The development of orienting object features during hand to mouth transport was studied in a group of infants between 6-12 months of age (N=60). The task was to bring a bottle to the mouth. The bottle was presented in six different orientations (up, down, toward, away, left, and right). To measure head movement, a 3D motion capture system (Qualisys) was used. The results revealed that older but not younger infants are able to plan actions based on the functional end of an object. Older infants take less time, are more successful at directing the nipple to the mouth, initially grasp the bottle in an efficient manner more frequently, and move the head less than younger infants. More broadly, the results offer insights into how infants become more efficient in feeding tasks as they get older. / 1 / Wendy P. Jung
