The Job Demands-Resources Model and Job Burnout: The Mediating Role of Personal Resources

The primary purpose of this study is to test whether the effect of workload on emotional exhaustion (health impairment process) and social support on depersonalization (motivation process) could be mediated by personal resources such as self-efficacy, self-esteem and optimism. Two multiple mediation models are tested separately, and then the point estimate and bias-corrected and accelerated 95 % confidence interval of the total and specific indirect effect are determined using the bootstrap approach with 1000 bootstrapped samples. The results show that workload positively affects emotional exhaustion, whereas social support negatively affects depersonalization, thus further corroborating the health impairment process and motivation process as assumed by the job demands-resources (JD-R) model. The total indirect effect is significant for both models, and self-esteem and optimism are the significant mediators for the health impairment process, whereas only optimism is the significant mediator for the motivation process.     

Task-related functional connectivity of the caudate mediates the association between trait mindfulness and implicit learning in older adults

Accumulating evidence shows a positive relationship between mindfulness and explicit cognitive functioning, i.e., that which occurs with conscious intent and awareness. However, recent evidence suggests that there may be a negative relationship between mindfulness and implicit types of learning, or those that occur without conscious awareness or intent. Here we examined the neural mechanisms underlying the recently reported negative relationship between dispositional mindfulness and implicit probabilistic sequence learning in both younger and older adults. We tested the hypothesis that the relationship is mediated by communication, or functional connectivity, of brain regions once traditionally considered to be central to dissociable learning systems: the caudate, medial temporal lobe (MTL), and prefrontal cortex (PFC). We first replicated the negative relationship between mindfulness and implicit learning in a sample of healthy older adults (60–90 years old) who completed three event-related runs of an implicit sequence learning task. Then, using a seed-based connectivity approach, we identified task-related connectivity associated with individual differences in both learning and mindfulness. The main finding was that caudate-MTL connectivity (bilaterally) was positively correlated with learning and negatively correlated with mindfulness. Further, the strength of task-related connectivity between these regions mediated the negative relationship between mindfulness and learning. This pattern of results was limited to the older adults. Thus, at least in healthy older adults, the functional communication between two interactive learning-relevant systems can account for the relationship between mindfulness and implicit probabilistic sequence learning.     

概念性内隐记忆和外显记忆中熟悉性的关系研究

该文运用任务分离法和Remember/Know程序,以汉词为材料,研究集中注意和重度分散注意条件下概念性内隐记忆和熟悉性提取的关系。结果表明:(1)概念性内隐记忆和线索回忆中的熟悉性在两种注意水平下差异均显著,它们随注意负荷的增加而提高;(2)类别范例测验中不存在错误记忆,而线索回忆中出现了错误记得和错误知道。     

学习不良儿童的元认知偏差：内部线索的影响

通过改变实验材料内部线索,旨在考察内部线索在学习不良儿童元认知偏差形成过程中的影响。实验1发现,学习不良儿童低关联字对的元认知偏差显著高于一般儿童,关联强度对学习判断的影响显著小于对测试成绩的影响;实验2发现,学习不良儿童反向方向字对的元认知偏差显著高于一般儿童,关联方向对学习判断的影响显著小于对测试成绩的影响。综合以上研究发现,相对一般儿童,学习不良儿童存在更大的元认知偏差,内部线索对学习判断和测试成绩的影响不一致模式适用于两组儿童。     

母亲依恋风格与孤独症谱系障碍儿童母子依恋:母亲教养方式的中介作用

早期依恋对孤独症谱系障碍（Autism Spectrum Disorders,简称ASD）儿童的心理健康、人际关系以及未来的社会融合有重要影响。本研究采用问卷调查法,对从北京、青岛、郑州、武汉、无锡和赤峰市等地28所融合幼儿园中筛选出来的210名ASD儿童及其母亲进行施测,考察母亲的依恋风格对ASD儿童母子依恋的影响,以及母亲教养方式在其中的中介作用。研究发现：（1）总体而言,ASD儿童与母亲之间的依恋关系总体状况良好;轻度ASD儿童的母子依恋水平显著高于中度、重度ASD儿童;（2）母亲依恋回避、依恋焦虑与ASD儿童母子依恋均呈显著负相关;母亲关爱、鼓励自主与ASD儿童母子依恋均呈显著正相关,母亲控制与ASD儿童母子依恋呈显著负相关;母亲依恋回避、依恋焦虑与母亲关爱均呈显著负相关,与母亲控制均呈显著正相关;（3）母亲关爱在母亲依恋回避与ASD儿童母子依恋之间起部分中介作用,母亲关爱、母亲控制在母亲依恋焦虑与ASD儿童母子依恋之间起完全中介作用。     

表面相似性对数量关系和相对大小关系理解的影响

研究采用数量关系匹配任务和相对大小关系匹配任务,通过高表面相似性、低表面相似性和交叉映射三种实验条件,探讨表面相似性对儿童和成人数量与相对大小关系理解的影响。研究一对37名4岁儿童进行三次每次间隔半年的追踪测查,结果表明4~5岁间儿童理解数量关系和相对大小关系的水平有显著提高;4岁儿童对数量关系的理解受到表面相似性的影响,4~5岁儿童对相对大小关系的理解受到表面相似性的影响。研究二探究44名成人数量和相对大小关系理解的特点,结果发现,成人完成两种关系匹配任务时也受到表面相似性的影响。

新生儿情绪性语音加工的正性偏向——来自事件相关电位的证据

准确解码语音中的情绪信息能让个体更好地适应社会环境, 此能力对新生儿和婴儿尤其重要, 因为人类刚出生时听觉系统远比视觉系统发育得完善。虽然已有研究表明5~7月龄的婴儿能分辨不同情绪种类的语音, 但目前对新生儿的研究还非常少。人类是否在出生时即具有分辨不同种类情绪性语音的能力?新生儿对情绪的加工是否存在正性或负性偏向?本文选用odd-ball范式考察高兴、恐惧、愤怒三种韵律性语音在1~6天龄新生儿大脑中诱发的事件相关电位。实验1直接对比三种情绪性条件, 发现新生儿大脑的额区(F3和F4电极点)可以区分情绪性语音的正负性, 正性(高兴)语音诱发的“失匹配反应”幅度明显大于负性(愤怒和恐惧)语音。实验2采用偏差和标准刺激反转的odd-ball范式, 证实了实验1的结果并非源于三种情绪语音物理属性的差异。本文的结果提示, 新生儿大脑可自动辨别正性与负性情绪语音, 但尚不能将愤怒和恐惧两种负性语音区分开来。更重要的是, 高兴语音比两种负性语音诱发了更大的失匹配反应, 这一结果首次从神经学层面(电生理指标)为新生儿情绪性语音加工的正性偏向提供了证据。
