组织社会化研究的整合：交互作用视角

组织社会化是个体由组织的外部成员转化为具有参与性和效益性内部人员的适应过程。当前组织社会化研究零碎、分裂,缺少统一理论做指导,亟须进行有效的整合。在论述整合的必要性的基础上,重点分析符号互动与组织社会化的关系,并建立组织社会化的交互作用模型,最后指出了模型的验证、细化及重视中介和调节变量等问题     

团队多样性与组织支持对团队创造力的影响

采用实验法在专业异质性与群体断层两个水平上操纵团队多样性, 通过两个实验考察团队多样性与组织支持的交互作用对团队创造力的影响。研究结果表明：(1)在独创性维度上, 专业异质团队在工具支持条件下的独创性显著高于专业同质团队, 情感和物质支持条件下二者差异不显著。当团队出现群体断层时, 情感支持与工具支持具有同样的促进作用, 即在这两种组织支持下, 强断层团队的独创性显著高于弱断层团队; 物质支持条件下二者差异不显著。(2)在适宜性维度上, 组织支持的主效应显著, 两个实验一致地发现物质支持条件下的适宜性显著高于情感支持和工具支持。本研究从团队多样性与组织支持交互作用的角度考察不同复杂程度、不同组织目标的多样性团队所需要的组织支持条件, 对促进团队创造力具有一定的理论与实践价值。     

高功能孤独症幼儿空间工作记忆的组块加工缺陷

孤独症谱系障碍者存在空间工作记忆加工缺陷,其具体受损环节尚不明确。组块是一种有效的策略性信息编码方式,是空间工作记忆的关键环节。高度结构化的刺激容易形成高水平组块,因此,刺激结构化程度对记忆效果的影响能够反映个体的组块加工能力。研究采用Sternberg空间工作记忆任务、Corsi空间广度任务,加入刺激结构化因素,考察高功能孤独症幼儿是否存在组块加工缺陷,并探讨组块加工是否直接影响到空间工作记忆容量。实验1采用Sternberg空间工作记忆任务,结果表明,ASD幼儿存在明显的组块加工缺陷。在易于组块的高结构化条件下,健康幼儿的记忆成绩明显较高,而ASD幼儿在高、低结构化条件下的记忆成绩并无显著差异。实验2采用Corsi空间广度任务,结果显示,不论高、低结构化条件,ASD幼儿的空间工作记忆容量均显著低于健康幼儿。但ASD幼儿由于存在组块加工缺陷,在高、低结构化条件下的记忆成绩差异较健康幼儿小。因此,ASD幼儿的组块能力一定程度上影响了空间工作记忆容量。此外,记忆存储器的异常可能也是ASD幼儿空间工作记忆容量不足的重要原因。研究表明,ASD幼儿的空间组块缺陷主要由于弱中央统合的认知风格,他们缺乏自上而下的组块加工动机,难以主动对刺激形成高水平组块编码,从而影响记忆效果。     

物体受力分析正误样例组合的学习效果

分别采用正误样例组合、有无错误标记的正误样例组合和有标记的正误样例配对组合设计方法,以物体受力分析正误样例为实验材料,以初中三年级学生为被试进行3项实验,考察了被试物体受力分析图正误样例组合的学习效果。结果表明,正误样例组合的学习成绩显著优于正确样例组合的学习成绩;有标记的正误样例组合的学习成绩显著优于无标记样例组合的学习成绩;有标记正误样例配对组合的学习成绩明显优于正确样例组合的学习成绩。     

教师情绪智力和工作绩效的关系：工作家庭促进和主动行为的中介作用

采用整群抽样法对630名中小学教师进行调查,考察教师情绪智力与工作绩效之间的关系,以及工作家庭促进和主动行为在其中的中介作用。结果发现：（1）教师情绪智力、工作促进家庭、家庭促进工作和主动行为与工作绩效呈显著正相关;（2）教师情绪智力对工作绩效具有直接的正向预测作用,同时还通过家庭促进工作和主动行为的多重中介作用对工作绩效产生影响;（3）高低情绪智力对工作绩效的影响机制不同,低情绪智力通过家庭促进工作的部分中介作用影响教师工作绩效,高情绪智力通过家庭促进工作和主动行为的完全多重中介作用影响教师工作绩效;（4）工作家庭促进中工作促进家庭维度在教师情绪智力影响工作绩效中没有显著中介作用。     

