创伤个体注意控制、焦虑及情绪对闯入记忆的影响

以往研究认为认知控制在闯入记忆的发展中起一定作用。研究以83名大学生本科生为被试,采用创伤电影范式和问卷调查结合的方式,旨在考察创伤个体注意控制、焦虑及情绪对闯入记忆的影响。结果显示,注意控制、焦虑和情绪与闯入记忆相关;注意控制和观看创伤电影前的消极情绪对闯入记忆有一定的预测作用;注意控制与焦虑、情绪相关;高低注意控制组分别在焦虑、情绪上差异显著。注意控制、焦虑、创伤前负性情绪与闯入记忆相关;注意控制、创伤前负性情绪显著影响闯入记忆。 关键词：闯入记忆;注意控制;焦虑;情绪;创伤     

工作不安全感对员工心理与行为的影响

采用工作不安全感问卷,对不同企业的223名员工进行调查,探讨了工作不安全感中各维度对员工心理与行为的具体影响。结果表明:(1)在工作执行和人际关系不安全感上,男女性别差异显著;在工作丧失、人际关系不安全感、群体组织公民行为以及留职意愿这四个维度上,不同企业类型差异显著。(2)工作丧失、工作执行,人际关系不安全感均对留职意愿有正向预测作用;过度竞争不安全感对群体组织公民行为及个体组织公民行为均有显著的负向预测作用。     

先秦推类方法的模式构造及有效性问题

援类而推的方法,是中国先秦时代特有的并广泛使用的一种思维方法。对于这种推类方法,古代先贤只给出了一系列的语义说明,没有而且也不可能给出一个形式语言的语形说明。如借助现象对事物的状态和功能及其所具有的规律进行描述的科学认识方法,我们今天可以尝试着给它构造一个推理模式,并通过分析它的思维进程、根据、推导原则及违反原则的错误,展现它的特点、能够成立的有效性及世代相传的普遍适用性。并进而了解其背后的逻辑原则、文化传统、人文精神,从逻辑与文化的角度增强我们对传统思维方法论意义、文化认同意义的感受。并在全球化的浪潮中,在越来越广泛的文化交流与沟通中,促进对传统思维方式的辩证扬弃,促进不同文化之间思维方式的沟通。     

奖励影响注意选择的认知加工机制

奖励不仅能够塑造行为, 也能影响个体的内部心理过程。在注意选择过程中, 与奖励联结的刺激能够吸引注意资源。当目标刺激与奖励联结时, 能够易化注意选择过程; 当分心刺激与奖励联结时, 能够阻碍注意选择过程。可见, 奖励从不同角度对注意选择产生影响。奖励对注意选择的影响可能有其特有的认知机制, 并且奖励对注意的捕获效应受到许多因素的调节, 如奖励预测、工作记忆容量、人格特质及刺激的新异性。未来的研究应该尝试将奖励影响注意选择的研究成果应用于不良注意偏向临床干预的实践领域。     

Selflessness as a universal neuropsychological foundation of spiritual transcendence: validation with Christian,Hindu, and Muslim traditions

Research with US and European Christians has shown that increased spiritual transcendence is related to decreased right hemisphere/right parietal lobe (RH/RPL) functioning, which has been inferred as relating to increased “selflessness”. To determine if RH/RPL selflessness is a universal neuropsychological foundation for spiritual transcendence across cultures and religions, this study evaluated 109 individuals with traumatic brain injury from the US and India, including Christians, Hindus, and Muslims. Participants completed measures of spiritual transcendence and spatial perception as an index of the functional integrity of the RH/RPL. Spearman correlations indicated that decreased RH/RPL functioning is significantly associated with increased spiritual transcendence for the entire sample, but not for different cultures or religions, likely due to decreased statistical power. The results suggest that decreased RH/RPL-related selflessness is a universal neuropsychological foundation for spiritual transcendence across cultures and faith traditions, which is interpreted individually based on cultural and religious background (e.g., closeness to God, Allah, and Brahman).     

我国农民工核心心理健康素质的调查

旨在考察《中国成年人核心心理健康素质总量表》在农民工群体中的心理测量学特征,了解我国农民工心理健康素质的基本情况,并与全国成年人常模进行比较。采用《中国成年人核心心理健康素质总量表》,对来自于全国六大区域的不同性别、年龄段、教育程度和职业类别的855名农民工有效样本进行问卷调查。结果发现:(1)本次调查中《中国成年人核心心理健康素质总量表》各分量表的信效度符合心理测量学要求;(2)农民工样本核心心理健康素质量表总均分处于中等偏上水平;(3)农民工的情绪性素质得分高于全国成年人常模,其他素质和核心心理健康素质总量表得分与全国常模无显著差异;(4)农民工坚韧性素质得分存在显著性别差异,人际健康和情绪性素质得分存在显著年龄差异,自我概念、坚韧性素质和核心心理健康素质总量表得分存在显著的职业差异。结论:《中国成年人核心心理健康素质总量表》适用于农民工群体;农民工情绪性素质优于全国常模,其他所测心理健康素质的负载量与全国常模处于同一水平。     

