Document Summary
The idea that the effectiveness of a us is determined by how surprising it is forms the basis of a formal. Mathematical model of conditioning proposed by robert rescorla and allan wagner. This has become a reference point for all subsequent learning theories, and its basic assumptions are being. Identified in studies of the neural mechanisms of learning. By definition, an event is surprising if it is different from what. Ex: if you receive a car for your birthday and expected a small gift, you will be very surprised (unexpectedly large. Us) and if you expect a car and receive a box of candy, you will also be surprised (unexpectedly small us). According to the rescorla-wagner model, an unexpectedly large us s the basis for excitatory conditioning and an. Unexpectedly small us (or the absence of the us) is the basis for inhibitory conditioning. Rescorla and wagner assumed that the level of surprise, and hence the effectiveness of a.
