The Human Experience Framework: Developmental Guide

The Human Experience Framework: Developmental Guide

How a child's nervous system develops, and how a parent's nervous system shapes it.

Most descriptions of psychological struggle are about now: current symptoms, current severity. Where the pattern came from is treated as background and set aside. This guide is about where it came from.

A developing brain does not store experiences to replay later. It forms expectations about what the world is like, and expectations, unlike stored records, can be updated. Nothing here is fixed, and everything here can be worked with.

The guide is written for parents, and for the clinicians and educators who support them. It covers:

• how a child's nervous system develops, and why timing matters

• temperament, and how well a child fits their environment

• what a child's body may be signalling, and how to respond

• how a parent's own patterns shape the home; rupture and repair

• how two parents' patterns combine into one home

• the sixteen patterns, and what each typically needs in childhood

• adolescence, when to seek help, and special circumstances: foster care, divorce, grief, a parent's illness

• practices by age, from infancy to 18, and a self-reflection appendix with no score

The guide centres on the conditions that shape a pattern and on what protects against them: calibration, not blame. It draws on the Human Experience Framework and on established research in neuroscience and developmental psychology. The full clinical reference is free (below).

This material is for education and reflection. It is not medical, psychological or psychiatric advice, and it is not a diagnostic tool. It supplements professional support and does not replace it. If you or your child may be in immediate danger, contact local emergency services; in the U.S., call or text 988, the 988 Suicide & Crisis Lifeline.

Revised October 26, 2026. This revision describes each parent by the pattern they live in, never by a label. It names the third appendix, practices by age, in How to Use This Guide. It moves one research citation to the section it belongs in.

About the author: Justin Joseph DeGarbo, Founder and Clinical Director of Cathexis Health.

Cathexis is one body of work in five parts. The map is free: The Human Experience System (the theory), The Human Experience Framework (the clinical classification) and the Cathexis Somatic Ontology (the same architecture, machine-readable). The Practitioner Manual trains clinicians to use the map in the room. The Developmental Guide applies the map to how a person learns what to expect, from childhood on. The Cathexis app is where a person works with their own pattern in their daily life, on the same map a clinician uses (cathexis.health).
