Conscious knowledge influences decision‐making differently in substance abusers with and without co‐morbid antisocial personality disorder

Decision‐making impairment, as measured by the Iowa Gambling Task (IGT), is a consistent finding among individuals with substance use disorder (SUD). We studied how this impairment is influenced by co‐morbid antisocial personality disorder (ASPD) and conscious knowledge of the task. Three groups were investigated: SUD individuals without co‐morbid ASPD (n = 30), SUD individuals with co‐morbid ASPD (n = 16), and healthy controls (n = 17). Both SUD and SUD+ASPD participants had poor overall IGT performance. A block‐by‐block analysis revealed that SUD participants exhibited slow but steady improvement across the IGT, whereas SUD+ASPD participants exhibited initial normal improvement, but dropped off during the last 40 trials. Conscious knowledge of the task was significantly correlated to performance for controls and SUD participants, but not for SUD+ASPD participants. Our findings suggest that decision‐making proceeds differently in SUD and SUD+ASPD individuals due to differences in acquisition and application of conscious knowledge.     

The relation between antisocial personality and the perceived ability to deceive

The current study investigated relations between the perceived ability to deceive and the Dark Triad personality traits in two samples. In study 1, the sample consisted of 1074 participants (329 male, 745 female) aged 17–71 years (M = 22.96, SD = 6.92). Participants completed the perceived ability to deceive scale, in which they were asked to estimate the percentage of people who are worse at lying than they are in a number of situations. Participants also completed the Short-D3 – a measure of the Dark Triad personality traits. As expected, correlational analyses demonstrated that Machiavellianism was most highly correlated with the perceived ability to deceive (r = .41), followed by psychopathy (r = .35), and narcissism (r = .33). These findings were replicated in study 2, which consisted of 1448 undergraduate students (498 males, 947 females, 3 other), aged 18–43 (M = 18.35, SD = 1.77). Study 2 also investigated the association of the Dark Triad and perceived ability to deceive with dimensions of the Big Five model of personality. Implications are discussed.     

J.P. Rushton’s contributions to the study of altruism

This essay describes Rushton’s work on altruism over the past 40 years. During his academic career, he changed his theoretical approach from social learning theory to trait theory to sociobiology. My essay includes five sections. The first gives an overview of Rushton’s work on altruism. The second reviews his early work based on social learning theory. His laboratory and naturalistic experiments led him to conclude that altruism could be increased by exposure to models exemplifying the behavior, and that, once engaged in, the behavior could be durable over months and generalizable across situations. The third section discusses his work on the genetic foundation of altruism with social biology including his twin studies of prosocial behaviors using different age groups of both western and Asian samples. He concluded that about 50% of the variance in prosocial behaviors is heritable. The fourth section will describe altruism as part of the general factor of personality, the apex of the personality hierarchy. The last section summarizes my review of Rushton’s work on altruism.     

The influence of negative oriented personality traits on the effects of wind turbine noise

Concern about invisible environmental agents from new technologies, such as radiation, radio-waves, and odours, have been shown to act as a trigger for reports of ill health. However, recently, it has been suggested that wind turbines – an archetypal green technology, are a new culprit in explanations of medically unexplained non-specific symptoms (NSS): the so-called Wind Turbine Syndrome ( Pierpont, 2009). The current study assesses the effect of negative orientated personality (NOP) traits (Neuroticism, Negative Affectivity and Frustration Intolerance) on the relationship between both actual and perceived noise on NSS. All households near ten small and micro wind turbines in two UK cities completed measures of perceived turbine noise, Neuroticism, Negative Affectivity, Frustration Intolerance, attitude to wind turbines, and NSS (response N = 138). Actual turbine noise level for each household was also calculated. There was no evidence for the effect of calculated actual noise on NSS. The relationship between perceived noise and NSS was only found for individuals high in NOP traits the key role of individual differences in the link between perceived (but not actual) environmental characteristics and symptom reporting. This is the first study to show this effect in relation to a so called ‘green technology’.     

