Quizplus · Accepted Answer

Vicky's development of a taste aversion after eating contaminated carrots is an example of classical conditioning. The nausea-producing toxins act as the unconditioned stimulus (UCS), which naturally produces the unconditioned response (UCR) of nausea. Before the contamination, carrots were a neutral stimulus (NS) that did not produce any physiological response. However, after the pairing of the contaminated carrots with nausea, the carrots became a conditioned stimulus (CS) that produced a conditioned response (CR) of aversion or disgust.
