The Vanishing Effect in a Token Economy
A residential program for adults with intellectual disabilities runs a token economy in a sheltered workshop. Clients earn tokens for assembling mailers and exchange them Friday for snacks and privileges. Baseline production averages 40 mailers per client per day. The consultant introduces a token for every 10 completed mailers. Production climbs to 65 per day within two weeks and staff praise the plan. In week three, the agency's new payment policy takes effect: clients now receive a small hourly wage regardless of output, and the exchange menu is expanded to include cash-equivalent vouchers. By week five production falls to 38 per day, slightly below baseline, and several clients stop requesting tokens. Staff insist the reinforcement schedule is unchanged and want the consultant to add a response-cost component for low output.
1. Using the concepts of establishing operations, reinforcer efficacy, and competing contingencies, explain the most likely reason production collapsed. What data would you collect before changing anything?

The token itself did not change; what changed was the motivating operation and the competing contingency surrounding it. The new hourly wage delivers noncontingent reinforcement, which weakens the establishing operation for tokens by satiating the reinforcers the tokens purchase. Expanding the menu to cash-equivalent vouchers may also have altered the relative value of tokens versus wages, so the token's conditioned reinforcing effectiveness dropped even though the schedule stayed identical. Production below baseline suggests the wage is now functioning as reinforcement for attendance rather than output, and possibly that responding is being extinguished because output no longer correlates with the payoff clients care about.
Before adding punishment, collect: (1) a concurrent probe of token exchange rates and which items clients actually choose, (2) session-by-session production per client, not just the group mean, to see whether the drop is uniform or driven by a few clients, (3) staff-implemented token delivery integrity checks, since "the schedule is unchanged" is an assertion, not a measurement, and (4) a brief preference assessment post-policy change. Adding response cost now would punish behavior whose reinforcer has already been devalued, which risks countercontrol and aggression without addressing the actual contingency.
2. Staff propose response cost for low output. Evaluate this proposal against the least-restrictive-treatment and punishment-side-effects literature, and describe a better alternative.

Response cost is a punishment procedure. Before adopting it, the team should be able to show that reinforcement-based options were tried and failed, that the target behavior is dangerous or seriously impairing, and that the procedure is the least restrictive effective option. Here the collapse is better explained by a devalued reinforcer and a competing wage contingency, so punishment would be treating a symptom while the controlling contingency remains intact.
Known side effects to weigh: emotional responding and aggression, escape and avoidance of staff and the workshop, suppression of untargeted appropriate behavior, and imitation of coercive control in a setting where clients have limited power to leave. In an adult service context, response cost tied to wages may also raise consent and dignity concerns.
A better alternative is to restore the contingency between output and a reinforcer clients actually value. Options include arranging a pay-for-performance component within the new wage structure (so the wage and tokens are not competing), re-running a preference assessment and rebuilding the exchange menu around high-preference items, thinning the token schedule gradually from FR10 toward a more sustainable ratio, and adding social praise paired with tokens. Evaluate with a reversal or multiple-baseline design across clients, and monitor both production and any negative affect so gains are not purchased with distress.
