Fundamentals of learning class 34: phase 1 phase 2 transfer test instrumental conditioning pavlovian conditioning present. Pavlovian cs during: performance of the instrumental, tone vs no tone response lever-press --- food tone --- food lever press --- food. Phase 1 can precede or follow phase 2 in a pitt . The two phases of training can also be conducted in different: experimental chambers (often the case). Presentation of the cs+ for shock was then tested when subjects were lever pressing for food: the result was that the pavlovian cs suppressed the instrumental lever-press behavior. Positive emotional state generated by the appetitive cs summates with the appetitive motivation that is involved in pressing the lever to obtain food: amygdala and ventral striatum activity is associated with the pitt in humans. In some cases reward-specific expectancies appear to determine the outcome of pitt. Solid food pellets and a sugar solution were used as uss in a.
