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 ...

Cognitive
Cognition refers to "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, 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. Imagination is also a cognitive process, it is considered as such because it involves thinking about possibilities. Cognitive processes use existing knowledge and discover new knowledge. Cognitive processes are analyzed from different perspectives within different contexts, notably in the fields of linguistics, musicology, anesthesia, neuroscience, psychiatry, psychology, education, philosophy, anthropology, biology, systemics, logic, and computer science. These and other approaches to the analysis of cognition (such as embodied cognition) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Language
Language is a structured system of communication. The structure of a language is its grammar and the free components are its vocabulary. Languages are the primary means by which humans communicate, and may be conveyed through a variety of methods, including spoken, sign, and written language. Many languages, including the most widely-spoken ones, have writing systems that enable sounds or signs to be recorded for later reactivation. Human language is highly variable between cultures and across time. Human languages have the properties of productivity and displacement, and rely on social convention and learning. Estimates of the number of human languages in the world vary between and . Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are spoken, signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing, whi ...

Visual
The visual system comprises the sensory organ (the eye) and parts of the central nervous system (the retina containing photoreceptor cells, the optic nerve, the optic tract and the visual cortex) which gives organisms the sense of sight (the ability to detect and process visible light) as well as enabling the formation of several non-image photo response functions. It detects and interprets information from the optical spectrum perceptible to that species to "build a representation" of the surrounding environment. The visual system carries out a number of complex tasks, including the reception of light and the formation of monocular neural representations, colour vision, the neural mechanisms underlying stereopsis and assessment of distances to and between objects, the identification of a particular object of interest, motion perception, the analysis and integration of visual information, pattern recognition, accurate motor coordination under visual guidance, and more. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Working Memory
Working memory is a cognitive system with a limited capacity that can hold information temporarily. It is important for reasoning and the guidance of decision-making and behavior. Working memory is often used synonymously with short-term memory, but some theorists consider the two forms of memory distinct, assuming that working memory allows for the manipulation of stored information, whereas short-term memory only refers to the short-term storage of information. Working memory is a theoretical concept central to cognitive psychology, neuropsychology, and neuroscience. History The term "working memory" was coined by Miller, Galanter, and Pribram, and was used in the 1960s in the context of theories that likened the mind to a computer. In 1968, Atkinson and Shiffrin used the term to describe their "short-term store". What we now call working memory was formerly referred to variously as a "short-term store" or short-term memory, primary memory, immediate memory, operant memo ...

Visual Recognition
Computer vision is an interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to understand and automate tasks that the human visual system can do. Computer vision tasks include methods for acquiring, processing, analyzing and understanding digital images, and extraction of high-dimensional data from the real world in order to produce numerical or symbolic information, e.g. in the forms of decisions. Understanding in this context means the transformation of visual images (the input of the retina) into descriptions of the world that make sense to thought processes and can elicit appropriate action. This image understanding can be seen as the disentangling of symbolic information from image data using models constructed with the aid of geometry, physics, statistics, and learning theory. The scientific discipline of computer vision is concerned with the theory be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonological Processing
Phonology is the branch of linguistics that studies how languages or dialects systematically organize their sounds or, for sign languages, their constituent parts of signs. The term can also refer specifically to the sound or sign system of a particular language variety. At one time, the study of phonology related only to the study of the systems of phonemes in spoken languages, but may now relate to any linguistic analysis either: Sign languages have a phonological system equivalent to the system of sounds in spoken languages. The building blocks of signs are specifications for movement, location, and handshape. At first, a separate terminology was used for the study of sign phonology ('chereme' instead of 'phoneme', etc.), but the concepts are now considered to apply universally to all human languages. Terminology The word 'phonology' (as in 'phonology of English') can refer either to the field of study or to the phonological system of a given language. This is one of th ...

Harcourt Assessment
Harcourt Assessment was a company that published and distributed educational and psychological assessment tools and therapy resources and provided educational assessment and data management services for national, state, district and local assessments. On January 30, 2008, Harcourt Assessment was merged into Pearson PLC, Pearson's Pearson Assessment & Information, Assessment & Information group after being acquired from Reed Elsevier for $950 million. History Harcourt Assessment's history dates to the early part of the 20th century. Although the company name derives from Harcourt Trade Publishers, Harcourt Brace & Company, which was established in 1919, the corporate heritage goes back to 1905 and the founding of World Book Company. Many of the educational products produced by Harcourt Assessment originated at World Book. The psychological assessments originated at The Psychological Corporation, which was founded in 1921.

Intellectual Giftedness
Intellectual giftedness is an intellectual ability significantly higher than average. It is a characteristic of children, variously defined, that motivates differences in school programming. It is thought to persist as a trait into adult life, with various consequences studied in longitudinal studies of giftedness over the last century. There is no generally agreed definition of giftedness for either children or adults, but most school placement decisions and most longitudinal studies over the course of individual lives have followed people with IQs in the top 2.5 percent of the population—that is, IQs above 130. Definitions of giftedness also vary across cultures. The various definitions of intellectual giftedness include either general high ability or specific abilities. For example, by some definitions, an intellectually gifted person may have a striking talent for mathematics without equally strong language skills. In particular, the relationship between artistic ability ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-IQ Society
A high-IQ society is an organization that limits its membership to people who have attained a specified score on an IQ test, usually in the top two percent of the population (98th percentile) or above. These may also be referred to as genius societies. The largest and oldest such society is Mensa International, which was founded by Roland Berrill and Lancelot Ware in 1946. Entry requirements High-IQ societies typically accept a variety of IQ tests for membership eligibility; these include WAIS, Stanford-Binet, and Raven's Advanced Progressive Matrices, amongst many others deemed to sufficiently measure or correlate with intelligence. Tests deemed to insufficiently correlate with intelligence (e.g. post-1994 SAT, in the case of Mensa and Intertel) are not accepted for admission. As IQ significantly above 146 SD15 (approximately three-sigma) cannot be reliably measured with accuracy due to sub-test limitations and insufficient norming, IQ societies with cutoffs significantly h ...

Intertel
Intertel (previously the International Legion of Intelligence) is a high-IQ society founded in 1966, that is open to those who have scored at or above the 99th percentile (top 1%) on one of various standardized tests of intelligence. It has been identified as one of the notable high-IQ societies established since the late 1960s with admissions requirements that are stricter and more exclusive than Mensa. History and goals Intertel was founded in 1966 by Ralph Haines, following the example of Roland Berrill and Lancelot Ware (founders of Mensa), who wanted to create an association adapted to the gifted needs without any specific restriction of admission (with the exception of a minimum IQ). Intertel thus became the second oldest organization of this kind, Mensa being the first. The name "Intertel" derives from ''International Legion of Intelligence,'' and its members are still known as "Ilians". The organizations has three purposes, stated in its constitution: * Encouragin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mensa International
Mensa is the largest and oldest high-IQ society in the world. It is a non-profit organisation open to people who score at the 98th percentile or higher on a standardised, supervised IQ or other approved intelligence test. Mensa formally comprises national groups and the umbrella organisation Mensa International, with a registered office in Caythorpe, Lincolnshire, England, which is separate from the British Mensa office in Wolverhampton. The word ''mensa'' (, ) is Latin for 'table', as is symbolised in the organisation's logo, and was chosen to demonstrate the round-table nature of the organisation; the coming together of equals. History Roland Berrill, an Australian barrister, and Lancelot Ware, a British scientist and lawyer, founded Mensa at Lincoln College, in Oxford, England in 1946, with the intention of forming a society for the most intelligent, with the only qualification being a high IQ. The society was ostensibly to be non-political in its aims, and free from all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
