The Stanford–Binet Intelligence Scales is an individually administered intelligence test that was revised from the original Binet–Simon Scale by Lewis Terman, a psychologist at Stanford University. The Stanford–Binet Intelligence Scale is now in its fifth edition (SB5) and was released in 2003. It is a cognitive ability and intelligence test that is used to diagnose developmental or intellectual deficiencies in young children. The test measures five weighted factors and consists of both verbal and nonverbal subtests. The five factors being tested are knowledge, quantitative reasoning, visual-spatial processing, working memory, and fluid reasoning.
The concepts of fluid intelligence (gf) and crystallized intelligence (gc) were introduced in 1963 by the psychologist Raymond Cattell. According to Cattell's psychometrically-based theory, general intelligence (g) is subdivided into gf and gc. Fluid intelligence is the ability to solve novel reasoning problems and is correlated with a number of important skills such as comprehension, problem solving, and learning. Crystallized intelligence, on the other hand, involves the ability to deduce secondary relational abstractions by applying previously learned primary relational abstractions.
Cognitive tests are assessments of the cognitive capabilities of humans and other animals. Tests administered to humans include various forms of IQ tests; those administered to animals include the mirror test and the T maze test. Such study is important to research concerning the philosophy of mind and psychology, as well as determination of human and animal intelligence.
The Beck Depression Inventory, created by Aaron T. Beck, is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression. Its development marked a shift among mental health professionals, who had until then, viewed depression from a psychodynamic perspective, instead of it being rooted in the patient's own thoughts.
The Iowa Assessments also known informally as the Iowa Tests or colloquially as ITBS tests, are standardized tests provided as a service to schools by the College of Education of the University of Iowa. Developers Everett Franklin Lindquist, Harry Greene, Ernest Horn, Maude McBroom, and Herbert Spitzer first designed and administered the tests in 1935 as a tool for improving student instruction. The tests are administered to students in kindergarten through eighth grade as part of the Iowa Statewide Testing Programs, a division of the Iowa Testing Programs (ITP). Over decades, participation expanded and currently nearly all school districts in Iowa participate annually in the program, as do many other school districts across the United States. In a cooperative relationship, participating schools receive ITBS test materials, scoring and reporting services and consultation in the use of ITBS for instructional purposes, and ITP utilizes participation by schools in research and test development. Both the ITBS and Iowa Tests of Educational Development (ITED) were revised in the 2011–2012 school year. They were rebranded the Iowa Assessments. In 2016-2017, Iowa Assessments will roll out their new testing program, Next Generation Iowa Assessments.
NEPSY is a series of neuropsychological tests authored by Marit Korkman, Ursula Kirk and Sally Kemp, that are used in various combinations to assess neuropsychological development in children ages 3–16 years in six functional domains. NEPSY was designed to assess both basic and complex aspects of cognition critical to children’s ability to learn and be productive, in and outside of, school settings. It is designed to test cognitive functions not typically covered by general ability or achievement batteries. The original NEPSY was published in 1998 by Pearson Assessment, and was superseded by the NEPSY-II in 2007.
The Kaufman Assessment Battery for Children (KABC) is a clinical instrument for assessing cognitive development. Its construction incorporates several recent developments in both psychological theory and statistical methodology. The test was developed by Alan S. Kaufman and Nadeen L. Kaufman in 1983 and revised in 2004. The test has been translated and adopted for many countries, such as the Japanese version of the K-ABC by the Japanese psychologists Tatsuya Matsubara, Kazuhiro Fujita, Hisao Maekawa, and Toshinori Ishikuma.
The Culture Fair Intelligence Test (CFIT) was created by Raymond Cattell in 1949 as an attempt to measure cognitive abilities devoid of sociocultural and environmental influences. Scholars have subsequently concluded that the attempt to construct measures of cognitive abilities devoid of the influences of experiential and cultural conditioning is a challenging one. Cattell proposed that general intelligence (g) comprises both Fluid Intelligence (Gf) and Crystallized Intelligence (Gc). Whereas Gf is biologically and constitutionally based, Gc is the actual level of a person's cognitive functioning, based on the augmentation of Gf through sociocultural and experiential learning.
