Identifying critical social interaction behaviors among high school students with and without disabilities.

Researchers watched high-school students with and without disabilities during free times. They counted how often the teens started real conversations. They listed six key behaviors that almost never happened on their own.

Without adult help, students rarely talked to each other across disability lines. The six vital acts—like asking a question or answering back—stayed missing. Spontaneous social life in high school was close to zero.

Laposa et al. (2017) ran a randomized trial that proves the point: when typical peers are trained to form lunch-bunch circles, friendships grow. Their work extends the 1999 list by showing one way to make the six behaviors appear.

Okuno et al. (2022) seems to disagree. They link social-skill gaps to social anxiety, not disability. The clash clears up once you see the 1999 study looked at all students, while Hide studied only teens with clinical anxiety.

Davis et al. (1994) used high-probability requests to spark initiations in preschoolers. Same goal, younger kids, clear gains—showing the six behaviors can be taught if you start small and prompt hard.

You now have a ready-made short list of six conversation targets. Stop hoping high-schoolers will just figure it out. Instead, borrow the peer-network script from Laposa et al. (2017): pick two typical peers, give them roles, and embed the six behaviors into lunch or club periods. Start there and social interaction finally shows up.
