创造性思维与认知抑制的关系

抑制是创造性思维过程中的一种重要的认知加工机制。创造性思维与认知抑制的关系主要有三种观点：创造性思维的认知去抑制假说、认知抑制假说和适应性认知抑制假说。本文系统评述了创造性思维与认知抑制关系的相关理论、研究新进展和神经机制。未来研究应加强创造性思维与认知抑制关系的理论整合与构建,分析创造性思维的不同阶段的认知抑制机制,采用无意抑制与有意抑制研究范式,对创造性思维与认知抑制的关系、影响因素及神经机制进行深入研究。     

Social Media and Language Processing: How Facebook and Twitter Provide the Best Frequency Estimates for Studying Word Recognition

Corpus‐based word frequencies are one of the most important predictors in language processing tasks. Frequencies based on conversational corpora (such as movie subtitles) are shown to better capture the variance in lexical decision tasks compared to traditional corpora. In this study, we show that frequencies computed from social media are currently the best frequency‐based estimators of lexical decision reaction times (up to 3.6% increase in explained variance). The results are robust (observed for Twitter‐ and Facebook‐based frequencies on American English and British English datasets) and are still substantial when we control for corpus size.     

The Effects of Zhongyong Thinking Priming on Creative Problem‐Solving

Zhongyong thinking is a common approach adopted by Chinese people to solve problems encountered in life and work. Based on the four modes of zhongyong thinking proposed by Pang (Social Sciences in China, 1, 1980, 75), this study chooses the “neither A nor B” form, which represents the “mean” (中) characteristics of zhongyong thinking, called eclectic thinking, and the “both A and B” form, which reflects the “harmony” (和) feature, called integrated thinking. This study primed eclectic thinking and integrated thinking, respectively, through self‐compiled problem situations, and 150 college students and postgraduates students were the participants. Experiment 1 explored the role of the priming of zhongyong thinking in three classic creative thinking tasks: a divergent thinking test, remote association test, and insight problem‐solving test. Experiment 2 further examined the effect of priming of zhongyong thinking on “market investment problems” with higher ecological validity. The findings show that priming integrated thinking can improve remote associates test performance and promote creative solutions to market investment problems, but there is no significant impact on the scores of divergent thinking test and insight problem‐solving; priming eclectic thinking has no significant impact on any of the subsequent creative tasks. This study shows that integrated thinking primes cognitive processing related to information association and information integration, promoting subsequent creative tasks.     

创造性认知风格、创造性人格与创造性思维的关系

对315名初中生施测Kirton适应–创新认知风格问卷、Williams创造性倾向量表和Torrance创造性思维测验任务,以考察创造性认知风格、创造性人格与创造性思维之间的关系。相关分析表明,在创造性认知风格中,效率性、规则性均与创造性思维呈显著负相关;在创造性人格中,冒险性、好奇心及挑战性均与创造性思维显著正相关。回归分析进一步表明,在创造性认知风格中,创新性、效率性分别正向、负向预测创造性思维,在创造性人格中,好奇心正向预测创造性思维;对回归系数的逐步检验发现,创新性维度通过创造性人格而对创造性思维具有间接的积极影响。结构方程模型结果则显示,创新性维度、规则性维度以创造性人格为中介分别对创造性思维发生间接的积极、消极影响。可见,创新认知风格有利于创造性思维,而适应认知风格不利于创造性思维;创造性人格有利于创造性思维;创造性人格在创造性认知风格与创造性思维之间具有一定的中介作用,创新性认知风格通过创造性人格而促进创造性思维,规则性认知风格通过创造性人格而抑制创造性思维。     

