About the Book

Clear. Grounded. Revolutionary.
The Actor’s Algorithm transforms how actors train and perform by integrating discoveries from neuroscience into every step of the craft.

Most acting books rely on outdated methods and metaphors that can leave performers confused. This book breaks the mold by introducing a practical, brain-based system that demystifies behavior, memory, and performance.

In this book, you’ll learn how to:

  • Create real, character-specific memories using neuroscience-based memory induction techniques.
  • Translate complex emotional cues into specific behaviors using the theory of constructed emotion.
  • Use brain-based script analysis to decode what your character truly means—not just what they say.
  • Prepare for scenes more effectively using step-by-step cognitive techniques rooted in how the brain works.
  • Speak confidently about your craft—without falling back on outdated language or abstract acting jargon.

Whether you’re a student actor, a working professional, or an acting teacher, this book gives you a clear system that reflects how people actually think, feel, and behave—on stage and in life.

About the Author

David Ihrig is an actor and a teacher who offers a systematic approach to acting using principles from the cognitive, psychological, and neurobiological disciplines. As an adjunct professor of drama at the University of California Irvine, he designed the university’s first interdisciplinary course on the science of acting. He’s a founding member of The Artistic Brain, a theme of the UCI Brain Initiative, one of the country’s only brain initiatives devoting resources to an artistic theme. He most recently established the Irvine Theater Company, which integrates the brain-based model into all aspects of dramatic creativity while incorporating technology to enhance the audience experience. Lastly, he plays sand volleyball and drinks tequila every Wednesday in a weekly ritual that spans over twenty-five years.

QUOTES FROM EXPERTS
Emotion and behavior both emanate from the brain and The Actor's Algorithm shows readers how to activate key parts of the brain to produce authentic responses on stage and on film. The brain-based techniques in this book are the update acting has needed and are sure to make learning the craft of acting faster and easier.

David Ihrig’s new book provides a novel, engaging and compelling approach to the teaching (and learning) of acting based on psychological and neuroscience findings. As acting is “pretending” to be someone, having or creating a rich understanding of a real or imaginary character, he proposes, is essential. Acting is, of course, much more than learning lines and movements, he argues cogently. As the character is more “fully” created, the dialogue and actions become “natural” outcomes. A refreshing perspective on an ancient endeavor.

In the diverse landscape of today’s acting training, 'The Actor’s Algorithm' emerges as a crucial update to traditional methodologies. Current training often relies on age-old techniques that don’t fully tap into the actor’s cognitive and emotional capacities as understood through modern science. David Ihrig’s brain-based approach fills this gap by integrating the latest advancements in neuroscience, offering actors a scientifically grounded method to enhance their craft. This book challenges the conventional reliance on intuitive methods by providing a structured, brain-aware framework that leads to more precise and emotionally resonant performances. In an era where authenticity on stage and screen is more prized than ever, Ihrig’s method equips actors with the tools to deliver deeply authentic, engaging performances that resonate with contemporary audiences. 'The Actor’s Algorithm' isn’t just a book—it's a transformational tool that redefines the boundaries of acting training in the digital age.
