What distinguishes one differential reinforcement procedure from another?
Differential reinforcement arranges reinforcement to strengthen a useful behavior, reduce another behavior, or both; procedures differ in what earns reinforcement.
What earns reinforcement in DRA?
DRA reinforces a specified appropriate alternative to the target behavior. The alternative may serve the same need without being physically incompatible with the target behavior.
What earns reinforcement in DRI?
DRI reinforces a behavior that cannot physically occur at the same time as the target behavior, such as keeping hands on a desk instead of grabbing materials.
How is DRI related to DRA?
DRI is a specific type of DRA: it reinforces an alternative behavior that is physically incompatible with the target behavior.
What earns reinforcement in DRO?
DRO reinforces the absence of the defined target behavior during a specified interval or at a check-in; it does not specify a replacement behavior.
What earns reinforcement in DRL?
DRL reinforces a behavior when its rate meets a preset lower-rate criterion. The behavior is still permitted; the goal is not necessarily to eliminate it.
When does whole-interval DRO deliver reinforcement?
Whole-interval DRO delivers reinforcement only if the target behavior did not occur at any point during the interval.
How does momentary DRO assess the target behavior?
Momentary DRO checks whether the target behavior is absent at the end of the interval and delivers reinforcement if it is.
What is continuous reinforcement (FR 1)?
Continuous reinforcement, or FR 1, reinforces every occurrence of the selected response. It can be useful when teaching a new response.
What is intermittent reinforcement, and when might its schedule be thinned?
Intermittent reinforcement delivers reinforcement according to a response-count or time-based rule. Once a response is established, its schedule may be gradually thinned while monitoring stability.
What is the criterion in spaced-responding DRL?
Spaced-responding DRL reinforces a response only after a specified minimum time has passed since the previous response.
What is the criterion in interval DRL?
Interval DRL reinforces if the response count stays at or below a set criterion within each interval.
