Enhancing tolerance to delayed reinforcers: the role of intervening activities.

Clarke et al. (2003) worked with three adults who had intellectual disabilities.

The team wanted to teach them to wait for a bigger reward instead of grabbing a small one right away.

They started by giving the large reward immediately, then slowly added wait time while the adults could play with toys or do puzzles.

All three adults learned to pick the larger, delayed reward once the wait was stretched out.

The toys and puzzles kept them busy, so the delay felt shorter and the big reward stayed tempting.

Capio et al. (2013) later showed you can drop the toys entirely and people still wait.

This extends the 2003 work: use activities at first, then fade them to build independence.

Carlin et al. (2012) got the same self-control gains without any activities.

That looks like a clash, but the 2012 study used snacks versus videos—different kinds of rewards that may need less support.

Logan et al. (2000) ran a similar delay-fade procedure three years earlier with no activities.

The 2003 paper adds the helpful twist: give clients something to do during the wait when impulsivity is high.

You can copy this graduated-delay plus activity package tomorrow. Start with zero-second delay to the big reinforcer, then stretch the wait in small steps while the client colors, plays a game, or completes a short task. Once waiting is steady, try fading the activity just like Capio et al. (2013) to keep the procedure lean and natural.
