Document Summary

Some problems with the rescorla-wagner model: exclusive focus on the surprisingness of the us. Nicholas mackintosh model - the mackintosh model. John pearce & geoffrey hall - the pearce-hall model. It is important to consider how the salience of the cs (a) changes during conditioning. ***must consider how the salience, value, importance of the cs also changes during conditioning not only the us: the conclusion that extinction destroys the original learning. Spontaneous recovery: the reappearance of a cr to a cs after a period of time following the last extinction trial (pavlov) Spontaneous recovered response to the cs after extinction. Renewal: the reappearance of a cr to a cs due to return to the training environment, instead of the environment used during extinction. Acquisition (a) and extinction (b) happen in different contexts, after extinction you do a test in context a and context b, in context a we get a full blown response.