Incremental Bayesian Category Learning From Natural Language

Models of category learning have been extensively studied in cognitive science and primarily tested on perceptual abstractions or artificial stimuli. In this paper, we focus on categories acquired from natural language stimuli, that is, words (e.g., chair is a member of the furniture category). We present a Bayesian model that, unlike previous work, learns both categories and their features in a single process. We model category induction as two interrelated subproblems: (a) the acquisition of features that discriminate among categories, and (b) the grouping of concepts into categories based on those features. Our model learns categories incrementally using particle filters, a sequential Monte Carlo method commonly used for approximate probabilistic inference that sequentially integrates newly observed data and can be viewed as a plausible mechanism for human learning. Experimental results show that our incremental learner obtains meaningful categories which yield a closer fit to behavioral data compared to related models while at the same time acquiring features which characterize the learned categories. (An earlier version of this work was published in Frermann and Lapata 2014 .)     

WINDSOR: Windsor improved norms of distance and similarity of representations of semantics

Lexical co-occurrence models of semantic memory form representations of the meaning of a word on the basis of the number of times that pairs of words occur near one another in a large body of text. These models offer a distinct advantage over models that require the collection of a large number of judgments from human subjects, since the construction of the representations can be completely automated. Unfortunately, word frequency, a well-known predictor of reaction time in several cognitive tasks, has a strong effect on the co-occurrence counts in a corpus. Two words with high frequency are more likely to occur together purely by chance than are two words that occur very infrequently. In this article, we examine a modification of a successful method for constructing semantic representations from lexical co-occurrence. We show that our new method eliminates the influence of frequency, while still capturing the semantic characteristics of words.     

The cognitive underpinnings of creative thought: A latent variable analysis exploring the roles of intelligence and working memory in three creative thinking processes

The field of creativity has largely focused on individual differences in divergent thinking abilities. Recently, contemporary creativity researchers have shown that intelligence and executive functions play an important role in divergent thought, opening new lines of research to examine how higher-order cognitive mechanisms may uniquely contribute to creative thinking. The present study extends previous research on the intelligence and divergent thinking link by systematically examining the relationships among intelligence, working memory, and three fundamental creative processes: associative fluency, divergent thinking, and convergent thinking. Two hundred and sixty five participants were recruited to complete a battery of tasks that assessed a range of elementary to higher-order cognitive processes related to intelligence and creativity. Results provide evidence for an associative basis in two distinct creative processes: divergent thinking and convergent thinking. Findings also supported recent work suggesting that intelligence significantly influences creative thinking. Finally, working memory played a significant role in creative thinking processes. Recasting creativity as a construct consisting of distinct higher-order cognitive processes has important implications for future approaches to studying creativity within an individual differences framework.     

A Cross‐Cultural Study of Task Specificity in Creativity

This study provides new evidence concerning task specificity in creativity—examining through a cross‐cultural perspective the extent to which performance in graphic versus verbal creativity tasks (domain specificity) and in divergent versus convergent creativity tasks (process specificity) are correlated. The relations between different creativity tasks in monocultural and multicultural samples of Chinese and French children were compared. Electronic versions of the Wallach and Kogan Creativity Test (WKCT , W allach & K ogan, 1965; L au & C heung, 2010) and the Evaluation of Potential Creativity (EP oC; L ubart, B esançon, & B arbot, 2011; B arbot, B esançon, & L ubart, 2011) were used. Both measures showed satisfactory psychometric properties and cross‐cultural structural validity. The results showed that culture has an impact on the structure of creative ability: It appeared that correlation patterns were different across Chinese and French groups and across monocultural and multicultural groups. Such results show that it is crucial to take task specificity into account when investigating the effect of culture on creativity. Indeed, our study implies that cultural differences that are found using one specific creativity task might not be automatically generalizable to all sorts of creativity tasks. Limitations are discussed and perspectives for future research on culture and task specificity in creativity are proposed.     

Constructive controversy and creative process engagement: The roles of positive conflict value,cognitive flexibility,and psychological safety

This research explores how and when constructive controversy enhances creative process engagement. We identify positive conflict value and cognitive flexibility as two mediating processes that transmit the effect of constructive controversy on creative process engagement. We further theorize that psychological safety shows opposing moderating effects: It strengthens the positive conflict value–creative process engagement link, whereas weakens the cognitive flexibility–creative process engagement link. Moreover, we propose that psychological safety strengthens and weakens the two mediating pathways through positive conflict value and cognitive flexibility, respectively. Results based on a multiwave data involving 239 employees from the research and development division of a large high‐technology company provide support for our hypotheses. Theoretical and practical implications are discussed.

Creative Thinking: Processes,Strategies, and Knowledge

Creative achievements are the basis for progress in our world. Although creative achievement is influenced by many variables, the basis for creativity is held to lie in the generation of high‐quality, original, and elegant solutions to complex, novel, ill‐defined problems. In the present effort, we examine the cognitive capacities that make creative problem‐solving possible. We argue that creative problem‐solving depends on the effective execution of a set of complex cognitive processes. Effective execution of these processes is, in turn, held to depend on the strategies employed in process execution and the knowledge being used in problem‐solving. The implications of these observations for improving creative thinking are discussed.     

Linkographic Evidence for Concurrent Divergent and Convergent Thinking in Creative Design

For a long time, the creativity literature has stressed the role of divergent thinking in creative endeavor. More recently, it has been recognized that convergent thinking also has a role in creativity, and the design literature, which sees design as a creative activity a priori, has largely adopted this view: Divergent and convergent thinking are seen as occurring in cyclic phases within the design process. Neurological evidence suggests that frequent shifts between defocused and focused attention to stimuli in memory activation, which equate divergent and convergent thinking, are a hallmark of creative thinking. In this article, we use linkography to show that the shifts between divergent thinking—forelinking of design moves, and convergent thinking—backlinking of moves, are so frequent that at the cognitive scale they can be seen as occurring concurrently in the ideation phase of creative designing. It is proposed that in assessments of creative potential, shifts between divergent and convergent thinking should be the yardstick instead of, or alongside measurements of divergent thinking.     

艺术设计中创造性思维的fMRI研究：一项基于智能CAD的探索

本项工作尝试将人类思维的神经生物学基础研究与人工智能的研究成果相结合, 利用类比生成模型的原理, 开发了一个计算机辅助设计系统“多源类比人脸生成系统”, 并运用此平台开展了fMRI实验, 对人类大脑创造性思维的神经生物学机制进行了探索。实验采用open-ends模式下的“design task”和problem solving模式下的“control task”作为对照, 共采得15名健康成人被试的有效数据。数据结果显示design task与control task相比更为显著地激活了内侧前额叶、额中回、右侧颞上回、前扣带回、双侧海马、楔前叶这些脑区。综合以往研究推测, 内侧前额叶可能更多地与即兴自由创作中对自我信息的表征有关, 颞叶可能与不断产生和输出新颖性的观点有关, 边缘系统则可能主要与创造性活动中的动力驱动作用有关。总的来说, 创造性思维是多个脑区同时参与的高度分布式加工的结果。     

创造性思维的脑机制

创造性思维是创造性的核心。近年来,脑电和脑成像技术的发展为研究创造性思维的神经基础提供了有力的技术支持,对创造性思维的脑机制研究取得了较大进展。创造性思维的脑机制研究主要包括顿悟的脑机制、发散性思维的脑机制、远距离联想的脑机制、言语创造性和图画创造性的对比的脑机制研究。研究结果显示创造性思维需要多个脑区的参与,因不同的认知任务其关键脑区而有所不同。对创造性思维的脑机制研究进行了总结,对这些研究可能存在创造性思维究竟应该定义为“领域一般的”还是“领域特殊的”的解释进行了讨论,并指出了研究中可能存在的基线任务设置问题和未来研究中需要在研究手段、研究设计、研究领域等方面加以改进的建议     

