Cross Battery Assessment
Cross-battery assessment is the process by which psychologists use information from multiple test batteries (i.e., various IQ tests) to help guide diagnostic decisions and to gain a fuller picture of an individual's cognitive abilities than can be ascertained through the use of single-battery assessments. The cross-battery approach (XBA) was first introduced in the late 1990s by Dawn Flanagan, Samuel Ortiz and Kevin McGrew. It offers practitioners the means to make systematic, valid and up-to-date interpretations of intelligence batteries and to augment them with other tests in a way that is consistent with the empirically supported Cattell–Horn–Carroll (CHC) theory of cognitive abilities.Flanagan, D. P., Ortiz, S. O., & Alfonso, V. C. (2007). Essentials of Cross Battery Assessment 2nd Edition. New Jersey: Wiley Three Foundational Sources of Information The XBA approach is a time efficient method to reliably measure a wider (or more in-depth but selective range) of cognitiv ...

Psychologist
A psychologist is a professional who practices psychology and studies mental states, perceptual, cognitive, emotional, and social processes and behavior. Their work often involves the experimentation, observation, and interpretation of how individuals relate to each other and to their environments. Psychologists usually acquire a bachelor's degree in psychology, followed by a master's degree or doctorate in psychology. Unlike psychiatric physicians and psychiatric nurse-practitioners, psychologists usually cannot prescribe medication, but depending on the jurisdiction, some psychologists with additional training can be licensed to prescribe medications; qualification requirements may be different from a bachelor's degree and master's degree. Psychologists receive extensive training in psychological testing, scoring, interpretation, and reporting, while psychiatrists are not usually trained in psychological testing. Psychologists are also trained in, and often specialise in, on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Ability Scales
The Differential Ability Scales (DAS) is a nationally normed (in the US), and individually administered battery of cognitive and achievement tests. Into its second edition (DAS-II), the test can be administered to children ages 2 years 6 months to 17 years 11 months across a range of developmental levels. The diagnostic subtests measure a variety of cognitive abilities including verbal and visual working memory, immediate and delayed recall, visual recognition and matching, processing and naming speed, phonological processing, and understanding of basic number concepts. The original DAS was developed from the BAS ''British Ability Scales'' both by Colin D. Elliot and published by Harcourt Assessment in 1990. Test Structure The DAS-II consists of 20 cognitive subtests which include 17 subtests from the original DAS. The subtests are grouped into the Early Years and School-Age cognitive batteries with subtests that are common to both batteries and those that are unique to each b ...

FSIQ
The Wechsler Adult Intelligence Scale (WAIS) is an IQ test designed to measure intelligence and cognitive ability in adults and older adolescents. The original WAIS (Form I) was published in February 1955 by David Wechsler, as a revision of the Wechsler–Bellevue Intelligence Scale, released in 1939. It is currently in its fourth edition (''WAIS-IV'') released in 2008 by Pearson, and is the most widely used IQ test, for both adults and older adolescents, in the world. History The WAIS is founded on Wechsler's definition of intelligence, which he defined as "... the global capacity of a person to act purposefully, to think rationally, and to deal effectively with his environment." He believed that intelligence was made up of specific elements that could be isolated, defined, and subsequently measured. However, these individual elements were not entirely independent, but were all interrelated. His argument, in other words, is that general intelligence is composed of various speci ...

Deviation (statistics)
In mathematics and statistics, deviation is a measure of difference between the observed value of a variable and some other value, often that variable's mean. The sign of the deviation reports the direction of that difference (the deviation is positive when the observed value exceeds the reference value). The magnitude of the value indicates the size of the difference. Types A deviation that is a difference between an observed value and the ''true value'' of a quantity of interest (where ''true value'' denotes the Expected Value, such as the population mean) is an error. A deviation that is the difference between the observed value and an ''estimate'' of the true value (e.g. the sample mean; the Expected Value of a sample can be used as an estimate of the Expected Value of the population) is a residual. These concepts are applicable for data at the interval and ratio levels of measurement. Unsigned or absolute deviation In statistics, the absolute deviation of an element of a ...

