Experiment I: 3D tracking. Tracking motion-through-depth is impaired relative to tracking frontoparallel motion. Average cross-correlograms (CCGs) are plotted (dots) for all 3 subjects for horizontal (blue), vertical (red), and motion-through-depth (black). The skewed-Gabor fits of those CCGs are plotted as solid lines. Here and in similar figures to follow, error clouds represent 95% confidence intervals on the data, although these error clouds are often not distinguishable from the data and/or fits. Notice the pronounced difference in tracking performance between frontoparallel motion (horizontal/vertical) and motion-through-depth.
