Phobias Flashcards
1
Q
Anxiety vs Fear
A
- Anxiety: general feeling of apprehension about possible future danger.
- Fear: alarm reaction that occurs in response to immediate danger.
2
Q
Anxiety disorders
A
- 25-29% of people in the US are affected.
- Most common category of disorders for women and second most for men.
- Creates enormous personal, economic and health problems.
- Associated with other medical conditions (asthma, chronic pain, hypertension, arthritis, cardiovascular, bowel syndrome etc)
3
Q
Fear response patterns
A
- Basic emotion that involves the activation of the fight or flight response of the autonomic nervous system.
- instantaneous reaction to any imminent threat.
Three components:
1. Cognitive/subjective components
2. Physiological component
3. Behavioral component
4
Q
Anxiety response patterns
A
- Complex blend of unpleasant emotions and recognitions that is both more oriented to the future and much more diffuse than fear.
- Also has the three components
- No activation of the fight or flight response, instead, it primes a person for the fight or flight response should the anticipated danger occur.
- In mild/moderate degrees it increases learning and performance but it can become maladaptive if severe.
5
Q
Specific phobias
A
- Strong persistent fear that is triggered by the presence of a specific object/situation.
Subtypes:
1. Animals
2. Natural environment
3. Blood-injection-injury
4. Situational
5. Others
6
Q
Specific phobias: prevalence, age, gender
A
- 12%
- 75% have at least one other specific excessive fear
- Gender ratio varies but usually more in women.
- Age: varies
7
Q
Psychological etiology (SP): psychoanalytic
A
- Defense against anxiety that stems from repressed impulses from the ID.
- Long criticized for being far too speculative.
8
Q
Psychological etiology (SP): learned behavior
A
- Wolpe and Rachman in 1960
- Development through classical conditioning.
9
Q
Psychological etiology (SP): vicarious conditioning
A
- Observing and modeling others.
10
Q
Psychological etiology (SP): differences in learning
A
- Life experiences may serve as risk factors, to protect or make them more vulnerable to phobias.
- Experiences before and after has an effect on the strength and maintenance of the phobia.
- Cognition or thoughts help maintain phobias.
11
Q
Psychological etiology (SP): evolution
A
- The way primates lived/live.
- Selective advantage
- Not inborn or innate but easily acquired or especially resistant to extinction.
12
Q
Genetic etiology (SP):
A
- Genetic + temperamental variables = speed and strength of conditioning of fear.
- Serotonin-transport gene (s allele) = superior fear conditioning
- MZ twins share animal + situational phobias more than DZ
13
Q
Treatment of Specific phobias: Exposure therapy
A
- Controlled exposure to stimuli/situations.
- Gradually placed - symbolically or increasingly - under ‘real life’ conditions.
- Long periods of time till fear subside.
14
Q
Treatment of Specific phobias: Modeling
A
- Models ways of interacting with phobic stimulus/situation.
- Mediated by changes in brain activation in the amygdala.
- Highly effective if treatment administered in a single long session (3hours).
15
Q
Treatment of Specific phobias: Virtual reality environments
A
- Virtual reality setting for certain phobias.
