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.     

Creativity,Originality, and Appropriateness: What do Explicit Instructions Tell Us About Their Relationships?

Originality is a necessary part of creativity, but creative things are more than just original. They also solve a problem, or more generally are somehow fitting or appropriate. Yet previous research found an inverse relationship between ratings of originality and ratings of appropriateness. The present investigation employed a different methodology — it focused on the generation of ideas instead of judgments about them — to reexamine the relationships between originality, appropriateness, and creativity. Undergraduate students (N = 170) from two large universities received either realistic or unrealistic divergent thinking tasks. These were given with one of four types of instructions. These asked them to give (a) as many ideas as possible (which is the standard type of instruction for these kinds of tests), (b) only original ideas, (c) only appropriate ideas, or (d) only creative ideas. Brief definitions of originality, appropriateness, or creativity were also provided. Comparisons of the four groups indicated that there were significant differences between the different kinds of tasks, with the realistic set eliciting more appropriate ideas than the unrealistic, but the unrealistic tasks eliciting more original and varied (flexible) ideas. There was an interaction indicating that the magnitude of the impact of the instructions varied across tasks. Correlational analyses indicated that the correlation between the originality and appropriateness scores was the lowest among all possible inter‐index relationships (only 7% shared variance). Future research and practical implications are explored.     

Divergent Thinking As a Function of Time and Prompting to “Be Creative” in Undergraduates

This study examined divergent thinking in undergraduates as a function of gender, time, and test instruction conditions. Differences were examined in male and female undergraduates when tested on a divergent thinking test with or without prompting to “be creative” and with or without time limitations imposed. Subject groups were assigned to one of the following four conditions: standard instructions/four minute time limit; standard instructions/no time limit; creative instructions/four minute time limit; and creative instructions/no time limit. The no time limit condition resulted in significantly higher mean traditional fluency and flexibility divergent production scores. Males were found to have significantly higher mean divergent production scores on fluency. This study supported previous research findings regarding the lack of enhanced traditional divergent production scores for females resulting from creative instructions.     

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.     

Person-oriented profiles of originality and fluency in divergent thinking responses

Researchers often use divergent thinking tasks to assess creative potential and find a positive inter-individual relation between fluency and originality. But are there different within-person patterns of originality and fluency? Study 1: undergraduates completed an alternate uses task and the NEO-FFI. Three profiles emerged: (1) low originality and fluency; (2) above average originality, moderate fluency; and (3) average originality, high fluency. Study 2: high school students completed a divergent thinking task and 10 facets of the IPIP NEO-PI. Four profiles emerged: (1) average originality, moderate fluency; (2) above average originality, high fluency; (3) low originality and fluency; and (4) high originality, low fluency. Profile differences in personality and maximum originality, and implications of these findings are discussed.     

Divergent Thinking and Evaluation Skills: Do They Always Go Together?

The aim of the present study was to explore the hypothesized relationship between divergent thinking (DT) and two types of evaluation: interpersonal (judgments about others' ideas) and intrapersonal (judgments about one's own ideas). Divergent thinking and evaluation skills were measured by means of a GenEva (Generation and Evaluation) task. There were two conditions of the task: intrapersonal and interpersonal, and two aspects of a given idea were assessed: originality and uniqueness. The main results suggest that (1) overall DT skill is positively related to intrapersonal evaluation of uniqueness; (2) the originality component of DT skill is negatively related to intrapersonal evaluation of uniqueness; (3) overall DT is negatively related to intrapersonal evaluation of originality; (4) underestimation of idea uniqueness is more salient in interpersonal evaluation, particularly in case of those with high DT skill. The results are discussed in terms of author's and observer's perspectives of judgment.     

Assessing Associative Distance Among Ideas Elicited by Tests of Divergent Thinking

Tests of divergent thinking represent the most commonly used assessment of creative potential. Typically they are scored for total ideational output (fluency), ideational originality, and, sometimes, ideational flexibility. That scoring system provides little information about the underlying process and about the associations among ideas. It also does not really capture the key principle of divergent thinking, namely that ideas may be found when cognition explores new (divergent) directions. The investigation reported here used 3 independent semantic networks, each computerized and previously validated, to quantify the distance between responses (ideas) to several tests of divergent thinking. These sources were WordNet (WN), Word Associations Network (WAN), and IdeaFisher (IF). Statistical analyses indicated that remote and close associations can be reliably measured when different sources of associative strength are used. Inter-item reliability (alpha coefficients) of what these networks had identified as remote associations were higher than those from close associations. Inter-item reliability values were higher in the WAN and IF, which provided shorter lists than the WN. Therefore, longer associative lists did not necessarily produce better indices of remote and close associations. Also, scores from a measure of creative attitudes and values were significantly correlated with remote, but not with close, associations across all 3 networks. This finding is very important because it shows that people with a higher tendency of creative attitudes and values, as measured by divergent thinking tests, are more likely to make remote associations rather than close associations. Limitations and future directions are discussed.     

