AI Article Synopsis
- Scientists studied how newborn babies see and understand hands just a few days after they're born.
- They showed the babies different hand movements—some that made sense and some that didn't.
- The babies seemed more interested in the tricky hand movements, which might mean that even newborns start learning about how bodies move based on what they experience.
Article Abstract
The development of human body perception has long been investigated, but little is known about its early origins. This study focused on how a body part highly relevant to the human species, namely the hand, is perceived a few days after birth. Using a preferential-looking paradigm, 24- to 48-hr-old newborns watched biomechanically possible and impossible dynamic hand gestures (Experiment 1, N = 15) and static hand postures (Experiment 2, N = 15). In Experiment 1, newborns looked longer at the impossible, compared to the possible, hand movement, whereas in Experiment 2 no visual preference emerged. These findings suggest that early in life the representation of the human body may be shaped by sensory-motor experience.
