Cooperation is widespread and arguably a pivotal evolutionary force in maintaining animal societies. Yet, proximately, what underlying motivators drive individuals to cooperate remains relatively unclear. Since 'free-riders' can exploit the benefits by cheating, selecting the right partner is paramount. Such decision rules need not be based on complex calculations and can be driven by cognitively less-demanding mechanisms, like social relationships (e.g. kinship, non-kin friendships, dyadic tolerance), social status (e.g. dominance hierarchies) and personalities (social and non-social traits); however, holistic evidence related to those mechanisms is scarce. Using the classical 'loose-string paradigm', we tested cooperative tendencies of a hierarchical primate, the long-tailed macaque (). We studied three groups ( = 21) in their social settings, allowing partner choice. We supplemented cooperation with observational and experimental data on social relationships, dominance hierarchies and personality. Friendship and dissimilarities in non-social 'exploration' and 'activity-sociability' personality traits predicted the likelihood of cooperative dyad formation. Furthermore, the magnitude of cooperative success was positively associated with friendship, low rank-distance and dissimilarity in the activity-sociability trait. Kinship did not affect cooperation. While some findings align with prior studies, the evidence of (non-social) personality heterophily promoting cooperation may deepen our understanding of the proximate mechanisms and, broadly, the evolution of cooperation.

BACKGROUND
Surgeons work long shifts and are frequently on call. Pressure to make quick and accurate decisions along with the responsibility of performing complex procedures contribute to surgeons' high stress-levels, anxiety and altered empathy level. We aimed to study surgeons' personality and meaning in life at two different centres.
METHODS
General surgeons completed 47 questions. Visual analogous scale-items with controlled internal consistency (Cronbach alpha) coefficients varying from .77 to .85 were used from the following scales: Global Measure of Perceived Stress; Hostility Questionnaire; Jefferson Scale of Physician Empathy; Meaning in Life Questionnaire-SF; Rosenberg Self-Esteem Scale; Spielberger State Anxiety Scale and Quality of Work life Scale. Multiple linear regression analyses, parametric or non-parametric tests were employed when considered adequate.
RESULTS
Fifty-four participants were recruited from 3 different levels of training. Gender differences in Anxiety, Physician Empathy and presence of meaning in life (MIL-P) were revealed. Junior trainees differed from senior trainees and consultants as regards MIL-P, Anxiety, Stress and work-related factors. The surgeons' self-rated self-esteem was work-related. Surgeons' Quality of Work Life was best predicted by Physician Empathy but also their self-rated Self-Esteem contributed significantly to the prediction. Surgeons' MIL-P was significantly predicted by Physician Empathy and State Anxiety.
CONCLUSION
Surgeons' current personality attributes might not apply to all of them. Female surgeons were more empathetic and felt more presence of meaning in life than male surgeons, and men were less anxious than female surgeons. Junior trainees experienced less anxiety than senior trainees but were more stressed than consultants. The most significant predictors of surgeons' personality were their experience of presence of meaning in life along with their level of empathy.

INTRODUCTION
Road crashes present a serious public health issue. Many people are seriously or fatally injured every year in avoidable crashes. While these crashes can have multiple contributing factors, including road design and condition, vehicle design and condition, the environment and human error, the performance of illegal driving behavior, including speeding, may also play a role. The current study aimed to examine the mediating influence that four potential deterrents (perceptions towards enforcement, crash risk, social norms and disapproval, and negative personal/emotional affect) have between the Big Five personality traits (conscientiousness; extraversion; agreeableness; neuroticism; openness) and expectations to speed.
METHODS
A total of 5,108 drivers in Victoria, Australia completed an online survey in 2019. A mediated regression analysis was used to examine pathways in a conceptual model developed for the study.
RESULTS
The results showed that perceptions towards the four potential deterrents examined did mediate the relationship (either completely or partially) between personality and expectations to speed.
CONCLUSIONS
The results of this study suggest that if interventions to deter illegal driving behavior are to be successful, one factor that could be taken into account is the personality traits of drivers who may be at greatest risk of the performance of illegal driving behaviors.

