A Concealed Information Test Symposium in Honor of Prof. Peter Rosenfeld

 The present symposium is dedicated to the memory of one of the world’s leading concealed information test (CIT) researchers, Prof. Peter Rosenfeld. 

Concealed information detection is a rapidly developing field of research that bears enormous potential for forensic applications. The first 2 talks will focus on different factors that may affect CIT detection efficiency: information leakage and virtual reality. As leakage typically occurs at the category level (e.g., knife, rope, gun…), the first talk (Ben-Shakhar) examines whether CIT detection efficiency is affected when questions are asked at the exemplar level (e.g., specific type of knifes). The results showed no differences in CIT effects between category and exemplar-CITs. The second talk examines whether CIT detection efficiency is affected when participants conduct a fake crime inside a novel virtual reality scenario (Suchotzki). The results showed significant CIT effects with three autonomic measures, which were somewhat smaller than those observed in regular mock-crimes. 

The third and fourth talks will focus on brain-based CITs, which was Prof. Rosenfeld’s specialty. The third talk (klein Selle) will provide a review of the existing brain-based CIT literature: it will explain the different brain-based measures, their validity and theory. It will also present several exiting future developments which could potentially ease the real-world application of brain-based measures. The fourth and final talk (Matsuda) will review a series of brain-based CIT studies which manipulated the intention to conceal. The results showed that the motivation to conceal induces a frontal negative slow wave, approximately 500–1000 ms after item onset.
