The stages are drawn where development actually changes gear: 6 to 7 when concrete reasoning arrives, 10 to 11 at puberty onset and peak frontal grey matter, 13 to 15 as formal reasoning consolidates, and 16 to 18 at the social and legal shift into adulthood.

The Discoverers

4-7

The Discoverers

Thinking
Pre-operational: one thing at a time, magic still allowed
Body
Steady growth, gross motor ahead of fine motor
Sleep
10 to 13 hours, an early body clock, a ritual that must not change
Emotion
Feelings arrive whole and unnamed, and need your voice to land
Self-control
Borrowed from you: they calm because you are calm
Risk-seeking
Low, physical, and mostly about height
Social
Parallel play turning into real play, one friend at a time
Self-image
Made of what they can do today

The Builders

8-10

The Builders

Thinking
Concrete-operational from 6 or 7: rules, logic, reversible ideas
Body
Slower growth, real coordination, stamina for games with rules
Sleep
9 to 12 hours, and the first negotiations about bedtime
Emotion
Feelings get hidden as often as shown
Self-control
Their own, in short stretches, and better after food and sleep
Risk-seeking
Social as much as physical: who is watching matters
Social
Best friends, in-groups, and the sting of being left out
Self-image
Built by comparison with everyone else in the room

The Seekers

11-14

The Seekers

Thinking
Formal reasoning starting: hypotheticals, and holes in your argument
Body
Puberty onset, fast growth, a body that changed overnight
Hormones
Rising and uneven, so mood follows the day rather than the cause
Sleep
Body clock delays about an hour, so early school hurts
Emotion
Intensity up, tolerance down, and privacy about all of it
Self-control
Improving, but slower than the appetite for risk
Risk-seeking
Climbing, and strongly shaped by who is in the room
Social
Friends outrank family, and status is tracked constantly
Self-image
Fragile, comparative, and checked against a feed

The Trailblazers

Thinking
Formal reasoning consolidating: they can out-argue you and know it
Body
Near adult size, appetite and sleep debt both large
Hormones
Settling, but still loud enough to colour a whole week
Sleep
Latest body clock of the whole range, on the earliest schedule
Emotion
Felt fully, shown selectively, and rarely to you first
Self-control
Rising steadily, and reliable when they are rested
Risk-seeking
Sensation seeking peaks at 14 to 15, ahead of impulse control
Social
Peer world is the real world; privacy is non-negotiable
Self-image
Tried on in versions, and defended hard while it is being tried
