Coupling Prior Model of Visuo-Proprioception Location Estimates and Fit with Psychophysical Data. Top panels; average psychophysically measured (solid line) and modeled (dashed line) visuo-proprioceptive MAP-decoded location estimates after fitting λ and σ2c and as a function of the placement of visuo-proprioceptive stimuli and hand visibility (left: visible; right: invisible). Proprioceptive stimuli (illustrated long the x-axis) are placed either 200 mm rightward, 100 mm rightward, 50 mm rightward, 25 mm rightward, 25 mm leftward (−25mm), 50 mm leftward (−50mm), 100 mm leftward (−100mm), or 200 mm leftward (−200mm) relative to the visual stimuli. Bottom panels: Fitted visual (red) and proprioceptive (black) bias (y-axis) as a function of measured bias (x-axis), for both when the hand was visually rendered (left) and not (right). Overall, there appears to be no systematic fitting error. Error bars represent +/−1 S.E.M.
