Francis Galton

gave statistical techniques that we still use, although his quest for a simple intelligence measure failed

Alfred Binet

general IQ tests, designed test to identify slow learners in need of remediation-not applicable in the U.S. because too culture-bound (French)

Carol Dweck

growth mindset; thought that the need for achievement is closely linked to personality facts, including view of self; suggested students with long history of success are at most risk for learned helplessness after big failure of their own intelligence

grit

in psychology, grit is passion and perseverance in the pursuit of long-term goals

fluid intelligence

our ability to reason speedily and abstractly; tends to decrease with age, especially during late adulthood

crystallized intelligence

our accumulated knowledge and verbal skills; tends to increase with age

cross-sectional study

research that compares people of different ages at the same point in time

longitudinal study

research that follows and retests the same people over time

Lewis Terman

revised Binet's IQ test and established norms for American children; tested group of young geniuses and followed in a longitudinal study that lasted beyond his own lifetime to show that high IQ does not necessarily lead to wonderful things in life

Wechsler Adult Intelligence Scale (WAIS)

the WAIS and its companion versions for children are the most widely used intelligence tests; they contain verbal and performance (nonverbal) subtests

intelligence

the ability to learn from experience, solve problems, and use knowledge to adapt to new situations

emotional intelligence

the ability to perceive, understand, manage, and use emotions

normal curve

the 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

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

reliability

the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternative forms of the test, or on retesting

heritability

the proportion of variation among individuals in a group that we can attribute to genes; the heritability of a trait may vary, depending on the range of populations and environments studied

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

Stanford-Binet

the widely used American revision (by Terman at Stanford University) of Binet's original intelligence test
