ANSWER KEY:


1. Correct answer is C.

Interventions based on training, task clarification, or prompting may include providing BST, clarifying the tasks, or modifying the environment to provide prompts to the learner.


2. Correct answer is A.

All of the answers provided are recommended components of a changing criterion design besides changing the criterion every session. Typically, the changes occur after at least 3 sessions/data points

(Cooper, Heron, & Heward, 2019, p. 209).


3. Correct answer is D.

The aversive stimulus of being told she is not allowed to go to recess was a warning stimulus (being associated with not participating in a preferred stimulus). This motivating operation was the stimulus event likely being escaped in this contingency. (Cooper, Heron, & Heward, 2019, p. 386)


4. Correct answer is B.

In a DRO procedure the reinforcer is delivered contingent on the non-occurrence of the target behavior. This has potential to reinforce any behavior that could be going on when the reinforcer is delivered (Not necessarily only appropriate behaviors such as participating in class). (Cooper, Heron, & Heward, 2019, p. 600)


5. Correct answer is D.

Based on the ABC data, it appears that prompting a task is reinforcing the behavior. The antecedents suggest an attention function. Some interventions that could address this include ignoring shouting (extinction) and providing frequent attention throughout the day, potentially in the form of task requests (NCR). (Cooper, Heron, & Heward, 2019, p. 635)
