The surprise element: A hallmark of creativity in scientists, artists, and comedians.

Truly creative works of science and art produce unexpected and surprising results-just like the punch line of a good joke that generates an unfamiliar twist on a familiar idea. Surprise stimulates curiosity, which triggers a search to reveal the mystery of things unknown.

Enhancing cognitive control of our decisions: Making the most of humor during the IGT in females and males.

We studied the impact of humor on the Iowa Gambling Task (IGT) decision-making performance and the cognitive control exerted during this task, considering sex as a moderator, and examined whether cognitive control mediated the influence of humor on decision-making. Sixty participants (30 females) performed an extended version of the IGT (500 trials divided into 20 blocks). We randomly assigned them to either an experimental group (Humor Group; Hg; n = 30), where humorous videos were interspersed in the decision-making trials or a control group (Non-Humor Group; NHg; n = 30), where nonhumorous videos were interspersed in the decision-making trials. We recorded participant performance and feedback-related negativity (FRN) and P3b event-related potentials (ERP) during IGT feedback as task monitoring and attention allocation indicators, respectively. We expected that whereas humor would improve IGT decision-making under risk in females during the last blocks (17-20) as well as cognitive control (specifically attention allocation and task monitoring) across the entire IGT, it would impair them in males. Contrary to our expectations, humor improved IGT decision-making under risk for both sexes (specifically at blocks 19 and 20) and attention allocation for most IGT blocks (P3b amplitudes). However, humor impaired IGT decision-making under ambiguity in males during the block six and task monitoring (FRN amplitudes) for most IGT blocks. Attention allocation did not mediate the beneficial effect of humor on decision-making under risk in either sex. Task monitoring decrements fully mediated the humor's detrimental influence on men's decision-making under ambiguity during block six.

Boosts for walking: how humorous messages increase brisk walking among cognitively fatigued individuals.

BACKGROUND: A well-studied internal barrier to regular physical activity, and more specifically brisk walking, is cognitive fatigue. However, thus far little research examined how cognitively fatigued individuals can be motivated to exercise, more specifically to engage in brisk walking. This study investigates whether humorous intervention messages might be an effective strategy to motivate cognitively fatigued individuals to brisk walk, and through which underlying processes. METHODS: An online experiment was performed in which variation in cognitive fatigue was induced through mental arithmetic questions. Afterwards, participants (n = 250) recruited through Prolific, randomly received either humorous or non-humorous intervention messages related to brisk walking. Potential mediators of the relations between physical activity, humour and cognitive fatigue were measured, were self-efficacy, self-control, and motivation. RESULTS: First, regression analyses confirmed that cognitive fatigue negatively influences brisk walking intentions and that the perceived humour of the intervention messages moderated this relationship. Second, results showed that self-control and self-efficacy are mediators explaining the relationship between cognitive fatigue and brisk walking intentions. Lastly, this study found that perceived humour of the intervention messages moderated the relationship between cognitive fatigue and self-control, indicating that perceptions of self-control were positively changed after receiving messages that were perceived as humorous compared to messages that were not perceived as humorous, subsequently increasing brisk walking intentions. CONCLUSIONS: This study is the first to unravel the underlying relationship between humorous intervention messages and brisk walking intentions through positive changes in perceptions of self-control within a cognitively fatigued sample. Results of this study suggest that existing smartphone applications monitoring and promoting brisk walking should integrate tailored message strategies within their cues to brisk walk by implementing humour as a strategy to motivate users when they are cognitively fatigued.

Humor and Laughter in Health Promotion Interventions and the COVID-19 Pandemic: A Cross-Disciplinary Narrative Review.

The evolution and purpose of humor have long been of interest to the scientific community. Humor and laughter play an important role in social, emotional, mental, and physical health and well-being. The purpose of this narrative review is to explore perspectives and research findings of studies on the role of humor and laughter in health promotion and direct care interventions throughout the COVID-19 pandemic. Also discussed is the cross-disciplinary context of studies during the global pandemic, which illustrates the complexity of humor in human behavior and its manifestation in healthcare environments and public health outcomes. This review of studies on humor and laughter behaviors employed during the COVID-19 pandemic points to the need for further work on the potential of humor and laughter for use in direct care interventions, health messaging, health education, and in improving the social bonds and connections among health professionals, patients, and students.

