Elements of creative thought: Investigating the cognitive and neural correlates of association and bi-association processes.

Creative thinking relies on the ability to make remote associations and fruitfully combine unrelated concepts. Hence, original associations and bi-associations (i.e., associations to one and two concepts, respectively) are considered elementary cognitive processes of creative cognition. In this work, we investigated the cognitive and brain mechanisms underlying these association processes with tasks that asked for original associations to either one or two adjective stimuli. Study 1 showed that the generation of more original associations and bi-associations was related to several indicators of creativity, corroborating the validity of these association performances as basic processes underlying creative cognition. Study 2 assessed brain activity during performance of these association tasks by means of fMRI. The generation of original versus common associations was related to higher activation in bilateral lingual gyri suggesting that cued search for remote representatives of given properties are supported by visually-mediated search strategies. Parametric analyses further showed that the generation of more original associations involved activation of the left inferior frontal cortex and the left ventromedial prefrontal cortex, which are consistently implicated in constrained retrieval and evaluation processes, and relevant for making distant semantic connections. Finally, the generation of original bi-associations involved higher activation in bilateral hippocampus and inferior parietal lobe, indicating that conceptual combination recruits episodic simulation processes. Together, these findings suggest that the generation of verbally cued, original associations relies not only on verbal semantic memory but involves mental imagery and episodic simulation, offering new insights in the nuanced interplay of memory systems in creative thought.

Functional coupling of brain networks during creative idea generation and elaboration in the figural domain.

The neuroscientific investigation of creative cognition has advanced by considering the functional connectivity between brain regions and its dynamic changes over time, which are consistent with stages in the ideation process. Surprisingly, although the communication between neuronal networks takes place in a time-scale of milliseconds, EEG studies investigating a time-course in cortico-cortical communication during creative ideation are rare and findings are typically restricted to the verbal domain. Therefore, this study examined functional coupling using EEG (task-related phase-locking in the upper-alpha range) during creative thinking in the figural domain. Using an innovative computerized experimental paradigm, we specifically investigated the stage of idea generation and the stage of idea elaboration in an adapted picture completion task. The findings confirmed a hypothesized increase of functional coupling from idea generation to elaboration, which was most pronounced in frontal-central as well as frontal-temporal networks. The connectivity in the frontal-parietal/occipital network already increased during idea generation and remained constant during elaboration. Importantly, more original participants generally showed higher functional connectivity in all brain networks. This elevated functional coupling with frontal brain regions might reflect increased executive processes related to internal attention, motor planning, and semantic selection processes supporting highly original thought in the figural domain.

Effects of an adjunctive, chronotype-based light therapy in hospitalized patients with severe burnout symptoms - a pilot study.

Light therapy is a well-established treatment option for seasonal affective disorders and is effective in reducing sleep problems and daytime fatigue. Symptoms of severe burnout include feelings of exhaustion and impaired sleep and mood. Thus, light therapy seems promising for burnout treatment. So far, light therapy effects in burnout were investigated in outpatient settings only, with inconclusive results. The present study targeted light therapy effects in an inpatient setting. Participants with severe burnout were recruited in two psychosomatic clinics and randomly assigned to a control group with multimodal psychiatric treatment or an add-on light treatment group. Participants in the latter group were additionally exposed to morning bright light (illuminance: 4246 lux, irradiance: 1802.81 µW.cm-2) for 3 weeks, 30 minutes a day, timed to their chronotypes. Light effects on burnout symptoms, depression, well-being, daytime sleepiness, sleep quality, and attentional performance were measured twice (pre-/postintervention design). Adjunctive chronotype-based bright light therapy was well tolerated and improved burnout symptoms and well-being without additional effect on severity of depression. Furthermore, reduced daytime sleepiness, improved nighttime sleep quality, a sleep phase advance of 25 minutes, shortened sleep latency, less sleep disturbances and increased sleep duration were observed in the light treatment group. No group differences were found in attentional performance. Chronotype-based bright light therapy seems to be effective in improving burnout symptoms and sleep problems in patients with severe burnout symptoms. Further studies with larger sample sizes and objective measures of sleep are necessary to confirm these preliminary results before practical recommendations can be made.

EEG alpha activity during imagining creative moves in soccer decision-making situations.

