Intelligence test
A method for assessing on individual’s mental attributes & comparing them with those of others, using numerical scores
Achievement test
A test designed to assess what a person has learned.
Aptitude test
A test designed to predict a person’s future performance; aptitude is the capacity to learn.
Collectivism & Individualism
C: family, community, society welfare
I: promoting individual opportunity
Frana’s Gatton
Mental Age
A measure of intelligence test performance devised by Binet; the level of performance typically associated with children of a certain chronological age.
Stanford-Binet
The widely used American revision of Binet’s original intelligence test.
Intelligence quotient (IQ)
A score from a standardized test that measures cognitive abilities like reasoning, problem-solving, & memory.
Ratio of mental age (ma) to chronologial age (ca) multiplied by 100.
On contemporary intelligence tests, the average performance for a given age is assigned a score of 100.
- Now, relative to the average performance
Wechsler Adult Intelligence Scale (WAIS)
A standardized IQ test developed by David Wechsler to measure intelligence and cognitive ability in adults and older adolescents.
It assesses various aspects of intelligence, including verbal and nonverbal abilities, through subtests that measure areas like verbal comprehension, perceptual reasoning, and working memory.
Psychometrics
The scientific study of the measurement of human abilities, attitudes, & traits.
Standardization
Defining uniform testing procedures & meaningful scores by comparison with the performance of a pretested group.
Normal curve
The bell-shaped curve that describes the distributions of many physical & psychological attributes.
Most scores fall near the average & fewer scores lie near the extremes.
Flynn effect
The rise in intelligence test performance over time & across cultures.
Reliability
The extent to which a test yields consistent results, as assessed by the consistency of scores on 2 halves of the test, on alternative forms of the test, or on retesting.
Validity
The extent to which a test measures or predicts what it is supposed to.
Content validity
How well a test samples all the relevant parts of the specific topic or “construct” (like memory or intelligence) it’s supposed to measure
Construct validity
How much a test measure a concept or trait.
Predictive validity
The success with which a test predicts the behavior it is designed to predict; it is assessed by computing the correlation between tests scores & the criterion behavior.
(Also called criterion-related validity.)
Cross-sectional study
Research that compares people of different ages at the same point in time.
Longitudinal study
Research that follows & retests the same people over time.
Heredity
The portion of variation among individuals in a group that we can attribute to genes.
Growth mindset
The belief that intelligence & abilities aren’t fixed but can be developed through dedication, hard work, & learning.
