Harm Avoidance
Harm 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. Researchers have contended that harm avoidance represents a composite personality dimension with neurotic introversion at one end of the spectrum and stable extraversion at the other end. Harm avoidance has also been found to have moderate inverse relationships with conscientiousness and openness to experience in the five factor model In personality psychology and psychometrics ...

Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, treatment, and prevention of deleterious mental disorder, mental conditions. These include matters related to cognition, perceptions, Mood (psychology), mood, emotion, and behavior. Initial psychiatric assessment of a person begins with creating a Medical history, case history and conducting a mental status examination. Laboratory tests, physical examinations, and psychological tests may be conducted. On occasion, neuroimaging or neurophysiological studies are performed. Mental disorders are diagnosed in accordance with diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited by the World Health Organization (WHO), and the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013. Treatment may include psychotropics (psychiatric medicines), psychotherapy, su ...

Personality Trait
In psychology, trait theory (also called dispositional 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 behavior, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals (e.g. some people are outgoing whereas others are not), are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions. Traits such as extraversion vs. introversion are measured on a spectrum, with each person placed somewhere along it. Trait theory suggests that some natural behaviours may give someone an advantage in a position of leadership. There are two approaches to define traits: as internal causal properties or as purely descriptive summaries. The internal causal definition states that traits influence our be ...

Temperament And Character Inventory
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. TCI operates with seven dimensions of personality traits: four so-called ''temperaments'' * Novelty seeking (NS) * Harm avoidance (HA) * Reward dependence (RD) * Persistence (PS) and three so-called ''characters'' * Self-directedness (SD) * Cooperativeness (CO) * Self-transcendence (ST) Each of these traits has a varying number of subscales. The dimensions are determined from a 240-item questionnaire. The TCI is based on a psychobiological model that attempts to explain the underlying causes of individual differences in personality traits. Versions Originally developed in English, TCI has been translated to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tridimensional Personality Questionnaire
Tridimensional Personality Questionnaire (TPQ) is a personality test. It was devised by C. Robert Cloninger. A newer version of the questionnaire is called Temperament and Character Inventory. As the name indicates TPQ seeks to measure three dimensions (traits) of the personality. These personality traits are novelty seeking, harm avoidance and reward dependence. Each have four subscales. There are 100 true-false questions which form the basis for the computation of the traits. The personality test also exists in Chinese, French and German versions. Neurobiology Cloninger suggested that the three dimensions, novelty seeking, harm avoidance, and reward dependence, were correlated with low basal dopaminergic activity, high serotonergic activity, and low basal noradrenergic activity, respectively. Much research has gone into examining these links, e.g., with personality genetics. References Other * {{Cite journal , author = C. R. Cloninger , title = A systematic met ...

Neuroticism
Neuroticism is a personality trait associated with negative emotions. It is one of the Big Five traits. Individuals with high scores on neuroticism are more likely than average to experience such feelings as anxiety, worry, fear, anger, shame, frustration, envy, jealousy, pessimism, 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. Their behavioral responses may include procrastination, substance use, and other maladaptive behaviors, which may temporarily aid in relieving negative emotions and in generating positive ones. People with high scores on the neuroticism index are thought to be at risk of developing common mental disorders ( mood disorders, anxiety disorders, and substance use disorders have been studied), and the sorts of symptoms once referred to as " neuroses". Individuals who score low in neu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extraversion
Extraversion and introversion are a central trait dimension in human personality theory. The terms were introduced into psychology by Carl Jung, though both the popular understanding and current psychological usage are not the same as Jung's original concept. Extraversion (also spelled ''extroversion'') is typically associated with sociability, talkativeness, and high energy, while introversion is linked to introspection, reserve, and a preference for solitary activities. 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". While often presented as opposite ends of a single continuum, many personality theorists, such as Carl Jung, have suggested that most individuals possesses elements of both traits, with one being more dominant. Jung provides a different perspective and suggests that everyone has bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revised NEO Personality Inventory
The Revised NEO Personality Inventory (NEO PI-R) is a personality inventory that assesses an individual on five dimensions of personality. These are the same dimensions found in the Big Five personality traits. These traits are openness to experience, conscientiousness, extraversion (-introversion), agreeableness, and neuroticism. In addition, the NEO PI-R also reports on six subcategories of each Big Five personality trait (called facets). Historically, development of the Revised NEO PI-R began in 1978 when Paul Costa and Robert McCrae published a personality inventory. The researchers later published three updated versions of their personality inventory in 1985, 1992, and 2005. These were called the NEO PI (Neuroticism, Extraversion, Openness Personality Inventory), NEO PI-R (or Revised NEO PI), and NEO PI-3, respectively. The revised inventories feature updated vocabulary that could be understood by adults of any education level, as well as children. The inventories hav ...

