This article reviews recent research on the extinction of instrumental (or operant)
conditioning from the perspective that it is an example of a general retroactive interference …

An occasion setter is a stimulus that modulates the ability of another stimulus to control
behavior. A rich history of experimental investigation has identified several important …

Five experiments tested implications of the idea that instrumental (operant) extinction
involves learning to inhibit the learned response. All experiments used a discriminated …

Extinction is one of the best-known phenomena in all of learning theory. In Pavlovian
learning, extinction occurs when the conditioned stimulus (CS) that has been associated …

We present a new mathematical formulation of associative learning focused on non-human
animals, which we call A-learning. Building on current animal learning theory and machine …

Recent studies suggest a significant role for context in controlling the acquisition and
extinction of simple operant responding. The present experiments examined the contextual …

Rationale Anticipation is a critical antecedent to drug use, in which the prospect of imminent
drug availability can potently motivate instrumental actions directed to procure it. Models that …

Dogs trained to search for contraband perform a chain of behavior in which they first search
for a target and then make a separate response that indicates to the trainer that they have …

This chapter reviews recent research from the author's laboratory on habit and goal-direction
in instrumental learning and then considers some of its implications for a general view of …

Operant behavior often takes place in a sequence, or chain, of linked responses that lead to
a reinforcer. We have recently studied rats performing a discriminated heterogeneous …
