自然自明性的失落——Blankenburg精神分裂理论述评

传统的精神分裂研究,关注的主要是精神分裂的妄想症候群。因为精神分裂中相对特殊的症状,在妄想形式中可以得到最轻易的把握。Blankenburg则认为:精神分裂的本质结构变异是先于妄想的。因此,他致力于在精神分裂的症状贫乏型(主要是青春型和单纯型)中,寻找精神分裂的本质变异。他发现:精神分裂异常中的核心缺损是自然自明性的失落。根据胡塞尔的超越现象学,自然自明性失落有四个原因:与世界关系的改变、时间建构的改变、自我建构的改变、交互主体性的改变。Blankenburg的精神分裂理论,作为二十世纪有关精神分裂的最重要工作之一,对于今天的精神分裂研究仍然有极其重要的意义。     

Muscular Activation Pattern of Bilateral Extensors Response to Asymmetric Hand Lifting During Trunk Flexion–extension Performance

The authors' purpose was to test the effect of asymmetric hand lifting on muscular activation patterns of 3 bilateral extensors. Eighteen male university students without back pain were volunteered. Each performed flexion–extension randomly with conditions of right lifting, left lifting, and nonlifting. Surface electromyography from bilateral thoracic, lumbar erector spinae, and hamstring was recorded. The cross-correlation and relative intensity in paired muscles of bilateral extensors was calculated in flexion as well as extension period. The results showed that the cross-correlation coefficient was decreased and the phase lag as well as the relative intensity of bilateral extensors was increased significantly in thoracic level. The phase lag as well as the relative intensity of bilateral extensors was increased significantly in lumbar level. It was concluded that asymmetric lifting has a significant effect on muscular activation of bilateral extensors in thorax level, which causes the ipsilateral extensor to activate larger and longer. Asymmetric lifting also has some effect on muscular activation of bilateral extensors in lumbar level but with less extent than in thorax level, which causes contralateral extensor to activate larger and longer. Asymmetric lifting seems to have no significant effect on muscular activation of bilateral hamstring.     

组织支持感对组织认同的影响:内部人身份感知和自尊的中介作用

检验了内部人身份感知(PIS)和基于组织的自尊(OBSE)在组织支持感(POS)对组织认同的影响过程中的角色和地位。采用多样本结构方程建模的方法,通过对中国2家企业的员工的问卷调查所获取的452份有效数据进行分析,结果表明:(1)POS对PIS和OBSE有直接的显著影响;(2)同时借助于PIS和OBSE的中介作用对组织认同产生间接的影响。     

记忆暗示感受性的双加工机制研究

该研究使用延迟的提取错误范式和R/K/G范式相结合的方法,从编码、误导和提取这三个加工阶段中重要影响因素对记忆暗示感受性产生的交互效应出发,深入考查了记忆暗示感受性产生过程中动态的自动加工与控制加工成分贡献。结果发现:(1)相比无意加工,编码阶段的有意加工更有利于记忆暗示感受性的产生。(2)当个体在编码阶段进行有意加工时,时间压力干扰能发挥其效应,明显提高了其记忆暗示感受性。(3)浅加工编码、时间压力条件下的记忆暗示感受性包含更多的自动加工成分;深加工编码条件下的记忆暗示感受性包含更多的控制加工成分。     

本科生导师指导对新生大学适应性的影响:自我效能感的中介作用

基于社会支持理论和社会认知理论,构建以自我效能感为中介变量的理论模型,通过对523名本科生新生问卷调查,检验本科生导师指导影响新生大学适应性的内在机制。回归分析结果显示,导师指导各维度对大学适应性均有显著正向作用;自我效能感在导师指导和大学适应性之间起完全中介作用。这提示高校管理者在具体实施中应该进一步细化和规范新生导师制,并关注学生自我效能感的激发。     

Engagement Attentional Bias toward Value-Associated Stimuli

Recent evidence has shown that learning to associate the value of behavioral outcomes with specific stimuli (i.e., value learning/association) can induce attentional capture in a subsequent visual search task. Here we investigated the component of attentional bias toward value-associated stimuli in the dot-probe paradigm. In the training phase, participants learned to associate nonsense shape outlines with monetary wins or losses. The shapes were then used as cues in an explicit no feedback dot-probe task. Probe appeared at either the salient (congruent trial) or nonsalient location (incongruent trial). Results indicate attentional bias toward value-associated stimuli, futher more this attentional bias is driven by an engagement bias.     

