What this trial measures

  • Pursuit eye movements to peripheral moving stimulibaseline

    Pursuit eye movements are smooth eye movements with slow velocities (\< 15 degs/sec) that track the motion of visual stimuli when they are at the center of the visual field (Madelain and Krauzlis, J. of Vision, 2003). Here we will test the prediction that pursuit eye movements begin to track the motion of the stimulus located peripherally as an eye movement moves to the stimulus. The null hypothesis is that there will be no effect of the peripheral stimulus motion on the pursuit eye movements. We will measure eye movements using an infra-red eye tracker (Arrington, Inc) from 500 or more trials collected in each session. The distribution of pursuit eye movements will be computed for each subject to evaluate if there is significant pursuit along the direction of stimulus motion around the time of the saccade. The mean per participant will be determined and group effects evaluated.
