MPI CyberMotion Simulator: Implementation of a Novel Motion Simulator to Investigate Multisensory Path Integration in Three Dimensions
Published on: May 10, 2012
Abstract:
We investigated learning of spatio-temporal interpolation in depth and its relation to spatio-temporal interpolation in two dimensions by means of a vernier discrimination task. Performance improved with training but improvement did not or only partially transfer between opposite directions of motion in depth. Improvement was also at least partly specific for the eye and for the direction of two-dimensional motion used during monocular training. This specificity might explain the apparent specificity of interpolation in three dimensions. Training with stimuli moving in two dimensions increased performance for a stimulus moving in depth. The results indicate that improvement in spatio-temporal interpolation occurs at least partly on a stage preceding stereoscopic vision, and are a rare example for transfer of improvement between different perceptual tasks.
