Classical ConditioningClassical Conditioning

Classical Conditioning:Classical Conditioning: Ivan Pavlov Ivan Pavlov (Behavioral Psychologist)(Behavioral Psychologist) Example of learningExample of learning A learning procedure in which associations are A learning procedure in which associations are

made between a made between a natural stimulusnatural stimulus and a and a neutral stimulusneutral stimulus

E.g. Lightning E.g. Lightning (natural stimulus)(natural stimulus) elicits elicits “rain”“rain”

E.g. Lightning E.g. Lightning (natural stimulus)(natural stimulus) and and umbrellas umbrellas (neutral stimulus)(neutral stimulus) elicit “rain” elicit “rain”
