Stimulus Control and Antecedent Interventions Flashcards

Least-to-most (LTM) prompting involves:

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

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.

Time delay procedures are used primarily to:

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

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.

Errorless learning procedures are designed to:

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

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.

Stimulus fading involves:

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

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.

A response prompt is best defined as:

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

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.

Transfer of stimulus control refers to:

Answer: Shifting control over a response from supplemental prompts to the natural discriminative stimulus

Transfer of stimulus control is the process of shifting behavioral control from training prompts to the natural SD through systematic prompt fading, so the learner responds independently to the natural cue.

Most-to-least (MTL) prompting is most appropriate when:

Answer: The target behavior involves safety risks or the learner has a history of reinforced errors

MTL prompting begins with the most intrusive level of assistance to prevent errors from occurring and is especially appropriate when safety is a concern or when errors have previously been inadvertently reinforced.
