Abstract

In this paper, an attempt was made to study variations in writings of an individual with variation and temperature. The primary data for this study was taken from males and females under varying temperature conditions which is 3–7°C in morning before 9 a.m. and 15–20°C in the afternoon around 2 p.m. The samples taken in cold and normal temperature were compared, a definite variation in the handwriting was observed, which can be classified under natural variations. The individual characteristics in such cases somehow remained reliable.
