ABSTRACT
The detection of deception and the assessment of credibility are crucial aspects of practitioner work in the forensic domain and in our interactions in everyday life. Although we move our focus here to the detection of adolescents' lies, what we are interested in is the interpretation of different types of interpersonal communication through the implementation of a holistic and bespoke approach. The holistic element we refer to here involves consideration of the range of factors that leads to the young person's choice to engage in deception and by their very nature are multifaceted. Hence we have moved away from a piecemeal approach where only certain elements of communication are considered and are drawn instead on a multitude of issues. This is in part because, as we have argued earlier, detection as with the choice to engage in deception is concerned with the communication context and the variety of resources presented in Chapter 2. Therefore in line with our approach to understanding and interpreting deception in adolescence, we will not be suggesting speci®c verbal or non-verbal cues to look out for. We further propose that it is crucial for the identi®cation of deception to be developed via a thorough understanding of the individual being assessed. This requires a broader and deeper perspective than mere behavioural movements or speech utterances considered in isolation of a larger picture. This re¯ects emerging evidence from, for example, the use of the process of sketching locations as a technique for detecting deception (e.g. Vrij, Leal, Mann, Warmelink, Granhag, & Fisher, 2010; Vrij, Mann, Leal, & Fisher, 2010) where a crucial aspect seems to be the triangulation of information across multiple forms of presentation.
