In 2004, McMurray and Aslin edited for "Infancy" a special section on eye tracking. The articles in that special issue revealed the enormous promise of automatic eye tracking with young infants and demonstrated that eye-tracking procedures can provide significant insight into the emergence of cognitive, social, and emotional processing in infancy. Since that time, there has been an explosion of research using eye tracking with infants. As research has progressed, however, it has become clear that the main value of automatic eye trackers is not as an unbiased replacement for human coding of global looking. Automatic eye tracking presents several challenges that, in many cases, make it unnecessarily cumbersome for use in studies that could otherwise be performed with traditional human coding of looking times. In this article, the author details some of the challenges presented by automatic eye tracking and then describes how, despite these challenges, automatic eye tracking can be used to address new and exciting questions about the infant mind.
