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。     

Working memory benefits creative insight, musical improvisation, and original ideation through maintained task-focused attention

Anecdotes from creative eminences suggest that executive control plays an important role in creativity, but scientific evidence is sparse. Invoking the Dual Pathway to Creativity Model, the authors hypothesize that working memory capacity (WMC) relates to creative performance because it enables persistent, focused, and systematic combining of elements and possibilities (persistence). Study 1 indeed showed that under cognitive load, participants performed worse on a creative insight task. Study 2 revealed positive associations between time-on-task and creativity among individuals high but not low in WMC, even after controlling for general intelligence. Study 3 revealed that across trials, semiprofessional cellists performed increasingly more creative improvisations when they had high rather than low WMC. Study 4 showed that WMC predicts original ideation because it allows persistent (rather than flexible) processing. The authors conclude that WMC benefits creativity because it enables the individual to maintain attention focused on the task and prevents undesirable mind wandering.     

The Impact of Affective States and Affective Shifts on Creative Ideation and Evaluation

This study aims to examine the impact of affective states and affective shifts on ideation and evaluation of creativity. Affects were induced by a two‐stage imagination procedure of recalling autobiographical experiences. Three periods of divergent thinking were measured to represent the participants’ creative ideation at different times. Creative evaluation was measured by estimating the originality of each response provided by the participants. The results indicate that (a) during the initial period of ideation, groups with positive affect obtain better creative ideation than the groups with neutral or negative affect. (b) The ideation in positive affect groups gradually decreases over time, while the ideation in negative affect groups gradually increases over time. (c) During the evaluation of originality, groups with negative affect have a higher proportion of over‐estimates and a lower proportion of under‐estimates than groups with positive affect. The viewpoints of cognitive tuning theory, which posit that the affective state influences creativity, are supported.     

Genes for Psychosis and Creativity: A Promoter Polymorphism of the Neuregulin 1 Gene Is Related to Creativity in People With High Intellectual Achievement

ABSTRACT— Why are genetic polymorphisms related to severe mental disorders retained in the gene pool of a population? A possible answer is that these genetic variations may have a positive impact on psychological functions. Here, I show that a biologically relevant polymorphism of the promoter region of the neuregulin 1 gene (SNP8NRG243177/rs6994992) is associated with creativity in people with high intellectual and academic performance. Intriguingly, the highest creative achievements and creative-thinking scores were found in people who carried the T/T genotype, which was previously shown to be related to psychosis risk and altered prefrontal activation.     

Development and Psychometric Integrity of a Measure of Ideational Behavior

Although creativity is an important part of cognitive, social, and emotional activity, high-quality creativity assessments are lacking. This article describes the rationale for and development of a measure of creative ideation. The scale is based on the belief that ideas can be treated as the products of original, divergent, and creative thinking-a claim J. P. Guilford (1967) made years ago. Guilford himself assessed ideation with tests of divergent thinking, although through the years scores from these tests have only moderate predictive validity. This may be because previous research has relied on inappropriate criteria. For this reason, the Runco Ideational Behavior Scale (RIBS) was developed. It can be used as a criterion of creative ideation. Most items describe actual behaviors (i.e., overt actions and activities) that clearly reflect an individual's use of, appreciation of, and skill with ideas. Results obtained using both exploratory and confirmatory factor analysis are reported in this article. These suggest the presence of 1 or 2 latent factors within the scale. Based on the theoretical underpinnings of the scale, a 1-factor solution was judged to be more interpretable than a 2-factor solution. Analyses also supported the discriminant validity of the RIBS.     

Creative production by angry people peaks early on, decreases over time, and is relatively unstructured

Anecdotes and introspective reports from eminent scientists and artists aside, a systematic test of the putative creativity-enhancing effect of anger is missing. This article fills this void with three experiments examining creativity as a function of anger (vs. sad or a mood-neutral control state). Combining insights from the literatures on creativity and on mood and information processing the authors predicted that anger (vs. sadness and a mood-neutral control state) triggers a less systematic and structured approach to the creativity task, and leads to initially higher levels of creativity (as manifested in original ideation and creative insights). Following work on resource depletion, the authors further predicted that anger more than sadness depletes resources and that, therefore, creative performance should decline over time more for angry than for sad people. Results supported predictions. Implications for creativity, information processing, and resource depletion are discussed.     

