A personality profile of Mount Everest climbers

The Eysenck Personality Questionnaire-Revised was administered to a group of climbers (N=39) who were attempting to summit Mount Everest. The personality profiles for these climbers were characterized by higher scores on the Extraversion (sociability) and Psychoticism (toughmindedness) scales and lower scores on the Neuroticism (anxiety) scales than for the normative sample. This profile is consistent with the pattern typically observed for athletes and notably for higher achieving athletes.     

Psychoticism and attentional flexibility

In three separate experiments, we tested the hypothesis that a systematic relationship between psychoticism (P) and visual selective attention is infrequently observed because the tasks typically used to test individual differences in efficiency of attentional mechanisms do not entail attentional flexibility. We manipulated the selection rule of the computerized divided visual attention (DIVA) task to be either (a) a predictable, or (b) a random manner, and a secondary task was added to check the quality of high P scorers’ performance in an interference condition; and we also introduced breaks between DIVA tasks to allow for cue utilization. Results revealed that low P scorers outperformed high P scorers in the regular selection rule alternation condition (cue utilization possible), whereas high P scorers performed better in random alternation condition – high P scorers also showed performance superiority in the dual task condition unless stimuli presentation was speeded up. Thus, P does not necessarily impair attentional performance; indeed, our data point to performance advantages of high P, especially attentional efficiency in tasks requiring small demands of attentional control.     

Personality and accident liability: are extraversion, neuroticism and psychoticism related to traffic and occupational fatalities?

The aim of the present study was to investigate the relationship between extraversion, neuroticism and psychoticism, and road traffic fatalities in a data set of 34 nations. In addition to traffic fatalities per 100,000 vehicles, work-related fatalities were included in the study. Results showed that extraversion had a positive relation to the number of traffic fatalities whereas neuroticism correlated negatively with road fatalities. Occupational fatalities were strongly related to deaths on the roads but not to personality dimensions. Countries with high extraversion scores had more traffic fatalities than countries with moderate or low extraversion scores. The need for well-designed studies investigating the link between personality factors and traffic accident liability via driver behaviour was expressed.     

Psychometric appraisal of Eysenck's revised Psychoticism scale: a cross-cultural study

Psychometric characteristics of Eysenck's revised P scale were studied in a cross-cultural research. The Spanish version of the Eysenck Personality Questionnaire-Revised (EPQ-R) was administered to a Spanish sample of 527 males and 583 females. Maximum-likelihood factor analyses of the item intercorrelations and Direct Oblimin rotations of the extracted factors were carried out separately for males and females. The results revealed four factors identified as psychoticism (P), extraversion (E), neuroticism (N) and dissimulation/conformity (L). Internal consistency and test–retest reliability coefficients were satisfactory and very similar to the ones found in the original study. Skewness and kurtosis of the P scale distribution were closer to normal than on the original British revised P scale.     

Insight problem solving in individuals with high versus low schizotypy

Insight problem solving requires restructuring of a problem space by stepping out of the framework provided by the commonly activated cognitive schemas and acquiring a new perspective on the problem. Schizotypy has been linked with loosened associative and overinclusive thinking that may be advantageous for this process. The present study tested this hypothesis and found that individuals with a high degree of schizotypy show better performance on a set of insight problems relative to individuals with low schizotypy, but not on a set of incremental problems that required focused goal-related thinking. Results support the notion that schizotypy is associated not only with enhanced abilities in creative processes involved in divergent thinking but also in creative operations during analytical problem solving.     

