• Research Interests:How does the brain determine where a movement goes? Our laboratory uses behavioral and computational techniques to study how vision and cognition interact to produce movement commands. We study the generation of saccadic eye movements, which are used to shift the eye rapidly to permit clear seeing. The control of movements of the eyeball is much simpler than that of other movement systems, such as those controlling arm or leg movements, which need to compensate for mechanical load and have many more degrees of freedom. This relative simplicity of the eye movement system makes it ideal for studying how vision and cognition produce movement. Our current work focuses on three aspects of this issue: 1) How does scene-based visual memory facilitate the programming of saccades in complex, real-world visual scenes? 2) How can instruction and practice modify the vectors of reflexive saccades? 3) How do visual attention and perception influence and reflect the programming of saccades?
