What are we talking about?

An introduction to the Acceptance & Commitment Therapy (ACT)

Neuroscience and Acceptance & Commitment Therapy (ACT) are related in the sense that both deal with how humans think, feel, and behave - but they do so from different levels of analysis. While neuroscience focuses on how the brain functions, ACT helps people relate differently to their thoughts and emotions through acceptance, mindfulness, and values-based action. And its impact has been measured with neuroscience – hence the link! And these findings provide biological evidence that ACT doesn’t just change thoughts or feelings, but changes brain function and connectivity.

As an example, S.A. Aytur et al. (2021) conducted a study called “Neural Mechanisms of Acceptance and Commitment Therapy”. They found that after ACT, participants showed improved function across large-scale brain networks: the default mode network (DMN), salience network (SN) and frontoparietal network (FPN). Or measures done by S.W. Lee et al. (2024) showed the impact of ACT on obsessive-compulsive disorder: his study found significant changes in brain activation and connectivity.

But let’s go back to ACT and what it is.

How are these concepts reflected in THEe PUZZLE?

Positive Psycology can be found in the following Puzzle pieces: Myself is multiple, Protecting myself, My Filter, Connecting to Myself, The Universal Rule and My Compass.

  • You will find in THEe PUZZLE the notion of incongruence; meaning the gap between who we think we are (self-concept) and who we truly are (our authentic self). With the intent to reach congruence and align both to live better. These notions are for instance part of THEe PUZZLE pieces “Myself is multiple” or “My Filter”.

  • With self-coaching, the notion of feeling accepted and valued without judgment is paramount. Starting with our own self, and also to learn to set limits with others. This is represented in being “Present”, “My Compass” and “Connect”.

  • The concept of fully functioning persons (ie connected to their emotions, living in the present, lucid in their decision making, free to choose, create and grow) is fully embedded in THEe PUZZLE, and highlighted in particular in “My Filter”. 

  • The Broaden-and-Build Theory of Positive emotions is part of our Tips & Tricks, as well as in most use case stories. Typically the fact that as you connect and build upon positive emotions, your mind opens up and you can access inner resourcessuch as resilience or optimism. This can for instance be found in “My Compass” and “The Protection in my head”. 

Useful books to read

The Power of Habit

by Charles Duhigg,

Thinking, Fast and Slow by Daniel Kahneman

while not strictly behaviourism, this book deals with decision-making, behaviour, biases, and is very useful when bridging behaviour change, work behaviour, relationships.

Science and Human Behavior (1953, B.F. Skinner)

comprehensive statement of his behavioural theory.

About Behaviorism by B. F. Skinner

his is a classic work by one of the leading behaviourists
