Abnormal Behavior and Therapy:
Defining Abnormality
What is a mental disorder?
A variety of cognitive, emotional, and behavioral symptoms that:
Deviate from the norm
culturally-determined
EX: someone has died, and you feel that you talk/see them sometimes. Is
this person hallucinating, or is this culturally normal for them to report
seeing, hearing the dead.
OR… the APA’s (american psychiatric association) definition
Distress: bother the individual to feel this way
Disability: negatively affects your ability to function every day
Danger: depression, thoughts of suicide,
EX: imagine you see a man raising his hands to the sky, shaking his fists and shouting. He
claims that beings from outer space speak to him and that he can talk to them.
Culturally:
walking into church this is common
EX: a person you know begins crying excessively, withdraws socially, and is not acting like
him/herself at all. For two weeks, this person does not leave the house except to go to work and
stops talking to friends
Culturally:
A death of a loved one
EX: imagine you see a person in the grocery store. In the middle of the aisle, this child drops his
pants, takes off his shirt, and begins running around laughing hysterically
Culturally:
normal, young child being silly
It’s all about CONTEXT
“Individuals with mental disorders are different than others in degree, not in kind”
EX: Depression: people are sad and moody for very long periods of time….. But an
average person still feels the same feelings as depression. Depressed people have the
same feelings as a normal person, just have a more extreme version of it.

depressed
