ABSTRACT

The examination of handwriting relies upon observation of the characteristics of the handwriting, a comparison of these features between the samples, and evaluation of the observed similarities and dissimilarities. Simulation behavior is an attempt by someone to copy another writer’s handwriting features, usually by use of a physical or mental model. This may be achieved via freehand copying, tracing, or machine generation. To better understand the production and therefore expected features of disguised and simulated writings, it can be helpful to gain understanding of how natural, normal handwriting is produced. The act of writing is a complex learned behavior that is the product of cognitive, psycho motor, and bio-mechanical processes which leave a visual trace on a writing surface. Disguised signatures may also display poorer fluency than genuine signatures due to the reduced speed of execution. Some studies report that writers typically do not alter the arrangement of their handwritten text on the page or in relation to printed baselines.
