Persistent primary reflexes affect motor acts: Potential implications for autism spectrum disorder.

Chinello et al. (2018) watched 12- to 17-month-old babies during play. They scored how long primitive mouth and hand reflexes stayed active. Parents also filled a short form about mild autism traits in the family.

All kids were neurotypical. The team wanted to know if stuck reflexes forecast weaker motor skills.

Babies who kept strong reflexes scored lower on fine and gross motor tests. Families with higher sub-clinical autism traits were more likely to have babies with sticky reflexes.

The link stayed even after the team controlled for age and sex.

Cunha et al. (2018) saw a similar early warning story. They tracked pre-term infants and found that delayed goal-directed moves at 6-9 months predicted later problem-solving gaps. Both studies say: watch infant motor markers closely.

Perez et al. (2015) carried the idea into school age. They showed that fine motor skill at six years predicts math scores in kids with cerebral palsy. Alice’s reflex data now stretch the chain even earlier: a simple 30-second reflex check in infancy may flag future academic as well as social risk.

Matson et al. (1994) looked at adults with autism and found they learned blink reflexes faster but with odd timing. Alice’s babies had reflexes that would not fade. Together the papers hint at a life-long cerebellar-based timing issue that starts in the first year.

You can spot risk before red flags show up in language or social play. Add a quick primitive reflex screen to your 12-month motor assessment. If reflexes linger, weave in daily movement games that promote rotation, grasp, and oral-motor shifts. Share the finding with parents so they understand why extra motor practice now may buffer later social-communication delays.
