Douglas K. Detterman (born 1942) [1] is an American psychologist who researches intelligence and intellectual disability. [2]
He earned his B.A. from Boston University in 1967, his M.A. and Ph.D. from University of Alabama in 1972 and was a postdoctoral fellow at Northwestern University in 1972.
Detterman taught at University of Dayton from 1970 to 1972, then took a position at Case Western Reserve University, where he has remained since.
Among his achievements, Detterman founded the scientific journal Intelligence in 1977, and was editor in chief from 1977 to 2016 where it was taken over by Richard Haier. He also founded the International Society for Intelligence Research and was its president until 2011. He has also been a Fellow of the American Psychological Association from 1978 to 1998, a Fellow and charter member of the American Psychological Society from 1990 to 1998, and received a Mensa Research Award in 1991.
In 1995, he was a signatory of a collective statement in response to public discussion of the book The Bell Curve titled "Mainstream Science on Intelligence," [3] written by Intelligence editor Linda Gottfredson and published in The Wall Street Journal and reprinted in Intelligence in 1997. He also collaborated on several books on intelligence with psychologist Robert J. Sternberg.
Detterman has argued that it is unfair to tell people they can accomplish anything if they just put enough practice into it, since they are limited by their abilities. [4] Similarly, he has argued that cognitive training does not increase intelligence, but only one's ability to take tests, and notes the poor quality of studies done by commercial brain training companies (see also Lumosity#Effectiveness and legal history). Instead, he advises parents to save their money. [5]
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.
Cognition is the "mental action or process of acquiring knowledge and understanding through thought, experience, and the senses". It encompasses all aspects of intellectual functions and processes such as: perception, attention, thought, imagination, intelligence, the formation of knowledge, memory and working memory, judgment and evaluation, reasoning and computation, problem-solving and decision-making, comprehension and production of language. Cognitive processes use existing knowledge to discover new knowledge.
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.
Intelligence has been defined in many ways: the capacity for abstraction, logic, understanding, self-awareness, learning, emotional knowledge, reasoning, planning, creativity, critical thinking, and problem-solving. It can be described as the ability to perceive or infer information; and to retain it as knowledge to be applied to adaptive behaviors within an environment or context.
Robert J. Sternberg is an American psychologist and psychometrician. He is a Professor of Human Development at Cornell University.
The Triarchic Theory of Intelligence or Three Forms of Intelligence, formulated by psychologist Robert Sternberg, aims to go against the psychometric approach to intelligence and take a more cognitive approach, which leaves it to the category of the cognitive-contextual theories. The three meta components are also called triarchic components.
Linda Susanne Gottfredson is an American psychologist and writer. She is professor emerita of educational psychology at the University of Delaware and co-director of the Delaware-Johns Hopkins Project for the Study of Intelligence and Society. She is best known for writing the 1994 letter "Mainstream Science on Intelligence", which was published in the Wall Street Journal in defense of Richard Herrnstein and Charles Murray's controversial book The Bell Curve (1994).
Thomas J. Bouchard Jr. is an American psychologist known for his behavioral genetics studies of twins raised apart. He is professor emeritus of psychology and director of the Minnesota Center for Twin and Adoption Research at the University of Minnesota. Bouchard received his PhD from the University of California, Berkeley, in 1966.
Social intelligence is the ability to understand one's own and others' actions. Social intelligence is learned and develops from experience with people and learning from success and failures in social settings. It is an important interpersonal skill that helps individuals succeed in all aspects of their lives.
The International Society for Intelligence Research (ISIR) is a scientific society for researchers in human intelligence. It was founded by Douglas K. Detterman of Case Western Reserve University in 2000.
John Bissell Carroll was an American psychologist known for his contributions to psychology, linguistics and psychometrics.
"Mainstream Science on Intelligence" was a public statement issued by a group of researchers led by psychologist Linda Gottfredson. It was published originally in The Wall Street Journal on December 13, 1994, as a response to criticism of the book The Bell Curve by Richard Herrnstein and Charles Murray, which appeared earlier the same year. The statement defended Herrnstein and Murray's controversial claims about race and intelligence, including the claim that average intelligence quotient (IQ) differences between racial and ethnic groups may be at least partly genetic in origin. This view is now considered discredited by mainstream science.
Douglas Northrop Jackson II was a Canadian psychology professor best known for his work in human assessment and psychological testing.
Zenon Walter Pylyshyn was a Canadian cognitive scientist and philosopher. He was a Canada Council Senior Fellow from 1963 to 1964.
The history of the race and intelligence controversy concerns the historical development of a debate about possible explanations of group differences encountered in the study of race and intelligence. Since the beginning of IQ testing around the time of World War I, there have been observed differences between the average scores of different population groups, and there have been debates over whether this is mainly due to environmental and cultural factors, or mainly due to some as yet undiscovered genetic factor, or whether such a dichotomy between environmental and genetic factors is the appropriate framing of the debate. Today, the scientific consensus is that genetics does not explain differences in IQ test performance between racial groups.
René V. Dawis is an American psychology professor. He taught at University of Minnesota and is currently an emeritus professor. His work focused on individual differences, work adjustment, and human potential. He received the American Psychological Associations's Leona Tyler Award in 1999.
The following outline is provided as an overview of and topical guide to human intelligence:
Human Diversity: The Biology of Gender, Race, and Class is a 2020 non-fiction book written by the American political scientist Charles Murray. In the book, Murray argues against the scientific consensus that race is a social construct, as well as other orthodoxies such as the view that gender is a social construct, and class is a function of privilege.
