intelligence test
a method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores
intelligence
mental quality consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations
general intelligence
a general intelligence factor that according to Spearman and others underlies specific mental abilities and is therefore measured by every task on an intelligence test.
factor analysis
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
savant syndrome
a condition in which a person otherwise limited in mental ability has an exceptional specific skill, such as in computation or drawing
emotional intelligence
the ability to perceive, understand, manage, and use emotions
mental age
a measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance. Thus, a child who does as well as the average 8-year-old is said to have a mental age of 8.
Stanford-Binet
the widely used American revision (by Terman at Stanford University) of Binet's original intelligence test
intelligence quotient
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.
achievement tests
a test designed to assess what a person has learned
aptitude tests
a test designed to predict a person's future performance; aptitude is the capacity to learn.
Wechsler Adult Intelligence Scale
the WAIS is the most widely used intelligence test; contains verbal and performance (nonverbal) subtests.
standardization
defining meaningful scores by comparison with the performance of a pretested standardization group
normal curve
the symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes. Most scores fall near the average, and fewer and fewer scores lie near the extremes.
reliability
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
validity
The extent to which a test measures or predicts what it is supposed to.
content validity
The extent to which a test samples the behavior that is of interest.
predictive validity
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.
Intellectual disability
(formerly referred to as mental retardation) 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
Down syndrome
a condition of retardation and associated physical disorders caused by an extra chromosome in one's genetic makeup
