This expanded new edition continues the theme of the first edition of emphasizing the ground-breaking research that examined the grammatical differences between truthful and deceptive narratives. This Psychological Narrative Analysis (PNA) is a robust program that tests truthfulness in both written and oral communications and provides clues to the communication styles and behavioral characteristics of others. PNA techniques allow people to peer into the hearts and minds of others to discover what they are thinking and evaluate the veracity of what they say. This second edition significantly updates the material in the first edition. New research in the area of detecting deception and oral communications and written statements increases annually. As the research increases, so does the need for more advanced tools to detect deception. This new text thoroughly advances the techniques previously offered. Several new chapters have been added to expand the breadth of the text. New chapters include the placement of emotions in written statements, words and phrases that signal deception, and detecting deception over the telephone. Also included in this new edition are more examples to demonstrate how the PNA techniques work and how to master them. Substantial appendices review the PNA of written and oral communications, along with practice statements for the reader, followed by a PNA of those exercises. Written in a style law enforcement professionals prefer, this book continues to serve as an authoritative and unique resource.
