1. APPROACHES
Origins of Psychology
Wilhelm Wundt
o Opened the first experimental psychology lab
o Became the first person to be known as a psychologist
o Believed in reductionism
o Studied the structure of the mind
Introspection
o Process by which a person gains knowledge about their own mental and emotional states
o Allows us to observe our inner world
o Can be done with sufficient training
o Memory, perception and thoughts
The Learning Approach: Behaviourism
Behaviourist Approach
Behaviour is observed and measured
Basic processes for learning are the same in all species
o Animals could replace humans as experimental subjects
Classical conditioning and operant conditioning
Classical conditioning
Stimulus response learning
Association between two stimuli
Pavlov:
o Noticed that animals not only salivated with food, but with things associated with food (his
assistant who fed his dogs)
o Unconditioned stimulus (food) – natural stimulus
o Unconditioned response (salivating) – triggered by stimulus
o Natural stimulus (bell) – something that initially gives no response
o Conditioned stimulus (bell) – something learned to trigger a response
o Conditioned response (salivating) – triggered by stimulus
Operant conditioning
Behaviour is maintained by consequences
Reinforcement and punishment
Skinner:
o Taught animals, such as rats or pigeons
o Reinforced rats using food pellets
o Food only released if rats pulled the lever when the red light was on and not when the green
light was on
o Quickly learnt to press the lever when the red light was on
Categories/Types of Punishment
Positive reinforcement
o Receiving a reward when a certain behaviour is performed
o Increases likelihood of behaviour
Negative reinforcement
o When an animal or human avoids doing something unpleasant
o Increases likelihood of behaviour
Punishment
o An unpleasant consequence of behaviour
o Decreases likelihood of behaviour

, Social Learning Theory
Bandura (1977) – argued that classical and operant conditioning could not account for all human
learning
Important mental processes mediate between stimulus and response
Learning through observation and imitation
Steps in observational learning:
o Modelling – behaviour is modelled by a role model
o Observation – behaviour is observed
o Imitation – behaviour is imitated and therefore learned
o Identification – observers must identify with the role model in order to imitate them
Live models: parents, teachers, friends
Symbolic models: someone portrayed in the media
o Vicarious reinforcement – we are more likely to repeat a behaviour if we see the model
being rewarded for it
Observing the consequences
Mediational processes – mental factors that mediate to determine whether a new response is
acquired
o Attention – the behaviour has to grab our attention
o Retention – the behaviour has to be remembered
o Motor reproduction – the person needs to believe they are capable to perform the behaviour
o Motivation – the person needs the will to perform the behaviour, usually determined by
whether the behaviour was rewarded or punished
Key Study: Bobo Doll
Procedure:
o Group of children – half were exposed to footage of an adult model interacting aggressively
with a life-sized Bobo doll
o Aggressive model:
o Physically assaulted the doll
o Used verbal words of aggression, e.g. ‘POW’
o Half exposed to non-aggressive models
o After watching the video, the children were frustrated by being shown toys they weren’t
allowed to play with
o Then taken to a room where, along other toys, there was a Bobo doll
Findings:
o Aggressive model reproduced a good deal of physically and verbally aggressive behaviour
o One third repeated the verbal responses
o Non-aggressive model exhibited no aggression
o Children who saw the model being rewarded were more likely to implement this in their own
play
o Same sex models were more likely to reproduce behaviour
