Reinforcer assessment for children with developmental disabilities and visual impairments.

The team worked with children who had both developmental delays and visual impairments.

They compared two ways to find reinforcers. One way let kids pick between items right before work. The other way only asked adults what kids liked.

The goal was to see which method picked items that actually worked as rewards.

Choice-based testing picked better reinforcers than adult ranking.

Items chosen by the kids themselves kept them working longer and harder.

Wanchisen et al. (1989) got the same result six years earlier with preschoolers who had autism. Choice beat simple preference lists there too.

Heinicke et al. (2016) later showed pictures can work, but only if you let kids touch or play with the picture first. That step turns the picture into a real choice, not just a guess.

Kittler et al. (2004) said mix caregiver interviews with direct tests. This study shows the direct test should be a choice, not just watching what a child reaches for.

If your client cannot see well, do not rely on parent report alone. Set out two or three tangible items. Let the child pick right before the task. Use the picked item as the reinforcer. This five-minute step saves you from using rewards that do not work.
