Classifying Psychological Disorders
The American Psychiatric Association uses a Diagnostic and Statistical Manual of Mental Disorders (DSM) to describe
psychological disorders.
The most recent edition, DSM-IV-TR (Text Revision, 2000), describes 400
psychological disorders compared to 60 in the 1950s.

Goals of DSM
1. Describe (400) disorders.2. Determine how prevalent the
disorder is.
Disorders outlined by DSM-IV are reliable. Therefore, diagnoses by different professionals are similar.
Others criticize DSM-IV for “putting any kind of behavior within the compass of psychiatry.”

Resilience to PTSD
Only about 10% of women and 20% of men react to traumatic situations and
develop PTSD.
Holocaust survivors show remarkable resilience against traumatic situations.
All major religions of the world suggest that surviving a trauma leads to the
growth of an individual.

Explaining Anxiety Disorders
Freud suggested that we repress our painful and intolerable ideas, feelings,
and thoughts, resulting in anxiety.

The Learning Perspective
Learning theorists suggest that fear
conditioning leads to anxiety. This
anxiety then becomes associated with other objects or events (stimulus generalization) and
is reinforced.

21
The Learning Perspective
Investigators believe that fear responses are inculcated through observational learning. Young monkeys develop fear
when they watch other monkeys who are afraid of snakes.

22
The Biological Perspective
Natural Selection has led our ancestors to learn to fear snakes, spiders, and other animals. Therefore, fear preserves the
species.
Twin studies suggest that our genes may be partly responsible for developing fears
and anxiety. Twins are more likely to share phobias.

The Biological Perspective
Generalized anxiety, panic attacks, and
even OCD are linked with brain circuits like the
anterior cingulate cortex.
GABA plays a key role

DID Critics
Critics argue that the diagnosis of DID increased in the late 20th
century. DID has not been found in other countries.
Critics’ Arguments
1. Role-playing by people open to a therapist’s suggestion.
2. Learned response that reinforces reductions in anxiety.
