"Spontaneous" transfer of stimulus control from tact to mand contingencies.

Two adults with severe intellectual disability got tact training only. They learned to name kitchen tools when shown each item.

No one asked them to request the tools. The test was simple: later, when they wanted a utensil, would they point for it anyway?

After the naming lessons, both adults started pointing for the tools they wanted. The mand came "for free"—no extra teaching required.

The study showed that tact-to-mand transfer can happen without direct mand training.

Rosenthal et al. (1980) looked like the opposite result. They taught children to mand item-by-item and saw little transfer to new cues. The gap is method: the 1980 study taught mands directly, while the 1990 study taught tacts first and let the mand emerge.

Gutierrez et al. (2007) and Hattier et al. (2011) later used motivating operations to set off mands. They still had to run extra probes or script fading. The 1990 paper is simpler—just tact training and wait.

Frampton et al. (2024) now urge us to watch for early pointing. Their tutorial echoes what the 1990 data already showed: a solid tact can turn into a mand when the want is strong.

You can save teaching time. Build a strong tact repertoire first—name items in play, snack, and work areas. Then create a natural want: withhold the item for a moment and look for a point, reach, or gaze shift. If the learner already names the item, that response may pop out as a request without extra trials. Start sessions with quick tact warm-ups; end them with brief EO probes to see if the mand appears on its own.
