RESUMO

By examining the shared neuro-cognitive correlates of curiosity and creativity, we better understand the brain basis of creativity. However, by only examining shared components, important neuro-cognitive correlates are overlooked. Here, we argue that any comprehensive brain model of creativity should consider multiple cognitive processes and, alongside the interplay between brain networks, also the neurochemistry and neural oscillations that underly creativity.

RESUMO

Catecholamine-enhancing psychostimulants, such as methylphenidate have long been argued to undermine creative thinking. However, prior evidence for this is weak or contradictory, stemming from studies with small sample sizes that do not consider the well-established large variability in psychostimulant effects across different individuals and task demands. We aimed to definitively establish the link between psychostimulants and creative thinking by measuring effects of methylphenidate in 90 healthy participants on distinct creative tasks that measure convergent and divergent thinking, as a function of individuals' baseline dopamine synthesis capacity, indexed with 18F-FDOPA PET imaging. In a double-blind, within-subject design, participants were administered methylphenidate, placebo or selective D2 receptor antagonist sulpiride. The results showed that striatal dopamine synthesis capacity and/or methylphenidate administration did not affect divergent and convergent thinking. However, exploratory analysis demonstrated a baseline dopamine-dependent effect of methylphenidate on a measure of response divergence, a creativity measure that measures response variability. Response divergence was reduced by methylphenidate in participants with low dopamine synthesis capacity but enhanced in those with high dopamine synthesis capacity. No evidence of any effect of sulpiride was found. These results show that methylphenidate can undermine certain forms of divergent creativity but only in individuals with low baseline dopamine levels.

RESUMO

Awe is a fascinating emotion, associated with positive consequences such as greater prosociality, generosity, and epistemic openness. Unfortunately, in spite of the weighty consequences of awe, the exact way in which it arises, and what it entails, is still a puzzle. Particularly puzzling is the question of whether awe is the result of expectancy violation. While awe is thought to arise in reaction to expectancy-violating objects or events, classical expectancy violations (e.g., a red queen of spades playing card) do not tend to cause awe. To shed light on this problem, we distinguished two types of expectancy violations-those that disconfirm and those that exceed one's expectancies-and we investigated whether awe is more likely to arise in reaction to one versus the other. We also looked at what appraisals constitute and are most important to the awe experience and how they structurally interact. To do this, we utilized network analysis and mapped out the network structure of appraisals linked to awe and to expectancy violations. Across two experimental studies (N = 823), we demonstrated that awe arises in reaction to exceeded (rather than disconfirmed) expectancies and that appraisals linked to exceeded expectancies (vastness and uniqueness) are central to awe, while appraisals linked to disconfirmed expectancies (uncertainty and inconsistency) are peripheral to the awe experience. Taken together, our investigation sheds new light on psychologists' understanding of expectancy violations and reveals when and how awe arises and what it entails.

RESUMO

Previous research on ADHD and ASD has mainly focused on the deficits associated with these conditions, but there is also evidence for strengths. Unfortunately, our understanding of potential strengths in neurodevelopmental conditions is limited. One particular strength, creativity, has been associated with both ADHD and ASD. However, the distinct presentations of both conditions beg the question whether ADHD and ASD associate with the same or different aspects of creativity. Therefore, the current study investigated the links between ADHD and ASD symptoms, creative thinking abilities, and creative achievements. To investigate the spectrum of ADHD and ASD symptoms, self-reported ADHD and ASD symptoms, convergent (Remote Associations Test) and divergent thinking (Alternative Uses Task) and creative achievements (Creative Achievement Questionnaire) were assessed in a self-reportedly healthy sample of adults (n = 470). We performed correlation analysis to investigate the relation between ADHD/ASD symptoms and creativity measures. In a second phase of analysis, data from an adult ADHD case-control study (n = 151) were added to investigate the association between ADHD symptoms and divergent thinking in individuals with and without a diagnosis of ADHD. Our analysis revealed that having more ADHD symptoms in the general population was associated with higher scores on all the outcome measures for divergent thinking (fluency, flexibility, and originality), but not for convergent thinking. Individuals with an ADHD diagnosis in the case-control sample also scored higher on measures of divergent thinking. Combining data of the population based and case-control studies showed that ADHD symptoms predict divergent thinking up to a certain level of symptoms. No significant associations were found between the total number of ASD symptoms and any of the creativity measures. However, explorative analyses showed interesting links between the ASD subdomains of problems with imagination and symptoms that relate to social difficulties. Our findings showed a link between ADHD symptoms and divergent thinking abilities that plateaus in the clinical spectrum of symptoms. For ASD symptoms, no relation was found with creativity measures. Increasing the knowledge about positive phenotypes associated with neurodevelopmental conditions and their symptom dimensions might aid psychoeducation, decrease stigmatization and improve quality of life of individuals living with such conditions.

