Effects of explicit instructions to "be creative" on the psychological meaning of divergent thinking test scores.

The Alternate Uses Test was administered to 50 undergraduate males instructed to produce creative (i.e., novel and worthwhile) uses and to 55 comparable subjects simply instructed to produce as many uses as possible. All uses were rated for creativity. An index of self-assessed creative thinking ability correlated significantly more strongly (p less than .05) with the number of creative uses produced in the qualitatively-oriented condition than with the number of creative or total uses produced in the standard, quantitatively-oriented condition. The correlation between self-rated creative ability and creative uses production in the qualitatively-oriented condition remained significant (p less than .001) after indices of achievement motivation and general verbal aptitude were partialled out. The results were interpreted as demonstrating the value of coordinating informative divergent thinking test instructions with qualitative scoring criteria.     

Intelligence,divergent thinking,and creativity

Guilford's Alternate Uses, Plot Titles, and Consequences tests were given to 94 university students along with the Concept Mastery Test, a traditional measure of verbal intelligence. These measures were correlated with an inventory of creative activities and accomplishments. A composite index of ideational fluency correlated with four creativity indices: Crafts, Performing Arts, Math-Science, and Total Creativity, while the Concept Mastery Test correlated with three indices: Art, Literature, and Total Creativity. With the exception that verbal intelligence was a better predictor of creativity in literature, no statistical difference between the predictive accuracies of ideational fluency and verbal intelligence were found. The need to re-examine the widely accepted association of divergent thinking with creativity was discussed.     

Primary process thinking, divergent thinking, and coping in children

The relationships among primary process thinking, divergent thinking, and coping were investigated in fifth-grade children. Specifically, it was hypothesized from psychodynamic theory that access to and integration of primary process thinking would be positively related to divergent thinking and that both integration of primary process and divergent thinking would be predictive of coping ability. The Rorschach (Holt's scoring system) and Alternate Uses Test (spontaneous flexibility score) were administered to 53 fifth-grade children. Zeitlin's Coping Inventory, a teacher's rating scale, was the coping measure. Results confirmed the hypotheses for boys in that the percentage of primary process and the Adaptive Regression score on the Rorschach were significantly related to divergent thinking, r(27) = .33, p less than .05 and r(27) = .34, p less than .05, respectively. Divergent thinking was significantly related to teachers' ratings of coping ability for boys, r(27) = .58, p less than .01. There were no significant relationships among the variables for girls. These sex differences in the pattern of correlations are consistent with previous findings.     

The contributions of convergent thinking,divergent thinking,and schizotypy to solving insight and non-insight problems

The ability to generate diverse ideas (divergent thinking) is valuable in solving creative problems (e.g., insight problems); yet, however advantageous, this ability is insufficient to solve the problem alone and requires the ability to logically deduce an assessment of correctness of each solution (convergent thinking). Positive schizotypy may help isolate the aspects of divergent thinking prevalent in insight problem solving. Participants were presented with a measure of schizotypy (Oxford-Liverpool Inventory of Feelings and Experiences), divergent and convergent thinking tasks, insight problems, and non-insight problems. We found no evidence for a relationship between schizotypy and insight problem solving. Relationships between divergent thinking and insight problem solving were also surprisingly weak; however, measures of convergent thinking had a stronger relationship with problem solving. These results suggest that convergent thinking is more important than divergent thinking in problem solving.     

Attitudes towards the use of tests and test scores

This exploratory study compared the perceived use of tests and test scores of 43 adult education teachers and 130 teachers in the K-12 system tested earlier.     

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 interrelationship between speeded and unspeeded divergent thinking and reasoning, and the role of mental speed

The relationship between intelligence and creativity is still subject to substantial debate in the research literature. In the present study, we focused on core dimensions of both constructs, that is divergent thinking and reasoning. We hypothesized their relationship to depend both on the speededness of test tasks and on the subject's mental speed, positing that with increasing speededness of the tasks, mental speed would have a stronger impact on task outcomes. We disentangled the effects of task speededness and mental speed experimentally, testing 261 participants (mean age 14.48 years) with 12 divergent thinking and 12 reasoning tasks, 6 of each under power conditions, 6 time-constrained. In addition, we assessed mental speed with 6 tasks. We analyzed the data through structural equation modeling. Results confirmed our expectations: test speededness contributed significantly to mental speed variance in divergent thinking task performance. Divergent thinking assessed under time constraints was fully explained by divergent thinking assessed under power conditions and by mental speed. Divergent thinking and reasoning showed no correlation when controlling for mental speed. Our findings suggest that the correlations between divergent thinking and reasoning are mainly the result of variance both constructs share with mental speed, and that timed versus untimed test-taking plays a minor role.     

Qualitative evaluation of divergent thinking in patients with schizophrenia

Patients with schizophrenia show deficits across a broad spectrum of neurocognitive domains. In particular, deficits in verbal fluency are common. Verbal fluency tests are neuropsychological tests that assess frontal lobe function or executive function but also assess divergent thinking. However, few studies have considered the impairment of verbal fluency from the viewpoint of divergent thinking. To consider the structure of divergent thinking, not only verbal assessments but also non-verbal assessments are indispensable. We administered several fluency tests, the idea fluency test, the design fluency test, and word (letter and category) fluency tests to 26 patients with schizophrenia and 26 healthy control subjects to evaluate divergent thinking in both groups and assessed their responses qualitatively. An acceptable minimal level of intelligence was maintained in the patient group. Although attention and executive functioning were relatively preserved in the subjects with schizophrenia, they demonstrated significant deficits in divergent thinking and had particular difficulty in producing ideas and designs requiring concept flexibility, a conversion of viewpoint, originality, or novelty. Research on deficits in divergent thinking in patients with schizophrenia may contribute to the development of cognitive and behavioral rehabilitation programs.     

