Percentages of orienting responses to the stimulus and mean RTs

(A) The percentages of sighted (S) and visually impaired (SVI) infants’ head and manual orienting responses, which were made toward the stimulated hand across stimulus conditions and posture conditions. In the audiotactile-incongruent condition, the data are plotted as the percentage of orienting responses directed to the auditory stimulus. Therefore, in this condition, the percentages of orienting responses directed to the tactile stimulus are 100 minus the percentage values displayed. Small circles and vertical lines respectively represent single participant means and 95% confidence intervals (i.e., ±1.96 SE) ordered with increasing ages (see Table S2). The transparent bars represent the group means.

(B) The RTs of responses to the stimulated hand. In the audiotactile-incongruent condition, the reported RTs are of responses to either the tactile or the auditory stimulus. Small circles and vertical lines respectively represent single participant means and 95% confidence intervals (i.e., ±1.96 SE). The transparent bars represent the group means. Only trials with a defined orienting response were included (see also Table S3).
