Promoting reciprocal interactions via peer incidental teaching.

★ The Verdict

Train typical preschool peers to use incidental teaching during free play to boost reciprocal interactions of classmates with autism.

01Research in Context

01

What this study did

Three preschoolers with autism played in a regular classroom.

The researchers taught four typical classmates to use "incidental teaching."

During free play the peers waited for the child to show interest, then asked questions like "What color is that?" and gave hints until the child answered.

Adults coached the peers at first, then stepped back.

The team counted how many back-and-forth turns happened between the children.

02

What they found

All three children with autism started having longer two-way conversations.

Their reciprocal turns doubled or tripled compared with baseline.

The gains stayed high after adults stopped helping the peers.

When the kids moved to new toys, the talking dropped some, showing limited generalization.

03

How this fits with other research

Kydd et al. (1982) showed that changing how adults answer repetitive questions also builds turn-taking.

Raslear et al. (1992) moves that work forward by letting typical peers deliver the prompts instead of grown-ups.

Tanguay et al. (1982) used the same multiple-baseline design with preschoolers and found self-instruction helped desk work; here peer prompts helped social talk.

Root et al. (2017) later proved that ADOS Social Communication scores match real peer chatter, so you can use those scores to pick who will benefit most from peer teaching.

04

Why it matters

You can turn classmates into tiny therapists during recess.

Pick one or two sociable peers, teach them to wait, ask, and prompt, then let playtime do the work.

Track conversation turns for a week; if they rise, fade yourself out and celebrate.

Start with one toy area, then add others to widen the gains.

03Original abstract

This study evaluated peer incidental teaching as a strategy for increasing reciprocal peer interactions by children with autism. Three typical preschoolers were trained as peer tutors for 3 young children with autism. During a classroom free-play session, peer tutors used incidental teaching to obtain verbal labels of preferred toys by children with autism. A multiple baseline across the 3 target children showed replicated positive effects of the intervention. Adult supervision and assistance were then faded systematically, with resulting maintenance of increased reciprocal interactions. Multiple measures of the extent and limits of generalization suggested that 1 child increased interactions in free-play periods throughout the day, but none of the children showed increases at lunch. Teacher and peer ratings supported the social validity of positive findings.
