Types of Tests
Crystallized Intelligence
using knowledge accululated over time and holds steady or may increase ex. 60 year old has advantage on vocab test or an exercise dependent upon wisdom
Relationship between aptitude and achievement tests
they are interrelated 1.Whatever ones aptitude is for a specific skill, ones experience effects it(better schooling in math vs someone with no formal training in math) 2. ones who have achieved equally in learning biology will not necessarily score the same on an achievement test.
David Weshler
Weshler Adult Intelligence Scale 11 subtests yields deviation IQ
Fluid intelligence
ability to solve abstract problems and pick up new information ex 20 year old learning new computer language
Group tests
administered to large group of people at a time minimal interaction less money
Within group differences are typically larger than
between group differences
What are biological correlations to intelligence
brain size and neurological speed(Processing speed) and
Environment factors such as better nutrition, education have influence what effect
Flynn Effect
Alfred Binet
Frenchman designed a test that would identify what children needed special attention in school - came up with mental age that presupposes that intelligence increases as one gets older/
Louis Terman
Stanford Binet Test developed IQ 100 is average different kinds of questions on test
Speed tests determine
problem solving speed
power tests gauge
difficulty level of problems an individual can solve more time allotted to work out problem
Individual tests
greater interaction between examiner and examinee ( IQ tests
Heritability
measure of how much of a trait's variation is explained by genetic factors - Identical Twins share 100 % of genetic material , score ver similarily Fraternal Twins do not and therefore a lower correlation between identical and fraternal twins contributes to heritability factor
achievement tests
measure what one has already learned or accomplished ex. a subject test in school
aptitude tests
predicts and measure future ability or potential intelligence tests(IQ measure mental aptitude) or college entry exam
