Specific language impairment (SLI) is a disorder where the patient has a lack of language acquisition skills, despite a seemingly normal intelligence level in other areas. [12] Stuttering is a fairly common disorder where speech flow is interrupted by involuntary repetitions of syllables .
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, 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.
Though distinct, there is interaction, as fluid intelligence is a determining factor in the speed with which crystallised knowledge is accumulated (Cattell, 1963). Crystallised intelligence is known to increase with age as we accumulate knowledge throughout the lifespan. Fluid processing ability reaches a peak around age 20, then declines steadily.
It is also essential to understand which cognitive abilities are measured by each test and sub-test. [1] There are also free, searchable websites with compendia of tests and the constructs they measure. Below are a small sample of some of the best-known measures of cognitive abilities and brief descriptions of their content: Inductive reasoning ...
The Wechsler intelligence scales were originally developed from earlier intelligence scales by David Wechsler.David Wechsler, using the clinical and statistical skills he gained under Charles Spearman and as a World War I psychology examiner, crafted a series of intelligence tests.
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.
Intelligence is tested with IQ tests and others, although these have issues with accuracy and completeness. In such tests, patients may be asked a series of questions, or to perform tasks, with each measuring a cognitive skill, such as level of consciousness, memory, awareness, problem-solving, motor skills, analytical abilities, or other ...
It generates a Full Scale IQ (formerly known as an intelligence quotient or IQ score) that represents a child's general intellectual ability. It also provides five primary index scores, namely Verbal Comprehension Index, Visual Spatial Index, Fluid Reasoning Index, Working Memory Index, and Processing Speed Index.
