Functional analysis and intervention of perseverative speech in students with high‐functioning autism and related neurodevelopmental disabilities

Kuntz et al. (2020) worked with two high-school students who had autism. Both boys repeated the same phrases over and over. The team first did a short functional analysis. They found the talk was rewarded by adult attention.

Next they tried a three-part plan. Adults stopped giving attention for the repeated phrases. They gave praise and tokens for new, on-topic comments. They also gave quick verbal hints like “Tell me something new” when the old phrase started again.

The perseverative speech dropped sharply for both students. Appropriate, on-topic talk rose at the same time. The gains held while the staff slowly gave less help and fewer tokens.

Migan-Gandonou Horr et al. (2021) got an even bigger drop in the same behavior. They used non-contingent attention plus extinction. No prompts were needed. The child’s talk stayed down for 28 months. The two studies look opposite, but the difference is the function test. Kuntz’s students needed help learning what to say instead. The 2021 child only needed the old payoff removed.

Briggs et al. (2019) show you can skip extinction if you make the reward for good behavior big enough. Kuntz adds the flip side: when the child does not know what to say, add prompts even if you already use extinction.

Green et al. (1987) review shows prompting works fast, but long-term data are thin. Kuntz kept the brief prompts and still saw lasting change, filling that gap.

If you have bright students who echo the same lines, run a 10-minute attention test first. When attention keeps the talk alive, pair extinction with DRA. If the child stalls or keeps looping, add short verbal cues right away. The combo cuts the old script and builds new, flexible speech in the same package.
