The Department of Criminalistics at the Faculty of Law and Administration of the University of Silesia in Katowice has been studying the polygraph examinations for exactly 30 years now. The Department has conducted many scientific studies in this area and the staff have also provided expert opinions for use by law enforcement agencies. The purpose of this article is to present the problems our staff currently encounter in working with the polygraph within Polish criminal procedures and to present practical examples illustrating some selected problems. The article begins with a brief description of the history of the polygraph examinations in the Department. Studies on polygraph examinations in the Department of Criminalistics at the University of Silesia began in 1977 when Jan Widacki joined the Department and brought with him the first polygraph equipment from the Jagiellonian University in Krakow. The device was first hired and then donated to the Department (today,

The issue of psychophysiological examinations utilizing polygraph causes many discussions for scientific and social reasons. usually, this is connected with limited access to knowledge in this area and consequently – common beliefs operating in Polish public opinion. The article presents the results of a survey, including such variables as: knowledge of the concept of polygraph examination, experience in using this method, opinions about practical application of polygraph examinations (both during recruitment and at the stage of employment in specific positions or in criminal proceedings). The results indicate a miserly range of knowledge about such examinations in the society, largely based on an inadequate or insufficient presentation of this method in the media, press and literature (also covering specialist issues). These perceptions were correlated to the actual utility of polygraph examinations in different fields of practice – particularly in public institutions (uniformed se...

I obtained my fi rst expert knowledge of polygraph from a course book of criminalistics by Paweł Horoszowski published Poland in 1958. Th e author provided his descriptions of the polygraph and examinations with an ideological commentary (among other things like this: "lie-detector is an imperialistic tool of torture"). Having returned from the US, where he held a scholarship from Ford Foundation and purchased a Stoelting polygraph device, Horoszowski changed his opinion and now considered polygraph examinations useful for criminal cases, and began to perform polygraph examinations in criminal procedures himself.

The authors of this article consider the advantages of using a visual version of CIT during polygraph examinations. The presentation of the rarely used CIT encourages to discussion about the possibility of implementation such tests in serious criminal cases. Their application takes a form similar to the police lineup. However, the main difference is that the suspect reviews photographs of possible crime victim. In the described case we are dealing with a so-called “reverse police lineup”. As the result, the visual CIT proved that the examinee knew the victim of the crime, despite the fact that he had previously denied this. Thanks to the examinee’s arousal recorded on the key question, it was also possible to obtain the desired psychological effect in the form of the perpetrator’s confession and the indication of other evidence proving his guilt.

In our last article we mentioned that in Lithuania the event knowledge test (EKT) is widely available (Saldziunas and Kovalenko 2008 ). Recently we made a psychophysiological test by polygraph which revealed the important circumstances of a crime, helping the police to investigate it. In September 2007 in a Lithuanian city a 29 year-old car salesman disappeared in mysterious circumstances after meeting a friend. After a few days the missing businessman P.’s car was found. His disappearance met with a large response in the community. Police looked over various versions and checked the evidence of witnesses and other participants in the criminal trial. They also conducted a detailed verification of this evidence and investigated objects or inspections. For instance there was rock oil and biological analysis. They analyzed businessman P.’s way of life. Police officers worked extremely hard, almost without days off. Finally they came to the conclusion that P. was dead, and accordingly
