Consider the following two belief-ascriptions: “Mary believes that 1 + 1 = 2” and “Mary believes that 2756 + 488 = 3244.” Even though both propositions (“1 + 1 = 2” and “2756...

Operant behavior is behavior "controlled" by its consequences. In practice, operant conditioning is the study of reversible behavior maintained by reinforcement schedules. We review empirical studies and theoretical approaches to two large classes of operant behavior: interval timing and choice. We discuss cognitive versus behavioral approaches to timing, the "gap" experiment and its implicatio...

Classical conditioning experiments are reviewed in which the dependent variables are subjective responses, typically involving the evaluation of stimulus materials. These experiments suggest that classical conditioning produces a positive or negative change in the evaluation of previously neutral stimuli. We re-interpret these studies as well as presenting data of our own to support the view th...
