Note. The analysis was conducted for the AO and AV responses of all listeners. The slope of the linear regression line describes the gain, and the intercept describes the bias of localization performance. A unity gain with zero bias indicates perfect stereo perception. In the AO condition, nonsignificant correlations (p > .05) are marked by shaded gain values. Asterisks mark the results of the exemplary listeners shown in Figure 5. AO = audio-only; AV = audio-visual.
