On the screen we can see a 'gaze plot' - this is a post-recording process where the fixations and saccades are overlain on the stimuli for initial visual interpretation.On the screen we can see a 'gaze plot' - this is a post-recording process where the fixations and saccades are overlain on the stimuli for initial visual interpretation.
