人格心理学的学科架构初探

人格心理学作为心理学体系中的重要分支之一,自创立以来却一直缺乏一个完整统一的学科架构。这种状况极大地限制了该学科的发展。文章回顾了人格心理学的起源和发展,探讨了学科发展的趋势,呈现了当下几种主要的学科架构。在综合比较的基础上,对其中有代表性的Clonlinger人格“描述—动力—发展”的“3D”模型进行了修正：（1）增加了人格理论;（2）把第一个“D”由“人格描述”改为“人格表现”;（3）对原有“3D”的内容进行补充和完善。得出了对人格心理学学科架构的“3D”修正模型：即理论加“3D”     

A study of the dynamics of sex differences in adulthood

Studies of gender differences using primarily young individuals show that males, on average, perform better than females in physical activities but worse than females on tests of verbal abilities. There is however a controversy about the existence of these sex differences in adulthood. Our study used 1271 participants from four cultural backgrounds (Chinese, multi‐generation Canadians, Indu‐Canadians, and European‐Canadians) divided in five age groups. We measured sex differences in the time required for participants to complete a lexical task experiment, and also assessed their verbal tempo and physical endurance using a validated temperament test (Structure of Temperament Questionnaire). We found a significant female advantage in time on the lexical task and on the temperament scale of social–verbal tempo, and a male advantage on the temperament scale of physical endurance. These sex differences, however, were more pronounced in young age groups (17–24), fading in older groups. This “middle age–middle sex” phenomenon suggests that sex differences in these two types of abilities observed in younger groups might be “a matter of age,” and should not be attributed to gender in general. A one‐dimensional approach to sex differences (common in meta‐analytic studies) therefore overlooks a possible interaction of sex differences with age.     

The effect of explicitly varying the proportion of “same” and “different” responses on sex differences in the Shepard and Metzler mental rotation task

The mental rotation of three-dimensional objects is consistently identified as the most salient cognitive sex difference in humans. The Shepard and Metzler task (1971) requires participants to rotate an object in their “mind's eye” and then compare the shape to a second object to identify if the two objects can be aligned in an identical orientation (warranting a “same” response) or represent mirror image shapes of one another (warranting a “different” response). The mental rotation task not only involves a rotational component but also nonrotational components such as comparison and decision making. Recent research has suggested that the sex difference in mental rotation resides in the nonrotational aspects of “different” decisions specifically. This experiment examined this proposal by varying the proportion of “different” decisions across conditions. Participants were ether exposed to the traditional format (50:50 same/different) or a bias towards (75:25) or away from (25:75) different responses. Contrary to previous research, the sex difference was found to reside in “same” responses that required a greater degree of rotation when assessing error rates in mental rotation. Sex differences in mental rotation error rates were particularly sensitive to the rotational aspect of same responses, not rotational aspects of different responses nor nonrotational aspects of both same and different responses. For reaction time, however, a sex difference emerged in the nonrotational aspects of the task. The bias described here affected these nonrotational aspects of the task, but not the rotational aspects, in line with prediction. A second study reran the experiment without making the bias explicit. Under this implicit bias, no sex differences were identified between conditions.     

The Secret Lives of Liberals and Conservatives: Personality Profiles,Interaction Styles,and the Things They Leave Behind

Although skeptics continue to doubt that most people are “ideological,” evidence suggests that meaningful left‐right differences do exist and that they may be rooted in basic personality dispositions, that is, relatively stable individual differences in psychological needs, motives, and orientations toward the world. Seventy‐five years of theory and research on personality and political orientation has produced a long list of dispositions, traits, and behaviors. Applying a theory of ideology as motivated social cognition and a “Big Five” framework, we find that two traits, Openness to New Experiences and Conscientiousness, parsimoniously capture many of the ways in which individual differences underlying political orientation have been conceptualized. In three studies we investigate the relationship between personality and political orientation using multiple domains and measurement techniques, including: self‐reported personality assessment; nonverbal behavior in the context of social interaction; and personal possessions and the characteristics of living and working spaces. We obtained consistent and converging evidence that personality differences between liberals and conservatives are robust, replicable, and behaviorally significant, especially with respect to social (vs. economic) dimensions of ideology. In general, liberals are more open‐minded, creative, curious, and novelty seeking, whereas conservatives are more orderly, conventional, and better organized.     

