发散性思维与幽默的认知神经机制比较——基于双加工理论的视角

在双加工理论视角下对发散性思维与幽默的认知神经机制进行了系统整理。发现二者的认知加工过程具有相似性：前期都依赖于自动化加工;而后期随着认知负荷的增加,越来越依赖控制化加工。脑机制方面：控制化加工条件下,二者的神经机制重叠部分比自动化加工条件下多,其中负责控制化加工的前额皮层是二者共同的关键脑区。未来可从两类加工协同合作的角度深入揭示发散性思维与幽默的内在机制。     

认知控制在发散性思维中的作用

探讨认知控制在发散性思维中的作用是当前创造力研究领域的热点问题。目前一致认为认知控制包括工作记忆、抑制控制和认知灵活性三个核心成分。工作记忆对个体在发散性思维中维持任务目标、提取和操作信息发挥重要作用; 抑制控制, 包括优势反应抑制、分心干扰抑制和对潜在相关信息的低抑制, 分别压制对常规观点的提取、确保对内在注意状态的维持和提供更多观念的组合, 进而促进个体的发散性思维表现。此外, 流体智力作为一种高级认知控制能力, 可通过增强策略使用的灵活性从而利于发散性思维。近来神经科学研究表明, 发散性思维不同阶段需要执行控制网络和默认网络的动态协同加工。未来研究应澄清认知控制各子成分间的关系, 探讨认知控制影响发散性思维是否受到其他因素(如动机和情绪)的调节, 以及探索执行控制网络和默认网络的动态协作是否受到任务要求和个体差异(如人格和智力)的影响。     

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.     

Cognitive Abilities Involved in Insight Problem Solving: An Individual Differences Model

This study investigated individual differences in cognitive abilities that contribute to solving insight problems. A model is proposed describing three types of cognitive ability that contribute independently to insight: convergent thinking, divergent thinking, and breaking frame. The model was tested in a large sample (N = 108) by regressing insight problem solving performance on measures of these three abilities. This analysis demonstrated that all three abilities predicted insight independently. Convergent thinking was further broken down into verbal intelligence and working memory, which also predicted insight independently of each other and of divergent thinking and breaking frame. Finally, when pitted against noninsight problem solving as a predictor in regression, only insight problem solving was uniquely associated with divergent thinking and breaking frame. The model is suggested as a potentially useful taxonomy for the study of ill-defined problems and cognitive abilities.     

Openness to Experience and Intellect Differentially Predict Creative Achievement in the Arts and Sciences

The Big Five personality dimension Openness/Intellect is the trait most closely associated with creativity and creative achievement. Little is known, however, regarding the discriminant validity of its two aspects—Openness to Experience (reflecting cognitive engagement with perception, fantasy, aesthetics, and emotions) and Intellect (reflecting cognitive engagement with abstract and semantic information, primarily through reasoning)—in relation to creativity. In four demographically diverse samples totaling 1,035 participants, we investigated the independent predictive validity of Openness and Intellect by assessing the relations among cognitive ability, divergent thinking, personality, and creative achievement across the arts and sciences. We confirmed the hypothesis that whereas Openness predicts creative achievement in the arts, Intellect predicts creative achievement in the sciences. Inclusion of performance measures of general cognitive ability and divergent thinking indicated that the relation of Intellect to scientific creativity may be due at least in part to these abilities. Lastly, we found that Extraversion additionally predicted creative achievement in the arts, independently of Openness. Results are discussed in the context of dual‐process theory.     

EFFECTS OF FEEDBACK AND COGNITIVE PLAYFULNESS ON PERFORMANCE IN MICROCOMPUTER SOFTWARE TRAINING

A field experiment of 68 full-time employees studied the effects of performance feedback and cognitive playfulness (that is, cognitive spontaneity in human-computer interactions) on microcomputer training performance. In addition, this research examined the impacts of performance feedback and cognitive playfulness on software efficacy perceptions and on a variety of affective outcomes, including satisfaction with feedback, satisfaction with training, and positive mood. The findings suggest that positive feedback generally results in higher test performance and more positive affective outcomes, than does negative feedback. Similarly, employees higher in cognitive playfulness demonstrated higher test performance and more positive affective outcomes than those lower in cognitive playfulness. Finally, a significant feedback × playfulness interaction on test performance was found. Specifically, employees lower in cognitive playfulness benefited more from the positive feedback than did those higher in cognitive playfulness. Implications for practice and future research are discussed.     

