Intelligence and Achievement Assesing Intelligence
Intelligence Test
A method for assessing an indivdual’s mental aptitudes and 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.
Mental Age
A measure of intelligence test performance devised by Binet; the level of performance typically associated with children of a certain chronologicala ge. Thus, a child who does as well as an average 8 year old is said to have a mental age of 8.
Stanford-Binet
The widely used American revision of Binet’s original intelligence test.
Intelligence Quotient (IQ)
Defined originally as the ratio of mental age to chronomigical age multipled by 100. (IQ=ma/ca x 100).
Wechsler Adult Intelligence Scale (WAIS)
The WAIS and its companion versions for children are the most widely used intelligence tests; they contain verbal and [erformance (nonverbal) subtests.
Psychometrics
The scientific study of the meausrement of human abilities, attitudes, and traits.
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.
Flynn Effect
The rise in intelligence test performance over time and across cultures.
Reliability
The extent to which a test yiels consistwnt results, as assessed by the consistency of scores on two halves of the test, on alternating 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.
Construct Validity
How much a test measures 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 test scores and the criterion behavior.
