Psychopathology Flashcards
What is Psychopathology?
Don’t need to know just useful to read from time to time
Is a broad-ranging field of study concerned not only with the likely causes of and effectiveness of treatments for mental disorders but with more philosophical questions concerning how and why we define others as psychological abnormal and how those labelled as abnormal are treated by society.
What is a Specific (simple) phobia?
Specific phobias are a fear of objects e.g. arachnophobia or situations e.g. aerophobia.
What is Social Phobia?
Social Phobia is a fear of social situations
What are the emotional characteristics of a Phobia?
An extreme, excessive, irrational fear of the phobic object or situation.
What are the Behavioural Characteristics of a Phobia?
Avoidance of the phobic object or situation.
People can also have a stress response (arousal of the autonomic nervous system and fight/flight response or ‘freezing’ in fear)
What are the cognitive characteristics of a Phobia?
Irrational thoughts or fear out of proportion to the real danger posed by the object/situation.
What does Behavioural mean in Psychology?
Ways in which people act
What does Emotional mean in Psychology?
Ways in which people feel.
What does Cognitive mean in Psychology?
Refers to the process of thinking-knowing, perceiving, believing.
What is Depression?
Depression involves the sufferer experiencing either permanently or periodically low mood.
What are the emotional characteristics of Depression?
Sadness, low motivation, loss of interest in normal activities, hopelessness.
What are the behavioural characteristics of Depression?
Poor self-care, loss of appetite/sex drive, social withdrawal, lack of energy, insomnia, suicide.
What are the cognitive characteristics of depression?
Low self-esteem, pessimism, guilt, negative/suicidal thoughts.
What is OCD?
OCD involves experiencing persistent, intrusive, irrational thoughts or obsessions which compel the sufferer to compulsively perform repetitive behaviours.
What are the emotional characteristics of OCD?
Emotional distress and anxiety, embarrassment and shame; an obsession with germs which leads to the emotion of disgust.
What are the behavioural characteristics of OCD?
Compulsive behaviours are performed to reduce the anxiety produced by obsessive thoughts.
E.g. repetitive cleaning and tidying behaviours to reduce the anxiety caused by fear of germs and infection.
What are the cognitive characteristics of an OCD?
Recurrent, intrusive, irrational thoughts often centred on germs, cleanliness, orderliness, doubts and anxieties (that something important has been overlooked), impulses (shouting out obscenities)
What is Agoraphobia?
Phobia of being outside in a public place.
What percentage of the population suffers from OCD?
1.3%
What percentage of the population suffers from Depression?
2.6%
What percentage of the population suffers from Phobias?
2.6%
What does OCD stand for?
Obsessive-compulsive disorder.
What do Behaviourists say?
Behaviourists argue that all behaviours are learnt through interaction with events in the environment.
How do behaviourists explain phobias?
The behaviours which characterise the symptoms of mental disorders are acquired in the same way as any other behaviour the 2-process model and Social learning theory.
Behaviours typical of phobias are avoidance behaviour (external behaviour) and feelings of fear (internal behaviour).
What is the 2-process model?
The two process model argues that phobias are learnt through classical and operant conditioning.
What is Classical Conditioning?
Behaviours are acquired through ‘stimulus-response’ associations: e.g. an event in the environment (stimulus) will cause a physiological effect (response) such as fear.
For example, repeated negative experiences with dogs such as being bitten may lead to a phobic response when you see dogs.
What is Operant Conditioning?
Operant conditioning is a method of learning that occurs through reward and punishment for behaviour. Through operant conditioning, as association is made between a behaviour and a consequence for that behaviour.
How does operant conditioning explain Phobias?
The Phobia is maintained through OC. When a behaviour is reinforced (rewarded) it is more likely to be repeated. Avoidance of phobic objects is rewarding because we avoid the fear we believe they will cause.
This is an example of negative reinforcement as we are being rewarded for escaping an unpleasant situation.
For example, the behaviour of not taking a lift to avoid claustrophobia strengths the behaviour of not taking lifts as one avoids the anxiety that would occur if one did take the lift.
How do behaviourists say Social Learning Theory can cause Phobias?
SLT would also emphasise how fears can be learnt from parents via observations and imitation.
An infant may either:
Simply imitate a behaviour:
e.g. mother’s phobic behaviour (modelling)
or,
Imitate a behaviour because they expect a reward (vicarious learning):
e.g. seeing one’s mother being given care after a phobic response so imitating her hoping to receive the same reward.
What was the Watson 1920 study?
Watson 1920 classical conditioned a phobia of a white rat in an 11-month old boy named Little Albert.
What was the procedure of Watson 1920?
At the beginning of the study he showed no fear of white fluffy objects such as cotton wool, a white rat and a white rabbit these were neutral stimuli. Watson presented the white rat to Albert whilst scaring him by banging metal bars together to create a frightening noise. This was done 3 times then repeated a week later.
From then on, whenever Albert was shown the white rat without the noise he began to cry as he generalised this fear to other similar white, fluffy objects.
What were the findings of Watson 1920?
Watson claimed Phobias were classically conditioned through negative stimulus response associations between objects (the stimulus) and the fear (the response)
What evaluation is there supporting Behaviourists explanations for Phobias?
Watson 1920 study on Little Albert claimed that Phobias were classically conditioned through negative stimulus response associations between objects and the fear, supporting Behaviourists explanations that classical conditioning causes phobias.
What evaluation is there against Behaviourist explanations for Phobias?
(There is 2, only need to say one.)
Fears may be evolutionarily determined and genetically inherited to help us avoid and escape potentially dangerous situations and animals. This seems clear from the fact that the most common phobias -snakes, rats, heights, etc are potentially dangerous. This is supported by Seligman who used the concept of ‘biological preparedness’ when examining phobias. He found that rats could easily be conditioned to avoid-life threatening stimuli such as toil liquids or electric shocks, but could not be easily conditioned to avoid non-harmful stimuli such as flashing lights. This provides evidence against Behavioural explanations in that it seems to suggest that phobias are innate, not learnt and it explains why particular types of phobias are more common.
Many people have bad experiences with stimuli but do not go on to develop a phobia, and many people develop a phobia despite having no previously negative experiences with their phobic object. Behavioural explanations argue that we develop phobias of objects we have frightening experiences with, e.g. guns or cars. However, phobias of these stimuli are extremes and despite the fact that most people rarely encounter snakes, this phobia is very common.
What is Systematic desensitisation?
Systematic desensitisation is a type of behavioural therapy based on the principle of classical conditioning.
It was developed by Wolpe during the 1950s. This therapy aims to remove the fear response of a phobia, and substitute a relaxation response. It can be used to treat both simple and social phobias.
What are the four steps of Systematic Desensitisation?
1-
The client and therapist will draw up an ‘anxiety hierarchy’ of situations that cause anxiety, from minor discomfort to major suffering.
2-
The therapist induces a state of deep relaxation in the client using progressive muscle relaxation, hypnosis or tranquillisers.
3-
In this relaxed stat the client is repeatedly exposed to the 1st step on the anxiety hierarchy until feelings of anxiety are replaced by relaxation.
4-
The client gradually progresses upward through the stages of anxiety hierarchy until their most feared situation is paired with relaxation rather than anxiety.