The development of creativity in Chilean kindergarten and school children / Desarrollo de la creatividad en párvulos y escolares chilenos

Abstract

The purpose of this study is to explore the development of creativity in Chilean kindergarten and school children. For this, we evaluated non-verbal divergent and convergent thinking skills in a sample of 320 Chilean kindergarten, second-, fourth- and sixth-grade school children. We found that kindergarten and second-grade children showed a lower performance in creative fluency and originality than fourth-grade and sixth-grade children. In addition, we found that kindergarten and second-grade children had a low performance in creative elaboration, which worsened in the fourth and sixth grades. We did not find differences between the different educational levels in convergent thinking skills. Our results contradict previous international studies that report a stable development of creativity throughout the first few years of schooling, with a transitory slump in the fourth or sixth grade, revealing an early slump of creative skills in Chilean children, which rebound after the fourth grade. We discuss the potential relationship between the academization and rigidization of Chilean early childhood education and the early slump in creativity.     

Creativity and Cognitive Control: Explorations of Generation and Evaluation Skills

Two experiments are reported in which relationships between cognitive control and generative as well as evaluative aspects of creativity were studied. Cognitive control was assessed through the interference effects of the Navon and Stroop tasks. Generative and evaluative aspects of creativity were studied with a procedure, called Generation and Evaluation (GenEva). Each participant first generated a number of solutions to a set of divergent problems, and then he or she evaluated solutions provided by another participant, chosen at random. The data suggest that participants scoring high on Urban and Jellen's Test for Creative Thinking-Drawing Production showed better indexes of cognitive control than participants with lower scores. A similar relationship has been found concerning the originality of participants' productions (GenEva procedure) but not their fluency and flexibility. These findings are interpreted in terms of basic cognitive processes, which are probably responsible for idea production. It also appeared that cognitive control allowed more accurate evaluation of other people's ideas, but only in the case of participants with global cognitive style of information processing.     

Effects of Marijuana Use on Divergent Thinking

This research sought to evaluate the effect of marijuana use on creativity as defined by the term divergent thinking. Another objective was to verify if there was a difference in the creativity of regular users (60 participants) and that of novice users of marijuana (60 participants) under 3 experimental conditions: without marijuana, with placebo, and with marijuana. The 4 divergent thinking factors (fluency, flexibility, originality, and elaboration) were measured by the Torrance Tests of Creative Thinking (Form A, Figural scale). The results showed that the use of marijuana had no positive effects on divergent thinking (creativity) in novice users and reduced it in regular users.     

Creativity in Physics: Response Fluency and Task Specificity

The purpose of this study was to explore creativity in the domain of physics and, specifically, its relation to fluency of responses (divergent thinking) and type of task. Fifty-four university students were pretested on their knowledge of relevant physics concepts. They then were asked to solve 3 ill-defined problems representing different types of tasks. The appropriate responses given to each problem were evaluated as to their number (fluency) and frequency (originality). Task-specific components were found to influence creativity independently and to moderate the effects of general factors such as fluency of responses. Efforts to predict and facilitate creativity in educational settings, therefore, also must take into account the way creativity is manifested within particular domains and the constraints that different types of tasks may impose.     

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.     

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.     

Divergent thinking in Alzheimer's and frontotemporal dementia

Twenty-three patients with mild dementia of the Alzheimer's type (DAT) or frontotemporal type (DFT) and age- and education-matched control subjects were administered tests of complex fluency involving divergent thinking and tests of letter, category, and figural fluency. The tests of complex fluency discriminated the dementia patients from control subjects more strongly than did the other fluency tests. The results suggest that divergent thinking as assessed by complex fluency tests is a cognitive domain that is impaired early in the course of dementia. The sensitivity of complex fluency tests compared to that of letter, category, and figural fluency tests may be related to greater demands for conceptualization in relating stimulus attributes to function and greater demands for flexible thinking during self-directed search processes.     

