Revisiting Mednick's Model on Creativity‐Related Differences in Associative Hierarchies. Evidence for a Common Path to Uncommon Thought

Fifty years ago, Mednick [Psychological Review, 69 (1962) 220] proposed an elaborate model that aimed to explain how creative ideas are generated and why creative people are more likely to have creative ideas. The model assumes that creative people have flatter associative hierarchies and as a consequence can more fluently retrieve remote associative elements, which can be combined to form creative ideas. This study aimed at revisiting Mednick's model and providing an extensive test of its hypotheses. A continuous free association task was employed and association performance was compared between groups high and low in creativity, as defined by divergent thinking ability and self‐report measures. We found that associative hierarchies do not differ between low and high creative people, but creative people showed higher associative fluency and more uncommon responses. This suggests that creativity may not be related to a special organization of associative memory, but rather to a more effective way of accessing its contents. The findings add to the evidence associating creativity with highly adaptive executive functioning.     

The roles of associative and executive processes in creative cognition

How does the mind produce creative ideas? Past research has pointed to important roles of both executive and associative processes in creative cognition. But such work has largely focused on the influence of one ability or the other—executive or associative—so the extent to which both abilities may jointly affect creative thought remains unclear. Using multivariate structural equation modeling, we conducted two studies to determine the relative influences of executive and associative processes in domain-general creative cognition (i.e., divergent thinking). Participants completed a series of verbal fluency tasks, and their responses were analyzed by means of latent semantic analysis (LSA) and scored for semantic distance as a measure of associative ability. Participants also completed several measures of executive function—including broad retrieval ability (Gr) and fluid intelligence (Gf). Across both studies, we found substantial effects of both associative and executive abilities: As the average semantic distance between verbal fluency responses and cues increased, so did the creative quality of divergent-thinking responses (Study 1 and Study 2). Moreover, the creative quality of divergent-thinking responses was predicted by the executive variables—Gr (Study 1) and Gf (Study 2). Importantly, the effects of semantic distance and the executive function variables remained robust in the same structural equation model predicting divergent thinking, suggesting unique contributions of both constructs. The present research extends recent applications of LSA in creativity research and provides support for the notion that both associative and executive processes underlie the production of novel ideas.     

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.     

Crossing Cultures: Training Effects on the Divergent Thinking Attitudes of Spanish-Speaking South American Managers

ABSTRACT: Field experiments investigated the effects of training Spanish-speaking South American managers in creative thinking and problem solving. The Spanish translations of two attitude measures associated with divergent thinking practice (an important aspect of creative thinking and problem solving) were tested and validated. The two attitudes were measured both before and after training. The results indicate that the concepts and methods of similar training provided in previous Japanese and North American research are applicable to Spanish-speaking South American managers. The first experimental group (n = 149) showed significant gains on both measures versus a placebo control group. The second and third experimental groups (n = 54 and n = 14) were given revised versions of the 14-item questionnaire, and the results showed significant improvement in the reliability of the Spanish translations. Future directions for research include increasing the reliability of the Spanish versions of the two attitudinal measures and extending the training effect investigation beyond attitude changes to include behavior changes and long-term persistence and portability to the job.     

How Creativity Was Affected by Environmental Factors and Individual Characteristics: A Cross-cultural Comparison Perspective

The purpose of this study was to explore how environmental factors (family environment and school education) and individual characteristics (personality, creative attitudes, and divergent thinking) collectively affect creative achievement of American and Chinese college students. Data were collected from 378 college students in the United States (N = 193) and China (N = 185). Results showed that the US sample had significantly higher means in home resources, high-school education, Conscientiousness, creative achievement, and all four dimensions of the Abbreviated Torrance Test for Adults (ATTA) than the China sample. In contrast, the China sample scored significantly higher in understanding the importance of creativity. Results indicated creative attitudes and divergent thinking sequentially mediated the effects of parental values on creative achievement for the US sample, whereas Openness mediated the effect of high-school education on creative achievement for the China sample. For both samples, creative attitudes mediated the effect of Openness on divergent thinking. The results suggested cultural differences in the effects of environmental factors on creativity, yet more similar findings in the effects of individual characteristics on creativity between the two samples. The results and implications are discussed.     

