Development of Anxiety
- Anxiety is linked to classical conditioning
- Fear Conditioning- anxiety is the classical conditioning of fear
- Stimulus Generalization
- Observational Learning- people learn to fear the same thing that other people fear
Genes: Pair a traumatic event with a sensitive, high-strung temperament and the result may be a new phobia. Vulnerability to anxiety disorder rises when the afflicted relative is an identical twin.
The brain: Generalized anxiety, panic attacks, and even obsessions and compulsions are biologically measurable as an over arousal of brain areas involved in impulse control and habitual behaviors. Fear-learning experiences can traumatize the brain, by creating fear circuits within the amygdala. Some antidepressant drugs dampen this fear-circuit activity and its associated obsessive-compulsive behavior.
- Memory loss (amnesia) of certain time periods, events and people
