Use of chaining to increase complexity of echoics in children with autism.

Three boys with autism, could echo words but could not retell a short story.

The team broke each four-sentence story into four picture cards. They taught the boys to point to a card, read the printed sentence aloud, and then say it without the card. Each step was mastered before the next was added, building a four-link chain.

After 10-15 sessions all three boys could look at the four pictures and retell the whole story without prompts.

The skill spread to new stories and the boys used longer sentences in free play.

Delamater et al. (1986) first showed that simple prompts can stop echolalia and create correct answers. Wilkins et al. (2009) extend that work by using chaining to build longer, self-generated speech.

KELLEHEBERRYMAELLIOTT et al. (1962) also used a response chain, but to earn food. Both studies show that linking small steps into a chain produces big behavior change.

Lindsley (1996) argues that fluent talking is just free-operant chaining. This study gives a real-life example: once the story chain was fluent, the boys could tell it quickly and smoothly.

If a child can echo but cannot speak in full thoughts, break the thought into picture or word cards. Teach one card at a time, then chain the cards together. You will turn rote echoes into real stories in a few weeks.
