S-R versus S-S Learning= I. S-R Learning= conditioning establishes a new stimulus-response (S-R connection) b/w the CS and the CR II. S-S Learning= subjects learn a new stimulus-stimulus (S-S connection) b/w the CS and the US - subjects respond to the CS not b/c it elicits a CR directly but b/c the CS activates a representation of the US A. US Devaluation= the way to decide b/w S-R and S-S learning - Holland and Rescorla (1975)= 1. Conditioned 2 grps of mildly food-deprived rats by repeatedly pairing a tone w/ pellets of food (establish association b/w the tone CS and food US, and to get the rats to form a representation of the food US) -CS=tone -US=food 2. US devaluation. The experimental grp received a treatment designed to make the US less valuable to them -experimenters gave the subjects sufficient free food to satisfy their hunger completely (this reduced the value of food= devalues the US representation) -the control grp did not change; US representation was still apparent 3. Both grps received a series of test trials w/ the tone-conditioned stimulus -the experimental grp showed significantly less conditioned responding than the control grp= S-S learning! -if it was a S-R connection, the CR would have been elicited whenever the CS