语言转换影响双语认知优势的发展进程

本研究包括两部分,第一部分对双语转换问卷进行修订,用于客观测量双语者的语言转换能力;第二部分采用数字命名任务考察语言转换对双语认知优势发展进程的影响。结果发现,在低水平阶段,语言转换频率与转换消耗存在显著负相关;在高水平阶段,语言转换频率与转换消耗、混用消耗均存在显著负相关。结果说明,语言转换首先影响瞬时转换能力,积累一定的经验之后,才会对持续监控能力与抑制控制能力产生积极影响。本研究结果表明,双语认知优势效应的发展具有一定的顺序性。     

思维与语言的关系：来自认知神经科学的证据

在有关人类心智的研究中,思维与语言的关系始终是一个复杂而重要的课题。借助于新的技术手段和研究思路,当代认知神经科学从新的角度探讨了这个古老而神秘的课题。其研究的基本逻辑是：如果某种特定的思维过程（比如简单的算术运算或者三段论推理）在本质上是“语言的”,那么,在进行这种思维活动时,大脑中负责语言信息处理的区域就会参与;反之,如果某种思维过程在本质上是“空间的”,则大脑中负责空间信息处理的区域就会参与其中。结合来自直观的脑功能图谱证据与其它的跨领域证据（如来自行为实验和脑损伤研究的证据）,能够帮助我们更加深入地认识和理解思维与语言的关系问题。     

Personality variables and problem‐construction activities: An exploratory investigation

Problem‐construction and problem‐finding activities have been shown to have a marked impact on creative achievement. Although cognitive operations play an important role in problem construction, there is reason to suspect that personality variables might influence effective process application. In the present study we constructed measures of personality characteristics that might influence adaption to novel, ill‐defined tasks. These measures were administered to 250 undergraduates who were also asked to complete a problem‐construction task. A series of discriminant analyses indicated that personality variables could be used to identify individuals who generated high‐quality, original problems. The implications of our findings for understanding exactly how personality variables interact with cognitive operations in the problem‐construction process are discussed.     

Are Speedy Brains Needed when Divergent Thinking is Speeded—or Unspeeded?

In this study, we focus on mental speed and divergent thinking, examining their relationship and the influence of task speededness. Participants (N = 109) completed a set of processing speed tasks and a test battery measuring divergent thinking. We used two speeded divergent-thinking tasks of 2 minutes and two unspeeded tasks of 8 minutes to test the influence of task speededness on creative quality and their relation to mental speed. Before each task, participants were instructed to be creative in order to optimally measure creative quality. We found a large main effect of task speededness: less creative ideas were generated when tasks were speeded as compared to unspeeded (Cohen's d = −1.64). We could also replicate a positive relationship of mental speed with speeded divergent thinking (r = .21) and mental speed with unspeeded divergent thinking (r = .25). Our hypothesis that the relation is higher for the speeded divergent-thinking tasks was not confirmed. Importantly, variation in creative quality scores under speeded conditions was not explained by mental speed beyond the predictive power of unspeeded creative quality. The latter finding implies that measurement of creative quality under speeded conditions is not confounded by mental speed.     

高低创造性思维水平者定向遗忘效应的差异研究

采用单字法定向遗忘范式,考察远距离联想任务得分高低者在中性和负性词语定向遗忘效应上的差异,来探讨创造性思维水平高低与主动抑制的关系。实验采用2(高/低创造性思维水平)×2(中性/负性词汇)×2(记住/忘记指令)×2(2s/5s时间间隔)混合设计,发现高低创造力组,在材料不同呈现时间下,对不同情绪材料的定向遗忘效应分别不同。低创者在2s和5s以及高创者在5s时间间隔时,均对中性词语表现出定向遗忘效应,而对负性词汇没有表现出明显的定性遗忘效应。高创者在2s时间间隔下,对中性和负性词语均表现出定向遗忘效应。结果表明较短时间内高创者对负性情绪的主动抑制能力优于低创者。
