Theories of Learning
relatively permanent change in behavior brought about by experience.
Classical Conditioning
Being paired with stimulus that naturally brings about that response.
Classical Conditioning (pavlov)
Ivan Pavlov- dogs and salivation, studied digestion. natural response- dog salivate when he sees food. FOOD=UNCONDITIONED STIMULUS.
(US)SALIVATION=UNCONDITIONED RESPONSE. (UR) Example: Bell sounds when food is presented.DOg learns that food would be represented after sound of bell. BELL=CONDITIONED STIMULUS. SALIVATION AS SOUND OF BELL=Conditioned RESPONSE (CR)
Unconditioned Stimulus
Stimulus brings about response without having been learned.
Unconditoned Response
Response that is natural **NEEDS NO TRAINING**
Conditioned Stimulus (CS)
Stimulus, once neutral, paired with US to get response.
Condtitoned Response (CR)
Response thats been learned.**UR=CR**
CR (LITTLE ALBERT)
He played with a rat (neutral stimulus) loud noise scared him. Saw rat when he hear noise-->was scared of rat. SO.
. US(Noise)-->(UR) crying CS(Rat)--->(CR) crying
Extinction
Weakening and eventual disappearance of conditioned response.Example--With dogs----> Present CS over and over without a Uconditoned Stimulus. This cant be done with babies.
Systematic Desensitization
Can be used for phobias.
1. Relaxation training- persons phobia is anxious.-build hierarchy- from least to most.
Spontaneous Recovery
Reappearance of previously extinguished response.
Habituation
In response to stimulus occurring after repeated presentation of same stimulus.
Stimulus Genealization
Only stimulus similar to CS will get a CRex.
Albert wasnt only afraid of white rats but white puppies and kittens as well..
Stimulus Discrimination
If stimulus is diff enough from CS will not get a CREX ALbert not afraid of Brown/black puppy
Higher Order COnditioning
explains more complicated behavior (FOOD) US--> URBell CS--> CS (Bell)
OPERANT CONDITIONING
voluntary response is strengthened/weakened depends on its consequence.
THORNDIKE (OPERANT CONDITIONING) LAW OF EFFECT
Responses that are satisfying are more likely to be repeated, those that arent, ARE NOT LIKELY TO BE REPEATED.
BF SKINNER (SKINNER BOX)
ANIMAL (EX.
RAT) had to operate on environment to get satisfying results. EX-rat presses lever to get food.
REINFORCER
any stimulus that increases probability that preceding behavior will be repeated. (Ex.
Food(REWARD) special attentionshouldnt use toy as reinforcers with children bc they will always expect it.
Primary REINFORCER
satisfies basic biological need. EX FOOD
Secondary reinforcer
Stimulus tht becomes reinforcing bc associated with primary reinforcer. EX MONEY --> used for food.
REINFORCERS USE
Different reinforcer for diff ppl
Positive Reinforcer
Increase bvehavior by adding stimuus
Negative REINFORCER
Increase behavior by REMOVING stimulus
NEGATIVE IS NOT EQUAL TO?
PUNISHMENT
