Document Summary
S-r model (stimulus-response association): ns is directly associated with ur. S-s model (stimulus-stimulus association): ns is directly associated with us stimulus-substitution theory. Pavlov 1927 - cs comes to act as a substitute for us. Implies that cr will be very similar to ur, which is sometimes true, but not always the case preparatory response theory. Cr prepares individual for presentation of us. Freezing in response to light prepares rat for shock. Fear at sight of a dog prepares to you flee or fight. Salivation before food is presented prepares you to eat compensatory-response model. Cr is the opposite of the ur. Often occurs with drug reactions (e. g. , heroin) Environmental cues : heroin drop in blood pressure. In normal conditioning, we would expect environmental cues drop in blood pressure. Environmental cues increased blood pressure compensatory responses help maintain homeostasis. If they occur before the us is presented, they can better moderate the effects of the us drug addiction.
