For both parameters, a main effect of stimulus type was highly significant in accounting for between-condition differences—lapse rate: F (3, 390) = 9.35; p < .001; maximum sensitivity: F (3, 390) = 18.78; p < .001 ( Figures 2E and 2F )—suggesting that performance was indeed influenced by one or more of these factors in a stimulus-dependent fashion.