Creative ways to well-being: Reappraisal inventiveness in the context of anger-evoking situations

Neuroscientific studies in the field of creativity mainly focused on tasks drawing on basic verbal divergent thinking demands. This study took a step further by investigating brain mechanisms in response to other types of creative behavior, involving more “real-life” creativity demands in the context of emotion regulation and well-being. Specifically, functional patterns of EEG alpha activity were investigated while participants were required to generate as many and as different ways as possible to reappraise presented anger-eliciting situations in a manner that reduces their anger. Cognitive reappraisal involves some of the same cognitive processes as in conventional verbal creativity tasks, inasmuch as it requires an individual to inhibit or disengage from an emotional event, to shift attention between different perspectives, and to flexibly adopt new solutions. To examine whether alpha oscillations during cognitive reappraisal are different from those during conventional creative ideation, the EEG was also assessed during performance of the Alternative Uses task, requiring individuals to generate as many and as original uses of an object as possible. While cognitive reappraisal was associated with a similar pattern of alpha power as observed in conventional verbal creative ideation, the former yielded significantly stronger alpha power increases at prefrontal sites, along with lower alpha increases at more posterior cortical sites, indicating higher cognitive control and less spontaneous imaginative thought processes in the generation of effective strategies to regulate an ongoing negative emotional state.     

The Mediating Role of Creative Process Engagement in the Relationship between Shyness and Self‐Rated Creativity

Shyness has been found to have a negative impact on creativity. However, little attention has been given to the underlying process of the relationship between shyness and creativity. On the basis of literature, we hypothesize that shyness has an indirect impact on creativity through creative process engagement. Two studies were conducted on undergraduate students (Study 1) and working adults (Study 2) to test the hypothetical relationship. Analysis on participants self‐report showed that shyness was negatively associated with self‐reported creativity as well as creative process engagement. There was a positive relationship between creative process engagement and creativity. More importantly, mediation analysis supported that shyness was indirectly linked to creativity via creative process engagement. Specifically, shy people are found to be less involved in creativity‐relevant processes such as information searching and idea generation. The low level of creative process engagement, in turn, hinders their creativity. The findings not only lend support to the detrimental effect of shyness on creativity but also shed light on the underlying mechanism of the relationship.     

Creativity and schizotypy from the neuroscience perspective

Behavioral research has revealed that some cognitive features may be similar between creative and psychotic/schizophrenic-like thoughts. In this study, we addressed the potential link between creativity and schizotypy at the level of the brain by investigating functional patterns of brain activity (using functional magnetic resonance imaging) during creative cognition in preselected groups with low versus high psychometrically determined schizotypy. Our findings revealed an association between the originality component of creativity and reduced deactivation of right parietal brain regions and the precuneus during creative cognition, congruent with the idea that more-creative people may include many more events/stimuli in their mental processes than do less-creative people. Similarly, the high-schizotypy group showed weaker deactivation of the right precuneus during creative cognition. The fact that originality and schizotypy show similar functional brain activity patterns during creative ideation (i.e., reduced deactivation of the right precuneus) strongly supports the contention that similar mental processes may be implicated in creativity and in psychosis proneness.     

The ‘Right’ Side of Creativity: Creative Personality and Social Risk-Taking Predict Political Party Affiliation

Factors that predict political party affiliation are of particular importance in research due to the wider implications in politics and policy making. Extending this line of work, the idea that creativity predicts party affiliation was tested using 2 conceptualizations of creativity: creative personality and creative ideation. Participants (N = 406) based in the United States completed measures of creativity, socio-political attitudes, and domain specific risk-taking, and indicated their party affiliation. Results revealed a significant link between creative personality and political party affiliation. Furthermore, in addition to the socio-political attitudes, this link was explained, in part, by individuals’ social risk-taking. Specifically, individuals with higher scores on creative personality were more likely to affiliate to the Democratic party, whereas the reverse was true for affiliation to the Republican party. This article provides new insights into factors that predict political party affiliation and presents wider social implications of the findings.     

