Age dependent normative data of vertical and horizontal reflexive saccades - Fig 1

Peak velocity of horizontal (direction right/left) reflexive saccades. The peak velocity (y-axis) is displayed in boxplots in dependence of the age groups (x-axis) for different target eccentricities. The whiskers extend to the minimum and maximum, when there are no outliers (displayed as circles, meaning values defined by a distance of more than 1.5 times the interquartile distance from the box). The lower boundary of the box marks the 25th percentile (25% quartile), the line within the box indicates the 50th percentile (median) and the upper boundary represents the 75th percentile (75% quartile). The arithmetic mean is shown as asterisk. In all age groups, the peak velocity increases with increasing target eccentricity.
