Functional analysis and treatment of social-communicative behavior of adolescents with developmental disabilities.

Two teens with intellectual disability kept blurting silly or rude comments during class. The team first watched when the behavior happened. They saw classmates laugh or give eye contact after each outburst. That social payoff kept the problem alive.

Next the students learned to count their own good social acts. They used wrist counters. Each polite comment, question, or compliment earned a click. The clicks turned into preferred break time with peers.

Within days the outbursts dropped by a large share. Polite talk rose from near zero to 10–12 times per period. Teachers and classmates rated both teens as more likeable. Gains lasted the whole semester with no extra rewards needed.

Marcell et al. (1988) did the same thing earlier with self-injury. They also taught communication to get the same social reinforcers. The 1997 paper shows the idea works for milder, social-only problems.

Hui Shyuan Ng et al. (2016) later tested a full teaching package for kids with autism plus ID. They got the same social gains, proving the strategy crosses diagnoses.

Orsmond et al. (2009) looks opposite at first glance. They cut problem behavior by changing the room, not the student. Both studies start with a quick functional analysis. One tweaks the context; the other teaches a skill. Pick the path that fits your classroom resources.

You can run a five-minute functional analysis in class. Watch what happens right after the joke, insult, or noise. If peers or staff give eyes, laughs, or scolding, you found the fuel. Hand the student a counter and teach them to rack up clicks for any replacement that earns the same social juice. Breaks, high-fives, or shout-outs can buy the first week of clicks. After that, the new social contact itself keeps the skill alive.
