童年中晚期同伴侵害对儿童心理社会适应影响的纵向分析

采用间隔两年的纵向设计, 通过对1767名儿童的同伴侵害以及孤独、抑郁、攻击、行为不良、同伴接纳、同伴拒绝等心理社会适应指标进行调查, 综合运用变量定向的方法和个体定向的方法考察了童年中晚期儿童心理社会适应发展的结果模式, 以及同伴侵害对儿童心理社会适应发展的影响。结果发现, (1)身体侵害、关系侵害与心理社会适应各指标存在显著的即时与纵向相关关系。(2)儿童心理社会适应结果表现为内化问题、外化问题、同伴拒绝、正常发展4种模式。(3)判别分析显示, 9岁的同伴侵害(主要为身体侵害)能预测同伴拒绝、外化问题适应结果模式, 11岁的同伴侵害(主要为关系侵害)能预测内化问题、同伴拒绝适应结果模式。这些结果表明同伴侵害与儿童心理社会适应间的联系具有异质性, 并且先前和当前的侵害经历以及不同类型的侵害与心理社会适应间的联系因适应领域的不同而存在差异。     

COMT基因rs6267多态性与母亲教养行为对青少年身体攻击和关系攻击的交互作用

遗传与环境如何交互作用影响儿童青少年的攻击行为是当前攻击研究中的重要前沿课题之一。近年来, 分子遗传学关于人类攻击的研究已拓展到对不同攻击亚类(身体攻击和关系攻击)的遗传基础的探讨。本研究运用问卷法与DNA分型技术, 对1258名儿童进行为时4年(四年级—七年级)的追踪调查, 考察COMT基因rs6267多态性与母亲教养行为对青少年身体攻击和关系攻击的交互作用以及性别在其中的调节作用。结果发现, COMT基因rs6267多态性与母亲教养行为仅交互作用于男青少年的身体攻击, 母亲教养行为显著预测GG 基因型男青少年的身体攻击, 但对T等位基因男青少年身体攻击的预测作用并不显著。COMT基因rs6267多态性与母亲教养行为对青少年关系攻击的交互作用不显著。本研究结果表明, 身体攻击和关系攻击具有不同遗传基础和发生机制。     

联结竞争对听写困难儿童形音联结编码的影响

听写困难是一种发生率较高的儿童学习障碍现象。听写困难的认知机制,主要包括语音加工缺陷、字形表征缺陷以及形音联结编码缺陷。本研究通过两个实验,考察了整字语音竞争和部件语音竞争,对听写困难儿童形音联结编码的影响。结果发现,在不同条件下,听写困难儿童的形音联结水平都落后于正常儿童;整字语音竞争显著干扰了正常儿童的形音联结编码,但对听写困难儿童的影响并不明显;与之相反的是,部件语音竞争对听写困难儿童的干扰更为明显。研究结果支持听写困难儿童的形音联结编码缺陷理论。在此基础上,听写困难儿童的形音联结较少受到整字语音的竞争干扰,但更容易受到部件语音的竞争干扰,这可能是因为,他(她)们的整体字形加工或表征存在缺陷,导致原生字字形和语音信息难以被激活,以及合体字的部件信息得到更多的加工所致。     

团队断裂带:团队多样性研究的新视角——从单一指标到多重指标

团队断裂带是指团队基于多种团队构成特征而分化为几个具有本身同质、彼此异质的差异性子团队的"虚拟的分割线"。本研究从构成、状态、测量及作用机理方面阐述了团队断裂带最新的研究进程及结果,并在此基础上建构了团队断裂带的研究框架。最后总结未来的研究应当在团队断裂带的调节机制、团队成员退出加入的动态机制、社会分类断裂带和信息相关断裂带的交互作用及团队情境对断裂带的影响等方面做进一步的探索。     

Changing your mind about things unseen: Toddlers' sensitivity to prior reliability

The goal of this research was to investigate the extent to which young children use the past reliability of another person’s statements to make inferences about the accuracy of that person’s claims about a hidden toy. When children interacted with a previously reliable speaker, both 30- and 36-month-olds searched in the new location of the toy, in line with the speaker’s statement. When children interacted with an unreliable speaker, the 36-month-olds were less likely to rely on her false statement and instead searched either in the original location of the toy or in a neutral location. The 30-month-olds, however, searched in the location indicated by the speaker even when the speaker was unreliable. These results show that by 36 months of age, children begin to use reliability in processing a speaker’s episodic claims and can flexibly update their representations of absent objects depending on the reliability of the speaker.     

Traumatic Stress and Religion: Is there a Relationship? A Review of Empirical Findings

Based on a history of close conceptual link, empirical studies are beginning to accumulate that investigate the relationship between trauma and religion. A review of empirical studies that examined the relationship between religion/spirituality and PTSD showed mixed findings (n = 11). Though the direction of association varied among studies, all but one study reported significant associations between the two. Factors that might have contributed to the mixed findings are discussed (e.g., measurements, research design). Overall, these results appear to be encouraging toward confirming the conceptual link between religion and trauma. Further research investigating the direction of causation and possible moderators of the association may contribute to a better understanding of the relationship between trauma and religion.Yung Chen, Ph.D. was a research fellow at Duke University Medical Center, and is now an Assistant Professor in the Department of Behavioral Sciences and Leadership at the United States Military Academy at West Point.Harold Koenig, M.D. is a Professor of Psychiatry and Behavioral Sciences at Duke University Medical Center.     

肺动脉血栓栓塞症与凝血纤溶系统失衡

在生理状态下,凝血与纤溶处于动态平衡状态;当这种平衡失衡时,便可招致出血不止或形成栓塞。体内某些抗凝途径的蛋白缺陷会使机体处于高凝状态而导致静脉血栓栓塞性疾病(VTE),已经报道有多种栓塞因素与VTE的发生有关;人们通常认为,慢性栓塞性肺动脉高压(CTE-PH)是静脉系统栓子反复脱落至肺动脉所致,很自然的会想到CTE-PH的发病可能与以上多种栓塞因素有关,然而,目前研究更倾向于CTEPH和VTE并没有直接的关系或者说是两个独立的疾病。     

构建“医患沟通学”的思考与探索

中国医患关系紧张的原因涉及观念、国情、法制、政策、制度、医疗方式等。构建“医患沟通学”有重要的意义:医患迫切需要恢复和谐信任关系;新型医学模式变革、医学人才的培养及医学发展等更需要搭建“医患沟通”新的研究平台,并完善其理论。医患沟通实践与研究的过程,就是临床教师、医务卫生人员提高医学人文素质和实践能力的新途径。
