What is the difference between appetitive and aversive conditioning?
In classical conditioning, an initially neutral stimulus (conditioned stimulus, CS) becomes associated with a biologically salient event (unconditioned stimulus, US), which might be pain (aversive conditioning) or food (appetitive conditioning).
What is an example of appetitive conditioning?