Flexibility and Originality in Children's Divergent Thinking

Previous research on the ideational process indicates that original ideas increase in frequency as an examinee works through an open-ended task. In the present investigation, ideational flexibility was evaluated to determine if ideas also become more varied and diverse. Additionally, the relationship of intelligence (IQ) with order effects of both originality and flexibility was investigated. Tests of verbal and figural divergent thinking were administered to 80 intermediate school children. The midpoint of each individual's ideational set was found, and the flexibility and originality scores of each half of the set were compared. Results indicated that flexibility and originality scores were higher in the second half than the first half of the ideational set, but there were significant differences between high- and low-originality subjects and differences between the verbal and the figural tests. The order effect was unrelated to the IQ scores of the subjects. Suggestions are made to integrate ideational flexibility into existing theories of divergent ideation.     

Maternal teaching techniques and preschool children's ideational fluency

As a counterpart to research showing relationships between parental behaviors and attitudes and children's divergent thinking, this study investigated mothers’ teaching techniques and preschool children's ideational fluency, one aspect of creativity. Twenty mother‐child dyads were videotaped interacting in both a warm‐up and structured teaching session. Mothers’ teaching behaviors were assessed with the Maternal Teaching Observation Technique (MTOT) and children's ideational fluency was measured with the Multidimensional Stimulus Fluency Measure (MSFM). Correlational analyses indicated relationships between children's divergent thinking and mothers’ use of verbal negative feedback (r = .51), physical control (r = ‐.40), and visual cues (r = ‐.44).     

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。     

The Effects of a Verbal and a Figural Creativity Training on Different Facets of Creative Potential

This study investigated the effects of different types of creativity interventions on different facets of creative potential, also including more school-related creativity demands. In a sample of 77 fourth-graders in the age between 9 and 12 years, we administered a verbal and a figural creativity training, realized in two school lessons over two consecutive days each. As outcome measures, creative potential in both the verbal and the figural domain by means of two well-established divergent thinking tasks was assessed. As additional measures of creative potential, a story completion task and a picture painting task were administered to examine training effects on more school-related types of creative behavior. The verbal training was found to increase both verbal and figural divergent thinking ability, but not creative potential in the story completion and the picture painting task. The figural training yielded significant training effects only regarding the picture painting task. Findings suggest a specific training effect of the figural creativity training, and moreover indicate that the verbal creativity training, rather than stimulating “verbal” creative abilities per se, was more strongly concerned with domain-general creativity processes including ideational fluency, flexibility, and originality that are characteristics of divergent thinking tasks across different domains.     

