Prospective head tracking: head movements, accuracy and timing in relation to a circular object motion

In this study, kinematic and video recordings were made of the eye- and head tracking of an object revolving in a vertical plane in two groups of infants (6- and 12-month-old) and one group of adults. The study had two purposes. The first concerned infants' abilities to negotiate the target trajectory when being forced to extensively recruit the head. The second addressed the question whether the same underlying neural controller drives both eye- and head motor systems. It was found that head tracking ability is functional already in 6-month-old infants. However, infants of both age groups displayed more extensive head movements and less accuracy compared to adults. This finding is in line with previous research on one-dimensional horizontal head tracking in infants. Infants also showed less developed timing between head movements and vertical object motion, supporting the argument that both eye- and head tracking have a common developmental trajectory.
