Temporal coordination of joint attention behavior in preschoolers with autism spectrum disorder.

Warreyn et al. (2007) filmed preschoolers with and without autism during play. They timed every look, point, and word used to share attention.

The team coded who looked where and for how long. They wanted to see if autistic kids move their eyes and hands in smooth, back-and-forth turns.

The autistic children were slower and choppier. They often stared at the adult’s finger instead of the toy.

Typical kids shifted gaze from toy to partner and back in one quick loop. Autistic kids broke the loop or took extra seconds.

Giallo et al. (2006) saw the same sluggish starts one year earlier. Their autistic preschoolers also missed simple adult bids and talked less.

Liu et al. (2021) used a computer model and still found gaze-sync delays in older autistic kids. The timing problem lasts past preschool.

Lawton et al. (2012) gives hope: when adults taught joint-attention games for a few weeks, autistic preschoolers looked and smiled more. The skill can improve.

You now know the trouble is not just fewer joint-attention bids, but mistimed, bumpy ones. Teach the whole loop: child looks at object, then at you, then back at object. Use slow, exaggerated points and wait. If the child stares at your finger, gently shift the toy closer to your face so the gaze path is short and clear.