A New Neurocognitive Model for Assessing Divergent Thinking: Applicability,Evidence of Reliability,and Implications for Educational Theory and Practice

A new model is presented to assess divergent thinking from a neurocognitive perspective. Evidence is presented showing its sensitivity to capture differences in divergent thinking. This observational interview-based study used a two-dimensional matrix (grid) composed of dimensions derived from neuropsychology and cognitive science theory. Each category (grid cell) is related to a particular cognitive operation that putatively is mediated by one or more functional/anatomical brain regions. Using the coding matrix, data were obtained from 30 middle school students through interviews and think-aloud responses to questions. Students were videotaped while viewing rich pictorial material and responses were coded and characterized for divergent production using 10 coefficients: higher category responses, detail, spontaneous generation, perspective switching, category switching per probe, category switches per utterance, different switches, detail per switching ratio, new subjects, higher category responses and reasoning. Reliability was obtained by interobserver concordance and Cohen's kappa coefficients were calculated for the cognitive and brain functional references dimensions (.90 and .91, respectively). Individual differences were expressed as variations in divergent thinking, providing a convenient way of assessing divergent thinking that may be related to creative thinking in education. This model may have heuristic value beyond research on creativity by providing a theoretical framework to guide further research on the cognitive correlates of divergent thinking with brain functional modules by correlating brain imaging data with concurrent interview data gathered by use of the model.     

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.     

不同冥想类型对创造性思维的影响及作用机制

冥想与创造性的关系正逐渐被关注,澄清冥想练习对创造性思维的影响效果和作用机制对个体创新潜能的培养与提升具有重要意义。不同冥想类型对创造性思维的影响具有特异性,专注冥想主要通过注意聚焦和提升自上而下的执行控制能力来对聚合思维产生积极影响;正念冥想引起的离焦的注意状态,以及对认知灵活性和积极情绪的促进,有助于发散思维。未来应加强不同冥想类型与创造性思维的整合研究,探讨冥想影响创造性思维的脑机制,以及冥想与其他干预训练对创造性思维的不同作用机制等。     

Influence of divergent and convergent thinking on visuomotor adaptation in young and older adults

Visuomotor adaptation declines in older age. This has been attributed to cognitive impairments. One relevant cognitive function could be creativity, since creativity is implicated as mediator of early learning. The present study therefore evaluates whether two aspects of creativity, divergent and convergent thinking, are differentially involved in the age-dependent decline of visuomotor adaptation.In 25 young and 24 older volunteers, divergent thinking was assessed by the alternative-uses-task (AUT), convergent thinking by the Intelligenz-Struktur-Test-2000 (IST), and sensorimotor-adaptation by a pointing task with 60° rotated visual feedback.Young participants outperformed older participants in all three tasks. AUT scores were positively associated with young but not older participants’ adaptive performance, whereas IST scores were negatively associated with older but not young participants’ adaptive performance. This pattern of findings could be attributed to a consistent relationship between AUT, IST and adaptation; taking this into account, adaptation deficits of older participants were no longer significant.We conclude that divergent thinking supports workaround-strategies during adaptation, but doesn’t influence visuomotor recalibration. Furthermore, the decay of divergent thinking in older adults may explain most of age-related decline of adaptive strategies. When the age-related decay of divergent thinking coincides with well-preserved convergent thinking, adaptation suffers most.     

Divergent thinking is not a general trait: A multidomain training experiment

Twenty‐one second‐grade subjects received divergent‐thinking training and 20 matched subjects received training in solving mathematical word problems. All subjects were then given five tasks: telling stories, writing stories, writing poems, writing mathematical word problems, and making collages. Experts evaluated the creativity of each product. The divergent‐thinking groups scored significantly higher than controls on the story‐telling, story‐writing, and poetry‐writing tasks. The lack of correlations among scores on the five tasks, however, suggests that several task‐specific factors, rather than one general factor, led to observed group differences. This is consistent with previous research using subjects untrained in divergent thinking in showing that divergent thinking is not a general trait.     

Investigating the interaction between schizotypy, divergent thinking and cannabis use

Cannabis acutely increases schizotypy and chronic use is associated with elevated rates of psychosis. Creative individuals have higher levels of schizotypy, however links between cannabis use, schizotypy and creativity have not been investigated. We investigated the effects of cannabis smoked naturalistically on schizotypy and divergent thinking, a measure of creativity. One hundred and sixty cannabis users were tested on 1 day when sober and another day when intoxicated with cannabis. State and trait measures of both schizotypy and creativity were administered. Quartile splits compared those lowest (n=47) and highest (n=43) in trait creativity. Cannabis increased verbal fluency in low creatives to the same level as that of high creatives. Cannabis increased state psychosis-like symptoms in both groups and the high creativity group were significantly higher in trait schizotypy, but this does not appear to be linked to the verbal fluency change. Acute cannabis use increases divergent thinking as indexed by verbal fluency in low creatives.     

The Influence of Creativity on Incongruity-Resolution and Nonsense Humor Comprehension

Both creativity and humor are high-level cognitive functions and complex concepts. Although creativity and humor are generally deemed positively correlated, it has been difficult to explicitly identify their relationship with each other. The cognitive process of creativity includes divergent thinking, insight, and remote association, whereas humor comprehension includes incongruity resolution and nonsense humor. The difference between the 2 types of humor is in whether individuals can understand the content of jokes through logical deduction. This study explored the relationship of the different dimensions of cognitive creativity and incongruity-resolution and nonsense humor comprehension. Furthermore, we examined the influence of divergent thinking, insight, and remote association on incongruity-resolution and nonsense humor comprehension. The scores from 103 participants on a divergent thinking questionnaire, an insight problem-solving task, and the Chinese compound remote associate problems test were used to analyze their comprehension of incongruity resolution and nonsense humor. The results showed a positive correlation between remote association and incongruity-resolution humor comprehension, as well as a positive correlation between insight and nonsense humor comprehension. These findings indicate that each dimension of cognitive creativity has a particular way of connecting to various types of humor comprehension.     

