No assessment Testament bid you 100 percent if you're a brainiac or not, however some can be commendable indicators.
Fundamental introduced by the French psychologist Alfred Binet, IQ --- or "Intelligence Quotient" --- was originally conceptualized for diagnosing intellectual retardation in children. A ratio of a babe's intellectual time against his chronological day, "ratio IQ" was next deemed inappropriate for measuring intelligence in adults.
From "Ratio IQ" to "Deviation IQ"
Scores on virgin tests are no longer quotients or ratio IQs, on the other hand rather "deviation" IQs. Inured equivalent percentile ranks --- such that a class of 99 percentile places one in the top 1 percent of his interval bevy, 95 percentile in the top 5 percent, and so on --- deviation IQ measures the deviation of a mortal's intelligence from the guideline intelligence of others of the duplicate time. With the duration "IQ" growth technically inaccurate, the period "intelligence crack" is another commonly used.
Standardized and Norm Referenced Tests
Further called "potential-based assessments," intelligence tests predict an distinct's mental or academic performance with hovering degrees of confidence. Provisioned for controlling the elements of the testing manner, most intelligence tests are standardized. Characterized by stringent inspection criteria, standardized tests retain fix procedures governing research government, interrogation wording and acceptability of answers.
"Norm-referenced" tests place the domination of many factors ---such as culture--- on countdown performance. "Norming" a catechism involves a prior state of the test to large numbers of subjects for whom the test is designed. Individual scores in a norm-referenced test are compared against group performance --- thus, norm-referenced tests determine how well one performs compared to people of his age and of the same culture.
Common Intelligence Tests for Children
The first intelligence tests were designed for children, most widely-used of which is the Stanford-Binet Intelligence Scales, which had undergone as many as five editions. Other widely-used intelligence tests for children include the Cognitive Assessment System (CAS), the Kaufman Assessment Battery for Children (KABC) and the Wechsler Intelligence Scale for Children (WISC).
Intelligence Tests for Adults
Called the Wechsler Adult Intelligence Scale (WAIS), this first and most widely-used intelligence test for adults was designed by David Wechsler during the 1930s.Some standardized tests tend to discriminate against children with verbal expression difficulties, whether due to physical impairment, language difficulty or lack of confidence. Designed to offset these disadvantages, non-verbal tests involve as little verbal expression as possible or none at all. Some of the most widely used non-verbal intelligence tests are the Comprehensive Test of Nonverbal Intelligence (CTONI), the Universal Nonverbal Intelligence Test (UNIT) and Raven's Progressive Matrices.
A version for children followed soon after. The latest edition of the Stanford-Binet Intelligence Scales (SBIS-V) covers older age ranges also.
