DeYoung earned his A.B. in the Mind, Brain, Behavior program of the History and Science concentration at Harvard University in 1998. He obtained his M.A. and Ph.D. in psychology in 2000 and 2005, respectively, at the University of Toronto [1] where he studied under Jordan B. Peterson.
DeYoung's research in personality psychology has examined the theoretical structure of personality and the biological basis of personality.
In contemporary psychology, the most commonly accepted model of personality structure is the "Big Five" or "Five Factor Model." [3] [4] Recent research using factor analysis has suggested that the five domains of the Big Five have two higher-order factors, referred to as metatraits. [5] [6] The two metatraits are Stability, which is composed of Big Five factors of Agreeableness, Conscientiousness, and Emotional Stability (the reverse of Neuroticism) and Plasticity, which includes the Big Five factors of Extraversion and Openness/Intellect (commonly referred to as Openness to Experience). Stability is defined by one's maintenance of stability and hypothesized to be related to the neurotransmitter serotonin, while Plasticity is seen in one's adaptability to novelty and hypothesized to be related to the neurotransmitter dopamine. [6] [7] DeYoung has also proposed an expanded classification of the Big Five dividing each of the Big Five into two sub-dimensions. DeYoung, Quilty and Peterson (2007) [8] suggested the following aspects of the Big Five factors:
The classification system utilizing these ten aspects allows for nuanced discrimination within the Big Five, which can reveal subtleties in differences in personality domains otherwise undetected.
DeYoung et al.'s (2010) [9] research indicates that the sizes of certain brain regions are related to four of the five different domains of the Five Factor Model. The volume of the medial orbitofrontal cortex, which is responsible for coding reward values, was positively associated with Extraversion. Neuroticism was related to reduced dorsomedial prefrontal cortex and posterior hippocampus volume and increased mid-cingulate gyrus volume, which are areas sensitive to threat and punishment and associated with negative emotion and emotional dysregulation. Reduced posterior left superior temporal sulcus and increased posterior cingulate cortex and fusiform gyrus volume were associated with Agreeableness and have been shown to be involved in interpretation of others' motives and beliefs. Increased volume in the middle frontal gyrus in the left lateral prefrontal cortex, an area responsible for maintaining and executing information and planned action, was positively correlated with Conscientiousness. Openness/Intellect (Openness to Experience) was the only member of the Big Five lacking a significant relationship to brain structure volume. However, other research by DeYoung et al. (2009) [10] has shown that Openness/Intellect is related to brain function in prefrontal cortex.
A helpful overview of 'Personality and the Brain' is provided by Glenn Wilson (2012) [11] while Allen & DeYoung (2016) provide an overview article of 'Personality Neuroscience and the Five-factor model' in the Oxford Handbook of the Five Factor Model of Personality. [12]
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 onward in psychological trait theory.
Facial symmetry is one specific measure of bodily symmetry. Along with traits such as averageness and youthfulness it influences judgments of aesthetic traits of physical attractiveness and beauty. For instance, in mate selection, people have been shown to have a preference for symmetry.
In the study of psychology, neuroticism has been considered a fundamental personality trait. For example, in the Big Five approach to personality trait theory, individuals with high scores for neuroticism are more likely than average to be moody and to experience such feelings as anxiety, worry, fear, anger, frustration, envy, jealousy, guilt, depressed mood, and loneliness. Such people are thought to respond worse to stressors and are more likely to interpret ordinary situations, such as minor frustrations, as appearing hopelessly difficult.
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.
Openness to experience is one of the domains which are used to describe human personality in the Five Factor Model. Openness involves six facets, or dimensions: active imagination (fantasy), aesthetic sensitivity, attentiveness to inner feelings, preference for variety (adventurousness), intellectual curiosity, and challenging authority. A great deal of psychometric research has demonstrated that these facets or qualities are significantly correlated. Thus, openness can be viewed as a global personality trait consisting of a set of specific traits, habits, and tendencies that cluster together.
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 traits of extraversion and introversion are a central dimension in some human personality theories. The terms introversion and extraversion were introduced into psychology by Carl Jung, although both the popular understanding and current psychological usage vary. Extraversion tends to be manifested in outgoing, talkative, energetic behavior, whereas introversion is manifested in more reflective and reserved behavior. Jung defined introversion as an "attitude-type characterised by orientation in life through subjective psychic contents", and extraversion as "an attitude-type characterised by concentration of interest on the external object".
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 assesses an individual on five dimensions of personality, the so-called Big Five personality traits. These traits are openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. In addition, the NEO PI-R also reports on six subcategories of each Big Five personality trait.
Within personality psychology, 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 changes are changes in individuals personalities over time. Originally thought to be concrete and unchanging, recent studies have found evidence that personality can change throughout a person's life.
The Big Five personality traits are Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism. The Big Five Personality is a test that people can take to learn more about their personality in relation to the five personality traits. 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 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. The Big Five model of personality started in the United States, and through the years has been translated into many different languages and has been used in many countries. Some researchers were attempting to determine the differences in how other cultures perceive this model. 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 countries such as South America and East Asia, the results weren't as accurate because they weren't as open as some people in other countries are.
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.
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 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. He earned his Ph.D. in 1976, and worked 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.
