CREDIBILITY ASSESSMENT OF CRIMINAL SUSPECTS THROUGH STATEMENT ANALYSIS

This paper discusses the research and theoretical underpinnings of sta tement analysis techniques for credibility assessment purposes with cr iminal suspects. Although the principles of statement analysis have lo ng been recognized, only recently have specific techniques been formal ized. It is argued that, in seeking patterns of verbal deception in th e interrogation context it is necessary to integrate theories consider ing emotional, motivational, cognitive, and linguistic factors. Approa ches emphasizing memory suggest that there exist systematic difference s between accurate and inaccurate memory accounts. Approaches emphasiz ing deception indicate that discernible differences may exist between truthful and dishonest language behaviors. Directions for future resea rch are described focussing on the need for eclectic strategies with b oth experimental and field studies.