Ipsative
In psychology, ipsative questionnaires (; from Latin: ''ipse'', 'of the self') are those where the sum of scale scores from each respondent adds to a constant value. Sometimes called a forced-choice scale, this measure contrasts Likert-type scales in which respondents score—often from 1 to 5—how much they agree with a given statement (see also norm-referenced test). In psychology While mean scores from Likert-type scales can be compared across individuals, scores from an ipsative measure cannot. To explain, if an individual was equally extroverted and conscientious and was assessed on a Likert-type scale, each trait would be evaluated singularly, i.e. respondents would see the item "I enjoy parties" and agree or disagree with it to whatever degree reflected their preferences. If the same traits were evaluated on an ipsative measure, respondents would be forced to choose between the two, i.e. a respondent would see the item "Which of these do you agree with more strongly? a ...

Underachievement
An underachiever is a person who fails to achieve their potential or does not do as well as expected by their peers. Of particular interest is academic underachievement. Studies of individuals who have not realized their apparent potential have identified learning disabilities, ADHD, and many other educational problems, and subsequently enabled methods of addressing these problems. Current theories among academic scholars prefer to address underperformance problems with remedial help. The term is also used more generally; for example, a sports team that contains many star players but still loses games against teams with relatively little obvious talent might be termed underachieving. A stock which achieves poor profit and/or capital gains despite sound underlying business and/or assets may be called underachieving.

Specific Learning Disability
Learning disability, learning disorder, or learning difficulty (British English) is a condition in the brain that causes difficulties comprehending or processing information and can be caused by several different factors. Given the "difficulty learning in a typical manner", this does not exclude the ability to learn in a different manner. Therefore, some people can be more accurately described as having a "learning difference", thus avoiding any misconception of being disabled with a lack of ability to learn and possible negative stereotyping. In the United Kingdom, the term "learning disability" generally refers to an intellectual disability, while difficulties such as dyslexia and dyspraxia are usually referred to as "learning difficulties". While ''learning disability'' and ''learning disorder'' are often used interchangeably, they differ in many ways. Disorder refers to significant learning problems in an academic area. These problems, however, are not enough to warrant a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychometric
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of Latent variable, latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, Mental disorder, mental disorders, and Educational measurement, educational achievement. The levels of individuals on nonobservable latent variables are Statistical inference, inferred through mathematical model, mathematical modeling based on what is observed from individuals' responses to items on tests and scales. Practitioners are described as psychometricians, although not all who engage in psychometric research go by this title. Psychometricians usually possess specific qualifications such as degrees or certifications, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaufman Assessment Battery For Children
The Kaufman Assessment Battery for Children (KABC) is a clinical instrument (psychological diagnostic test) 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 KABC also gives special attention to certain emerging testing needs, such as use with handicapped groups, application to problems of learning disabilities, and appropriateness for cultural and linguistic minorities. The authors rightly caution, however, that success in meeting these special needs must be judged through practical use over time. They also point out that the KABC should not be regarded as "the complete test b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IQ Test
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. The abbreviation "IQ" was coined by the psychologist William Stern (psychologist), William Stern for the German language, German term ''Intelligenzquotient'', his term for a scoring method for intelligence tests at University of Wrocław, University of Breslau he advocated in a 1912 book. Historically, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score. For modern Intelligence quotient#Current tests, IQ tests, the Test score, raw score is Data transformation (statistics), transformed to a normal distribution with mean 100 and standard deviation 15. This results in approximately two-thirds of the population scoring between I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanford–Binet Intelligence Scales
The Stanford–Binet Intelligence Scales (or more commonly the Stanford–Binet) is an individually-administered intelligence test that was revised from the original Binet–Simon Scale by Alfred Binet and Theodore Simon. The Stanford–Binet Intelligence Scale is now in its fifth edition (SB5), which 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 development of the Stanford–Binet initiated the modern field of intelligence testing and was one of the first examples of an adaptive test. The test originated in France, then was revised in the United States. It was initially created by the French psychologist Alfred Binet, who, following the introdu ...

Woodcock–Johnson Tests Of Cognitive Abilities
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 (although Johnson's contribution is disputed). 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 (with norms utilizing individuals in their 90s). The previous edition WJ III was praised for covering "a wide variety of cognitive skills". Content of the tests The Woodcock-Johnson III Tests of Cognitive Abilities include both the Standard Battery and the Extended Battery. The Standard Battery consists of tests 1 through 10 while the Extended Battery includes tests 11 through 20. There is also a Woodcock-Johnson III Diagnostic Supplement to the Tests of Cognitive Abilities with an additional 11 cognitive tests. All of which combined allows for a considerably detailed analysis of cogn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
