Changing Habits of Mind: A Brain-based Theory of Psychotherapy will be published by Routledge in 2020.

We will add information on where to find the book when it becomes available.

A marvelous book, filled with clinical wisdom accumulated over almost a century of life. Zoltan brings the difference between content and process to a whole new level, bridging emotion process and personality process, thus integrating state with trace work beautifully and elegantly. He picks a sufficient amount of brain related evidence and offers a (missing) theory of emotionality, complex at first, then dazzlingly illuminating. The work of this Psychology genius still at work, is finally here to stay.

Changing Habits of Mind describes a brain-based theory of personality that provides a vocabulary for describing the dynamics of personality by integrating the mind with its body. 


The theory was inspired by Zoltan Gross’s relational, characterological-oriented psychotherapeutic practice.  The primary purpose of the book is to provide the psychotherapeutic community – practitioners, clinicians, theorists, and lay people – with a theory of personality that integrates neurobiology and psychology in a way that does not currently exist.

As the human brain evolved, it developed a prefrontal cortex which enabled us to cope with our environment more efficiently. At the same time, its complexity became a major source of psychological dysfunction.  This is why and where psychotherapy is needed.

Dr. Gross’s theory bridges the theoretical gap that has existed between the body and its mind since Plato was first puzzled by it two and a half millennia ago.

From the earliest beginnings of psychotherapy, therapists found that their clients had great difficulty changing their personalities.  Explanations, persuasion, interpretations, recalling difficulties in the past … exposure to these and other techniques have had little effect on changing the character structures that make up personality – yet the psychotherapeutic relationship does enable clients/patients to feel better, which suggests that even now psychotherapy has been missing a piece of the personality puzzle.

With the encouragement and validation of research evidence, increasing numbers of therapists – both analytic and cognitive behavioral – are understanding the importance of emotion-based therapies and the therapist’s person to successful treatment. 

The theory explained in Changing Habits of Mind describes these developments as important processes in characterologically-oriented psychotherapy.

Dr. Gross has been developing his theory for many years, sharing his findings with colleagues and refining it as it has evolved through practice, professional discourse, and continuing analysis. Changing Habits of Mind is intended to be a comprehensive guide to understanding and implementing the theory for clinicians, researchers, and lay readers.

This is indispensable reading not only in psychology but also in all of the human and behavioral sciences in which mind, thoughts, feelings, emotions, and behaviors are the subject of study. The book is a fascinating account of how a professional of human behavior came to the realization that popular conceptions of the mind are incorrect, and how he arrived at a clearer understanding of the problem.
