A【0】Collect data and mark that the client selected both items
B【3】Block the client from accessing both items and avoid presenting the same two items together again
C【2】Collect data and mark that since the client did not select 1 item in particular, neither item is preferred
D【1】Block the client from accessing both items, remove the items, and represent the trial with the same items
✓ Correct answer: D. 【1】Block the client from accessing both items, remove the items, and represent the trial with the same itemsIf the client attempts to grab both items, the RBT should block the client from getting both, remove the items, and represent the trial with the same items. Doing so will likely extinguish the client's response of attempting to grab multiple items. Then, once the client selects an item, it is given to the item, which may reinforce the response of choosing one item. If the client continues to attempt to grab both items and this results in problem behaviors, then consult with the client's BCBA, as a different preference assessment may be more fitting.