A participatory approach to understand what might be most meaningful to people living with dementia in a positive psychology intervention.

OBJECTIVES: This study aimed to understand which character strengths are most important for people living with dementia and therefore which strengths-based psychological interventions could be most meaningful and acceptable. METHODS: A participatory design, utilising Delphi methodology, was incorporated into an iterative three stage framework: (1) literature reviewed for Positive Psychology (PP) interventions and patient public involvement to define the character strengths; (2) modified Delphi (N = 10) identified which character strengths are most important for living with dementia; (3) focus groups (N = 14) explored which PP interventions are most acceptable and meaningful. Qualitative data from the focus groups was analysed using thematic analysis. RESULTS: Love, kindness and humour were deemed the most important character strengths for living with dementia. Qualitative data from the focus groups was captured in three superordinate themes: (1) lack of opportunity not capacity; (2) key considerations of PP interventions for people living with dementia; and (3) potential benefits of PP interventions. CONCLUSIONS: Love, kindness and humour come naturally to people with dementia, but people may lack social opportunities to use these strengths. Therefore, a PP intervention promoting positive emotion, social relationships and connection to one's values appears most meaningful and acceptable as this may provide a social context to use and maintain these strengths.

Funny? Think About It! Selective effect of cognitive mechanisms of humour on insight problems.

The present study aims to elucidate whether insight problem solving could be facilitated by the cognitive component of humour. The authors take interest in whether the logical mechanisms of humour can affect how fast insight problems are solved. To that end, the authors conducted two experiments where participants solved insight problems after watching visual humorous stimuli such as videos and slideshows. The first experiment demonstrated the overall impact of facilitation by humour on insight problem solving; however, it did not show any difference in how particular logical mechanisms of humour affect the solution time of insight problems. The second experiment showed that the cognitive component of humour could selectively affect insight problems whose difficulty stems from different sources. These results suggest that the cognitive component of humour, when operationalised as logical mechanisms and schema switching, contributes to solving insight problems.

Humor Styles in Healthcare Professionals: A Correlational Study.

Using humor as a caregiving strategy can help professionals perceive daily and work-related events from a more optimistic and light-hearted perspective. The main objective of this study was to analyze humor styles among health care professionals. A cross-sectional and correlational design was employed. Data were collected using the Humor Styles Questionnaire, which measures four humor styles: affiliative, self-enhancing, aggressive, and self-defeating humor. Health care professionals scored higher in positive humor than negative humor. Age exhibited a negative correlation with positive humor. Significant differences were observed between marital status and affiliative and self-enhancing humor, professional category and hospital unit with aggressive humor, shift work and self-enhancing humor, and type of contract and experience with affiliative humor. Health care professionals employ various humor styles based on their social and work contexts. It is crucial for health care professionals to receive training in the use of positive humor to consciously avoid humor styles that can hinder well-being.

Effect of Humor on Pain and Anxiety in Patients With Rheumatoid Arthritis: A Prospective, Randomized Controlled Study.

Humor can contribute to nursing practices for relieving pain and anxiety in patients with rheumatoid arthritis (RA) during intravenous (IV) biologic treatment. This study used a prospective, randomized controlled study design to investigate the effect of humor on pain and state anxiety in patients with RA receiving IV infusion therapy. Two sample groups were formed: the intervention group (watching a comedy movie) (n = 18) and the control group (usual care) (n = 18). Both groups received IV biologic therapy. A significant difference was found between the groups' pain mean scores, but the effect size was small (P < .001, η² = 0.032). The mean visual analog scale scores decreased in both groups after the treatment; however, it decreased more in the intervention group (P < .001, Md = 2.44) than in the control group (P = .017, Md = 0.83). No significant difference was found between the groups' mean state anxiety scores, and the effect size was irrelevant (P > .05, η² = 0.001). There was a significant decrease in the anxiety levels of both groups (P < .001). During IV biologic infusion therapy, watching comedy movies is recommended as a nursing care intervention for reducing pain in patients with RA in cooperation with other health professionals.

