Two influential thinkers — Freud and Erikson — each tried to map out the stages of human development. Neither is the complete picture, but together they offer a language for understanding how your early experiences may still be shaping how you feel and relate today.
A note before you read
Freud's ideas — useful, but not the whole story
Sigmund Freud was a pioneer who first suggested that our childhood experiences shape our adult inner life. Many of his ideas have since been updated or challenged, and some — particularly around gender — are considered outdated today. What remains valuable is the central insight: that early emotional experiences leave an impression, and that those impressions can show up in our adult relationships, patterns, and feelings. Your therapist may draw on these ideas gently, as one lens among many.
About this model
Erikson's eight stages of life
Erik Erikson built on Freud's work but extended it across the whole of life — not just childhood. He believed that at each stage, we face a central challenge or "crisis." How we navigate that challenge shapes our sense of self, our relationships, and our confidence. Importantly, he believed these challenges can be revisited and healed — which is partly what therapy is for. Click on any step on the staircase, or use the buttons, to explore each stage.

Sigmund Freud
The unconscious architect
Freud believed that most of what drives us happens below conscious awareness — in the unconscious mind. He focused on early childhood, arguing that unresolved experiences from our first years become buried but continue to shape our adult lives, often showing up as anxiety, difficult patterns in relationships, or unexplained feelings.
Erik Erikson
A map for the whole of life
Erikson agreed that early experiences matter deeply, but went further — arguing that we never stop developing. Each stage of life brings its own challenge, and each one is a chance to grow. Crucially, he believed that with the right support — including therapy — we can revisit and begin to heal challenges from earlier stages, even much later in life.

What this means for your therapy
You don't need to fit neatly into any stage
These models are frameworks — not diagnoses. They offer a language for understanding patterns, not a verdict on what went wrong.
Many people find that something from a very early stage still feels unresolved. That's normal, and it's exactly the kind of thing therapy can gently explore.
Erikson's most hopeful insight is that it's never too late. The challenges of any earlier stage can be revisited — and with support, something can shift.
Your therapist won't label you or tell you which stage you're "at." These ideas are simply a map — and maps are most useful when you choose where to look.
