We investigate the relation between the psychological and physiological mechanisms involved in the basic processes of visual perception and attention. The theoretical framework for our research draws from work in perception, cognitive neuroscience, cognitive psychology and neurophysiology

Our current research has four overarching goals: 

1) To characterize how attentional mechanisms affect the spatial and temporal aspects of early visual processing in visually intact adults.

2) To characterize how the interaction of covert attention and eye movements affects visual processing

3) To understand whether and how attentional mechanisms affect perceptual learning for a variety of measures, including motion discrimination, orientation discrimination, and acuity.

4) To investigate whether and to what degree these attentional mechanisms affect the spatial and temporal aspects of early visual processing in clinical and special populations, including adults with Autism Spectrum Disorder, ADD/ADHD, amblyopia, the elderly, and young children. 

To quantitatively investigate the relation between brain and behavior, we employ a wide array of methodology, including psychophysicseyetrackingneuroimaging (fMRI, MEG, EEG and TMS), and computational modeling.