Humor in autism spectrum disorders: A systematic review.

OBJECTIVES: Humor is essential to social relationships. Its use and understanding appear to be impaired in people with Autism Spectrum Disorder (ASD). The main objective was to review the existing literature on the detection, understanding and use of humor in persons with ASD. The secondary objective involved exploring assessment scales and specific intervention tools. METHODS: A systematic review of the literature was carried out on all available French and English scientific papers about humor - including irony - in persons with ASD up to November 2021. We extracted 552 references and included 43 articles from six databases. RESULTS: Studies suggest that those with ASD can detect audiovisual and written humor. Understanding humor was impaired in writing and when using pure auditory stimuli and non-verbal cartoons. For irony, the results indicated a lower detection of quality and less understanding in speaking but not in writing. Regarding its use, in terms of expression, people with ASD use benevolent humor less often and do not consider humor as a key source of satisfaction with life, as opposed to the control group. CONCLUSIONS: It appears that it would be worthwhile to develop standardized humor detection and assessment tools specific to persons with ASD. Practical strategies that focus on humor ability could be worth developing, either individually or in groups.

Associations of humor, morale, and unit cohesion on posttraumatic stress disorder symptoms.

Military personnel experience many stressors during deployments that can lead to symptoms of posttraumatic stress disorder (PTSD). However, not all military personnel who are exposed to deployment stressors develop PTSD symptoms. Recent research has explored factors that contribute to military personnel resilience, a multifaceted and multidetermined construct, as a means to mitigate and prevent PTSD symptoms. Much of this research has focused on the effects of individual-level factors (e.g., use of coping strategies like humor, the morale of individual unit members), with some research focusing on unit-level factors (e.g., the cohesiveness of a unit). However, there is little research exploring how these factors relate to each other in mitigating or reducing PTSD symptoms. In this study, we examined the association between deployment stressors, perceived unit cohesion, morale, humor, and PTSD symptoms in a sample of 20,901 active-duty military personnel using structural equation modeling. Results indicated that perceived unit cohesion, humor, and morale were positively associated with each other and negatively associated with PTSD symptoms over and above the effect of deployment stressors. These findings highlight the influence of resilience factors on PTSD symptoms beyond their substantial overlap and have implications for future research as well as the potential development of interventions for military personnel.

Effect of Humour on Pain Perception among Young Healthy Indian Adults Using Cold Pressor Task.

Background Currently there is little research, especially in India, which has looked at the physiological effects of humour on pain perception. Objective To compare pain sensitivity across the three arms of intervention (control, neutral and funny videos). And to investigate the relationship between a) cardiovascular responses across and within each arm, b) pain sensitivity and resting blood pressure, pulse rate, c) humour trait with pain sensitivity. Method Subjects were exposed in random order to cold pressor task, during which they either watched a 'neutral video' or 'funny video' or did not watch any video. During the intervention, pain threshold and tolerance were recorded. Systolic and diastolic blood pressure, and pulse rate were measured before and after intervention. Pain unpleasantness was recorded post intervention. Result Neither humorous nor neutral videos had a significant effect on pain threshold, tolerance and unpleasantness and cardiovascular responses. There was significant difference between the pre and post values of cardiovascular measures within neutral and funny video arms. In the 'no video' arm, negative correlations were found between resting blood pressure and pain unpleasantness, and between delta diastolic blood pressure and pain threshold. Humour trait and subject's self-rating of pain tolerance had no effect on both pain sensitivity and cardiovascular responses to cold pain. Conclusion Humorous distraction had no effect on objective or subjective pain measures or cardiovascular responses to cold pain exposure. There was a significant difference in the pre-post values of cardiovascular measures within neutral and funny video arms.

"Sorry for laughing, but it's scary": humor and silence in discussions of Colorectal Cancer with Urban American Indians.

