An arrangement such that one event is arranged or programmed to follow another. For example, a classical contingency is where a neutral stimulus is arranged to occur just before an unconditional stimulus. In an instrumental contingency, it is arranged that an event (e.g. food presentation) occurs immediately after a response by the animal (e.g. lever-pressing).
An animal is said to be contraprepared to learn something when it has a bias against learning it. For example, whereas rats are easily able to learn an association between a taste and gastrointestinal upset, it is difficult to teach them an association between a sound and gastrointestinal upset.See also prepared.
