- Abstract
The precise visual perception of self-movement is essential for locomotion and postural control. In the second half of the first year, infants become highly responsive to peripheral lamellar optic flow (PLOF) specifying self-movement. Past studies on infant responsiveness to PLOF have only contrasted postural responses to optic flow patterns differing in overall direction of movement, e.g., horizontal vs. downward movement. This study investigated whether infants show differential responses to PLOF specifying different degrees of downward movement. Twenty-seven 9-month-olds were presented with PLOF specifying 30° descent, 10° descent, and horizontal forward movement in a virtual moving room. The infants showed degree-appropriate postural responses to each of the three conditions, as well as elevated cardiac accelerations to 30° descent. These results show that infant reactions to optic flow are highly attuned to the specific direction of the perceived movement.
