Early attentive processing on forged and genuine exemplars by imitators: An ERP study.

Important questions have arisen about the capacity of traditional questioned document methodology to differentiate between genuine and forged exemplars of an author's handwriting. This paper does not address that dispute. The paper describes the first part of a research project investigating whether imitators (forgers) can reliably differentiate between genuine samples and forgeries. This paper takes a different, cognitive neuroscience approach and investigates the overlooked topic of the mental processing of forgeries by forgers. The paper tried to examine the neural mechanisms of imitators' (forgers') attentive processing of forged and genuine exemplars. The data in this initial phase of the study showed imitators experienced more difficulty evaluating their own forgeries perhaps because the forgeries included both the features they had consciously copied and some of their own handwriting characteristics that they could not completely suppress. A subsequent phase of the study will use self-reporting and eye movement tracking studies, in this phase we shall attempt to identify the specific types of features the imitators relied on in correctly classifying the exhibit as a forgery. We shall then enlist the services of experienced questioned document examiners endeavor to determine whether those characteristics appear in genuine exemplars of the forgers' handwriting. The identification of those categories of features may hold the potential for improving both the detection of forgeries and the identification of the forger. [ABSTRACT FROM AUTHOR]
