The main goal is to map the ability of interrogators to register the manifestations of nonverbal communication in the situation of testimony. Secondary goal is to analyse some aspects of the process of identification of the manifestations of nonverbal communication. The research was aimed at an area that is described in the available literature sources only theoretical. This description is then only in general terms the use of non-verbal communication, and application level research practically not known. Although in reality we confirm that the file records of interrogations do not contain the part where they were described nonverbal expressions from interrogated person. This ability was tested by a presentation of short sequences of nonverbal communication on record and by denoting it on book sheet. In the analytical part of work we offer the results of our examination. This Study is a partial output of research: Methods and Procedure on crime scene - 4/2008, Vysk. 139. (C) 2013 The Authors.
