At the end of the previous chapter we presented a dynamic systems model that considered the ®t between resources and challenges as being necessary for development. A ``pool of resources'' that might apply to a young person's choice of deception or truth as a communication strategy was then developed. This ``resource pool'' was also linked to their likely success at deceit. In this chapter, we present some examples of each type of resource which have been chosen to provide the reader with some of the most salient in¯uences on adolescent communication. These are divided into the ®ve categories presented at the end of Chapter 1.
