Posture Matters: Object Manipulation During the Transition to Arms-Free Sitting in Infants at Elevated vs. Typical Likelihood for Autism Spectrum Disorder.

PMID 35086427WHAT IT FOUND
Infants at elevated likelihood for autism spent significantly less time grasping toys when sitting independently compared to supported sitting.
This postural demand reduced their total object manipulation time, potentially limiting early learning opportunities.
Key findings
01Infants at elevated likelihood for autism spent significantly less time grasping toys in independent sitting than in supported sitting, whereas typical-likelihood infants showed no such difference.
02Transfer rates (moving objects between hands) increased as infants gained sitting experience but did not differ between groups or postures when controlling for grasping time.
03Because elevated-likelihood infants grasped for less time in independent sitting, they had fewer absolute opportunities to transfer objects, despite similar transfer rates per minute of grasping.
