Antecedent stimulus control: using orienting cues to facilitate first-word acquisition for nonresponders with autism.

Matson et al. (2009) worked with nonverbal children with autism who had not spoken after months of standard verbal teaching. The team first watched each child to see what sound or sight made the child turn toward an adult. They then used that personal cue right before showing a toy and saying its name. The design was a multiple baseline across kids, so the cue started at different times for each child to show the cue, not something else, caused any new words.

The cues were tiny and unique. One child looked up when he heard a soft click, another when the adult tapped the table. These micro-signals lasted only a second and came right before the adult model.

Every child began to echo or say the target word once his personal cue was added. Some children kept the new words even after the cue was faded. The study showed that a silent, child-specific orienting cue can unlock first speech in kids who had made zero progress with regular models alone.

Cooper (1997) first argued that visual cues should be tried when preschoolers with autism ignore spoken lessons. L et al. now add auditory or tactile cues to that toolbox and give single-case proof that the idea works. Baharav et al. (2008) paired caregiver video with an FM auditory trainer and also saw first words pop out, but they used a whole video screen; L et al. prove that a much smaller, momentary cue is enough.

Gray (2024) used the same multiple-baseline design to teach receptive words in short clinic bursts. Both studies show quick language gains with tight single-case control, but L et al. target expressive first words while Gray targets understanding.

If you have a silent preschooler who has plateaued with standard echoic trials, probe for a micro-cue that orients the child toward you. It might be a finger snap, a whisper, or a tiny light. Insert that cue right before your model for five trials, then fade it once speech starts. This low-cost tweak can turn nonresponders into speakers without extra hours or new staff.
