Increasing autistic children's spontaneous verbalizations of affection: an assessment of time delay and peer modeling procedures.

Four autistic children, ages 4–7, rarely said loving words.

The team tried two tricks: peer modeling and a 3–5 second pause.

Adults hugged the child, waited, then prompted “I love you” if needed.

They tracked how often the child said the words first, without help.

The pause worked fast. All four kids began saying “I love you” on their own within nine tries.

The words spread to the playground and to mom at home.

Peer modeling alone never sparked the words, even after many shows.

Attwood et al. (1988) later bundled affection into preschool games; kids played more together, showing the love words can travel farther when peers join the fun.

Macpherson et al. (2015) swapped the adult pause for a 30-second iPad clip of kids giving compliments during kickball; the tech trick also worked, proving the pause idea still lives in new clothes.

Lowe et al. (1995) trained classmates to use pivotal response play prompts; they got bigger, longer social jumps than the simple pause, so the pause is a solid first step, not the final stop.

You can add a 3-second hug-and-wait routine today. No toys, no videos, just still hands and eye contact. Once the words pop out, fade the prompt and watch the love spread to recess and home.
