Characteristics of Eye Movements to Sesame Street from 8 to 26 Weeks of Age Several approaches to the study of the development of eye movements and visual attention in human infants have been presented in the literature. Often these studies have focused on “performance ” or behavioral characteristics of looking behaviors, while a few have evaluated the physiological characteristics of the eye movements themselves. While each of these approaches has provided valuable information regarding the development and integrity of the visual system and visual attention, there are reasons to question the generalizability of many of the findings to real-world behaviors. This study addresses some of those concerns by examining the development of eye movements and visual attention using behavioral and physiological characteristics of eye movements generated by infants from 8 weeks to 26 weeks of age while viewing portions of a Sesame Street movie. With regard to performance characteristics, developmental research has focused on different aspects of looking behaviors in effort to increase understanding of not only the behavioral course, but, through converging lines of evidence, also illuminate the neural substrates involved in visual attention. Developmental changes in some performance characteristics, such as proportions of looks made to peripheral targets (Aslin & Salapatek
