Document Summary
S: neutral stimulus (cs) that becomes predictor of s* Pseudo-conditioning increased responding to the cs that might occur because of mere exposure to the us: conditioning did not actually supply the cs with predictive value, just appears this way. Sensitization to the cs response isn"t due to predictive value of cs, just due to the new value the cs now has due to repeated exposure. Cs cs-centre" us-centre" response-centre" . Pseudo-conditioning increased responding to the cs that might occur because of mere exposure to the us sensitization to the cs s-r learning 1) post-conditioning devaluation (us devaluation) *cs stops producing a cr because the us that it was predictive of is no longer valuable. Rescorla (1973): light (cs) conditioned with a loud noise (us) Holland and straub (1979): noise (cs) conditioned with food (us) No fear b/c fear- inducing us (noise) has been devalued. *both indicate s-s associative learning one stimulus becomes a learned predictor of the other: cs-cs associations:
