psychology approaches Flashcards
what approach did Wundt use?
structuralist and reductionist
what method did Wundt use?
introspection
what is introspection?
analysing your own thoughts internally, pts asked to describe their experiences when presented with a set of stimuli and their reactions were recorded
what are the problems with introspection
doesn’t explain how the mind works
what was Griffiths study using introspection
investigated people who gambled regularly with those who did not. proposed that the thought process of gamblers would be more irrational than non gamblers. pts were told to think aloud when playing the fruit machine game. as expected, gamblers thoughts were more irrational
evaluate Wundts methods (strengths)
+ - methods are still used in useful ways in more recent research. a study was done into teenagers response to a beep, where they had to say their thoughts out loud, when focused on a challenging task, teenagers were more upbeat, this could improve their quality of life
+ - his work paved the way for later controlled research and was very influential in psychology as a science , helping it to be recognised as a science
evaluate Wundts methods (weaknesses)
- we have little knowledge of the causes and processes underlying our behaviour (eg - people may not be aware of their own stereotypical thinking) causing introspection reports to be inaccurate. furthermore, pts might have thoughts they consider as undesirable and therefore lie.
- studies unobservable mental processes so his theories are unfalsifiable. this means that its difficult to test the ideas scientifically so cannot be falseifiable
whats the behaviourist approach
argues that psychologist must focus on observerable events rather than internal events, as it is more objectively measured
how does behaviourist approach believe learning occurs
classical conditioning
operant conditioning
what is classical conditioning
learning by association
how discovered classical conditioning
Pavlov
what did pavolov find with his dogs
noticed dogs didn’t only salivate when food was placed in their mouth, but also salivated in reaction to stimuli that was present at the same time as food
what happens before classical conditioning
unconditioned stimulus (food) > unconditioned response (saliva)
a tone was established that didn’t make them salivate
tone= neutral stimulus
what happens during classical conditioning
presented tone with food
unconditioned stimulus (food) + neutral stimulus (tone) > unconditioned response (saliva)
what happens after classical conditioning
conditioned stimulus (tone) > conditioned response (saliva)
what is operant conditioning
learning by consequence of behaviour
whos idea is this
skinners
how does learning happen in operant conditioning
through reinforcement
what are the types of reinforcement
positive
negative
what is positive reinforcement
occurs when behaviour produces a consequence that is pleasurable and therefore increases likelihood of a response occurring because it involves a reward for the behaviour
what is negative reinforcement
increases likelihood of a response happening because it involves the removal of unpleasant consequences - doing something to stop a bad thing happening
what was skinners box investigation
rat moves around the box and accidentally presses a lever to receive food, which is a reward. this is positive reinforcement. another version of the box delivers an electric shock through the box, the rat learns to press the lever to stop it. this is negative reinforcement
evaluate behaviourist approach (strengths)
+ - concepts have real life application. classical conditioning has led to the treatment of various phobias, fear and relaxation being response and conditioned response
+ - operant conditioning has led to token economy system being successfully used in institutions (eg - prisons), reward appropriate behaviour with tokens that can be exchanged for privileges
+ - increased scientist credibility of psychology by using lab experiments and focusing on observable behaviour within highly controlled settings
evaluate behaviourist approach (weakness)
- most research is carried out on animals so cannot be generalised to humans
- reductionist, reduces complex human behaviour down to only learning through rewards and associations
- deterministic - our past experineces will produce behaviour , this does not allow any free will we may have over our behaviour
what is the social learning theory
people imitate the behaviour of ‘models’ behaviour is learnt faster through them
what increases the likelihood of imitating behaviour
- if they identify with the model
- they believe they have the ability to reproduce that behaviour ( self efficacy)
- vicarious reinforcement - see another person rewarded for certain actions
what are the fourth components of the SLT
- attention
- retention
- motor reproduction
- motivation
explain the first phase of SLT
ATTENTION - individuals need to perceive and attend to significant features of modelled behaviour
explain the second phase of the SLT
RETENTION - in order to reproduce modelled behaviour, the individuals must code the information into long term memory
exaplain the third phase of the SLT
MOTOR REPRODUCTION - observer must be able to reproduce models behaviour
explain the fourth phase of the SLT
MOTIVATION - in this process, the observer expects to receive positive reinforcements for modelled behaviour
keys study in SLT
Bobo doll study -
72 children, 1/2 boys and 1/2 girls - there were three conditions and the children were matched on aggression. one group watched an aggressive model hitting a bobo doll with a hammer and punching it saying saying pow and boom. the second group saw a non aggressive model that played quietly in corner of the room. the third had no model (control group)
found group 1 frequently imitated acts of the same aggression whereas the other two groups showed very little aggression
evaluate SLT (strengths)
+ - CC OR OC can offer an adequate account of learning on their own, SLT provides a more comprehensive explanation of human learning by recognising the importance of cognitive mediational process
+ - real life application - SLT can explain criminal behaviour = strongest cause of violence in adolescents was because they saw it modelled and rewarded
evaluate SLT (weakness)
- bobo study done in a lab - cannot be generalised to real life
- causality - theory suggests that watching the aggressive, however it may be adolescents who already have deviant attitudes seek out deviant role models
- reductionists - too simple to argue that behaviour is only learnt through imitation
