Does preference rank predict substitution for the reinforcer for problem behavior? a behavioral economic analysis

The team ran a single-case experiment with four children who had problem behavior.

First they did a standard preference assessment to rank six toys or snacks.

Then they made each kid work for the items under easy and hard tasks while measuring how much the kids still wanted the reward.

The top-ranked item did not always stay the best when work got harder.

For two kids the favorite toy lost power; for two it stayed strong.

No clear rule linked first-place rank to later reinforcer strength.

Older studies like Hamilton et al. (1978) and Howlin et al. (2006) showed that simple preference rankings can predict choices in calm tests.

Frank-Crawford adds a twist: when the response cost rises, those calm-test rankings may break down.

This looks like a clash, but it isn’t — the early papers never tested the items under tough work demands.

Moya et al. (2022) later found that only half of component studies isolate one key piece; our result fits that messy picture by showing that reinforcer value itself can be a moving part.

Before treatment, probe the item again while the client is doing the actual task you will ask for.

If the “favorite” breaks under load, pick the second or third item, or add a new one.

This quick check can save you from a failed reinforcement plan and extra problem behavior next week.
