Animals can learn to prefer a location where they received a reward (like food or mating opportunities) after a single exposure (one-trial learning).

“So called condition place preference you can take an animal, put it into an arena, feed it or reward it some how at one location in that arena. So you can give a hungry rat or mouse food at one particular location, take the animal out, come back the next day. No food is introduced, but it will go back to the location where it received the food.”
