The Actor's Algorithm: A Brain-Based Approach to Actor Preparation



Developed through years of actor training, collaboration with cognitive scientists, academic case studies, and real-world production work, The Actor’s Algorithm offers actors a clear, seven-step process for creating authentic performance.

Acting Has Changed. Actor Preparation Hasn't Changed Much.

Today's actors face new challenges:

Today's actors often work under conditions that previous generations rarely encountered. Shorter preparation timelines, limited rehearsal opportunities, self-tape deadlines, and the growing use of virtual production environments require actors to prepare quickly while still delivering authentic and compelling performances.

At the same time, our understanding of memory, attention, emotion, and human behavior has evolved dramatically over the last several decades.

The Actor's Algorithm was developed to bridge these two realities by integrating contemporary insights into a practical preparation process designed for the demands of today's actors.

Performance Emerges from Preparation

Rather than attempting to directly control emotion during performance, actors use the process to build the internal conditions that support authentic emergent behavior.



The work focuses on:


  • perspective 
  • memory 
  • attention 
  • belief 
  • stimulus 
  • imagined experience 


The goal is to avoid mechanical acting.


The goal is preparation that allows performance to be more connected, adaptable, and alive.


The 7 Steps

Intro to the Actor's Algorithm

The Actor’s Algorithm is supported by guided worksheets and audio memory inductions that help actors apply each step directly to auditions, scene work, and character preparation. Together, these tools create a practical and repeatable process actors can use throughout their careers.

Step #1- Brain-based Script Analysis

Actors engage in a comprehensive research process designed to help them understand the character’s behavior from the inside out. Actors begin by identifying important differences between their own meanings and the character’s meanings, then use a technique called reframing to adopt those character meanings themselves. This process establishes the granular units of meaning that become the building blocks for the character’s inner world, behavior, and experience throughout the story.

Step #2 - The Driving Belief

Actors identify and embody the character’s core belief system. As actors adopt the character’s beliefs, they begin experiencing the world through the meanings, assumptions, and expectations of the character rather than their own. This essential step happens early in the process so the actor’s entire discovery process becomes framed through the character’s unique worldview.

Step #3 - Scripted Memories

Instead of skipping over or taking for granted the past experiences provided within the script, actors use those moments to create vivid memories for the character. By mentally experiencing those events as lived experiences, actors gain access to some of the most emotionally meaningful and visceral information available within the story. Because these experiences originate directly from the writer, they often provide some of the clearest insight into the world of the play and the writer’s original intentions for the character.

Step #4 - Scene Memories

In this step, actors identify and embody the most relevant information surrounding the situation of each scene. Actors create memories around the three primary elements of drama—environment, relationship, and mood—which help the brain establish meaning, context, and emotional significance within the story world. This process deepens the actor’s understanding of how the character feels about the environment, the other characters within the scene, and the emotional circumstances present at the beginning of each moment.

Step #5 - Mapping the Environment

Actors mentally construct the physical environment of each scene so the world of the story becomes more vivid and experientially real within the imagination. This process prepares the brain to place attention naturally on the people, objects, and events surrounding the character during scene work.

Step #6 - Directed Focus

For the first time in the process, actors begin working directly with the dialogue. After spending the earlier steps preparing the character’s meanings, beliefs, memories, relationships, and imagined environment, actors break the script into units of attention called beats. Each beat is then assigned a specific stimulus—something the character sees, hears, feels, or says internally to themselves.


Rather than deciding intellectually how a line should be delivered, actors use directed focus to place attention on meaningful stimuli within the imagined circumstances of the scene. This preparation process allows dialogue, emotion, and behavior to emerge more naturally from the actor’s lived experience within the imagined world of the story, giving actors a natural connection to the words.

Step #7 - Self-Assess your Preparation

Actors engage in run-throughs of the scene while observing bodily sensations and internal responses in order to assess how fully the preparation process has been embodied.

UCI hosted a collaboration between the Center for the Neurobiology of Learning & Memory and the Claire Trevor School of the Arts, in which researchers shared current knowledge of the brain systems that regulate human behavior.

The Irvine Theater Company uses The Actor's Algorithm as the creative engine for the entire company. The attention based model has been reverse engineered so that writers use the process to create new works.

University Workshops

Actor Training Programs

In 2017, a workshop was held for four upperclassmen in well-known local theater programs to see how they would react to the new model after having been immersed in the traditional models taught at their schools.

Biometric Case Studies

Biometric measurement system created by Paul Zak's company named Immersion Neuroscience used in several studies to measure real time brain response in actors.

Cal Poly's Advanced Acting Class did a direct comparison between the traditional action-based model and the attention-based model. Students wore biometric devices and captured real time brain activity while exploring acting techniques. Several independent studies implemented the technology at UCI as well.

Private Coaching

Acting Classrooms

The Actor's Algorithm has proven an efficient preparation process for on-camera and live auditions. Private coaching is available online for actors living outside of the Southern California area.

The brain-based model was first tested at high-school summer camp. Since then it has been presented to students in local high schools, universities, and a number of students in independent studies at UCI.

Developed Through Interdisciplinary Exploration

The development of the process includes ongoing conversations and collaborations involving acting, cognition, memory, emotion, and human behavior.


The approach has been explored through university-affiliated projects and workshops investigating the relationship between performance and contemporary understandings of the brain.

Experience the Process for Yourself

Whether you are an experienced actor looking to deepen your work or someone searching for a clearer approach to preparation, The Actor’s Algorithm offers a structured process designed to help actors approach performance with greater clarity, freedom, and confidence in their craft. You are invited to experience Step #2 of the process for yourself.
