What is said is not always meant. What a conversation partner really means and how they are feeling at the moment is often inferred from their body language and physical expression. Vigorous nodding and a beaming smile indicate enthusiastic agreement. In contrast, a laugh that doesn't involve the eyes is immediately recognized as "false." How do we actually know this? Are we always correct in our interpretations? This book invites readers on a journey of discovery into the world of body expression: With numerous suggestions for observation and experimentation, readers can sharpen their perception and test new forms of expression themselves.
