    after repeatedly being paired with the unconditioned stimulus, it

    causes the same reflexive response, making it CONDITIONED

    STIMULUS [CS] .

    4. CONDITIONED RESPONSE : comes as a response to the conditionedstimulus, so the response may not be as strong as the unconditioned

    response.

    BASIC PRINCIPLES The conditioned stimulus must come before the unconditioned

    stimulus. Both stimuli must come almost simultaneously [ ANTECEDENT

    STIMULI ]. Longer interval, no response, but it depends on the natureof the conditioning task.

    Neutral stimulus must be paired with the unconditioned stimulus

    before conditioning happens. The conditioned stimulus is distinctive and it must stand out from

    other competing stimuli.

    STIMULUS GENERALIZATION : Similar stimulus to the conditioned

    stimulus will not cause exactly the same responsethe closer it is the

    conditioned stimulus, the closer the response.

    STIMULUS DISCRIMINATION : Pavlov did not give dogs food if they

    responded to a general stimulus, and they learned the exact sound. Thus, an

    organism learns to respond to different stimuli in different ways.

    EXTINCTION : disappearance or weakening of a learned response

    following the removal or absence of the unconditioned stimulus [in classical

    conditioning] or [in operant conditioning].

    REINFORCER : any event or object that, when following a response,

    increases the likelihood of that response occurring again.

    SPONTANEOUS RECOVERY : the reappearance of a learned response

    after extinction has occurred.

    HIGHER-ORDER CONDITIONING : occurs when a strong conditioned

    stimulus is pared with a neutral stimulus. A conditioned stimulus plays the

    3/7

    part of the unconditioned stimulus and the neutral stimulus becomes a

    second conditioned stimulus.

    CONDITIONED EMOTIONAL RESPONSES [CER] are emotional

    responses that have become classically conditioned to occur to learnedstimuli.

    BEHAVIOURISM : John Watson said that all behaviour could be

    learned, that all PHOBIAS , or irrational fear responses, could be

    explained in learning. VICARIOUS CONDITIONING : classical conditioning of a reflex

    response learned by watching another persons reaction.

    OTHER CONDITIONED RESPONSES1. CONDITIONED TASTE AVERSION : liquid or food that shouldnt

    taste bad eventually does because of the liquid or food that comes

    after.

    2. BIOLOGICAL PREPAREDNESS : survival mechanism where you

    avoid food by smell or taste that was digested before becoming ill.

    WHY DOES CLASSICAL CONDITIONING WORK ? STIMULUS SUBSTITUTION : activated same place in brain by

    association. COGNITIVE PERSPECTIVE : Conditioned stimulus must provide

    some kind of information about the coming of the unconditioned

    stimulus in order to achieve conditioning.

    OPERANT CONDITIONING is the kind of learning that applies to voluntary

    behaviour.

    EDWARD THORNDIKE : Cat, lever, box; the cat had to learn to push the

    leaver, but Thorndike kept moving it around, and each time the cat would

    learn to look for it in the place where it previously was. LAW OF EFFECT :

    If an action is followed by a pleasurable consequence, it tends to be

    repeated. If its followed by a displeasing consequence, it wont be.

    4/7

    B.F. SKINNER : operant is any behaviour that is voluntary. The heart of

    operant conditioning is the effect of consequences on behaviourlearning

    depends on what happens after the response.

    REINFORCEMENT : any event or stimulus that when following a responseincreases the probability that the response will occur again. It is the key to

    learning in operant conditioning. PRIMARY REINFORCER : naturally reinforcing by meeting a basic

    biological need like hunger or thirst. SECONDARY REINFORCER : reinforcer that reinforces by pairing

    with a primary reinforcer. Personally, that makes no sense

    grammatically, but okay nalang. NEGATIVE AND POSTIVE REINFORCEMENT : it all boils down to

    two kinds of consequencesthings they like and things they dont

    like. Positive is adding, whether reward or punishment; negative is

    subtracting, whether reward or punishment.

    o PUNISHMENT BY APPLICATION : occurs when something

    unpleasant is added to the situation.

    o PUNISHMENT BY REMOVAL : punishment of a response by theremoval of the pleasurable stimulus.

    o PROBLEMS WITH PUNISHMENT

    1. Only suppresses behaviour temporarily.

    2. Punisher may be avoided instead of the punishment.

    3. Lying to avoid punishment.

    4. Punishment creates fear and anxiety, emotional

    responses that dont promote learning.

