The Use of Bright and Dark Types of Humour is Rooted in the Brain

Understanding the Association Between Humor and Emotional Distress: The Role of Light and Dark Humor in Predicting Depression, Anxiety, and Stress

Despite increasing interest in the relationship between humor and psychological distress, investigations have failed to focus on specific categories of humor and negative mental conditions. A sample of 686 Italian participants (187 men and 499 women), aged between 20 and 76 years, completed an online survey, data from which was used to investigate the relationship between eight comic styles, depression, anxiety, and stress. Findings from the multiple linear regression demonstrate benign humor as a protective factor of all three variables considered, while irony was positively associated with anxiety and stress. Wit was a protective factor associated with anxiety, while sarcasm was positively related to depression. No significant correlations emerged between the other variables considered. These findings highlight how specific categories are linked to varying dimensions of emotional distress, which are discussed with reference to the extant literature.

Enjoying others' distress and indifferent to threat? Changes in prefrontal-posterior coupling during social-emotional processing are linked to malevolent creativity

Malevolent creativity is characterized by malicious interpersonal goals aimed at damaging others. Neurocognitive processing patterns of negative social-emotional signals may explain variance in this disruptive phenomenon. This study examined whether individuals' brain responses to emotional expressions of others are linked to their capacity of malevolent creativity in a psychometric test. State-dependent changes of prefrontal-posterior EEG coherence were recorded while n = 60 participants listened to other people's anger, desperate crying, and laughter. These EEG measures were used to indicate affective dispositions towards emotional absorption (decreased coherence) or detachment (increased coherence) from others' emotional states. Results showed that higher malevolent creativity was reflected in relatively greater increases of EEG coherence during others' expressions of anger, and conversely, relatively greater decreases of EEG coherence during others' desperate crying. This pattern suggests that the generation of creative ideas for malicious, antisocial purposes may be partly attributed to an indifference towards others' aggression and potential retaliation, and partly to finding others' adversity rewarding on a neuronal level, increasing the quantity of ideas and the chances of hurting others. This first study linking malevolent creativity to social-emotional brain functions may offer novel insights into affective dispositions that may help understand individuals' potential for creative destruction.

More creative ideas are associated with increased right posterior power and frontal-parietal/occipital coupling in the upper alpha band: A within-subjects study

The neurophysiological investigation of creative idea generation is a growing research area. EEG studies congruently reported the sensitivity of upper alpha power (10-12 Hz) for the creative ideation process and its outcome. However, the majority of studies were between-subject design studies and research directly comparing the neurophysiological activation pattern when generating more and less creative ideas within a person are rare. Therefore, the present study was specifically focused on investigating brain activation patterns associated with the generation of more vs. less creative ideas. We applied an alternate uses task (AU-task; i.e., finding original uses for everyday objects such as a brick) in a sample of 74 participants and recorded the brain activation during the AU-task and reference period. A portable EEG system with 21 dry electrodes arranged in the international 10-20 system and linked ear as reference was used. We found a higher increase of upper alpha power during creative ideation (relative to reference period, i.e., task-related power, TRP) over right posterior sites when people generated more compared to less creative ideas. This was accompanied by an increase of functional coupling (i.e., task-related coherence increase) between frontal and parietal/occipital sites, which suggests higher internal attention and more control over sensory processes. Taken together, these findings complement the existing creativity research literature and indicate the importance of alpha power for the creative ideation process also within people.

Creativity in an Affective Context

Abstract. Everyday life often requires considerable creativity in dealing with challenging circumstances. This implies that creativity regularly operates in an affective context, however, this “C” of creativity is rarely addressed in contemporary research. In this brief review article, we address some important milestones in this nascent field of research. Starting with early accounts on emotional creativity, we discuss seminal research intertwining creativity and mood states, and finally introduce two recent developments in this field: reappraisal inventiveness as the capacity to generate manifold cognitive reappraisals for aversive situations, and malevolent creativity as creative ideation intentionally used to damage others. We discuss the conceptual origins of reappraisal inventiveness and malevolent creativity and provide an extensive review of past behavioral and neuroscientific findings regarding these differently motivated instances of affective creativity. Additionally, novel pilot findings and prospects on both lines of research will be provided, which may help to advance investigations into more real-world applications of creative cognition.