Are Individuals with Schizophrenia or Schizotypy More Creative? Evidence from Multiple Tests of Creative Potential

Schizophrenia and schizotypy have been often associated with above average creativity; however, empirical studies on the relationship between schizophrenia spectrum disorders and enhanced creativity generated inconsistent results. This research investigates if the association between schizophrenia spectrum disorders and creative potential levels is dependent upon which cognitive processes are examined during administered tests of creative potential. Our study examined 117 participants stratified into the following three subgroups: (a) 39 psychometrically determined low-schizotypal individuals, (b) 35 psychometrically determined high-schizotypal individuals, and (c) 43 patients with schizophrenia. Each participant completed 2 divergent thinking (DT) tasks, 2 convergent thinking (CT) tasks, and 2 creative tasks that combine both DT and CT processes. The data suggest that Group C had typical abilities in the DT, CT, and the combined creative thinking tasks; however, the group as a whole had intact originality during the Figural Completion (DT task) and the Tangram Construction (combined task). Notably, Group B showed significant advantages in both verbal and figural DT tasks. Group A and Group B demonstrated no significant differences in the creative thinking processes of CT; however, both groups outperformed Group C in these tasks.     

情绪概念加工与情绪面孔知觉的相互影响

通过3个实验探讨情绪概念加工与情绪面孔知觉是否存在相互影响, 以及加工深度对两者关系的影响。实验1采用情绪面孔启动范式, 探讨较深的情绪概念加工层面对情绪概念与情绪面孔的关系的影响。实验2更改概念任务, 探讨较浅的概念加工层面对两者关系的影响。实验3缩短启动面孔呈现时间, 探讨较浅的面孔知觉层面对两者关系的影响。通过研究主要得出以下结论：(1)情绪概念加工与情绪面孔知觉确实存在相互影响; (2)概念加工深度影响两者关系的方向性, 在较深的概念加工层面, 两者的关系是双向的, 在较浅的概念加工层面, 两者的关系是单向的; (3)知觉加工深度也影响两者关系的方向性, 在较深的知觉加工层面, 两者的关系是双向的, 在较浅的知觉加工层面, 没有发现两者的相互影响。本研究为抽象概念的具身表征提供了实证支持。     

中学生社会支持对数学学习坚持性的影响:数学自我效能感的中介作用

以北京市通州区一所普通中学的228名初一和初二学生为被试,采用领悟社会支持量表、数学自我效能感和数学学习坚持性问卷,考察在中学生数学学习中不同来源的社会支持对数学学习坚持性的影响,并检验数学自我效能感在其中的中介作用。结果发现:(1)社会支持中的教师支持和同伴支持能够显著正向预测数学学习坚持性水平,而父母支持的预测作用不显著;(2)数学自我效能感在同伴支持和数学学习坚持性之间起完全中介作用,在教师支持和数学学习坚持性之间起部分中介作用。     

不同依恋风格者情绪调节策略的认知神经特点

情绪调节是依恋研究的重要方面。本文依托Gross的情绪调节理论和相关认知神经证据,阐述了三种依恋风格者的情绪调节特点。焦虑型依恋调节负性情绪时存在注意分配的优势和表达抑制的不足;调节正性情绪时还采用了情景选择和情景修正策略。回避型依恋调节两种效价情绪均使用了表达抑制,调节正性情绪时还使用了认知重评。安全型依恋使用认知重评、注意分配和情景修正策略,效价差异不突出。探讨依恋与情绪调节的关系,有利于改善非安全型依恋的情绪调节能力。
