Extraversion, neuroticism, psychoticism and recreational choice

Introversion and High Spatial Ability Is Associated With Origami Proficiency

This study examined the relationship between origami performance, personality traits, and spatial ability. The researchers asked 43 Japanese university students (19 women and 24 men) to fold three models of origami (paper folding). Their performance was assessed by the number of successes in correctly folding the paper to make the models. They also answered the personality inventory NEO-FFI and completed the block-design test of the Wechsler Adult Intelligence Scale IV, which measures the spatial ability of people. The results showed that although origami performance demonstrated no significant relation with neuroticism, openness to experience, agreeableness, or conscientiousness, it improved as introversion tendency and spatial ability increased. There were no differences based on sex in origami performance. The findings suggest that performing origami requires spatial ability, which supports the view that origami is a potential educational material for training and enhancing spatial ability, and that introversion is advantageous to origami performance.

Effects of Three Levels of Green Exercise, Physical and Social Environments, Personality Traits, Physical Activity, and Engagement with Nature on Emotions and Attention

The current study examined the effects of the three levels of green exercise on people’s psychological health using a randomized trial with a pretest and posttest design and further explored which variables of the physical environment (thermal comfort, noise, and air pollution), social environment (the number of companions and crowdedness), personality traits, physical activity (intensity and frequency), and engagement with nature may help explain experiences during the three levels of green exercise using a cross-sectional approach. Field studies were conducted to test the study’s hypotheses. The participants were 95 students from a technology university in Taiwan. The experiment comprised a 15-min green exercise in a park. No significant differences were found in emotions and attention between the three levels of green exercise. However, a 15-min green exercise of any level significantly improved emotions and attention. Furthermore, fatigue was significantly and negatively associated with daily transportation-related physical activity, agreeableness, and engagement with nature. Moreover, the total mood disturbance was significantly and negatively associated with engagement with nature and daily transportation-related physical activity. The degree of engagement with nature played a pivotal role in green exercise. This study provided the evidence that quantified engagement with nature is beneficial for quantified psychological health for the first time.

The Association Between Personality Traits and eSports Performance

This study focuses on the relationship between personality traits, derived from the Big Five model, and performance in the competitive electronic sports (eSports) video game League of Legends (LoL). Data were gathered from 206 LoL players of various in-game success levels, as measured by their position within the competitive hierarchy (division) of the video game. The NEO-Five Factor Inventory (NEO-FFI) questionnaire was used to measure personality traits within the gathered sample, which was divided into two groups of higher and lower ranked players. The results indicate that players who reach higher divisions in LoL tend to be less extraverted, less agreeable, but more open to experience. This is one of the few reported links between eSports performance and personality traits, in what is still a nascent yet rapidly developing research topic. The results are discussed within the context of available knowledge on personality and traditional competitive sports performance.

Role of self-reported individual differences in preference for and tolerance of exercise intensity in fitness testing performance

Performance in fitness tests could depend on factors beyond the bioenergetic and skeletomuscular systems, such as individual differences in preference for and tolerance of different levels of exercise-induced somatosensory stimulation. Although such individual-difference variables could play a role in exercise testing and prescription, they have been understudied. The purpose of these studies was to examine the relationships of self-reported preference for and tolerance of exercise intensity with performance in fitness tests. Participants in study I were 516 men and women volunteers from a campus community, and participants in study II were 42 men recruit firefighters undergoing a 6-week training program. Both the Preference and Tolerance scores exhibited significant relationships with performance in several fitness tests and with body composition and physical activity participation. Preference and Tolerance did not change after the training program in study II, despite improvements in objective and perceived fitness, supporting their conceptualization as dispositional traits. Preference and Tolerance scores could be useful not only in ameliorating the current understanding of the determinants of physical performance, but also in personalizing exercise prescriptions and, thus, delivering exercise experiences that are more pleasant, tolerable, and sustainable.

The Moderating Effect of Personality Type on the Relationship between Leisure Activity and Executive Control in Older Adults

We examined the moderating effect of personality on the association between leisure activities and executive control in healthy community-dwelling older adults. We found two distinct personality typologies: individuals with a Resilient personality were characterized by emotional stability and self-confidence; whereas, those who resembled an Overcontrolled personality tended to be introverted, but also low on neuroticism. Resilient individuals were more likely than Overcontrolled individuals to demonstrate higher executive function and attention as a result of participation in mental activities. These results suggest that personality might be important to include in studies that test the efficacy of activity interventions for improving cognition.