This study investigated task-related changes of EEG alpha power while participants were imagining creative moves in soccer decision-making situations. After presenting brief video clips of a soccer scene, participants had to imagine themselves as the acting player and to think either of a creative/original or an obvious/conventional move (control condition) that might lead to a goal. Performance of the soccer task generally elicited comparatively strong alpha power decreases at parietal and occipital sites, indicating high visuospatial processing demands. This power decrease was less pronounced in the creative vs. control condition, reflecting a more internally oriented state of information processing characterized by more imaginative mental simulation rather than stimulus-driven bottom-up processing. In addition, more creative task performance in the soccer task was associated with stronger alpha desynchronization at left cortical sites, most prominently over motor related areas. This finding suggests that individuals who generated more creative moves were more intensively engaged in processes related to movement imagery. Unlike the domain-specific creativity measure, individual's trait creative potential, as assessed by a psychometric creativity test, was globally positively associated with alpha power at all cortical sites. In investigating creative processes implicated in complex creative behavior involving more ecologically valid demands, this study showed that thinking creatively in soccer decision-making situations recruits specific brain networks supporting processes related to visuospatial attention and movement imagery, while the relative increase in alpha power in more creative conditions and in individuals with higher creative potential might reflect a pattern relevant across different creativity domains.

The creative brain in the figural domain: Distinct patterns of EEG alpha power during idea generation and idea elaboration.

This study investigated EEG activity in the upper alpha band during the well-known Picture Completion Task of the Torrance Test of Creative Thinking (TTCT), a widely used creative ideation task in the figural domain. The application of a sophisticated computerized version of the TTCT facilitating the online assessment and digitalizing of participant's drawings allowed to separate two central stages of the creative ideation process (i.e., idea generation and idea elaboration). During idea generation, the participants' task was to generate an initial draft of an original and creative completion of the presented abstract lines and figures of the TTCT. During idea elaboration, the participants were required to mentally improve the originality of the initially generated idea/draft. Creative ideation in this figural task was generally associated with comparatively strong desynchronization of upper alpha power over parietal and occipital sites, indicating high visual/figural processing demands. Interestingly, the stage of idea elaboration was accompanied by a relative increase of upper alpha power at parietal and occipital sites compared to the stage of idea generation, indicating heightened top-down processing demands. Furthermore, task performance was associated with relative increases of upper alpha power at frontal sites and relative decreases at centro-temporal sites from the stage of idea generation to idea elaboration. This association suggests the importance of increased inhibitory control over stimulus-based bottom-up information and motor imagery in order to achieve more creative outputs. Taken together these findings add to the relevant literature in that they a) extend research on the relationship between EEG alpha activity and creativity to the figural domain, and b) support a multistage view of creative ideation, involving cognitive control and mental imagery as important components of creativity.

Facets of Spirituality Diminish the Positive Relationship between Insecure Attachment and Mood Pathology in Young Adults.

Traditionally, in attachment theory, secure attachment has been linked to parameters of mental health, while insecure attachment has been associated with parameters of psychopathology. Furthermore, spirituality and attachment to God have been discussed as corresponding to, or compensating for, primary attachment experiences. Accordingly, they may contribute to mental health or to mental illness. In this cross-sectional observational study, we investigate attachment styles (Avoidant and Anxious Attachment; ECR-RD), spirituality (Religious and Existential Well-Being; MI-RSWB), and mood pathology (Anxiety, Depression, Somatization; BSI-18) in 481 (76% female) young adults (age range: 18-30 years) who had a Roman Catholic upbringing. In accordance with previous research, we found insecure attachment to be associated with low levels of spirituality. Furthermore, insecure attachment and low levels of spirituality were associated with higher levels of mood pathology. In hierarchical regression analyses, only Anxious Attachment positively predicted all three dimensions of mood pathology while Existential Well-Being-but not Religious Well-Being-was an additional negative predictor for Depression. Our results underline that spirituality can correspond to the attachment style, or may also compensate for insecure attachment. Higher Existential Well-Being-comprised of facets such as hope for a better future, forgiveness and the experience of sense and meaning-seems to have an especially corrective effect on mood pathology, independent of attachment styles. Our findings emphasize the vital role of existential well-being in young adults' affective functioning, which might be considered in prevention and treatment. Further research in clinical surroundings is recommended.

Vulnerable Dark Triad Personality Facets Are Associated with Religious Fundamentalist Tendencies.