Gender-linked personality and mental health: The role of trait emotional intelligence

The present study examined the role of the emotion-related personality dimension, or trait emotional intelligence (EI), in the relationship between gender-linked personality (GLP) traits and internalizing mental health difficulties (IMHDs). GLP traits were measured as Agency and Communion, due to conceptual advantages over other semantic representations (e.g., masculinity, femininity) in the literature. IMHDs as the outcome variable were conceptualized as a latent composite of anxiety, stress, and emotion-oriented coping. A moderate relationship between Agency and IMHDs was fully mediated by trait EI. Trait EI also divided an overall non-significant effect of Communion on IMHDs into an indirect, protective effect via trait EI and a direct, adverse effect. The results suggest that Agency and Communion subsume different sets of trait EI facets, which may account for much of the differential protective effects of these GLP traits on IMHDs. Discussion focuses on implications of the results for sex differences in mental health.     

The general factor of personality: What lies beyond?—II

What remains of the covariance of personality traits after a general factor of personality (GFP) is removed? An earlier analysis based on a US adult community sample was extended to five additional samples, ranging from 739 to 2914 late-adolescent or adult individuals who had completed various personality questionnaires in twin and adoption studies. For the most part, the GFPs were similar. Most of the data sets revealed an additional Conscientiousness/conformity factor, but beyond that there was considerable variation across samples in the supplemental factors obtained.     

The impact of “non-targeted traits” on personality test faking,hiring, and workplace deviance

Evidence suggests that job applicants often “fake” on pre-employment personality tests by attempting to portray an exceedingly desirable impression in order to improve the likelihood of being selected. In the current research we shed light on the personality characteristics of those individuals who seem most likely to engage in faking. We refer to these personality variables as non-targeted traits when they are not directly targeted by the organization’s pre-employment personality test. These traits, however, may have an influence on targeted scores used for employment decision making through their effect on faking. Findings suggest that individuals will be more likely to be hired if they are low on non-targeted traits including Honesty–Humility, Integrity, and Morality, and high on Risk Taking. Such individuals also reported higher levels of workplace deviance in their current jobs. Thus, it seems that individuals low on Honesty–Humility, Integrity, and Morality, and individuals high on Risk Taking, may be most likely to engage in personality test faking, be hired, and participate in workplace deviant behaviors if these traits are not directly targeted in selection.     

Between you and God,where is the general factor of personality? Exploring personality-religion relationships in a Muslim context

Personality-religiosity links were studied in a Muslim population. Agreeableness and Conscientiousness were generally the strongest correlates of religiousness. Evidence for the general factor of personality (GFP) was found in analyses of correlations among scores on the Big Five, in four studies (total N = 1000). Also, a GFP was positively correlated with gratitude to God, interest in religion, intrinsic religiosity and extrinsic-personal religiosity, but not extrinsic-social religiosity. Results demonstrated cross-cultural consistency of the GFP, and its relationship with a variety of religious constructs.     

Examining mindfulness and psychological inflexibility within the framework of Big Five personality

Psychological inflexibility and mindfulness represent two constructs that have garnered a great deal of interest in recent years as central components in the conceptualization of many new cognitive and behavioral therapies. Nonetheless, though theoretically related, relatively little is known regarding associations between these two constructs and consensus models of trait personality such as the Big Five. The current study therefore aimed to more fully elucidate associations among these three domains within a relatively large, diverse undergraduate sample (N = 429). Mindfulness was negatively associated with Neuroticism and positively associated with Conscientiousness while psychological inflexibility was positively associated with Neuroticism and negatively associated with Conscientiousness. Further, while Conscientiousness evidenced the strongest contribution to mindfulness, Neuroticism evidenced the strongest contribution to psychological inflexibility. Better elucidating how psychological inflexibility and mindfulness differentially relate to Big Five personality traits expands the nomological network surrounding these constructs and begins to reveal common processes underlying psychopathology and health behaviors.
