Using individual
differences to optimize and understand visual
processing
Dr. Kassandra R. Lee
Abstract:
Individual differences
are a pervasive property of visual perception, and arise at many
different levels, from the optics of the eye to the nature of conscious
experience. These differences are important for optimizing perception and
performance (e.g. to tailor technology and information for individual
observers rather than a single “standard observer”). To illustrate
this approach, I will review studies where I have explored how
differences in color sensitivity could be efficiently characterized to
calibrate displays specific for each user. I touch on the ways that
applied applications from these studies can inform how properties of
human vision contribute to understanding the variety of human experience
in advancing science and technology. In other cases, individual
differences can also provide a powerful tool for studying the mechanisms
of perception (e.g. to identify the cognitive and neural sources of the
differences and the processing machinery they imply). To highlight this
aim, I will also describe a series of studies I have conducted to
leverage individual differences to examine the visual codes underlying
human face perception.
Bio:
Kassandra R. Lee is a
graduate member of the Neuroscience program, where she has worked in Dr.
Michael Webster's lab since 2018. With previous interests and work in the
field of vision and low vision research, her current research utilizes
psychophysical, computational modeling, and neuroimaging methods to study
the processing of high-level stimuli, such as faces. She is also
investigating individual differences in color vision and perception. More
generally, Kassandra's research questions aim to address how we perceive
and adapt to our visual world.
