Environmental arrangement as an antecedent strategy in early intervention often involves:
Answer: Structuring the environment to create opportunities for communication and engagement
Environmental arrangement sets up physical space and materials to naturally evoke desired behaviors like communication without relying on artificial prompts.
A most-to-least (MTL) prompting strategy is considered antecedent-based because:
Answer: Prompts are provided before responses to prevent errors
MTL prompting provides support before the learner responds, functioning as an antecedent that guides correct behavior and prevents errors.
The primary mechanism by which a high-p sequence increases compliance with low-p requests involves:
Answer: Building behavioral momentum and increasing reinforcement density
The high-p sequence increases behavioral momentum and makes compliance more reinforcement-dense before the low-p request, increasing the probability of compliance.
Which scenario best distinguishes NCR from differential reinforcement of other behavior (DRO)?
Answer: NCR delivers reinforcement on a time-based schedule; DRO delivers reinforcement contingent on the absence of problem behavior
NCR is delivered independent of behavior on a time schedule, while DRO requires that problem behavior be absent during an interval before reinforcement is delivered.
Which of the following is classified as an antecedent-based intervention?
Answer: Noncontingent reinforcement delivered on a fixed-time schedule
NCR on a time-based schedule is a prototypical antecedent intervention because it targets motivating operations before problem behavior occurs rather than responding to it.
Task modification as an antecedent strategy may include all of the following EXCEPT:
Answer: Providing extinction following problem behavior during tasks
Extinction is a consequence-based procedure applied after problem behavior, not a modification of antecedent task characteristics.
When selecting an antecedent intervention for a learner whose aggression is maintained by attention, the most function-based antecedent choice would be:
Answer: Providing dense noncontingent attention before and during sessions
For attention-maintained aggression, providing noncontingent attention (NCR-attention) abolishes the EO for aggression by ensuring the learner's attention need is already met.
