Distribution of individuation scores. Thielbar (A), normalized (B), and threshold (C) individuation scores of the thumb, index, middle, ring, and pinky fingers fall into unique ranges and have non-normal distributions. Overlapping 95% confidence intervals (shown as error bars) demonstrate the repeatability of kinematic individuation. Points represent participants’ mean individuation scores. Sample means are shown as a black dashed line. Sample medians are represented as red lines. Data from first visits are shown on the left in the graphs for each finger in the colors maroon, blue, and orange. Data from second visits are on the right in the colors cyan, green, and yellow
