Final answer:
Gavin's aversion to tacos after an incident of food poisoning is an example of associative learning, where he has associated tacos with a negative outcome. Associative learning involves a change in behavior due to the formation of an association between a stimulus and a response.
Step-by-step explanation:
Gavin can't eat tacos anymore, ever since he got food poisoning from eating a bad taco. This scenario describes a type of learning known as associative learning, which is when an association is made between a stimulus (in this case, a taco) and a response (avoidance due to the negative experience of food poisoning). Since Gavin has developed a negative response to tacos after this incident, it is clear that his learning is associative. Associative learning is when an individual changes their behavior as a result of developing associations between certain stimuli and outcomes. Non-associative learning, on the other hand, is when a response to a stimulus changes after repeated exposure, without the presence of an associative process.
