Psychopathology (general) Flashcards
What are some behavioural characteristics of phobias?
Panic, avoidance, and endurance
What are some emotional characteristics of phobias?
Anxiety, unreasonable responses
What are some cognitive characteristics of phobias?
Selective attention, irrational beliefs, cognitive distortions
Explain how phobias are acquired through classical conditioning
We associate something which we have no fear of with something which naturally elicits a fear response. This leads to a fear of the initially neutral object. For example, in the Little Albert study, Albert associated a white rat with a loud noise, causing his fear of the rat.
Explain how phobias are maintained through operant conditioning
When an individual avoids their phobia, they are negatively reinforced with decreased anxiety. This means they are more likely to avoid their phobia in the future.
What are two limitations of the classical conditioning explanation for phobias?
It does not explain why some phobias are more common than others.
It does not explain phobics who have never had a traumatic experience with their phobia.
What is a strength of the operant conditioning explanation for phobias?
Therapies which involve deliberate exposure to the phobia stop the process of negative reinforcement. These therapies have been found to be successful, supporting the claim that negative reinforcement maintains phobias.
What is one strength of the Little Albert study?
It was a well-controlled lab experiment, which means that we can be confident that the conditioning did in fact cause the phobia.
What is one weakness of the Little Albert study?
It is an individual case study, so it may be that Albert is an easily conditioned outlier, making the findings ungeneralisable.
What did DiNardo et al. discover about phobias?
Over 60% of dog phobics related their phobia to a particularly frightening event. However non-phobics reported a similar proportion of such experiences. This shows that factors other than classical conditioning must affect phobias.
Describe the process of systematic desensitisation
1) The phobic creates an ‘anxiety hierarchy’ in which they list situations from least to most anxiety producing
2) The phobic is taught relaxation techniques, such as meditation and breathing exercises
3) The phobic is exposed to the situations on their hierarchy, one at a time, using the relaxation techniques between each step, until they feel relaxed in their most anxiety producing situation
Describe the process of flooding
The phobic is exposed to their highest anxiety producing situation straight away. For example a person with arachnophobia may hold a spider in their hand.
Describe Smith and Glass’s meta-analysis on phobia treatments
They found that systematic desensitisation was the most effective treatment, with an effect size of 0.91. The meta-analysis took results from 223 studies into SD, meaning that it is unlikely the result is a fluke.
Describe Gilroy et al.’s study into systematic desensitisation
They followed up on 42 arachnophobics after being treated with systematic desensitisation. He found, using a ‘spider questionnaire’ and exposing the group to spiders, that they were less fearful than the control group, who were treated with relaxation therapy. This suggests that SD is effective.
Describe Barlow’s meta-analysis into flooding and systematic desensitisation
Barlow conducted a meta-analysis using findings from studies into flooding and systematic desensitisation, and found that they were equally effective.
What is one limitation of flooding?
It can be traumatic for the phobic
What is one limitation of systematic desensitisation?
The phobic has to undergo lots of sessions
Explain the ‘evolution-preparedness’ explanation of acquiring phobias
We have an innate disposition to acquire phobias of things which were threats to our survival in our evolutionary past. This explains why some phobias are more common than others.
Describe Garcia and Koelling’s study into the ‘evolution-preparedness’ explanation for phobias
They gave rats a sweet-tasting drink paired with either a drug that made them sick or an electric shock. The rats acquired a dislike for the drink more quickly with the drug, as sickness is part of our evolutionary past, whereas electric shocks are not.
What is a limitation of the ‘evolution-preparedness’ explanation of acquiring phobias?
It does not explain phobias relating to modern things like cars, or to harmless things like bellybuttons
Explain the ‘genetics’ explanation of acquiring phobias
Some people may inherit genes which make them more likely to acquire a phobia. This explain why some people acquire a phobia after a traumatic incident while others do not.
What is a limitation of the ‘genetics’ explanation of acquiring phobias?
Twin studies which have been done on the subject have produced contradictory, inconclusive concordance rates.
Explain the social learning theory explanation of acquiring phobias
We observe models showing a fear of something, and we acquire the same fear vicariously. This explains why some phobias are more common than others, and why some people have phobias without having a traumatic experience linked to it.
Describe Leib et al.’s study into the social learning theory explanation of acquiring phobias
They investigated children with phobias and found that they were likely to have parents with similar phobias. In this case, the parents are the role models.
When can flooding be an inappropriate treatment?
For certain phobias like social phobias, and certain people, like those with learning difficulties.
What are some behavioural characteristics of depression?
Low activity levels, disruption to sleeping/eating patterns, and self-harm
What are some emotional characteristics of depression?
Low mood and self-esteem, and anger
What are some cognitive characteristics of depression?
Poor concentration, dwelling on the negative, absolutist thinking
Describe Beck’s cognitive theory of depression
Some people think in ways that make the cognitively vulnerable to depression. When faced with the same situation as someone else, they will think differently and more negatively.
