Psychology - Approaches Flashcards
Classical conditioning
Learning through association
Operant conditioning
Learning through consequences
Classical conditioning - Study
Pavlov
dog - lab experiment
unconditioned stimulus- food
unconditioned response- salivation
neutral stimulus- bell
association between the two created aconditioned response
Positive reinforcement
Receiving a reward
Negative reinforcement
Occurs when performing an action stops something unpleasant happening
Operant conditioning - Study positive
Skinner
rat placed in a cage
if lever was puller get food pellet- positive reinforcement
rats learned this behaviour after a few attempts
What did Skinners study show?
Positive/ negative reinforcement increases the likelihood of behaviour being repeated
Operant conditioning -Study negative
Skinner
rat placed in a cage rigged with elect plates at the bottom
if rat hit lever the electrical current will stop - negative reinforcement
rat learned to go straight to the lever for the electrical current to turn off.
Application of behaviourism
Behaviourism has increased our understanding of the causes of phobias and attatchment
given a rise in therapies such as systematic desensitisation and token economy
Behaviourism - AO3 - phobias
Watson and Rayner showed that phobias can be learned through classical conditioning - little albert
AO3 - behaviourism - Methods
Scientific- lab experiment
reliable and can be replicated
high control of extraneous variables
AO3 - behaviourism - biological factors
ignores the role of neurotransmitters
e.g low level of serotonin can rise depression
high level of dopamine is involved in OCD
Issues and debates - Skinner
Skinner says that free will is an illusion and our behaviour is based on previous conditioning
Social learning theory
learned through experience - through observation and imitation of others
Mediational process
Attention, retention, motor reproduction, and motivation
Attention
the individual needs to pay attention to the behaviour and its consequences and form a mental representation of the behaviour
Retention
storing the observed behaviour in LTM where it can stay for a long period of time, imitation is not always immediate
Reproduction
the individual must be able to reproduce the observed behaviour - ability and skill
Motivation
individual must expect to receive the same positive reinforcement for imitating the observed behaviour
Imitation occurs when…
if the model is positively reinforced - vicarious reinforcement
if we identity with the model
Bobo doll study - Bandura et al - aims
conduct a controlled experiment to investigated if social behaviour can be learned through observation and imitation
Bobo doll study - Bandura et al - sample
36 boys and 36 girls aged between 3-6
Bobo doll study - Bandura et al - groups
Group 1 -12 boys 12 girls shown a model hitting the doll with a hammer and shouting at the doll
Group 2 - 12 boys 12 girls shown an non-aggressive model
Group 3 - 12 boys 12 girls control group not shown a model
children then taken to a room and told not to play with the toys - aggression arousal
Bobo doll study - Bandura et al - Results
the children who observed the aggressive role model were more aggressive than the children from the other two groups.
Group 1 imitated specific acts that were displayed by the model.
Boys imitated more physically aggressive acts than the girls.
There was no difference in verbal aggression between girls and boys.
Bobo doll study - Bandura et al - conclusion
This supports SLT as it shows that children imitate the behaviour of role models even if the behaviour is aggressive.
Bandura and Walter - experiment - sample
All children were shown an aggressive role model just diiferent consequences
Group 1 - the model was praised
Group 2 - the model was punished
Group 3 - no consequences
Bandura and Walter - experiment - results
when left on their own group 1 showed th emost aggression followed by group 3, group 2 was the least aggressive
Bandura and Walter - experiment - conclusion
This shows that imitation is more likely to occur when the role model is positively reinforced, demonstrating the importance of vicarious reinforcement
SLT - application
Explains the influence of media on behaviour
James Bulger murder
The perpetrators were children themselves and claimed they were influence by the film Child Play 3
However these children had bad role models - could have witnesses real- life violence and social deprivation
SLT - Evaluation
supported by two studies - badura et al and bandura and walter
Can be explained the difference between behaviour different cultures.
A more complete explanation of human behaviour than conditioning as it takes in to account of cognitive factors in learning, it does not take in to account of free will and moral values.
Cognitive approach
Focused on how our mental processes affect our behaviour
Cognitive psychology
Influenced by developments in computer science and analogies are often made between how a computer works and how we process information
Computer analogy
How the brain inputs, stores and retreives information - multi-store model of memory
Schemas
A mental framework of beliefs and expectations developed from experience (packet of information) helps us organise and interpret information
Weakness of schemas
It can lead to distortion of information as there is too much environment stimuli
E.G. eye witness testimony, and optical illusions
Cognitive neuroscience
Scientific study of brain structures on mental processes
Neuroscience
Aims to find out how brain structures influence the way we process information and map mental cognitive fuctions to specific areas of the brain
Example of brain mapping
Braver et al 1997 found that when their participants were performing activities involving central executive while being scanned, the pre-frontal cortex showed greater activity. Suggests that the central executive is situated in the pre-frontal cortex.
