Route-Finding Performance.

<p>The bar plots show trial-by-trial times for individual subjects in the three groups when they used the tag reader (lower panels) or did not use the tag reader (upper panels). Yellow bars designate outliers. Two box plots at the right show the distributions of the times-to-completion for the three groups of subjects in terms of the median times (red lines), 25% and 75% quartile limits (blue boxes), the maximum and minimum values (whiskers), and outliers (red crosses) for the three groups. Upper and lower dash lines, when present, mark the preset range limits if any outliers are outside the limits. Separate box plots show times for testing with and without the tag reader. A third box plot shows the within-subjects difference in times-to-completion with and without the tag reader.
