Actors have traditionally been trained using techniques rooted in 19th-century psychology, but acting teacher and researcher David Ihrig argues these outdated methods no longer reflect how human behavior actually works. In his new book "The Actor's Algorithm: Seven Brain-Based Steps to Embody Character", Ihrig presents a modern, neuroscience-based approach to acting that shows performers how to build character-specific memories, form driving beliefs, and respond organically to imaginary stimuli.

Why it matters

Ihrig's method aims to empower actors by giving them a clear, scientific understanding of how to authentically inhabit a role, rather than relying on abstract advice. By aligning acting with modern brain science, the book provides a usable system that actors can apply immediately to their craft, potentially leading to more genuine and impactful performances.

The details

"The Actor's Algorithm" outlines a seven-step process that includes brain-based script analysis, memory induction, emotion encoding, directed focus, and embodied self-assessment. This allows actors to create character-specific memories and beliefs, and respond organically to imaginary stimuli. Unlike many acting books, Ihrig's method is heavily researched and supported by a full bibliography, and each chapter includes downloadable worksheets and guided audio exercises for practical application.

  • The book "The Actor's Algorithm: Seven Brain-Based Steps to Embody Character" was published on February 18, 2026.

What they’re saying

“The Actor's Algorithm" aligns the craft of acting with modern brain science, reframing performance as a process driven by attention, memory, belief, and sensory experience.”

— David Ihrig, Acting teacher and researcher (PRNewswire)

“That great acting isn't mysterious—it's a skill. When you use your brain the right way and invest the time and effort required to create a role, authentic performance becomes inevitable.”

— David Ihrig, Acting teacher and researcher (PRNewswire)

What’s next

The book "The Actor's Algorithm: Seven Brain-Based Steps to Embody Character" is available for purchase on Amazon and Barnes & Noble.

The takeaway

By grounding acting in modern neuroscience, Ihrig's "The Actor's Algorithm" provides actors with a clear, scientific framework to build more authentic and impactful performances, potentially transforming the way acting is taught and practiced.
