Document Summary
In sr (stimulus-response) conditioning, the ns becomes directly associated with the. Ur and comes to elicit the same response as the ur. In the ss (stimulus-stimulus) conditioning, the ns becomes directly associated with the us and comes to elicit a response somehow related to the us. The stimulus-substitution theory proposes that during conditioning the cs and us become so strongly connected neurologically that the cs itself can elicit the response. The major weakness of this theory is that the cr is not always the same as the ur: describe the preparatory-response theory of conditioning. The preparatory-response theory proposes that the purpose of the cr is to prepare an animal for possible presentation of the us: describe the compensatory-response model of conditioning. The compensatory-response theory proposes that sometimes the cr is a compensatory response to the cr. Describe how the rescorla-wagner theory accounts for overshadowing and blocking.
