Research Interests
The research focus in Ben Backus' lab is the integration of visual information
for depth perception in humans. How does the visual system make use
of multiple sources on information? Sensory measurements are noisy (and
inherently ambiguous even in the absence of noise), so the visual system
must guess what scene in the world was most likely to have caused the
observed sense data: this guess is what it constructs in a visual percept.
Current work aims to determine (1) the optimal rules for building reliable
percepts under such conditions, and whether these are the rules used
by the visual system; (2) the mechanisms of stereoscopic depth perception,
(3) conditions under which physically different stimuli come to have
identical representations within the visual system, and (4) what mechanisms
the visual system uses to keep itself calibrated.
