP(视觉空间画板)、CE(中央执行)与数学学习不同方面之间的关系,以及样本年龄对工作记忆和数学学习相关程度的调节作用。结果显示:工作记忆与数学学习确实存在强相关,工作记忆子成分中,CE与数学学习平均相关的程度最强。并且,CE与数学学习不同方面之间的相关程度不存在显著差异,PL、VSSP与数运算的相关程度比数概念更强,存在显著差异。样本年龄对CE、PL与数学学习之间相关关系存在显著调节作用,对VSSP与数学学习之间的相关关系不存在显著调节作用。文献梳理还发现,以往研究对数学学习的考察,大都聚焦数概念、数运算的内容,未来研究需要关注几何与空间、测量等方面内容。     

Beyond family‐level adversities: Exploring the developmental timing of neighborhood disadvantage effects on the brain

A growing literature suggests that adversity is associated with later altered brain function, particularly within the corticolimbic system that supports emotion processing and salience detection (e.g., amygdala, prefrontal cortex [PFC]). Although neighborhood socioeconomic disadvantage has been shown to predict maladaptive behavioral outcomes, particularly for boys, most of the research linking adversity to corticolimbic function has focused on family‐level adversities. Moreover, although animal models and studies of normative brain development suggest that there may be sensitive periods during which adversity exerts stronger effects on corticolimbic development, little prospective evidence exists in humans. Using two low‐income samples of boys (n = 167; n = 77), Census‐derived neighborhood disadvantage during early childhood, but not adolescence, was uniquely associated with greater amygdala, but not PFC, reactivity to ambiguous neutral faces in adolescence and young adulthood. These associations remained after accounting for several family‐level adversities (e.g., low family income, harsh parenting), highlighting the independent and developmentally specific neural effects of the neighborhood context. Furthermore, in both samples, indicators measuring income and poverty status of neighbors were predictive of amygdala function, suggesting that neighborhood economic resources may be critical to brain development.     

早期儿童数学学习与执行功能的关系

执行功能是个体对复杂的认知活动的自我调节和以明确目标为导向的活动过程, 对早期儿童的数学学习起着重要的作用。早期儿童数学学习与执行功能呈显著正相关, 执行功能是儿童数学学习的重要认知加工机制。早期儿童执行功能和数学学习之间存在着相互预测的关系, 执行功能可以预测数学成绩, 数学成绩可以预测执行功能。高质量的早期数学教育可能具有发展儿童执行功能和数学能力的双重价值。未来研究可以明确执行功能的界定和统一测量工具, 提供更可靠的证据证明早期儿童执行功能与数学能力的因果关系, 以及进一步探究语言、数学以及执行功能三者之间的关系。