Affective expression in children's fantasy play, primary process thinking on the Rorschach, and divergent thinking

The relationships among expression of primary process thinking on the Rorschach, affective expression in fantasy play, and divergent thinking were investigated in first and second grade children. Sixty children received the rorschach (Holt's scoring system), a play task (Affect in Play Scale), and the Alternate Uses Test. Major hypotheses were supported because the amount of primary process thinking on the Rorschach (frequency and percent) was significantly, positively related to amount of affective expression and primary process expression in play. Also, expression of affect in play (frequency, variety, integration, and comfort) was significantly, positively related to divergent thinking, independent of IQ for both boys and girls. On the Rorschach, percent of primary process was significantly related to divergent thinking for boys. The results suggest that the ability to think imaginatively in a free-association style and the ability to have access to affect-laden material are related processes.     

Uric acid and divergent thinking: a possible relationship.

An exploratory investigation of the relationship between serum uric acid levels in male university students and their scores on tests of convergent and divergent thinking was carried out. The data suggested that uric acid levels are lower in highly divergent thinkers than in less divergent. This led to the speculation that uric acid may be an important biochemical precursor of intellectual functioning. If it does affect intellectual functioning, this may result from the action of uric acid as an endogenous cortical stimulant, or possibly from its action as a facilitator of learning.     

Effects of personality and threat of evaluation on divergent and convergent thinking

This study explores the effects of the Big Five personality traits and threat of evaluation on divergent and convergent thinking in a sample of 82 UK students. Results showed that Openness and Extraversion predicted divergent thinking under both threat of evaluation and no evaluation, whilst Neuroticism correlated significantly with divergent thinking (negatively) only under threat of evaluation. However, mediational analysis showed that the effects of Neuroticism on divergent thinking under threat of evaluation were fully accounted for by Extraversion. Thus neurotics’ divergent thinking was significantly more impaired because they were more introverted. Theoretical and practical implications are discussed.     

Cognitive extension,enhancement, and the phenomenology of thinking

This paper brings together several strands of thought from both the analytic and phenomenological traditions in order to critically examine accounts of cognitive enhancement that rely on the idea of cognitive extension. First, I explain the idea of cognitive extension, the metaphysics of mind on which it depends, and how it has figured in recent discussions of cognitive enhancement. Then, I develop ideas from Husserl that emphasize the agential character of thought and the distinctive way that conscious thoughts are related to one another. I argue that these considerations are necessary for understanding why forms of cognitive extension may diminish our cognitive lives in different ways. This does not lead to a categorical rejection of cognitive enhancement as unethical or bad for human flourishing, but does warrant a conservative approach to the design and implementation of cognitive artifacts.     

Social cues for creativity: The impact of behavioral mimicry on convergent and divergent thinking

We present behavioral mimicry as a social cue for creative thinking. Specifically, we argue that being mimicked by an interaction partner cues convergent thinking by signalling a social opportunity for collaboration, while not being mimicked cues divergent thinking by signalling a social demand for improvisation and innovation. To test this theory, we experimentally manipulated whether individuals were subtly mimicked or not by an experimenter during a 5 min social interaction, and subsequently measured participants’ capacity for convergent thinking (Experiment 1) and divergent thinking (Experiment 2). The results point to the importance of understanding how social relationships influence the creative processes and contributes to the growing understanding of the social function of behavioral mimicry.     

The development of creative cognition across adolescence: distinct trajectories for insight and divergent thinking

We examined developmental trajectories of creative cognition across adolescence. Participants (N = 98), divided into four age groups (12/13 yrs, 15/16 yrs, 18/19 yrs, and 25–30 yrs), were subjected to a battery of tasks gauging creative insight (visual; verbal) and divergent thinking (verbal; visuo‐spatial). The two older age groups outperformed the two younger age groups on insight tasks. The 25–30‐year‐olds outperformed the two youngest age groups on the originality measure of verbal divergent thinking. No age‐group differences were observed for verbal divergent thinking fluency and flexibility. On divergent thinking in the visuo‐spatial domain, however, only 15/16‐year‐olds outperformed 12/13‐year‐olds; a model with peak performance for 15/16‐years‐old showed the best fit. The results for the different creativity processes are discussed in relation to cognitive and related neurobiological models. We conclude that mid‐adolescence is a period of not only immaturities but also of creative potentials in the visuo‐spatial domain, possibly related to developing control functions and explorative behavior.     

Children's original thinking: an empirical examination of alternative measures derived from divergent thinking tasks

Children's creative potential is often assessed using cognitive tests that require divergent thinking, such as the Torrance Tests of Creative Thinking (TTCT; E. P. Torrance, 1974, 1976, 1990). In this study the authors investigated the effect of various scoring systems on the originality index, evaluating the high intercorrelation of fluency and originality measures found in the TTCT scoring system and the applicability of TTCT scoring norms over time and across age groups. In 3 studies, the originality of elementary school children was measured using TTCT norms and various sample-specific scoring methods with the TTCT Unusual Uses of a Box test as well as social-problem-solving tasks. Results revealed an effect of scoring technique on creativity indices as well as on the reliability of originality scores and the relationship between originality and other ability measures. The usefulness of the various measures for understanding children's original thinking are discussed.