The P-psychopathy continuum: Facets of Psychoticism and their associations with psychopathic tendencies

Eysenck proposed that psychopathy is at the extreme end of the Psychoticism (P) personality dimension (Eysenck & Eysenck, 1976). This study examined (i) whether psychopathy-relevant P items of the EPQ-R can form psychometrically valid facets that map onto the conceptualization of the two-, three- or four-factor models of psychopathy using confirmatory factor analysis (N = 577) in a normal population; and (ii) whether those P-facets have criteria-related validity in associations with self-reported primary and secondary psychopathy, impulsivity (subsample N = 306), and measures of trait empathy and aggression (subsample N = 212). The four-factor model incorporating affective, interpersonal, impulsive, and antisocial facets of P was superior to the two-factor model; however, the three-factor conceptualization excluding the antisocial P-facet was the best fit. The facets show predicted divergent associations with primary and secondary self-reported psychopathy and trait measures. Findings are discussed in light of Eysenck’s P-psychopathy continuity hypothesis and the applicability of facet approaches to the prediction of psychopathic and antisocial tendencies.     

Forgiveness and mental health variables: Interpreting the relationship using an adaptational-continuum model of personality and coping

The present paper uses an adaptational-continuum model of personality, based on Ferguson’s (2001) health psychology model integrating Eysenck personality factors and coping style, to provide a context for examining the relationship between forgiveness and mental health. Three hundred and twenty respondents completed measures of personality, coping style, forgiveness (forgiveness of self, others, likelihood, presence of positive forgiveness, absence of negative forgiveness), general health, stress, positive and negative affect and life satisfaction. Among respondents, all measures of forgiveness, bar one, load negatively on a neuroticism-coping factor. The remaining measure of forgiveness (presence of positive forgiveness) loaded on an extraversion-coping factor. The relationship of the neuroticism-coping-forgiveness factor was associated with poorer mental health, suggesting forgiveness is associated with better mental health within the context of this personality-coping factor. Significant positive relationships were found between the extraversion-coping-forgiveness factor and two measures of positive mental health outcomes (positive affect and life satisfaction) suggesting forgiveness is associated with some aspects of mental health within the context of this personality-coping factor. The present findings suggest that forgiveness, or failure to forgive, can be conceptualised within an adaptational-continuum model of personality.     

HiTOP thought disorder,DSM-5 psychoticism,and five factor model openness

HiTOP internalizing, detachment, antagonistic externalizing, and disinhibited externalizing align comfortably with respective domains of the Five-Factor Model (FFM) of general personality. The alignment of HiTOP thought disorder and DSM-5 Section III psychoticism with FFM openness though has been disputed, with the existing research obtaining weak and/or inconsistent results. The purpose of the current paper is to discuss possible reasons for this problematic alignment. The strength of the relationship is hindered in part because it is an alignment of a largely adaptive domain of personality with an entirely maladaptive domain (whereas this is not the case for the other four HiTOP-FFM alignments). The strength of the relationship is also affected by how both openness and psychoticism have been conceptualized and/or assessed.     

Multidimensional perfectionism and the DSM-5 personality traits

Encouraging further research on the dimensional assessment of personality disorders (PDs), Section III of the DSM-5 introduced a hybrid model for the assessment of six PDs employing self-reports on 25 maladaptive personality traits (“DSM-5 personality traits”). Following suggestions that multidimensional perfectionism is an important characteristic across various personality disorders (Ayearst, Flett, & Hewitt, 2012), the present study investigated how personal (self-oriented) and interpersonal (other-oriented and socially prescribed) forms of perfectionism predicted the DSM-5 personality traits in a sample of 311 university students. Multiple regressions (controlling for the overlap between the different forms of perfectionism) showed that socially prescribed perfectionism positively predicted the traits defining schizotypal, borderline, avoidant, and obsessive-compulsive PD; other-oriented perfectionism positively predicted the traits defining narcissistic PD; and both socially prescribed and other-oriented perfectionism positively predicted the traits defining antisocial PD. In contrast, self-oriented perfectionism positively predicted only one of the four traits defining obsessive-compulsive PD (rigid perfectionism). Showing that multidimensional perfectionism predicted all DSM-5 traits defining the personality disorders of Section III, the findings suggest that future DSM-5 updates may profit from including interpersonal aspects of perfectionism as a diagnostic criterion.