RESUMO

Despite decades of extensive research on creativity, the field still combats psychometric problems when measuring individual differences in creative ability and people's potential to achieve real-world outcomes that are both original and useful. We think these seemingly technical issues have a conceptual origin. We therefore propose a minimal theory of creative ability (MTCA) to create a consistent conceptual theory to guide investigations of individual differences in creative ability. Building on robust theories and findings in creativity and individual differences research, our theory argues that creative ability, at a minimum, must include two facets: intelligence and expertise. So, the MTCA simply claims that whenever we do something creative, we use most of our cognitive abilities combined with relevant expertise to be creative. MTCA has important implications for creativity theory, measurement, and practice. However, the MTCA isn't necessarily true; it is a minimal theory. We discuss and reject several objections to the MTCA.

RESUMO

Attention deficit/hyperactivity disorder (ADHD) is a debilitating disorder and most research therefore focuses on its deficits and its treatment. Research on the potential positive sides of ADHD is limited, and although a comprehensive overview of empirical studies on this subject is missing, it has been suggested that ADHD is associated with enhanced creativity. To identify important relations, trends and gaps in the literature, we review 31 behavioral studies on creativity and ADHD, distinguishing different research designs, age groups, creativity measurements and effects of psychostimulants, as well as reflecting the potential underlying neural mechanisms of creativity and ADHD. Most studies find evidence for increased divergent thinking for those with high ADHD scores (subclinical) but not for those with the disorder (clinical). The rates of creative abilities/achievements were high among both clinical and subclinical groups. We found no evidence for increased convergent thinking abilities in ADHD, nor did we find an overall negative effect of psychostimulants on creativity. Neuroscientific findings suggest candidate regions as well as mechanisms that should be studied further to increase our understanding of the relationship between creativity and ADHD. We propose research opportunities to boost the knowledge needed to better understand the potential positive side of ADHD.

RESUMO

Objective: This research aimed to provide explanations for the inconsistent findings regarding creativity in ADHD. Method: In Study 1, we assessed real-world creative achievements and intrinsic motivation during idea generation in adults with ADHD and compared these with controls. In Study 2, we manipulated competition during idea generation to investigate effects on idea originality in adults with ADHD versus controls, and assessed creativity in specific domains. Results: Adults with ADHD reported more real-world creative achievements. We did not observe differences in intrinsic motivation during idea generation between groups, but adults with ADHD generated more original ideas when competing for a bonus. Moreover, adults with ADHD rated themselves as more creative in specific creative domains. Conclusion: Our findings suggest that goal-directed motivation may drive the enhanced real-world creative achievements of people with ADHD. Moreover, people with ADHD may selectively engage and excel in creative domains that fit their skills and preferences.

RESUMO

An increasing number of healthy people use methylphenidate, a psychostimulant that increases dopamine and noradrenaline transmission in the brain, to help them focus over extended periods of time. While methylphenidate has been shown to facilitate some cognitive functions, like focus and distractor-resistance, the same drug might also contribute to cognitive impairment, for example, in creativity. In this study, we investigated whether acute administration of a low oral dose (20 mg) of methylphenidate affected convergent and divergent creative processes in a sample of young healthy participants. Also, we explored whether such effects depended on individual differences in ADHD symptoms and working memory capacity. Contrary to our expectations, methylphenidate did not affect participants' creative performance on any of the tasks. Also, methylphenidate effects did not depend on individual differences in trait hyperactivity-impulsivity or baseline working memory capacity. Thus, although the effects of methylphenidate on creativity might be underestimated in our study due to several methodological factors, our findings do not suggest that methylphenidate impairs people's ability to be creative.