Cognitive Abilities and Creative Behaviors: CAB-5 and Consequences

The validity of six indices of divergent production is examined with reference to creative output in eight content domains: visual arts, music, literature, theater, science and engineering, business ventures, apparel design, and video and photographic work. Undergraduates (n = 144) completed Consequences, four scales from the Comprehensive Ability Battery, and a specially developed self-report inventory that produced eight creative content scores and a total score. Correlational analysis determined that Semantic Fluency, Ideational Fluency, Originality and Remote Consequences were substantially correlated with most creative behaviors and were uncorrelated with grade point average. A factor analysis of criteria revealed two underlying patterns of creativity, suggesting that proficiency in one creative domain is predictive of proficiency in several others. The study of creativity has traditionally been propelled by aesthetic, scientific, and economic concerns. While revolutionary breakthroughs in science, technology, and design often command our attention and respect, it is the small, evolutionary innovations that typically have the greatest immediate economic impact (Haustein, 1981). From any vantage point there has always been an interest in the prediction and measurement of creative behavior and aptitude. The available measurement approaches for creativity include cognitive abilities, personality traits, self-reports of creative behavior and peer and teacher ratings of creative works (Hocevar, 1981). The purpose of this study is to assess the validity of an underresearched set of cognitive measures: four subtests of the Comprehensive Ability Battery (CAB-5; Hakstian & Cattell, 1976) and the Consequences test (Christensen, Merrifield, & Guilford, 1958). Our validity strategy was correlational; criteria were eight self-report indices of creative endeavor. The following paragraphs elaborate the underlying theory from which these measures originated and some unresolved issues. Perhaps the largest single breakthrough in the cognitive approach to understanding creativity came from Guilford's (1967) 120-factor structure of intellect model. While commonly used intelligence tests measure convergent forms of thinking, creativity involves divergent thought processes which, according to Guilford, account for 30 of the 120 factors of intelligence. Working through a factor analytic paradigm, Guilford was able to identify over 100 out of 120 factors. Guilford's structure of intellect may be criticized for having fractured intellectual functioning into too narrowly defined units relative to what human faculties are actually engaged in ordinary intellectual endeavors. Nonetheless, the theory did provide a provocative explanation for the nature of creative thought and some interesting measurements of same. Measurements of creative thought (divergent production) involve word fluency, category formation and reformation, ideational fluency original uses for common objects (opposite of functional fixedness). One test, Consequences (Christensen et al., 1958), is of particular concern to this research project and involves a certain amount of social awareness on the part of the examinee in conjunction with divergent production. In a typical test item, examinees are presented with a hypothetical situation, “What would be the consequences if people no longer needed to sleep?” along with a few common responses. Examinees are then given five minutes to write as many consequences of the hypothetical situation as they can think of. Responses are scored by, first, eliminating responses that are redundant with the samples or other responses or that are completely irrelevant Remaining responses are then categorized as obvious and remote. The numbers of obvious and remote responses are counted to produce two scores. Consequences continues to be listed as a research instrument by its publisher. Norms in the manual (Guilford & Guilford, 1980) are only available for 331 engineers who took two forms of the test, 665 ninth-graders, 80 twelfth graders, and a college sample of 87 cases. According to Guilford & Guilford, the consequences scores are closely related to other divergent production measures, remote more so than obvious. The CAB-5 developed by Hakstian & Cattell (1976, 1978) who also worked in the factor analytic mode, consists of 20 subscales that appear to capture the essentials of convergent and divergent thinking in a timed battery of manageable size. The four divergent thinking scales — semantic fluency, ideational fluency, word fluency, and originality — are of particular interest to this project While the usual types of validity and norm-building research have been done with the convergent scales (Hakstian & Cattell, 1976; Hakstian & Woolsey, 1985) little external validation work is available for the divergent scales. Hakstian & Woolsey (1985) found that semantic fluency and ideational fluency were significantly correlated with grades in an introductory psychology course (r = .33 and .30 respectively). The rationale for why divergent production would be related to grades in that course was vague. Norms for the divergent scales are currently available for 216 college and 1098 high school students. While the validation question is framed around a limited set of scales in this research project, it does represent an issue of more general concern. According to Storfer (1990), several researchers have questioned whether measures of divergent production have any external validity with actual creative works. He cited a study where teachers' ratings of their students' creativity were based on logical or convergent measures but had no relationship to divergent measures. In his review of creativity measures, Hocevar (1978) noted a generally low level of interrelationship among personality, cognitive, self-report, and rating measures of creativity; from this trend he opined that self-report measures of creative behavior were perhaps the most defensible indices of creativity. On the other hand, a study of approximately 500 college students showed that those that had won science prizes, or who published or exhibited their work scored higher than others on ideational fluency (Wallach & Wing, 1969). While the latter finding is reassuring, we are not convinced that prizes, publication, or exhibition represent the full range of creative behavior to be found at the college level. Prizes require a propensity to compete among the participants, and a proclivity toward subjectivity, among the judges. As academic researcher know, earth-shattering ideas are not quickly snapped up by scientific journals, and much of what is published is indicative of the evolutionary progress mentioned at the outset of this article. There is reason to assume that there is much valuable creative effort taking place that does not reach wide audiences or that is otherwise shoved into drawers. From a statistical point of view, it is preferable to conduct a criterion related validity study that encompasses a wide (if not complete) range of criterion values and to avoid an extreme groups methodology, such as a comparison of prizewinners and others. The latter has the impact of exaggerating the predictor-criterion effect size. Altogether, Hocevar (1981) identified 15 studies showing a positive relationship between divergent production and other measures of creativity, and 15 other studies that showed no such relationship. With the foregoing theoretical and methological points in mind, the following hypotheses were examined: 1. Consequences and CAB-5 divergent scale scores would be significantly related to several types of creative behavior. 2. Consequences and CAB-5 divergent scale scores would be significantly related to each other. 3. There would be a substantial interrelationship among the various types of creative behavior. Significant findings would dispel the notion among critics of divergent thinking theory (cf. Stolper, 1990) that the prediction of creativity is situationally specific. 4. Divergent measures and indices of creative behavior would not be related to college students' grade point average (GPA). While we recognize that no point is proven by failing to reject the null hypothesis, a null relationship with GPA is expected from the general theory, on the basis of findings concerning teachers' rates cited in Stolper (1990) and our own assumptions that much creative work goes unnoticed in favor of traditional academic demand. An expected null relationship thus adds an element of convergent-discriminant validity analysis to the research plan.     