Creativity is associated with a characteristic U-shaped function of alpha power changes accompanied by an early increase in functional coupling

Although there exists increasing knowledge about brain correlates underlying creative ideation in general, the specific neurocognitive mechanisms implicated in different stages of the creative thinking process are still under-researched. Some recent EEG studies suggested that alpha power during creative ideation varies as a function of time, with the highest levels of alpha power after stimulus onset and at the end of the creative thinking process. The main aim of the present study was to replicate and extend this finding by applying an individual differences approach, and by investigating functional coupling between long distance cortical sites during the process of creative ideation. Eighty-six participants performed the Alternate Uses (AU) task during EEG assessment. Results revealed that more original people showed increased alpha power after stimulus onset and before finalizing the process of idea generation. This U-shaped alpha power pattern was accompanied by an early increase in functional communication between frontal and parietal-occipital sites during the creative thinking process, putatively indicating activation of top-down executive control processes. Participants with lower originality showed no significant time-related variation in alpha power and a delayed increase in long distance functional communication. These findings are in line with dual process models of creative ideation and support the idea that increased alpha power at the beginning of the creative ideation process may indicate more associative modes of thinking and memory processes, while the alpha increases at later stages may indicate executive control processes, associated with idea elaboration/evaluation.

Motivational Factors in the Typical Display of Humor and Creative Potential: The Case of Malevolent Creativity

Research is still disputing if an individual's use of humor in everyday life is also indicative of his or her creative potential. To date, the focus has been mainly restricted to shared cognitive factors, while motivational aspects that may link the production of humor and of creative ideas have been largely neglected. Humor motivation implicates latent social goals the creator pursues through the use of humor. These goals can be benign or more malicious and manifest in an individual's typical display of comic styles. While often overlooked, creativity often serves social functions as well, especially in common everyday situations. Similar to humor, creativity is typically regarded as beneficial for individuals and society. Yet, creative ideas may also originate from less prosocial goals. This is reflected in the concept of malevolent creativity, where novel ideas are generated to deliberately harm others. The present study investigated individuals' typical display of humor, differentiated in eight distinct comic styles in relation to their productivity in a behavioral test for malevolent creativity and general creative potential (n = 106). Individuals with higher scores on comic styles that are affiliated with malicious interpersonal goals - such as hurting or upsetting others or demonstrating superiority over others - were more fluent in producing malevolent creative ideas in the malevolent creativity test. This finding shows that individual differences in humor motivation relate to the capacity of coming up with relevant creative ideas also outside the domain of humor. The pattern of relationships between humor motivation and general creative potential differed from that of malicious creativity and implied the comic style "wit" only, primarily adding to the notion of shared cognitive processes in the production of humor and creative ideas. The study offers a novel perspective for how the inclusion of motivational factors that are inherent to conceptualizations of humor may also benefit creativity research.

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.

The effect of humour on nursing professionals' psychological well-being goes beyond the influence of empathy: a cross-sectional study

BACKGROUND

Prior research has underlined the meaningful function of humour in nursing settings. Nonetheless, most of the empirical evidence on humour and nursing derives from approaches that mainly considered the potential beneficial effects of humour, neglecting potential detrimental effects of the dark side of humour. Moreover, little is known about whether the specific repercussions of humour on healthcare professionals' well-being would go beyond empathy-a construct robustly related to psychological well-being.

AIMS

To examine whether distinctive humour styles (affiliative, self-enhancing, aggressive and self-defeating) are differentially associated with the psychological well-being of nursing professionals. Importantly, we also analysed whether these potential humour effects go over and above the influence of empathy-related traits (perspective-taking and personal distress).

METHOD

A cross-sectional, descriptive correlational design was used. A convenience sample of 104 nursing professionals with a minimum work experience of one year was recruited.

RESULTS

Our results revealed that a greater inclination to affiliative and self-enhancing humour styles was strongly related to higher scores on happiness, sociability, hope and life satisfaction among nursing professionals. Concerning maladaptive humour styles, aggressive humour was related to low life satisfaction and high nursing stress. By contrast, self-defeating humour-a theoretically detrimental humour style-was related to higher scores on health among these professionals. These effects emerged even after controlling for the influence of demographics (i.e., gender, age and years of experience), perspective-taking and personal distress.

CONCLUSIONS

Our results suggest that adaptive humour styles may promote positive indicators of well-being, but they might not protect against negative indicators. Moreover, differential effects of maladaptive humour styles emerged. Whereas aggressive humoristic expressions can be interpreted as a sign of a poor psychological functioning, self-defeating humour may boost positive psychological outcomes among nursing professionals. These data can help to design more efficient humour-based intervention programmes aimed at minimising potential negative consequences of nursing activity.

