The Effects of Affect Manipulation and Information Exposure on Divergent Thinking

This study examined how affective states and exposure to diverse information influence figural divergent thinking using a pretest-posttest design. A total of 148 participants were divided into 4 conditions: positive affect, negative affect, information, and control. In the positive and negative affect conditions, participants respectively listened to the elation and depression statements of the Velten procedure. In the information condition, participants listened to the neutral statements of the Velten procedure. In the control condition, participants listened to word-processing instructions. Divergent thinking was measured using the figural form of the Torrance Tests of Creative Thinking (TTCT), and affect was measured using a mood questionnaire and the State-Trait Anxiety Inventory. Multivariate analyses of covariance were conducted using the TTCT, mood, and state-trait anxiety premeasures as covariates; the TTCT, mood, and state-trait anxiety postmeasures as the dependent variables; and treatment condition as the independent variable. Results showed a significant effect of condition on posttreatment TTCT scores, F(3, 140) = 3.37, p = .0203; mood, F(3, 140) = 7.44, p = .0001; and state anxiety, F(3, 140) = 6.27, p = .0005. Comparison tests showed that the information exposure treatment resulted in significantly higher TTCT scores than the control condition, indicating that exposure to diverse information can enhance divergent thinking. Results further indicated that, although the positive affect manipulation was effective in enhancing mood and reducing state anxiety, it did not enhance divergent thinking scores. The negative affect manipulation did not appear to be effective. Possible explanations for these results are discussed.     

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.

Percolating ideas: The effects of caffeine on creative thinking and problem solving

Caffeine is the most widely consumed psychotropic drug in the world, with numerous studies documenting the effects of caffeine on people’s alertness, vigilance, mood, concentration, and attentional focus. The effects of caffeine on creative thinking, however, remain unknown. In a randomized placebo-controlled between-subject double-blind design the present study investigated the effect of moderate caffeine consumption on creative problem solving (i.e., convergent thinking) and creative idea generation (i.e., divergent thinking). We found that participants who consumed 200 mg of caffeine (approximately one 12 oz cup of coffee, n = 44), compared to those in the placebo condition (n = 44), showed significantly enhanced problem-solving abilities. Caffeine had no significant effects on creative generation or on working memory. The effects remained after controlling for participants’ caffeine expectancies, whether they believed they consumed caffeine or a placebo, and changes in mood. Possible mechanisms and future directions are discussed.     

The (Dis)Pleasures of Creativity: Spontaneous Eye Blink Rate during Divergent and Convergent Thinking Depends on Individual Differences in Positive and Negative Affect

Previous research has demonstrated that individual differences in affect and motivation predict divergent and convergent thinking performance, two thinking processes involved in creative idea generation. Individual differences in affect and motivation also predict spontaneous eye blink rate (sEBR) during divergent and convergent thinking; and sEBR predicts divergent and convergent thinking performance. This study investigates experimentally whether the relationship between sEBR and divergent and convergent thinking depends on individual differences in affect and motivation. Eighty-two participants completed the Emotion/motivation-related Divergent and Convergent thinking styles Scale (EDICOS; G. Soroa et al., 2015), performed the alternative uses task (AUT; divergent thinking) or the remote associates task (RAT; convergent thinking), while their sEBR was captured with an eye-tracker. The results showed that individual differences in positive affect positively correlated with sEBR for the AUT, whereas individual differences in negative affect positively correlated with sEBR for the RAT. Furthermore, the interaction between individual differences in positive and negative affect and sEBR predicted divergent and convergent thinking performance. The contribution of our study is therefore that individual differences in positive and negative affect can both positively correlate with sEBR during divergent and convergent thinking; and that this predicts divergent and convergent thinking performance.     

Unraveling Effects of Novelty on Creativity

Novelty is inherent to creative processes. A positive effect of novelty on creative task performance was therefore predicted. However, creativity can benefit from divergent, as well as convergent thinking. Subsequently, novelty may benefit creative performance when divergent thinking is required, but it could inhibit creative performance when convergent thinking is required. In Study 1, participants were primed with novelty or familiarity, and performed a creativity task that required divergent thinking. Results showed a beneficial effect of novelty priming on originality of the answers. In Study 2, a creativity task that required convergent thinking was framed as novel, familiar, or neutral. Results showed an inhibitory effect of novelty on creativity. Results are related to information processing styles, and implications for creativity and novelty research are discussed.     

不同冥想类型对创造性思维的影响及作用机制

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

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.

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.     

Emotional language processing: how mood affects integration processes during discourse comprehension

This research tests whether mood affects semantic processing during discourse comprehension by facilitating integration of information congruent with moods’ valence. Participants in happy, sad, or neutral moods listened to stories with positive or negative endings during EEG recording. N400 peak amplitudes showed mood congruence for happy and sad participants: endings incongruent with participants’ moods demonstrated larger peaks. Happy and neutral moods exhibited larger peaks for negative endings, thus showing a similarity between negativity bias (neutral mood) and mood congruence (happy mood). Mood congruence resulted in differential processing of negative information: happy mood showed larger amplitudes for negative endings than neutral mood, and sad mood showed smaller amplitudes. N400 peaks were also sensitive to whether ending valence was communicated directly or as a result of inference. This effect was moderately modulated by mood. In conclusion, the notion of context for discourse processing should include comprehenders’ affective states preceding language processing.     

