Box plot displaying distribution of eye-voice span (# of items) across groups for the four RAN conditions. The interquartile range (IQR), between the 25th and 75th percentile, is indicated by the lower and upper boundaries of each box, respectively. The horizontal line indicates the median value. Outliers (values 1.5–3 IQRs from the end of the box) are denoted by a circle, and extreme values (values >3 IQRs from the end of the box) are marked by an asterisk.
