Communal Behaviors and Psychological Adjustment of Family Caregivers and Persons With Spinal Cord Injury

OBJECTIVE: Examined the influence of mutual communal behaviors on the adjustment reported by persons with spinal cord injury (SCI) and their family caregivers. Previous research has found that persons who have a history of mutually communal behaviors in relationships may react differently to relationship changes after an acquired physical disability than dyads with few communal behaviors. METHOD: Family caregivers and persons with SCI were administered measures of mutual communal behaviors, depression, and life satisfaction. Structural equation modeling was used to test the relations among caregivers' communal behaviors and care recipients' communal behaviors, depression, and life satisfaction. RESULTS: Caregiver and care recipient reports of communal behaviors were not significantly correlated. Significant paths indicated that care recipients' communal behavior scores were positively associated with their life satisfaction, and care recipients' depression was inversely associated with their life satisfaction. Caregivers' communal behavior scores were unrelated to their self-reported adjustment. CONCLUSIONS: Caregiver-care recipient dyads may differ in their perceptions of communal behaviors in their relationships. Although care recipient reports of communal behavior may be related to their life satisfaction, communal behaviors may not serve a similar function among caregivers of persons with SCI.

云南省大学生自杀行为及相关因素分析

采用SCL-90、青少年生活事件量表、应对方式量表、社会支持评定量表和自编的外显行为量表对云南省3313名大学生进行了测查,并探讨了包括自杀意念及自杀企图在内的自杀行为状况及其影响因素。结果表明:(1)427(13.2%)名大学生有自杀意念,卡方检验显示女生人数显著多于男生;154(4.7%)名大学生有过自杀企图,男女生人数没有显著差异;(2)自杀意念和自杀企图在人口统计学变量上有显著差异:在自杀意念上,女生、独生子女、文科生、来自城市的学生和不完整家庭的学生、月支出少于100元的学生得分显著高于与之对应的大学生;而在自杀企图上,只有来自城市的学生和不完整家庭的学生、月支出少于100元的学生得分显著高于与之对应的大学生;(3)大学生自杀意念和自杀企图与心理症状、生活事件、情感中心应对呈显著的正相关,与问题中心应对、社会支持呈显著的负相关;(4)在结构模型中,社会支持在心理症状和自杀行为中起到显著的调节作用,情感中心应对在生活事件、社会支持、社会支持对心理症状的调节作用中起显著的中介作用,而问题中心应对在生活事件、社会支持、社会支持对事件的调节作用中起显著的中介作用。     

情绪变化的自动化加工：来自EMMN的启示

人脑如何自动化加工瞬息万变的情绪信息?研究者们在借鉴听觉通道的失匹配负波(mismatch negativity, MMN)研究的基础上, 进一步发展出了表情失匹配负波(expression mismatch negativity, EMMN), 以此作为视觉情绪信息前注意加工的重要指标。与以往的一般视觉线索的视觉失匹配负波(visual mismatch negativity, vMMN)有所区别, EMMN研究专注于人脑如何自动化加工瞬息万变的情绪信息。当前的研究主要探讨了不同类型的面部表情、不同性别、高低流体智力个体的EMMN差异, 以及自闭症、抑郁症、精神分裂症等异常个体EMMN的特点。此外, 从预测编码的角度阐释了EMMN的机制。今后的研究有必要聚焦EMMN在临床诊断和治疗中的应用, 考察不同情绪线索EMMN的特点, 并进一步揭示EMMN的神经机制。     

Synelfin Regulation during the Critical Period for Song Learning in Normal and Isolated Juvenile Zebra Finches

Male zebra finches (Taeniopygia guttata) learn to sing during a critical period in adolescence. We previously described a presynaptic protein, synelfin, whose mRNA is increased early in this critical period in a brain nucleus specifically implicated in song learning, lateral MAN (lMAN). In the current study, in situ hybridization was used to map this change in gene expression to the subregion of lMAN that projects to the robust nucleus of the archistriatum (RA), the principal motor output of the telencephalic circuit that controls song production. Using confocal immunofluorescence microscopy, we detected numerous puncta of synelfin immunoreactivity that apparently represent presynaptic terminals from lMAN in the RA of young males. Synelfin immunoreactivity in RA declined abruptly between 40 and 45 days of age, a time of major synaptic reorganization in RA. This change did not occur until about 10 days after the decline in synelfin mRNA in cell bodies within lMAN, indicating a relatively slow turnover of the protein in presynaptic terminals and suggesting that some of the functional changes that occur during the critical period may arise from regulatory decisions that were initiated a week or more earlier. Depriving birds of tutoring did not halt or delay the decline of synelfin mRNA in lMAN. This change in gene expression must not be a consequence of early song learning, but may reflect an innate or programmed step in song circuit development.     

情感预测中的聚焦错觉

聚焦错觉是个体在进行情感预测时,错误地估计了聚焦事件会对情绪造成影响的一种倾向.聚焦错觉是造成情感预测偏差的重要原因.其心理机制主要包括直觉预测和可得性模型.聚焦错觉的影响因素主要有预测事件的情感效价、性质,情境因素、个体习惯和文化差异等.其应对策略主要有去焦点化和情感平均.未来的研究应从聚焦错觉与忽视情绪适应的关系、聚焦错觉的产生根源以及聚焦错觉与其他聚焦效应的关系等方面来进一步探讨.     

守范?失范?——作为参照点的社会规范对决策行为的影响

作为参照点的社会规范指个体为实现群体目标保持活动一致性所建立起来的、视为决策与判断标准的规范。社会规范研究经历了从完全理性到有限理性的转变过程。其对决策行为影响的解释机制包括预期理论、后悔理论、"齐当别"抉择模型、程数说和三参照点理论等,能较好解释避税、见死不救与医患冲突等现象。今后研究注意结合社会认知角度,实现研究思想与范式的转变,侧重探索多重参照点、群体决策机制,丰富跨文化研究等,为转型期的守范与失范行为提供科学的解释。
