A quantitative evaluation of sex differences in implicit personality theories

An investigation is conducted into whether male and female perceivers hold substantially different implicit theories of personality. 24 male and 24 female subjects were asked to sort a set of 36 trait names into groups of similar traits. On the basis of these data, proximities between trait names and proximities between groupings (or partitions) were computed and subjected to a differential statistical analysis. Neither a global test for sex-specific groupings of trait names nor tests at the level of perceived pairwise trait relationships yielded significant differences. It is concluded that aggregation of sorting data over both male and female perceivers is warranted without too big a loss of information. On the methodological side, this paper demonstrates the feasibility of a quantitative approach to handling the problem of data aggregation in the context of studies using the sorting method as a data-gathering technique.     

Consumers' implicit theories about personality influence their brand personality judgments

Three studies document that consumers' implicit theories about the fixedness/malleability of personality guide brand personality updating in a brand extension context. The first two studies show that extension fit with the parent brand impacts brand personality updating only for incremental (vs. entity theorists). Specifically, for incremental theorists, brand personality is enhanced (vs. diluted) when extension fit is poor (vs. good), and only when brand personality is salient. The third study identifies conditions under which entity theorists focus on brand personality. Interestingly, overall evaluations of the parent brand and extension vary only with extension fit. Implications of our research are discussed.     

自恋型人格的理论模型与神经生理机制

自恋作为一种人格特质, 核心特征是具有夸张和膨胀的自我观点。当前研究将自恋型人格与不同的自我特征相联系, 这些特征包括了夸张性、崇拜的需要、自我中心和高自尊、情感共情缺乏和述情障碍, 研究表明自恋的夸张性和崇拜需要源自扭曲的自我观点和自我提升。当前研究发现额中回、内侧前额叶皮层、眶额叶皮层、揳前叶和前脑岛与自我提升和自我评估有关。前脑岛、右背外侧前额叶皮层和右侧后扣带回皮层与共情缺失有关。未来研究应注重将遗传学、电生理学、生物化学、脑成像等技术的结合, 构建自恋型人格形成的神经生理模型。     

The relationship between maladaptive personality functioning and problematic technology use in adolescence: A cluster analysis approach

In the last two decades, scientific research has explored the problematic use of internet, videogames and mobile phones. However, there is still little consistent knowledge regarding the co-occurrence of problematic technology use and the role of maladaptive personality characteristics in adolescence. The present study aimed to investigate adolescents' styles of technology use with a cluster analysis approach focusing on personality functioning. The sample comprised 408 Italian adolescents (46.3% males) aged 11 to 18 years (M _age = 13.80; SD = 2.08). Data were collected using the Internet Addiction Test, the Videogame Dependency Scale, the Test of Mobile-Phone Dependence Brief Form and the Personality Inventory for DSM5 Brief Form. Results provided a four-cluster solution based on the co-occurrence of problematic technology use. The four clusters were labeled as follows: cluster 1: “Above average internet and mobile-phone use”; cluster 2: “Below average technology use”; cluster 3: “Above average videogame use”; and cluster 4: “Problematic technology use.” Analyses on demographic variables (e.g., gender and age) demonstrated significant differences between the four groups. Adolescents with high levels of problematic technology use reported greater overall personality dysfunction than the other three groups. This finding supported our hypothesis on maladaptive personality functioning in adolescents at risk for addiction. Finally, the Antagonism domain played a specific role in differentiating the severity of adolescents' involvement in technology use. Further studies are needed to confirm our findings and to plan preventive interventions as well as therapeutic treatments.     

A taxometric analysis of psychopathic personality

Although a common assumption throughout much of the professional and popular literature is that psychopaths are qualitatively different from others, very few studies have examined the latent structure of psychopathy. Whether psychopathy is a discrete category or a continuous dimension may have implications for research on the assessment, etiology, and treatment of this disorder. This study examined the latent structure of psychopathy in a sample of 309 jail and prison inmates. Three taxometric procedures were used to analyze indicators drawn from the Psychopathic Personality Inventory (S. O. Lilienfeld & B. P. Andrews, 1996), a self-report instrument. Consistent with prior studies that used other measures of psychopathy, none of the analyses was consistent with a taxonic solution, suggesting that psychopathic personality may be best understood as existing on a continuum.     

The relation between implicit theories of personality and forgiveness

This research examined the effect of implicit theories of personality on interpersonal forgiveness and the mediating mechanism underlying this effect. Two experiments show that incremental personality theorists are less forgiving than entity personality theorists and that this difference can be explained by the incremental theorists’ stronger tendency to appraise the transgressor as responsible for causing the hurtful event. The same findings were obtained regardless of whether forgiveness was measured by self‐report or assessed as responses to anger words in a latency response task.     

The use of psychological theories by ‘naive’ judges: A study in implicit personality theory

Sixty-three subjects judged the behaviour of one of two fictitious stimulus persons by means of five different types of explanation which corresponded with specific psychological theories. These types of explanation based behaviour on adaptation to external conditions, reward/punishment, fulfilment of role expectations, effects of unconscious motives and the imitation of models. The explanations were evaluated on graphic rating scales as to their truth and convincingness. Two-way analyses of variance with repeated measures on one factor showed significant main effects for type of explanation and interaction effects of stimulus person × type of explanation for both dependent variables. The results are discussed in the light of studies done so far in implicit personality theory.
