ABA Fundamentals

A natural language teaching paradigm for nonverbal autistic children.

Koegel et al. (1987) · Journal of autism and developmental disorders 1987
★ The Verdict

Trade rigid tabletop trials for child-led play with natural reinforcers to get speech that travels beyond the clinic table.

✓ Read this if BCBAs teaching first words to non-verbal autistic children in clinic, home, or telehealth settings.
✗ Skip if Practitioners working only with fluent speakers or using PECS as the primary modality.

01Research in Context

01

What this study did

Green et al. (1987) compared two ways to teach first words to non-verbal children with autism.

One group got traditional table-top drills: adult picks the toy, child names it, adult gives a piece of candy.

The other group got the Natural Language Paradigm: child picks the toy, adult follows the child’s lead, and the toy itself is the reward.

The team used a multiple-baseline design across kids to see which format produced more speech that showed up in new places and with new toys.

02

What they found

Kids in the NLP group used their new words in more settings and with more items than kids in the drill group.

Language gains spread without extra teaching sessions.

03

How this fits with other research

Bachman et al. (1988) ran the same NLP playbook one year later, but had parents deliver it at home. All eight children talked more, and the gains showed up at the grocery store and at grandma’s house.

Fullana et al. (2007) stretched NLP even further, using it with older adults who had memory loss. The same loose, child-led style still boosted appropriate vocalizations in a day program.

Gevarter et al. (2021) moved NLP online. One Zoom training plus two coaching calls helped Latinx families increase back-and-forth turns and toddler signs.

Together these four studies form a tidy ladder: clinician-run → parent-run → adult population → telehealth. Each step keeps the core idea—follow the learner’s interest and let the reinforcer be the real thing—but drops the clinical walls.

04

Why it matters

You don’t need a bag of M&Ms or a perfect therapy room to start NLP. Grab the child’s favorite train, wait for a glance, say “train,” and hand it over. Repeat with snacks, bubbles, or YouTube clips. The 1987 paper shows this simple swap gives you wider generalization than drill cards. If parents ask what to do at home, point them to Bachman et al. (1988): the same loose script works in the living room.

Pick three highly preferred toys, place them in clear bins, and let the child choose; name the item once before handing it over and record how many times the child echoes or approximates across the session.

03Original abstract

The purpose of this study was to attempt to improve verbal language acquisition for nonverbal autistic children by manipulating traditional teaching techniques so they incorporated parameters of natural language interactions and motivational techniques. Within a multiple baseline design, treatment was conducted in a baseline condition with trials presented serially in a traditional analogue clinical format where the therapist presented instructions, prompts, and reinforcers for correct responses. Then, these variables were manipulated in the natural language teaching condition such that stimulus items were functional and varied, natural reinforcers were employed, communicative attempts were also reinforced, and trials were conducted within a natural interchange. Treatment and generalization data demonstrated that manipulation of these variables resulted in broadly generalized treatment gains. Implications for language intervention are discussed.
