Psycho-linguistic study of interrogation videos: problems and possible solutions
The article examines the problems of studying the investigation video to establish credibility of the evidence, to specify emotional state, individual psychological characteristics and the psychological impact on the person being interrogated. These problems are mostly caused by the lack of a single scientifically-based methodological approach while сurrently used approaches are not developed sufficiently. We propose a fundamentally new scientifically-based psycho-linguistic approach to the study of investigation video, including the analysis of voice and sounding speech, linguistic analysis (the content and form of speech) and psychological analysis. We considered value, subject, object, and objectives of interrogation videos examination. Study of interrogation videos using the current approach is significant from the point of view of criminal law because of admissibility of evidence by the investigators. The expert concept of suggestive interrogate was operationalized on the basis of linguistic and psychological classifications.
