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

A response has been punished and is less likely to occur

Answer

A response has been placed on extinction

Answer

Reinforcement is delivered on a fixed-ratio schedule

Question 2

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

Accepted Answer

S-delta (SΔ)

Answer

Discriminative stimulus (SD)

Answer

Conditioned reinforcer

Answer

Unconditioned stimulus

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

Delivering reinforcement only when the target behavior occurs at a high rate

Answer

Withholding reinforcement to reduce problem behavior through extinction

Answer

Pairing a neutral stimulus with an established reinforcer to create a conditioned 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

Presenting the most challenging task first to build frustration tolerance

Answer

Reinforcing only the most complex version of a target behavior from the start

Answer

Using extinction for all low-probability behaviors until compliance increases

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

A behavior occurs only in the presence of the exact stimulus used during training

Answer

A reinforcer loses its effectiveness due to repeated delivery

Answer

Multiple behaviors are brought under the control of a single discriminative stimulus

Question 6

Which type of prompt involves the trainer physically guiding the learner through the correct response?

Accepted Answer

Physical prompt

Answer

Gestural prompt

Answer

Model prompt

Answer

Positional prompt

Question 7

Stimulus discrimination training establishes stimulus control by:

Accepted Answer

Reinforcing a response in the presence of the SD and placing it on extinction in the presence of the SΔ

Answer

Reinforcing a response in all stimulus conditions to maximize generalization

Answer

Using punishment to suppress responses that occur during SΔ presentations

Answer

Delivering reinforcement at random intervals regardless of which stimulus is present
