Results of the loop analysis, PD, and APEP on TB and AB data. The result of the phase estimation done by using IPD method, loop analysis, and APEP on the real data. The real data was collected in a 50-subject experiment which asked the subjects to perform TB and AB. The y axis represents the phase difference measured. The significant difference of the phase difference estimated between TB and AB conditions is denoted by *p < 0.05, **p < 0.01, ***p < 0.001
