Motor Awareness judgments. (a) MA as a function of delay. ND corresponds to non-delayed trials, HD to a mismatch of a half-cycle step, and FD to a full step cycle. The vertical line indicates the average single step and full step-cycle, with their standard deviation underlaid in grey. The cosine function (dashed line) confirms the regularity of MA modulation (y-axis) as a function of the delay (x-axis). Black circles show the population’s mean MA ratings. Participants self-attributed the majority of trials for temporally synchronous feedback (ND, FD). MA judgments decreased with increasing delays until 600ms, which correspond to a half-step cycle delay. At HD trials, participants receive tactile feedback left-right reversed, resulting in the lowest self-attribution ratings. The boxplot of MA judgment across delays (median ± 1.5 interquartile range whiskers, 25th to 75th percentile range, and outliers). Boxplots indicate higher intersubjective variabilities for trials that are neither temporally nor spatially congruent. (b) Temporal thresholds were determined by fitting a cumulative Gaussian (cf. Data Analysis). The temporal threshold for remapped tactile walking agency was estimated as 378ms
