“…Decreased EEG alpha power over frontal sites, particularly in the upper alpha band (~10–14 Hz) has been linked to semantic processing (Doppelmayr, Klimesch, Stadler, Pöllhuber, & Heine, ; Klimesch, ; Klimesch, Sauseng, & Hanslmayr, ; Klimesch, Schimke, & Pfurtscheller, ). Consistent with a role of semantic memory in visual creativity, widespread upper alpha power reductions which included frontal regions were observed in several studies compared to baseline (e.g., Molle et al., ; Nagornova, ; Petsche et al., ) and/or compared to control task performance (Jaarsveld et al., ; Jausovec & Jausovec, ). Upper alpha reductions were prominent over frontal sites in the latter two studies.…”

“…In the low‐frequency delta and theta bands and the lower and upper alpha bands, a consistent pattern of decreases in EEG power during visual creativity compared to baseline fixation or rest— task‐related desynchronization (TRD) emerged across studies (Jaarsveld et al., ; Jausovec & Jausovec, ; Petsche et al., ; Volf & Tarasova, , ; Volf et al., ). Predominant increases in power versus baseline, task‐related synchronization (TRS), were observed in the high‐frequency beta and gamma bands (Molle, Marshall, Wolf, Fehm, & Born, ; Nagornova, ; Razumnikova, Volf, & Tarasova, , ; Sviderskaya, ; Volf & Tarasova, ).…”

“…Most experiments (60%) employed tasks emphasizing the originality and/or fluency of solutions, including the TTCT‐IF or similar variants, or mental combination of shapes to form original images. In two studies (Bhattacharya & Petsche, ; Petsche et al., , Experiment 1), participants generated esthetically pleasing images, while in three studies, participants generated functional solutions, for example, generating a novel visual intelligence test (Jaarsveld et al., ) or a visual representation of an abstract concept (Petsche, ; Petsche et al., , Experiment 3).…”

“…() reported reduced interhemispheric frontal alpha coherence during visual creativity, interpreting this as increased independence of left and right PFC functions. Some studies also reported that task‐related power increases or decreases were particularly evident at frontal sites (Jaarsveld et al., ; Jausovec & Jausovec, ). Further behavioral and neuroimaging studies including EEG studies employing source localization in addition to appropriate control tasks are necessary to establish the subregions of PFC and associated cognitive processes contributing to visual creativity.…”

Functional neuroimaging of visual creativity: a systematic review and meta‐analysis

IntroductionThe generation of creative visual imagery contributes to technological and scientific innovation and production of visual art. The underlying cognitive and neural processes are, however, poorly understood.MethodsThis review synthesizes functional neuroimaging studies of visual creativity. Seven functional magnetic resonance imaging (fMRI) and 19 electroencephalography (EEG) studies were included, comprising 27 experiments and around 800 participants.ResultsActivation likelihood estimation meta‐analysis of the fMRI studies comparing visual creativity to non‐rest control tasks yielded significant clusters in thalamus, left fusiform gyrus, and right middle and inferior frontal gyri. The EEG studies revealed a tendency for decreased alpha power during visual creativity compared to baseline, but comparisons of visual creativity to non‐rest control tasks revealed inconsistent findings.ConclusionsThe findings are consistent with suggested contributions to visual creativity of prefrontally mediated inhibition, evaluation, and working memory, as well as visual imagery processes. Findings are discussed in relation to prominent theories of the neural basis of creativity.

“…Equally important, studies have revealed that different alpha ERS/ERD patterns are involved in different stages of the creative process (Schwab, Benedek, Papousek, Weiss & Fink, 2014) as well as the creative reasoning processes (Jaarsveld et al, 2015). The alpha activity of the different phases of the SC remains unclear.…”

Effects of Creative Personality onEEGAlpha Oscillation: Based on the Social and General Creativity Comparative Study

The neural mechanism underlying creativity has been identified and confirmed by numerous studies. This current exploratory study compared the neural basis between social creativity and general creativity and explored the effect of creative personality on their neural basis by employing multiple regression analysis. The EEG activities of 34 participants were recorded during social or general creative tasks. The results indicated that a stronger alpha event‐related synchronization (ERS) was presented during the social creative task than during the general creative task. High creative personality individuals were found to exhibit higher event‐related desynchronization (ERD) only for the upper alpha band. Additionally, high creative personality individuals revealed no significant task differences regarding the alpha ERS. However, low creative personality individuals exhibited a stronger alpha ERS for social creative tasks than they did for general creative tasks. The current investigation could lead to new approaches for examining the brain correlates of creativity from different domains and their correlations with respect to creative personality.

Little is known about creativity in old age. The aim of this study was to investigate to what extent the intensity of engaging in creative activities differs between older and younger people as well as older people with and without cognitive impairment. Moreover, we evaluated associations of creative activities with specific cognitive abilities. For this cross‐sectional study, groups of younger people (n = 24), older cognitively healthy people (n = 24), and older cognitively impaired people (n = 23) were recruited via convenience sampling. Creative activities were assessed via the creative behavior inventory (CBI). Cognitive abilities were assessed via trail making test (TMT), standard progressive matrices (SPM), creative reasoning task (CRT), test of creative thinking‐drawing production (TCT‐DP), and alternate uses task (AUT). The intensity of engaging in creative activities was higher among younger people but was not significantly associated with being cognitively impaired. Only two cognitive abilities, the creative thinking scores CRT‐Components and TCT‐DP‐Original, predicted creative activities. Both did not differ significantly between cognitively healthy and cognitively impaired older adults. The findings suggest that cognitively impaired older people still engage in creative activities, which might be due to their relatively sound creative thinking. Further studies should investigate whether engaging in creative activities can mitigate cognitive decline.
