Causes of Anxiety Disorders
 Biological
Factors
◦ Genetics have been found to be
a cause of panic disorders,
generalized anxiety disorder,
OCD, and phobic disorders
Causes of Anxiety Disorders
 Biological
Factors
◦ Biochemical changes in brain trigger
an “internal alarm” to induce panic
◦ Obsessional thinking may be linked
to danger sensing areas of the brain
may be heightened in some people.
Causes of Anxiety Disorders
 Psychological
Factors
◦ Phobias may be learned through classical
conditioning (people who have been bit
by dogs maybe scared of them).
◦ Operant conditioning may reinforce
avoidance behavior (avoidance of object
is negatively reinforced by feelings of
safety).
Causes of Anxiety Disorders
 Negative
reinforcement can help
perpetuate OCD (obsessive
thoughts trigger anxiety, which is
partially relieved through
performing a ritual. In effect, the
solution becomes the problem)
