EDST 391 Intelligence in Everyday Life


P/F Writing Assignment for Day 17

Brain correlates of g


1. To what extent does IQ correlate with brain attributes such as size, glucose uptake, speed of neural transmission, and AEP latency and amplitude? (Briefly summarize the most important findings.). Do these correlations prove that differences in intelligence are to some extent genetic rather than strictly environmental in origin? (Please explain.)

2. Turning to a different question, In what ways do these data constrain our theorizing about why people turn out to be so different in intelligence? (Think like a detective who has discovered some clues.) For example, do they rule out certain explanations (suspects) or make others more likely?

3. Are the brain-IQ correlations "bad news" if your goal is to improve intelligence? Why or why not? Think beyond the obvious.
