Perception

Members of the Perception Group use computational, electrophysiological and behavioral techniques to study a variety of issues in perception, with a strong focus on vision.

Facilities

State-of-the-art facilities include computer-based laboratories for precise control of visual stimuli, data collection and analysis, and modeling. Laboratory equipment includes computer-controlled displays for studies of color and form, a system for high-density EEG measurement with cortical source localization, a Wheatstone stereoscope, eyetrackers, several Maxwellian-view optical systems, equipment for ERG measurement in mice, rats, and humans, and equipment for basic mouse psychophysics. Ties with colleagues at nearby institutions (such as Boston University, Harvard University and the Schepens Eye Research Institute) expand both the physical and intellectual resources of the group.

Faculty

Rhea Eskew

Specialization: Visual Perception and Psychophysics
Laboratory: Vision Laboratory
Dr. Eskew collects psychophysical data and employs it in the development of quantitative models of visual processes. His current interests include color detection and discrimination, light adaptation, response times and their relationship to thresholds, and plasticity in the visual system.

Yury Petrov

Specialization: Visual Perception
Laboratory: Visual Perception Laboratory
Dr. Petrov studies low-level visual mechanisms in humans, including stereoscopic vision, shape processing, and contextual effects such as visual masking and crowding. His present interests include the role of attention in crowding, physiological mechanisms of overlay suppression and surround suppression, and the neural basis of perceptual switches for ambiguous visual stimuli. His research is based on psychophysical methods, accompanied by high-density EEG recordings with cortical source localization.

Frank Naarendorp

Specialization: Visual Perception and Psychophysics
Laboratory: Laboratory for ERG Studies
Dr. Naarendorp’s research is aimed at understanding the relationship between neural activity in the retina and vision. His work involves both human and animal subjects. Experiments conducted on humans are psychophysical in nature. On animals he uses psychophysical, electrophysiological, and pharmacological techniques. For both humans and animals, Dr. Naarendorp seeks to describe response characteristics of photoreceptors and their associated retinal pathways. Studies of this kind are important from the standpoint of basic science because they provide insight into the early stages of information processing by the nervous system.

Adam Reeves

Specialization: Visual Perception
Laboratory: Visual Perception Laboratory
Dr. Reeves studies human visual perception and visual information processing. His research concerns the various roles of attention, imagery, recognition, color, adaptation, short-term memory, and masking, in the human visual system. Psychophysical methods are used to answer theoretically motivated questions in each area.
