Firma auténtica y firma autofalsificada: diferencias y coincidencias en el comportamiento escrito

In recent years, the Courts, are increase their requests of forensic handwriting analysis which aims to analyze a possible auto-simulated signatures. However, research has focused mainly on the study of handwrite simulation in situations where a person intends to simulate the handwriting of another person. In this research, we study the auto-simulation of handwrite with the intention of avoiding a future legal commitment. The sample consisted of 121 individuals who perform their own signature and an auto-simulated signature. The variables of pressure, speed, legibility, and traits are analyzed. The existence of significant differences in pressure, speed and type gestures is found, being the auto-simulated signature less pressed and less rapid than the true signature and existing higher probability of occurrence of traits in the authentic one.
