behavioural approach Flashcards
what are the three approaches?
-we are all born into the world as a blank slate
-all behaviour is acquired through the process of conditioning
- same laws apply to human and non-human animal behaviour
SEE we are all born into the world as a blank slate
S- When we are born our mind is effectively a blank slate a tabula rasa. this means we are not born with any pre-prepared mental content.
E-this means that our personalities and behaviour are a product of interactions with our environment. we are shaped as a result of each experience we have.
E- an example is from the study of Little Albert. prior to the W&R trial, Albert had no pre-pre-prepared reaction to the rat (NS) following paired presentation with a loud noise (UCS) he had become extremely fearful. (CR)
SEE all behaviour is required through the process of conditioning
S- Classical conditions learnt through association and operant conditioning is learnt through reinforcement
E- (C) pavlov conditioned dogs to salivate to the sound of a bell. this outcome was created through joint stimulation of an unconditioned stimulus and a neutral stimulus (bell) over several trials. Salivation to the sound of the bell was a learnt response (conditioned) (O) Skinner demonstrated the positive reinforcement led to an increase in the frequency of target behaviour whereas punishment leads to a decrease in target behaviour
E- an example of conditioning affecting human behaviour can be seen in the acquisition of phobias. people can develop a phobia of dogs after being bitten as they’ve learnt to associate the dog with being bitten and the pain
SEE same laws apply
S- laws of learning are believed to be same for humans and non-human animals. it is impossible to study animal learning in the laboratory and make generalisations to human behaviour
e- as behaviours do not look to the impact of emotions, thoughts or biological structures, they can assume that animal/human behaviour is subject to the same influences. animals/ humans use the same basic building blocks for learning, only humans have more of them
E- token reward systems- operant conditioning principles developed in the confinement of the lab with animal, also applied in controlling prisoner behaviour with token reward systems. the desirable behaviour is rewarded
freewill/determinist
S/W
application
behavioural
determinism, sees an individuals behaviour as being a product of uncontrollable external factors.
weakness
determinism example in this approach behavioural
the rewards and punishments we have been provided with are beyond our control. we cannot determine our behaviour as we do not choose the environment that we are born into
reductionist/hollistic
S/W
application
reductionist, the behavioural approach would disregard biological influences
only behaviour and the outcomes of interactions with our environment are important
practical applications
S/W
application
hugely successful treatments/therapies
S
practical application examples in the approach
systematic desensitisation is extremely effective in the treatment of phobias. based on classical conditioning
75% of patients with phobias responded to SD
idiographic/nomothetic
S/W
application/ why is it problematic
individuals are thought to learn all of their behaviours in the exact same way (conditioning) no variation
problematic as no treatment will work for everyone
SD is not 100% effective for all phobias
nature/nurture
s/w
application
nurture, behaviour focuses solely on the surrounding environment as a cause of shaping behaviour
behaviourist would not consider how our genes may have contributed to out personality/behaviour
example of nurture
behavioural psychologist would say that depression is caused by the individuals surroundings, not the fact that they could have a lack of serotonin in your brain
scientific/non-scientific
S/W
application
scientific
advantageous as it allows us to differentiate beliefs and real facts
this makes the assumption of the behavioural approach much harder to argue against as they are supported with evidence
strength
therapy
systematic desensitisation
what does systematic desensitisation involve
therapy based on classical conditioning, it involves counter conditioning, where the therapist attempts to replace the fear response with a relaxation response in presence of the phobia. we can’t be both fearful and relaxed at the same time, a hierarchy of increasingly fearful situations are used
describe the processes of systematic desensitisation
- an anxiety hierarchy is established, where the therapist would ask the individual to list situations from the least to most fearful, in spider phobics least fearful might be seeing a picture of a small spider, most would be finding a tarantulala in their bed
2 erapist trains the client in deep relaxation techniques - therapist ask the client to visualise the least feared situation. they will perform the deep relaxation procedure
- once the client feels comfortable at that level, they are asked to imagine the next situation in the hierarchy
- over a series of sessions that client will cope with every level, although they can stop at any time and restart at a lower level. eventually they can cope with the most feared situation
evaluation of therapy
effectiveness strength
extremely effective in treatment of simple phobias Barlowe et al. success rates of between 60-90% have been reported for spider & blood injection phobias.
McGrath et al. reported that about 75% of patients with phobias responded to systematic desensitisation
suggesting SD may be vital in improving quality of life for phobic individuals
evaluation of therapy
effectiveness weakness
fails to treat all phobias, especially ones with an evolutionary survival concept
Ohman et al. says that SD is not effective for all phobias. eg, heights, dark.. as they are not phobias as result of personal experiences
SD may be of limited effectiveness and may only be successful in treating some phobias
evaluation of therapy
ethical strength for
behavioural
more ethical than other behavioural therapies (flooding)
in SD each step is conducted slowly and at a pace dictated largely by the client. therapist can see whether the client is fully relaxed at each stage of the therapy. therapist must only move up the hierarchy when the client is completely ready. suggesting it’s highly ethical, patients well being is being looked after
evaluation for therapy
ethical weaknesses
during treatment clients are subjected to lots of fear/anxiety. using this therapy to treat phobias results in a high level of discontinuation from pps because of the high level of stress (may do more harm than good) Barlow and Duand (1989) sugest subjecting suffers to SD could make their phobia worse.
may be failing to protect their well being
evaluation
conclusion
overall the biggest strength is that there is a success rate of 75% of the cure of phobias. the biggest weakness from the evidence above is that it fails to protect some peoples well-being due to anxiety caused. based on the evidence it is clear that SD is effective but isn’t ethical as it should be
methodology
Watson and Rainer
-W and R said it was an experiment but it was actually a controlled observation, took part in a controlled environment
sample: one pps (LA) he was familiar with hospitals as his mother was a wet nurse. he was a baby aged 9 months and was described as a male infant who was unemotional and stolid. sample was obtained by opportunity samplinf
aim of Watson and Rainers study
to test whether classical conditioning could be used to programme a fear response into an infant
