Unity and diversity of executive functions in creativity

Increasing evidence suggests that executive functions (EFs) – a set of general-purpose control processes that regulate thoughts and behaviors – are relevant for creativity. However, EF is not a unitary process, and it remains unclear which specific EFs are involved. The present study examined the association between the three EFs, both uniquely (EF-Specific) and together (Common EF), and three measures of creativity. Participants (N = 47) completed a divergent thinking test, and self-reported their real-life creative accomplishments. A subset of participants indicated their involvement in the artistic or information technology (IT) professions. Results indicated that fluency (but not originality) of divergent thinking was uniquely predicted by working memory Updating. Better response Inhibition predicted higher number of real-world artistic creative achievements. Involvement in the artistic (versus IT) professions was associated with better Common EF, and with enhanced mental set Shifting abilities. Results demonstrate that different EFs predict creativity depending on its operational definition.     

The role of schizotypy and creativity in a group problem-solving task

The well-studied link between psychotic traits and creativity is a subject of much debate. The present study investigated the extent to which schizotypic personality traits – as measured by O-LIFE (Oxford–Liverpool Inventory of Feelings and Experiences) – equip healthy individuals to engage as groups in everyday tasks. From a sample of 69 students, eight groups of four participants – comprised of high, medium, or low-schizotypy individuals – were assembled to work as a team to complete a creative problem-solving task. Predictably, high scorers on the O-LIFE formulated a greater number of strategies to solve the task, indicative of creative divergent thinking. However, for task success (as measured by time taken to complete the problem) an inverted U shaped pattern emerged, whereby high and low-schizotypy groups were consistently faster than medium schizotypy groups. Intriguing data emerged concerning leadership within the groups, and other tangential findings relating to anxiety, competition and motivation were explored. These findings challenge the traditional cliché that psychotic personality traits are linearly related to creative performance, and suggest that the nature of the problem determines which thinking styles are optimally equipped to solve it.     

Creativity on tap 2: Investigating dose effects of alcohol on cognitive control and creative cognition

This preregistered study aimed to replicate and extend research on the role of cognitive control in creative cognition by examining dose effects of alcohol in a randomized controlled trial. A sample of 125 participants was randomly assigned to three experimental groups, either drinking alcoholic beer (BAC = 0.03 or 0.06) or drinking non-alcoholic beer (placebo-control group). Before and after the alcohol intervention, participants completed two tests of cognitive control and two established creative thinking tasks. A BAC of 0.06 led to an impairment of verbal fluency, while working memory performance was unaffected at both alcohol levels. Alcohol had no facilitative or detrimental effects on creative thinking performance, neither in terms of RAT performance, divergent thinking fluency or divergent thinking creativity. These results indicate that moderate alcohol levels have dose-dependent, selective effects on cognitive control, and that minor impairments of cognitive control do not generally increase or attenuate creative thinking performance.     

Neuropsychological Functioning in Children with Posttraumatic Stress Disorder

Posttraumatic stress disorder (PTSD) has been associated with deficits in the areas of verbal memory and learning, executive functioning, working memory, and attention in adults. Findings have been less consistent in the few studies examining neuropsychological functioning in childhood PTSD, which are often limited by comparing children with PTSD to children without trauma histories, making it unclear whether observed neuropsychological deficits are related to trauma exposure or to PTSD symptomatology. In an ethnically diverse sample of 62 children who witnessed intimate partner violence (n = 27 PTSD+ and 35 PTSD?), children with PTSD exhibited slower and less effective learning, heightened sensitivity to interference, and impaired effect of rehearsal on memory acquisition on the California Verbal Learning Test – Children's Version, a word list learning task. Both groups performed in the below average range on measures of executive functioning, attention, and intellectual ability.     

Dimensions of religious/spiritual well-being and schizotypal personality

Dimensions of religious/spiritual well being (RSWB; such as hope, forgiveness, or general religiosity) have been examined comprehensively, and its positive relation to subjective well-being has been confirmed. However, there also might be facets of RSWB linked to mental illness (e.g. delusional ideas). The aim of the present study was to investigate the association between different dimensions of RSWB, magical thinking as an indicator of schizotypy and Eysenck´s three personality factors (psychoticism, extraversion, neuroticism), as there might be facets of RSWB also linked to mental illness (e.g. delusional ideas). One hundred and two undergraduate students (53 female, 49 male) completed the Multidimensional Inventory of Religious/Spiritual Well-Being (MI-RSWB), the Eysenck Personality Questionnaire in short version (EPQ-RK) together with the Magical Ideation Scale. Results indicate that facets of RSWB based on magical thinking could also be understood as neurotic symptoms. This underlines the hypothesis, that there might be pathogenetic as well as salutogenetic aspects of religiosity/spirituality associated with personality and subjective well-being.     

