“…For example, SJ tasks use an index calculated based on the temporal distribution of the simultaneous response rate (usually a bell‐shaped Gaussian curve). Indexes include: (1) the interval between the two SOA values corresponding to a 75% simultaneous response rate (Marsicano et al., 2022 ; Venskus et al., 2021 ; Zerr et al., 2019 ); (2) the interval between the SOA value corresponding to the point of subjective simultaneity and the SOA value corresponding to a 75% simultaneous response rate (just noticeable difference, JND) (Christie et al., 2019 ; Li et al., 2021 ); (3) half of the interval between the two SOA values corresponding to a 50% simultaneous response rate ( δ ) (Chen et al., 2018 , 2021 ); (4) the standard deviation of the distribution (SD or σ ) (Yarrow et al., 2016 ; Zampini et al., 2005 ); (5) the interval between the two SOA values corresponding to 50% of the maximum rate (full width at half height, FWHH) (Alm & Behne, 2014 ; Roseboom & Arnold, 2011 ; Roseboom et al., 2009 ); and (6) half of the interval between the two SOA values corresponding to 50% of the maximum rate (half width at half height, HWHH) (Fujisaki & Nishida, 2009 ). The larger these values, the larger the TBW, resulting in a lower temporal resolution of synchrony perception.…”
