The effects of teacher intrusion on social play interactions between children with autism and their nonhandicapped peers.

The team watched elementary students with autism play one-on-one with a typical classmate.

They changed how much the teacher stepped in. Sometimes the teacher stayed quiet. Other times the teacher gave lots of hints and prompts.

The goal was to see if more or less adult help changed toy play, talking, or problem behavior.

When the teacher backed off, kids touched toys a little more and played a bit longer.

Surprise: less teacher presence also meant fewer spontaneous words. Challenging behavior stayed the same either way.

The gains were small and mixed, so the authors call the results 'modest.'

Dolev et al. (2023) extends the same idea to preschoolers with developmental delay. They found that teachers who stayed non-intrusive during one-on-one play predicted bigger gains in language and self-help skills one year later.

Wolfberg et al. (2015) also boosted peer play, but they trained the typical peers instead of changing teacher prompts. Their Integrated Play Groups created bigger, lasting jumps in both pretend play and social talk.

Carr et al. (1985) tried simple operant training to raise toy contact two years earlier and saw almost no change. The 1987 study keeps the small-effect pattern, showing that just lowering intrusion is not enough for strong gains.

If you run social play sessions, treat teacher prompts like salt: a sprinkle can help, but too much drowns the flavor. Start by standing a step farther back and counting how often you talk. Pair this light touch with peer-training methods such as Integrated Play Groups for stronger, lasting play and language growth.
