What is personality? Two myths and a definition

This article addresses the longstanding problem that the field of personality psychology remains in need of a consensus formulation of its core subject matter, that of the nature of “personality” itself. Part 1 of the article presents some reminders about the traditional pre-empirical status of concepts in science. Part 2 introduces and calls into question two widely accepted but nonetheless questionable propositions about the nature of personality: (a) that the term refers to an underlying causal entity within a person, and (b) that the study of personality is the study of the whole person. Part 3 presents a definition of “personality”, discussion elaborating and clarifying this definition, and an explication of the ways in which it differs from previous definitions. Part 4 discusses some benefits that accrue both to having a consensus definition in general, and to acceptance of the present definition in particular.     

The value(s) of information on social network sites: The role of user personality traits

PurposeThe present research examines the relationship between personality of social network site (SNS) users and the perceived value of the information they seek. Building on the Reasoned Action Approach, personality is conceptualized as a background factor influencing people's attitude towards the information they search for on SNS.Design/methodology/approachData were collected using a face-to-face survey among Facebook users (n = 311). Personality traits were assessed based on the Big Five dimensions. Statistical analyses estimate the effects of personality traits on the various values of the information sought on SNS. A three-step procedure was followed to standardize the independent variables and create interaction variables for the moderation test.FindingsThe results support the predictions that certain personality traits (e.g., conscientiousness and extraversion), as described by the FFM framework, are related to particular facets of information value (economic value and social value respectively). The effect of personality was moderated by participants’ Facebook usage intensity. Usage intensity dampens the relationship between agreeableness and functional value of information, and strengthens the negative relationship between openness-to-experience and psychological value of information.Practical implicationsThe personality-information value relationships found can help social media practitioners and marketers shape the content and appeal of the messages communicated to their audience on SNS, and tailor marketer-customer interactions in an engaging way.Originality/valueThe present research contributes to understanding the pivotal role of personality in evaluating the information people seek on social networks. It also adds to the literature regarding FFM and social media usage by supporting the notion that the Big Five personality traits predict value aspects of information that people pursue in the course of search behavior on Facebook.Article classificationResearch paper.     

Factors underpinning unsafe driving: A systematic literature review of car drivers

ObjectivesThe purpose was to provide a systematic review of the literature related to the personality and well-being of social, domestic, pleasure and commuting (SDP&C) car drivers.MethodsThe following databases were searched: PsychINFO (PsychNET), Scopus (Elsevier), Web of Science (Social Sciences Index; WoS), ORCA (Online research at Cardiff University), Science Direct (Elsevier), Taylor and Francis Online, and PubMed. Grey literature was sourced using the Transport Research International Database (TRID) as well as conference proceedings of the Human Factors and Ergonomics Society and Driver Assessment. In parallel, an internet search of Google Scholar was undertaken. Two researchers reviewed papers suitable for inclusion. Eligible papers were those published in the English language, during the last decade; the latter to allow for a more contemporary appraisal of the literature. The search yielded thirty peer reviewed articles and ten reports relevant to the personality and well-being of SDP&C road users.ResultsThe findings show that anxiety, stress and depression were predictive of unfavourable driving outcomes (e.g. risk-taking, aggression, poor driving behaviour.) Further, driving discourtesy by others was found to not only induce stress reactions in drivers, but also led to riskier driving practice, such as deliberately engaging in intimidating driving behaviour. Negative personality traits were related with negative driving behaviours, whilst higher levels of well-being and life satisfaction appear to safeguard drivers against deliberate driving violations. There was a dearth of literature focusing on UK drivers, as well as research examining the impact of driving itself on the well-being of the driver.ConclusionsFurther longitudinal, multivariate research is required to examine all well-being/personality predictors, whilst controlling for established predictors (such as fatigue) such that the factors underpinning unsafe driving behaviour (in isolation and in combination) may be revealed.     

