Conditioned taste aversion (CTA) is a form of associative learning in which an animal learns to avoid and reject a food after the taste or flavor of the food is paired with a toxic consequence. For example, an animal encounters a new food with a distinctive (but not necessarily aversive) taste. The animal eats the food, but subsequently gets sick. The animal will associate the taste with the sickness, so that the next time it encounters the food, it will avoid it, or eat less of it. This form of learning has obvious advantages for survival, and animals are extremely good at learning what foods are safe to eat, and what foods are toxic and should be avoided. | Conditioned taste aversion (CTA) is a form of associative learning in which an animal learns to avoid and reject a food after the taste or flavor of the food is paired with a toxic consequence.
