Self-esteemSelf-esteem is confidence in one's own worth, abilities or morals. Self-esteem encompasses beliefs about oneself (for example, "I am loved", "I am worthy") as well as emotional states, such as triumph, despair, pride, and shame. Smith and Mackie (2007) defined it by saying "The self-concept is what we think about the self; self-esteem, is the positive or negative evaluations of the self, as in how we feel about it (see Self).
PsychoticismPsychoticism is one of the three traits used by the psychologist Hans Eysenck in his P–E–N model (psychoticism, extraversion and neuroticism) model of personality. Psychoticism is conceptually similar to the constraint factor in Tellegen's three-factor model of personality. Psychoticism may be divided into narrower traits such as impulsivity and sensation-seeking. These may in turn be further subdivided into even more specific traits. For example, impulsivity may be divided into narrow impulsivity (unthinking responsivity), risk taking, non-planning, and liveliness.
PsychologyPsychology is the study of mind and behavior in humans and non-humans. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.
Facet (psychology)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 (NEO PI-R).
Alternative five model of personalityThe 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.
PsychopathyPsychopathy is a mental health condition characterized by persistent antisocial behavior, impaired empathy and remorse, and bold, disinhibited, and egotistical traits. Different conceptions of psychopathy have been used throughout history that are only partly overlapping and may sometimes be contradictory. Hervey M. Cleckley, an American psychiatrist, influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the Diagnostic and Statistical Manual of Mental Disorders (DSM), as did American psychologist George E.
Obsessive–compulsive personality disorderObsessive–compulsive personality disorder (OCPD) is a cluster C personality disorder marked by a spectrum of obsessions with rules, lists, schedules, and order, among other things. Symptoms are usually present by the time a person reaches adulthood, and are visible in a variety of situations. The cause of OCPD is thought to involve a combination of genetic and environmental factors, namely problems with attachment. Obsessive–compulsive personality disorder is distinct from obsessive–compulsive disorder (OCD), and the relation between the two is contentious.
Harm avoidanceHarm avoidance (HA) is a personality trait characterized by excessive worrying; pessimism; shyness; and being fearful, doubtful, and easily fatigued. In MRI studies HA was correlated with reduced grey matter volume in the orbito-frontal, occipital and parietal regions. Harm avoidance is a temperament assessed in the Temperament and Character Inventory (TCI), its revised version (TCI-R) and the Tridimensional Personality Questionnaire (TPQ) and is positively related to the trait neuroticism and inversely to extraversion in the Revised NEO Personality Inventory and the Eysenck Personality Questionnaire.
ShynessShyness (also called diffidence) is the feeling of apprehension, lack of comfort, or awkwardness especially when a person is around other people. This commonly occurs in new situations or with unfamiliar people; a shy person may simply opt to avoid these situations. Although shyness can be a characteristic of people who have low self-esteem, the primary defining characteristic of shyness is a fear of what other people will think of a person's behavior.
Lexical hypothesisThe lexical hypothesis (also known as the fundamental lexical hypothesis, lexical approach, or sedimentation hypothesis) is a thesis, current primarily in early personality psychology, and subsumed subsequently by many later efforts concerning that topic. Despite some variation of its definition and application, the hypothesis is generally defined by two postulates. The first states that those personality characteristics that are important to a group of people will eventually become a part of that group's language.
