Specific phobia

Question 1

Stress

Answer 1

Question 2

Anxiety

Answer 2

Unpleasant feelings of apprehension or uneasiness that something is wrong or something bad is about to happen.

Question 3

Phobia

Answer 3

Excessive, persistent and unreasonable fear of an object or situation.

Question 4

How are stress and anxiety different to a phobia?

Answer 4

• Can contribute to or develop into a mental health disorder, whereas a specific phobia is a diagnosed mental health disorder.

Question 5

How are anxiety and phobia different to stress?

Answer 5

They are distress only, whereas stress can be either eustress or distress.

Question 6

How are phobia and stress different to anxiety?

Answer 6

The source is usually known, whereas the source of anxiety may be unknown.

Question 7

Specific phobia

Answer 7

An anxiety disorder characterised by fear about a specific object or situation, often leading to avoidance behaviour.

Question 8

Social anxiety disorder

Answer 8

Excessive, persistent and unreasonable fear of social and performance situations, primarily due to concern about being negatively judged by others or behaving in a way that is embarrassing or humiliating.

Question 9

Agoraphobia

Answer 9

Characterised by fear and avoidance of places and situations that might cause feelings of panic, entrapment and embarrassment.

Question 10

Biological factors contributing to the development of a specific phobia

Answer 10

• GABA dysfunction
• Role of stress response
• Long-term potentiation

Question 11

GABA dysfunction

Answer 11

May cause an individual’s sympathetic NS to be activated more easily, meaning their stress response is more easily triggered by certain stimuli. Recurrent stress can lead to development of phobia.

Question 12

Long-term potentiation

Answer 12

Long-term potentiation can neurologically strengthen the association between a phobic stimulus and a fear response.

The more they are coactivated, the more the connection is strengthened. This enhances the transmission of transferring information and therefore decreasing the chances of forgetting the fear response.

Question 13

Psychological factors contributing to the development of a specific phobia

Answer 13

• Precipitation by classical conditioning
• Perpetuation by operant conditioning
• Cognitive bias (memory bias and catastrophic thinking)

Question 14

Precipitation by classical conditioning

Answer 14

When the NS becomes associated with the UCS (phobic stimulus), it becomes the CS, therefore eliciting the CR, increases the susceptibility of an individual to develop a phobia. By associating something with fear, the individual will then fear it.

Question 15

Perpetuation by operant conditioning

Answer 15

Any avoidance response (negative reinforcement) to any phobic stimulus will continue to be reinforced through operant conditioning. Avoidance reduces the unpleasant feelings of anxiety, so avoidance is negatively reinforced as it reinforces the fear.

Question 16

Cognitive bias (memory bias and catastrophic thinking)

Answer 16

Memory bias - Causes an individual to place emphasis on the negative experiences in a situation while disregarding the positive or neutral experiences.

Catastrophic thinking - an object or situation being perceived as far more threatening or dangerous than it really is. This can maintain the fear or anxiety response, perpetuating the phobia.

Question 17

Social factors contributing to the development of a specific phobia

Answer 17

• Specific environmental triggers
• Stigma

Question 18

Specific environmental triggers

Answer 18

Developing a specific phobia after a direct negative experience with an object or situation. The specific environmental trigger may induce a response from an individual when confronted.

Question 19

Stigma

Answer 19

Can prevent individuals from seeking treatment due to worrying about being judged. This can make it difficult for them to combat or overcome a phobia.

Question 20

Biological interventions that treat specific phobias
- explain each

Answer 20

Agonist
- Drug that imitates neurotransmitters and works to initiate a neural response (excitatory or inhibitory)

Benzodiazepines
- Short-acting anxiety medication that works to reduce anxiety by mimicking GABA’s inhibitory effects to help treat anxiety.

Question 21

(Biological) Relaxation techniques to treat specific phobia
- explain each

Answer 21

Breathing retraining
- A method used to teach someone breathing control techniques that they can apply when facing their phobic stimulus. It can reduce anxiety and relieve symptoms.

Exercise
- Promotes relaxation and therefore relief from anxiety and provides a distraction from the stimulus.

Question 22

Psychological interventions to treat specific phobia
- explain each

Answer 22

CBT
- Assists in changing negative thoughts that perpetuate the phobia. It assists the individual to develop a new understanding that their feared stimuli are not dangerous, so their avoidance behaviours are unnecessary.

Systematic desensitisation
- Used to overcome phobia involving a patient being exposed incrementally to increasingly anxiety-inducing stimuli. It is unlearning the connection between the phobic stimulus and anxiety response.

Question 23

Social interventions to treat specific phobia
- explain

Answer 23

Psychoeducation
- Increases an individual’s knowledge and understanding of a mental disorder and its treatments. The more educated someone is about their disorder, the more control they have over it.
