  • Main assumptions:
    Behaviour is learned through experience.
    Only observable behaviour is measured scientifically and only these behaviours should be studied.
    Animal research is valid - tabula rasa
  • Classical conditioning is learning by association.
  • Classical conditioning is passive
  • Stimulus generalisation is when a stimulus becomes generalised to other related stimuli assosicated with conditioned response
  • Stimulus discrimination is when a stimulus is not associated with a conditioned response as it's too different
  • Time continguity means the UCS and NS need to be presented at the same/close to the same time
  • Classical conditioning schedule:
    UCS -> UCR. NS ->UCR
    UCS + NS -> UCR
    CS -> CR
  • Operant conditioning is learning by reinforcement or punishment
  • Positive reinforcement

    addition of a stimulus which encourages behaviour to be repeated
  • Negative reinforcement
    removal of a stimulus which encourages behaviour to be repeated
  • Punishment decreases chances of behaviour reoccurring
  • Skinner
    used operant conditioning to encourage a rat to press a lever in response to specific visual and auditory signals
  • Pavlov
    classically conditioned dogs to salivate on the sound of a bell ringing
  • Skinner: Positive reinforcement
    rat presses lever > rat rewarded by food > rat presses lever again > food is a positive reinforcement that strengthens lever pressing behaviour
  • Skinner: Punishment
    rat presses lever > punished with shock > rat avoids pressing lever > shock acts as a deterrent and weakens lever pressing behaviour
  • Skinner: Negative reinforcement
    light on before floor becomes electrified and rat presses lever > rat rewarded with shock ending > rat presses lever when light comes on to prevent shock > end of shock acts as negative reinforcement and strengthens lever pressing behaviour
