Abstract:
This study focused on interrelations between graphometric variables of the signature and measures of perception, cognitive function, and personality. Signatures from a sample of psychiatric and somatic outpatients (N = 205) were analyzed into 23 graphometric variables and correlated with tests of IQ, cognitive and perceptual function, and personality. The results of a factor analysis of the graphometric, perceptual, and cognitive variables were very much like results from previous studies. Relationships with the graphometric variables can be described in five categories of intelligence, psychomotility, flexibility and speed of closure, and personality. Graphometric signs of Extraversion and Neuroticism were identified, and the two capitals in the signature indicated different psychological meanings. Measurements of the signature offered important personality information.
