Clarifying inconclusive functional analysis results: Assessment and treatment of automatically reinforced aggression.

Saini et al. (2015) worked with a child whose aggression and running away had no clear social pay-off. The team first ran a standard functional analysis. The results were cloudy, so they guessed the behavior was automatically reinforced.

They taught the child to ask for a break with one easy response. Then they used a two-part schedule. Green cards meant ‘help gets attention now’; red cards meant ‘wait’. They slowly made the red periods longer while keeping problem behavior low.

The chained aggression and elopement dropped sharply and stayed low. The child used the new break request more and more. Gains held in new rooms and with new staff once the red-green signals were in place.

Greer et al. (2016) ran the same green-red thinning plan 25 more times and saw the same good results. This direct replication shows the protocol works across kids and settings.

Ramirez et al. (2025) built on the idea by starting with a fixed 60 s green / 240 s red schedule right away. Two of three children did fine; one needed a slower step-by-step fade. The study keeps the multiple-schedule logic but speeds the thinning.

Edelstein et al. (2025) swapped the multiple schedule for a caregiver-run cumulative timer. They still got a 94% drop in problem behavior across 14 children. The change shows parents can run FCT thinning at home without clinic staff.

You no longer need to pick between ‘extinction all day’ and ‘reinforce every response forever’. Add simple color signals, teach one mand, then stretch the wait time. The same plan has now worked for aggression, self-injury, and elopement in clinics, homes, and preschools. Try starting with a 60 s/240 s split next Monday; if behavior spikes, slow the pace. Keep the signals visible so the learner always knows when help is coming.
