Normalized results in terms of DDFs. (a,b,c) Lead-discrimination performance was significantly better in the Listening experiment and in the control experiment without DS than in the Echolocation experiment and the control experiment with DS, (d,e,f) while lag-discrimination performance was significantly better in the Echolocation experiment than in all other experiments. (g,h,i) The asymmetry between lead and lag discriminations as the defining factor for the precedence effect was significantly weaker in the Echolocation experiment than in all other experiments.
