Q

Describe Watson and Rayner’s study

A

Little albert a 11 month year old boy had no fear of white rats and started to play with it. Each time he went to hold or touch the rat, a metal bar was struck in his ear which produced an UCR of fear. Gradually, little albert associated the fear to the rat and white objects in general

Evaluation of behaviourists explanation of phobias

A

People often have unpleasant experiences but don’t develop a phobic reaction
Studies lack EV
Nomothetic and creates laws for everyone so doesn’t take into account personal differences
Its unlikely two things would be put together to create a phobia

Evaluation of systematic desensitisation

A

It can be used only when a particular phobic object or situation has been identified so only really suitable for specific phobias not social.

Q

Evaluation of the psychodynamic explanation of phobias

A 
Theory is unscientific; unfalsifiable
Middle class women can't be generalised
Only evidence was little hans
Theory is ideographic so focuses on the childhood 
Ignores role of free will

Q

What is the aim of the psychodynamic treatment for phobias?

A

Provide insight into what is unconsciously causing the symptoms of the phobia and requires the person to confront their fears.
Once this conflict is released, the patient can work through it

25
What is free association?
The patient relaxes and says everything that comes to mind. The conflict will be brought into the conscious. Once verbalised, the cause can be explained. The therapist looks for a pattern in the thoughts and is interpreted in terms of unconscious thoughts
26
What is dream analysis?
Repressed ideas which are likely to cause anxiety are more likely to appear in dreams Two contents; manifest content (plot, action, images etc) Latent content; real "meaning" of the dream Therapist identifies what in the unconscious is causing the mental illness Manifest: snake Latent: penis
27
Describe alstorm's study
Assigned 42 social phobics to one of 3 therapies: Psychotherapy; form of free association where fears are spoken about openly Relaxation techniques Drug medication Most significant changes were in psychotherapy rather than the rest Follow up are needed for the effects to be prolonged
28
Examples of freudian symbolism
Long things that 'jut out': penis (mountains, sticks, poles, umbrellas, snakes, trees, baguettes) Entrances: vagina (doors, gates, castle) Curvy objects: breasts (footballs, apples, peaches) Playing: masturbation Rhythmical activities: sex (dancing, climbing, riding) Authority figures: oedipus/electra complex (police, teachers, doctors) Things which go up: erection (aeroplane, helicopters, rockets) Small and round things: nipples (buttons, coins) Penetration(knives, weapons, guns, cannons)
29
Evaluation of psychodynamic treatment of phobias
Tries to find the root of the phobia and is the only therapy that does this Expensive and time consuming and usually takes years to complete Unscientific Could be traumatic for the person as ego defences are broken down and anxiety comes to conscious
30
What is OCD?
A disorder in which a person has recurrent and unwanted thoughts, a need to perform repetitive and rigid actions, or both
31
What is an obsession?
A persistent thought, idea, impulse or image that is experienced repeatedly, feels intrusive and causes anxiety
32
What is a compulsive?
A repetitive and rigid behaviour or mental act that a person feels driven to perform in order to prevent or reduce anxiety
33
What are the main symptoms of OCD?
Recurrent obsessions and compulsions Recognition by the individual that the obsessions and compulsions are excessive or unreasonable Persons daily life is disrupted and is distressed
34
Genetic explanation for OCD
Evidence for twin and family studies suggest that there might be genetic components to OCD
35
Explain McKeon and Murray's study into genetics of OCD
Studied the relationship between OCD and family members. They compared families who had a family member with OCD against families who didn't for the number of others who had it. They found that the person with a family member affected by OCD are twice as likely to have other members in the family with the disorder Providing that genes could be a reason why people suffer from OCD
36
Evaluation of McKeon and Murray's study
Only a small amount of families studied | The results could be down to socialisation instead of genes
37
Explain the serotonin hypothesis
Lack of serotonin is seen as causing OCD Brain deactivates neurotransmitter substances, once they have passed on messages to the next one through producing a chemical called monoamine oxidase. Monoamine oxidase breaks down the chemical ready for it to pass on the next message. Reuptake: the neurotransmitter is reabsorbed by the firing neuron once the chemical has been passed onto the next
38
How is OCD caused by serotonin hypothesis?
Uptake being too good so not enough neurotransmitters are passed across to the next neuron Too much monoamine oxidase is produced
39
2 types of antidepressant drugs?
SSRI: Prozac MAOI: Nardi
40
Evaluation of the role of serotonin
