Gershon Ben-Shakhar is a Professor of Psychology at the Hebrew University of Jerusalem. His main area of research is Cognitive Psychophysiology and he has published about a 100 articles and book chapters mostly focusing on the role of stimulus novelty and significance in orienting response elicitation and its habituation process, and on psychophysiological detection of deception. His research on psychophysiological detection has dealt with applied issues as well as with attempts to understand the mechanism underlying differential responding to the significant information in the "Guilty Knowledge" (or "concealed information") paradigm. Recently, he is conducting a research project (with a grant from the Israel Science Foundation) on visual attention and orienting responses. This project deals with attentional selection processes in focused and divided visual attention tasks. Specifically, it examines the conditions under which stimuli outside the main focus of attention interfere with task performance and elicit orienting responses. In the past he served in several academic administration roles, as the Chairman of the Psychology Department at the Hebrew University of Jerusalem (HU), as the Dean of the Social Sciences Faculty at the HU, as the Pro Rector of the HU and as the President of the Open University of Israel.

Geert Crombez is a Professor of Health Psychology at the Psychology Department of Ghent University (Belgium). He is head of the department "Experimental-Clinical and Health Psychology". He has published more than 150 internationally peer-reviewed articles, chapters and books. His contributions have been recognized by early career awards and he has received various research grants, amongst which a 4-year FWO project in 2007 (€ 232.900), and a GOA Grant with Prof Jan de Houwer in 2006 (€ 1.400.000). He is member of the editorial board of various journals (including /Pain/ and /Psychology & Health/), and active reviewer for several journals (including /Behavioral and Brain Sciences/, /Biological Psychology/, /Journal of Abnormal Psychology/, and /Psychophysiology/), and organisations (including /The Netherlands Organisation for Scientific Research/, and the UK /Economic & Social Research Council)/. He is actively involved in experimental and applied research related to clinical psychology (anxiety and phobia), health psychology (pain) and forensic psychology (psychopathy & lie detection). His focus in these domains concerns learning, emotion, attention and self-regulation. He has successfully promoted 9 completed PhD's in these domains. He has been involved in lie detection since he was appointed by court as a member of the scientific committee to evaluate the validity and the use of the polygraph in 1991.

Matthias Gamer is a Postdoc at the Department of Systems Neuroscience at the University Medical Center in Hamburg-Eppendorf, Germany. His research is mainly devoted to forensic psychophysiology and he is especially interested in the combined measurement and analysis of parameters related to the central (EEG, fMRI) and the autonomic nervous system (SCR, Respiration, Heart Rate, etc.) during deception and information concealment. Such research is highly relevant for the identification of psychological processes that are involved in generating the physiological response pattern that is typically found in the field of forensic psychophysiology. Moreover, such a combination of multiple measures might be capable of enhancing the validity of currently applied questioning techniques.

Nurit Gronau is an Assistant Professor at the Department of Psychol-ogy at the Open University of Israel. She has conducted several studies, with Prof. Gershon Ben-Shakhar, on the efficiency and validity of polygraph assessment of guilty knowledge. Dr. Gronau examined the efficiency of behavioral measures such as reaction times in the assessment of concealed information, along with their incremental contribution to psychophysiological measures (e.g., skin conductance responses) typically used in polygraph investigations. Dr. Gronau also conducts cognitive research in the field of visual attention and visual recognition, using both behavioral and neuroimaging measures.

Sharon Leal (Sharon.leal@port.ac.uk) is a postdoctoral fellow for the International Centre for Research in Forensic Psychology, University of Portsmouth (UK). Her doctoral research focused on the central and peripheral physiology of attention and cognitive demand. Her current research focuses on the behavioural and physiological effects of cognitive load during deception. This research is very relevant for detecting how people engaging in ‘high stake' deception respond verbally, non-verbally and physiologically. Her work involves cooperation with national and international governments and police.

Ewout Meijer is a post doctoral researcher at the Faculty of Psychology and Neurosciences, Maastricht University. He received his PhD in 2008, on his dissertation entitled Psychophysiology and the detection of deception: Promises and perils. His research has focused on the use of both psychophysiological and behavioral measures in the detection of deception. Furthermore, in close cooperation with the Dutch police he is working on the practical implementation of lie detection techniques. For more information on his work, please see www.leugendetectie.nl.

Harald Merckelbach
is a full professor of psychology and the former dean of the Faculty of Psychology and Neurosciences, Maastricht University, but also holds an honorary Psychology & Law chair at the Law School of Maastricht University. He is the author of over 500 scientific papers, 37 book chapters, and 5 books. He is a member of the Koninklijke Nederlandse Academie van Wetenschappen (KNAW).

Bruno Verschuere is a Postdoctoral fellow of the Scientific Research Foundation - Flanders (FWO) at the Department of Psychology of Ghent University (Belgium). Since 2000 he conducts research on the psychophysiological detection of deception. His main focus is basic research that aims to clarify the mechanisms (e.g., orienting, inhibition) involved in detection of deception. More recent is his applied research (e.g., psychopathy, optimal test procedures, sex offenders). His research has been published in high impact journals such as Psychophysiology and Biological Psychology. Bruno Verschuere is a member of the Society for Psychophysiological Research, the European Association of Psychology and Law, and the Experimental Psychopathology Research School. He is an expert witness on polygraph testing, and provides scientific support to police polygraph testing in Belgium and The Netherlands.

Gerhard Vossel is a Professor of Experimental and Biological Psychology at the Department of Psychology of the Johannes Gutenberg University Mainz and Head of the Interdisciplinary Research Group Forensic Psychophysiology. His research focuses on human orienting response and habituation, the psychophysiology of attention and vigilance as well as the psychophysiology of interindividual differences. During the last years he systematically investigated processes involved in the detection of concealed information, relying primarily on the Guilty KnowledgeTest. This research concentrated on the role of memory processes and on the influences of emotional factors. Recent research is also concerned with the combined measurement and analysis of parameters of the central (EEG, fMRI) and the autonomous nervous system (SCR, Respiration, Heart Rate, etc.) in the psychophysiological detection of information.