Despite the growing body of research on chronic pain in adults with osteogenesis imperfecta (OI), there is still a lack of comprehensive understanding of the influence of psychological factors on pain experienced by individuals with this condition. This study aims to delve into the correlation between personality traits and various aspects of pain, such as frequency, intensity, appraisal, and coping mechanisms, in a significant sample of adults with OI. Additionally, the investigation seeks to identify whether certain personality profiles may be more susceptible to chronic pain within this specific population. A descriptive cross-sectional study was conducted on a sample of 418 adults diagnosed with OI. Participants completed an online survey that assessed sociodemographic and clinical variables, pain parameters, personality traits, pain appraisal, and coping strategies. Subsequently, descriptive, correlational, cluster and comparative analyses were performed. Up to 83% of the participants reported experiencing pain on a regular basis. Regarding personality dimensions, moderate scores were obtained, with no significant differences compared to the general population. Neuroticism emerged as the trait showing the most robust relationships with the evaluated variables. It positively correlated with pain intensity, frequency, and the perception of pain as threatening (P < .001). Conversely, higher levels of extraversion were associated with a reduction in pain and its threatening perception (P < .001). Finally, the cluster analysis revealed a personality profile that showed greater vulnerability in pain adaptation, characterized by high levels of neuroticism and low levels of extraversion, agreeableness, and conscientiousness. Chronic pain is prevalent in adults with OI. Personality dimensions maintain a significant relationship with this pain, acting as vulnerability or protective factors. Consequently, specific personality profiles are associated with poorer adaptation. Understanding these profiles would allow for a deeper comprehension of the pain experience in adults with OI.

Review
OBJECTIVE
This systematic review sought to summarize comprehensively the research investigating the association between facets of neuroticism and mortality risk.
METHODS
A systematic review of prospective cohort studies utilizing rigorous reporting methods was conducted. Six electronic bibliographic databases, MEDLINE [Ovid], Embase, PsycINFO, CINAHL, Web of Science, and SCOPUS, were searched for eligible studies using keywords encompassing personality traits and mortality. Articles from inception to January 2023 were reviewed. The risk of bias was also assessed.
RESULTS
Six of the 2358 identified studies met the inclusion criteria for extraction. Included studies had 335,715 participants, of whom 3.23% died. Participants ages at baseline ranged from 20 to 102, and 54% were female. Five of the six studies reported statistically significant associations between facets of neuroticism and mortality risk. Several underlying facets were reported to be associated with an increased mortality risk, namely vulnerability, cynicism, pessimistic, anxious, and depressive facets. Inadequacy, and worried-vulnerable were reported as protective. One study reported protective effects for impulsiveness, but this was not observed in a further follow-up study.
CONCLUSIONS
Various facets related to neuroticism are associated with an increased or decreased mortality risk. Encompassing all facets in a broad trait likely masks very important personality-health relations, which later impact longevity. Based on these findings, recommendations and future considerations are discussed.

Characterization of different types of anxiety disorders in relation to structural integration of personality and adverse and protective childhood experiences in psychotherapy outpatients - a cross-sectional study.
BACKGROUND
Current research has emphasized the role of structural integration of personality and childhood experiences for the understanding of anxiety disorders. In this study, we examined the relationship between anxiety disorders (generalized anxiety disorder vs. panic disorder vs. phobic disorders), the level of structural integration of personality, and negative and protective childhood experiences at the beginning of outpatient psychodynamic psychotherapy treatment. Differences were characterized in comparison to patients with no anxiety disorders.
METHODS
The sample included a total of 1646 outpatient psychodynamic psychotherapy treatments, of which 695 treatments included the diagnosis of at least one anxiety disorder. Levels of structural integration of personality were assessed according to the Operationalized Psychodynamic Diagnosis (OPD-2) system. Self-reported negative and protective childhood experiences were examined by using the Questionnaire for the Assessment of Adverse and Protective Childhood Experiences (APC). Associations were tested using single factor ANOVAs.
RESULTS
Patients with anxiety disorders showed lower levels of structural integration of personality and reported more adverse childhood experiences than patients with no anxiety disorders. Regarding the subscales of structural integration of personality, phobic disorders were associated with impaired external communication, whereas for generalized anxiety disorder, an (uncorrected) association with impaired self-regulation was found. Also, generalized anxiety disorder was associated with sexual abuse and other traumatization (accidents etc.) during childhood, while panic disorder and phobic disorders were associated with emotional neglect, abuse, and fewer protective childhood experiences.
CONCLUSIONS
Our findings emphasize the need of considering structural integration of personality and childhood experiences in order to understand and treat various types of anxiety disorders.

INTRODUCTION
Previous research has shown that personality traits and gaming motives are important predictors for explaining regular and disordered gaming. However, the mediating role of gaming motives in the relation between personality traits and video game outcomes (e.g., time spent gaming or disordered gaming) has been scarcely studied and limited cross-national studies have addressed this issue. The present study aimed to examine the direct and indirect effects of the Big Five personality traits on weekly gaming and disordered gaming via gaming motives across seven countries.
METHOD
3540 college student gamers (59.5% women) from the U.S., Canada, Spain, Argentina, Uruguay, South Africa and England completed the online survey. Structural equation modeling was conducted to test models. Multigroup models were employed to test model invariance across countries.
RESULTS
Significant, albeit weak, relations were found between personality traits and gaming outcomes, and were mediated mostly by coping motives in predicting disordered gaming, and by social interaction and recreation (to a lesser extent) motives in predicting weekly gaming. Some minor, yet significant, differences across countries appeared and are discussed in detail.
DISCUSSION
The present findings indicate that the differential interrelations between personality traits, gaming motives, and video gaming outcomes may be generalized in college students across countries.