Schizotypy and affective temperament: Relationships with divergent thinking and creativity styles

Schizotypy and affective temperament have both been linked to creativity using measures such as divergent thinking (DT) but not in terms of creativity styles. The relationship between schizotypy and affective temperament has also not been examined directly in a creativity paradigm. Seventy-eight (44 female, 34 male) university students completed two DT tasks and measures of schizotypy, affective temperament, and creativity styles. Positive schizotypy was correlated with creativity styles, and affective temperament was correlated with both creativity styles and DT scores. Furthermore, schizotypy and affective temperament differentially predicted DT scores and creativity styles. Finally, the relationship between schizotypy and affective temperament gave evidence towards a unitary psychosis theory. Results are discussed in terms of current theories about psychosis and psychoticism and their association to creativity.     

Creativity on tap? Effects of alcohol intoxication on creative cognition

Anecdotal reports link alcohol intoxication to creativity, while cognitive research highlights the crucial role of cognitive control for creative thought. This study examined the effects of mild alcohol intoxication on creative cognition in a placebo-controlled design. Participants completed executive and creative cognition tasks before and after consuming either alcoholic beer (BAC of 0.03) or non-alcoholic beer (placebo). Alcohol impaired executive control, but improved performance in the Remote Associates Test, and did not affect divergent thinking ability. The findings indicate that certain aspects of creative cognition benefit from mild attenuations of cognitive control, and contribute to the growing evidence that higher cognitive control is not always associated with better cognitive performance.     

Neuropsychological functioning in kleptomania

Kleptomania is characterized by the failure to resist impulses to steal objects not needed for personal use or their monetary value. The objective of this study was to examine cognitive and executive functioning in subjects with kleptomania. Fifteen women with a primary DSM-IV diagnosis of kleptomania underwent a detailed psychiatric examination, including measures of kleptomania severity, and a battery of neuropsychological tests that emphasized executive functions. Correlational analyses were computed between measures of kleptomania severity and tests of executive functioning. Kleptomania subjects reported a mean duration of illness of 17.9 years and shoplifting a mean of 1.7 times per week. All subjects reported an inability to resist urges to shoplift. Neuropsychological testing revealed group mean test scores within 0.5 standard deviations of normative standards for age. Five subjects (33.3%), however, had below-average performance on at least one measure of executive functioning, and 4 (26.7%) had below-average scores on two executive measures. Correlational analyses revealed a statistically significant correlation between kleptomania severity and Wisconsin Card Sorting Test performance (r=-0.693, p=0.004). As a group, subjects with kleptomania did not demonstrate deficits on neuropsychological testing. Greater kleptomania symptom severity, however, was correlated with impairment in executive functioning.     

Personality and intelligence as predictors of creativity

Participants completed the Big Five NEO-FFI (Costa & McCrae, 1992) as a personality measure, the Wonderlic Personnel Test (Wonderlic, 1992) as an intelligence measure, and four measures of creativity: Guilford’s (1967) unusual uses divergent thinking test; the Biographical Inventory of Creative Behaviours; a self-rated measure of creativity; and the Barron–Welsh Art Scale to measure creative judgement. Extraversion was significantly related to all four measures of creativity. Intelligence failed to add any incremental variance in predicting the creativity scores. Multiple regression indicated that up to 47% of the variance in divergent thinking scores can be accounted for by the Big Five personality traits. Personality correlates to creativity vary as a function of the creativity measure.     

The Early Neuropsychological and Behavioral Characteristics of Frontotemporal Dementia

Frontotemporal lobar degeneration (FTLD) represent a constellation of disorders that may be overlooked or misdiagnosed, despite being fairly common presenile neurodegenerative diseases. Although the cognitive disorder can be difficult to document, particularly early in the dementia course, neuropsychological evaluation can assist in the diagnosis. Neuropsychologists are in an excellent position to draw from related disciplines like personality theory and social psychology to better assess the types of changes that characterize the prodromal and early phases of the disease. This review summarizes the current state of the field in the diagnosis of FTLD and discusses the emerging role of neuropsychology in elucidating the brain organization of complex processes including empathy, behavioral control and inhibition, reward systems, appetitive behaviors, emotional regulation, and goal-orientation. As this review underscores, frontotemporal dementia remains a powerful model for studying brain–behavior relationships.     

