The Intellect


1. The origins of intelligence testing.

a. Alfred Binet Predicting school achievement

b. Lewis Terman the inborn intelligence

c. William Stern the INTELLIGENCE QUOTIENT (IQ).


2. What exactly do intelligence tests measure: One general intelligence or multiple intelligences (e.g. social, emotional, etc.)?
 


CONCLUSION 1:


It seems that academic aptitude is to a large degree predicted by general intelligence tests (remember these tests were designed to predict achievement in school).  However, personal competence in everyday life requires many more skills that traditional intelligence tests cannot measure.


3. Genetic and environmental influences on individual differences in intelligence twin and adoption studies; correlation between sibling IQ scores
 


CONCLUSION 2:

Both heredity and environmental factors interact to influence mental abilities.
