Kinesthetic Intelligence Before Language
The cognitive architecture the infant builds through movement alone — before language arrives — which persists as the substrate beneath every abstract thought.
Before the first word, there was movement. Sheets-Johnstone's framework establishes that by the time an infant produces her first word — typically around twelve months — she has already accomplished cognitive feats of staggering complexity entirely through her body's engagement with the world. She has learned object permanence, causal reasoning, spatial awareness, the properties of materials, the relationship between effort and weight. She has learned all of this without instruction, without language, without representation in any form a computational model would recognize. She has learned it through kinesthetic intelligence. And when language arrives, it does not replace this foundation — it builds on top of it.

The developmental evidence is extensive and converging. Infants as young as three months show 'violated expectation' responses — they look longer at physically impossible events (an object appearing to pass through a solid barrier) than at ordinary ones. This is not visual intelligence alone; the infant's expectation of solidity is built on
