Table 3 SDT and SIAM detection thresholds. SDT: Mean values of the calculated detection thresholds derived from individual psychometric functions for DC EF (n = 165), DC EF with ions (n = 189), AC EF (n = 175), and hybrid EF (n = 168). SIAM: Detection thresholds were calculated from the last three reversals for DC EF (n = 134), AC EF (n = 134), and hybrid EF (n = 124). SDs are enclosed in parentheses
