Table 1.

The number of sessions in illusion and nonillusion set. “I” means that the participant answered (Q1) + (Q2) ≥ 10 after the session in synchronous condition, and “N” means that the participant answered (Q1) + (Q2) ≤ 6 in asynchronous condition. We got 30 sessions where participants experienced the illusion and 31 sessions where participants did not experience the illusion at all and defined those sessions as illusion set and nonillusion set.
