1. A method for determining whether sound confusion exists between stimulus channels of a neural stimulation system comprising: sequentially applying monopolar stimulation pulses in a first order to a selected spatially-defined physical electrode pair representing adjacent stimulus channels; sequentially applying monopolar stimulation pulses in a second order to the selected spatially-defined physical electrode pair; ranking perceived sounds resulting from the stimulation pulses applied in the first order and the second order; determining whether the perceived sounds are correct, and if so, ceasing further testing involving the selected spatially-defined physical electrode pair, and if not, identifying a state of perceived confusion for the spatially-defined physical electrode pair; and using, as needed, a selected spatially-defined virtual electrode pair to more precisely define where confusion boundaries lie relative to the identified state of perceived confusion.
