Reward versus cost token systems: an analysis of the effects on students and teacher.

Iwata et al. (1974) · Journal of applied behavior analysis 1974
★ The Verdict

Reward and cost token systems work equally well to cut disruption and double math work in elementary special-ed classes.

✓ Read this if BCBAs running token economies in K-5 special-ed rooms.
✗ Skip if Clinicians who only use function-based plans and avoid token systems.

01Research in Context

01

What this study did

The researchers compared two token systems in a special-ed class. One gave tokens for good work. The other took tokens away for rule breaks.

They flipped the systems back and forth four times. They watched math work, rule breaking, and off-task behavior.

Kids had mixed diagnoses. No one was singled out.

02

What they found

Both systems cut rule breaking and off-task behavior to the same low level. Math output doubled under each system.

Kids did not say they liked one system more than the other.

03

How this fits with other research

McLaughlin et al. (1972) already showed tokens raise test scores. Tracey et al. (1974) now show the same boost happens for daily math work.

Frame et al. (1984) later took the cost idea into the community. Adults with severe ID stopped wandering when tokens could be removed.

Lovitt et al. (1969) let kids set their own goals. They worked even harder than when teachers set rules. That study did not test cost, so the two ideas could be combined.

04

Why it matters

You can pick either reward or cost tokens without losing power. If taking tokens feels harsh, just give them for good work. You will still see less disruption and more math work. Try one system this week. Track the same two behaviors. Swap systems after a few days and see if anything changes.

03Original abstract

The effects of reward and cost token procedures on the social and academic behavior of two groups of elementary special-education students were assessed using a reversal design. Behavioral observations of three target subjects in each group revealed that both procedures were about equally effective in reducing rule violations and off-task behavior. Records kept on the daily arithmetic performance of all subjects showed that output doubled in both groups during the token phases, although accuracy remained unchanged. When students were allowed to choose either contingency, no pattern of preference was established. Small differences were found in teacher behavior: the reward procedure led to an increase in approval comments but cost procedures produced no changes in teacher behavior.