Some people don't respond to the drug treatment Evidence that dopamine plays a part Research that involves the role of serotonin is conducted in labs so is objective and scientific but lacks ev
41
What is the role of the orbital frontal cortex?
PET scans have shown that people with high levels of activity on a part of the left frontal cortex (orbital frontal cortex) High levels of glucose metabolism and blood flow are found here Area of the brain is involved in converting information from the senses into thoughts
42
Evaluation of the orbital frontal cortex explanation for OCD
Difficult to determine whether these high levels of activity in the brain are the cause of this disorder Scientific evidence May explain obsessional thinking but no reasons behind the compulsions
43
Cognitive explanation of OCD; characteristics?
More likely to suffer from depression High levels of moral standards Believe that thoughts are harmful to others Believe they should have complete control over their thoughts
44
What are neutralising thoughts?
A persons attempt to eliminate unwanted thoughts by thinking or behaving in was that puts matters right internally making up for unacceptable thoughts
45
What does the neutralising effect do?
Makes the person feel better and settles the compulsion
46
What are catastrophic misinterpretations?
Think something irrational which is severe and excessively negative which causes anxeity
47
What are Rachman's four steps?
Step 1; presence of obsessional thoughts or images (harming another person) Step 2; catastrophic misinterpretation of the thought (i am a bad person and may end up murdering someone) Step 3; fear and high level of anxiety Step 4; attempts to resist and avoid the thoughts
48
What is hypervigilence?
People with OCD have a "cognitive bias" when attending to environmental stimuli. (extra aware)
49
Explain Rachman's case study
Female participant had a severe fear of diseases, particularly blood. She had catastrophic misinterpretations that she will get aids She scans the environment if in public for evidence of blood, cut and bandages and misperceives red sports for blood. Her hypervigilant scanning meant that she could recall in great detail the blood related items she had encountered
50
Evaluation of cognitive explanation for OCD
4 step model helps to explain how OCD is maintained but doesn't explain why they got the thoughts in the first place Lack of evidence to support the study as it all occurs in the mind its hard to test scientifically Nomothetic, ignores the role of individual differences
51
What is the aim of cognitive therapy?
Replace irrational thoughts with rational ones | Teaches the patient to identify, challenge and replace thoughts with more constructive ones
52
What are the two steps to change conscious thought processes?
Helping people to understand they are misinterpreting their thoughts Making people aware that they need to neutralise their obsessive thoughts by attempting to make amends for having them
53
What are the four steps for conquering OCD urges?
Schwatrz Relabel ; recongise the thoughts Reattribute; realise the thought is caused by OCD Refocus; work around the thought by focusing on something else Revalue; don't take OCD thought at value
54
What is habituation training?
Clients repeatedly think about their obsessive thoughts. the idea that by deliberately thinking about obsessions will become less anxiety-raising with the consequence that compulsive behaviour is not needed to stop the anxiety
55
Describe Rufer's study
Followed 30 inpatients with severe OCD for 6 to 8 years. patients were on various medication and therapies over the years rufer interviewed patients and doctors about symptoms and improvements found that cognitive therapy was found to reduce the frequency and duration of obsessional thoughtd
56
Evaluation of cognitive treatments
The strategies can be practiced any time, outside of the therapy room helping the person maintain their ability to cope Cognitive therapy has been found through follow up studies to be maintained several years after therapy has stopped Cognitive therapy is not suitable for all people because you need to be prepared to be challenged The patient has to be willing to do homework tasks that the therapists set them Lots of studies
57
What is drug therapy?
Neurotransmitters dopamine and serotonin have all been associated with OCD Drugs change the levels of these in the brain SSRI drugs such as Prozac are prescribed to increase the level of serotonin in the brain and MAOI's are sometimes used if there is no benefit from SSRI's
58
What happens if drug therapy doesn't work?
Neurosurgery. Probes in the brain
59
Describe Riddle's study
Wanted to determine the safety and efficiency of SSRI for the treatment of children and adolescents with OCD compares to a placebo. Given either of these each day for up to 10 weeks. Found that there was a 42% reduction of OCD symptoms with the SSRI and 26% for the placebo
60
Evaluation of biological treatments for OCD
SSRIS are easily tolerated and safe, are not addictive Drug treatments are quick and cheap Side effects; nausea, headaches if they come off Take 4 to 12 weeks to feel the benefit If person stops taking the drugs the symptoms can return