Quadrupedal movement training improves markers of cognition and joint repositioning

IntroductionExercise, and in particular balance and coordination related activities such as dance, appear to have positive effects on cognitive function, as well as neurodegenerative conditions such as dementia and Parkinson’s disease. Quadrupedal gait training is a movement system requiring coordination of all four limbs that has previously been associated with cognitive development in children. There is currently little research into the effect of complex QDP movements on cognitive function in adults.PurposeTo determine the effects of a novel four-week quadrupedal gait training programme on markers of cognitive function and joint reposition sense in healthy adults.MethodsTwenty-two physically active sports science students (15 male and 7 female) were divided into two groups: a training group (TG) and a control group (CG). All participants completed the Wisconsin Card Sorting Task (WCST) and were tested for joint reposition sense before and after a four-week intervention, during which time the TG completed a series of progressive and challenging quadrupedal movement training sessions.ResultsParticipants in the TG showed significant improvements in the WCST, with improvements in perseverative errors, non-perseverative errors, and conceptual level response. This improvement was not found in the CG. Joint reposition sense also improved for the TG, but only at 20 degrees of shoulder flexion.ConclusionsPerformance of a novel, progressive, and challenging task, requiring the coordination of all 4 limbs, has a beneficial impact on cognitive flexibility, and in joint reposition sense, although only at the specific joint angle directly targeted by the training. The findings are consistent with other studies showing improvements in executive function and joint reposition sense following physical activity.     

When knowledge is not enough: the phenomenon of goal neglect in preschool children

We argue that the concept of goal neglect can be fruitfully applied to understand children's potential problems in experimental tasks and real-world settings. We describe an assessment of goal neglect developed for administration to preschool children and report data on two measures derived from this task alongside the Dimensional Change Card Sort (DCCS) and an opposite color response inhibition task. The propensity to neglect initial task cues was uniquely linked to response inhibition, whereas neglect of a later cue was uniquely linked to the DCCS. Additional evidence suggests that recovery from neglect can occur and shows that goal neglect varies with the cognitive transparency of the signifying cue. Data demonstrate the importance of, and place constraints on, current theories of information regulation and foreground the notion of graded representations in working memory and executive functioning.     

Executive functioning and processing speed in age-related differences in memory: Contribution of a coding task

The aim of the present study was to examine executive dysfunctioning and decreased processing speed as potential mediators of age-related differences in episodic memory. We compared the performances of young and elderly adults in a free-recall task. Participants were also given tests to measure executive functions and perceptual processing speed and a coding task (the Digit Symbol Substitution Test, DSST). More precisely, we tested the hypothesis that executive functions would mediate the age-related differences observed in the free-recall task better than perceptual speed. We also tested the assumption that a coding task, assumed to involve both executive processes and perceptual speed, would be the best mediator of age-related differences in memory. Findings first confirmed that the DSST combines executive processes and perceptual speed. Secondly, they showed that executive functions are a significant mediator of age-related differences in memory, and that DSST performance is the best predictor.     

The paradox of creativity

Creativity seems to yield survival and reproductive benefits. Creative behaviors allow individuals to solve problems in new and appropriate ways, and thus to promote their survival. They also facilitate bonding and constitute a signal of one's fitness, favoring attraction of mates. However, to be creative, individuals often have to violate social norms in order to promote change. So far, this deviance induced by creative behaviors had not been seen as an adaptive disadvantage. This deviance entails negative consequences as social exclusion or ostracism, which are detrimental for both survival (e.g., reduced access to resources within the group) and reproduction (reduced reproductive fitness). Thus, the adaptive benefits yielded by creativity have to be nuanced by these potential disadvantages. The paradox of creativity proposes a finer-grained vision of the adaptive reasons why creativity has been maintained within the human species, has evolved, and is collectively regulated. Research perspectives are also proposed.     

