Walker Lab
The goal of our laboratory is to build computational, predictive models of voluntary eye movements in both healthy and diseased states.
Verghese Lab
Our laboratory studies the mechanisms of healthy vision and action, as well as the basis of attention and visual adaptation in clinical populations.
Calibration of eccentric power refractor
Eccentric power refractors need to be calibrated for accommodation and gaze position for individual participnats. Calibration however can be time consuming. We look at different conditions in which calibration is necessary or preferable.
The window of spatial attention in reading
In reading, visual information is extracted from a window around the gaze. For the first time, we looked at effects of word's processing load on the dynamics of this window over the course of a fixation when sequential saccades are made.
Parafoveal Crowding
Crowding increases with eccentricity, and is most readily observed in the periphery. During natural, active vision however, central vision plays an important role. Measures of critical distance to estimate crowding are difficult in central...
SKERI-VF
Walker et al (Renninger, Psomadakis, Dang & Fletcher, 2008) suggested a novel method to estimate the monocular scotoma area from perimetry data in macular degeneration based on (i) an optic-disc based estimation of the location of the fovea and (ii) the...
Adaptive Visual Strategies for Information Maximization in Individuals with Macular Degeneration
In this project we try to gain a better understanding of what visual strategies people use to gather information in the world.
Fovea Use During Smooth Pursuit
There is continuing debate as to whether smooth pursuit relies on the foveation of a moving target, especially when the target is compact. Previous studies have shown that gaze is placed on the center-of-mass of a target during saccadic eye movements. This research aims to understand whether...