Prefrontal-posterior coupling mediates transitions between emotional states and influences executive functioning

Emotions often result from fluctuating experiences with self-regulation unfolding over time. However, most research has been focused on neural responses to static, affective stimuli. We studied emotion transitions, which correspond to dynamic conditions of varying affective valence or intensities. Functional coupling of prefrontal and posterior cortex (EEG coherence) was recorded during exposure to stable versus changing emotion-eliciting images (static vs. dynamic conditions). Prefrontal-posterior coupling was decreased in the dynamic conditions compared to the static conditions. A decrease in prefrontal-posterior coupling implies less control of the prefrontal cortex over perceptual information, which may allow the brain to become more affected by emotional fluctuations. We also assessed the aftereffect of EEG coherence on executive functioning, utilizing the flanker task. Among individuals reporting higher chronic stress, executive functioning decreased after dynamic conditions. This decrease in executive functioning was mediated by the decrease in prefrontal-posterior coupling in the dynamic conditions. These findings suggest that the strength of prefrontal-posterior coupling is not only related to emotional transitions but also to executive functioning. The deterioration of executive functioning after dynamic emotional processing may reflect the additional cognitive effort required to process dynamic shifts in affective stimuli, and this relationship is exacerbated by chronic stress.

Humorous cognitive reappraisal: More benign humour and less "dark" humour is affiliated with more adaptive cognitive reappraisal strategies

The capacity to find humorous perspectives in aversive situations may outline a helpful strategy in the context of cognitive reappraisal. Yet, research suggested that some people produce more adaptive humour than others. At the same time, not all forms of cognitive reinterpretation seem to be unequivocally beneficial. The present study aimed to investigate specific cognitive reappraisal strategies that individuals employ in humorous reappraisal of adverse events. In a sample of 95 participants, the use of cognitive reappraisal sub-strategies was assessed in a behavioural test in which participants were required to generate a series of humorous reappraisals of self-relevant, threatening events. These reappraisal sub-strategies (three positive reinterpretation strategies, three de-emphasising strategies) were then related to the habitual use of different kinds of humour as well as the broader DSM-5 personality trait domains and well-being in terms of depressive experiences, assessed by self-report questionnaires. While no robust relationships were found for reappraisal strategies based on de-emphasising, sub-strategies within the positive reinterpretation category showed specific and contrasting associations with the examined traits. Findings indicated that the ability to produce humour is only linked to a favourable pattern of reappraisal strategies when manifested in benign forms of humour. Specific relations also emerged for the broader personality traits. The study suggests that some characteristics that advance the use of benign humour also benefit adaptive emotion regulation. The opposite seems to be true for malicious, or "dark" humour. The introduced behavioural approach to the analysis of humorous cognitive reappraisal may prove useful also in future related research.

Broadening Humor: Comic Styles Differentially Tap into Temperament, Character, and Ability

The present study introduces eight comic styles (i.e., fun, humor, nonsense, wit, irony, satire, sarcasm, and cynicism) and examines the validity of a set of 48 marker items for their assessment, the Comic Style Markers (CSM). These styles were originally developed to describe literary work and are used here to describe individual differences. Study 1 examines whether the eight styles can be distinguished empirically, in self- and other-reports, and in two languages. In different samples of altogether more than 1500 adult participants, the CSM was developed and evaluated with respect to internal consistency, homogeneity, test-retest reliability, factorial validity, and construct and criterion validity. Internal consistency was sufficiently high, and the median test-retest reliability over a period of 1-2 weeks was 0.86 (N = 148). Exploratory and confirmatory factor analyses showed that the eight styles could be distinguished in both English- (N = 303) and German-speaking samples (N = 1018 and 368). Comparing self- and other-reports (N = 210) supported both convergent and discriminant validity. The intercorrelations among the eight scales ranged from close to zero (between humor and sarcasm/cynicism) to large and positive (between sarcasm and cynicism). Consequently, second-order factor analyses revealed either two bipolar factors (based on ipsative data) or three unipolar factors (based on normative data). Study 2 related the CSM to instruments measuring personality (N = 999), intelligence (N = 214), and character strengths (N = 252), showing that (a) wit was the only style correlated with (verbal) intelligence, (b) fun was related to indicators of vitality and extraversion, (c) humor was related to character strengths of the heart, and (d) comic styles related to mock/ridicule (i.e., sarcasm, cynicism, but also irony) correlated negatively with character strengths of the virtues temperance, transcendence, and humanity. By contrast, satire had a moral goodness that was lacking in sarcasm and cynicism. Most importantly, the two studies revealed that humor might be related to a variety of character strengths depending on the comic style utilized, and that more styles may be distinguished than has been done in the past. The CSM is recommended for future explorations and refinements of comic styles.
