Quizplus · Accepted Answer

Taste aversions can occur even if there is a delay between the CS (e.g. food) and the US (e.g. illness). This is thought to be because the taste of the food serves as a powerful CS that can become associated with the illness that follows, even if the delay is several hours. As a result, a person may develop an aversion to the taste of the food even if they didn't experience any nausea or illness until hours after eating it.