Sex differences in instructions to "be creative" on divergent and nondivergent test scores

Harrington (1975) found that both the magnitude and meaning of male subject scores on the Alternate Uses Test were altered by explicit instructions to “be creative,” and argued for the necessity of such instructions, plus qualitative scoring criteria, in the employment of tests of creativity. The present study elaborated upon this study by including female subjects, more than one test of divergent thinking and a test of nondivergent thinking. Instructions to be creative increased the proportion of creative responses output for both males and females, and sharpened correlations with Adjective Check List personality scales. Instructions did not alter performance on the nondivergent test. These results were interpreted to mean the instructions elicited strategies particularly relevant to divergent thinking and ruled out nonspecific effects such as those due to motivation. A reliable sex-difference in ideational fluency was also observed: instructions to be creative facilitated the total number of responses output for the male subjects. This supports a hypothesis that the instructions disambiguate I he test situation differently for men and women, suggesting the need to isolate individual conceptions of creativity in order to maximize test performance.     

Spontaneous eye blinks during creative task correlate with divergent processing

Creativity consists of divergent and convergent thinking, with both related to individual eye blinks at rest. To assess underlying mechanisms between eye blinks and traditional creativity tasks, we investigated the relationship between creativity performance and eye blinks at rest and during tasks. Participants performed an alternative uses and remote association task while eye blinks were recorded. Results showed that the relationship between eye blinks at rest and creativity performance was compatible with those of previous research. Interestingly, we found that the generation of ideas increased as a function of eye blink number during the alternative uses task. On the other hand, during the remote association task, accuracy was independent of eye blink number during the task, but response time increased with it. Moreover, eye blink changes in participants who responded quickly during the remote association task were different depending on their resting state eye blinks; that is, participants with many eye blinks during rest showed little increasing eye blinks and achieved solutions quickly. Positive correlations between eye blinks during creative tasks and yielding ideas on the alternative uses task and response time on the remote association task suggest that eye blinks during creativity tasks relate to divergent thinking processes such as conceptual reorganization.     

Creative Thinking From An Information Processing Perspective: A New Approach To Mednick's Theory Of Associative Hierarchies

Mednick (1962) proposed a theory of the creative thinking process which asserts that in generating associative responses to a stimulus, creative individuals are characterized by a flatter associative hierarchy than are less creative individuals. In order to assess this idea, an associative priming paradigm was used to measure latencies to lexical decisions primed by associations of low, medium, or high strength. Mednick's theory was not supported. However, it was found that the responses of creative subjects were uniformly less facilitated at all levels of associative strength. The set of associative strengths employed in the experiment may not have ranged low enough to provide a realistic test of creative processes. If so, then the obtained findings may be consistent with Mednick's theory as it applies to the upper end of the associative continuum.     