Using Daily Creativity Planning to Promote Creative Behavior

Research has demonstrated that on the path from a creative idea to a creative outcome, high creativity motivation and self-efficacy do not necessarily lead to creative behavior. The present study proposed and examined the notion that daily creativity planning could promote creative behavior and contribute to the cultivation of creativity. A total of 77 middle school students (39 students in the experimental group and 38 in the control group) participated in this study, for which a quasi-experimental design was administered. The experimental group conducted a two-week daily planning for creative activities, while the control group did not conduct any intervention. The results showed that students' creativity motivation and creative self-efficacy were at relatively high levels overall and were positively and moderately correlated with creative behavior. Daily planning could effectively facilitate students' creative behavior. These findings point to a promising and simple creativity enhancement strategy for cultivating students to develop the habit of making creative plans in their daily lives.     

Mood—Creativity Relationship in Groups: The Role of Equality in Idea Contribution in Temporal Mood Effects

As people working in groups might fare better in solving complex problems than those working alone (e.g., Laughlin, Hatch, Silver, & Boh, Journal of Personality and Social Psychology, 90 , 2006 and 644), organizations have increasingly assigned creative projects to groups. Group members contribute their collective efforts over time until the creative project has come to fruition. Although mood is identified as an important antecedent to creativity, little is known about the temporal pattern of how group mood enhances or inhibits group creativity, as well as the underpinning group process that explains the mood—creativity link in groups. We set out to address these questions by taking a within-group approach to study the temporal trends of how group mood precedes group creativity and to examine idea contribution equality (ICE) as a mediating group process. We conducted a three-wave longitudinal study among student workgroups tasked to complete a creativity project over a 1-month span. Evidence showed that positive mood is positively associated with concurrent ICE and negative mood is negatively associated with lagged ICE. Furthermore, a mediation model showed that negative mood eventually hampered expert-rated group creative performance by reducing ICE over time. These findings add new knowledge to the temporal mood—creativity relation within the group context.     

Industrial and Biological Analogies Used Creatively by Business Professionals

The objective of this study was to test the effect of far-field industrial (i.e., man-made) versus biological analogies on creativity of business professionals from two organizations engaged in the idea generation phase of new product development. Psychological effects, as reflected in language use, were measured via computerized text analysis of transcribed audio recordings of ideation sessions. Effects on quality of product concepts generated by participants were measured via analysis of 15 judges’ multidimensional creativity ratings. Though psychological effects were undetectable, results suggest presenting new product development professionals with biological analogies as ideation stimulus increases novelty and may increase elegance of solutions generated. Presenting far-field industrial analogies increases relevance and effectiveness of solutions generated. This study serves as a source of evidence that biomimicry (design by analogy to biology) is an effective approach to product innovation. It also shows that there is an important role for far-field industrial analogies in stimulating ideas during new product development. A strategically designed brainstorming session should prime innovators with both far-field industrial and biological analogies to generate maximally creative ideas.     

Indeterminacy and consciousness in the creative process: What quantum physics has to offer

The quantum view of creativity, based on Goswami's idealistic interpretation of quantum physics, is presented. It provides a resolution for two controversial areas of creativity theory and research: the “aha”; experience and the role of consciousness. According to the quantum model, the mind‐brain consists of classical and quantum functions and structures. The source for creative ideation lies in the quantum realm in the form of unlearned coherent superpositions or states of simultaneous multiple possibilities. While access of coherent superpositions (CohS) are susceptible to interference from classical domain functions, such as attention, the CohS itself is experienced as an altered state, facilitating creative ideation. The relationships among attention, self‐awareness, context, ambiguity, uncertainty, and conscious and unconscious perception in creative ideation are proposed to be experienced discontinuously due to an indeterminate element inherent in nature. Theoretical and empirical investigation of the above propositions is possible through quantum physics.     

