what did pavlov condition his dog to do
salivate when he heard the bell ring even when he didnt see food
pavlov experiment terms
food = US. salivation to food = UR. bell = CS. salivation to bell = CR
2nd order conditioning
once a CS has acquired a conditioned response, it can also act as if it is a US itself
acquisition
repeated presentations of the CS with the US that results in an increase in the CR
extinction
repeated CS alone presentations following acquisition resulting in a reduction in the CR
how does classical conditioning relate to human psychology more generally
classical conditioning as an experimental model for studying learning processes
the CR is not always the same as
the UR
food preferences and place preferences are
appetitive conditioning
conditioned fear, conditioned taste aversions, place avoidance are
aversive conditioning
conditioning in advertising
pairing of a product (CS) with desirable qualities (US)
exposure therapy and extinction for
removing phobias
edward lee thorndike’s puzzle box
had an animal in it with a release pedal and good outside the box. observed the progressive improvement in time for the animal to escape
thorndike’s law of effect 1911
what a human/animal does is strongly influenced by the immediate consequences of such behaviour. if an action is met with satisfaction, the organism will be more likely to make the same action next time
radical behaviourism
SKinner and Watson, rejection of anything unobservable
reinforcers
events that result in an increase in a particular behaviour
secondary reinforcers
acquire their reinforcing properties through experience
social reinforcement
e.g. praise
shaping
reinforce behaviours that are closer and closer to a target behaviour and gradually make the conditions of reinforcement more precise
what affects instrumental learning
partially reinforced responses
partially reinforced response
some form of response from an action, not necessarily positive or negative
reinforcement schedules
ratio, interval
ratio reinforcement schedule
fixed- you have to do something a certain amount of times to get a reward
variable - e.g. saleswrk. the more doors you knock on the more chance someone will sign up eventually
interval reinforcement
fixed - fixed amount of time between reinforced response. variable - doesnt know how long between each response will be reinforced