BACKGROUND: Given high rates of cancer mortality in Native communities, we examined how urban American Indian and Alaska Native elders talk about colorectal cancer (CRC) and CRC screening. METHODS: We conducted seven focus groups with a total of 46 participants in two urban clinics in the Pacific Northwest to assess participant awareness, perceptions, and concerns about CRC and CRC screening. Using speech codes theory, we identified norms that govern when and how to talk about CRC in this population. RESULTS: Our analyses revealed that male participants often avoided screening because they perceived it as emasculating, whereas women often avoided screening because of embarrassment and past trauma resulting from sexual abuse. Both men and women used humor to mitigate the threatening nature of discussions about CRC and CRC screening. CONCLUSIONS: We offer our analytic results to assist others in developing culturally appropriate interventions to promote CRC screening among American Indians and Alaska Natives.

The predator becomes the prey: regulating the ubiquitin system by ubiquitylation and degradation.

Ubiquitylation (also known as ubiquitination) regulates essentially all of the intracellular processes in eukaryotes through highly specific modification of numerous cellular proteins, which is often tightly regulated in a spatial and temporal manner. Although most often associated with proteasomal degradation, ubiquitylation frequently serves non-proteolytic functions. In light of its central roles in cellular regulation, it has not been surprising to find that many of the components of the ubiquitin system itself are regulated by ubiquitylation. This observation has broad implications for pathophysiology.

Humour interventions for patients in palliative care-a randomized controlled trial.

PURPOSE: The effect of humour on end-of-life patients could be beneficial and is worth investigating. However, data on humour interventions for patients in palliative care are scarce. This study evaluated the effects of a humour intervention in a palliative care setting. METHODS: A two-step intervention was developed based on the humour habits programme by McGhee. Patients were assisted to remember funny episodes from their past and recognize humorous aspects of the present and encouraged to produce humour. The intervention and control group completed questionnaires on life satisfaction, cheerfulness, symptom burden, and perceived stress and if possible gave saliva samples to investigate oxytocin levels. The study was a randomized controlled monocentre study on patients treated in a palliative care ward. Participants had to be conscious and alert enough to complete data collection. Overall, 55 patients were included and randomized to the intervention or control group. RESULTS: Parameters in the control group did not change significantly. In the intervention group, seriousness, bad mood, and stress were reduced. Cheerfulness increased significantly after the intervention. However, the methodologically complex intervention setting was too exhausting for the majority of patients. CONCLUSION: Patients who were able to participate benefited from the effects of the intervention on multiple levels. For future research simple interventions, biomarkers for well-being and assessments by staff or proxies are needed to include patients with reduced cognitive and physical performance status at the end of their lives.

Dynamic cognitive processes of humor generation: activation and inhibition of information.

Humor is a lubricant of interpersonal relationships and is regarded as an important quality of individual creativity. Previous studies have mainly focused on passive humor appreciation and comprehension but ignored active humor generation, especially the cognitive process of humor generation. Based on the hypothesis that humor generation is similar to creative cognition, this study used humorous two-part allegorical sayings to explore whether humor generation involves the cognitive processes of the activation and inhibition of information. The experiment manipulated the duration (5/10 s) of the presentation of the first part of humorous two-part allegorical sayings, which are called "yinyu," and the type of subthreshold probe words (humorous probe words/usual probe words). The results showed that the interaction between the duration of the presentation of yinyu and the type of subthreshold probe words was significant; the correct number of humorous probe words reported was significantly lower than that of usual probe words when the yinyu was presented for 5 s, which reflected the widespread activation of information. The correct number of humorous probe words reported was significantly higher than that of usual probe words when the yinyu was presented for 10 s, which suggested the inhibition of non-humorous information. This study revealed the dynamic cognitive processes of humor generation and verified possible cognitive similarities between humor generation and creative cognition.

Mechanical Dentistry: George Derby, An Unknown Artist, and Rube Goldberg.

For more than a century, at least, tooth extraction by ingenious mechanical contraptions has piqued the interest and imagination of illustrators, especially cartoonists. George Derby, an unknown British talent, and Ruben Garrett Lucius "Rube" Goldberg all dabbled in oral surgical mechanical humor.
