Lerman, D. C., & Iwata, B. A. (1996). A methodology for distinguishing between extinction and punishment effects associated with response blocking. Journal of Applied Behavior Analysis, 29, 231-234.

We present one method for distinguishing between extinction and punishment effects. The proportion of responses that produced a consequence (blocking) was varied while hand mouthing was treated in a man diagnosed with profound mental retardation. Response patterns across the schedule changes suggested that the blocking procedure functioned as a punishing event.

DESCRIPTORS: response blocking, sensory extinction, punishment
