Do military decision makers behave as predicted by prospect theory?

Four experiments were conducted to explore the robustness of risky choice framing among military decision makers. In the first experiment the original version of the Asian disease problem was administered. In contrast to Tversky and Kahneman's ( 1981 ) original findings, military decision makers were not influenced by the gain and loss framing. They demonstrated risk‐seeking behavior in both domains. In the second experiment, we administered a military version of the Asian disease problem. We found a significant framing effect, but it was unidirectional: The decision makers were risk seeking in both domains, but significantly more risk seeking in the loss domain. To explore the strength of this risk‐seeking preference, we altered the problem in a third experiment, making the risky alternative 12.5% less attractive than the certain one. Again, we found risk‐seeking behavior in both domains. Finally, we explored reasons for these deviations from prospect theory by comparing the responses of business students and military officers. In this analysis, we observed significantly higher levels of self‐efficacy in the military sample, as compared to the civil sample, and that the self‐efficacy influenced risk seeking only in the military sample. In a post hoc analysis we also found that years of education reduced risk‐seeking preference. Implications and directions for future research are discussed.

Personality,dangerous driving,and involvement in accidents: Testing a contextual mediated model

The present study tested the role of various personality traits in explaining dangerous driving and involvement in accidents, using a contextual mediated model (N = 311). We initially found direct effects of personality traits on dangerous driving indicators (Big-5, Dark Triad, sensation seeking, aggression, and impulsivity). Subsequently, personality variables with predictive power were tested in the mediation model. Indirect effects of anger, psychopathy and sensation seeking on the history of involvement in traffic accidents were found, which was predicted directly by risky driving. The results are discussed based on the characteristics of each trait. Overall, our research replicates and extends previous findings and highlights the importance of psychological evaluations (e.g., personality test) when prospective drivers are applying for a driver license.     

Personality, risky driving and accident involvement among Norwegian drivers

Despite the large body of studies, the role of personality in risk research still remains debatable and unclear. The objective of this study was to identify determinants of road user behaviour and accident involvement with the aim of developing effective accident countermeasures. Examining relationships between personality, risky driving and involvement in accidents can open up the possibility of early identification of those more likely to be involved in accidents. The aim is not to influence personality as such, but to develop measures constructed for specific groups. The results are based on a self-completion questionnaire survey carried out among a sample of Norwegian drivers in year 2000 and 2001 (n=2605). The Norwegian Directorate of Public Roads financed the study. The questionnaire included measures of risky driving, accident involvement, normlessness, sensation-seeking, locus of control and driver anger. Results showed that those who scored high on sensation seeking, normlessness and driver anger reported more frequent risky driving compared to those who scored low on these variables. They were more often involved in both speeding and ignorance of traffic rules. Respondents involved in risk taking-behaviour experienced near-accidents and crashes leading to both injuries and material damage more often than other drivers.     

The influence of the frequency of cannabis use and of the five impulsivity traits on risky driving behaviors among young drivers

Concerns about road safety are at the forefront of discussions given the recent legalization of cannabis in many areas. Some studies have demonstrated that the frequency of cannabis use is a significant predictor of risky driving among young drivers. However, it is difficult to isolate the specific contribution of substance use from the influence of certain individual personality traits such impulsivity. Indeed, impulsivity traits (i.e., positive urgency, negative urgency, lack of premeditation, lack of perseverance, sensation seeking) are also correlated with risky driving. The present study examined the effect of the frequency of cannabis use on risky driving while taking into account the effect of five impulsivity traits. A community sample of 209 young drivers (aged 17–25 years) completed self-report questionnaires about their road behaviors, their cannabis use, and their impulsivity traits. The results showed that the frequency of cannabis use was significantly associated with risky driving beyond the five impulsivity traits measured. Positive urgency was the only impulsivity trait that remained significantly associated with risky driving once all covariates were entered into the model. Moreover, the frequency of cannabis use acted as a mediator in the relationship between sensation seeking and risky driving.     

Parent and child personality characteristics as predictors of negative discipline and externalizing problem behaviour in children

Negative discipline has been linked to childhood externalizing behaviour. However, relatively little attention has been given to the potential effect of individual personality characteristics of children and parents. Using the Five Factor Model, we examined the extent to which parents' and children's personality characteristics were related to parenting and children's externalizing behaviour in a proportional stratified general population sample (N=599) of elementary‐school‐aged children. Based on Patterson's macromodel of parenting, an initial model was built, hypothesizing that the impact of parents' and child's personality dimensions on externalizing problems was fully mediated by negative discipline. Results supported a modified model that added direct pathways between parent and child personality characteristics and externalizing problem behaviour. For the mother data, as well as for the father data, children's Extraversion and Imagination were positively related to children's externalizing problem behaviours. Children's Benevolence and Conscientiousness and parents' Emotional Stability were negatively related to externalizing problem behaviours. For the mother data, maternal Agreeableness was positively related to externalizing problem behaviours too. Copyright © 2003 John Wiley & Sons, Ltd.     

