Intelligence

mental quality consisting of the ability to learn from experience, solve problems, and use knowledge to adapt to new situations

intelligence test

a method for assessing an individual's mental aptitudes and comparing them with those of others, using numerical scores

general intelligence

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 on a test; used to identify 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

grit

passion and perseverance in the pursuit of long-term goals

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

Stanford-Binet

intelligence-quotient

defined originally as the ratio of mental age to chronological age multiplied by 100

achievement test

a test designed to assess what a person has learned

aptitude test

a test designed to predict a person's future performance

Weschler Adult Intelligence Scale (WAIS)

most widely used intelligence test; contains verbal and performance subtests

standardization

defining uniform testing procedures and meaningful scores by comparison with the performance of a pretested group

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

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.

cohort

a group of people from a given time period

crystallized intelligence

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

fluid intelligence

our ability to reason speedily and abstractly; tends to decrease during late adulthood

intelligence disability

a condition of limited mental ability, indicated by an intelligence score of 70 or below and difficulty in adapting to the demands of life

Down Syndrome

a condition of intellectual disability and associated physical disorders caused by an extra copy of chromosome 21.

heritability

The proportion of variation among individuals that we can attribute to genes, may vary depending on the range of populations and environments studied.

stereotype threat

a self-confirming concern that one will be evaluated based on a negative stereotype
