Volume 1, Chapter 04: Blinking and Looking: An Eye-Tracking Approach to Studying Cognitive Processing Differences in Individuals with Speech, Language, and Communication Disorders



Taken together, large advances in eye-tracking technology has lead to advances in understanding underlying cognitive processes in child and adult populations exhibiting neuro-typical 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 non-volitional (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.