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.     

Convergent and divergent thinking in verbal analogy

Individual differences in convergent and divergent thinking may uniquely explain variation in analogical reasoning ability. Across two studies we investigated the relative influences of divergent and convergent thinking as predictors of verbal analogy performance. Performance on both convergent thinking (i.e., Remote Associates Test) and divergent thinking (i.e., Alternative Uses Task) uniquely predicted performance on both analogy selection (Studies 1 and 2) and analogical generation tasks (Study 2). Moreover, convergent and divergent thinking were predictive above and beyond creative behaviours in Study 1 and a composite measure of crystallised intelligence in Study 2. Verbal analogies in Study 2 also varied in semantic distance, with results demonstrating divergent thinking as a stronger predictor of analogy generation for semantically far than for semantically near analogies. Results thus further illuminate the link between analogical reasoning and creative cognition by demonstrating convergent and divergent thinking as predictors of verbal analogy.     

Are Speedy Brains Needed when Divergent Thinking is Speeded—or Unspeeded?

In this study, we focus on mental speed and divergent thinking, examining their relationship and the influence of task speededness. Participants (N = 109) completed a set of processing speed tasks and a test battery measuring divergent thinking. We used two speeded divergent-thinking tasks of 2 minutes and two unspeeded tasks of 8 minutes to test the influence of task speededness on creative quality and their relation to mental speed. Before each task, participants were instructed to be creative in order to optimally measure creative quality. We found a large main effect of task speededness: less creative ideas were generated when tasks were speeded as compared to unspeeded (Cohen's d = −1.64). We could also replicate a positive relationship of mental speed with speeded divergent thinking (r = .21) and mental speed with unspeeded divergent thinking (r = .25). Our hypothesis that the relation is higher for the speeded divergent-thinking tasks was not confirmed. Importantly, variation in creative quality scores under speeded conditions was not explained by mental speed beyond the predictive power of unspeeded creative quality. The latter finding implies that measurement of creative quality under speeded conditions is not confounded by mental speed.     

Enhanced divergent thinking and creativity in musicians: a behavioral and near-infrared spectroscopy study

Empirical studies of creativity have focused on the importance of divergent thinking, which supports generating novel solutions to loosely defined problems. The present study examined creativity and frontal cortical activity in an externally-validated group of creative individuals (trained musicians) and demographically matched control participants, using behavioral tasks and near-infrared spectroscopy (NIRS). Experiment 1 examined convergent and divergent thinking with respect to intelligence and personality. Experiment 2 investigated frontal oxygenated and deoxygenated hemoglobin concentration changes during divergent thinking with NIRS. Results of Experiment 1 indicated enhanced creativity in musicians who also showed increased verbal ability and schizotypal personality but their enhanced divergent thinking remained robust after co-varying out these two factors. In Experiment 2, NIRS showed greater bilateral frontal activity in musicians during divergent thinking compared with nonmusicians. Overall, these results suggest that creative individuals are characterized by enhanced divergent thinking, which is supported by increased frontal cortical activity.     

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

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

Can positive affect induce self-focused attention? Methodological and measurement issues

Some studies find that positive affect can induce self-focused attention, but other studies find no effect. We suggest that the contrary findings result from how self-awareness was measured. One group of participants listened to happy or neutral music; another group imagined and described a happy or neutral event. Two measures of self-focus were then taken. The experiment replicated past findings: Positive affect increased self-focus on a pronoun selection task, but had no effect on a modified private self-consciousness scale. The results were slightly stronger when affect was induced using music. Implications for future research are discussed.     

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。     

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.     

Affective Induction and Creative Thinking

Three studies explored the relation between affect and production of creative divergent thinking, assessed with the Torrance Tests of Creative Thinking (Figural TTCT). In the first study, general, positive, and negative affect, assessed with the Positive and Negative Affect Scale (PANAS) were compared with creative production. In the second study, 2 affective states—happiness and sadness—were induced by means of 2 film sets, and creative production under these 2 conditions was compared. In the third study, using masked facial feedback, 2 affective states were induced: happiness—by requesting participants to hold a pencil in their teeth—and anger—by holding it with their lips—and creative production under both induced affects, as well as with a previous noninduced affect, was compared. In general terms, the results of all 3 studies show that positive affect, both general positive affect and the happy affect induced in the two experimental manipulations, increased the production of creative divergent thinking. Negative affect had no impact on the production of creative divergent thinking, neither general negative affect nor the experimentally induced affects of sadness and anger. In masked induction, the induced positive affect improved creative production, compared to the noninduced control situation; in contrast, the induced negative affect presented no differences in creative production, compared to its previous noninduced condition.
