Control can be understood as the invisible mechanism behind everything we do; yet it's a concept psychology has almost entirely overlooked. This book introduces Perceptual Control Theory (PCT), explaining how readers actively shape their world by controlling their perceptions. The PCT framework aligns with holistic approaches and understanding of organic, self-organising systems; a paradigm shift moving psychology away from categorising disorders and towards understanding unique personal experience from a systems perspective. The book systematically explains hierarchical control systems from basic sensations to complex principles and identity. It shows why people get stuck in unhelpful patterns, how emotions signal control errors, and how reorganisation leads to change. Topics explored include, but are not limited to:- An introduction to control, perceptual control and loss of control- PCT’s model of learning and change through reorganisation, explaining how control systems modify themselves when current methods fail- How understanding of mental health difficulties may be reframed through the lens of PCT, with conditions understood as attempts to maintain control- An introduction to the Method of Levels (MOL) conversational approach applied to therapeutic practice- Scientific questions related to PCT, including its development, implications for research, addressing misconceptions and a review of supporting evidence- Practical questions and exercises inviting readers to explore their own experience of control, loss of control, reorganisation, and hierarchical perception. Authored by an expert in PCT, and based on didactive and clinical experience, this book makes PCT accessible by grounding psychological theory in daily experience. This is an essential read for clinical psychologists, psychotherapists, psychiatrists, nurses and social workers.
