Abstract:
Differential reinforcement of other behavior (DRO) is a commonly used technique for behavior reduction, yet there has been little to no emphasis on the possible strengthening effects on other behavior. We included 2 responses (target and other) across 3 treatment schedules (DRO, extinction, and fixed time [FT]) in a human-operant procedure to determine the extent to which reinforcer presentation at the completion of the DRO interval could strengthen other responding. A computer program arranged for unsignaled changes in contingencies to a target response and never provided reinforcers for the other response. All 13 college-student participants exhibited more other responses than target responses during at least 1 exposure to DRO. Although there was a slight increase in other behavior during extinction, overall rates of other responding were never higher than that of the target response. Furthermore, 7 of 13 participants never emitted the other response during the FT condition. The findings provide some support for the response-strengthening effects of DRO.

Generalization, Discrimination, and Extinction
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...