The Effect of Changes in the Temperature and Humidity of the Air on the Apparent Skin Resistance

The effects of affective expression on divergent thinking performance were studied in 40 male and female graduate education students. Divergent thinking was operationally defined in terms of the ideational fluency and originality dimensions of Guilford's (4) Plot Titles test. Experimental group E1, in which emotional states were related to visual stimuli, produced significantly more original responses than experimental group E2 (p < .025), in which the same visual patterns viewed in terms of their geometrical-technical dimensions, and control group C1 (p < .01), in which no training was administered. Groups E2 and C1 demonstrated no significant differences. The groups did not differ with respect to ideational fluency. Verbal ability was a poor predictor of individual differences in ideational fluency and originality. The results suggest an effective approach toward fostering originality and indicate that nonintellective variables may be significant in the creative process.     

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.     

In Praise of Convergent Thinking

ABSTRACT: Free production of variability through unfettered divergent thinking holds out the seductive promise of effortless creativity but runs the risk of generating only quasicreativity or pseudocreativity if it is not adapted to reality. Therefore, creative thinking seems to involve 2 components: generation of novelty (via divergent thinking) and evaluation of the novelty (via convergent thinking). In the area of convergent thinking, knowledge is of particular importance: It is a source of ideas, suggests pathways to solutions, and provides criteria of effectiveness and novelty. The way in which the 2 kinds of thinking work together can be understood in terms of thinking styles or of phases in the generation of creative products. In practical situations, divergent thinking without convergent thinking can cause a variety of problems including reckless change. Nonetheless, care must be exercised by those who sing the praises of convergent thinking: Both too little and too much is bad for creativity.     

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     

Strengthening Creative Problem-Solving within Upper-Elementary Science Education

This intervention study examined the effectiveness of instructional support tailored toward two techniques (i.e., random associations and constraint identification) to strengthen children's creative problem-solving skills within upper-elementary science education. Five inquiry-based science lessons with ample opportunity for creative problem-solving (i.e., divergent and convergent thinking) were provided. Children were assigned to a condition with instructional support (n = 107) or without (n = 134). Domain-general and specific measures of divergent and convergent thinking were included, and reading comprehension as well as mathematical ability were taken into account. Repeated measures multivariate analyses of covariance revealed how all children improved in terms of domain-general convergent thinking, with a larger increase for children who performed better in mathematics. This shows a promising premise for future research focusing on the domain generality of convergent thinking and for the potential of transfer across domains. No additional improvement based on instructional support was found and children did not improve in terms of divergent thinking. The constraint identification and random associations technique might not be suitable for elementary school children, yet future research is necessary to validate such claims. Meanwhile, teachers could possibly support convergent thinking by simply providing exercises for divergent and convergent thinking.     

Loose but normal: a semantic association study

An abnormal facilitation of the spreading activation within semantic networks is thought to under-lie schizophrenics' remote associations and referential ideas. In normal subjects, elevated magical ideation (MI) has also been associated with a style of thinking similar to that of schizotypal subjects. We thus wondered whether normal subjects with a higher MI score would judge "loose associations" as being more closely related than do subjects with a lower MI score. In two experiments, we investigated whether judgments of the semantic distance between stimulus words varied as a function of MI. In the first experiment, random word pairs of two word classes, animals and fruits, were presented. Subjects had to judge the semantic distance between word pairs. In the second experiment, sets of three words were presented, consisting of a pair of indirectly related, or unrelated nouns plus a third noun. Subjects had to judge the semantic distance of the third noun to the word pair The results of both experiments showed that higher MI subjects considered unrelated words as more closely associated than did lower MI subjects. We conjecture that for normal subjects high on MI "loose associations" may not be loose after all. We also note that the tendency to link uncommon, nonobvious, percepts may not only be the basis of paranormal and paranoid ideas of reference, but also a prerequisite of creative thinking.     

Positive mood enhances divergent but not convergent thinking

A positive mood enhances creative performance. We examined which type of creativity, divergent or convergent thinking, was enhanced by a positive mood. Half of the participants listened to happy music and thought about happy events (positive group). The other half listened to the Japanese Constitution (neutral group). Participants' emotional valence and arousal were measured before and after mood induction. All participants then engaged in a creative activity involving the generation of new names for rice. The results indicated that the positive group produced more divergent ideas than did the neutral group. On the other hand, the two groups did not differ with respect to the number of convergent ideas that were generated. We suggest that being in a positive mood facilitates flexible thinking and consequently leads to production of unconventional and atypical ideas.
