Pavlov focussed on..
classical conditioning.
what is the food in pavlov experiment
unconditioned stimulus
what is salivation in pavlovs experiment
unconditioned reaction
what is a conditioned stimulus
initially neutral to organisms but over time evokes reaction, THE BELL
classical conditioning main point
pairs conditioned stimulus ( bell ) with unconditioned stimulus (food) and untimely the unconditioned reaction happens without conditioned stim. ( turning UCR into a CR by repeatedly pairing UCS with CS )
classical conditioning in humans
phobias ( response to feared stimulus )
dad sighs before hitting so you get a conditioned response ( fear ) from him sighing
stimulus generalization
stimuli that are like the conditioned stimulus elicit the same reactions. -> could get a phobia from sighing or breathing sounds
how would a behaviorist try to help you overcome a phobia
put you in relaxed state and make sighing noises so you don’t feel tense when you hear them ( using classical conditioning to redesign the brain )
Who runs OPerant conditioning
BF skinner
distinction between classical conditioning and operant conditioning ( as skinner says )
classical - elicited behavior ( reflexive reaction to a stimulus ), automatic reactions, skinner says stimulus response psychology
operant - emitted behaviors ( actions where organism initiates a behavior with no obvious preceding stimulus ),
operant conditioning ( as bf skinner says )
consequences of emitted behavior affects its future likelihood.
response stimulus psych
there is an action, following an action there is a stimulus
positive reinforcement
positive stimulus follows behavior
is negative reinforcement a rewarding experience ?
yes, taking away a negative stimulus is good.
negative reinforcement
removal of a negative stimulus following behavior
