The current study showed that visual fixation of obstacles is not required for rapid and adaptive naviga-
tion of obstacles. Children and adults wore a wireless, head-mounted eye-tracker during a visual search
task in a room cluttered with obstacles. They spontaneously walked, jumped, and ran through the room,
stepping up, down, and over obstacles. Both children and adults navigated adaptively without fixating
obstacles, however, adults fixated less often than children. We discuss several possibilities for why obsta-
cle navigation may shift from foveal to peripheral control over development.
