Information quality in personality judgment: The value of personal disclosure

We examined the relative quality of different types of information and its effects on accuracy in personality judgment. Three hundred and forty-four unacquainted undergraduates participated in a small group round-robin rating scheme. In one condition, participants were asked to disclose three things that were very important to them in life. In a second condition, participants were asked to disclose three distinctive personal facts: things that differentiated them from others. We found that (a) people believed values information was more personality-relevant than facts information and (b) although there was no clear advantage for one condition over the other in terms of generalized accuracy, there were some differences across conditions for specific traits. Implications for the study of information quality in personality judgment are discussed.     

Information quantity and quality affect the realistic accuracy of personality judgment

Triads of unacquainted college students interacted in 1 of 5 experimental conditions that manipulated information quantity (amount of information) and information quality (relevance of information to personality), and they then made judgments of each others' personalities. To determine accuracy, the authors compared the ratings of each judge to a broad-based accuracy criterion composed of personality ratings from 3 types of knowledgeable informants (the self, real-life acquaintances, and clinician-interviewers). Results supported the hypothesis that information quantity and quality would be positively related to objective knowledge about the targets and realistic accuracy. Interjudge consensus and self-other agreement followed a similar pattern. These findings are consistent with expectations based on models of the process of accurate judgment (D. C. Funder, 1995, 1999) and consensus (D. A. Kenny, 1994).     

An Examination of Information Quality as a Moderator of Accurate Personality Judgment

Information quality is an important moderator of the accuracy of personality judgment, and this article describes research focusing on how specific kinds of information are related to accuracy. In this study, 228 participants (159 female, 69 male; mean age = 23.43; 86.4% Caucasian) in unacquainted dyads were assigned to discuss thoughts and feelings, discuss behaviors, or engage in behaviors. Interactions lasted 25–30 min, and participants provided ratings of their partners and themselves following the interaction on the Big Five traits, ego‐control, and ego‐resiliency. Next, the amount of different types of information made available by each participant was objectively coded. The accuracy criterion, composed of self‐ and acquaintance ratings, was used to assess distinctive and normative accuracy using the Social Accuracy Model. Participants in the discussion conditions achieved higher distinctive accuracy than participants who engaged in behaviors, but normative accuracy did not differ across conditions. Information about specific behaviors and general behaviors were among the most consistent predictors of higher distinctive accuracy. Normative accuracy was more likely to decrease than increase when higher‐quality information was available. Verbal information about behaviors is the most useful for learning about how people are unique.     

Different signals of personality and health from the two sides of the face

Previous studies demonstrate that people with different personality traits have different-looking faces. We investigated whether personality and health information are differently signalled by the two hemifaces. Using composite images created from women with high and low scores on health and personality dimensions, we investigated discrimination accuracy with original and mirrored hemifaces. By comparing discrimination accuracy for particular types of hemiface, we address issues regarding both the location of information signals and how these signals are conveyed. From the hemiface stimuli, participants could accurately identify three of the Big Five traits, along with health. We found differences in which hemiface could be more accurately identified, depending on the expressed trait. Emotional stability and health were more accurately discriminated from the right hemiface, while extraversion showed higher accuracy from the left hemiface. We found evidence for differences between hemifaces related to both directional asymmetries and to other information content. Finally, our results also address ongoing debate about which side of the face is more attractive, as we found attractiveness differences between hemifaces depended upon the personality trait most clearly expressed.     

The Effect of Information Quantity on Distinctive Accuracy and Normativity of Personality Trait Judgments

Information quantity is an important moderator of personality judgment accuracy. Some evidence suggests that the amount of available information is positively related to accuracy. The current study utilized the social accuracy model to investigate the effects of differences in thin slices of information quantity on the distinctive accuracy and normativity of personality trait judgments. It was hypothesized that distinctive accuracy and normativity would increase as information quantity increased. Participants were 431 individuals who participated in an online study that varied the length of stimulus target observations (30 seconds, 1 minute, 3 minutes, and 5 minutes), after which judges rated targets using other‐report measures of the Big Five personality traits. For all traits combined, significant levels of accuracy were found for all observation lengths, but distinctive accuracy and normativity did not increase as video length increased. Findings varied for individual traits. For distinctive accuracy, there was a linear increase with information quantity for Extraversion and a non‐linear relationship for Conscientiousness, while there was a linear decrease for Openness. For normativity, there was a linear increase with information quantity for Agreeableness and a non‐linear relationship for Conscientiousness. There are important differences in how observation length affects distinctive accuracy and normativity for different personality traits. © 2019 European Association of Personality Psychology     

Personality and motivation: Sources of inefficiency in cognitive performance

Impulsivity and anxiety are two dimensions of personality which have strong effects upon the efficiency of cognitive performance. The effects of these two variables depend upon characteristics of the task as well as upon four types of tradeoffs between psychological resources. Tasks may be characterized in terms of their relative requirements for sustained information transfer (SIT), short-term memory (STM), and long-term memory (LTM). Resource tradeoffs may be automatic, strategic, directional, or stylistic. Impulsivity effects on performance involve an automatic arousal-induced tradeoff between SIT and STM, strategic tradeoffs of speed for accuracy, and stylistic differences in persistence. Anxiety effects involve strategic, directional, and stylistic tradeoffs.     

