An Introduction to the Five-Factor Model and Its Applications
The five-factor model of personality is a hierarchical organization of personality traits in terms of five basic dimensions: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Research using both natural language adjectives and theoretically based personality questionnaires supports the comprehensiveness of the model and its applicability across observers and cultures. This article summarizes the history of the model and its supporting evidence; discusses conceptions of the nature of the factors; and outlines an agenda for theorizing about the origins and operation of the factors. We argue that the model should prove useful both for individual assessment and for the elucidation of a number of topics of interest to personality psychologists
Personality traits below facets: The consensual validity, longitudinal stability, heritability, and utility of personality nuances
It has been argued that facets do not represent the bottom of the personality hierarchy-even more specific personality characteristics, nuances, could be useful for describing and understanding individuals and their differences. Combining 2 samples of German twins, we assessed the consensual validity (correlations across different observers), rank-order stability, and heritability of nuances. Personality nuances were operationalized as the 240 items of the Revised NEO Personality Inventory (NEO-PI-R). Their attributes were examined by analyzing item residuals, controlling for the variance of the facet the item had been assigned to and all other facets. Most nuances demonstrated significant (p < .0002) cross-method agreement and rank-order stability. A substantial proportion of them (48% in self-reports, 20% in informant ratings, and 50% in combined ratings) demonstrated a significant (p < .0002) component of additive genetic variance, whereas evidence for environmental influences shared by twins was modest. Applying a procedure to estimate stability and heritability of true scores of item residuals yielded estimates comparable with those of higher-order personality traits, with median estimates of rank-order stability and heritability being .77 and .52, respectively. Few nuances demonstrated robust associations with age and gender, but many showed incremental, conceptually meaningful, and replicable (across methods and/or samples) predictive validity for a range of interest domains and body mass index. We argue that these narrow personality characteristics constitute a valid level of the personality hierarchy. They may be especially useful for providing a deep and contextualized description of the individual, but also for the prediction of specific outcomes
Conceptual and methodological issues in the study of the personality-and-culture relationship
Culture-and-personality studies were central to social science in the early 20th century and have recently been revived (as personality-and-culture studies) by trait and cross-cultural psychologists. In this article we comment on conceptual issues, including the nature of traits and the nature of the personality-and-culture relationship, and we describe methodological challenges in understanding associations between features of culture and aspects of personality. We give an overview of research hypothesizing the shaping of personality traits by culture, reviewing studies of indigenous traits, acculturation and sojourner effects, birth cohorts, social role changes, and ideological interventions. We also consider the possibility that aggregate traits affect culture, through psychological means and gene flow. In all these cases we highlight alternative explanations and the need for designs and analyses that strengthen the interpretation of observations. We offer a set of testable hypotheses based on the premises that personality is adequately described by Five-Factor Theory, and that observed differences in aggregate personality traits across cultures are veridical. It is clear that culture has dramatic effects on the thoughts, feelings, and behaviors from which we infer traits, but it is not yet clear whether, how, and in what degree culture shapes traits themselves
Most people’s life satisfaction matches their personality traits:True correlations in multi-trait, multi-rater, multi-sample data
Despite numerous meta-analyses, the true extent to which life satisfaction reflects personality traits has remained unclear due to overreliance on a single method to assess both and insufficient attention to construct overlaps. Using data from three samples tested in different languages (Estonian, N = 20,886; Russian, N = 768; English, N = 600), we combined self- and informant-reports to estimate personality domains’ and nuances’ true correlations (rtrue) with general life satisfaction (LS) and satisfactions with eight life domains (DSs), while controlling for single-method and occasion-specific biases and random error, and avoiding direct construct overlaps. The associations replicated well across samples. The Big Five domains and nuances allowed predicting LS with accuracies up to rtrue ≈.80–.90 in independent (sub)samples. Emotional stability, extraversion, and conscientiousness correlated rtrue≈.30–.50 with LS, while its correlations with openness and agreeableness were small. At the nuances level, low LS was most strongly associated with feeling misunderstood, unexcited, indecisive, envious, bored, used, unable, and unrewarded (rtrue ≈.40–.70). Supporting LS’s construct validity, DSs had similar personality correlates among themselves and with LS, and an aggregated DS correlated rtrue ≈.90 with LS. LS’s approximately 10-year stability was rtrue =.70 and its longitudinal associations with personality traits mirrored cross-sectional ones. We conclude that without common measurement limitations, most people’s life satisfaction is highly consistent with their personality traits, even across many years. So, satisfaction is usually shaped by these same relatively stable factors that shape personality traits more broadly
Mean Profiles of the NEO Personality Inventory
The Revised NEO Personality Inventory (NEO-PI-R, Costa & McCrae, 1992) and its latest version, the NEO-PI-3, were designed to measure 30 distinctive personality traits, which are grouped into Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness domains. The mean self-rated NEO-PI-R scores for 30 subscales have been reported for 36 countries or cultures (McCrae, 2002, Appendix 1). As a follow-up, this study reports the mean scores of the NEO-PI-R/3 for 71,334 participants from 76 samples and 62 different countries or cultures and 37 different languages. Mean differences in personality traits across countries and cultures were about 8 times smaller than differences between any two individuals randomly selected from any of these samples. Nevertheless, systematic differences can be observed in the aggregate personality profiles, in which Anglophonic and Nordic countries are distinguished from the rest of the world. This study provides further evidence that country/culture mean scores in personality are replicable and can provide reliable information about personality dispositions
Developing a Personality Model for Speech-based Conversational Agents Using the Psycholexical Approach
We present the first systematic analysis of personality dimensions developed
specifically to describe the personality of speech-based conversational agents.
Following the psycholexical approach from psychology, we first report on a new
multi-method approach to collect potentially descriptive adjectives from 1) a
free description task in an online survey (228 unique descriptors), 2) an
interaction task in the lab (176 unique descriptors), and 3) a text analysis of
30,000 online reviews of conversational agents (Alexa, Google Assistant,
Cortana) (383 unique descriptors). We aggregate the results into a set of 349
adjectives, which are then rated by 744 people in an online survey. A factor
analysis reveals that the commonly used Big Five model for human personality
does not adequately describe agent personality. As an initial step to
developing a personality model, we propose alternative dimensions and discuss
implications for the design of agent personalities, personality-aware
personalisation, and future research.Comment: 14 pages, 2 figures, 3 tables, CHI'2
