幼儿的情绪表现规则知识发展及其与家庭情绪表露、社会行为的相关研究

通过幼儿情绪表现规则知识的访谈、家庭情绪表露问卷和幼儿社会行为评估问卷调查,考察了112名3～6岁幼儿情绪表现规则知识的发展及其与家庭情绪表露、社会行为的关系。结果表明:(1)幼儿的表情调节知识存在显著的年龄差异,大班幼儿比小班幼儿具有更高的表情调节知识、更倾向于掩饰消极情绪;(2)幼儿的表情调节知识与情绪表达的人际支持、工具支持的结果期望存在显著正相关,即幼儿掩饰消极情绪是因为预期情绪表达不会得到他人理解和帮助;(3)幼儿报告面对父母同伴教师不同在场者时具有不同的情绪体验,且幼儿的人际支持结果预期存在年龄和在场者的交互作用;(4)家庭情绪表露与幼儿的人际支持的结果预期存在显著正相关、与工具支持的结果预期存在显著负相关;(5)倾向于掩饰消极情绪的幼儿表现出更多的亲社会行为,认为表达消极情绪会带来不良结果的幼儿表现出更多的害羞退缩行为。     

Changes in maternal ratings of children's overt and covert antisocial behavior

Maternal ratings of overt and covert forms of aggression were collected for two samples of children ranging in age from 2 through 12 years. It was hypothesized that longitudinal analyses would show the slope scores for these two forms of aggression to be quite different from each other. The data were consistent with this hypothesis. An effort was made to find alternative explanations for the negative slope for overt antisocial behavior. Alternatively, it was hypothesized that the more extreme cases would not show this negative slope. It was also hypothesized that careful examination of intraindividual curves would identify a significant number of individuals growing from normal to clinical levels of overt antisocial behavior. The findings led to the rejection of both alternative hypotheses. It was hypothesized that overt and covert scores would correlate significantly for first grade boys. It was also assumed that both covert and overt scores would show moderate stability over the 5‐year interval. The findings were consistent with both of these hypotheses. Aggr.

慢性应激诱导的抑郁大鼠纹状体par-4基因的表达

为研究慢性温和应激诱导的抑郁大鼠纹状体内前列腺凋亡反应蛋白(prostate apoptosis response-4, par-4)的表达, 及甲基化是否参与par-4基因表达的调控, 将10周龄大鼠随机分为实验组和对照组, 实验组接受慢性温和应激, 对照组不接受实验性处理。于大鼠13周龄时, 采用强迫游泳、糖水偏爱测验测定大鼠的抑郁水平, 以实时定量PCR检测纹状体par-4及多巴胺D2受体(Dopamine receptor D2, DRD2) mRNA表达水平, 免疫印迹法检测纹状体par-4蛋白质表达水平, 用亚硫酸盐测序法检测par-4基因启动子区甲基化水平。结果发现, 与对照组大鼠相比, 实验组大鼠漂浮时间延长, 糖水偏爱率降低, 脑纹状体par-4、DRD2 mRNA及par-4蛋白质表达水平均降低, par-4基因启动子区甲基化水平两组差异不显著。提示慢性温和应激诱导大鼠产生了抑郁样行为, 并能抑制纹状体par-4基因的表达, 而基因甲基化可能并不参与其调控机制。     

Approaching math increases math = me and math = pleasant

In two studies, we examined the effect of extensive practice in approaching math on implicit identification with math, implicit math attitudes, and behavior during a math test. The results from Study 1 demonstrated that women trained to approach math showed more identification with and positive implicit attitudes toward math than women trained to avoid math. Notably, this latter pattern of findings was only evident for women low in initial identification with this field. The results from Study 2 replicated these findings by showing that women who were initially low in math identification and trained to approach math showed more implicit identification with math and attempted more items on a math test than women trained to respond to math in a neutral way. The implications of these findings for current theorizing on the gender gap in women’s representation in math related careers are discussed.     

