Latent Classes of Psychiatric Symptoms Among Chinese Children Living in Poverty

Describing co-occurring symptom patterns among children in nonwestern contexts may have important implications for how emotional and behavior problems are defined, conceptualized, studied, and ultimately prevented. A latent profile analysis (LPA) was conducted on the co-occurring psychiatric symptoms of 196 Chinese children living in poverty. Child depression, anxiety, aggression, and self-esteem scores were used as indicators in the LPA. Three classes of symptoms best described the symptom presentations of children in this study. Ninety-one percent of the youth in the sample were assigned to a class without clinically significant elevations on any symptom index. Six percent fell into an externalizing class, and 3% were assigned to a class with elevated internalizing symptoms. The three classes met empirical criteria for distinctiveness and were validated against parent- and child-rated family characteristics and resources. Children in the externalizing class were more likely to experience harsh and neglectful parenting and their parents were more likely to report avoidant coping styles. In addition to some parenting behaviors (overprotection and low parental support), internalizing symptoms were uniquely associated with low levels of education, housing, economic, and social resources. Implications for preventive interventions are discussed.     

Neural correlates of comprehension and production of nouns and verbs in Chinese

This paper reports a conjunction analysis between semantic relatedness judgment and semantic associate generation of Chinese nouns and verbs with concrete or abstract meanings. The results revealed a verb-specific task-independent region in LpSTG&MTG, and task-dependent activation in a left frontal region in semantic judgment and the left SMG in semantic associate production. The observation of word class effects converged on Yu, Law, Han, Zhu, and Bi (2011), but contrasted with null findings in previous reports using a lexical decision task. While word class effects in the left posterior temporal cortices have been described in previous studies of languages with rich inflectional morphology, the significance of this study lies in its demonstration of the effects in these regions in a language known to have little inflectional morphology. In other words, differential neural responses to nouns and verbs can be observed without confounding from morphosyntactic operations or contrasts between actions and objects.     

受灾情况和复原力对地震灾区中小学生创伤后应激反应的影响

进行心理援助之前,对都江堰安龙镇某九年制学校学生进行受灾情况、复原力和创伤后应激反应的测查,目的在于探讨受灾情况和复原力对中小学生创伤后应激反应的独立和交互影响,并为心理援助活动提供参考。结果表明：（1）在震后一个半月之时,该校有32%的学生出现较严重的创伤后应激反应;（2）有亲人遇难的学生在闯入、回避、警觉以及创伤后应激反应的总分上均显著高于无亲人遇难的学生;（3）复原力中的积极认知和信任两个维度对降低学生创伤后应激反应有比较大的作用;（4）复原力中的社会支持维度能够缓冲亲人遇难带来的负向影响     

自信社会认知的自我-同学目标比较分析

本研究对大学生自信社会认知进行计量和非计量的自我一同学目标比较.自信水平报告和自信社会比较的分析表明:自信水平报告自我目标低于同学目标;自信水平报告的自我一同学比较与自我一同学自信社会比较之间并不完全一致;积极的比较关系和不稳定的自信反身意识是大学生自信水平社会认知的特点.自信内容重要性的分析表明:被肯定的自信特征内容包括自我调节、自我完善及有所作为等,被否定的则包括外貌仪表、伴侣家庭、未知领域及对问题的思考等.同时,自我目标自信内容结构相比同学目标更为分化和均衡,同学目标结构是相对简约便利.整个研究表明,两类目标具有不同的自信社会认知模式.

潜变量交互效应模型标准化估计中的检验问题

讨论了潜变量交互效应模型是否能直接用统计软件输出的原始估计的t值对模型的标准化估计进行检验的问题,详细介绍了标准化估计的t值计算及其难点,用Bootstrap方法算出标准化估计的标准误和相应的t值（记为t_bs）,并将其与原始估计的t值比较.结果发现,当原始估计t值超过3时,无论用t值还是用t_ bs检验,结果都是显著,即可以使用t值进行检验.而当t值不超过3时,与t_bs很接近,也可以用t值检验,但t值在临界值附近（例如1.5 ～2.5）时,最好还是使用Bootstrap法计算t_bs进行检验.     

4～6岁儿童直接推理能力及策略的实验研究

采用定量与定性相结合的研究方法,对4－6岁儿童的直接推理能力进行了实验研究,结果表明：（1）学前儿童萌发了评议条件下的直接推理能力,但年龄发展效应并不明显;（2）对于学前儿童而言,否定前提下的直接推理并不比肯定前提的难。但是,如果进行了反义词的转换,同样的任务,却增加了肯定前提下直接推理的任务难度,而对否定前提下的直接堆理没有影响;（3）学前儿童在直接推理时多种策略并存,随着年龄的增长,有效策略的生成能力有了明显的提高,但有效策略的使用能力并没有与有效策略的生成能力同步发展,而是表现为落后的趋势。     

Individual differences in false memory from misinformation: Cognitive factors

This research investigated the cognitive correlates of false memories that are induced by the misinformation paradigm. A large sample of Chinese college students (N=436) participated in a misinformation procedure and also took a battery of cognitive tests. Results revealed sizable and systematic individual differences in false memory arising from exposure to misinformation. False memories were significantly and negatively correlated with measures of intelligence (measured with Raven's Advanced Progressive Matrices and Wechsler Adult Intelligence Scale), perception (Motor-Free Visual Perception Test, Change Blindness, and Tone Discrimination), memory (Wechsler Memory Scales and 2-back Working Memory tasks), and face judgement (Face Recognition and Facial Expression Recognition). These findings suggest that people with relatively low intelligence and poor perceptual abilities might be more susceptible to the misinformation effect.
