Shelley Roy provides a lively analogy to introduce the basic ideas underpinning the scientific theory of living systems; Perceptual Control Theory. Focusing on the difference between 'the rock view' of life and 'the plant view of life, Ms. Roy explains how to date much of the thinking on human behavior is based on two faulty theories; stimulus response psychology and cognitive psychology. These theories which Ms Roy refers to as 'the rock views' lead to thinking that with the right strategy, the right program, the right language anyone can learn to control someone else. Shelley also shares her belief that "one size does not fit all" and that customization is necessary to better meet the needs of individual clients.
