The use of body language (behaviour pattern recognition) in forensic interviewing

Abstract

With this study, the researcher wants to establish whether investigators are able to effectively interpret, report on, or pay cognisance to body language during interviews, and whether they are sufficiently trained therein. Knowledge of body language can provide the interviewer with vital clues during the interview process. Regardless of the availability of numerous literatures on nonverbal behaviour in interviewing, the application of this knowledge is lacking among investigators. An empirical research design and a qualitative research approach were used for this research. National and international literature sources were consulted, and the researcher conducted interviews with two experts, knowledgeable investigators and semi-structured interviews with detectives from the East London South African Police Service (SAPS) and forensic investigators from the Special Investigating Unit (SIU) in East London. The importance of the skill of interpreting body language during forensic interviewing was established. Evidently, many investigators do not apply their knowledge and skill to enhance the outcomes of a forensic interview.
