Eye Tracking, Pupillometry

eye trackingEye tracking is used by researchers to investigate human language development, language skills, and reading behavior. In language processing, eye movements are closely linked to the current focus of attention during sentence processing.  Pupillometry measures pupil dilation during language and cognitive processing. The idea here is that pupils dilate under processing load.

Linguistic abilities are assessed by tracking and recording eye movements and measuring pupil dilation in response to auditory and visual stimuli.
