Perception

Perception is the process by which sensory cues are integrated to form a model of the world. Participating faculty come from Psychology, Computer Science, Philosophy, Biomedical Engineering, and the Biomedical and Health Sciences. Key research topics include computer vision, human psychophysics, visuomotor integration, philosophy of perception, and neuroscience. Collaborations among faculty and student researchers across this diverse array of topics and disciplines have contributed to the emergence of novel approaches, as well as to the formation of a stable and interactive community of perceptual scientists.

The interdisciplinary Perceptual Science Group was formally formed in 2006 with the support of an Integrative Graduate Education and Training Program (IGERT) from the National Science Foundation. The program supported more than 40 trainees, with graduates going on to careers in academics and industry. Perceptual Science integrates computational modeling and experiments across Psychology and Computer Science. It remains a major component of research and training at RuCCS, with frequent seminars and colloquia, as well as our annual Perceptual and Cognitive Science Forum.

Students are encouraged to take advantage of the opportunities to gain foundational training in both Computer Science and Psychology, and to embark on collaborative research across other areas. Opportunities are available for interdisciplinary team projects with fellow students by taking the novel course Integrative Methods in Perceptual Science, developed with support from NSF.

  • Kelvin Y. Kwan

    Molecular mechanisms underlying sensory and cognitive function in mouse models of human diseases. The lab is interested in understanding how mutations in chromatin remodeling proteins results in hyperactivity and circling behavior in mutant mice. Identifying transcriptome changes in affected neurons by deep sequencing will help us understand how the activity and development of these neurons have been altered. Our goal is to bridge the molecular changes in neurons to the abnormal behavior observed in these mouse models.

    My main research interests span from intonational phonology to prosody production and perception, within a Laboratory Phonology approach. More recently, my work has expanded to online measures (ERP, Eyetracking) of intonation and word processing/acquisition in both in L1 and L2, aimed at unravelling the impact of individual cognitive differences in linguistic production and perception.

    Research in my laboratory employs neurophsyiological, behavioral, and theoretical methods to explore how humans and rodent models learn information about the world and apply this knowledge to the neural processing of incoming sensory stimuli. We are also interested in how dysfunction in these processes could manifest in mental and neurological disorders.
