Wechsler Test Of Adult Reading
The Wechsler Test of Adult Reading (WTAR) is a neuropsychological assessment tool used to provide a measure of premorbid intelligence, the degree of Intellectual function prior to the onset of illness or disease.Holdnack, H.A. (2001). Wechsler Test of Adult Reading: WTAR. San Antonio. The Psychological Corporation Test Design Developed for use with English-speaking patients aged 16 to 89 years, WTAR is a “hold” test, a type of neuropsychological test that relies on abilities thought to be unaffected by cognitive decline associated with neurological damage. In the design of WTAR, the demographic prediction tables were co-normed with the widely used Wechsler Adult Intelligence Scale (WAIS) and Wechsler Memory Scale (WMS). This gives it an advantage for comparative analyses on predicted and actual general intellectual and memory function over similar reading tests such as the National Adult Reading Test (NART), which do not share normative data sets with the other widely use ...

Neuropsychological Test
Neuropsychological tests are specifically designed tasks that are used to measure a psychological function known to be linked to a particular brain structure or pathway. Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits. They usually involve the systematic administration of clearly defined procedures in a formal environment. Neuropsychological tests are typically administered to a single person working with an examiner in a quiet office environment, free from distractions. As such, it can be argued that neuropsychological tests at times offer an estimate of a person's peak level of cognitive performance. Neuropsychological tests are a core component of the process of conducting neuropsychological assessment, along with personal, interpersonal and contextual factors. Most neuropsychological tests in current use are based on traditional psychometric theory. In this model, a person's raw score on a test is compared to a large gen ...

Premorbid
Premorbidity refers to the state of functionality prior to the onset of a disease or illness. It is most often used in relation to psychological function (e.g. premorbid personality or premorbid intelligence), but can also be used in relation to other medical conditions (e.g. premorbid lung function or premorbid heart rate). Psychology In psychology, premorbidity is most often used in relation to changes in personality, intelligence or cognitive function. Changes in personality are common in cases of traumatic brain injury involving the frontal lobes, the most famous example of this is the case of Phineas Gage who survived having a tamping iron shot through his head in a railway construction accident. Declines from premorbid levels of intelligence and other cognitive functions are observed in stroke, traumatic brain injury, and dementia as well as in mental illnesses such as depression and schizophrenia. Other usage in psychology include premorbid adjustment which has important ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Intelligence
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. More generally, it can be described as the ability to perceive or infer information, and to retain it as knowledge to be applied towards adaptive behaviors within an environment or context. Intelligence is most often studied in humans but has also been observed in both non-human animals and in plants despite controversy as to whether some of these forms of life exhibit intelligence. Intelligence in computers or other machines is called artificial intelligence. Etymology The word ''intelligence'' derives from the Latin nouns '' intelligentia'' or '' intellēctus'', which in turn stem from the verb '' intelligere'', to comprehend or perceive. In the Middle Ages, the word ''intellectus'' became the scholarly technical term for understanding, and a translation f ...

Intellectual Function
Intellectual functioning refers to the "general mental ability that includes reasoning, planning, problem solving, abstract thinking, comprehending complex ideas, learning quickly and learning from experience". Significantly limited or impaired intellectual functioning characterizes intellectual disabilities. Ageing has been shown to cause a decline in intellectual functioning. See also * Human intelligence * Intellectual disability * Emotional or behavioral disability * Borderline intellectual functioning * American Association on Intellectual and Developmental Disabilities The American Association on Intellectual and Developmental Disabilities (AAIDD) is an American non-profit organization focusing on intellectual disability and related developmental disabilities.

Hold Test
Hold tests are neuropsychological tests which measure abilities which are thought to be largely resistant to cognitive decline following neurological damage. As a result, these tests are widely used for estimating premorbid intelligence in conditions such as dementia, traumatic brain injury, and stroke. Usage In neuropsychological assessment it is important to be able to accurately estimate premorbid intelligence. Accurate estimation allows the quantification of the impacts of neurological damage or decline, when compared to tests of current intelligence. The magnitude of decline is important for prognosis, rehabilitation planning and financial compensation. Hold tests used Hold tests typically measure crystallised intelligence, that is stored knowledge and skills, such as vocabulary and pronunciation. Of course, hold tests of abilities directly affected by neurological damage are likely to underestimate intelligence. For example, using reading tests in patients with aphasia. Ex ...

