Final answer:
Taste aversion is a type of conditioning where an individual develops an aversion to a specific food after experiencing illness or nausea after consuming that food.
Step-by-step explanation:
Taste aversion is a type of conditioning in which an interval of several hours may pass between the conditioned stimulus (something ingested) and the unconditioned stimulus (nausea or illness). It occurs when an individual develops an aversion to a specific food after experiencing illness or nausea after consuming that food. In the case of Paul, he became sick after eating chili dogs, so he no longer likes chili dogs. This is an example of taste aversion.