图-图干扰范式中语义效应的眼动研究*

采用眼动方法,在图-图干扰范式中探讨了干扰图的频率和语义类型对语义判断的影响。结果发现:(1)语义一致性的主效应显著,与目标图语义一致的干扰图获得的注视时间长于与目标图语义不一致的干扰图,证实了语义干扰效应的存在,与Dell的交互激活模型相吻合。(2)干扰图命名的词汇频率主效应不显著,未发现显著的频率效应,对词汇选择竞争假设提出质疑。     

科技干扰与青少年智能手机成瘾的关系：情绪症状和环境敏感性的作用

本研究以问卷法对湖北省两所中学共3219名初一至初三的中学生进行调查,建立结构方程模型来考察在家庭环境中由于父母使用科技设备而产生的科技干扰对青少年智能手机成瘾的影响机制。结果发现：（1）科技干扰不仅能直接正向预测青少年智能手机成瘾,还能通过情绪症状的中介作用间接预测青少年智能手机成瘾;（2）环境敏感性在情绪症状对青少年智能手机成瘾的影响中起显著的调节作用,具体而言,较高的环境敏感性能够缓冲情绪症状对青少年智能手机成瘾的影响。     

Association of Dopamine D2 Receptor Gene with Creative Ideation

Although several studies suggest that dopamine D2 receptor (DRD2) gene may contribute to creativity, the relationship between DRD2 and creativity still needs to be further validated. To further test the relevance of DRD2 and creativity, this study explored the association between DRD2 and creative ideation in 483 unrelated healthy Chinese undergraduate students. A total of 15 single nucleotide polymorphisms (SNPs) covering the DRD2 were genotyped, and creative ideation was assessed by the Runco Ideational Behavior Scale (RIBS). Single SNP analysis showed that 2 SNPs (rs4648317 and rs4938019) were nominally associated with fluency, 4 SNPs (rs4648317, rs4938019, rs4648319, and rs1800497) were nominally associated with flexibility, and 1 SNP (rs4648317) was nominally associated with originality. Haplotype analysis showed several haplotypes were nominally associated with various creative ideation indexes. However, none of these nominal associations survived correction for multiple testing. Overall, this study provides suggestive evidence for the genetic impact of DRD2 on creative ideation and supports the assumption that the genotype variations in DRD2 contribute to creativity.     

When a Dog Has a Pen for a Tail: the Time Course of Creative Object Processing

Creative objects differ from ordinary objects in that they are created by human beings to contain novel, creative information. Previous research has demonstrated that ordinary object processing involves both a perceptual process for analyzing different features of the visual input and a higher-order process for evaluating the relevance of this visual information. However, it is unclear how and when these processes are influenced by the creative information of the object. This study utilized event-related potentials (ERPs) to investigate the time course of creative object processing. Behavioral results revealed that participants spent more time processing creative objects than they did ordinary objects. Analysis of scalp ERPs further revealed that creative objects elicited a more negative ERP deflection between 190 and 340 ms (N190–340) with an anterior scalp distribution. Additionally, creative objects elicited more positive ERP deflection than did ordinary objects between 400 and 700 ms (P400–700) with a right centro–parietal scalp distribution and between 700 and 1000 ms (late positive component) with a right anterior–central scalp distribution. Such results suggest that the processing of creative objects is composed of two distinct stages. The early perceptual stage involves the detection of visual differences exhibited by the creative objects, while the late stage involves the right-lateralized processes of understanding and encoding the creative information.     

The temporal dynamics of detached versus positive reappraisal: An ERP study

Detached reappraisal and positive reappraisal are regarded as two distinct types of cognitive reappraisal strategy, and the former is considered more disengaging than the latter. The conceptual framework of emotion regulation choice posits that strategies involving disengagement operate earlier and more efficiently than engagement strategies. Here, we compare for the first time the temporal dynamics of detached and positive reappraisal during the regulation and re-exposure phases thereof by measuring event-related potentials. During the regulation phase, pictures were viewed or regulated using detached or positive reappraisal. During the re-exposure phase, the same pictures were viewed again. Results showed that during regulation, central-parietal late positive potentials (LPPs) were greatly attenuated under both strategy types, with the regulation effect of detached reappraisal occurring earlier than that of positive reappraisal and resulting in a stronger attenuation of LPP amplitudes. Upon re-exposure, detached reappraisal exerted enduring effects on self-reported arousal and the central-parietal LPP, whereas positive reappraisal had an enduring effect only on pleasantness. These findings demonstrate the differential effects of detached and positive reappraisal on valence, arousal, and neural responses, and underline the striking differences in the temporal dynamics of these reappraisal strategies.