Personality and the response to predation risk: effects of information quantity and quality

Within aquatic ecosystems, chemosensory cues provide valuable public information regarding the form and degree of risk, allowing prey to make informed behavioural decisions. Such cues, however, may vary in both relative concentration detected (i.e. ‘quantity’) and reliability of the information available (i.e. ‘quality’), leading to varying response patterns. Moreover, prey species are also known to exhibit consistent behavioural tactics towards managing risk (i.e. personality), possibly shaping their use of public information. Here, we present two experiments examining the potential interacting effects of personality and the quantity (Experiment 1) or quality (Experiment 2) of public information on the short-term predator avoidance responses of wild-caught Trinidadian guppies under semi-natural conditions. Our first experiment demonstrated that personality shaped responses to a high concentration of alarm cues (high risk), with shyer guppies exhibiting stronger antipredator responses than bolder guppies. When exposed to either low risk or stream water controls, personality had no effect on the intensity of response. Our second experiment demonstrated that personality again shaped the response to high concentrations of alarm cues (a known risk) but not to a novel chemosensory cue (tilapia odour). When exposed to the unknown novel cue, guppies exhibited a relatively high intensity antipredator response, regardless of personality. Combined, our results suggest that individual risk-taking tactics shape the use of public information in a context-dependent fashion.     

Replicability and 40-year predictive power of childhood ARC types

We examined 3 questions surrounding the undercontrolled, overcontrolled, and resilient-or Asendorpf-Robins-Caspi (ARC)-personality types originally identified by Block (1971). In analyses of the teacher personality assessments of over 2,000 children in 1st through 6th grade in 1959-1967 and follow-up data on general and cardiovascular health outcomes in over 1,100 adults recontacted 40 years later, we found bootstrapped internal replication clustering suggesting that Big Five scores were best characterized by a tripartite cluster structure corresponding to the ARC types. This cluster structure was fuzzy rather than discrete, indicating that ARC constructs are best represented as gradients of similarity to 3 prototype Big Five profiles; ARC types and degrees of ARC prototypicality showed associations with multiple health outcomes 40 years later. ARC constructs were more parsimonious but, depending on the outcome, comparable or slightly worse classifiers than the dimensional Big Five traits. Forty-year incident cases of heart disease could be correctly identified with 67% accuracy by childhood personality information alone and stroke incidence with over 70% accuracy. Findings support the theoretical validity of ARC constructs, their treatment as continua of prototypicality rather than discrete categories, and the need for further understanding the robust predictive power of childhood personality for midlife health.     

Prototypicality and personality: Effects on free recall and personality impressions

An experiment was performed to test the hypothesis that it is easier to process information about characters who fit well with and are, therefore, “prototypical” of shared beliefs about various personality types. Character prototypicality was manipulated in a free recall and personality impression paradigm through variations in the consistency of a character's identification with preexisting beliefs about two personality-type categories—extraversion and introversion. Subjects also were given information about each character that varied in degree of abstraction from traits to concrete behavior. As predicted, both the amount and nature of the information correctly recalled were significantly affected by the consistency of the character's identification with extraversion or with introversion. Character consistency also significantly affected the amount of material written in the personality impressions and the tendency to qualify the generality of the impressions. The results support a model in which incoming data about personality are coded, structured, elaborated, and remembered according to the quality of their match with preexisting beliefs about various personality types.     

Motivated information processing and group decision-making: Effects of process accountability on information processing and decision quality

Integrating dual-process models [Chaiken, S., & Trope, Y. (Eds.). (1999). Dual-process theories in social psychology. NewYork: Guilford Press] with work on information sharing and group decision-making [Stasser, G., & Titus, W. (1985). Pooling of unshared information in group decision making: biased information sampling during discussion. Journal of Personality and Social Psychology, 48, 1467-1478.], we predicted that groups with high epistemic motivation engage in more information-driven and less preference-driven interaction, and achieve better decisions. An experiment manipulating process accountability showed that groups under process accountability experienced greater need for more information, repeated unshared information more often, and more often chose the correct decision alternative. Mediation analysis established that epistemic motivation produced high quality decisions because it stimulated systematic information processing. Results also revealed that preference heterogeneity stimulated information-driven interaction and led to higher decision quality.     

