Question 2

Examining the relationship between two variables (measures association)

Answer 2

correlation

Question 3

Manipulating the experience/behavior, measure effects on the brain and causality

Answer 3

Behavioral Manipulation

Question 4

Manipulating the brain/body, measures the effect on behavior and causality

Answer 4

Somatic (body) manipulation

Question 5

Generates ‘static’ high resolution images of tissue and indexes distribution/chemistry of hydrogen protons and neutrons

Answer 5

structural MRI