INTRODUCTION
Cooperation and competition are common in social interactions. It is not clear how individual differences in personality may predict performance strategies under these two contexts. We evaluated whether instructions to play cooperatively and competitively would differentially affect dyads playing a Pong video game. We hypothesized that instructions to play cooperatively would result in lower overall points scored and differences in paddle control kinematics relative to when participants were instructed to play competitively. We also predicted that higher scores in prosociality and Sportspersonship would be related to better performance during cooperative than competitive conditions.
METHODS
Pairs of participants played a Pong video game under cooperative and competitive instructions. During competitive trials, participants were instructed to score more points against one another to win the game. During the cooperative trials, participants were instructed to work together to score as few points against one another as possible. After game play, each participant completed surveys so we could measure their trait prosociality and Sportspersonship.
RESULTS
Condition was a significant predictor of where along the paddle participants hit the ball, which controlled ball exit angles. Specifically, during cooperation participants concentrated ball contacts on the paddle towards the center to produce more consistent rebound angles. We found a significant correlation of Sex and the average points scored by participants during cooperative games, competitive games, and across all trials. Sex was also significantly correlated with paddle kinematics during cooperative games. The overall scores on the prosociality and Sportspersonship surveys were not significantly correlated with the performance outcomes in cooperative and competitive games. The dimension of prosociality assessing empathic concern was significantly correlated with performance outcomes during cooperative video game play.
DISCUSSION
No Sportspersonship survey score was able to predict cooperative or competitive game performance, suggesting that Sportspersonship personality assessments are not reliable predictors of cooperative or competitive behaviors translated to a virtual game setting. Survey items and dimensions probing broader empathic concern may be more effective predictors of cooperative and competitive performance during interactive video game play. Further testing is encouraged to assess the efficacy of prosocial personality traits as predictors of cooperative and competitive video game behavior.

Ethically and socially aversive behaviors have been attributed to several personality traits, including characteristics collectively referred to under the umbrella term of impulsivity. It is an open question, however, whether such characteristics are an integral part of ethically and socially aversive personality. Relying on three large samples (total N = 9854) and implementing longitudinal assessments, the present study provides a comprehensive investigation of the role of impulse and interference control in aversive personality. Based on contemporary conceptualizations of the impulsivity domain, a total of 17 dimensions spanning both self-reports and behavioral tasks are assessed. To represent aversive personality, we consider the D Factor of Personality (D), i.e., the basic disposition shared by all aversive traits. Results indicate that D co-occurs with a deficit in inhibiting the incorrect action when multiple actions are available, a preference for immediate rewards while failing to consider the consequences of one's actions, and maladaptive behavior directed towards regulating strong affect. However, most associations between D and dimensions of impulsivity were small or non-significant, thereby disconfirming the notion that characteristics related to a lack of impulse control are an integral feature of aversive personality in general.

BACKGROUND
Cryptocurrencies are a popular investment tool today. However, some studies highlight the investing behavior of cryptocurrencies similar to pathological gambling. Investing behavior becomes risky when it is not based on proper and adequate analysis and carries the possibility of big losses as well as big gains. For this reason, we aimed to determine the potential risky investor profile by age, gender, personality traits and impulsivity levels.
SUBJECTS AND METHODS
Six hundred and fifty-four cryptocurrencies investors (529 was male, 125 was female, their mean age was 35.6 ± 9.0) participated in this study between June 2022 - August 2022. Participants were administered the Sociodemographic Data Form, the South OAKS Gambling Screen Test - revised (SOGS-r), the Big Five Inventory (BFI-10), and Barratt Impulsiveness Scale-11 (BIS-11).
RESULTS
We found higher neuroticism and impulsivity in possible problematic crypto investors. In addition, extraversion, agreeableness and conscientiousness scores were lower. Additionally, in our regression analyzes we found that younger age and male gender predicted SOGS-r scores. After controlling for age and gender, extraversion negatively and motor impulsivity positively predicted SOGS-r scores.
DISCUSSION
Investing in cryptocurrencies can become a behavioral addiction, similar to pathological gambling. It is important to identify profiles in which investment behavior is risky.
CONCLUSION
Personality traits and impulsivity may have a significant impact on identifying risky crypto investors and in the treatment process.
