a method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores., a method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores
a measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance
defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 (thus, IQ = ma/ca × 100). On contemporary intelligence tests, the average performance for a given age is assigned a score of 100.
a test designed to predict a persons future performance; aptitude is capacity to learn
Wechsler Adult Intelligence Scale
the most widely used intelligence test; contains verbal and performance (nonverbal) subtests.
defining meaningful scores by comparison with the performance of a pretested standardization group
the symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes
the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting.
the extent to which a test samples the behavior that is of interest (such as a driving test that samples driving tasks).
a self-confirming concern that one will be evaluated based on a negative stereotype.
The success with which a test predicts the behavior it is designed to predict; it is assessed by computing the correlation between test scores and the criterion behavior.
mental quality consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations
a statistical procedure that identifies clusters of related items (called factors) on a test; used to identify different dimensions of performance that underlie one's total score
General Intelligence (g)
a general intelligence factor that Spearman and others believed underlies specific mental abilities and is therefore measured by every task on an intelligence test
a condition in which a person otherwise limited in mental ability has an exceptional specific skill, such as in computation or drawing.
a condition of limited mental ability, indicated by an intelligence score of 70 or below and difficulty in adapting to the demands of life; varies from mild to profound
a condition of retardation and associated physical disorders caused by an extra chromosome in one's genetic makeup
