TABLE 3.
Masked thresholds for the seven subjects of experiment 3 in backward and forward masking. Masked thresholds, as well as detection thresholds in quiet, are also shown for the four subjects who took part in the control forward masking experiment with a long masker-signal gap. Data for a given value of C (−1 or 0) are shown in plain type, with the threshold difference shown in bold type. The means and 95 % confidence intervals are shown in italics for the main experiment in the bottom two rows
