In psychology, trait theory is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of traits, which can be defined as habitual patterns of behaviour, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals, are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions.
Conscientiousness is the personality trait of being careful, or diligent. Conscientiousness implies a desire to do a task well, and to take obligations to others seriously. Conscientious people tend to be efficient and organized as opposed to easy-going and disorderly. They exhibit a tendency to show self-discipline, act dutifully, and aim for achievement; they display planned rather than spontaneous behavior; and they are generally dependable. It is manifested in characteristic behaviors such as being neat, and systematic; also including such elements as carefulness, thoroughness, and deliberation.
The Big Five personality traits is a suggested taxonomy, or grouping, for personality traits, developed from the 1980s onwards in psychological trait theory. When factor analysis is applied to personality survey data, it reveals semantic associations: some words used to describe aspects of personality are often applied to the same person. For example, someone described as conscientious is more likely to be described as "always prepared" rather than "messy". These associations suggest five broad dimensions used in common language to describe the human personality, temperament and psyche.
Psychoticism is one of the three traits used by the psychologist Hans Eysenck in his P–E–N model model of personality.
Agreeableness is a personality trait manifesting itself in individual behavioral characteristics that are perceived as kind, sympathetic, cooperative, warm, and considerate. In contemporary personality psychology, agreeableness is one of the five major dimensions of personality structure, reflecting individual differences in cooperation and social harmony.
Affective events theory (AET) is a model developed by organizational psychologists Howard M. Weiss and Russell Cropanzano to explain how emotions and moods influence job performance and job satisfaction. The model explains the linkages between employees' internal influences and their reactions to incidents that occur in their work environment that affect their performance, organizational commitment, and job satisfaction. The theory proposes that affective work behaviors are explained by employee mood and emotions, while cognitive-based behaviors are the best predictors of job satisfaction. The theory proposes that positive-inducing as well as negative-inducing emotional incidents at work are distinguishable and have a significant psychological impact upon workers' job satisfaction. This results in lasting internal and external affective reactions exhibited through job performance, job satisfaction, and organizational commitment.
The Temperament and Character Inventory (TCI) is an inventory for personality traits devised by Cloninger et al. It is closely related to and an outgrowth of the Tridimensional Personality Questionnaire (TPQ), and it has also been related to the dimensions of personality in Zuckerman's alternative five and Eysenck's models and those of the five factor model.
The HEXACO model of personality structure is a six-dimensional model of human personality that was created by Ashton and Lee and explained in their book, The H Factor of Personality, based on findings from a series of lexical studies involving several European and Asian languages. The six factors, or dimensions, include Honesty-Humility (H), Emotionality (E), Extraversion (X), Agreeableness (A), Conscientiousness (C), and Openness to Experience (O). Each factor is composed of traits with characteristics indicating high and low levels of the factor. The HEXACO model was developed through similar methods as other trait taxonomies and builds on the work of Costa and McCrae and Goldberg. The model, therefore, shares several common elements with other trait models. However, the HEXACO model is unique mainly due to the addition of the Honesty-Humility dimension.
The Revised NEO Personality Inventory is a personality inventory that examines a person's Big Five personality traits. In addition, the NEO PI-R also reports on six subcategories of each Big Five personality trait.
It has become common practice to use factor analysis to derive personality traits. The Big Five model proposes that there are five basic personality traits. These traits were derived in accordance with the lexical hypothesis. These five personality traits: Extraversion, Neuroticism, Agreeableness, Conscientiousness and Openness to Experience have garnered widespread support.
Personality is the makeup of an individuals thinking, feeling, and behavior and is bound to change over the period of a lifetime. Although there is little research overall, there has been compelling initial evidence for personality change. The development of personality is often dependent on the stage of life a person is in, and the extent to which one's levels of characteristics, relative to their age cohort, is stable across long periods of time. Cultural and environmental influence are large factors in personality trait differences. Personality change is usually seen over longer periods of time and is analogical to height, as most development occurs in the earlier stages of life and becomes more stable as one grows into adulthood. The Big Five, or Five Factor Model, is the most widely accepted form of personality theory, and especially in terms of personality change. Research suggests that genetics play a role in the change and stability of certain traits in a personality. They have also discovered environmental and situational/contextual sources affect personality. Some debates have pervaded the field of psychology since its beginning. One of the most debated deals with the nature and development of personality. Personality psychology studies one's distinctive style of cognition, behavior, and affect. However, this concept elicits discord among psychologists as some have insisted that it does not exist, while others struggle with issues of measurement.
