Historically, researchers have never quite been able to agree as to the role of emotions, if any, when behavior is selected by its consequences. A brief review of findings from several fields suggests that in contingency-shaped behavior, motivating events, often unconscious, seem needed for reinforcement to select behavior. In rule-governed…

If judiciously applied, cognitive terminology can encourage further examination of phenomena in useful ways that may not otherwise be studied. I give examples of 3 phenomena, the study of which have benefitted from a cognitive perspective. For the first, transitive inference behavior, it appears that non-cognitive accounts cannot satisfactorily…

When behavior suggests that the value of a reinforcer depends inversely on the value of the events that precede or follow it, the behavior has been described as a "contrast" effect. Three major forms of contrast have been studied: "incentive contrast," in which a downward (or upward) shift in the magnitude of reinforcement produces a relatively…
