Sound localization in the horizontal and vertical planes. A, C, E, The left graphs illustrate the average group responses as a function of target position (and serve to illustrate the signed error relative the ideal performance, as indicated by the dashed lines) for the binaural horizontal task (A), and the monaural horizontal task (C) and vertical task (E). Note that for the monaural condition, negative angles on the abscissa correspond to the obstructed ear side, while positive angles correspond to the unobstructed ear side. B, D, F, The right graphs illustrate the average group RMS error as a function of target position, again for the binaural horizontal task (B), and the monaural horizontal task (D) and vertical task (F). For all graphs, the error bars represent the SE, and the dotted rectangles indicate a portion of space where significant group differences were observed for either the signed or RMS error. A red asterisk corresponds to a significant difference between the EBSP group and the sighted group, whereas a green asterisk corresponds to a significant difference between the EBSP and EBNP groups.

Correlation between the performance in the monaural horizontal and vertical tasks. A, B, Correlation for the horizontal positions in the far-occluded quadrant for the early blind and sighted groups, respectively. C, D, Correlation for the horizontal positions in the center-occluded quadrant for the early blind and sighted groups, respectively. Each data point represents the RMS error within the portions of space for each task. The dotted lines represent the linear trend for each group.
