Intervening to Prevent Unwanted Touching of Museum Displays: Incorporating an Observing Response with Three Prompting Conditions

Staff placed a double-sided sign in front of a museum display.

They asked every visitor to walk around the sign before looking at the exhibit.

Three sign types were tested: a plain directive, a short why-we-do-this note, and the same note plus a stop-hand picture.

An observer counted how many people touched the glass after reading.

All three signs cut touching equally well.

Visitors who walked around the sign never touched the display.

The simple act of walking served as an observing response that made the rule stick.

Crane et al. (2008) and Farmer-Dougan et al. (1999) used the same tool—an observing response—in very different places.

They taught adults and children with disabilities to point or name items during matching tasks.

Their gains faded as soon as the pointing stopped, an apparent contradiction to the museum result.

The difference is the walk-around response stayed in place; the sign never moved, so the prompt never left.

Ruser et al. (2007) also showed that prompting compliance works, but they trained parents to give three-step prompts.

Fullerton et al. (2024) prove the prompt can live in the environment instead of in a person.

You can park a simple prompt in the space, not in your mouth.

Try adding a quick physical step—turning a card, stepping on a mat, or walking around a cone—before clients use shared materials.

The prompt stays, so the behavior stays, and you free your hands for teaching instead of reminding.
