Eye-tracking

Apples Test ScreenshotThe PLAN Laboratory is equipped with two SMI RED250-mobile eye-tracking devices. The RED250-m is a fully portable eye-tracker that allows members of the PLAN Lab to conduct eye-tracking research both in the lab and at remote locations. Eye-tracking technology allows for the naturalistic, continuous and temporally sensitive measurement of attention and cognitive processing. Individual measurements (including first fixation duration, gaze duration and saccade length) discretely reflect early automatic processing mechanisms and later integrative and/or strategic processes. Furthermore, pupil dilation serves as an index of gross neural activation. As such, eye-tracking serves as a powerful method to examine the time-course of information acquisition and integration among clinical and non-clinical populations. Currently members of the PLAN lab are using eye-tracking to investigate hemispatial neglect in stroke populations.
