Q

3 Potential Explanations for the link of CAH to spatial skills

A
  1. Androgens could affect areas of the brain that are linked to spatial skills, masculine social behavior and sexual orientation
  2. Androgens could effect the tendency to engage in activities that affect cognition and behavior
  3. The masculinization of appearance could somehow influence behavior

Q

Two ways of examining the effect of hormones on cognitive and behavior?

A

Examining the different levels of hormones across women and men to behavior

49
Q

Q

Q

Why does CAIS occur?