BACKGROUND: This study explores the possibility that religious fundamentalism (RF) may be linked to deficits in personality structure, which is in contrast to the general assumption that religiosity and spirituality are positively related to mature personality development. SAMPLING AND METHODS: To test this hypothesis, 327 (232 female) college students completed the Multidimensional Inventory for Religious/Spiritual Well-Being together with the Innsbrucker Religious Fundamentalism Scale. In addition, the 'vulnerable dark triad' of personality ('vulnerable narcissism', subscale of the Pathological Narcissism Inventory; 'secondary psychopathy', subscale of Levenson's Self-Report Psychopathy Scale; 'borderline personality', of the Borderline Personality Inventory) was assessed. RESULTS: In general, the relation between spirituality and healthy personality functioning was confirmed. In addition to greatly overlapping with 'general religiosity' (p < 0.001), RF was also relevantly predicted by narcissistic ('hiding the self') and borderline ('primitive defenses') personality facets (p < 0.05 for both). CONCLUSIONS: Based on these preliminary data, we conclude that specific structural deficits in personality might lead to more rigorous variants of religious/spiritual beliefs such as RF. Further research in clinical surroundings as well as in religious extremist groups is recommended.

The Validation of a Spanish Version of the Multidimensional Inventory of Religious/Spiritual Well-Being in Mexican College Students.

After the Multidimensional Inventory for Religious/Spiritual Well-Being (MI-RSWB) was validated as a reliable instrument for the Western European context it is primarily intended in this study to translate the measure into Spanish and adapt it for the Mexican culture. Furthermore we investigate whether spirituality/religiosity has a similar impact on indicators of personality and subjective well-being in Mexico as it does in samples drawn from Western European cultures. 190 students (99 females) from public and private universities in Guadalajara, all Mexican citizens, were involved in this study. We found strong evidential support for the six factor solution of the Original MI-RSWB in this Mexican population. By mirroring previous research the measure showed a highly satisfying internal consistency (α = .91 for the total score and .75 or higher for all six sub dimensions). Furthermore the total RSWB score was observed to be related with Eysenck's personality dimensions Extraversion (r = .24, p < .01), and Psychoticism (r = -.28, p < .001), although not with Neuroticism. There was also a positive correlation with Sense of Coherence (r = .31, p < .001). In conclusion, the dimensionality of RSWB and its associations with personality and subjective well-being was well supported in this first application within a Mexican cultural context.

[The relationship between Yoga Immersion, psychological well-being and psychiatric symptoms]. / Die Beziehung zwischen Yoga Immersion, psychologischem Wohlbefinden und psychiatrischer Symptomatik.

BACKGROUND: In recent years positive effects of Yoga (as a kind of spiritual exercise) in regards to subjective well-being and physical health can be found as well documented in the literature. METHOD: Based on a construct-psychological approach a newly developed scale for the assessment of Yoga involvement (immersion) was validated on a sample of 233 non-clinical subjects (210 females) by means of socio-demographic and well established psychometric parameters of psychological well-being and psychiatric symptoms. Furthermore, the group of yoga practitioners was compared with a control group consisting of 93 gymnastics practitioners (83 women) with respect to these parameters. RESULTS: The amount of Yoga Immersion (YI) can be reliably assessed by means of the one-dimensional YI-scale (10 items) and shows to be strongly correlated with Mindfulness (r = .56; p < .01), Inner Correspondence (r = .61; p < .01) and Religious/Spiritual Well-being (r = .68; p < .01). Furthermore highly yoga-immersive practitioners exhibited a significant higher amount of psychological well-being (p < .01) compared to marginally/moderately yoga-immersive and gymnastics practitioners. The Yoga-group also showed a lower amount of psychiatric symptoms (e.g. depression; p < .01). CONCLUSIONS: The globally postulated positive relationship between Yoga-practicing and mental health could be confirmed; thereby the impact of YI can be assumed as central. Further randomized controlled trial research focusing on the health/disease-related aspects of YI might be conducted especially in clinical groups.

[Religious/spiritual well-being in mentally ill persons III: first results of a body-centered awareness meditation for in-patient rehabilitation]. / Religiös/Spirituelles Befinden bei psychisch Kranken III: Erste Ergebnisse einer Körper-zentrierten Achtsamkeitsmeditation in der stationären Rehabilitation.