Wechsler Adult Intelligence Scale
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 ...

Wechsler Memory Scale
The Wechsler Memory Scale (WMS) is a neuropsychological test designed to measure different memory functions in a person. Anyone ages 16 to 90 is eligible to take this test. The current version is the fourth edition (WMS-IV) which was published in 2009 and which was designed to be used with the WAIS-IV. A person's performance is reported as five Index Scores: Auditory Memory, Visual Memory, Visual Working Memory, Immediate Memory, and Delayed Memory. The WMS-IV also incorporates an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess global cognitive functioning in people with suspected memory deficits or those who have been diagnosed with a various neural, psychiatric and/or developmental disorders. This may include conditions such as dementias or mild learning difficulties. There is clear evidence that the WMS differentiates clinical groups (such as those with dementias or neurological disorders) from those with normal memory functioning and that the primary ...

National Adult Reading Test
The National Adult Reading Test (NART) is a widely accepted and commonly used method in clinical settings for estimating premorbid intelligence levels of English-speaking patients with dementia in neuropsychological research and practice. Such tests are called hold tests as these abilities are thought to be spared, or "held" following neurological injury or decline. The NART was developed by Hazel Nelson in the 1980s in Britain and published in 1982. The test comprises 50 written words in British English which all have irregular spellings (e.g. "aisle"), so as to test the participant's vocabulary rather than their ability to apply regular pronunciation rules. The manual includes equations for converting NART scores to predicted IQ scores on the Wechsler Adult Intelligence Scale. The NART is widely used in research settings because a measure of premorbid intelligence is rarely available. However, the Lothian Birth Cohort Study has such data. Researchers from this study demonstra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Grapheme
In linguistics, a grapheme is the smallest functional unit of a writing system. The word ''grapheme'' is derived and the suffix ''-eme'' by analogy with ''phoneme'' and other names of emic units. The study of graphemes is called ''graphemics''. The concept of graphemes is abstract and similar to the notion in computing of a Character (computing), character. By comparison, a specific shape that represents any particular grapheme in a given typeface is called a glyph. Conceptualization There are two main opposing grapheme concepts. In the so-called ''referential conception'', graphemes are interpreted as the smallest units of writing that correspond with sounds (more accurately phonemes). In this concept, the ''sh'' in the written English word ''shake'' would be a grapheme because it represents the phoneme Voiceless postalveolar fricative, /ʃ/. This referential concept is linked to the ''dependency hypothesis'' that claims that writing merely depicts speech. By contrast, t ...

Phoneme
In phonology and linguistics, a phoneme () is a unit of sound that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west of England, the sound patterns (''sin'') and (''sing'') are two separate words that are distinguished by the substitution of one phoneme, , for another phoneme, . Two words like this that differ in meaning through the contrast of a single phoneme form a ''minimal pair''. If, in another language, any two sequences differing only by pronunciation of the final sounds or are perceived as being the same in meaning, then these two sounds are interpreted as phonetic variants of a single phoneme in that language. Phonemes that are established by the use of minimal pairs, such as ''tap'' vs ''tab'' or ''pat'' vs ''bat'', are written between slashes: , . To show pronunciation, linguists use square brackets: (indicating an aspirated ''p'' in ''p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Traumatic Brain Injury
A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity (ranging from mild traumatic brain injury TBI/concussionto severe traumatic brain injury), mechanism ( closed or penetrating head injury), or other features (e.g., occurring in a specific location or over a widespread area). Head injury is a broader category that may involve damage to other structures such as the scalp and skull. TBI can result in physical, cognitive, social, emotional and behavioral symptoms, and outcomes can range from complete recovery to permanent disability or death. Causes include falls, vehicle collisions and violence. Brain trauma occurs as a consequence of a sudden acceleration or deceleration within the cranium or by a complex combination of both movement and sudden impact. In addition to the damage caused at the moment of injury, a variety of events following the injury may result in ...