Effects of a ‘Learn to Think’ intervention programme on primary school students

Background. Methods for teaching thinking may be described as out‐of‐context or infusion. Both approaches have potential to raise students’ general cognitive processing ability and so raise academic achievement, but each has disadvantages. Aims. To describe and evaluate a theory‐based learn to think (LTT) curriculum for primary school students, which draws on the strengths of both out‐of‐context and infusion approaches. Sample. One‐hundred and sixty‐six students in three classes of Grade 1 (6+ years old), Grade 2 (7+ years old), and Grade 3 (8+ years old) in a primary school in Shanxi province, China, randomly ascribed to experimental (90) and control (76) groups. Methods. All students were pre‐tested for non‐verbal intelligence and academic achievement. Experimental students followed the LTT curriculum (one activity every 2 weeks) for 4 school years. All were post‐tested on three occasions for thinking ability and four times for academic achievement. Results. Grade 1 and Grade 2 students showed effects of LTT from 1 year after their start and increasing: on thinking ability d= .78–1.45; on Chinese d= .68–1.07; on maths .58–.87. Grade 3 students showed effects from 6 months after their start: on thinking ability .90–1.37; Chinese .77–1.32; maths .65–1.29. The effects were concentrated in students in the middle band of initial ability. Conclusions. A curriculum for teaching thinking based on a structured theoretical model that combines elements of out‐of‐context and infusion methods has been shown to have long‐term far transfer effects on students’ thinking ability and academic achievement. More work is needed to meet the needs of a wider range of abilities.     

The effects of autonomy and empowerment on employee turnover: test of a multilevel model in teams

Extending research on voluntary turnover in the team setting, this study adopts a multilevel self-determination theoretical approach to examine the unique roles of individual and social-contextual motivational precursors, autonomy orientation and autonomy support, in reducing team member voluntary turnover. Analysis of multilevel time-lagged data collected from 817 employees on 115 teams indicates that psychological empowerment mediates the main effect of autonomy orientation and the interactive effect of autonomy support and its differentiation on a team member's voluntary turnover. The findings have meaningful implications for the turnover and self-determination literatures as well as for managers who endeavor to prevent voluntary turnover in teams.     

Effects of Phonetic Similarity in the Identification of Mandarin Tones

Tonal languages differ in how they use phonetic correlates e.g. average pitch height and pitch direction, for tonal contrasts. Thus, native speakers of a tonal language may need to adjust their attention to familiar or unfamiliar phonetic cues when perceiving non-native tones. On the other hand, speakers of a non-tonal language may need to develop sensitivity to tonal correlates absent from their native system. The current study examines and compares five language groups’ perception of two synthesized Mandarin tones: the high level tone and the high falling tone. It aims to examine how listeners from tonal and non-tonal backgrounds identify and categorize acoustically equidistant pitches varying along two phonetic dimensions: pitch onset and slope. Results reveal “universal” perceptual patterns across groups and also tendencies caused by native tonal systems. Our findings confirm that L1 tonal and prosodic systems affect speakers’ sensitivity to novel perceptual cues and their abilities to discern relevant phonetic differences.     

无关长时记忆表征能否引导视觉注意选择?

与任务相关的长时记忆表征在引导视觉注意选择的过程中扮演着重要的角色,它可以使人们在熟悉的视觉情境中快速搜索目标刺激,并偏离干扰刺激。但当长时记忆表征与任务无关时,还能否引导视觉注意选择?目前还不清楚。实验1采用眼动追踪技术直接比较无关工作记忆表征与无关长时记忆表征在视觉搜索阶段对视觉注意的捕获效应,行为反应时与首次注视点百分率的结果都发现,当无关工作记忆表征在视觉搜索中再次出现时能引导视觉注意偏向到与之匹配的干扰刺激,但无关长时记忆表征并没有表现出类似的注意引导效应;实验2探讨记忆表征由工作记忆系统转移到长时记忆系统的过程中对视觉注意的引导效应,结果发现,随着记忆表征的转移,注意引导效应消失了,实验3排除工作记忆表征的干扰后,依然没有发现无关长时记忆表征对注意的引导效应。以上结果表明,无关长时记忆表征并不能像工作记忆表征一样引导视觉注意选择,工作记忆表征和长时记忆表征对视觉注意的引导属于两个不同的认知过程。