THE RELATIONSHIP BETWEEN EXTROVERSION AND LEISURE MOTIVATION: EVIDENCE FROM FITNESS CENTER PARTICIPATION

In this study the relationship between extroversion and leisure motivation in Taiwanese fitness center members was examined. A systematic sampling (one out of ten entering the fitness center) produced 424 usable questionnaires for the final data analysis. The findings reveal that extroversion is positively correlated with the four leisure motivation dimensions: Intellectual, Social, Competence-mastery and Stimulus-avoidance. We therefore conclude that extroverts will be highly motivated to attend fitness centers.

Neuroticism, extraversion, and mortality in a defined population of older persons

OBJECTIVE

The objective of this study was to test the association of the personality traits of neuroticism and extraversion with risk of death in old age.

METHODS

A census was taken of a geographically defined urban community in Chicago, and those aged 65 years or older were invited to participate in an in-home interview; 6158 (79% of those eligible) did so. The interview included brief measures of neuroticism and extraversion, medical history, and questions about current participation in cognitive, social, and physical activities. Vital status was subsequently monitored. The association of each trait with risk of death was examined in a series of accelerated failure-time models that controlled for age, sex, race, and education.

RESULTS

During a mean of more than 6 years of observation, 2430 persons (39.5%) died. A high level of neuroticism (score = 27; 90th percentile) was associated with a 33% increase in risk of death compared with a low level of neuroticism (score = 9; 10th percentile). A high level of extraversion (score = 33; 90th percentile) was associated with a 21% decrease in risk of death compared with a low level (score = 18; 10th percentile). Adjustment for medical conditions and health-related variables did not substantially affect results, but adjusting for baseline levels of cognitive, social, and physical activity reduced the association of both traits with mortality.

CONCLUSIONS

The results suggest that higher extraversion and lower neuroticism are associated with reduced risk of mortality in old age and that these associations are mediated in part by personality-related patterns of cognitive, social, and physical activity.

Conscientiousness and health-related behaviors: a meta-analysis of the leading behavioral contributors to mortality

Previous research has established conscientiousness as a predictor of longevity (H. S. Friedman et al., 1993; L. R. Martin & H. S. Friedman, 2000). To better understand this relationship, the authors conducted a meta-analysis of conscientiousness-related traits and the leading behavioral contributors to mortality in the United States (tobacco use, diet and activity patterns, excessive alcohol use, violence, risky sexual behavior, risky driving, suicide, and drug use). Data sources were located by combining conscientiousness-related terms and relevant health-related behavior terms in database searches as well as by retrieving dissertations and requesting unpublished data from electronic mailing lists. The resulting database contained 194 studies that were quantitatively synthesized. Results showed that conscientiousness-related traits were negatively related to all risky health-related behaviors and positively related to all beneficial health-related behaviors. This study demonstrates the importance of conscientiousness' contribution to the health process through its relationship to health-related behaviors.

Competition and cooperation in the five-factor model: individual differences in achievement orientation

The authors investigated the relationship between basic achievement orientations of competition and cooperation and the five-factor model of personality as measured by the Revised NEO Personality Inventory (NEO-PI-R; P. T. Costa & R. R. McCrae, 1992). They examined 2 types of competition: hypercompetition (R. M. Ryckman, B. Thornton, & J. C. Butler, 1994) and personal development competition (R. M. Ryckman, M. Hammer, L. M. Kaczor, & J. A. Gold, 1996), as conceptualized by K. Horney (1937). In a sample of 251 young adults, 14% to 38% of the variance in achievement orientations was collectively predicted by NEO-PI-R domain scales. Of NEO-PI-R predictors, Agreeableness was most important in characterizing differences between various achievement orientations; Agreeableness was negatively related to hypercompetition, positively related to cooperation, and unrelated to personal development competition. Extraversion was positively related to both cooperation and personal development competition but was unrelated to hypercompetition. In contrast, Openness and Conscientiousness were least helpful in differentiating among achievement orientations. These findings support the useful application of the NEO-PI-R in achievement research and highlight competition and cooperation as interpersonally laden achievement orientations.