Short Term Intervention Model for Enhancing Divergent Thinking among School Aged Children

Creative ability can be developed and improved through intervention and training. This study presents a unique and innovative intervention program for enhancing creative thinking among children, focusing on divergent thinking skills. The program was designed as a short-term (10 weeks) training and conducted with 150 school students ranging in age from 9 to 13 years. The training included in a series of assignments, inspired by theoretical and practical concepts of mindfulness, theory of mind, and perspective taking. Divergent thinking was measured by fluency and uniqueness scores according to Tel Aviv Creativity Test (TACT). Results showed that children who participated in the program scored significantly higher on the divergent thinking tests after the intervention took place and that they showed higher creative achievements compared to children in the control groups.     

Divergent Thinking in Alzheimer's and Frontotemporal Dementia

Twenty-three patients with mild dementia of the Alzheimer's type (DAT) or frontotemporal type (DFT) and age- and education-matched control subjects were administered tests of complex fluency involving divergent thinking and tests of letter, category, and figural fluency. The tests of complex fluency discriminated the dementia patients from control subjects more strongly than did the other fluency tests. The results suggest that divergent thinking as assessed by complex fluency tests is a cognitive domain that is impaired early in the course of dementia. The sensitivity of complex fluency tests compared to that of letter, category, and figural fluency tests may be related to greater demands for conceptualization in relating stimulus attributes to function and greater demands for flexible thinking during self-directed search processes.     

On the Conceptual Overlap between the Fluency Contamination Effect in Divergent Thinking Scores and the Chance View on Scientific Creativity

The equal odds baseline is a parsimonious model that describes the relationship between quantity and quality of output in scientific creativity. Specifically, it is posited that quality is a linear function of quantity, and therefore, strong positive correlations between these two variables are expected. Strong positive correlations also play a crucial role in a recurring issue in divergent thinking research: the fluency contamination effect. This effect refers to the problem that any other summative scoring of divergent thinking tests such as the number of original responses (i.e., quality of responses) is confounded by fluency (i.e., quantity of responses). The current work sheds further light into the conceptual overlap between the equal odds baseline, and the fluency contamination effect by demonstrating that a recent formalization of the fluency contamination effect can be used to derive the equal odds baseline. This result is then utilized within a structural equation modeling approach with simulated datasets to thoroughly examine the equal odds baseline. The findings of the structural equation modeling approach are discussed with respect to their potential to better understand the relationship between quantity and quality of productions in creativity research.     

When does feeling of fluency matter?: how abstract and concrete thinking influence fluency effects

It has been widely documented that fluency (ease of information processing) increases positive evaluation. We proposed and demonstrated in three studies that this was not the case when people construed objects abstractly rather than concretely. Specifically, we found that priming people to think abstractly mitigated the effect of fluency on subsequent evaluative judgments (Studies 1 and 2). However, when feelings such as fluency were understood to be signals of value, fluency increased liking in people primed to think abstractly (Study 3). These results suggest that abstract thinking helps distinguish central decision inputs from less important incidental inputs, whereas concrete thinking does not make such a distinction. Thus, abstract thinking can augment or attenuate fluency effects, depending on whether fluency is considered important or incidental information, respectively.     

Measuring creative thinking: An activity‐based approach

The primary objective of this exploratory study was to test activity‐based behavioral measures of creative thinking with a sample of Hong Kong fifth‐grade school children, and also to determine the concurrent validity between activity‐based measures of creative thinking and standard divergent thinking tests. Altogether five creative thinking abilities were measured using the behavioral techniques and the children's scores for fluency, flexibility, and originality were compared with those from the Torrance Test of Creative Thinking (TTCT). The construct‐related validity among all the different abilities on the behavioral measures was also calculated. Contrary to previous assertions about the lack of creativity among Chinese populations, the Hong Kong children demonstrated their ability to use a number of creative thinking features in order to solve problems. No construct validity was found between the different measures of creativity except between originality and fluency. Possible reasons for this are reviewed. The TTCT and the behavioral techniques were found to have some concurrent validity in relationto fluency and originality on the Verbal Tests. There was no correlation for flexibility. The advantages of using activity‐based measurements of creative behavior are discussed.
