PSYCH 10 Lecture Notes - Lecture 4: Graham Cracker, Vending Machine, Observational Learning
Document Summary
Salivation was (eventually) triggered by what should have been neutral stimuli like. Seeing the food, seeing the dish, seeing the person who brought food. Before conditioning: food (unconditioned stimulus) --> dog salivates. During: bell (neutral stimulus) + food --> dog salivates. Ex: if bell keeps ringing but no food, salivation eventually decreases: generalization vs. discrimination, generalization--once a response has been conditioned, similar stimuli can elicit the same response. Discrimination--ability to distinguish between similar but distinct stimuli. Ex: if dog shows less salivation to a diff bell tone. The rat was originally a neutral stimulus, but after combined with the hammer (unconditioned stimulus) --> unconditioned response: fear. Neutral stimulus rat becomes conditioned stimulus --> conditioned response: fear. Little peter: graham cracker and fear of rabbit. Give cracker and put rabbit in room, eventually conditioned to not fear it. Classical conditioning --> reactive behaviors: operant conditioning --> voluntary behaviors, operant behavior has some impact on the environment.
