Garcia Effect
The Garcia effect is an example of classical
conditioning in everyday life. The Garcia Effect
(conditioned taste aversion) is an aversion or distaste for a particular taste
or smell that was associated with a negative reaction (such as nausea or
vomiting).
This effect was
discovered by John Garcia while he was studying effects of radiation on mice.
He noticed that rats would avoid a new food when it was initially presented
around the time of radiation exposure, which causes nausea and a general
feeling of sickness. The Garcia effect occurs in patients undergoing treatment
for cancer who are exposed to radiation as treatment. It can also happen in
humans when a bad reaction occurs as a result of ingesting a particular food or
drink, either from food poisoning or overindulgence.
