Approaches Flashcards
Behaviourism Assumptions
All behaviours are learned from our envrionment.
Focuses on observable behaviour.
Animals and humans learn in the same ways, experiment on animals.
Should be scientific and objective - use labatory experiments.
Classical Conditioning
Pavlov
Learning through association.
Dog experiment.
Operant Conditioning
Skinner
Learning by consequences.
Learning is an active process - consequences dictate if behaviour is repeated.
Operant Conditioning - reinforcement
Posisitve Reinforcement - receiving an award.
Negative Reinforcement - Stopping something unpleasant from happening.
Punishment - Unpleasant consequence.
Operant Conditioning - Skinner box
Rat in cage, activating lever meant a food pellet fell into the food dispenser (positive reinforcement). Rats quickly learnt to go straight to the lever. Showing positive reinforcement increases likelihood of behavior being repeated.
Same for negative reinforcement (electric shock).
Behaviourism Application
Systematic Desensitisation - counter-conditioning process for people with phobias.
Token Economy - Effective in managing psychiatric patients, by reinforcing certain behaviours.
Behaviourism Evaluation
Experimented on animals - hard to generalise (low population validity).
Scientific methods - high control, lack of extraneous variables, replicable, objective. MIAD: demand characteristics, ecological valdity.
Environmental reductionism - broken down to simple stimulus-response associations. Biological factors (neurotransmitters)
Social Learning Theory
Bandura
Learn through observation and imitation.
Focus not only on behaviour but also mental processes involved, so not a pure behaviourist theory.
SLT - Meditational Processes
ARRM
Attention - needs to pay attention to behaviour and consequence so create a mental representation of behaviour.
Retention - Storing observed behaviour in LTM.
Motivation - must expect to receive the same posistive reinforcement for imitating modelled behaviour.
Reproduction - must have the ability to reproduce observed behaviour.
SLT - Vicarious Reinforcement
Imitation is more likely to occur if model recevied positive reinforcement.
Imitation is also more likely if one identifies with the model.
SLT - study
Bandura’s bobo doll study.
Lab experiment, 36 boys and girls, aged 3-6.
Group 1 - model hit and shout at doll.
Group 2 - non-aggressive model.
Group 3 - no model.
Taken to room full of toys but told not to play with them.
Taken individually to room containing bobo doll and various toys, some aggressive.
Group 1 more aggressive, specific aggressive acts.
Repeated with vicarious reinforcement method.
SLT Evaluation
Lab studies - hard to generalise to everyday life (ecological validity) + unfamiliar envrionment so demand characteristics.
Can explain differences in culture - behaviour is imitated.
Older children and adults may behave differently as they have more developed moral values.
Behaviourism (SLT) I+D
Nature vs Nurture
Nature - behaviour is learned from our environment and external role models.
Cognitive Approach
Focused on how mental processes affect behaviour, argues internal mental processes should be studied scientifically.
Influenced by developments in computer science and analogies are often made.
Interested in how the brain inputs, stores and retrieves information.
Cognitive Approach - Assumptions
Information received from our senses is processed by the brian and this directs how we behave.
Internal mental processes cannot be directly observed, but we can infer what a person is thinking based on how they act.
Cognitive Approach - Schemas
A schema is a cognitive framework that helps us organise and interpret information.
Based on previous experience and gets more detailed as you get older.
Cognitive Approach - Role of Schemas
Cognitive processing can often be affect by schemas.
Help us to interpret incoming information effectively. Prevents us from becoming overwhelmed by the vast amount of information.
However, can lead to distortion of this information as we select and interpret environmental stimuli using schemas that might not be relevant. (eyewitness testimony).
Cognitive Approach - Emergence of neuroscience
Aims to find out how brain structures influence the way we process information.
Maps cognitive functions to specific areas of the brain (fMRI, PET).
Example: Braver - central executive situated in the prefrontal cortex.