The Cattell–Horn–Carroll theory, is a psychological theory on the structure of human cognitive abilities. Based on the work of three psychologists, Raymond B. Cattell, John L. Horn and John B. Carroll, the Cattell–Horn–Carroll theory is regarded as an important theory in the study of human intelligence. Based on a large body of research, spanning over 70 years, Carroll's Three Stratum theory was developed using the psychometric approach, the objective measurement of individual differences in abilities, and the application of factor analysis, a statistical technique which uncovers relationships between variables and the underlying structure of concepts such as 'intelligence'. The psychometric approach has consistently facilitated the development of reliable and valid measurement tools and continues to dominate the field of intelligence research.
IQ classification is the practice by IQ test publishers of labeling IQ score ranges with category names such as "superior" or "average".
The Das–Naglieri cognitive assessment system (CAS) test is an individually administered test of cognitive functioning for children and adolescents ranging from 5 through 17 years of age that was designed to assess the planning, attention, simultaneous and successive cognitive processes as described in the PASS theory of intelligence.
The Cognitive Abilities Test(CogAT) is a group-administered K–12 assessment intended to estimate students' learned reasoning and problem solving abilities through a battery of verbal, quantitative, and nonverbal test items. The test purports to assess students' acquired reasoning abilities while also predicting achievement scores when administered with the co-normed Iowa Tests. The test was originally published in 1954 as the Lorge-Thorndike Intelligence Test, after the psychologists who authored the first version of it, Irving Lorge and R.L. Thorndike.
Raymond S. Dean was an American psychologist who was the George and Frances Ball Distinguished Professor of Neuropsychology and Professor of Psychology at Ball State University.
The Dean-Woodcock Neuropsychological Assessment System (DWNAS) provides a standardized procedure for assessing an individual's sensory, motor, emotional, cognitive, and academic functioning for both English and Spanish speakers, based on the Cattell-Horn-Carroll Model (CHC). The instrument may be administered by psychologists, that need not have neuropsychological backgrounds. It was developed by, and is named after, psychologists Raymond Dean and Richard Woodcock.
The Woodcock–Johnson Tests of Cognitive Abilities is a set of intelligence tests first developed in 1977 by Richard Woodcock and Mary E. Bonner Johnson. It was revised in 1989, again in 2001, and most recently in 2014; this last version is commonly referred to as the WJ IV. They may be administered to children from age two right up to the oldest adults. The previous edition WJ III was praised for covering "a wide variety of cognitive skills".
The Planning, Attention-Arousal, Simultaneous and Successive (PASS) theory of intelligence, first proposed in 1975, and later elaborated by Das, Naglieri & Kirby (1994) and Das, Kar & Parrila, (1996) challenges g-theory on the grounds that the brain is made up of interdependent, but separate, functional systems. Neuroimaging studies and clinical studies of individuals with brain lesions make it clear that the brain is modularized; for example, damage to a very specific area of the left temporal lobe will impair the production of spoken and written language. Damage to an adjacent area will have the opposite impact, preserving the individual's ability to produce, but not understand speech and text.
The Children's Depression Inventory is a psychological assessment that rates the severity of symptoms related to depression or dysthymic disorder in children and adolescents. The CDI is a 27-item scale that is self-rated and symptom-oriented. The assessment is now in its second edition. The 27 items on the assessment are grouped into five major factor areas. Clients rate themselves based on how they feel and think, with each statement being identified with a rating from 0 to 2. The CDI was developed by American clinical psychologist Maria Kovacs, PhD, and was published in 1979. It was developed by using the Beck Depression Inventory (BDI) of 1967 for adults as a model. The CDI is a widely used and accepted assessment for the severity of depressive symptoms in children and youth, with high reliability. It also has a well-established validity using a variety of different techniques, and good psychometric properties. The CDI is a Level B test.
The Multidimensional Aptitude Battery II is a group-administered intelligence test created by psychologist Douglas N. Jackson which is supposed to measure Verbal, Performance and Full Scale IQ. The battery consists of 10 subtests and is used for various professional, medical, military, government, law enforcement and employment settings. The test-retest reliability based on timed performance correlates with values of 0.95 for the verbal section, 0.96 for the performance section and 0.97 for the full scale.
