Systematic desensitisation

What is the main assumption of the behaviourist approach?
Normal behaviour is learned through appropriate classical and operant conditioning
1 of 24
What is an example of abnormal behavior?
2 of 24
How are they caused?
When an NS (rat) is paired with a UCS(loud noise)
3 of 24
What new bond is formed?
S-R between the CS(rat) and CR(fear)
4 of 24
How are they're reinforced?
Negitively where voidance of rats mean that the fear is not felt
5 of 24
What does SD aim to do?
Make abnormal behaviour normal through counterconditioning
6 of 24
What is used?
Recipricol inhibition where two opposing emotions fear and relaxation cant be felt at the same time
7 of 24
How does SD work?
breaking the original S-R and reducing the CR fear by establishing an appropriate response(relaxation to the feared object
8 of 24
What happens first?
the client learns how to relax and calm themselves down
9 of 24
How is this usually done?
deep breathing, visualisation and meditation
10 of 24
What does the therapist do after the client can relax?
Draw up the hierarchy of anxiety
11 of 24
What is the hierarchy of anxiety?
a ladder of feared stimuli
12 of 24
For example?
looking at the word rat, a picture of a rat and so on until the person can hold a real rat
13 of 24
What is the third stage of SD?
The client works up through each step of their hierarchy, relaxing at each step where necessary
14 of 24
What is formed at each step?
A new S-R bond is formed
15 of 24
What happens if the client becomes too stressed?
The client will go back down a step on the hierarchy
16 of 24
How is the therapy successful?
When the top step on the hierarchy is reached and the client is able to relax when faced with the thing they feared before the therapy began
17 of 24
SD can be completed using three types of what?
In vivo, In vitro, modelling
18 of 24
What is invivo?
Direct contact with the feared stimuli
19 of 24
What is invitro?
Through imagining the feared stimuli
20 of 24
What is modelling?
seeing a person who does not show a fear response with the feared stimuli
21 of 24
Who suggested that SD was effective?
22 of 24
What was the success rate?
75% in arachnophobia
23 of 24
What does this illustrate?
The behavourist assumption about of learning through classical conditioning has been successfully applied to SD to help treat abnormal behaviour
