Differential reinforcement of alternative behaviour (DRA)
A procedure for decreasing a problem behaviour by reinforcing a functionally equivalent alternative behaviour to replace the problem behaviour
Differential reinforcement of communication (DRC)
A type of DRA procedure in which a communication response is reinforced to replace the problem behaviour. Also called functional communication training.
Differential reinforcement of an incompatible behaviour (DRI)
A type of DRA procedure in which a physically incompatible behaviour is reinforced to replace the problem behaviour
Differential reinforcement of low rates of responding (DRL)
A procedure in which a lower rate of a particular behaviour is reinforced to decrease the rate of the behaviour. Used when the goal is to decrease but not necessarily to eliminate a target behaviour
Differential reinforcement of other behaviour (DRO)
A procedure in which the reinforcer is delivered after intervals of time in which the problem behaviour does not occur. DRO involves reinforcing the absence of the problem behaviour
Full-session DRL
A differential reinforcement of low rates of responding (DRL) procedure in which the reinforcer is delivered if fewer than a specified number of responses occurs in a specific period (the session). It is used to decrease the rate of a behaviour
Function communication training is also called?
Differential reinforcement of communication
Interresponse time (IRT)
The time between the occurrence of consecutive responses
Interval DRL
A type of differential reinforcement of low rates of responding (DRL) procedure that involves dividing a session into consecutive intervals or time and providing the reinforcer if no more than one response occurred in each interval.
Momentary DRO
A type of differential reinforcement of other behaviour (DRO) procedure in which the reinforcer is delivered if the person is refraining from the problem behaviour at the end of the DRO interval. The problem behaviour does not have to be absent throughout the entire interval for the reinforcer to be delivered. Momentary DRO typically is not effective unless it follows the use of a whole-interval DRO procedure
Multiple stimulus assessment
An array of potential reinforcers is presented to the individual and the researcher records which potential reinforcer the individual approaches or chooses first. Then that stimulus is removed to see what the next stimulus the individual approaches until they are all gone. The stimuli are then presented again to see the order they are taken in to determine which reinforcers are the strongest.
Multiple stimulus without replacement (MSWO)
Very similar to multiple stimulus assessment
Paired stimulus assessment
Two potential reinforcers (from an array of potential reinforcers) are presented to the individual and the researcher records which stimulus the individual approaches. Each stimulus is presented with every other stimulus multiple times and the researcher calculates the percentage of times that the individual approaches each stimulus, indicating which stimuli are likely to be reinforcers.
Preference assessment
A process of identifying reinforcers for an individual that involves presenting potential reinforcers and measuring whether the individual approaches, manipulates, or consumes the item. Preference assessments can be conducted in at least three different ways; single stimulus assessment, paired stimulus assessment, and multiple stimulus assessment.
Reinforcer assessment
A process in which an item from a preference assessment is delivered contingent on a behaviour to see if the behaviour increases. If the behaviour increases, the item functions as a reinforcer.
Spaced-responding DRL
A type of differential reinforcement of low rates of responding (DRL) procedure in which the reinforcer is delivered when responses are separated by a specific time interval. If a response occurs before the interval has ended, the reinforcer is not delivered and the interval is reset. The interval between responses is called the interresponse time.
Stereotypic behaviour
Repetitive behaviours that do not serve any social function for the individual. They are often called self-stimulatory behaviours because they function to produce some form of sensory stimulation for the individual.
Single stimulus assessment
Each potential reinforcer (from an array of potential reinforcers) is presented (i.e. put on a table in front of the child), one at a time, to see whether the individual approaches the stimulus or not. After each stimulus is presented numerous times, the researcher calculates the percentage of times that the individual approached each stimulus to indicate which stimuli are likely to be reinforcers.
Whole-interval DRO
A type of differential reinforcement of other behaviour (DRO) procedure in which the problem behaviour must be absent throughout the entire interval of time for the reinforcer to be delivered. Most DRO procedures involve whole-interval DRO