Measurement invariance of personality traits from a five-factor model perspective: multi-group confirmatory factor analyses of the HP5 inventory

Associations between personality and health may be influenced by contextual factors varying across studied cohorts. Moreover, measurement bias related to contextual factors could also influence these associations. Gender and age have been discussed as important contextual factors when studying personality and health outcomes. An examination of measurement invariance across gender and age may therefore be warranted. In the present study, measurement invariance across age and gender was examined for a five-factor model of personality traits in which scales have been included to operationalise lower-order traits related to health-behaviour or health outcomes. Using multi-group confirmatory factor analysis on a population based cohort (n= 5700), all important parameters of the measurement model were found to be invariant. On the basis of this invariant model, hypotheses of mean differences across age and gender in personality traits were tested. These results were discussed in relation to meta-analyses on personality change and gender differences in personality.     

Why are moderators of self-other agreement difficult to establish?

Agreement between the self and other rated personality profiles was studied in two samples involving 11,096 speakers of two languages, Dutch and Estonian, who completed two different personality questionnaires, the NEO-PI-3 and HEXACO-PI-R. An outstanding agreement was achieved in the most occasions: in only 4–6% of dyadic pairs was the correlation between two randomly paired profiles higher than the actually observed correlation between true pairs. As in previous studies, we found that age and sex of participants and length of acquaintance had no significant effect on the level of self-other agreement. However, intimate knowledge helped married and unmarried couples in both samples be more accurate in their personality judgments; family members, in turn, had knowledge that made them more accurate than two people who were just acquaintances or friends. We believe that these outcomes can be explained by the contention that the judgment of another’s personality is a relatively simple task, which is accomplishable for most people most of the time. In other words, because judging another person’s personality is an easy task, we are not able to determine “good targets,” “good judges,” or “good traits.” Perhaps it is only “good information” which determines the closeness of the target-judge relationship, and which has a small but reliable impact on the level of self-other agreement. This explains why it is so difficult to find individual differences in the ability to judge another person’s personality.     

Predicting the Personal Appeal of Marketing Images Using Computational Methods

Images play a central role in digital marketing. They attract attention, trigger emotions, and shape consumers’ first impressions of products and brands. We propose that the shift from one‐to‐many mass communication to highly personalized one‐to‐one communication requires an understanding of image appeal at a personal level. Instead of asking “How appealing is this image?” we ask “How appealing is this image to this particular consumer?” Using the well‐established five‐factor model of personality, we apply machine learning algorithms to predict an image's personality appeal—the personality of consumers to which the image appeals most—from a set of 89 automatically extracted image features (Study 1). We subsequently apply the same algorithm on new images to predict consequential outcomes from the fit between consumer and image personality. We show that image‐person fit adds incremental predictive power over the images’ general appeal when predicting (a) consumers’ liking of new images (Study 2) and (b) consumers’ attitudes and purchase intentions (Study 3).     

Sex differences in personality are larger in gender equal countries: Replicating and extending a surprising finding

Sex differences in personality have been shown to be larger in more gender equal countries. We advance this research by using an extensive personality measure, the IPIP‐NEO‐120, with large country samples (N > 1000), from 22 countries. Furthermore, to capture the multidimensionality of personality we measure sex differences with a multivariate effect size (Mahalanobis distance D). Results indicate that past research, using univariate measures of effect size, have underestimated the size of between‐country sex differences in personality. Confirming past research, there was a strong correlation (r = .69) between a country's sex differences in personality and their Gender Equality Index. Additional analyses showed that women typically score higher than men on all five trait factors (Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness), and that these relative differences are larger in more gender equal countries. We speculate that as gender equality increases both men and women gravitate towards their traditional gender roles.     

Using a general model of personality to understand sex differences in the personality disorders

In the present study, a general model of personality was used to evaluate sex bias in the personality disorders (PD). This present study compared observed sex differences among the personality disorders (PD) with differences expected based on the Five Factor Model of personality functioning (FFM). Observed sex differences were obtained by metaanalyzing over 30 reports. Expected sex differences were computed using what is known about sex differences in the FFM traits and how these traits relate to the PDs. Agreement between observed and expected sex differences was quite good for eight of ten PDs. For histrionic PD, the obtained sex difference was larger than expected; for schizotypal personality disorder, an expected sex difference was not obtained. Implications of understanding sex differences in terms of the FFM are discussed and suggestions for future research are provided.     

