according to Spearman and others, underlies specific mental abilities and is therefore measured by every task on an intelligence test
general intelligence (g)
a statistical procedure that identifies clusters of unrelated items (called factors) on a test; used to identify different dimensions of performance that underlie a person’s total score
factor analysis
a condition in which a person otherwise limited in mental ability demonstrates profound and prodigious capacities and/or abilities dar in excess of what would be considered normal
savant syndrome
in psychology, a passion and perseverance in the pursuit of long-term goals
grit
the ability to perceive, understand, manage, and use emotion
emotional intelligence
a measure of intelligence test performance devised by Binet; the chronological age that most typically corresponds to a given level of performance.
mental age
the widely used American revision (by Teraman At Stanford University) of Binet’s original intelligence test
Stanford-Binet
defined originally as the ratio of mental age (ma) to chronological age (ca) multiplied by 100 (IQ = [ma/ca]*100). on contemporary intelligence tests, the average performance for a given age is assigned a score of 100, with scores assigned to relative performance above or below average.
intelligence quotient (IQ)
mental quality consisting of the ability to learn from experience, solve problems, and sue knowledge to adapt to new situations
intelligence
british statistician and psychologist. coined the term factor analysis. two-factor theory. theorized that all behaviors we considered to be intelligent have a common underlying factor, “g”, which stands for general intelligence. “s” = specific mental ability
Charles Spearman/Spearman’s Two-Factor Theory
created the first practical intelligence test, used to measure mental age
Alfred Binet
a test designed to assess what a person has learned
achievement test
a test designed to predict a person’s future performance; aptitude is the capacity to learn
aptitude test
the WAIS is the most widely used intelligence test; contains verbal and performance (nonverbal) subtests
Wechsler Adult Intelligence Scale (WAIS)
defining uniform testing procedures and meaningful scores by comparison with the performance of a pretested group
standardization
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
normal curve
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
reliability
the extent to which a test measures or predicts what it is supposed to
validity
the extent to which a test samples the behavior that is of interest
content 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)
predictive validity
American psychologist Louis Thurstone believed that 7 separate factors, or “primary mental abilities”, make up intelligence.
–verbal comprehension, word fluency, number facility, spatial visualization, association memory, perceptual speed, reasoning
Thurstone’s Theory of Primary Mental Abilities
contemporary american psychologist Howard Gardner theorized that intelligence has a broader base and that multiple kinds of intelligence exists within us.believes that the different intelligences are independent of each other
– linguistic, logical-mathematic, visual-spatial, bodily-kinesthetic, musical-rhythmic, interpersonal, intrapersonal, naturalist, spiritualist.
Gardner’s Theory of Multiple Intelligence
american psychologist Robert Sternberg believes that different kinds of intelligences all work together, created a 3-level model of intelligence.
–analytic, ability to solve problems. creative, ability to deal with new situations. practical, ability to accomplish everyday tasks.
Sternberg’s Triarchic Theory
in the past 60 years, intelligence scores have risen steadily by an average of 27 points.
