Biological Theory

Phobia does not seem to be inheritable but there are heritable components to anxiety disorders

Biochemical treatments

phobia needs to have learned component
GABA definency?
GABA- NT that comes back down from anxiety
Alcohol= GABA agonists- decrease anxiety

Benzodiazepines (Xanax, Valium)

drugs that lower anxiety and reduce stress
Faciliate action of GABA in brain
Elusive findings-- dimished GABA in brain of Phobic
severe withdraw- rebound anxiety
Very short term- less than 2 weeks

MAO inhibitors (MAOIs)- Marplan Nardil

helps social phobia
bad side effects
inhibit reuptake of monoamines

SSRIs (Paxil, Prozac, Zoloft)

help social phobia
facilitate action of serotonin
no current evidence for serotonin deficiency
60% improve

5-HT 1A agonist (Buspar)

Social specific
serotonin receptor agonists
best as adjunctive treatment for other meds
---helps how well they respond, not if they do

Beta Blockers (propanol)

heart medication
control heart rate/bp
stop other symptoms?
little effiencey data
nurephineren antagonists---block receptor

psychodynamic theory and treament

poorly designed oedipus complex
--displaced fear onto other object
castration anxiety displaced onto innocent object
--Little Hans
fear of horses
5 yr old phalic stage
horse became hanger to fit fear for dad like features

Psychodynamic treatment and research

treatment
-- standard psychoanalysis
research
--poor outcomes
30-40% got better--30-40% placebo
cant accept underlying reason?

Behavioral theory

development of phobia
-direct exposure to phenomenon
-panic attack in specific situation
-observational/ informational
--hearing/seeing someone else have phobia
learned component
PHOBIAS CLASSICALLY CONDITIONED- MAINTAINED BY AVOIDANCE OF PHOBIC OBJECT OR SITUATION
--little albert--lack of exposure- extinction- need to be in presence of cs

Mowrer's two-factor model

Pairing of stimulus with aversive UCS leads to fear (Classical Conditioning)
Avoidance maintained though negative reinforcement (Operant Conditioning)

behavioral treatment

exposure
-systematic desensitization
---cant be relaxed and tense at the same time

counter-conditioning/systematic desensitization

- type of behavioral therapy based on the principle of classical conditioning
-aims to remove the fear response of a phobia and substitute a relaxation response to the conditioned stimulus gradually using counter conditioning
-There are three phases to the treatment
-The client repeatedly imagines (or is confronted by) this situation until it fails to evoke any anxiety at all, indicating that the therapy has been successful. This process is repeated while working through all of the situations in the anxiety hierarchy until the most anxiety-provoking
-build up in intensity
-progressive relaxation with exposure
-if anxiety felt- start over

graduated exposure

in behavior therapy, a method in which a person suffering from a phobia or panic attacks is gradually taken into the feared situation or exposed to a traumatic memory until the anxiety subsides
-no relaxation
