Emotional intelligence (EI) is most often defined as the ability to perceive, use, understand, manage, and handle emotions. People with high emotional intelligence can recognize their own emotions and those of others, use emotional information to guide thinking and behavior, discern between different feelings and label them appropriately, and adjust emotions to adapt to environments. Although the term first appeared in 1964, it gained popularity in the 1995 best-selling book Emotional Intelligence, written by science journalist Daniel Goleman. Goleman defined EI as the array of skills and characteristics that drive leadership performance.
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.
Perfectionism, in psychology, is a broad personality style characterized by a person's concern with striving for flawlessness and perfection and is accompanied by critical self-evaluations and concerns regarding others' evaluations. It is best conceptualized as a multidimensional and multilayered personality characteristic, and initially some psychologists thought that there were many positive and negative aspects. Perfectionism drives people to be concerned with achieving unattainable ideals or unrealistic goals that often lead to many forms of adjustment problems such as depression, anxiety, OCD, OCPD and low self-esteem. These adjustment problems often lead to suicidal thoughts and tendencies and influence or invite other psychological, physical, social, and further achievement problems in children, adolescents, and adults. Although perfectionist sights can reduce stress, anxiety, and panic, recent data, compiled by British psychologists Thomas Curran and Andrew Hill, show that perfectionistic tendencies are on the rise among recent generations of young people.
Christopher Richard Brand was a British psychological and psychometric researcher who gained media attention for his statements on race and intelligence and paedophilia.
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.
The Barratt Impulsiveness Scale (BIS) is a widely used measure of impulsiveness. It includes 30 items that are scored to yield six first-order factors and three second-order factors.
Cognitive style or thinking style is a concept used in cognitive psychology to describe the way individuals think, perceive and remember information. Cognitive style differs from cognitive ability, the latter being measured by aptitude tests or so-called intelligence tests. There is controversy over the exact meaning of the term "cognitive style" and whether it is a single or multiple dimension of human personality. However it remains a key concept in the areas of education and management. If a pupil has a cognitive style that is similar to that of his/her teacher, the chances are improved that the pupil will have a more positive learning experience. Likewise, team members with similar cognitive styles likely feel more positive about their participation with the team. While matching cognitive styles may make participants feel more comfortable when working with one another, this alone cannot guarantee the success of the outcome.
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.
Timothy C. Bates is a professor of differential psychology at the University of Edinburgh. His research interests include the genetics of reading and spelling, intelligence, and personality.
The Narcissistic Personality Inventory (NPI) was developed in 1979 by Raskin and Hall, and since then, has become one of the most widely utilized personality measures for non-clinical levels of the trait narcissism. Since its initial development, the NPI has evolved from 220 items to the more commonly employed NPI-40 (1984) and NPI-16 (2006), as well as the novel NPI-1 inventory (2014). Derived from the DSM-III criteria for Narcissistic personality disorder (NPD), the NPI has been employed heavily by personality and social psychology researchers.
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".
Manipulation in psychology is a behavior designed to exploit, control, or otherwise influence others to one’s advantage. Definitions for the term vary in which behavior is specifically included, influenced by both culture and whether referring to the general population or used in clinical contexts. Manipulation is generally considered a dishonest form of social influence as it is used at the expense of the others.
Sensation seeking is a personality trait defined by the search for experiences and feelings, that are "varied, novel, complex and intense", and by the readiness to "take physical, social, legal, and financial risks for the sake of such experiences." Risk is not an essential part of the trait, as many activities associated with it are not risky. However, risk may be ignored, tolerated, or minimized and may even be considered to add to the excitement of the activity. The concept was developed by Marvin Zuckerman of the University of Delaware. In order to assess this trait he created a personality test called the Sensation Seeking Scale. This test assesses individual differences in terms of sensory stimulation preferences. So there are people who prefer a strong stimulation and display a behavior that manifests a greater desire for sensations and there are those who prefer a low sensory stimulation. The scale is a questionnaire designed to measure how much stimulation a person requires and the extent to which they enjoy the excitement. Zuckerman hypothesized that people who are high sensation seekers require a lot of stimulation to reach their Optimal Level of Arousal. When the stimulation or sensory input is not met, the person finds the experience unpleasant.
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.
The morningness–eveningness questionnaire (MEQ) is a self-assessment questionnaire developed by researchers James A. Horne and Olov Östberg in 1976. Its main purpose is to measure whether a person's circadian rhythm produces peak alertness in the morning, in the evening, or in between. The original study showed that the subjective time of peak alertness correlates with the time of peak body temperature; morning types have an earlier temperature peak than evening types, with intermediate types having temperature peaks between the morning and evening chronotype groups. The MEQ is widely used in psychological and medical research and has been professionally cited more than 4,000 times.
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.
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.
Reuven Bar-On is an Israeli psychologist and one of the leading pioneers, theorists and researchers in emotional intelligence. Bar-On is thought to be the first to introduce the concept of an “EQ” to measure “emotional and social competence”, although the acronym was used earlier to describe ideas that were not associated with emotional intelligence per se. In the first copy of his doctoral dissertation, which was submitted in 1985, Bar-On proposed a quantitative approach to creating “an EQ analogous to an IQ score”.
The Dark Triad Dirty Dozen (DTDD) is a brief 12-question personality inventory test to assesses the possible presence of three co-morbid socially maladaptive, dark triad traits: Machiavellianism, narcissism, and psychopathy. The DTDD was developed to identify the dark triad traits among subclinical adult populations. It is a screening test. High scores on the DTDD do not necessary correlate with clinical diagnoses.
