Infants' Age and Walking Experience Shapes Perception-Action Coupling When Crossing Obstacles.

This study examined the effects of age and walking experience on infants' ability to step over an obstacle. We videotaped 30 infants with one (mean [ M] age = 12.6 months), three ( M age = 14.

Ideal treadmill speed to stimulate stepping in infants.

Background: The motorized treadmill elicits stepping in infants, however the effects of belt speed on treadmill-elicited stepping patterns are still unknown.

Objective: To examine the effect of belt speed on treadmill-elicited infant stepping.

Methods: Six normally developing infants, aged between 11 and 13 months and acquiring independent walking, were videotaped while stepping on a treadmill at four belt speeds (0.