Lay Personality Theories in Interactive Decisions: Strongly Held,Weakly Supported

In interactive decisions, cues to what others will do are important in forming a strategy. Information about others' personalities appears to be potentially valuable for this purpose. We report a series of four studies examining how information about another actor's personality influences people's own choices in interactive decisions. The studies found widespread beliefs that others' personality characteristics are strongly predictive both of broad classes of decision behavior (competition/cooperation, risk‐seeking/risk‐aversion) (Study 1) and of specific choices (Study 2) in single‐agent settings. These beliefs extended to predicting others' choices in interactive decisions (Study 3) and to shaping the predictor's own decisions in interactive play in Chicken and Assurance games (Study 4). Overall, we found extensive evidence that laypeople believe that the personality traits we selected (angry‐hostility, anxiety, assertiveness, excitement‐seeking, and warmth) have substantial effects on behavior in interactive decisions and they act on those beliefs when making their own decisions. The empirical evidence supporting the predictive validity of these traits was, however, quite weak. Copyright © 2014 John Wiley & Sons, Ltd.     

More Than Just Skin Deep? Personality Information Influences Men's Ratings of the Attractiveness of Women's Body Sizes

ABSTRACT

This study examined the influence of personality information on perceptions of the physical attractiveness of a range of female body sizes. A sample of 2,157 male university students were randomly assigned to one of 10 groups in which they received personality information about women they were rating, or a control group in which they received no personality information. Controlling for participants' age and body mass index, results showed no significant between-group differences in the body size that participants found most attractive. However, participants provided with positive personality information perceived a wider range of body sizes as physically attractive compared with the control group, whereas participants provided with negative personality information perceived a narrower range of body sizes as attractive. Correlations showed that participants' own Extraversion was associated with their body size ratings. These results suggest that non-physical cues have an influence on the perception of physical beauty.     

A test of Holland's theory in a population of accountants

The study examined the SDS scales and work attitudes of 1952 Canadian Chartered Accountants (Anglophones and Francophones) and Californian Certified Public Accountants. Combinations of C, E, and S were found the most frequent personality patterns, and they constitute 27.8% of the total population. Scores on these types were positively related to organizational and professional commitments, as well as to vocational satisfaction. The level of congruence was positively correlated with the vocational criteria only in the American sample. The consistency level correlated with professional commitment in the Francophone sample, whereas the differentiation score showed mixed results.     

The sexual sensation seeking scale: reliability and validity within a heterosexual college student sample

The Sexual Sensation Seeking Scale (SSSS; Kalichman & Rompa, 1995) is a measure of the propensity to seek out novel or risky sexual stimulation. This measure has been consistently related to HIV-risk behavior in several different samples of gay men and with behavioral correlates of sexual permissiveness in college students. Five hundred twenty-eight college students completed the SSSS and several other sexuality and personality measures. The results reveal significant gender differences on the SSSS and similar (although stronger among women) patterns of significant correlations with sexually permissive characteristics and behaviors. Furthermore, SSSS scores were more highly correlated with sexual measures, whereas a more general measure of sensation seeking was more highly correlated with general personality measures. We discuss implications for use of the SSSS by sexuality educators and sex therapists.     

The ability to process emotional information predicts loss aversion

On the basis of previous research it was hypothesized that alexithymia is associated with a higher tolerance for losses. This hypothesis is extended to explore whether the putative link between loss aversion and alexithymia remains once traits associated with risk taking (sensation seeking) and broad based personality traits (the Big 5) are controlled. Participants (N = 260) completed indices of alexithymia, sensation seeking and the Big 5 and both a riskless (endowment effect) and risky (lottery task) measure of loss aversion. It was found that the higher the alexithymia score the lower the loss aversion for both riskless and risky decisions even when sex, sensation seeking and the Big 5 are taken into account. The implications for this finding are discussed in the light of a neurological explanation of the relationship between alexithymia and loss aversion.     

