In the present study, we examined if young infants can extract information regarding the directionality of biological motion. We report that 6-month-old infants can differentiate leftward and rightward motions from a movie depicting the sagittal view of an upright human point-light walker, walking as if on a treadmill. Inversion of the stimuli…

This study examined 6-month-old infants' abilities to use the visual information provided by simulated self-movement through the world, and movement of an object through the world, for spatial orientation. Infants were habituated to a visual display in which they saw a toy hidden, followed by either rotation of the point of observation through the…

Investigates infants' scanning of two compound stimuli by presenting features (either squares or faces) inside a frame, the frame alone, and features alone. The apparent disappearance of external bias at about 21 months appears to apply to the scanning of only some compound figures. For schematic face figures, no external bias was found.…
