地震后青少年创伤后应激障碍的潜在结构分析

为考察地震后青少年创伤后应激障碍（PTSD）的潜在症状结构,本研究采用儿童创伤后应激障碍症状量表和儿童抑郁量表,对汶川地震一年后的746名中学生进行调查。利用验证性因素分析对竞争模型进行比较,结果发现包括侵入性、回避性、麻木性、精神痛苦性唤起和焦虑性唤起等5个症状的PTSD精神痛苦性唤起模型显著优于DSM-IV的PTSD模型、4维情感麻木模型和4维精神痛苦模型。效度分析的结果发现,PTSD精神痛苦性唤起模型具有良好的外部区分效度。所有结果均表明PTSD精神痛苦性唤起模型在汶川地震后青少年群体中具有良好的适用性,可以作为判定震后青少年PTSD症状的有效标准。     

儿童青少年协作促进的发展

旨在考察不同年龄的个体, 在不同回忆序列和学习材料上协作促进的发展情况。采用3(回忆序列:协作—个人—个人〔CII〕、个人—协作—个人〔ICI〕、个人—个人—个人〔III〕)× 5(年龄:9、11、14、17、20)× 2(材料:图片、文字)的被试间设计。结果发现:(1)各年龄个体在CII和ICI两种回忆序列上均出现了协作促进, 且两种序列条件下被试的最终个人回忆成绩无差异;(2)另外, 17岁个体的协作促进量显著高于9岁、11岁、14岁和20岁, 其他各年龄之间无差异;(3)图片和文字的协作促进量无差异。这说明小组协作回忆的顺序对协作促进没有太大影响, 17岁个体协作促进的效果最好。     

Arnold Gesell and the Maturation Controversy

This article examines the work of Arnold Lucius Gesell and argues that he not only paved the way for contemporary research in motor development, but that he and colleagues anticipated fundamental issues about growth that must be addressed by psychologists and neuroscientists who are committed to the advancement of developmental science. Arnold Lucius Gesell was a pioneer in developmental psychology when the field was in its infancy. He worked diligently for the rights of physically and mentally handicapped children to receive special education that would enable them to find gainful employment. Gesell's writings in books and popular magazines increased public awareness of and support for preschool education and better foster care for orphans. Despite these achievements, many of his successors have questioned his views about infant development. Developmental psychologists have criticized Gesell for proposing a stage theory of infant growth that has fallen into disfavor among contemporary researchers. His conception of development as a maturational process has been challenged for allegedly reducing complex behavioral, perceptual, and learning processes to genetic factors. The author rejects this overly simplistic interpretation and contends that Gesell's work continues to stand the test of time.     

Modularity and hierarchical organization of action programs in children's acquisition of graphic skills

The organization of actions is based on modules in memory as a result of practice, easing the demand of performing more complex actions. If this modularization occurs, the elements of the module must remain invariant in new tasks. To test this hypothesis, 35 children, age 10 yr., practiced a graphic criterion task on a digital tablet and completed a complex graphic task enclosing the previous one. Total movement and pause times to draw the figure indicated skill acquisition. A module was identified by the variability of relative timing, pause time, and sequencing. Total movement to perform the criterion task did not increase significantly when it was embedded in the more complex task. Modularity was evidenced by the stability of relative timing and pause time and sequencing. The spatial position of new elements did not perturb the module, so the grammar of action may still have been forming.

青少年药物滥用的防治

随着社会转型所带来的生活方式多元化,青少年药物滥用现象,在威胁着青少年身心健康的同时,也破坏了社会的和谐与发展.一般来说,其形成原因包括自身、家庭、学校和社会等多种因素,因而,预防和解决青少年药物滥用问题,就需要建立一套涉及多个层面的防治体系.     

Parenting Stress and Childhood Psychopathology: An Examination of Specificity to Internalizing and Externalizing Symptoms

The purpose of this study was to examine if specificity exists between three factors of parenting stress (i.e., parental distress, parent–child (PC) dysfunctional interactions, and difficult child) and childhood internalizing and externalizing symptoms. The incremental validity of parenting stress beyond parental psychopathology was also examined. The sample was drawn from families of children aged 5–17 (N = 300), who sought treatment for their child from a community mental health clinic. Results indicated that the PC dysfunctional interactions factor showed specificity to internalizing symptoms when controlling for parental psychopathology. Parental distress did not show specificity or incremental validity and the difficult child factor was associated with both internalizing and externalizing symptoms when controlling for parental psychopathology. The influence of age, gender, and ethnicity on these associations is also presented, and findings are discussed in terms of how the results add to understanding the specific relations between parenting stress and child and adolescent symptoms.     

Making a life worth living: neural correlates of well-being

Despite the vast literature that has implicated asymmetric activation of the prefrontal cortex in approach-withdrawal motivation and emotion, no published reports have directly explored the neural correlates of well-being. Eighty-four right-handed adults (ages 57-60) completed self-report measures of eudaimonic well-being, hedonic well-being, and positive affect prior to resting electroencephalography. As hypothesized, greater left than right superior frontal activation was associated with higher levels of both forms of well-being. Hemisphere-specific analyses documented the importance of goal-directed approach tendencies beyond those captured by approach-related positive affect for eudaimonic but not for hedonic well-being. Appropriately engaging sources of appetitive motivation, characteristic of higher left than right baseline levels of prefrontal activation, may encourage the experience of well-being.
