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.


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,  form, visual attention, and depth;  several Maxwellian-view optical systems for studies of visual adaptation; and calibration equipment.   Ties with colleagues at nearby institutions (such as Boston University, Harvard University, the New England College of Optometry, and the Schepens Eye Research Institute) expand both the physical and intellectual resources of the group.


Peter Bex

Specialization: Basic and clinical vision science
Laboratory: Translational Vision Lab

Dr. Bex’s clinical research uses behavioral and computational techniques to study the pathological processes in blinding eye diseases including Age-related Macular Disease, Glaucoma and Amblyopia. My research aims to understand the bases and implications of these blinding eye diseases with the goal of developing efficient and sensitive methods for early diagnosis and to measure the presence and progression or remediation of vision loss. Treatment of many eye diseases with conventional ophthalmic techniques is of limited benefit, my lab therefore develops new technologies and novel therapeutic approaches that help to maximize residual visual function and promote the most effective rehabilitation.

Rhea Eskew

Specialization: Visual Perception and Psychophysics
Laboratory: Visual Psychophysics Lab
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.

Adam Reeves

Specialization: Visual Perception
Laboratory: Visual Perception Lab
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.

Affiliated Faculty

Ennio Mingolla

Professor and Chair, Department of Speech-Language Pathology and Audiology
Adjunct Professor, Department of Psychology

Dr. Mingolla works on development and empirical testing of neural network models of visual perception, notably the segmentation, grouping, and contour formation processes of early and middle vision in primates, and on the transition of these models to technological applications.
