Pitch and loudness interactions comparing stimulation of a cochlear array site alone with a combination of stimulation of that site with the interleaved stimulation of the distalmost site on lateral canal array at threshold for perceived motion in VI07. Both graphs plot individual perceptual judgments fit by a second-order polynomial and bounded by the 95% confidence interval of the fit. a Normalized perceived pitch differences between cochlear stimulation alone and cochlear stimulation with interleaved vestibular array stimulation. Positive values indicate an increase in perceived pitch with combined stimulation, and negative values indicate a decrease. b Normalized perceived loudness differences between cochlear stimulation alone and cochlear stimulation with interleaved vestibular array stimulation. Positive values indicate an increase in perceived loudness with combined stimulation, and negative values indicate a decrease. Electrode number on the cochlear array is indicated by the values on the abscissa of each graph. A value of 1.0 on the ordinate of either graph corresponds to the maximum difference for a given measure between any two electrodes on the cochlear array for subject VI07.