The Openness-calibration hypothesis

The current study tested the hypotheses that (1) psychological adaptations calibrate Openness to Experience to facilitate or deter pursuit of short-term mating, and (2) this calibration varies as a function of mating strategy, physical attractiveness, and sex—individual differences that shift the costs and benefits of alternative personality strategies. Participants completed a personality inventory before and after reading vignettes describing mating opportunities of different durations (short- and long-term) with individuals of differing levels of attractiveness. Among study findings, participants presented with short-term mating opportunities with individuals of average attractiveness exhibited down-regulated Openness relative to those presented with highly attractive mates. Moreover, these effects varied as a function of the interaction between participants’ sex, mating strategy, and attractiveness. These findings are consistent with the hypothesis that evolved psychological mechanisms adaptively calibrate Openness levels in response to short-term mating opportunities. More broadly, they highlight the heuristic value of an evolutionary framework for the study of personality and individual differences.     

Sex stereotypes and implicit personality theory. I. A personality description approach to the assessment of sex stereotypes

It was proposed that sex stereotypes be phrased in terms of the person perception construct, “implicit personality theory,” as the structured sets of inferential relations that link personal attributes to the social categories female and male. The utility of this formulation was assessed by having 31 college students use a set of 66 personality traits to describe other people. A measure of trait co-occurrence was derived from these data and was used as input to Kruskal's multidimensional scaling program. A two-dimensional configuration was interpreted in terms of two orthogonal properties, Social Desirability and Potency. An Indirect Female-Male property (based on the proportion of times each trait was used to describe a male) was strongly related to the configuration and was closely aligned with the Potency vector. Thus, stereotypes of females and males were associated with the Potency dimension of person perception, with females seen as “soft” and males as “hard.” The directly rated sex property Male-Female was also located near the Potency vector, but was not strongly related to the configuration. This lack of fit may have been due to social desirability responding. The results support the utility of formulating sex stereotypes in terms of implicit personality theory and suggest the need to distinguish direct and indirect assessments of stereotypes.     

The General Factor of Personality: A critical test

The present study provides evidence supporting the presence of a General Factor of Personality (GFP), which has been proposed to represent the apex of the hierarchy of personality traits. Furthermore, the construct validity of this general factor is assessed to address recent criticisms suggesting that the GFP may merely be a statistical artefact rather than a genuine higher-order personality dimension. In this study, two samples of monozygotic (MZ) and same-sex dizygotic (DZ) twins completed the NEO Personality Inventory-Revised (NEO-PI-IR), assessing individual differences in the Big Five traits of personality, and the Dimensional Assessment of Personality Problems-Differential Questionnaire (DAPP-DQ) measuring variance in abnormal personality traits. First unrotated factors were extracted from each of the two measures separately within each sample. Correlations between these factors were significant and high in both samples (.78 and .77), indicating that the factors represent similar constructs. The manner in which these findings help to validate the GFP is discussed.     

Personality and gender differences in global perspective

Men's and women's personalities appear to differ in several respects. Social role theories of development assume gender differences result primarily from perceived gender roles, gender socialization and sociostructural power differentials. As a consequence, social role theorists expect gender differences in personality to be smaller in cultures with more gender egalitarianism. Several large cross‐cultural studies have generated sufficient data for evaluating these global personality predictions. Empirically, evidence suggests gender differences in most aspects of personality—Big Five traits, Dark Triad traits, self‐esteem, subjective well‐being, depression and values—are conspicuously larger in cultures with more egalitarian gender roles, gender socialization and sociopolitical gender equity. Similar patterns are evident when examining objectively measured attributes such as tested cognitive abilities and physical traits such as height and blood pressure. Social role theory appears inadequate for explaining some of the observed cultural variations in men's and women's personalities. Evolutionary theories regarding ecologically‐evoked gender differences are described that may prove more useful in explaining global variation in human personality.     

Differential item functioning by sex and race in the Hogan Personality Inventory

The authors examined measurement bias in the Hogan Personality Inventory by investigating differential item functioning (DIF) across sex and two racial groups (Caucasian and Black). The sample consisted of 1,579 Caucasians (1,023 men, 556 women) and 523 Blacks (321 men, 202 women) who were applying for entry-level, unskilled jobs in factories. Although the group mean differences were trivial, more than a third of the items showed DIF by sex (38.4%) and by race (37.3%). A content analysis of potentially biased items indicated that the themes of items displaying DIF were slightly more cohesive for sex than for race. The authors discuss possible explanations for differing clustering tendencies of items displaying DIF and some practical and theoretical implications of DIF in the development and interpretation of personality inventories.     