Risk and Prisoner's Dilemma: A Reinterpretation of Coombs' Re‐parameterization

We propose a model to measure risk in a prisoner's dilemma based on Coombs' (1973) re‐parameterization of the game as an individual risk decision‐making task that chooses between a gamble of cooperation and another gamble of defection. Specifically, we propose an index, r, to represent the risk associated with cooperation relative to defection. In conjunction with Rapoport's (1967) index of cooperation (K), our formulation of risk allows us to construct games that vary in risk (as indexed by r) while controlling for cooperativeness (as indexed by K). Following utility analysis that models risk seeking as a convex utility function and risk averse as a concave function, we predict that risk‐seeking people cooperate more in games that the cooperation choice is more risky, whereas risk‐averse people cooperate more in games that the cooperation choice is less risky. In the three studies that we varied game parameters, used different measures of risk orientation and prosocial orientation and used different experimental procedures, we found robust results supporting our predictions. Theoretical analysis of our formulation further suggests that risk and cooperativeness of a prisoner's dilemma game is not entirely independent. Games that have a higher cooperativeness index are necessarily more risky. Copyright © 2011 John Wiley & Sons, Ltd.     

Association between the Five Factor personality traits and perceived stress: is the effect mediated by general self-efficacy?

Abstract

Ill-health resulting from chronic stress is influenced by personality traits leading to different ways of appraising and coping with life's daily hassles. Using a large population sample the study aimed to investigate possible associations between perceived stress and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and to explore the role of general self-efficacy (GSE). A population-based cross-sectional study was conducted at the Research Centre for Prevention and Health, Denmark, in 2006–2008. Men and women (N=3471) aged 18–69, were randomly sampled in the suburbs of Copenhagen. We used the NEO Five-Factor Inventory (NEO-FFI), Cohen's Perceived Stress Scale and the General Self-Efficacy Scale. Negative associations were found between perceived stress and extroversion, conscientiousness, agreeableness, and openness – the latter initially non-significant – whilst neuroticism had a positive association. The associations with agreeableness and openness became positive and significant, respectively, when GSE was included. All five personality-stress models were mediated by GSE, with extroversion and conscientiousness having the strongest mediating effect. The strongest stress-association was found for neuroticism. GSE was shown to change the impact and interpretation of the personality dimensions on perceived stress. These results indicate that GSE is an important factor to consider in the link between personality and perceived stress.     

Dimensional Personality Traits Broadly and Selectively Associated with Normative Externalizing Behavior

This study aimed to distinguish personality traits that are widely associated with several types of externalizing behaviors from personality traits that are more selectively associated with one or only a few specific types of externalizing behavior. A wide range of externalizing behaviors (e.g. alcohol and drug use, risky driving, aggressive acts, sexual promiscuity and relationship infidelity, academic misconduct) typical among an undergraduate population (N?=?257) were examined along with a range of personality traits measured using the Section III personality model for the DSM-5. We found that externalizing behavior was best associated with the domain level trait Antagonism and, to a lesser degree, Disinhibition. Antagonism’s association with problematic behavior was primarily accounted for by the facet trait Deceitfulness. Deceitfulness was found to be associated with a wide range of behaviors including relationship infidelity, theft, aggressive acts, and drug and alcohol use. Associations between Disinhibition and problem behavior, especially risky driving and poor work or school performance, were best accounted for by the Irresponsibility facet, as opposed to the Impulsivity or Distractibility facet traits. This comprehensive multivariate approach is important for a more complete understanding of the complex relationship that exists between personality traits and externalizing behavior. A better understanding of factors precipitating externalizing behavior could ultimately lead to an increased ability to target interventions to individuals most susceptible to engage in problematic behavior.     

Assessing Level of Personality Organization With the Psychodiagnostic Chart: A Validity Study

Heterogeneity within diagnostic types and comorbidity across diagnostic groups render a specific personality disorder anything but specific, leading researchers and clinicians to increasingly focus on the general severity of personality pathology. Personality pathology severity is reflected in one's level of personality organization (LPO) and research has demonstrated that LPO is a significant predictor of treatment response. This investigation examined the reliability and validity of the Psychodiagnostic Chart (PDC) in assessing the LPO dimension of the Psychodynamic Diagnostic Manual (PDM; PDM Task Force, 2006). Among a sample of 88 urban-dwelling women seeking primary medical care, the LPO dimension of the PDC received fair to good interrater reliability among 6 psychodynamic psychologists. Convergent validity was demonstrated with contrast analysis and individual correlations that yielded statistically significant associations between LPO scores and conceptually related psychodynamic variables (e.g., defensive functioning, object relations) and self-reported personality pathology scores. Support for discriminant validity was limited by the modest power associated with the sample size. Exploratory analyses examining LPO scores and measures of physical health and intimate partner violence were conducted. Our results supported the reliability, validity, and practical use of the LPO dimension of the PDC.     

