Ten-position localization in three trained participants. A subject was asked to identify the position of an ~30 cm plastic plate held at 1 m distance, (a) Schematic illustration of the 10 possible configurations of the plate, including nine spatial locations and a tenth “absent” condition, (b) Summary of fraction correct for the 3 subjects, for exact identification, and for identification of absent/present, horizontal position, and vertical position. (c) Spatially arranged confusion matrix of behavioral results for Subject 1. Each sub-figure corresponds to a location of the plate, and the intensity map within each sub-figure indicates the fraction of trials the subject reported each position for each plate location. Black corresponds to a subject never indicating a location, and white corresponds to a location always being indicated. Each sub-figure sums to 1. (d) Confusion matrix grouped into plate absent and present conditions for Subject 1. (e) Confusion matrix grouped by horizontal position of the plate for Subject 1. (f) Confusion matrix grouped by vertical position of the plate for Subject 1. (g-j) Same as in c-f, but for Subject 2. (k-n) Same as in c-f, but for Subject 3.
