Classical Conditioning Learned Response - learned by paring a neutral stimuli with a natural stimuli (Unconditioned Stimuli) Discovered by Ivan Pavlov while studying digestion Ivan Pavlov ( )
Classical Condition - Pavlov’s Experiment Neutral Stimulus: Bell Rings (neutral stimulus) Gets Dog’s Attention (unrelated to meat) Unconditioned Stimulus Dog Shown Meat (UCS Unconditioned Stimulus) Dog Salaivates (UCR Unconditioned Response) During Conditioning Neutral Stimulus: Bell Rings Unconditioned Stimulus Shown Meat Unconditioned Response Dog Salivates After Conditioning Conditioned Stimulus: Bell Rings (Unconditional Stimulus removed) (no meat shown) Conditioned Response Dog Salivates Before Conditioning
Extinction Extinction of Conditioned Response Un-learning a conditioned response The strength of a conditioned response diminishes if not reinforced. Spontaneous Recovery Immediate reemergence of CR Single paring of CS with CR
Stimulus Generalization Responding similar stimuli as though it were the Conditioned Stimuli
Stimulus Discrimination Ability to differentiate between stimuli
