Functional EEG Alpha Activation Patterns During Malevolent Creativity

[Display omitted] •EEG alpha patterns of malevolent creativity mirror conventional creative ideation.•Time-related activity changes during malevolent creativity were observed.•Early frontal alpha increases may reflect conceptual expansion to antisocial ideas.•Mid-stage temporal alpha increases may indicate remote associations of novel harm.•Right-lateralized activity may signal the emotional load of malevolent ideas. On the dark side of creativity, creative ideation is intentionally used to damage others. This first electroencephalogram (EEG) study on malevolent creativity investigated task-related power (TRP) changes in the alpha band while n = 89 participants (52 women, 37 men) generated original ideas for revenge in the psychometric Malevolent Creativity Test. TRP changes were assessed for different stages of the idea generation process and linked to performance indicators of malevolent creativity. This study revealed three crucial findings: 1) Malevolent creativity yielded topographically distinct alpha power increases similar to conventional creative ideation. 2) Time-related activity changes during malevolent creative ideation were reflected in early prefrontal and mid-stage temporal alpha power increases in individuals with higher malevolent creativity performance. This performance-related, time-sensitive pattern of TRP changes during malevolent creativity may reflect early conceptual expansion from prosocial to antisocial perspectives, and subsequent inhibition of dominant semantic associations in favor of novel revenge ideas. 3) The observed, right-lateralized alpha power increases over the entire ideation phase may denote an additional emotional load of creative ideation. Our study highlights the seminal role of EEG alpha oscillations as a biomarker for creativity, also when creative processes operate in a malevolent context.