OBJECTIVE: In recent years, positive effects of religiosity and spirituality on mental health can be found as well documented in the literature. However, very few studies have examined the effects of a spiritually based therapeutic intervention among psychiatric patients. METHOD: For this reason, in this pilot study we examined the effectiveness of a morning body-centered meditation in comparison to a conventional morning walk in regards to subjective well-being and stress coping styles in 44 (26 females) randomly assigned psychiatric in-patients (according to ICD 10). The patients' amount of subjective well-being as well as their coping ability was assessed at the beginning and at the end of a 6 weeks therapy. RESULTS: Thereby we found a significant increase in Religious/Spiritual Well-Being, Awareness and more adequate Coping strategies. This was paralleled by a decrease of psychiatric symptoms. Overall the general assumption of a positive association between spirituality and mental health was affirmed. However, we did not find any differences between the two treatment methods (meditation vs. morning walk). CONCLUSIONS: Both interventions showed the same positive efficacy. Based on these initial results, possibilities and boundaries for the integration of religious/spiritual issues into the treatment of psychiatric patients are discussed.

Dimensions of religious/spiritual well-being and the dark triad of personality.

BACKGROUND: In general, religious/spiritual dimensions are found to be negatively correlated with all kinds of psychiatric disorders such as depression, suicidal ideation and substance abuse. Contrary to these findings, the goal of this study was to investigate the relationship between dimensions of religious/spiritual well-being (RSWB) and less favorable aspects of personality - the so-called 'dark triad' of personality traits, i.e. narcissism, machiavellianism and psychopathy - together with general deficits in personality structure. SAMPLING AND METHODS: A total of 312 college students (220 females) completed the Multidimensional Inventory for RSWB, the revised Narcissistic Personality Inventory, the Machiavellianism Inventory and the Levenson Self-Report Psychopathy Scale along with the 16-item Inventory of Personality Organization. RESULTS: RSWB was confirmed to be negatively correlated with these negative aspects of personality, in particular with subclinical psychopathy. More specifically, there were several notable overlaps; narcissism, for instance, was found to be significantly positively associated with some RSWB subdimensions such as 'hope' or 'connectedness'. CONCLUSIONS: First deductions can be made from these data concerning an ambivalent role of spirituality in impaired personality structure. These associations might be further investigated especially in psychiatric patients diagnosed with personality disorders in order to describe potential psychopathological facets of religion and spirituality more adequately.

Alpha power increases in right parietal cortex reflects focused internal attention.

This study investigated the functional significance of EEG alpha power increases, a finding that is consistently observed in various memory tasks and specifically during divergent thinking. It was previously shown that alpha power is increased when tasks are performed in mind-e.g., when bottom-up processing is prevented. This study aimed to examine the effect of task-immanent differences in bottom-up processing demands by comparing two divergent thinking tasks, one intrinsically relying on bottom-up processing (sensory-intake task) and one that is not (sensory-independence task). In both tasks, stimuli were masked in half of the trials to establish conditions of higher and lower internal processing demands. In line with the hypotheses, internal processing affected performance and led to increases in alpha power only in the sensory-intake task, whereas the sensory-independence task showed high levels of task-related alpha power in both conditions. Interestingly, conditions involving focused internal attention showed a clear lateralization with higher alpha power in parietal regions of the right hemisphere. Considering evidence from fMRI studies, right-parietal alpha power increases may correspond to a deactivation of the right temporoparietal junction, reflecting an inhibition of the ventral attention network. Inhibition of this region is thought to prevent reorienting to irrelevant stimulation during goal-driven, top-down behavior, which may serve the executive function of task shielding during demanding cognitive tasks such as idea generation and mental imagery.

[Religious/spiritual well-being in mentally ill persons: a comparison of anxious/depressives, addicts and healthy controls]. / Religiös/Spirituelles Befinden bei psychisch Kranken: Ängstlich/Depressive und Suchtkranke im Vergleich zu gesunden Kontrollpersonen.

OBJECTIVE: The aim of this study is to investigate different dimensions of religiosity and spirituality among psychiatric in-patients. The study examines differences between addictive (ICD 10: F1x) and anxious/depressive (ICD 10: F3x/F4x) patients and considers the main implications for treatment. METHOD: Differences in dimensions of religious/spiritual well-being (RSWB) between addictive (n = 389) and anxious/depressive patients (n = 200) are investigated, also by comparison to a control group (n = 1,500). Furthermore dimensions of RSWB are related to personality factors and different psychiatric parameters within the psychiatric groups. RESULTS: The psychiatric groups show a lower amount of overall RSWB (p < 0.001) than the healthy controls. Furthermore, dimensions of RSWB turned out to be negatively correlated with several psychiatric symptoms. CONCLUSIONS: Based on these results we emphasize religious/spiritual issues within psychiatric treatment. Moreover, there may be a strong potential of the RSWB dimensions such as "Hope" or "Forgiveness" as positive therapeutic factors in psychiatric treatment.