人格判断的准确性:特质特性的作用

特质特性是影响人格判断准确性的重要调节变量。已有的研究表明,可观察性高的特质容易判断,判断的准确性和一致性也更高;特质的可评估性干扰了自我知觉的准确性,与中性特质相比,可评估性特质的自我—他人一致性更低;与清晰特质相比,模糊特质的自我—同伴判断间的一致性更低,且随特质模糊性的增加而递减。不仅如此,特质特性经常与其他因素如熟悉度交互作用于人格判断的准确性,在考查特质特性的作用时,必须提高研究的生态效度,将该变量与特性匹配、特质分类、个体差异及文化差异等因素综合起来考虑。     

品牌印象研究述评

品牌印象是消费者基于对品牌信息的感知和体验而在头脑中留下的品牌部分或整体信息。品牌印象形成涉及到类别信息加工和个别化信息加工两方面,其认知加工模式还存在争议。品牌印象实证研究主要存在以品牌主观形象为核心的品牌印象研究和以品牌拟人化特征为焦点的品牌印象研究两条线路。在分析比较的基础上,我们认为无论是品牌形象研究线路还是品牌人格研究线路,探讨的都是品牌的客观特性在消费者头脑中留下的主观印象,其本质都是对消费者品牌印象的研究。品牌印象是品牌与消费者的关系基础。品牌建设的任务就是在深刻把握消费者品牌印象形成机制的基础上,通过调节和控制消费者对品牌的认知、联想、态度、信任和忠诚来积累品牌资产。     

Internal facial features are signals of personality and health

We investigated forms of socially relevant information signalled from static images of the face. We created composite images from women scoring high and low values on personality and health dimensions and measured the accuracy of raters in discriminating high from low trait values. We also looked specifically at the information content within the internal facial features, by presenting the composite images with an occluding mask. Four of the Big Five traits were accurately discriminated on the basis of the internal facial features alone (conscientiousness was the exception), as was physical health. The addition of external features in the full-face images led to improved detection for extraversion and physical health and poorer performance on intellect/imagination (or openness). Visual appearance based on internal facial features alone can therefore accurately predict behavioural biases in the form of personality, as well as levels of physical health.     

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.     

An other perspective on personality: meta-analytic integration of observers' accuracy and predictive validity

The bulk of personality research has been built from self-report measures of personality. However, collecting personality ratings from other-raters, such as family, friends, and even strangers, is a dramatically underutilized method that allows better explanation and prediction of personality's role in many domains of psychology. Drawing hypotheses from D. C. Funder's (1995) realistic accuracy model about trait and information moderators of accuracy, we offer 3 meta-analyses to help researchers and applied psychologists understand and interpret both consistencies and unique insights afforded by other-ratings of personality. These meta-analyses integrate findings based on 44,178 target individuals rated across 263 independent samples. Each meta-analysis assessed the accuracy of observer ratings, as indexed by interrater consensus/reliability (Study 1), self-other correlations (Study 2), and predictions of behavior (Study 3). The results show that although increased frequency of interacting with targets does improve accuracy in rating personality, informants' interpersonal intimacy with the target is necessary for substantial increases in other-rating accuracy. Interpersonal intimacy improved accuracy especially for traits low in visibility (e.g., Emotional Stability) but only minimally for traits high in evaluativeness (e.g., Agreeableness). In addition, observer ratings were strong predictors of behaviors. When the criterion was academic achievement or job performance, other-ratings yielded predictive validities substantially greater than and incremental to self-ratings. These findings indicate that extraordinary value can gained by using other-reports to measure personality, and these findings provide guidelines toward enriching personality theory. Various subfields of psychology in which personality variables are systematically assessed and utilized in research and practice can benefit tremendously from use of others' ratings to measure personality variables.     

Accuracy of Social Perception: An Integration and Review of Meta‐Analyses

This review examines the overall accuracy of social perception across several research topics and identifies factors that influence the accuracy of social perception. Findings from 14 meta‐analyses examining topics such as social/personality judgments, health judgments, legal judgments, and academic/vocational judgments were obtained. Social perception accuracy was generally moderate, yielding an average effect size (r) of .32. However, individual meta‐analytic effects varied widely, with some topics yielding small effects (e.g., lie detection, eyewitness identification) and other topics yielding large effects (e.g., educational judgments, health judgments). Several moderators of social perception accuracy were identified, including the nature of the information source, familiarity of the target, type of personality trait, and severity of the outcome being judged. These findings provide a comprehensive summary and novel integration of disparate findings on the accuracy of social perception. Concluding remarks highlight avenues for future research and call for cross‐disciplinary collaborations that would enhance our understanding of social perception.     

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.
