Stimulus fading as treatment for obscenity in a brain-injured adult.

The team worked with one adult who had a brain injury. After the injury, the man shouted obscene words whenever staff gave him a task.

First, the staff stopped giving any demands. The swearing dropped to zero. Then they slowly brought the tasks back, a little more each day. This slow return is called stimulus fading.

Obscene language stayed low even as work returned to full level. The man kept doing the tasks without extra rewards or punishment.

Fading the demands was enough. No extinction, no time-out, no token board were needed.

Jackson et al. (2026) later used the same fading logic on therapy rooms instead of tasks. They faded wall colors and props back in after DRA and cut renewal in half. Together, the two studies show fading works for both tasks and places.

Dowdy et al. (2020) and Boyle et al. (2023) also skipped extinction. They used DR and FCT to cut problem behavior in kids with autism. Dougherty et al. (1994) now adds brain-injury adults to the list of people who can improve without punishment phases.

Bacon et al. (1998) looked like they disagreed at first. They gave non-contingent escape breaks and saw quick drops in disruption. Their breaks were fixed, while M et al. slowly returned work. The two tactics differ, yet both remove the escape reason for acting out. One is steady relief; the other is a slow rebuild.

If your client swears, hits, or bolts to avoid work, try removing the task entirely, then bring it back in tiny steps. Track the behavior each step. You may get large drops without adding extra consequences. This saves time, keeps staff safe, and respects client dignity.
