Handwriting characteristics and their relationship to Eysenck's extraversion-introversion and Kagan's impulsivity-reflectivity dimensions.

Examined the relationship between certain handwriting characteristics and Eysenck's Extraversion-Introversion and Kagan's Impulsivity-Reflectivity personality dimensions. Using 46 female subjects, scores on the EPQ inventory and Matching Familiar Figures test were compared by factor analysis to the handwriting characteristics of: middle zone height; middle zone breadth; upper zone height; lower zone height; space between words; right margin breadth; left margin breadth; a general size measure; handwriting time; paragraph indention; slant. The factor analysis revealed three distinct writing styles: one related to Extraversion; another related to Introversion; and a final one related to Reflectivity. These findings were discussed in relation to statements made by graphologists. Also, the significance of trait-sign and factor analysis in comparison with other methods of graphoanalysis was discussed.
