科学创造力与艺术创造力:启动效应及领域影响

如何有效地提升创造力,是创造力研究和实践领域的核心问题之一.而对创造力表达及其影响机制的把握则是创造力提升的必要前提.本研究计划通过实施科学创造力及艺术创造力的启动实验,以不同专业大学生为被试,来探索科学创造力和艺术创造力表达的个体心理机制,及外部影响的作用模式,从而厘清在动机启动、样例启动和自我启动之间,究竟何种启动模式对创造力的表达最为有效;进而,通过对来自理工科和艺术专业领域评分者对科学创造力及艺术创造力作品的评分比较,来考查两种创造力模式间可能存在的领域影响.经由以上的探究,试图为科学与艺术创造力的发展与促进提供科学依据和建构理论框架.     

认知抑制对科学创造力和艺术创造力的影响

研究通过2个实验,考察不同高低抑制水平对科学创造力和艺术创造力的影响。通过安排不同难度的Simon任务（不一致试次占70%或10%）来消耗被试的认知资源,达到操纵被试的抑制水平,以侧抑制任务的前后测来评估被试抑制水平的变化情况,实验1和实验2分别以科学创造力测验和粘贴画任务测量被试的科学创造力和艺术创造力。结果发现,在科学创造力测验上,高抑制水平组被试的流畅性和灵活性得分显著高于低抑制水平组;在粘贴画任务中,低抑制水平组被试的创造性、可爱程度、综合印象得分以及总分均显著高于高抑制水平组。表明高认知抑制水平有利于科学创造力,低认知抑制水平有利于艺术创造力,认知抑制对科学创造力和艺术创造力的影响存在分离效应。     

创造力有其“阴暗面”

创造力有其“阴暗面”。从产品角度而言,创造力可产出伤害性或消极的产品;从个体角度而言,高创造力者可能具有一些消极特征,如精神疾病易感性强、宜人性差、说谎、不诚信等;从情境角度而言,高创造力表现可能与不信任感、生存危机感、社会拒绝等消极因素有关。未来研究应开发高生态效度的恶意创造力测评工具,改进计算恶意创造力水平的算法,探索消极个体特征和消极情境因素作用于创造性思维的认知与神经机制。     

青少年科学创造力的理论研究与实践探索

系统梳理了20年来青少年科学创造力的理论研究与实践探索,包括概念与结构、测量与发展、影响因素和机制、培养思路与模式等,分析了科学创造力研究的趋势,提出了若干重要的研究方向。在未来的研究中,要加强几个方面的研究工作,即科学创造力的认知神经机制研究,科学创造力的基因组学研究,基于情境和内容的科学创造力研究,教学活动或项目促进科学创造力发展的神经可塑性机制研究,以及基于聚合科技的科学创造力培养。     

不同科学创造力个体干扰抑制机制的比较*

选取《科学创造力量表》筛选出高、低科学创造力个体各20名,通过完成经典Stroop色字干扰抑制任务,探讨高、低科学创造力的个体抑制机制的差异。结果发现:在Stroop色字任务上,无论是高科学创造力组还是低科学创造力组,都出现了Stroop干扰效应,但低科学创造力组的Stroop效应更明显;高科学创造力组在字色不一致条件下的错误率显著低于低科学创造力组,但是两组被试在Stroop任务反应时上差异不显著。本研究结果提示高科学创造力个体的认知抑制能力强于低科学创造力个体。     

情绪调节中的认知重评创造力

情绪调节能力是维护个体心理健康和生活幸福的基本能力。认知重评创造力是个体面对负性情境时能够自发产生多种认知重评策略的能力, 是情绪调节任务中的创造性行为。研究表明, 认知重评创造力与发散性思维和开放性正相关, 与神经质、特质愤怒无关; 创造性的认知重评策略或运用隐喻和类比的高水平认知重构更有利于负性情绪的调节; 创造性的认知重评可以通过基于杏仁核的显著情绪唤醒, 基于海马的新联想形成和基于纹状体的精神奖赏的中介来调节情绪, 从而产生可以保存在长时记忆中的新颖的、积极的情绪体验。上述结果支持认知重评的创造性重构理论。认知重评创造过程需要自上而下的认知控制和情绪表征的特定执行功能。未来研究可以扩大被试群体, 完善认知重评创造力的测量方法, 探索影响认知重评创造力的情境因素和内在因素, 以及进一步揭示认知重评创造力区别于传统创造力的特别加工或反应机制的神经机制。     

