The good judge of personality: Characteristics, behaviors, and observer accuracy

Personality characteristics and behaviors related to judgmental accuracy following unstructured interactions among previously unacquainted triads were examined. Judgmental accuracy was related to social skill, agreeableness, and adjustment. Accuracy of observers of the interactions was positively related to the number of good judges in the interaction, which implies that the personality and behaviors of the judge are important for creating a situation in which targets will reveal relevant personality cues. Furthermore, the finding that observer accuracy was positively related to the number of good judge partners suggests that judgmental accuracy is based on more than detection and utilization skills of the judge.     

Let me read your mind: Personality judgments based on a person’s natural stream of thought

Past research on the accuracy of personality judgments has largely focused on person perception scenarios that are public in nature (e.g., face-to-face interactions, personal websites). This study investigated the accuracy of personality judgments on the basis of highly private information: a person’s natural stream of thought. Nine naïve judges rated the personality of 90 targets on the basis of their 20-min stream-of-consciousness essays. Judges’ level of accuracy was significant and substantial for all Big Five dimensions. The substantial and relatively uniform accuracy across all Big Five dimensions suggests that a person’s moment-to-moment thoughts provide good information for the accurate judgment of personality in general rather than specific diagnostic information for the accurate judgment of private traits such as Neuroticism.     

Personality in middle childhood: A hierarchical structure and longitudinal connections with personality in late adolescence

Research on the structure of personality in middle childhood, while advancing, is still in the early stages of development. In this study, we employed a group of 1563 twins to elucidate the hierarchical structure of personality in middle childhood and provide connections to established personality traits in adult populations. Our results provide evidence for a higher-order structure of personality in middle childhood that maps on to recent findings in adult populations supporting hierarchical relationships among 2-, 3-, 4-, and 5-factor models of personality. In addition, primary higher-order personality traits rated by parents at age 11 showed substantial predictive validity for analogous traits rated by self at age 17. We discuss our results within the context of developing a convergent hierarchical taxonomy of personality in middle childhood and the importance of multi-informant investigations.     

Self and partner personality and responses to relationship threats

Two studies examined the relations between three different types of jealousy and personality characteristics of self and partner in two large heterogeneous community samples of heterosexual couples (459 and 230 couples, respectively). It was expected that partners would resemble each other to some extent in both the experience of different types of jealousy and personality characteristics, and that self-reported levels of neuroticism (+) and extraversion (−) would be related to higher levels of jealousy. Moreover, it was expected that partner extraversion would be related positively to levels of jealousy, and that similarity with regard to personality characteristics would be related to lower levels of jealousy. Results largely supported our expectations with regard to both partner similarity and self-reported personality characteristics. However, our expectations with regard to partner extraversion and similarity were not supported.     

Accuracy of judging others’ traits and states: Comparing mean levels across tests

Tests of accuracy in interpersonal perception take many forms. Often, such tests use designs and scoring methods that produce overall accuracy levels that cannot be directly compared across tests. Therefore, progress in understanding accuracy levels has been hampered. The present article employed several techniques for achieving score equivalency. Mean accuracy was converted to a common metric, pi [Rosenthal, R., & Rubin, D. B. (1989). Effect size estimation for one-sample multiple-choice-type data: Design, analysis, and meta-analysis. Psychological Bulletin, 106, 332–337] in a database of 109 published results representing tests that varied in terms of scoring method (proportion accuracy versus correlation), content (e.g., personality versus affect), number of response options, item preselection, cue channel (e.g., face versus voice), stimulus duration, and dynamism. Overall, accuracy was midway between guessing level and a perfect score, with accuracy being higher for tests based on preselected than unselected stimuli. When item preselection was held constant, accuracy was equivalent for judging affect and judging personality. However, comparisons must be made with caution due to methodological variations between studies and gaps in the literature.     

Trait mechanisms in youth with and without attention-deficit/hyperactivity disorder

Relations of temperament and personality traits within children and adolescents with ADHD and non-ADHD controls were examined. A two-process structure was hypothesized involving top-down effortful and bottom-up reactive response tendencies. Top-down processes were hypothesized to relate to inattentive ADHD symptoms, whereas bottom-up processes were hypothesized to relate to hyperactive–impulsive ADHD symptoms. Each hypothesis was tested in a sample of 179 children age 7–13 (113 boys; 107 ADHD) and then replicated in 184 adolescents age 14–17 (109 boys; 87 ADHD). All families completed a multistage diagnostic process. Youth completed laboratory measures of cognitive control, and parents completed trait ratings. Traits examined in the current study included effortful control, reactive control, resiliency, negative emotionality, neuroticism, extraversion, openness, agreeableness, and conscientiousness. Correlational relations among traits were inconclusive, but external correlations with cognitive tasks and ADHD symptoms were interpretable within the hypothesized two-process framework. Results provide partial support for a distinction between effortful and reactive traits and suggest this distinction is useful in relation to understanding ADHD.     

Explaining intra-individual variability in social behavior through idiographic assessment: The case of humor

Much variability in social behavior is intra-individual; people vary their actions strategically across contexts. Yet most personality assessment methods are inter-individual; they chart between-person differences in average behavioral tendencies. The present research advanced novel idiographic assessment methods to predict intra-individual variability in a behavioral domain of long-standing interest to personality psychologists: humor. Individuals participated in three assessment sessions. Personal beliefs about reasons for using humor were assessed either idiographically or with respect to a nomothetic system of humor-related reasons for action. The subjective relevance of nomothetically- and idiographically-identified reasons to everyday social situations was assessed. Subsequently, participants reported their perceived likelihood of using humor in specific social contexts. As predicted, likelihood of humor use varied substantially as a function of the relevance of situations to idiographically-identified reasons, but did not vary as a function of the relevance of situations to reasons identified nomothetically. Implications for personality and assessment are discussed.     

Who do you think I think I am? Accuracy in perceptions of others’ self-esteem

This study was conducted to assess the accuracy of perceptions of others’ self-esteem and to examine the potential moderating variables of target gender, perceiver gender, and degree of acquaintance. Degree of acquaintance was the only hypothesized moderator reliably related to accuracy. An overall tendency to overestimate targets’ self-esteem was evinced, but was not related to any of the hypothesized moderators. The data suggested that perceivers are influenced by a false consensus effect when estimating others’ level of self-esteem, independent of their degree of acquaintance with targets. Implications of the findings and directions for future investigation are discussed.