Predicting Early Sexual Activity with Behavior Problems Exhibited at School Entry and in Early Adolescence

Youth who initiate sexual intercourse in early adolescence (age 11–14) experience multiple risks, including concurrent adjustment problems and unsafe sexual practices. The current study tested two models describing the links between childhood precursors, early adolescent risk factors, and adolescent sexual activity: a cumulative model and a meditational model. A longitudinal sample of 694 boys and girls from four geographical locations was utilized, with data collected from kindergarten through high school. Structural equation models revealed that, irrespective of gender or race, high rates of aggressive disruptive behaviors and attention problems at school entry increased risk for a constellation of problem behaviors in middle school (school maladjustment, antisocial activity, and substance use) which, in turn, promoted the early initiation of sexual activity. Implications are discussed for developmental models of early sexual activity and for prevention programming.

Binge drinking and violence against intimate partners in Russia

This study is the first to provide information on the association between intimate partner violence (IPV) and binge drinking among Russian university students. Using data from 500 (58% female) university students from the four Russian sites of the International Dating Violence Study, we found gender differences in rates of IPV perpetration and in the association between binge drinking and IPV. Specifically, more females than males perpetrated IPV, and the associations between binge drinking and IPV were stronger for the female students than for the male students. In addition, antisocial traits and behavior (ATSB) were significantly related to both binge drinking and IPV perpetration for males and females. For males, the relatively weak associations between binge drinking and IPV perpetration disappeared once ASTB was accounted for. For females, the relationship decreased but remained significant when ATSB was statistically controlled. Path analyses confirmed that this pattern of relationships would be consistent with ATSB serving as a partial mediator between binge drinking and IPV perpetration. However, other alternative mediation and moderation models for the relationships between binge drinking, IPV perpetration, and ATSB could not be ruled out with this one-wave correlational study.     

Preliminary evidence that specific candidate genes are associated with adolescent-onset antisocial behavior

Though initially conceptualized as resulting from peer imitation of child-onset or life-course-persistent youth [Moffitt, 1993], there is mounting evidence from twin studies that adolescent-onset or adolescent-limited antisocial behavior may also be genetically influenced. This study sought to provide preliminary molecular genetic evidence in support of these findings. We further evaluated whether genetic associations varied between behavioral subtypes of ASB (i.e., physical aggression and nonaggressive rule-breaking), given that only the latter has been found to characterize adolescent-onset ASB. The sample consisted of 211 undergraduate men of European-American ancestry. Three polymorphisms with theoretical and/or empirical ties to ASB or related traits (i.e., tryptophan hydroxylase-A218C, 5HT(2A) His452Tyr, and the DAT1 variable nucleotide tandem repeat) were genotyped. Analyses revealed that two of the three polymorphisms (i.e., His452Tyr and DAT1) were associated with adolescent ASB. Moreover, these associations appeared to be specific to the nonaggressive, rule-breaking form of ASB, and did not extend to physical aggression, further supporting ties to adolescent ASB in particular. Such results thus constructively replicate earlier findings of genetic influence on adolescent ASB. They also offer preliminary evidence that the genetic processes underlying aggressive and nonaggressive antisocial behavior may be (at least partially) distinct.     

The Role of Neurobiological Deficits in Childhood Antisocial Behavior

ABSTRACT— Childhood-onset antisocial behavior is an important predictor of chronic and serious forms of antisocial behavior in later life. Both biological and social factors are involved in the development of abnormal behavior. We examine the underlying role of stress-response systems in the link between early social adversity and juvenile antisocial behavior, and propose that children with genetically and/or perinatally based neurobiological deficits have problems in activating these systems and therefore experience difficulties in regulating affect and behavior. Underactivity or attenuated reactivity of the stress-response systems may predispose antisocial individuals to seek out stimulation or take risks, and thereby explain deficits in learning and socialization. Further investigations of neurobiological functioning in antisocial children might not only indicate which children are more likely to persist in behaving antisocially but also guide the development of new interventions.     

Mechanisms by Which Childhood Personality Traits Influence Adult Well-Being

ABSTRACT— Children's personality traits have enduring effects that shape adult well-being. In particular, childhood conscientiousness influences core aspects of adult well-being: health, friendships, and mastery. Research is now examining the mechanisms by which early personality traits initiate and sustain particular life paths. These include mediating and moderating mechanisms that may operate during critical developmental periods or may build cumulatively over time. Future research would benefit from testing theoretically derived mechanisms for different traits and examining variables as they change over time, using both short- and long-term longitudinal designs over different life stages.
