BCABA Stimulus Control and Antecedent Interventions 2

Question 1

Least-to-most (LTM) prompting involves:

Accepted Answer

Beginning with the least intrusive prompt and increasing intrusiveness only if the learner does not respond correctly

Answer

LTM prompting starts with the least assistance needed and escalates prompt intrusiveness only when the learner does not respond independently, promoting independent responding from the beginning.

Question 2

Time delay procedures are used primarily to:

Accepted Answer

Transfer stimulus control from prompts to natural cues by inserting a pause between the SD and the prompt

Answer

Time delay inserts an interval between the SD and the prompt, giving the learner an opportunity to respond independently, thereby gradually transferring stimulus control from the prompt to the natural cue.

Question 3

Errorless learning procedures are designed to:

Accepted Answer

Minimize errors during skill acquisition by using intrusive prompts from the outset of training

Answer

Errorless learning uses intensive prompting at the start of training to prevent incorrect responses, then systematically fades prompts to transfer stimulus control while keeping error rates near zero.

Question 4

Stimulus fading involves:

Accepted Answer

Gradually altering the physical dimensions of the antecedent stimulus to transfer stimulus control to the natural cue

Answer

Stimulus fading systematically changes the physical characteristics of the discriminative stimulus itself (e.g., size, color, intensity) to shift control from an exaggerated cue to the natural, unmodified stimulus.

Question 5

A response prompt is best defined as:

Accepted Answer

A supplemental stimulus added to the training context that directly cues the desired response

Answer

A response prompt is an added stimulus (e.g., model, gesture, physical guidance) that directly increases the probability of the correct response, acting on the learner's behavior rather than on the target discriminative stimulus.
