SPEAKish allows us an insight in the new paradigm of communication. SPEAKish explains how our brain operates especially during the decision making process, conflict and stress.

Written from the viewpoint of an ardent observer of human behavior, most material in this book is common sense combined with results of recent scientific research. The threshold is accessible for anyone who recognizes this importance of these developments.

Professionals can increase the level of mutual understanding and communicate using less words and more SPEAKish .
