What's Agorophobia?
Fear of going outside. Panic disorders can lead to agoraphobia, but it is much more common to have a panic disorder without agorophobia
Etiology of Phobias
Mowrer's Two-Factor Model: The fear component of phobias is believed to be acquired through classical conditioning. The avoidance behavior is acquired and maintained by operant conditioning, specifically negative reinforcement (relief from anxiety negatively reinforces the avoidance of fearful stimuli). Observational Learning: May acquire phobia by watching others around you having fearful reactions Biological: May have overactive amygdala, inducing a fear response. The prefrontal cortex give the "All Clear" signal, this discovery could lead to new treatment.
