TABLE II.

Results of the 3 × 6 repeated measures ANOVAs on the magnitude of gain reduction as a function of masker type (off-frequency, on-frequency, masker absent) and elicitor duration (50, 65, 100, 200, 400, 800 ms). Both main effects of masker type and elicitor duration on gain reduction were statistically significant, however, no significant interaction between the two was found. Note that the degrees of freedom in the F-values for elicitor duration are not integers, because sphericity could not be assumed for these data. The more conservative Greenhouse-Geisser critical F-value was reported instead, which helped correct for violation of sphericity. Effect sizes for the ANOVA output are indicated by partial-eta (η²) squared values.