认知抑制对艺术创造力的影响:认知风格的调节作用

以114名大学生为被试, 采用Mittenecker指向测验和粘贴画任务考察了认知抑制能力与艺术创造力的关系, 并采用镶嵌图形测验考察了认知风格在其中所起的调节作用。研究结果表明:(1)认知抑制能力与艺术创造力之间呈现负相关, 认知抑制对于个体的创造程度、沟通传播水平和艺术创造综合印象可以起到显著的负向预测作用, 对于个体艺术创造的可爱程度和想象水平可以起到边缘显著的负向预测作用;(2)认知风格在认知抑制能力与艺术创造力的关系中起着调节作用, 主要表现为认知抑制能力对于场依存个体的创造程度、想象水平和沟通传播水平具有显著的预测作用, 对于场独立个体的艺术创造力则不具有预测作用。     

有关创造力测量的一些思考

创造力测量是创造力研究的基础, 然而该领域研究成果却一直饱受质疑, 因此如何准确测量创造力是研究者亟需解决的问题。近几年, 创造力测量领域围绕一些研究热点, 在多方面取得显著进展。例如：发散思维测验独特性维度的计分问题, 或许可以通过主观计分法解决; 顿悟类测验可能表征个体创造力水平, 但效度仍有待于进一步确认; 创造力成就测验可能带来的共同方法变异问题, 需要通过合理应用测验规避; 同感评估技术或许会引起评定者效应; 研究者开始从语义网络角度测量创造力等等。未来该领域研究应当在：基本概念问题上达成共识; 从测验内容和施测过程优化测验质量; 采用混合测验的策略以及通过跨领域研究增进测量技术多样化等方面进行努力。     

创造力产生过程中的神经振荡机制

创造力究竟是怎么产生的, 目前尚未得出一致的结论。神经电生理技术因其高时间分辨率, 可以准确地揭示创造力产生进程中的神经振荡机制, 从而帮助人们更深刻地理解创造力的本质。近年来的研究发现, 单节律alpha神经振荡会随着创造力的增加而增强, 这反映了创造力产生过程中的内部信息加工需求增加、自上而下的抑制控制增强。同时, 多频段神经振荡交叉节律耦合体现了创造性产生过程中额叶、颞叶和顶叶等多脑区之间信息交流的动态变化。未来研究应该以整合理论框架为基础, 结合多层次多方法的研究工具, 引进更生态化的数理计算方法, 并利用计算神经科学建模来预测个体创造力发展趋势, 从而全面深刻地认识创造力的本质。     

家长式领导对多层面创造力的作用机制

作为一种具有中国文化特色的领导模式, 家长式领导对多层面的创造力均有显著影响。基于对以往实证研究的分析, 文章针对家长式领导及其维度与多层面创造力之间的直接关系、交互效应、调节效应与作用机制等问题进行了梳理与阐述, 构建了“家长式领导影响员工及团队创造力的作用机制”模型; 进而指出, 家长式领导对员工创造力的作用受到工作情境、个体因素的调节效应并有赖于个体心理认知和社会关系的中介作用, 它还以团队认知和团队互动为中介作用于团队创造力。未来研究应努力拓展研究层次, 丰富研究方法, 并从跨文化视角系统探索家长式领导对多层面创造力的作用机制。     

The Effects of Extrinsic Motivation on Scientific and Artistic Creativity among Middle School Students

The present study tested the effects of extrinsic motivation on scientific and artistic creativity among Chinese middle school students. In Study 1, a between-groups design was applied to examine the effects of expected rewards on scientific and artistic creativity among 123 students, and in Study 2 the same design was applied to examine the effects of expected evaluation from different raters on scientific and artistic creativity among 120 students. We also considered the effects of grade and gender in both studies. The results of Study 1 indicated that expected material reward had significant negative effects on scientific creativity for 7th graders, while expected social reward had significant positive effects on scientific creativity for 8th graders, and both expected material and social rewards had significant positive effects on artistic creativity. The results of Study 2 indicated that expected evaluation from teachers and classmates had significant negative effects on scientific creativity and significant positive effects on artistic creativity. These results suggest that there is no one-size-fits-all answer to the effects of extrinsic motivation and creativity, Factors such as culture, type of extrinsic motivation, grade, and domains of creativity must be fully considered when cultivating adolescents’ creativity.     

