Using technology to improve assessment and treatment of vision in children

Measuring vision is important in a range of clinical settings, from monitoring the effectiveness of gene therapies for blinding eye conditions through to early detection of age-related eye diseases like glaucoma.  My lab uses technologies such as infrared eye tracking and virtual reality to measure and correct vision in groups that can be difficult to assess and/or treat. In this talk I will give overviews of several projects – inspired by basic psychophysical research – that deliver more reliable visual assessment, and novel platforms for treatment, of children.

Attention shapes visual perception

Visual attention is essential for visual perception. Spatial attention
allows us to grant priority in processing and selectively process
information at a given location. In this talk, I will present empirical
studies:

(1) investigating how endogenous (voluntary) and exogenous (involuntary)
covert attention improve contrast sensitivity at attended locations and
have concurrent costs at unattended locations;

(2) testing predictions of a normalization model of attention; (3)

Learning to read and dyslexia: from theory to intervention

How do children learn to read? How do deficits in various components of the reading network affect learning outcomes? How does remediating one or several components change reading performance? In this talk, I will quickly summarize what we know about how children learn to read. I will then present the first full-blown developmentally plausible computational model of reading acquisition. The model will be used to understand normal and impaired reading development (dyslexia).