Adaptive and maladaptive personality traits as predictors of violent and nonviolent offending behavior in men and women

The aim of this study was to assess both violent and nonviolent offending behavior in a single, mixed‐sex population. The rationale for this is that the two types of offending are usually researched separately, despite evidence that they overlap. A comprehensive measure of general violence, intimate partner violence (IPV), and nonviolent offending behavior was administered to 116 men and 181 women, together with measures of personality and personality disorder (PD) traits, to investigate whether predictors of violent and nonviolent offending were similar or different for men and women. Men were found to perpetrate higher levels of general violence and nonviolent offenses than women, but women perpetrated significantly more IPV than men. Cluster B PD traits predicted all three offense types for women and also men's general violence and nonviolent offending. Women's general violence and men's non‐violence also had one unique risk factor each, low agreeableness, and low conscientiousness, respectively. The main difference was for IPV, where men's IPV was predicted by cluster A PD traits, indicating that men's and women's risk factors for IPV may be different, although their risk factors for the other offense types were fairly consistent.

Risk-taking and impulsive personality traits in proficient downhill sports enthusiasts

Although past studies have examined how personality traits may motivate participation in high-risk sports, few previous studies have examined impulsive personality correlates with risk-taking within a group of sports enthusiasts. We examined relationships between measures of personality and risk-taking on the slopes as measured by a sport-specific Sensation Seeking Scale in a sample of proficient-level skiers and snowboarders (N = 123, 61% male). Significant correlations were found between risk-taking and multiple traits including Reward Sensitivity, Punishment Sensitivity, and Sensation Seeking, implying that some traits that motivate participation in high-risk sports also lead to more risky behavior while participating in said sports. Rash Impulsivity, though not found to distinguish participants from non-participants in previous studies, did correlate with risk-taking behavior on the slopes. The results of this study show that while some aspects of impulsive personality may motivate risky sport participation, other traits may be related to risky behavior once engaged in the sport.     

The state of motherhood among professional women

Faculty women at Northwestern University were studied. The focus was on their rate of childlessness and attitude toward having children. The 151 subjects were classified into two age groups: women of childbearing age — under 40 — and women much less likely to have children — 40 and over. Although women ever married in the professional sample had a higher rate of childlessness than women ever married in the general population in all age groups, there seemed to be a trend toward permanent childlessness among younger professional women: Their rate of childlessness (67%) is much higher than that of the older professionals (22%) or the younger women in the general population. Based on additional qualitative and quantitative data, a possible explanation for the younger professional women's behavior seems to be that they are not confident that they can successfully combine motherhood and career. Possible implications of this phenomenon are discussed.     

Are the sources of interest the same for everyone? Using multilevel mixture models to explore individual differences in appraisal structures

How does personality influence the relationship between appraisals and emotions? Recent research suggests individual differences in appraisal structures: people may differ in an emotion's appraisal pattern. We explored individual differences in interest's appraisal structure, assessed as the within-person covariance of appraisals with interest. People viewed images of abstract visual art and provided ratings of interest and of interest's appraisals (novelty–complexity and coping potential) for each picture. A multilevel mixture model found two between-person classes that reflected distinct within-person appraisal styles. For people in the larger class (68%), the novelty–complexity appraisal had a stronger effect on interest; for people in the smaller class (32%), the coping potential appraisal had a stronger effect. People in the larger class were significantly higher in appetitive traits related to novelty seeking (e.g., sensation seeking, openness to experience, and trait curiosity), suggesting that the appraisal classes have substantive meaning. We conclude by discussing the value of within-person mixture models for the study of personality and appraisal.     

Personality of male Anglican clergy in England: Revisited using the 16PF5

Cattell's latest version of the 16PF (16PF5) was completed by a random sample of 580 male Anglican clergy whose names and addresses were provided by the Church Commissioners' payroll. These data demonstrate a distinctive profile for clergy that differs significantly from that of the general male population on 12 personality factors. In addition, these data indicate agreement on seven scales, and disagreement on eight scales, between the profiles of male clergy as measured on the old study using the 16PF4 and this study using the new version.     

Is it possible to be too happy? Happiness,personality, and psychopathology

The types of relationship between happiness, personality and psychopatholgy are assessed in an available sample (n = 321, adults, both sexes). Empirical results from two happiness scales and two questionnaires, one of personality (NEO-PI-R) and other of personality disorders (Loranger's scale), do not confirm the Diener's threshold hypothesis, that makes a distinction between optimum and maximum happiness; or the Seligman's supposition, that assumes that happiness has no limits; The main results are: a) negative affect (Neuroticism) is negatively related to happiness across its full range; b) Extraversion and Openness to experience are positively related to happiness across its full range; c) in the rest of the basic personality factors, relationships are not linear, though not in the sense anticipated by Diener, and d) in personality disorders, the tendencies observed diversify according to the type of disorder, and the type of happiness factor. On most occasions, the close relationship between personality disorders and the Neuroticism dimension is verified in a consistent manner. These results are discussed within the context of clinical psychology, and the general theory about happiness.
