Abstract

The purpose of this study is to find out if there are any differences between sinistral and dextral individuals as well as differences in gender based on their handwriting characteristics which will help in identifying the author in case of anonymous letters or any other document whose author is unknown. This study was conducted on 25 left-handed males, 25 left-handed females, 25 right-handed males and 25 right-handed females. A control passage was dictated to the subjects and they had to write it twice, in their own handwriting, on the two blank sheets provided. The characteristics of the handwriting were analyzed. According to the findings of this study, the horizontal strokes of the numbers “1”, “5”, “7”; the letters “A”, “E”, “F”, “H”, “I”, “J”, “T”, “f”, “t” and the Hyphen (-) executed from the right to the left direction and the circular strokes of the numbers “9”, “0” and the letters “O”, “Q” and “o” executed in the clockwise direction indicate that the character has most likely been executed by a left-handed individual while the horizontal strokes executed from the left to the right direction and the circular strokes executed in the anti-clockwise direction indicate that the character has most likely been executed by a right-handed individual.