基于语义网络的创造性认知机制研究现状与展望

语义网络是主要的知识表征方式之一,对创造性研究具有重要意义。近年来不断发展的网络科学方法为相关研究提供了强大的方法论框架及量化工具,研究者得以分别从语义网络结构及语义相关认知操作的角度探讨语义网络与创造性的内在联系。已有证据表明语义网络中所储存的概念越丰富、概念间的连接通路越多元化或越灵活,则个体创造性水平越高;而个体创造性水平亦受制于个体对概念的检索、抑制、选择、整合及扩展等认知能力。在此方向上,未来研究工作应当更多地思考如何在一个相对整合的认知框架中深入探讨语义网络结构及相关认知过程对创造性的交互作用,并结合神经影像等技术手段,将语义网络之于创造性的认知机制嵌套于神经科学体系中进行解释。     

An “alternating instructions” version of the Autobiographical Memory Test for assessing autobiographical memory specificity in non-clinical populations

There is limited research regarding how executive processes contribute to key cognitive deficits in depression, particularly impoverished retrieval of autobiographical memory. This study tested a novel version of the Autobiographical Memory Test (AMT), the “Alternating Instructions” AMT (AMT-AI), to determine how participants could flexibly retrieve specific and categoric autobiographical memories. The AMT-AI consisted of a standard AMT (AMT-S), a categoric version of the AMT (AMT-R), and a section of alternating instructions (AI) in which the rules required the participant to alternate between retrieval of categoric and specific memories. A total of 49 university students completed the AMT-AI, and self-report measures of depressive symptomatology and ruminative thinking. Results showed that the mean proportion of specific memories recalled on the AMT-AI was significantly lower than on the AMT-S. Also, reduced memory specificity on the AMT-AI, but not the AMT-S, was significantly negatively correlated with increased scores on measures of depressive symptomatology and ruminative thinking. Collectively the data suggested that the AMT-AI, relative to the traditional AMT, may be more sensitive to memory specificity in non-clinical populations. Future research is warranted to further determine the psychometric properties and utility of the AMT-AI.     

Dimensional schizotypy,autism, and unusual word associations in artists and scientists

Studies from a range of perspectives provide evidence for a relationship between creativity and the tendency to mental illness. The present study further examined this issue by administering questionnaires measuring the minor features of psychosis and autism to 31 professional “artists” (visual artists and musicians) and 28 professional “scientists” (biological scientists and physical scientists/mathematicians). The Oxford–Liverpool Inventory of Feelings and Experiences (O–LIFE), the Hypomanic Personality Scale, and the Autism-Spectrum Quotient (AQ), were administered, in addition to a shortened form of the Kent–Rosanoff Word Association Scale. The results provided strong support for the connection of artistic creativity to positive schizotypy and hypomania and the tendency to make unusual word associations, and somewhat weaker support for the connection of scientific creativity to certain components of the autism spectrum.     

Schizotypy and mental health amongst poets, visual artists, and mathematicians

Many researchers have found evidence of an association between creativity and the predisposition to mental illness. However, a number of questions remain unanswered. First, it is not clear whether healthy creatives have a milder loading on schizotypal traits than people who suffer serious psychopathology, or whether they have an equal loading, but other mediating characteristics. Second, most of the existing research has concentrated on artistic creativity, and the position of other creative domains is not yet clear. The present study compares schizotypy profiles using the O-LIFE inventory in a large sample of poets, artists, mathematicians, the general population, and psychiatric patients. Poets and artists have levels of unusual experiences that are higher than controls, and as high as schizophrenia patients. However, they are relatively low on the dimension of introvertive anhedonia. Mathematicians are lower than controls on unusual experiences. The results suggest that artistic creatives and psychiatric patients share a tendency to unusual ideas and experiences, but creative groups are distinguished by the absence of anhedonia and avolition. Moreover, different domains of creativity require different cognitive profiles, with poetry and art associated with divergent thinking, schizophrenia and affective disorder, and mathematics associated with convergent thinking and autism.     

Androgyny and creativity: a study of the relationship between a balanced sex-role and creative functioning

The relationship between creativity and androgyny was studied in 163 women and men with the Creative Functioning Test (CFT) and the Bem Sex Role Inventory (BSRI). A 2 (femininity: high/low) x 2 (masculinity: high/low) x 2 (sex) ANOVA was conducted on subjects' CFT scores. A significant interaction effect between femininity and masculinity was found showing that subjects high on both femininity and masculinity (androgynous) and low on both scales (undifferentiated) reached higher CFT scores than female-typed and male-typed subjects. Further, a significant three-way interaction including sex of subject indicated that the former two-way interaction was accounted for by men only.     

Understanding the relationship between mood and creativity: A meta-analysis

A meta-analysis of 62 experimental and 10 non-experimental studies was conducted to evaluate the positive-mood-enhances-creativity generalization. While the results demonstrate that positive mood enhances creativity, the strength of that effect is contingent upon the comparative or referent mood state (i.e., neutral or negative mood) as well as the type of creative task. Further, the pattern of effect sizes supports a curvilinear relationship between affective intensity and creative performance. In general, a contextual perspective of mood–creativity relations is supported.
