Increased parent reinforcement of spontaneous requests in children with autism spectrum disorder: effects on problem behavior.

Robertson et al. (2013) worked with families of children with autism at home. Parents were taught to give the same reinforcer for both spontaneous requests and for problem behavior.

The team used an ABAB reversal design. When problem behavior earned the toy, parents later gave the toy only for requests. They measured which response the child used more.

Children quickly chose to ask instead of act out. Problem behavior dropped when requests paid off.

The effect reversed each time the condition changed. Reinforcement, not just teaching, drove the shift.

Pierce et al. (1994) showed the same idea at school. Teachers prompted students with disabilities to ask for help; disruptive behavior fell. The mechanism matches, but E et al. moved it to the living room with parents in charge.

Charlop et al. (1985) first taught autistic kids to speak up using time-delay prompts. E et al. kept the spontaneous request goal but swapped prompts for pure parent reinforcement, proving the response still grows without adult cues.

Carnett et al. (2020) extends the logic to speech-generating devices. Their children learned to ask 'where' questions on an iPad. Both papers confirm FCT works across vocal words or electronic voice, so pick the modality the child already has.

DeLeon et al. (2003) started with a functional analysis, then taught wheelchair-movement requests to replace aggression. E et al. skipped the formal FA but still matched the reinforcer; together they show you can either assess first or simply observe what the child wants and then pay the same item for a request.

You can run this tonight. Watch what the child is willing to tantrum for—cookie, iPad, tickles. Tell parents to give that same item the instant the child asks, even if the ask is just a word, sign, or picture. Do not wait for perfect speech. The study says the behavior will swap because the same payoff now travels the easier route. Coach parents to stay neutral when problem behavior still happens—no cookie, no eye-roll—then deliver immediately when the request appears. In one weekend you may see the first dip in problem behavior and a nice bump in spontaneous communication.
