Spatial Accuracy differences between 2D-GRIDS and 3D-GRIDS.

<p>Spatial Accuracy refers to the mean distances between the original and recalled places of interest (POIs). The recall of a POI was considered as correct if the recall location fell within a linear distance of 0–40.27 px (0–1 cm). Error bars represent the standard error of the mean. ** = p <. 01.
