BCABA Stimulus Control and Antecedent Interventions

Question 1

A discriminative stimulus (SD) is best defined as a stimulus in the presence of which:

Accepted Answer

A response has been reinforced and is therefore more likely to occur

Answer

An SD is a stimulus in whose presence a specific response has been reinforced, increasing the probability of that response occurring.

Question 2

Which term describes a stimulus in the presence of which a response has NOT been reinforced?

Accepted Answer

S-delta (SΔ)

Answer

The S-delta (SΔ) is a stimulus in whose presence a response has not been reinforced, signaling that reinforcement is not currently available.

Question 3

Noncontingent reinforcement (NCR) as an antecedent intervention is best described as:

Accepted Answer

Delivering reinforcement on a time-based schedule independent of any specific behavior

Answer

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.

Question 4

The high-probability (high-p) request sequence antecedent intervention involves:

Accepted Answer

Delivering a series of easy, well-established requests immediately before a low-probability request

Answer

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.

Question 5

Stimulus generalization occurs when:

Accepted Answer

A behavior trained under one stimulus condition also occurs in the presence of similar untrained stimuli

Answer

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.
