chemicals produced by the endocrine glands

21
Q

what are the strengths of the biological approach

A

-one of the most scientific approaches
-has useful applications

22
Q

what are the useful applications of the biological approach

A

biological treatment (e.g surgery or drug treatment)

23
Q

what are the limitations of the biological approach

A

-deterministic (ignores free will)
-socially sensitive
