Abstract:
Seeing and
perceiving the visual world is an active and often multimodal process that
involves orienting eyes, head and body towards an object of interest. It i
s also a highly dynamic process during which the eyes continuously scan the
visual environment to sample information. Eye movements are used in many c
ontexts and by many research disciplines, ranging from developmental and co
gnitive psychology to computer science and art history, to measure visual p
erception, object categorization, recognition, and other mental processes.<
br />My research group uses human eye movements as sensitive indicators of
performance in real-world interceptive tasks. Tasks such as catching prey o
r hitting a ball require prediction of an object’s trajectory from a brief
glance at its motion, and an ultrafast decision about whether, when and whe
re to intercept. I will present results from two research programs that use
eye movements as a readout of these types of decision processes. The first
series of studies investigates go/no-go decision making in healthy human a
dults and baseball athletes and reveals that eye movements are sensitive in
dicators of decision accuracy and timing. The second set of studies probes
decision making in patients with motor deficits due to Parkinson’s disease
and shows differential impairments in visual, motor and cognitive function
in these patients. I will conclude that eye movements are both an excellent
model system for prediction and decision making, and an important contribu
tor to successful motor performance.
