Our researchers are currently studying visual development in adults and children with amblyopia (sometimes referred to as "lazy-eye") or strabismus (misaligned eyes).
We are currently looking for: (12/1/14) Adults diagnosed with Amblyopia.
Our researchers want to learn more about how infants develop different visual abilities -- like detecting a face, keeping track of changing images, or perceiving depth -- and how changes in the brain guide the development of these abilities.
In our lab we study how children with Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) process visual and/or auditory information. We expect that this work will provide clues about ASD and ADHD, and will help to design diagnostic and therapeutic tools.
We are currently looking for: (9/1/17) Children with ADHD. Age: 4 - 9
Symmetry is a fundamental principle of perceptual organization and contributes to multiple aspects of vision. Symmetry in two-dimensional visual images can be understood at a fundamental level through the mathematics of group theory. Motivated by this framework, we are determining how the brain encodes the known mathematical properties of symmetry. To accomplish this goal, we have developed an approach to generating experimental stimuli that systematically varies the fundamental symmetry properties of images. These stimuli and their basis in group theory give us a complete and theoretically motivated framework for studying symmetry.
Early Visual Pathways Study
For many clinical conditions or forms of eye disease, early detection promises access to the most effective means of treatment. With help from Dr. Jeffrey Goldberg and other colleagues at Stanford's Department of Ophthalmology, this study aims to develop a screening test for detecting early stage sof glaucoma. EEG brain-wave comparisons between clinical participants and those without eye disease will illuminate patterns in visual processing connected to developing stages of glaucoma. Participants with normal or corrected vision are needed to test different versions of the screening test.
3D Natural Scenes Study
Understanding 3D information in the surrounding world is an essential component in navigating through space, interacting with objects, and much more. Researching 3D visual processing in natural scenes offers to provde insight into the robust information humans glean from images resembling our daily environments. To this end, the study utilizes EEG to measure brain-wave activity while viewing these scenes, as well as perceptual measurements captured by key presses.
Transcranial Electrical Stimulation Study
Brain activity is comprised of countless, tiny electrical impulses transferred between neurons. This project investigates methods for improving vision through electrical brain stimulation. We measure how perceptual judgments or brain-wave responses are modified by very weak electrical fields applied to the scalp.
