Chapter 1 - The physiology of writing

Abstract

This chapter describes the actual act of writing and those factors that collectively are relied upon by Forensic Document Examiners to determine the identity of the writer. It also deals with how the writer holds the writing instrument, the act of writing or movement of the writing instrument using the fingers, hand, wrist, and arm. The results of these movements, as recorded in the writing, can disclose the habits of the writer if the movements are natural for that writer, or if the writer is altering their normal writing.
