Dependent variables are the city block distance (as a measurement of localization error; columns one and two for comparisons in the single task and dual task conditions), the standard deviation (“SD”) of the city block distance for each participant (columns three and four), and reaction times (“RT;” columns five and six). Unstandardized coefficient estimates of the differences between conditions are displayed. The intercept represents the mean of values in the VIAU condition, which was tested against zero (with zero representing a perfect performance for the city block error measure).
