Colgate ERP Lab



Research conducted in my lab is focused on how real-world visual information is encoded in the ventral processing stream of the human visual brain and subsequently perceived by the human observer.  For numerous reasons, the work conducted in my lab emphasizes the use of real-world stimuli (e.g., actual images from our environment ranging from landscapes and cities to images of common everyday objects or human faces) when investigating how we sense and ultimately perceive the world around us.  The primary motive is due to the fact that most of what vision scientists know about how our brains process the visual world around us is based on rather abstract, un-naturalistic visual stimuli.  Unfortunately, many of the predictions made from the volumes of work conducted with such artificial stimuli, often fail to predict how our brains process visual information that we encounter on a day-to-day basis.  Accordingly, the experiments conducted in my lab, as well as in collaboration with labs at other universities, cover a broad range of perceptual abilities on either a developmental time-scale or in adults, ranging from simple size, orientation, or contrast judgments within natural scene images, to more complex tasks involving human face discrimination/recognition and categorization of different visual environments.

Areas of interest include human perception of real-world visual stimuli (natural scene perception); shape/object perception; human face recognition/discrimination; human eye movements and gaze; visual attention; biological motion perception; relationship between natural image statistics and visual development; cortical implications of amblyopia; visual texture segregation and contour integration; neural biases involved in the aesthetics of visual art.

Students in my lab (either as thesis students or undergraduate research assistants) are exposed to a multitude of behavioral (i.e., psychophysical) and neurphysiological techniques for studying human visual perception & cognition, all of which are geared toward each student's level of education. Upon joining the lab, students are immediately involved in ongoing projects (visit the "Research" link to the left for more details) and encouraged to eventually conceptualize, design and execute new projects inline with their own interests.
