Setting effects on the occurrence of autistic children's immediate echolalia.

The team watched autistic children in short work sessions. They changed who gave the task and how new the toys were.

Kids met either a brand-new adult or their usual teacher. They also got either new puzzles or their everyday ones.

The goal was to see when the children echoed words right back.

Echo talk shot up when both the adult and the toys were new.

If only one thing was new, echoing stayed low. Familiar keeps echoing quiet.

Neef et al. (1986) ran the same idea the same year. They swapped echo talk for hand flaps and got the same jump when the adult was new.

Baum (1989) added a twist. Kids with less language skill echoed more. That backs the idea that unfamiliar tasks feel harder, so kids echo.

Singer-Dudek et al. (2021) moved the test to class. Autistic kids echoed and flapped less when they worked with typical peers instead of their usual special-ed group. New people can help, not just stress.

Keep one thing the same when you teach. Use the same staff or the same materials, not both new. If you must swap, pre-show the toys or let the child meet the new teacher first. Less echo means more room for real talk.
