Yes. It is in that community where the sub stratum for a life of sobriety is incorporated into daily life and becomes new behaviors. Where the neural connections within the prefrontal cortex are further strengthened and not allowed to pare away. In other words, the aftercare community of practice is where habitation is formed, becoming the clients' new steady state of living... where the concept of homeostasis is applied to everyday life. See William James book on psychology for the physiological implications of habituation, and Cozolino on the Neuroscience of Psychotherapy.
Wow!! Thank you so much for your time and trouble Ian and Colette. Your responses have been most helpful. Colette I am thrilled with the connection between Community of Practice and neuroscience. It makes a massive link for me.
According to Etienne Wenger, the answer is a big yes.
Here's the definition of a community of practice: “a group of people who share a concern, a set of problems, or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis”, (Wenger, 2002)
