CONCEPT QUESTIONS:
1.	How is Alfred Binet’s concept of “mental age” different from “chronological age”?  Why was this new concept helpful in evaluating school aged children?
2.	Differentiate Binet’s “mental age” from Stern & Terman’s “Intelligence Quotient” which is used in modern intelligence testing.  
3.	Describe the mathematical and conceptual changes made in current IQ testing (such as the WAIS).
4.	Assuming that intelligence scores are “normally distributed”, how does “spread of scores” across the population help us understand a single individual score (think percentile).
5.	What is meant by test reliability?  Why is it important that IQ test have very high reliability?
6.	What is meant by test validity? Give some good reasons that the relationship between IQ and performance (correlation) may be modest in predicting school grades, and even less predictive of vocational success.
7.	What does research tell us about whether intelligence is inherited?   (Use twin and adoption studies to support your answer!)
8.	What does research tell us about whether intelligence is environmentally influenced? 
9.	How does the concept of reaction range explain how heredity and environment may act together to affect IQ (or other traits, for that matter!)
10.	How does recent research on “socioeconomic disadvantage”  help to clarify the controversial debate on the question of what contributes to cultural variations in IQ scores?
11.	What is the interest in obtaining a biological measure of intelligence?
12.	How have Sternberg and Gardner attempted to expand our understanding of “Intelligence”.  What has each proposed?
