Using stimulus preference assessments to identify preferred break environments

Castelluccio et al. (2019) asked a simple question: can pictures tell us which break room a child with autism will work for? They showed two kids photos of three break spots: a gym, a computer corner, and a quiet reading nook. Each child tapped the picture they liked best. The team then ran a quick reversal design. Kids earned tokens for math work. They could trade tokens for time in the break spot they picked or a control spot they never chose.

Both kids spent almost all their tokens on the high-preference break. They barely touched the low-preference or control spots. The pictorial assessment predicted real-world reinforcing power. When the preferred break was removed, work dropped. When it came back, work rose again. The photos worked like a crystal ball for break value.

Heinicke et al. (2016) had warned that pictures alone can lie. Some kids picked photos but did not work for the real item. Their fix was to let kids briefly experience the real item first. Castelluccio skipped that step yet still got clean results. The difference may be the domain: Heinicke tested toys and snacks; Castelluccio tested whole break rooms. Rooms may be easier to imagine than novel toys.

Chebli et al. (2016) used a tablet to let kids pick videos. Like Castelluccio, they saw picture choices match later reinforcer use. Both studies show that screen-based or paper-based photos can work when the stimulus is familiar and easy to picture.

Isenhower et al. (2025) broke leisure into parts: social, electronic, movement. They found adults worked best when activities matched their part-profile. Castelluccio kept the break whole. Together the papers suggest: start with a quick whole-room photo test; if results are shaky, drill down to parts like Isenhower did.

You can save session time. Snap three photos of your available break areas. Ask the child to point to the one they want. Run a three-minute reversal to be sure. Once verified, use that room as the reinforcer for the rest of the month. No need to drag out toys or set up fancy stations. A picture really can be worth a thousand trials.
