In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

Motivating operations (MO) play an important role in learning and performance. According to the behavior analytic conceptualization, MOs alter the probability of responses that lead to relevant reinforcers and alter the reinforcing “value” of those reinforcers (e.g., Michael, 1982, 1993). Recent research suggests that one way in which MOs influence stimulus control is by influencing the control of behavior by discriminative stimuli. Interestingly, in studies with nonhumans, such an effect is commonly observed when lights and tones are used as discriminative stimuli, but not when drugs are used. Procedural differences across studies involving the species studied, the measurement system used …
