Biological Paradigm

Mental Disorders are caused by some somatic process or defect: "Medical Model"

• Genetics, Chemical Imbalances, Neuroanatomical abnormalities.

Psychoanalytic Paradigm

Classical Conditioning

Unconditioned Stimulus/Response Conditioned Stimulus/Response

Classical Conditioning Example

Little AlbertLoud Noise (UCS) -> Fear (UCR)White Rat(CS)-> Fear (CR)

operant conditioning

Purpose of Clinical Assessment
