Psych ch. 11&15 Flashcards
intelligence test
a method for assess- ing 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 (g)
a general intelligence factor that, according to Spearman and others, underlies specific mental abilities and is therefore mea- sured 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 identi- fy different dimensions of performance that underlie a person’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.
creativity
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 perfor- mance. 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 (IQ)
defined originally as the ratio of mental age
(ma) to chronological age (ca) multi- plied 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 pre- dict a person’s future performance; apti- tude 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.
standardization
defining meaningful scores by comparison with the perfor- mance of a pretested group.
normal curve
the symmetrical bell- shaped curve that describes the distrib- ution of many physical and psychologi- cal 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, or on retesting.
validity
the extent to which a test measures or predicts what it is sup- posed 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.
mental retardation
a condition of limited mental ability, indicated by an intelli- gence score of 70 or below and difficul- ty 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.
personality
an individual’s characteristic pattern of thinking, feeling, and acting.
free association
a method of exploring the unconscious in which the person relaxes and says what- ever comes to mind, no matter how triv- ial or embarrassing.
psychoanalysis
Freud’s theory of per- sonality that attributes thoughts and actions to unconscious motives and con- flicts; the techniques used in treating psychological disorders by seeking to expose and interpret unconscious tensions.