Considering sex differences in anxiety and its disorders across the life span: A construct-validation approach

One neglected avenue to understanding anxiety disorders is through studying patterns of sex differences, which may suggest the need for modification in definitions of anxiety and its disorders, their operationalization and measurement, and the theories associated with these constructs. This article begins with a comprehensive review of sex diffrences across the life span that supports the widely held view that most anxiety disorders are more common among females than males. Subsequently, we offer an analysis of the possible sources of sex differences from a construct-validity perspective, with emphasis on understanding whether sex differences have their basis in methodological problems, measurement or definitional problems, or problems in extant theories of anxiety themselves.     

人格差异性的进化心理学解释

进化心理学一直热衷于人格共同性的探讨,但一些研究者也认为应该关注人格差异性,因为共同性和差异性是人格必不可分的两面。对人格差异性的进化解释比较成熟的有三种：生活历史理论、基因多样性理论和代价信号理论。生活历史理论认为是不同的环境(稳定和不稳定),造成了不同的生活历史策略(K策略和R策略),人格特质差异是这些策略的进化产物。基因多样性理论主要从基因突变和平衡选择的角度来解释人格差异性。前者强调突变基因的不可避免性引发了个性差异的存在和发展;后者强调概率的调节作用,解释了不同人格特质之所以能够并行存在的原因。代价信号理论则认为是个体拥有的先天禀赋或者资源差距导致其传递信号的能力差异,从而选择了不同的行为策略。未来研究需要加大遗传学、神经科学等方面的力度,以及研究范式的创新。     

The Psychometric Costs of Applicants' Faking: Examining Measurement Invariance and Retest Correlations Across Response Conditions

This study examines the stability of the response process and the rank-order of respondents responding to 3 personality scales in 4 different response conditions. Applicants to the University College of Teacher Education Styria (N = 243) completed personality scales as part of their college admission process. Half a year later, they retook the same personality scales in 1 of 3 randomly assigned experimental response conditions: honest, faking-good, or reproduce. Longitudinal means and covariance structure analyses showed that applicants' response processes could be partially reproduced after half a year, and respondents seemed to rely on an honest response behavior as a frame of reference. Additionally, applicants' faking behavior and instructed faking (faking-good) caused differences in the latent retest correlations and consistently affected measurement properties. The varying latent retest correlations indicated that faking can distort respondents' rank-order and thus the fairness of subsequent selection decisions, depending on the kind of faking behavior. Instructed faking (faking-good) even affected weak measurement invariance, whereas applicants' faking behavior did not. Consequently, correlations with personality scales—which can be utilized for predictive validity—may be readily interpreted for applicants. Faking behavior also introduced a uniform bias, implying that the classically observed mean raw score differences may not be readily interpreted.     

The Effects of Intimacy and Target Sex on Direct Aggression: Further Evidence

The effects on aggression of target sex and relationship with the target were investigated using self‐report data. One hundred and seventy‐four participants (115 female) reported on acts of direct aggression in the last 2 years toward intimate partners, known and unknown same‐sex targets, and known and unknown opposite‐sex targets. Women's self‐reported aggression was higher toward partners than other targets, replicating previous findings regarding women's intimate partner aggression. Women's aggression was consistently higher toward same‐sex than opposite‐sex targets, but the effect of knowing the target was inconsistent. Men's self‐reported aggression was more frequent toward same‐sex than opposite‐sex targets—including intimate partners—and more frequent toward known than unknown targets. Results are discussed with reference to a partner‐specific reduction in women's fear, and sex differences in threshold for classifying someone as “known well.” Limitations of the present sample and suggestions for future work are discussed.

The “Perseverant” Personality: A Preattachment Perspective on the Etiology and Evolution of Binge/Purge Eating Disorders

The author integrates “psycho-digestive” metaphor with contemporary relational perspectives and developmental research to propose a way of thinking about the etiology and evolution of binge/purge eating disorders—including “purging anorexia,” bulimia, and “yo-yo” binge/dieting—and the personality organization that may underlie them. Focusing on the unifying, cyclical nature of these disorders, the author hypothesizes that an early-developing, fear-based form of somatopsychic perseveration may be set in motion from the beginning of life when a nursing infant is unable to achieve a psychic connection with a physically present and feeding (m)other. Without intervention, such a preattachment failure in (m)other/infant synchrony would inevitably impact all subsequent development. The author proposes that it may also lay the foundation for a uniquely intertwined somatopsychic personality organization—what she calls a “perseverant” personality—that fosters the development of binge/purge eating disorders. A perseverant personality is defined as a solitary and circular mode of being, thinking, and relating that is organized around a sustained physiological and psychological reliance on the feeding as a mode of thought-processing and affect regulation.