A meta-analytic investigation of the relationship of state and trait anxiety to performance on figural and verbal creative tasks

Extensive research suggests when and how anxiety has debilitating or facilitating effects on routine cognitive tasks or motor tasks. However, research examining anxiety's relation to performance on creative tasks such as divergent thinking and artistic tasks is less conclusive despite a rather substantial literature. The authors' meta-analytic investigation of 59 independent samples finds that anxiety is significantly and negatively related to creative performance. In addition, the findings provide insights into factors such as task complexity, type of task (i.e., figural or verbal), and type of anxiety (i.e., state or trait) that moderate the relationship between anxiety and creativity-all of which are consistent with the idea that anxiety and creativity present competing cognitive demands. In addition to identifying gaps in the literature such as the need for research using a two-component model of anxiety in relation to creativity, the authors' results have practical implications for those seeking to increase individual creativity.     

禅修对创造性思维的影响

禅修是一种能够对人类心理有广泛影响的训练工具。作为两种重要、相似但又不同的禅修方式, 冥想和正念对创造性思维中的发散思维和聚合思维产生了不同影响。在发散思维方面, 冥想主要通过对注意调控和无意识激活影响以及对解题动机和情绪的有效调控两方面显著增强了发散思维, 尤其是认知灵活性; 在聚合思维方面, 正念和冥想的影响相当复杂, 主要是通过聚合思维所需的执行功能和可能涉及表征重构来促进定势转移或功能固着的消除。就机制而言, 禅修对创造性思维的影响总体上不仅得益于走神时的无意识关联加工, 而且受禅修中诱发的情绪效应的调节。基于这些, 对未来研究的趋势进行了展望。     

An investigation into the relationships between convergent and divergent thinking, schizotypy, and autistic traits

This study explored the relationships between positive and negative schizotypy, convergent and divergent thinking, and autistic traits within the normal population. Seventy-seven students at Oxford University completed tasks to assess divergent and convergent thinking, and completed questionnaires to measure schizotypy and autistic tendencies. Evidence for relationships between negative schizotypy, autistic traits, and convergent thinking was found, but the expected association between positive schizotypy and divergent thinking was not replicated. These findings are discussed in the context of a cognitive inhibition theory of creativity.     

模糊容忍性与发散性思维的关系：不同认识兴趣的作用

Mental abilities and school achievement: A test of a mediation hypothesis

This study analyzes the interplay of four cognitive abilities - reasoning, divergent thinking, mental speed, and short-term memory - and their impact on academic achievement in school in a sample of adolescents in grades seven to 10 (N = 1135). Based on information processing approaches to intelligence, we tested a mediation hypothesis, which states that the complex cognitive abilities of reasoning and divergent thinking mediate the influence of the basic cognitive abilities of mental speed and short-term memory on achievement. We administered a comprehensive test battery and analyzed the data through structural equation modeling while controlling for the cluster structure of the data. Our findings support the notion that mental speed and short-term memory, as ability factors reflecting basic cognitive processes, exert an indirect influence on academic achievement by affecting reasoning and divergent thinking (total indirect effects: β = .22 and .24, respectively). Short-term memory also directly affects achievement (β = .22).     

Preference for Complexity and Asymmetry Contributes to Elaboration in Divergent Thinking

The study continues the exploration of the contribution of creative perception to creative potential. Creative potential was operationalized as divergent thinking and measured by the Abbreviated Torrance Test for Adults. Creative perception was operationalized as a preference for complexity and asymmetry and was assessed by a standard Barron-Welsh Art Scale. Sixty-five undergraduate college students participated in the study. Preference for complexity and asymmetry was found to make a measurable contribution to the elaboration trait of divergent thinking. This finding suggests that in addition to the process, product, person, place, persuasion, and potential perspectives, creativity construct can be evaluated from the standpoint of creative perception.     

The Measurement and Prediction of Managerial Creativity

The relations between creative management performance and constructs from the cognitive ability and personality domains were explored. A new openness scale and measures of divergent thinking and general intelligence were correlated with independently obtained criterion assessments of creative-management performance for 221 managers from a variety of organizations. Divergent thinking and openness correlated significantly with key creative-management criteria. General intelligence correlated only marginally with the criteria, and when divergent thinking was statistically removed, not at all. Divergent thinking, conversely, retained its significant criterion correlations with general intelligence statistically removed. Finally, a predictive composite of both divergent thinking and openness is shown to provide solid prediction of managerial creativity and significant utility in a personnel selection context.
