Network structure reveals clusters of associations between childhood adversities and development outcomes

Exposure to childhood adversity is common and associated with a host of negative developmental outcomes. The most common approach used to examine the consequences of adversity exposure is a cumulative risk model. Recently, we have proposed a novel approach, the dimensional model of adversity and psychopathology (DMAP), where different dimensions of adversity are hypothesized to impact health and well‐being through different pathways. We expect deprivation to primarily disrupt cognitive processing, whereas we expect threat to primarily alter emotional reactivity and automatic regulation. Recent hypothesis‐driven approaches provide support for these differential associations of deprivation and threat on developmental outcomes. However, it is not clear whether these patterns would emerge using data‐driven approaches. Here we use a network analytic approach to identify clusters of related adversity exposures and outcomes in an initial study (Study 1: N = 277 adolescents aged 16–17 years; 55.1% female) and a replication (Study 2: N = 262 children aged 8–16 years; 45.4% female). We statistically compare our observed clusters with our hypothesized DMAP model and a clustering we hypothesize would be the result of a cumulative stress model. In both samples we observed a network structure consistent with the DMAP model and statistically different than the hypothesized cumulative stress model. Future work seeking to identify in the pathways through which adversity impacts development should consider multiple dimensions of adversity.     

对以类别为基础的归纳推理的几种理论模型的评价

当前关于以类别为基础的归纳推理理论模型大致可以分为两种：强调相似性作用的归纳推理的理论模型和强调知识作用的归纳推理的理论模型。前者能较好的解释人们在知识贫乏领域的归纳推理现象,而后者则能够较好的解释人们在知识丰富领域的归纳推理现象。     

早期音乐暴露增强大鼠分辨声音时程的作业能力

用声一电防御性条件反射的方法。对42只具有不同早期听觉经验的大鼠的声音时程分辨行为进行了观察和比较研究。实验结果表明：大鼠具有一定的分辨声音时程的作业能力,出生后早期的音乐暴露,能够明显增强大鼠分辨声音时程的作业能力。     

团队作业特征研究现状与展望

团队作业特征是团队有效性模型中的重要输入变量,是团队绩效差异的贡献因素。作业特征在个体与团队层面的相关理论基础表明,团队作业特征包括技能多样性、作业同一性、作业重要性、反馈、自主性、作业互依性、作业复杂性七个核心要素。以此为基础介绍了作业特征在个体与团队层面的相关效应研究;团队作业特征模型测量、作业特征作用机制、作业特征要素的深入研究则可作为未来研究的重点     

精神分裂症的潜伏抑制动物模型

精神分裂症动物模型的建立,是当前研究精神分裂症的神经生物学机制以及开发新的抗精神病药物的一个重要课题。文章系统地阐述了以潜伏抑制为行为模式的精神分裂症动物模型的理论以及神经机制,并重点介绍了精神分裂症的潜伏抑制动物模型的建立方法,包括（1）调节某些与精神分裂症相关的中枢神经递质的传递活动;（2）对与精神分裂症有关的中脑-伏隔核神经环路进行结构损伤或药物性干预;（3）在发育早期给予免疫刺激或环境应激     

应用多质-多评价者程序对评定误差的分析

应用多质 -多评价者矩阵分析绩效评定中两种常见误差 -光环效应和自我中心效应。以足球运动员为被评价者 ,以关键事件技术为职务分析方法获得绩效评定特质。以 45名被试观看足球比赛后评定的各职务特质间的相关为基础相关系数 ;两组共 8名被试观看录像剪辑并采用两种评价标准作评价 ,计算各特质评定结果间的相关系数 ,并整理为多质 -多评价者矩阵。结果表明 ,多质 多评价者矩阵可以直观显示光环效应 ;评价者在不同职务的个别特质上表现出自我中心效应。     

拥挤、抢食对自发性高血压大鼠发病的影响及作用机制的探讨

社会、心理压力与疾病的发生、发展及转归有着密切的联系。而社会、心理压力为什么会导致一些心身疾病的发生?为什么可使一些疾病加重?尚无满意答案。本文选用自发性高血压大鼠(SHR),在实验室应激的条件下,对比观察了动物的血压,并对其作用机制进行了初步探讨。发现:心理紧张状态可以导致有高血压遗传素质的SHR提前发病,而且可使病情不断加重;应激后SHR血浆神经递质(NE.E)和神经肽类物质(VIP)均明显增高。表明原发性高血压病的发生、发展与社会心理因素关系密切。     

Near-death experiences among survivors of the 1976 Tangshan earthquake

We interviewed 81 survivors of the severe earthquake in Tangshan in 1976 and found that 32 (40 percent) reported near-death experiences (NDEs) as measured by Greyson's (1983) NDE Scale. The great majority of these NDEs were of the cognitive and transcendental types, and our observations were somewhat different from those of Greyson (1985) in the United States and of Pasricha and Stevenson (1986) in India. These differences suggest that the components, sequences, and types of NDE might differ with race, religion, psychological and cultural background, and kind of near-death event.
