    Abstract

    Twenty right-handed subjects were asked to handprint a passage containing all the letters of the alphabet once with each hand. The purpose was to describe the changes a document examiner can expect to find in handprinting done with the unaccustomed left hand and to offer a hypothesis as to why these changes occur. It was found that many of the writers displayed persistent differences between their right- and left-hand writings. It is suggested that these differences were due to both a lack of manual dexterity when writing with the unaccustomed left hand and to the fact that different neurophysiological processes are involved.
