INTERNAL CLOCK

"We are impressed with the striking changes in infant behavior over the first year of life. As the visual system matures during the first six months, infant behavior often appears dominated by visual orienting. Later, as executive control develops, we see behavior controlled by the infant's own internal agenda and observe the origins of language. Thus there is good reason to believe that the networks of local brain activity... play a role in the appearance of much human behavior.

For this reason it becomes important to determine if we can measure attention in infants and observe its development. To explore the development of the visual orienting network over the first year of life, we use tasks... in which the subject's attention is first drawn by a cue and then by a target. Infant's eyes are fixed on a central screen at the start of each trial, and two peripheral screens are used to attract their eyes. We record the eye movements on TV tape so that they can be analyzed frame by frame. We use these eye movements as the behavior to be measured, just as in adults the key press serves as an overt measure from which we infer covert shifts of attention."
