Manifestation of neuroticism in handwriting

Variability of the amplitude of manual movements in handwriting has been studied in junior youth subjects with low and high level of neuroticism. The variability is found to be significantly higher in "neurotic" subjects as compared with "stable" ones, which proves the hypothesis of correlation between the level of neuroticism and the swing of graphical movements.
