表观遗传修饰在应激诱发抑郁症中的作用

应激可以对个体的生理和行为产生负面影响, 甚至导致抑郁症, 但病因机制尚不清楚。近年来许多研究发现应激导致的表观遗传修饰变化影响抑郁症的发生。表观遗传是指DNA序列不发生变化, 但基因表达却发生了可遗传的改变。应激引起的HPA轴、单胺类递质、BDNF三个方面的表观遗传修饰的变化, 在抑郁症发生中发挥重要作用。最后提出了目前表观遗传机制研究的局限性和未来研究热点。     

民族文化认同与大学生职业成熟度的关系及其心理机制

为考察大学生民族文化认同与职业成熟度的关系及其内在心理机制,本研究采用多民族青少年文化认同问卷、大学生生涯自我效能感量表和大学生职业成熟度量表对4292名在校大学生进行测查,结果发现：（1）大学生的主流文化认同、民族文化认同、生涯自我效能感和职业成熟度之间具有明显的正相关;（2）主流文化认同--生涯自我效能感在民族文化认同与职业成熟度之间起链式中介作用;（3）生涯自我效能感中介民族文化认同与职业成熟度的关系在男生样本中不显著而在女生样本中显著;主流文化认同、生涯自我效能感分别单独中介民族文化认同与职业成熟度的关系在汉族大学生样本中为部分中介,而在少数民族大学生样本中为完全中介。     

组织中的高质量联结

组织中的高质量联结(HQC)指工作中短期的积极互动关系。它能使交往双方体验到活力、积极关照与相互交融, 并具有高情感承载力、关系张力与联结力三个特征。目前, HQC已成为积极组织行为学关注的热点问题之一, 它不仅对个体生理健康、工作态度、学习行为具有积极影响, 还能通过组织过程、高管团队的决策与张力、团队创新力作用于组织。而认知、情感和行为机制是构建与强化HQC的重要方法。未来HQC研究需要对其影响因素、构建与强化机制间关系做进一步讨论。     

儿童早期"心理理论"发展研究中的几个基本问题

儿童"心理理论"的发展研究是当今发展心理学中最活跃的领域之一.近年来,该领域的研究重点已逐渐由一般的发展描述,转向关于"心理理论"的缘起与发展机制的研究.由此,有许多密切相关的关于早期"心理理论"发生发展及其评估的基本问题,横亘于研究者面前,迄今仍悬而未决,并引发诸多争议.如何解决这些问题并理顺它们之间的关系,将极大地影响着该领域今后的研究进展.     

Effect of a novel motion desensitization training regime and controlled breathing on habituation to motion sickness

To study whether controlled breathing, known to ameliorate motion sickness, speeds habituation to nauseogenic motion when used in a novel accelerated training regime, 30 participants (13 men, 17 women, ages 18-51 years) were randomized to either a Breathing group or a Control group. Randomization was balanced for rotation tolerance measured during a first exposure to off-vertical axis rotation (OVAR 72 degrees sec.(-1)). Participants subsequently received four exposures to OVAR in 1-hr. (accelerated training). The Breathing group followed taped instructions to control their breathing during training and when retested the next day. There was overall habituation with stimulus repetition, shown by an increase in tolerance for motion, a reduction in symptoms, and speeded recovery times on retesting. There was a tendency for greater habituation with controlled breathing.     

Relation matters: relative depth order is stored in working memory for depth

Eternity and the Future: A Critique of the Plotinian Myth in Pannenberg’s Theology

For Pannenberg, the eschatological future is considered as the locus where the ultimate causation lies. Such an idea shapes Pannenberg’s doctrinal accounts of Christ and the Trinity in an idiosyncratic way. However, as this article will indicate, the idea is derived from the Plotinian myth that time can become a whole and so a vessel of divine infinity when it reaches the End. Dispensing with the faulty assumption but retaining the concept of the priority of the future, this article will argue that divine eternity as the totality can engage with history directly at any point of time, without a detour via the eschaton.     

新生儿重症监护室中放弃治疗的伦理问题

对于新生儿重症监护室中的一部分危重新生儿,虽然可以借助高新尖的医疗技术挽留他们的性命,但却不能避免其出现影响远期生存质量的后遗症。因此患儿家属和医务人员陷入了是否对这些危重新生儿实施放弃治疗的两难困境。对NICU中放弃治疗的对象、伦理学依据、伦理学意义以及如何实施放弃治疗的问题加以讨论,为NICU医务人员提供有益参考。     

Reorientation and landmark-guided search by young children: evidence for two systems

Disoriented 4-year-old children use a distinctive container to locate a hidden object, but do they reorient by this information? We addressed this question by testing children's search for objects in a circular room containing one distinctive and two identical containers. Children's search patterns provided evidence that the distinctive container served as a direct cue to a hidden object's location, but not as a directional signal guiding reorientation. The findings suggest that disoriented children's search behavior depends on two distinct processes: a modular reorientation process attuned to the geometry of the surface layout and an associative process linking landmarks to specific locations.     

亲子间心理状态术语、非心理状态术语使用与儿童心理理论的关系

本研究通过观察亲子互动游戏来考查母亲———孩子间心理状态术语、非心理状态术语使用与儿童心理理论发展的关系。实验结果表明,控制了年龄因素后,儿童心理理论发展和母亲心理状态术语使用存在显著相关,提示母亲有效地谈论心理状态对儿童心理理论的发展具有影响;儿童心理理论发展与其心理状态术语使用也存在显著相关,提示儿童将心理理论任务中涉及的表征问题与信念词所隐含的表征属性相联系是形成心理理论、正确使用心理状态术语的前提。当控制了母亲和儿童的心理状态术语使用总数后,母亲及孩子非心理状态术语的使用与儿童心理理论发展都不再存在显著相关,提示非心理状态术语的使用是以心理状态术语使用为中介而对儿童的心理理论发展产生影响。