[Creativity in cannabis-users and in drug addicts in maintenance treatment and in rehabilitation]. / Kreativität bei Drogenkonsumierenden, Drogenabhängigen und Drogenentwöhnten.

The main aim of this study was to investigate potential differences between different groups of drug addicts (patients in maintenance treatment, n = 14; patients in rehabilitation, n = 12) and Cannabis-Users (n = 13), along with a healthy control group (n = 18), with respect to verbal and figural creativity and general cognitive ability. Participants worked on different measures for the assessment of different facets of creativity, intelligence and experienced psychiatric symptoms. The results indicated that patients in maintenance and, to some extent Cannabis-Users scored higher regarding verbal creativity than patients in rehabilitation. With respect to figural creativity we observed no differences between the experimental groups. Concerning the Big Five personality traits, patients in maintenance treatment scored highest on Neuroticism while on a purely descriptive level Cannabis-Users achieved the highest scores with respect to openness to experience and extraversion.

State-dependent changes of prefrontal-posterior coupling in the context of affective processing: susceptibility to humor.

The aim of the present study was to examine whether interindividual differences in the coupling or decoupling of prefrontal and posterior cortices during the exposure to social-emotional information may predict an individual's positive emotional responsiveness. Susceptibility to humor was assessed in a behavioral paradigm several weeks after the EEG recordings. State-dependent changes of prefrontal-posterior EEG beta coherence were recorded during stimulation with other people's auditory expressions of cheerfulness and sadness. Greater decreases of coherence during the stimulation with positive affect expressions prospectively predicted greater positive emotional responsiveness, indicated by higher amusement ratings in response to cartoons and higher scores in a questionnaire measure of exhilarability. Greater increases of coherence during the stimulation with negative affect expressions did not predict perceived funniness but were related to shorter response latencies to the amusement ratings. The results further support the notion that a more loose prefrontal-posterior coupling may be related to loosening of control of the prefrontal cortex over incoming emotional information and, thus, to a propensity to deeper emotional involvement and a greater impact of perceptual input, whereas increased prefrontal-posterior coupling may be related to strong control and the propensity to protect oneself from becoming emotionally affected.

Brain correlates underlying creative thinking: EEG alpha activity in professional vs. novice dancers.

Neuroscientific research on creativity has revealed valuable insights into possible brain correlates underlying this complex mental ability domain. However, most of the studies investigated brain activity during the performance of comparatively simple (verbal) type of tasks and the majority of studies focused on samples of the normal population. In this study we investigate EEG activity in professional dancers (n=15) who have attained a high level of expertise in this domain. This group was compared with a group of novices (n=17) who have only basic experience in dancing and completed no comprehensive training in this field. The EEG was recorded during performance of two different dancing imagery tasks which differed with respect to creative demands. In the first task participants were instructed to mentally perform a dance which should be as unique and original as possible (improvisation dance). In the waltz task they were asked to imagine dancing the waltz, a standard dance which involves a sequence of monotonous steps (lower creative demands). In addition, brain activity was also measured during performance of the Alternative Uses test. We observed evidence that during the generation of alternative uses professional dancers show stronger alpha synchronization in posterior parietal brain regions than novice dancers. During improvisation dance, professional dancers exhibited more right-hemispheric alpha synchronization than the group of novices did, while during imagining dancing the waltz no significant group differences emerged. The findings complement and extend existing findings on the relationship between EEG alpha activity and creative thinking.

EEG alpha oscillations during the performance of verbal creativity tasks: differential effects of sex and verbal intelligence.

Task-related power changes in the EEG alpha band were analyzed in 31 participants (17 males and 14 females) during performance of two verbal creativity tasks. Participants were confronted with verbal problems that are in need of explanation (insight problems) and utopian situations that will actually never happen. In both tasks they were instructed to generate as many but also as unusual, unique or original ideas as possible. To assess brain responses that come along with highly original ideas, individual responses were divided into more and less original ideas (within each participant). Creative problem solving was generally accompanied by lower levels of cortical arousal (i.e., increases in alpha power from a pre-stimulus reference to an activation interval). Additionally, more original (vs. less original) responses were associated with a stronger task-related alpha synchronization in posterior (particularly centroparietal) cortices. Task-related alpha power changes during creative problem solving were also moderated by verbal IQ and sex.
