CRR: The RAIT is an
intelligence test designed for group or individual administration via paper and pencil booklets or online.
But all of these genes together account for just a small percentage of the variation in
intelligence test scores, the researchers found; each variant raises or lowers IQ by only a small fraction of a point.
It is because of this case, along with subsequent rulings by the California Department of Education, that Larry along with all African-American students in the state of California cannot have their
intelligence tested by standardized intelligent tests.
These results suggest examinees evaluated by examiners who are provided deliberate test practice and have more experience with the administration and scoring of an
intelligence test will tend to obtain higher scores than examinees evaluated by examiners who have less experience and deliberate practice with test administration.
Intelligence test measure an individual's ability in relatively global areas such as verbal comprehension, perceptual organization, or reasoning and thereby help determine potential for scholastic work or certain occupation (Gregory,2006,P:58).E.L.Thorndike divided intelligent activity into three types: social intelligence, or ability to understand and deal with person; concrete intelligence or ability to understand and deal with things and abstract intelligence, or ability to understand and deal with verbal and mathematical symbols (Freeman, 1963, p: 157).
Culture Fair
Intelligence Test. As a test with low demands on fine motor skills, the pupils worked through the German version (Weiss, 2006) of the Culture Fair
Intelligence Test (CFT20; Cattell, 1960).
Other researchers have viewed
intelligence test scores as possibly more than just an indicator of an efficient brain.
Measuring minds is a rich and informative biography of Henry Herbert Goddard, the man credited with being the first American to realize the potential and applicability of the Binet
intelligence tests and help their dissemination throughout America's institutions.
And Charles Murray, then as now an AEI fellow, wrote 1995's The Bell Curve, which argued that
intelligence test score differences among the races were in part genetically determined.
But it was not simply socializing and talking that fertilized children's intellect, it was being in what Vygotsky called the "zone of proximal development." Like Piaget, Vygotsky was not intrigued by children's intellectual level, as measured by an
intelligence test. But unlike Piaget -- who focused on how children made mistakes -- Vygotsky focused on what children could accomplish with the assistance of another person.
What must be remembered is that behavior genetic research can only estimate to what extent the variance of one measurement, such as
intelligence test scores, is correlated with the variance of another measurement, such as genetic differences, in a population of individuals.
The committee developed a prototype of the Army alpha examination, a group-administered paper-and-pencil test given to wartime recruits, which was the first large-scale administration of an
intelligence test and a landmark in the development of standardized testing.
