2  Russian physiologist, psychologist, & physician.  Research in digestion.

3  Noticed the dog not only salivated when tasting food but also…  at the sight of food.  at the sight of the food dish.  at the sight of the person delivering the food.  at the sound of that person’s footsteps.

4  Conducted experiments using classical conditioning.  A type of associative learning in which one learns to link two or more stimuli and anticipate events.

5 Food Bell Salivation +

6 Food (US) Salivation (UR)  Unconditioned Stimulus (US)  a stimulus that naturally and automatically triggers a response.  Unconditioned Response (UR)  the unlearned, naturally occurring response to the unconditioned stimulus.

7 Food (US) Bell (NS) Salivation (UR)  Neutral Stimulus (NS)  an irrelevant stimulus that does not trigger a natural response.  becomes the conditioned stimulus. +

8 Bell (CS) Salivation (CR)  Conditioned Stimulus (CS)  an originally irrelevant stimulus that, after association with an unconditioned stimulus, comes to trigger a conditioned response.  Conditioned Response (CR)  the learned response to a previously neutral (but now conditioned) stimulus.
