Somatic brain · Procedural Memory & Motor Habit

Muscle Memory / Procedural

Procedural memory stores practised action sequences in the basal ganglia and cerebellum so they run without conscious control; a rehearsed yes, a reflex tap or a habitual signature executes before you decide.

An everyday example

Tapping 'Accept' on an updated terms dialog because your thumb has done it a hundred times, then realising it changed the price.

What it can cost you

Actions that fire before evaluation, and interfaces designed to ride your existing motor habits.

Warning signs

  • I tapped before I read.
  • My hand knew the flow better than I did.

One thing to do

Put a different motion between habit and consequence: move the button, use the other hand, or read one line aloud before any practised confirm.
