Term
intelligence
Definition
ability to acquire knowledge, to think and reason effectively, and to deal adaptively with the environment
Term
Sir Francis Galton
Definition
studied fingerprinting, meteorology, use of prayer to control weather, family trees, hereditary genius

believed that some people had "inherited mental constitutions"

created his own measures of mental abilities
Term
Alfred Binet
Definition
commissioned to develop a procedure for identifying "special needs" children

his test emphasized verbal content, rather than the sensory and perceptual skills favored by Galton

introduced concept of "mental age"
Term
Stanford-Binet
Definition
Binet's test, revised and translated by Lewis Terman of Stanford University
Term
ratio IQ
Definition
(mental age/chronological age) x 100

100 is regarded as average
Term
deviation IQ
Definition
expresses the individual's test performance in relation to an appropriate comparison group

100 is regarded as average

WAIS, WISC, WPPSI

include verbal and non-verbal material

individual differences in perceptual and cognitive processing of test items

borrows heavily from laboratory research on memory
Term
primary methodology
Definition
statistical analysis of correlations between...
Term
psychometric approach
Definition
Six tests: vocabulary, analogies, synonyms, long devision, fractions, square roots

shaded areas represent two clusters (factors) of intelligence tests; all test correlations are positive and substantial in size
Term
general intelligence (g)
Definition
influences performance on all mental ability tasks
Term
specific abilities (s)
Definition
influences performance on specific tasks
Term
crystalized intelligence
Definition
Cattell and Horn; information you know; continues to increase through adulthood

Performance subtests: picture completion, digit symbol-coding, block design, matrix reasoning, picture arrangement, symbol search, object assembly
Term
Army Alpha/Beta test
Definition
group test
not used to diagnoses, but for placement

alpha: for literate people
beta: for illiterate or foreign people
Term
SAT, ACT, GRE

Term
variability
Definition
range, standard deviation
Term
standard scores
Definition
ex. z, IQ

z = (x-mean)/SD
Term
correlation coefficient
Definition
r

-1 to +1

+1 means perfect association between two variables
-1 means a perfect negative correlation
Term
reliability
Definition
psychometric standards

reproducibility or consistency of scores
Term
validity
Definition
appropriateness of inferences from scores
Term

Definition
administration, scoring, interpretation
Term
r = .60
