Guanqing Wang · Forensic Science and Criminology · 2019
The testimony of handwriting identification is more uncertain than other kinds of physical evidence identification.If the expert did not employ the principles and methodologies based on neurophysiology, the examination would not be sufficient, and the testimony might be suspect.This research describes how neurophysiology influences the feature of handwriting and the methodology of identification: most handwriting characteristics have high-level individualization determined by the nervous system.The methods of defining the characteristics of handwriting were explored and it was found that writing motion rules and writing norms are effective measures to compare and match writing characteristics.Additionally, the number of characteristics and their degree of individualization are the bases to assess the handwriting characteristics system, quantitatively and qualitatively.Practical cases have been presented to support the theories proposed.
