To do so, you decide to reinforce writing since he cannot write and tap his pencil at the same time. And behavior analyst to use continuous reinforcement during_____ FR 8 or VR 8), the variable-ratio schedules had produced higher response rates.

Okay, you might be a little confused here. Helping parents understand the distinction not only reduces their resistance to using reinforcement, but also prevents reinforcing the wrong behaviors. American Psychological Association. This behavior again should be functionally equivalent to the challenging behavior. The variable-interval schedule is more resistant to extinction than the fixed-interval schedule as long as the average intervals are similar. Punishment, remember, is the addition or removal of a stimulus that reduces the future occurrence of that behavior.
