Results of Experiment 1. (A) Pearson linear correlation coefficient (r) between source distance and response distance (in log-scale) as a function of the stimulus type. Black symbols represent across-subject averages, shaded symbols show the individual subject data and bars denote standard errors. (B) Across-subject mean of the log-scale subjective distance judgments as a function of the physical distance to the source. Perfect performance is indicated by a black dashed line. (C) Across-subject average of the slopes obtained by means of least-squares linear fits between the source and the individual response distances in logarithmic scale. (D) Across-subject average of the responses' standard deviation as a function of the physical distance to the source. (E) Standard deviations collapsed over distances averaged across subjects. In (C,E) bars denote SEM.
