Difference of IPD from both test and retest as a function of averaged IPD of both tests for every participant (Panel A: active stop distance task; Panel B: passive stop distance task) with mean difference (black line).
Fig 3.
Mean preferred interpersonal distance as a function of Block.
Error bars denote +/- one standard error of the mean.

Mean discomfort ratings as a function of interpersonal distance (IPD) separately for each block, aggregated across subjects.
Lines denote the different methods of assessment for discomfort applied in the three blocks.
