Cognitive and linguistic assessment using eye tracking

摘要

Methods for assessing cognitive and linguistic abilities by tracking and recording the eye movements of a patient in response to predetermined verbal and visual stimuli. The methods incorporate conventional eye-tracking technology to acquire eye-fixation location and duration measures for testing linguistic comprehension, working memory, attention allocation, and the effect of semantic associative priming. Visual stimuli presented in the methods are carefully designed to reduce visually distracting features. Verbal stimuli are carefully designed to control for numerous linguistic features.
