This article discusses the research and theoretical underpinnings of statement analysis techniques for credibility assessment of criminal suspects.
Abstract
Although the principles of statement analysis have long been recognized, only recently have specific techniques been formalized. This paper formulates the hypothesis that there are systematic differences between the accounts of honest and deceptive suspects in the interrogation context. The study considers one theoretical bent founded on memory accuracy and a second theoretical perspective which underscores the betrayal of deception in language due to affective and cognitive factors. The paper argues that, in seeking patterns of verbal deception in the interrogation context, one must integrate theories considering emotional, motivational, cognitive and linguistic factors. Approaches emphasizing deception indicate that there may be discernible differences between truthful and dishonest language behaviors. The article describes directions for future research focusing on the need for eclectic strategies with both experimental and field studies. References
