Study Information for Parents of Infants in San Diego:

We are recruiting infants and children who are deaf or have signing parents.  We are also recruiting premature infants who were born early.    Our studies help us better understand how our experiences shape our visual and cognitive abilities.  Our studies typically involve one or two visits, with testing taking about 20-30 minutes.   We try to ensure that our parents, infants, and children have an enjoyable time.   For more information, click here to find out more about our studies.

 

My Research Interests:

I am an experimental visual psychophysicist studying visual perception in infants, children and adults.  I study different populations including infants who were born prematurely and have had extra visual experience outside the womb, individuals who had congenital eye disorders, and individuals who are deaf signers and have had unique reliance on visual input.   The paramount goal of studying these populations is to understand the effects of early atypical sensory experiences on different aspects of visual perception (such as contrast, color, motion, form, depth, and faces) and the underlying neural mechanisms.  Such work will unveil how the absence of sensory input (as in the case of blindness or deafness) alters remaining, intact perceptual abilities, and how experience with a visual language modality impacts perception, cognition, and language processing.