Eysenck Personality Questionnaire
In psychology, the Eysenck Personality Questionnaire (EPQ) is a questionnaire to assess the personality traits of a person. It was devised by psychologists Hans Jürgen Eysenck and Sybil B. G. Eysenck. Hans Eysenck's theory is based primarily on physiology and genetics. Although he was a behaviorist who considered learned habits of great importance, he believed that personality differences are determined by genetic inheritance. He is, therefore, primarily interested in temperament. In devising a temperament-based theory, Eysenck did not exclude the possibility that some aspects of personality are learned, but left the consideration of these to other researchers. Dimensions Eysenck initially conceptualized personality as two biologically based independent dimensions of temperament, ''E'' and ''N'', measured on a continuum, but then extending this to include a third, ''P''. E – Extraversion/Introversion: Extraversion is characterized by being outgoing, talkative, high on posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conscientiousness
Conscientiousness is the personality trait of being responsible, :wikt:careful, careful, or :wikt:diligent, diligent. Conscientiousness implies a desire to do a task well, and to take obligations to others seriously. Conscientious people tend to be Efficiency, efficient and organized as opposed to Relaxation (psychology), easy-going and :wikt:disorderly, disorderly. They tend to show self-discipline, act Duty, dutifully, and need for achievement, aim for achievement; they display Planning, planned rather than spontaneous behavior; and they are generally dependable. Conscientiousness manifests in characteristic behaviors such as being neat, :wikt:systematic, systematic, :wikt:carefulness, careful, :wikt:thoroughness, thorough, and :wikt:deliberate, deliberate (tending to think carefully before acting). Conscientiousness is one of the five traits of both the Big Five personality traits, Five Factor Model and the HEXACO model of personality structure, HEXACO model of personality and ...

Openness To Experience
Openness to experience is one of the domains which are used to describe personality psychology, human personality in the Big Five personality traits, Five Factor Model. Openness involves six Facet (psychology), facets, or dimensions: active imagination (fantasy), aesthetic sensitivity, attentiveness to inner feelings, preference for variety (adventurousness), intellectual curiosity, and challenging authority (psychological liberalism). 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. Openness tends to be Normal distribution, normally distributed, with a small number of people scoring extremely high or low on the trait and most people scoring moderately. People who score low on openness are considered to be ''closed to experience''. They tend to be conventional and traditiona ...

Five Factor Model
In personality psychology and psychometrics, the Big 5 or five-factor model (FFM) is a widely-used scientific model for describing how personality traits differ across people using five distinct factors: * ''openness'' (''O'') measures creativity, curiosity, and willingness to entertain new ideas. * ''conscientiousness'' (''C'') measures self-control, diligence, and attention to detail. * ''extraversion'' (''E'') measures boldness, energy, and social interactivity. * '' amicability'' or ''agreeableness'' (''A'') measures kindness, helpfulness, and willingness to cooperate. * ''neuroticism'' (''N'') measures depression, irritability, and moodiness. These traits are not black and white; each one is a spectrum, with personality varying continuously across each of these dimensions (unlike in the MBTI inventory). The five-factor model was among the first personality models in psychology derived from empirical research into natural-language data which found consistent correlati ...

Asthenia
Weakness is a symptom of many different medical conditions. The causes are many and can be divided into conditions that have true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis. Pathophysiology Muscle cells work by detecting a flow of electrical impulses from the brain, which signals them to contract through the release of calcium by the sarcoplasmic reticulum. Fatigue (reduced ability to generate force) may occur due to the nerve, or within the muscle cells themselves. New research from scientists at Columbia University suggests that muscle fatigue is caused by calcium leaking out of the muscle cell. This makes less calcium available for the muscle cell. In addition, the Columbia researchers propose that an enzyme activated by this released calcium eats away at muscle fibers. Su ...