Sleep: A pathway linking personality to mortality risk

Personality and sleep predict longevity; however, no investigation has tested whether sleep mediates this association. Thus, we tested this effect across a 20-year follow-up (N = 3759) in the Midlife Development in the United States cohort (baseline M_age = 47.15) using proportional hazards in a structural equation modeling framework. Lower conscientiousness predicted increased death risk via the direct, indirect, and total effect of quadratic sleep duration. Although there were no other direct personality-mortality effects, higher neuroticism and agreeableness and lower conscientiousness predicted increased death risk via the joint indirect effects of quadratic sleep duration and higher daytime dysfunction. Lower extraversion predicted increased mortality risk via the indirect effect of daytime dysfunction. Our findings have implications for personality-based health interventions.     

Bayesian inferences about the self (and others): A review

Viewing the brain as an organ of approximate Bayesian inference can help us understand how it represents the self. We suggest that inferred representations of the self have a normative function: to predict and optimise the likely outcomes of social interactions. Technically, we cast this predict-and-optimise as maximising the chance of favourable outcomes through active inference. Here the utility of outcomes can be conceptualised as prior beliefs about final states. Actions based on interpersonal representations can therefore be understood as minimising surprise – under the prior belief that one will end up in states with high utility. Interpersonal representations thus serve to render interactions more predictable, while the affective valence of interpersonal inference renders self-perception evaluative. Distortions of self-representation contribute to major psychiatric disorders such as depression, personality disorder and paranoia. The approach we review may therefore operationalise the study of interpersonal representations in pathological states.     

Conceptual ambiguities and measurement issues in sensory processing sensitivity

The aim of the article is (1) to critically discuss Sensory Processing Sensitivity (SPS) in light of personality theories and (2) to examine the validity of the only available measure of SPS, the Highly Sensitive Person Scale (HSPS). Study 1 (N = 289) examines the relations of the HSPS with facets of the Big Five. In Study 2 (N = 226), the HSPS’ relation to emotion recognition ability is estimated after controlling for the Big Five. In contrast to previous studies, these relationships are estimated at the level of latent variables. Our data suggest that SPS highly overlaps with established personality traits, and its relation with emotion recognition ability can be fully explained by Neuroticism and Openness to Experience.     

Psychopathy,charisma, and success: A moderation modeling approach to successful psychopathy

Psychopathic traits are associated with negative outcomes; however, they have also been associated with adaptive outcomes (e.g., corporate success, etc.). We tested the Moderated-Expression Model of psychopathy in a sample of community adults (N = 315; 50.8% female; 22–65 years) utilizing a battery of self-report measures (Self-Report Psychopathy Scale; Triarchic Psychopathy Measure; Conger & Kanungo Scale of Charismatic Leadership; General Charisma Inventory; Evading Detection/Punishment; and Occupational Success). The effect of psychopathic traits on evading detection and punishment (not occupational success) was moderated by leadership (and to a lesser extent, general) charisma, net of the effects of pathological narcissism and several other covariates. These results support the Moderated-Expression Model and warrant further research on the associations among psychopathy, charisma, and success.     

If you’re funny and you know it: Personality,gender, and people’s ratings of their attempts at humor

In seven studies (n = 1133), adults tried to create funny ideas and then rated the funniness of their responses, which were also independently rated by judges. In contrast to the common “funnier than average” effect found for global self-ratings, people were relatively modest and self-critical about their specific ideas. Extraversion (r = 0.12 [0.07, 0.18], k = 7) and openness to experience (r = 0.09 [0.03, 0.15], k = 7) predicted rating one’s responses as funnier; women rated their responses as less funny (d = −0.28 [−0.37, −0.19], k = 7). The within-person correlation between self and judge ratings was small but significant (r = 0.13 [0.07, 0.19], k = 7), so people had some insight into their ideas’ funniness.     

Voluntary decision-making in addiction: A comprehensive review of existing measurement tools

The notion of voluntariness, notably the inability to refrain from using an addictive substance, is central to addiction. This review examines different constructs measuring voluntariness in the context of drug addiction. We found 117 articles featuring 123 distinct scales for 11 of the 16 constructs initially searched. Self-efficacy was by far the construct with most scales. Most scales were not specifically developed with samples of people with addictions. From a methodological standpoint, current literature jeopardizes the validity of generalizations about how voluntariness functions and is measured in people with and without a drug addiction. From the standpoint of social psychology, the study of voluntariness remains anchored in an individualistic orientation to the study of cognition and behavior, thus calling for greater crosstalk between psychology subspecialties.
