Occasion setting: Associative learning and cognition in animals.Mechanisms of feature-positive and feature-negative discrimination learning in an appetitive conditioning paradigm.

Mechanisms of feature-positive and feature-negative discrimination learning in an appetitive... Most experiments on occasion setting involve some form of either a feature-positive (FP) or feature-negative (FN) discrimination. The chapter describes some recent research that explored the mechanisms behind the 2 discriminations as they are represented in a commonly used conditioning paradigm in which food is the unconditioned stimulus (US) and the rat's investigation of the food cup provides the measure of conditioned responding. The starting point for the research presented here was the possible connection between FP and FN learning and extinction. In the 2nd part of the chapter, we present some new experiments that were designed to extend the analysis to the FP paradigm. These experiments begin to establish a connection between FP learning and extinction, but, somewhat unexpectedly, they also raise questions about the generality of positive occasion setting and the conditions that are thought to produce it.
