What is Psych-K®?
PSYCH-K® is a personal change method designed to help people shift self-limiting beliefs stored in the subconscious mind and replace them with more supportive ones.
It’s often described as a blend of neuroscience, psychology, and “whole-brain” integration techniques.

PSYCH-K® is a personal change method designed to help people shift self-limiting beliefs stored in the subconscious mind and replace them with more supportive ones.
It’s often described as a blend of neuroscience, psychology, and “whole-brain” integration techniques.
- PSYCH-K® (short for Psychological Kinesiology) uses simple processes — often involving specific body postures, affirmations, and muscle testing — to create what it calls a “whole-brain state,” where the left and right hemispheres work in sync.
- The goal is to make it easier for a new, empowering belief to be accepted by the subconscious mind, where it can influence thoughts, feelings, and behavior.
How was it developed
Created in 1988 by Rob Williams, a psychotherapist and business professional.
Williams had a background in counseling and management, and he was searching for a way to help clients change quickly and sustainably without years of traditional talk therapy.
He drew on ideas from:
- Neuro-linguistic programming (NLP)
- Kinesiology (muscle testing from applied kinesiology)
- Split-brain research on left/right brain functions
- Hypnotherapy and other mind-body approaches
His method was designed to be simple, fast, and teachable, so clients could even use some of the techniques themselves after learning them.
How does it work?
Identify the limiting belief
- Example: “I’m not good enough.”
Set the desired belief
- Example: “I am confident and capable.”
Muscle testing
- A gentle arm-resistance test is used to communicate with the subconscious, checking if the mind accepts or resists the statement.
Whole-brain integration process
- The client adopts specific body positions or movements that engage both hemispheres of the brain, allowing new beliefs to “download” more easily.
Re-test & reinforce
- The belief is re-checked via muscle testing. If it now tests strong, the new belief is considered integrated.
Action step
The client chooses a concrete action that will naturally follow from the new belief, reinforcing it in daily life.
