ABSTRACT

Taken together, large advances in eye-tracking technology has led to advances in understanding underlying cognitive processes in child and adult populations exhibiting neurotypical and deficits in their developmental trajectories. In this chapter, we first discuss the historical progression of eye-tracking technology that has left us with advanced techniques for collecting time sensitive and moment-to-moment changes in cognition. Volitional (saccades, fixations, and dwell times) and nonvolitional (blinking and pupilometry) measures were evaluated and described with reference to the types of cognitive processes that can be and have been measured in neuro-typical populations and populations with communication sciences and disorders. The chapter ends on special considerations for eye tracking with young children and children with communication disorders while providing special considerations for creating an eye-tracking environment that maximizes the ability to evaluate the most appropriate linking hypothesis between measurement and cognition.
