intelligence test
a method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores.
mental quality consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations.
general intelligence (g)
a general intelligence factor that, according to Spearman and others, underlies specific metal 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.
the ability to produce novel and valuable ideas.
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.
the widely used American revision (by Lewis Terman at Stanford University) of Binet's original intelligence test.
intelligence quotient (IQ)
defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 [thus, IQ = (ma/ca) x 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 (WAIS)
the WAIS is the most widely used intelligence test; contains verbal and performance (nonverbal) subtests.
defining meaningful scores by comparison with the performance of a pretested group.
normal curve
the symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes, including intelligence. Most scores fall near the average, and fewer and fewer scores lie near the extremes. 1 Standard Deviation=15
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 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. (Also called criterion-related validity.)
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 copy of chromosome 21.
stereotype threat
a self-confirming concern that one will be evaluated based on a negative stereotype.
Alfred Binet
Developed the Binet Simon test, which sought to measure children's mental age and help French schoolchildren get needed attention.
Howard Gardner
Views intelligence as multiple abilities. Proposed 8 multiple intelligences: Naturalist, Linguistic, Logical-mathematical, Musical, Spatial, Body-kinesthetic, Intrapersonal, and Interpersonal.
Supported by savant syndrome.
Charles Spearman
Believed we have a g- general intelligence. Found clusters of related items and developed factor analysis, which identifies common dimensions of performance.
William Stern
Devised the Inteligence Quotient:
(mental age/chronological age)x100
Robert Sternberg
Agreed with gardner that there are multiple intelligences, bur proposed a Triarchic Theory: 3 intelligences- Analytic problem solving, Creative and Practical Intelligence.
Lewis Terman
Modified the Binet Simon test to be suitable for Americans, devised the Stanford-Binet test, which was supported Eugenics during WWI and in immigration Quotas.
LL Thurstone
Spearman's early opponent, was initially against a single intelligence scoring system. Devised 7 Clusters of mental ability: Word fluency, Verbal comprehension, Spatial Ability, Perceptual speed, Numerical ability, Inductive reasoning and Memory.
David Wechsler
Created the most widely used intelligence test: the WAIS for adults and the WISC for children. Yields an overall score, but separates scores into subfields also.
