UNIT 5 LESSON 5 Flashcards
Intelligence Tests
Created the first intelligence test
Francis Galton
a movement bent on improving the human gene pool
eugenics movement
the average performance of people at a certain age
mental age
openly criticized Spearman’s factor analysis method, devising a far more effective and accurate psychometric technique
Louis Leon Thurstone
devised the Stanford-Binet intelligence quotient (IQ)
test.
Lewis Terman
asserts that once states are stable, provide education, and are also affluent enough to afford ample nutrition to children, teens, and adults for proper brain development, one’s genetic potential for intelligence may be realized.
Flynn Effect
asserted that Spearman’s g factor was too narrow, and, furthermore, that intelligence was more an effect than a cause. Therefore, he developed the WAIS.
David Wechsler
tests that predict a person’s future performance and capacity to learn.
aptitude tests
results must be compared to a presented group or population
standardized
a relative ranking out of 100 according to the values of a particular variable
percentile
meaning scores of half of test, a new test, or retests or the same test, must have the same or similar results within a given population
reliable
meaning a test must accurately measure what it is supposed to
valid
the diminishing ability of tests to measure future learning
predictive validity
two examples are rearranging blocks into images in the WAIS and how psychologists such as Sternberg attempted to measure creativity by having
participants caption an image
abstract measures
an example is a participant is asked to find similarities in
words, as well as describe and explain solutions & problems verbally rather than through reading or writing on paper
Verbal measures
