A variety of cognitive tasks have been studied by using eye movement data. Reading, problem solving and visual search are familiar examples. The approaches used in such cognitively-oriented eye movement research are as varied as the tasks, but they can be divided into two major categories: (i) varying the high-level parameters of the task to find out how perceptual and cognitive factors influence eye movement patterns, and (ii) using eye movement data as a protocol to gain insights about the underlying cognitive process. I will discuss some recent insights that eye movements have provided in the study of cognitive processing and theoretical issues inherent in modelling eye movement data.
