Discrimination accuracy for English listeners.

Error bars indicate standard error of the mean. Note, however, that as the statistics applied are non-parametric, they are not necessarily related to the dispersion indicated in the error bars.误差棒（error bars）表示均值的标准误。但需注意，由于所采用的统计方法为非参数统计，其结果未必与误差棒所体现的离散程度相关。
