Results from Experiment 1. For each experimental condition (S–D, Synchronous – Displacement; S–ND, Synchronous – No Displacement; A–D, Asynchronous – Displacement; A–ND, Asynchronous – No Displacement) and for both the Pre- and Post-test, the proportion of judgements that the distance between dual tactile stimuli on the right arm felt greater than on the forehead was analyzed as a function of the ratio of the length of the arm and forehead stimuli (i.e., 4/6, 5/6, 1, 6/5, or 6/4). Curves are cumulative Gaussian function fits to the group data, for each condition, with least-squared regression. Error bars indicate the SEM. Vertical lines indicate the interpolated points of subjective equality (PSE) between the perceived distance on the arm and on the forehead. Red asterisks denote a significant change in PSE from Pre- to Post-test (∗∗∗denotes p < 0.001, corrected for multiple comparisons). Note that an increase in the PSE meant that perceived tactile distances on the arm were felt smaller, as compared to distances on a reference location.
