Task engagement and escape maintained challenging behavior: differential effects of general and explicit cues when implementing a signaled delay in the delivery of reinforcement.

Reichle et al. (2010) worked with preschoolers with autism who tried to leave hard tasks.

The team used two kinds of delay cues before the children could take a break.

One cue was explicit: "Three more problems, then break." The other was general: a kitchen timer with no number given.

Both cues cut problem behavior and kept kids working.

The explicit cue made children finish the last tasks faster than the timer did.

Older lab studies with pigeons and rats showed that any signaled delay weakens the power of reinforcement. Richards (1981) and Davis et al. (1972) found longer delays slowed responding.

Reichle et al. (2010) agrees, but adds a fix: when you must delay, tell the child exactly what is left.

Later autism studies back this up. van Timmeren et al. (2016) and Majdalany et al. (2016) showed that even six-second delays slow learning. Their results extend Joe’s warning: keep delays short, and if you can’t, make the cue explicit.

You can still use breaks for escape-maintained behavior, but don’t make kids wait in the dark. Count down the final responses out loud or show a short picture list. This small change keeps engagement high while you fade the delay.