青少年创造性发展及其脑机制研究进展

青少年时期是创造性发展的关键阶段,探明青少年创造性发展规律及其神经机制对于培养和激发个体的创新潜能具有重要意义。本文综述了青少年创造性发展及其脑机制的研究进展,分别对青少年创造性思维发展趋势、影响因素及其相应的脑机制展开综述,并在此基础上进行了展望。总体而言,青少年时期创造性思维发展呈现出两个波峰(11~13岁,15~16岁)的发展趋势;青少年创造性发展受外部原生家庭教养方式和学校教师激励以及内部情绪动机和自我管理能力的影响较大;前额叶对青少年创造性发展具有重要作用,这可能与该脑区涉及执行控制功能有关。针对青少年创造性发展的教育干预以及大脑可塑性可能成为该领域的研究热点;而大样本纵向跟踪多模态脑影像数据库的建立可为相关研究提供重要支持。     

Different roles of shared and vertical leadership in promoting team creativity: Cultivating and synthesizing team members’ individual creativity

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed.     

The Octopus Approach in Time Management: Polychronicity and Creativity

The current study examined the associations among polychronicity, creativity and perceived time pressure in a military context. Polychronicity refers to an individual’s preference for working on many tasks simultaneously as opposed to 1 at a time. As hypothesized, polychronicity was negatively related to creativity. In addition, perceived time pressure moderated this relationship. Specifically, polychronic individuals exhibited less creativity when their perceived time pressure was high. The results underscore that, although today’s work environment encourages polychronic approach, it, when reinforced with perceived high time pressure, runs the risk of reducing creativity, which is a critical driver for the survival of organizations.     

The Importance of the Default Mode Network in Creativity—A Structural MRI Study

Anecdotal reports as well as behavioral studies have suggested that creative performance benefits from unconscious processes. So far, however, little is known about how creative ideas arise from the brain. In the current study, we aimed to investigate the neural correlates of creativity by means of structural MRI research. Given that unconscious and less controlled processes are important in creative thinking, structural brain research may find a positive correlation between well‐established creativity measures and cortical thickness in brain structures of the default mode network (i.e., the counterpart of the cognitive control network). Individuals performed the Alternative Uses task by which an individual's cognitive flexibility and the average uniqueness and average creativity of a participant's ideas were assessed. We computed optimized voxel‐based‐morphometry (VBM) to explore the correlation between inter‐individual differences in creativity and inter‐individual differences in gray matter volume. For all creativity measures, a positive correlation was found between creative performance and gray matter volume of the default mode network. These findings support the idea that the default mode network is important in creativity, and provide neurostructural support for the idea that unconscious forms of information processing are important in creativity. Theoretical and practical implications are discussed.     

多巴胺相关基因甲基化、家庭环境与创造力的关系

“遗传与环境”的争论一直是创造力研究的核心问题, 但目前对于环境以及遗传与环境交互作用对创造力影响的分子生物机制还未有研究涉及。近年来, 随着表观遗传学的兴起, 揭示影响心理行为的表观遗传机制现已成为心理学研究的热点。作为环境与基因组之间的纽带, 表观遗传学研究为揭示环境以及遗传与环境交互作用对创造力影响的分子生物机制提供了机遇。本研究以多巴胺相关基因、家庭环境以及两者对于创造力的交互作用为切入点, 对影响创造力的表观遗传机制进行考察, 并在此基础之上, 对环境以及遗传与环境交互作用对创造力影响的分子生物机制进行探索。具体研究内容包括：(1)通过对多巴胺相关基因甲基化模式与创造力关系的系统考察, 筛选出甲基化模式与创造力有关的基因; (2)对筛选出的基因, 进一步考察其甲基化模式在家庭环境及其遗传多态性与家庭环境交互作用对创造力影响中的中介作用。本研究有助于揭示创造力的表观遗传机制, 深化关于遗传与环境对创造力影响的作用机制的理解。