RESUMO

History is rife with examples of the dark side of creativity-ingenious weapons, novel torture practices, and creative terrorist attacks-yet its psychological origins are sparsely addressed and poorly understood. Building on work showing that social threat induces focused thinking as well as aggressive cognitions and readiness to fight, we propose that threats lead to more malevolent creativity and less creativity in threat-irrelevant domains. Prisoner's dilemma games were modified to evoke threat of exploitation. Participants then generated novel brick uses (Study 1, N = 113) or negotiation tactics (Study 2;N = 79). High (vs. low) social threat led to more "malevolent" creativity (e.g., using bricks as weapons; using intimidation as negotiation tactic). Social threat reduced nonthreat-related creative ideation only in Study 1. Study 2 showed that the increase of malevolent creativity was due to the motivation to defend and aggress, and emerged especially among individuals with a high need for cognition.

RESUMO

OBJECTIVE: Novelty seeking (the tendency to explore things novel and unfamiliar) has been extensively researched in the clinical and health domains, but its effects on creative performance are largely unknown. We examined whether creativity-related personality traits (openness to experience and extraversion) are associated with novelty seeking, and whether novelty seeking is linked to, and facilitates, creativity. METHOD: In Study 1a (N = 230; Mage = 20; 64% females) and Study 1b (N = 421; Mage = 19; 65% females), we measured extraversion, openness to experience, novelty seeking, and divergent thinking. To provide causal evidence for the relation between novelty seeking and creativity, in Study 2 (N = 147; Mage = 27; 75% females), we manipulated people's motivation to seek novelty and then measured subsequent divergent thinking. RESULTS: In Studies 1a and 1b, we demonstrated that trait novelty seeking is associated with openness and extraversion, on the one hand, and divergent thinking on the other. In Study 2, the novelty seeking manipulation led to greater divergent thinking. CONCLUSIONS: We conclude that novelty seeking is linked to openness to experience and extraversion, and that it can lead to greater divergent thinking.

RESUMO

Critical to creative cognition and performance is both the generation of multiple alternative solutions in response to open-ended problems (divergent thinking) and a series of cognitive operations that converges on the correct or best possible answer (convergent thinking). Although the neural underpinnings of divergent and convergent thinking are still poorly understood, several electroencephalography (EEG) studies point to differences in alpha-band oscillations between these thinking modes. We reason that, because most previous studies employed typical block designs, these pioneering findings may mainly reflect the more sustained aspects of creative processes that extend over longer time periods, and that still much is unknown about the faster-acting neural mechanisms that dissociate divergent from convergent thinking during idea generation. To this end, we developed a new event-related paradigm, in which we measured participants' tendency to implicitly follow a rule set by examples, versus breaking that rule, during the generation of novel names for specific categories (e.g., pasta, planets). This approach allowed us to compare the oscillatory dynamics of rule convergent and rule divergent idea generation and at the same time enabled us to measure spontaneous switching between these thinking modes on a trial-to-trial basis. We found that, relative to more systematic, rule convergent thinking, rule divergent thinking was associated with widespread decreases in delta band activity. Therefore, this study contributes to advancing our understanding of the neural underpinnings of creativity by addressing some methodological challenges that neuroscientific creativity research faces.

RESUMO

Creative cognition is key to human functioning yet the underlying neurobiological mechanisms are sparsely addressed and poorly understood. Here we address the possibility that creative cognition is a function of dopaminergic modulation in fronto-striatal brain circuitries. It is proposed that (i) creative cognition benefits from both flexible and persistent processing, (ii) striatal dopamine and the integrity of the nigrostriatal dopaminergic pathway is associated with flexible processing, while (iii) prefrontal dopamine and the integrity of the mesocortical dopaminergic pathway is associated with persistent processing. We examine this possibility in light of studies linking creative ideation, divergent thinking, and creative problem-solving to polymorphisms in dopamine receptor genes, indirect markers and manipulations of the dopaminergic system, and clinical populations with dysregulated dopaminergic activity. Combined, studies suggest a functional differentiation between striatal and prefrontal dopamine: moderate (but not low or high) levels of striatal dopamine benefit creative cognition by facilitating flexible processes, and moderate (but not low or high) levels of prefrontal dopamine enable persistence-driven creativity.

