Midterm #2 (intelligence) Flashcards
Who were Alfred Binet and Theodore Simon?
First people to develop an intelligence test. They were asked by the French government to make a test to find out which children were mentally weak.
Who was William Stern?
The first person to give a quantifiable measure of intelligence (IQ).
What is ratio IQ? Is it a good measure of intelligence?
Ratio IQ = 100 x mental age/chronological age. Not a good measure of intelligence because intelligence eventually eves out as we age.
What is deviation IQ? Is it a good measure of intelligence?
Deviation IQ = 100 x (your test score/average test score of others your age). Is a better measure of intelligence.
