Arthur Robert Jensen was an American psychologist and writer. He was a professor of educational psychology at the University of California, Berkeley. Jensen was known for his work in psychometrics and differential psychology, the study of how and why individuals differ behaviorally from one another.
An intelligence quotient (IQ) is a total score derived from a set of standardised tests or subtests designed to assess human intelligence. The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book.
Differential psychology studies the ways in which individuals differ in their behavior and the processes that underlie it. It is a discipline that develops classifications (taxonomies) of psychological individual differences. This is distinguished from other aspects of psychology in that, although psychology is ostensibly a study of individuals, modern psychologists often study groups, or attempt to discover general psychological processes that apply to all individuals. This particular area of psychology was first named and still retains the name of "differential psychology" by William Stern in his 1900 book "Über Psychologie der individuellen Differenzen".
Emotional intelligence (EI) is 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.
Creativity is the ability to form novel and valuable ideas or works using the imagination. Products of creativity may be intangible or a physical object. Creativity may also describe the ability to find new solutions to problems, or new methods of performing a task or reaching a goal. Creativity therefore enables people to solve problems in new or innovative ways.
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason. Human intelligence is also thought to encompass their capacities to recognize patterns, plan, innovate, solve problems, make decisions, retain information, and use language to communicate.
The g factor is a construct developed in psychometric investigations of cognitive abilities and human intelligence. It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the fact that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks. The g factor typically accounts for 40 to 50 percent of the between-individual performance differences on a given cognitive test, and composite scores based on many tests are frequently regarded as estimates of individuals' standing on the g factor. The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. However, the g factor itself is a mathematical construct indicating the level of observed correlation between cognitive tasks. The measured value of this construct depends on the cognitive tasks that are used, and little is known about the underlying causes of the observed correlations.
Conscientiousness is the personality trait of being responsible, 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 tend to show self-discipline, act dutifully, and aim for achievement; they display planned rather than spontaneous behavior; and they are generally dependable. Conscientiousness manifests in characteristic behaviors such as being neat, systematic, careful, thorough, and deliberate.
In trait theory, the Big Five personality traits are a group of five unique characteristics used to study personality:
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.
Employment testing is the practice of administering written, oral, or other tests as a means of determining the suitability or desirability of a job applicant. The premise is that if scores on a test correlate with job performance, then it is economically useful for the employer to select employees based on scores from that test.
In social psychology, illusory superiority is a cognitive bias wherein people overestimate their own qualities and abilities compared to others. Illusory superiority is one of many positive illusions, relating to the self, that are evident in the study of intelligence, the effective performance of tasks and tests, and the possession of desirable personal characteristics and personality traits. Overestimation of abilities compared to an objective measure is known as the overconfidence effect.
Job performance assesses whether a person performs a job well. Job performance, studied academically as part of industrial and organizational psychology, also forms a part of human resources management. Performance is an important criterion for organizational outcomes and success. John P. Campbell describes job performance as an individual-level variable, or something a single person does. This differentiates it from more encompassing constructs such as organizational performance or national performance, which are higher-level variables.
In psychology, grit is a positive, non-cognitive trait based on a person's perseverance of effort combined with their passion for a particular long-term goal or end state. This perseverance of effort helps people overcome obstacles or challenges to accomplishment and drives people to achieve.
Typical intellectual engagement (TIE) is a personality construct referring to a person's enjoyment of intellectually demanding activities. TIE was developed to identify aspects of personality most closely related to intelligence and knowledge and measures a person's typical performance in intellectual domains rather than their maximal performance. TIE is moderately positively associated with crystallized intelligence, and with general knowledge, and predicts academic performance. TIE is hard to distinguish from the earlier construct need for cognition and is positively correlated with openness to experience.
The psychology of music preference is the study of the psychological factors behind peoples' different music preferences. One study found that after researching through studies from the past 50 years, there are more than 500 functions for music. Music is heard by people daily in many parts of the world, and affects people in various ways from emotional regulation to cognitive development, along with providing a means for self-expression. Music training has been shown to help improve intellectual development and ability, though minimal connection has been found as to how it affects emotion regulation. Numerous studies have been conducted to show that individual personality can have an effect on music preference, though a recent meta-analysis has shown that personality in itself explains little variance in music preferences. These studies are not limited to American culture, as they have been conducted with significant results in countries all over the world, including Japan, Germany, Spain, and Brazil.
Sex differences in human intelligence have long been a topic of debate among researchers and scholars. It is now recognized that there are no significant sex differences in average IQ, though particular subtypes of intelligence vary somewhat between sexes.
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.
Intellectual curiosity is curiosity that leads to an acquisition of general knowledge. It can include curiosity about such things as what objects are composed of, the underlying mechanisms of systems, mathematical relationships, languages, social norms, and history. It can be differentiated from another type of curiosity that does not lead to the acquisition of general knowledge, such as curiosity about the intimate secrets of other people. It is a facet of openness to experience in the Five Factor Model used to describe human personalities. It is similar to need for cognition and typical intellectual engagement.
