Understanding how psychology is changed over time

• areas of the brain ( brain damage )

• brain laterlisation (sperry sex differences ligh/right hemisphere
  -Prosopagnosia

Question 2

EEG

Answer 2

• a way to measure brain wave activity in living brain
• start of ways to study the brain that didn’t rely on the patient being dead or unconscious

• possible to investigate behaviour level of the neuron
• using this evidence has been able to show that people with risk-taking and impulsive behavions often have high levels of dopamine in their nervous system