Creativity in the Age of Technology: Measuring the Digital Creativity of Millennials

Digital technology and its many uses form an emerging domain of creative expression for adolescents and young adults. To date, measures of self-reported creative behavior cover more traditional forms of creativity, including visual art, music, or writing, but do not include creativity in the digital domain. This article introduces a new measure, the Creative Behavior Questionnaire: Digital (CBQD), which assesses self-reported creative behavior in the digital domain. High school students (N = 230) completed the CBQD, as well as several other measures of creativity and personality. Factor analysis revealed 3 factors: digital creativity achievement, school-based everyday creativity, and self-expressive digital creativity. Factor-based scales showed expected correlations with other creativity measures, as well as Big-Five personality traits and Unconventionality, supporting construct validity. Results indicate that the CBQD can be used as an independent or a supplemental measure of creative behavior.     

Boundless Creativity: Evidence for the Domain Generality of Individual Differences in Creativity

This study investigated correlates of domain‐general and domain‐specific components of creativity. 158 college students completed a questionnaire that assessed their motivational and personality traits (i.e., intrinsic and extrinsic motivation, creative personality, and originality in word association) as well as intellectual abilities (SAT verbal and quantitative scores). Under two different instruction conditions (standard instruction or explicit “be creative” instruction), students also took a battery of multi‐item, product‐based tests of creativity in three domains (artistic, verbal, and mathematical creativity). Factor analyses showed evidence of domain‐generality of creativity. Furthermore, results from structural equation models showed that motivational and personality traits and intellectual abilities were associated with the domain‐general component of creativity. Only one variable (SAT quantitative score) was found to be associated with the domain‐specific component of mathematical creativity under the explicit “be creative” instruction condition. These results affirm the domain‐generality of creativity and challenge researchers to identify correlates of domain‐specific components of creativity.     

Predicting Creative Behavior: A Reexamination of the Divergence Between Traditional and Teacher-Defined Concepts of Creativity

Previous research has shown that teachers' identifications of traits associated with the creative personality differ substantially from those typically identified as characteristic of creative individuals. This result has helped resolve the paradox between teachers' self-reports that they enjoy having creative children in their classrooms and the findings that they dislike characteristics such as nonconformity that traditionally are associated with creativity. Nevertheless, it is essential that the predictive utility of teacher-defined concepts of creativity be compared with that of the traditional view to further our understanding of this apparent contradiction. Verbal and figural creativity were measured in 3rd- and 4th-grade children using a story-writing task and a collage task, respectively. Results indicate that children who most closely matched teacher-defined concepts of creativity were most creative in the verbal task but not in the figural task. Conversely, children who most closely mulched the traditional concepts of creativity were highest in figural creativity but not in verbal creativity. These results are discussed in terms of problems of classroom management and the increasing focus on creativity as a domain specific rather than global trait.

Genetic associations with personality and mental toughness profiles of English academy football players: An exploratory study

Psychological characteristics influence the performance of youth football players and are significant predictors of development and success at adulthood. Although genetic factors may explain a considerable portion of inter-individual differences in psychological traits, psychogenetic research in football is scarce. As such, the purpose of this study was to examine the association of ten single nucleotide polymorphisms (SNPs) with personality and mental toughness profiles of academy football players. Seventy-three male under-12 to under-18 football players from a Category 3 English academy were genotyped for ten SNPs. Personality and mental toughness were assessed using a 50-item IPIP Big Five personality traits questionnaire and the Mental Toughness Index, respectively. Simple linear regression was used to analyse individual SNP associations with personality dimensions and mental toughness, whereas both unweighted and weighted total genotype scores (TGSs; TWGSs) were computed to measure the combined influence of all SNPs. There was a significant association between DRD3 (rs167771) and agreeableness (p = .043), where A/A homozygotes scored higher than G allele carriers. TGSs and/or TWGSs were significantly correlated with mental toughness and each personality dimension except openness, explaining between 3 and 17% of the variance. The results of this study suggest psychological characteristics of youth football players are partly determined by genetic factors.
