PSYC 356 Lecture Notes - Lecture 4: Tuning Fork, Classical Conditioning, Eyeblink Conditioning
Document Summary
Rang a bell just prior to hitting the patellar tendon. The bell became sufficient to elicit knee-jerk reflexes. Dogs increased stomach juices with the sight of food. Before conditioning: unconditioned stimulus = food, unconditioned response = salivation. Before conditioning: neutral stimulus = tuning fork, no conditional response = no salivation. During conditioning: pair neutral stimulus and unconditioned stimulus = tuning fork +food, unconditioned stimulus = salivation. After conditioning: conditioned stimulus = tuning fork, conditioned response = salivation. *it is only a conditioned response if it elicited by conditioned stimulus. Anything elicited by the food is an unconditioned response. Each procedure has face validity with human classical conditioning and probable final cause. Face validity: appears that it will likely happen in humans as well. Infants have limited emotional reactivity but can learn emotional reactions. We can use animals to study fear conditioning.
