Displacement

In preference assessments, a pattern in which one kind of item, often food, is chosen so consistently that other items rank lower than they would on their own. Lower-ranked items may still work as reinforcers.

Example from a session

Crackers and candy fill the top spots, and toys only come up after all the edibles are gone.