Cross-cultural psychology as a discipline examines the way that human behavior is different and/or similar across different cultures. One important and widely studied area in this subfield of psychology is personality, particularly the study of Big Five. The Big Five personality traits are Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The Big Five model of personality has become the most extensively studied model of personality and has broad support, starting in the United States and later in many different cultures. Some research shows that the Big Five holds up across cultures even with its origin in the English language. However, there is also some evidence which suggests that the Big Five traits may not be sufficient to completely explain personality in other cultures.
In psychology, a facet is a specific and unique aspect of a broader personality trait. Both the concept and the term "facet" were introduced by Paul Costa and Robert McCrae in the first edition of the NEO-Personality Inventory (NEO-PI) Manual. Facets were originally elaborated only for the neuroticism, openness to experience, and extraversion traits; Costa and McCrae introduced facet scales for the agreeableness and conscientiousness traits in the Revised NEO-PI. Each of the Big Five personality traits in the five factor model contains six facets, each of which is measured with a separate scale. The use of facets and facet scales has since expanded beyond the NEO PI-R, with alternative facet and domain structures derived from other models of personality. Examples include the HEXACO model of personality structure, psycholexical studies, circumplex models, the Multidimensional Personality Questionnaire (MPQ), and the California Psychological Inventory.
Colin G. DeYoung is an associate professor of psychology at the University of Minnesota. His research is in the field of personality psychology and personality neuroscience.
Most scientists agree that religiosity is not an independent personality trait, despite there being some commonality between their characteristics. Religiosity and personality traits both relate to one's feelings, thoughts, and behaviors. However, unlike for personality, one's level of religiosity is often measured by the presence or lack of belief in and relationship with a higher power, certain lifestyles or behaviors adopted for a higher power, and a sense of belonging with other followers of one's religion. Additionally, personality traits tend to follow a normal distribution, such that the majority of individuals' scores for a personality trait will be concentrated towards the middle, rather than being extremely high or low. Distributions for religiosity, however, follow a non-normal distribution, such that there are more individuals who score particularly high or low on religiosity scales.
The alternative five model of personality is based on the claim that the structure of human personality traits is best explained by five broad factors called impulsive sensation seeking (ImpSS), neuroticism–anxiety (N-Anx), aggression–hostility (Agg-Host), sociability (Sy), and activity (Act). The model was developed by Marvin Zuckerman and colleagues as a rival to the well-known Five factor model of personality traits and is based on the assumption that "basic" personality traits are those with a strong biological-evolutionary basis. One of the salient differences between these two models is that the alternative five model lacks any equivalent to the dimension called openness to experience in the five factor model.
The biological basis of personality is the collection of brain systems and mechanisms that underlie human personality. Human neurobiology, especially as it relates to complex traits and behaviors, is not well understood, but research into the neuroanatomical and functional underpinnings of personality are an active field of research. Animal models of behavior, molecular biology, and brain imaging techniques have provided some insight into human personality, especially trait theories.
Robert Roger McCrae is a personality psychologist at the National Institute of Aging. He is associated with the Five Factor Theory of personality. He has spent his career studying the stability of personality across age and culture. Along with Paul Costa, he is a co-author of the Revised NEO Personality Inventory. He has served on the editorial boards of many scholarly journals, including the Journal of Personality and Social Psychology, the Journal of Research in Personality, the Journal of Cross-Cultural Psychology, and the Journal of Individual Differences.
Intelligence and personality have traditionally been studied as separate entities in psychology, but more recent work has increasingly challenged this view. An increasing number of studies have recently explored the relationship between intelligence and personality, in particular the Big Five personality traits.
Personality traits are patterns of thoughts, feelings and behaviors that reflect the tendency to respond in certain ways under certain circumstances.
