Do children prefer contingencies? An evaluation of the efficacy of and preference for contingent versus noncontingent social reinforcement during play.

Researchers watched eight preschoolers during free play.

Kids got teacher praise two ways: only after nice play (contingent) or every 30 seconds no matter what (non-contingent).

The schedule swapped every few minutes so each child felt both setups in one morning.

When children could pick the next game, seven of eight chose the table where praise was earned, not the free-praise table.

They kept playing longer and smiled more when praise matched their actions.

Protopopova et al. (2020) saw the same thing with therapy dogs: kids with autism worked harder when dog time followed correct answers.

Harrison et al. (1975) and Winett et al. (1972) already showed contingent tokens or praise beat non-contingent versions for compliance and handwriting.

Galizio et al. (2020) stretched the idea further, showing kids with autism can even learn to prefer new play patterns when contingencies are clear.

Morris et al. (2024) warn that many studies still pick edible or generic praise first; this 2009 lab reminds us to test what children actually want.

You can skip the guesswork. Let the client sample both schedules for five minutes, then ask, "Which table do you want?" If the child picks the contingent side, you have instant buy-in and a built-in reinforcer that costs nothing. Try it during play, circle time, or chores next week.
