Explored early-developing predictions of object motion through 6-month-old infants' head tracking and reaching for moving objects. Found evidence for infants' extrapolation of object motion on linear paths, in accord with principle of inertia. This tendency was remarkably resistant to counter-evidence, observed even after repeated presentations of…