    5. Hitting encourages aggression. Behaviour by

    modeling.

    o HOW TO MAKE PUNISHMENT EFFECTIVE

    1. Punishment should immediately follow behaviour.

    2. Punishment should be consistent.

    3. Punishment of wrong behaviour should be paired with

    reinforcement of correct behaviour.

    5/7

    SHAPING : reinforcement of simple steps in behaviour that lead to a

    desired, more complex behaviour. EXTINCTION : removal of the reinforcement.

    DISCRIMINATIVE STIMULUS : any stimulus that provides a cue formaking a certain response to obtain reinforcement.

    PARTIAL REINFORCEMENT EFFECT : the tendency for a response

    that is reinforced after some, but not all, correct responses to be

    resistant to extinction. Better for ze long term. CONTINUOUS REINFORCEMENT : the reinforcement of each and

    every correct response. Will learn more quickly but heh, so whut.

    FIXED : the same in eachcase.

    VARIABLE : a differentnumber or interval is

    required in each case.

    INTERVAL

    SCHEDULE : timing

    of the response.

    FIXED INTERVAL

    SCHEDULE OF

    REINFORCEMENT :

    reinforcer is received after

    a certain fixed interval of

    time has passed. Does not

    produce a fast rate of

    responding.

    VARIABLE SCHEDULE

    OF REINFORCEMENT :

    schedule of

    reinforcement in which

    the interval of time that

    must pass before

    reinforcement becomes

    possible is different for

    each trial or event.

    RATIO SCHEDULE :

    certain number of

    responses required

    for reinforcement.

    FIXED RATIO SCHEDULE

    OF REINFORCEMENT :

    the number of responses

    required to receive

    reinforcement is always the

    same number. Fast rate of

    responding.

    VARIABLE SCHEDULE

    OF REINFORCEMENT :

    the number of

    responses changes

    from one trial to the

    next. Rapid change in

    response.

    INSTINCTIVE DRIFT : tendency to revert back to genetically controlled

    patterns.

    6/7

    BEHAVIOUR MODIFICATION : application of operant conditioning to

    change undesirable behaviour into desirable behaviour. TOKEN ECONOMY : use of tokens to modify behaviour.

    APPLIED BEHAVIOUR ANALYSIS [ABA] : modern term for a form ofbehaviour modification that uses the shaping process to mold a

    desired behaviour or response. BIOFEEDBACK : feedback of a persons biological information [such

    as heart rate] to create a modification plan. NEUROFEEDBACK : trying to change brain-wave activity.

    COGNITIVE LEARNING THEORY involves the thoughts, feelings,

    expectations that influence observable behaviour and eventually begin to

    develop a cognitive learning theory to supplement the more traditional

    theories of learning.

    EDWARD TOLMAN : Gestalt psychologist with his rat maze. First rat

    group had reinforcement, second rat group only had reinforcement on the

    tenth day and OMG OMG OMG SHOCKED ZE WORLLLDDDD when they

    solved the maze almost immediately, the third group had no reinforcement

    whatsoever. LATENT LEARNING : information remained latent until there was a

    reason to use it. Rats created a COGNITIVE MAP in their minds.

    WOLFGANG KOHLER : Gestalt psychologist. Sultan the chimp with the

    banana that he could reach with his arm, then with a stick, then with two

    sticks. INSIGHT : the sudden perception of relationships among various parts

    of a problem allowing the solution to come more quickly.

    MARTIN SELIGMAN : harnessed dogs were shocked. When put in a large

    group with a jumpable fence and no harness, they stayed in place. LEARNED HELPLESSNESS : the tendency to fail to act on a situation

    because of a history of failure.

    OBSERVATIONAL LEARNING is learning new behaviour by modeling.

    ALBERT BANDURA AND THE BOBO DOLL : Child played with the toys

    minded by the models. Reinforcement? The kids that were shown a rewardcopied the model beating up the Bobo doll. The ones who were shown a

    punishment did not copy the model until they were given a reward.

    FOUR ELEMENTS

    1. ATTENTION : learner must pay attention. Certain characteristics of

    models can make attention more likely.

    2. MEMORY : learner must retain memory of what was done; in other

    words, remembering steps.3. IMITATION : learner must be capable of imitating.

    4. MOTIVATION : learner must have desire or motivation to perform the

    action.