RESUMO

Although many believe that creativity associates with a vulnerability to psychopathology, research findings are inconsistent. Here we address this possible linkage between risk of psychopathology and creativity in nonclinical samples. We propose that propensity for specific psychopathologies can be linked to basic motivational approach and avoidance systems, and that approach and avoidance motivation differentially influences creativity. Based on this reasoning, we predict that propensity for approach-based psychopathologies (e.g., positive schizotypy and risk of bipolar disorder) associates with increased creativity, whereas propensity for avoidance-based psychopathologies (e.g., anxiety, negative schizotypy, and depressive mood) associates with reduced creativity. Previous meta-analyses resonate with this proposition and showed small positive relations between positive schizotypy and creativity and small negative relations between negative schizotypy and creativity and between anxiety and creativity. To this we add new meta-analytic findings showing that risk of bipolar disorder (e.g., hypomania, mania) positively associates with creativity (k = 28, r = .224), whereas depressive mood negatively associates (albeit weakly) with creativity (k = 39, r = -.064). Our theoretical framework, along with the meta-analytic results, indicates when and why specific psychopathologies, and their inclinations, associate with increased or, instead, reduced creativity.

RESUMO

Narcissistic individuals have highly positive self-views and overestimate their abilities. Consequently, they tend to react aggressively whenever they receive information that does not match their high self-views (ego threat). We argue that focusing on aggression merely portrays a one-sided view of narcissistic individuals and the manner in which they counter ego threats. We propose that following ego threat, narcissism can also fuel performance. In four studies, we measured nonclinical narcissism and allocated Dutch undergraduate university students (N1 = 175, N2 = 142, N3 = 159, N4 = 174) to either an ego threat or a no ego threat condition. Ego threat involved negative feedback (Studies 1-2) or threat to uniqueness (Studies 3-4). We measured participants' intentions to complete a challenging task (Study 1), their creative performance (Studies 2-3), and their performance on an anagram task (Study 4). Across Studies 1-3, we consistently found that following ego threat, higher nonclinical narcissism was associated with greater willingness to perform tasks that enabled demonstration of abilities and enhanced creative performance. These results were confirmed using a meta-analysis. However, anagram performance was not enhanced following ego threat. We provide additional analyses that might help explain this. Our findings thus reveal a more positive side to the way narcissistic individuals manage threats to their self-image.

RESUMO

Meditation is becoming an increasingly popular topic for scientific research and various effects of extensive meditation practice (ranging from weeks to several years) on cognitive processes have been demonstrated. Here we show that extensive practice may not be necessary to achieve those effects. Healthy adult non-meditators underwent a brief single session of either focused attention meditation (FAM), which is assumed to increase top-down control, or open monitoring meditation (OMM), which is assumed to weaken top-down control, before performing an Attentional Blink (AB) task - which assesses the efficiency of allocating attention over time. The size of the AB was considerably smaller after OMM than after FAM, which suggests that engaging in meditation immediately creates a cognitive-control state that has a specific impact on how people allocate their attention over time.

RESUMO

Oxytocin is an evolutionary ancient hypothalamic neuropeptide well known for its role in reproduction, social bonding, and group affiliation. Recent work has linked oxytocin in humans to creative cognition--the ability to produce insights, ideas, and problem solutions that are original and potentially useful. Here we review this literature, focusing on the relationship between (1) single-nucleotide polymorphisms in the oxytocin receptor (OXTR) gene; endogenous oxytocin from blood plasma, and intranasal administration of oxytocin (vs placebo), and (2) creativity-related traits (e.g., novelty seeking, extraversion, and openness to experience), and behaviors (e.g., exploration, divergent thinking, original ideation, and problem solving). Findings are interpreted in the context of the dual pathway to creativity model and except for OXTR: (1) reveal a weak to moderate but consistent association between oxytocin and creativity, which emerges because (2) oxytocin enables the cognitive flexibility pathway more than persistent information processing. Findings can be best understood in terms of oxytocin's putative effects on dopaminergic activity and concomitant approach tendency.

RESUMO

Past work has linked mindfulness to improved emotion regulation, interpersonal skills, and basic cognitive abilities, but is unclear about the relation between mindfulness and creativity. Studies examining effects of mindfulness on factors pertinent to creativity suggest a uniform and positive relation, whereas work on specific mindfulness skills suggests that mindfulness skills may differentially predict creativity. To test whether the relation between mindfulness and creativity is positive and uniform (the uniform hypothesis) or differentially depends on particular components of mindfulness (the differential hypothesis), we conducted four studies in which mindfulness skills were measured, extensively trained, or manipulated with a short, incidental meditation session. Results supported a differential relation between mindfulness and creativity: Only the ability to observe and attend to various stimuli consistently and positively predicted creativity. Results regarding other mindfulness skills were less consistent. Implications for theory and practice are discussed.
