Variations of the Dependent Group Contingency and Effects on Employee Performance

Staff in a human-service setting had to finish daily behavior graphs. The agency set up a dependent group contingency. One staff member was secretly picked. If that person met the graph deadline, the whole team earned a small perk.

The researchers tried two versions. In one, everyone knew who the key person was. In the other, the name stayed hidden. They tracked how many graphs were turned in on time under each rule.

Both rules beat doing nothing. Graph completion rose as soon as either contingency started.

The anonymous version won. When no one knew who the 'mystery' staff member was, more graphs came in complete and on time.

Harris et al. (1978) warned that watching consequences can twist observer notes. Pugliese et al. (2025) sidestep that risk by keeping the designated worker secret, so social pressure on the recorder drops.

Wildemann et al. (1973) showed that just knowing you are being checked can inflate reliability scores. The new study uses the same insight for performance: hide the identity and you get cleaner, higher work output.

Platt et al. (2023) proved that smarter data sheets help staff spot errors. Together the papers push one message: give staff good tools, then remove social cues that tempt them to fudge or rush.

If you run a clinic, school, or day program, you can copy this tomorrow. Pick one employee at random each day. Tell the team: 'If our mystery person finishes notes on time, everyone gets a coffee gift card.' Do not reveal the name. You should see more complete, on-time graphs with almost no extra cost or training.
