Question

Quizplus · Accepted Answer

The taste of the eggs initially had no significance to the mongooses, so it cannot be an unconditioned stimulus or response. However, after being paired with the illness caused by carboachol, the taste of the eggs became a stimulus that triggered the aversion in the mongooses. Thus, it is a conditioned stimulus.
