Document Summary
Preparedness: innate tendency for an organism to more easily learn certain types of behaviours or to associate certain types of events with each other. Taste aversion conditioning: a form of classical conditioning in which a food item that has been paired with gastrointestinal illness becomes a conditioned and aversive stimulus. Experiment: rats are first given some type of preferred for or drink to ingest (ie. saccharine flavoured water), then the rat was made to feel sick by injection or radiation. After the rat recovers from illness, they are more likely to drink normal water over the previously preferred flavoured water. Sweet water (ns): x-ray irradiation (us) nausea (ur) Stimulus generalization: occurs when the food items that taste similar to the aversive item are also perceived as aversive. Taste aversion can also be extinguished if the food is continuously ingested without further illness.
