A discriminative stimulus (SD) is best defined as a stimulus in the presence of which:
Answer: A response has been reinforced and is therefore more likely to occur
An SD is a stimulus in whose presence a specific response has been reinforced, increasing the probability of that response occurring.
Which term describes a stimulus in the presence of which a response has NOT been reinforced?
Answer: S-delta (SΔ)
The S-delta (SΔ) is a stimulus in whose presence a response has not been reinforced, signaling that reinforcement is not currently available.
Noncontingent reinforcement (NCR) as an antecedent intervention is best described as:
Answer: Delivering reinforcement on a time-based schedule independent of any specific behavior
NCR delivers a reinforcer on a fixed- or variable-time schedule regardless of behavior, serving as an antecedent strategy that reduces the motivation for problem behavior maintained by that reinforcer.
The high-probability (high-p) request sequence antecedent intervention involves:
Answer: Delivering a series of easy, well-established requests immediately before a low-probability request
The high-p sequence presents several requests the learner reliably complies with immediately before a demand they typically refuse, using behavioral momentum to increase compliance with the low-p request.
Stimulus generalization occurs when:
Answer: A behavior trained under one stimulus condition also occurs in the presence of similar untrained stimuli
Stimulus generalization occurs when a response trained in the presence of one stimulus also occurs in the presence of other stimuli that share similar properties, without additional direct training.
Which type of prompt involves the trainer physically guiding the learner through the correct response?
Answer: Physical prompt
A physical prompt involves the trainer directly guiding the learner's body through the correct response and is considered the most intrusive type of response prompt.
Stimulus discrimination training establishes stimulus control by:
Answer: Reinforcing a response in the presence of the SD and placing it on extinction in the presence of the SΔ
Stimulus discrimination training differentially reinforces a response when the SD is present while extinguishing the same response when the SΔ is present, establishing precise stimulus control.
