This map is a macroscopic, historical, trans-disciplinary introduction to (the) cognitive science(s).
Moving from left to right, the map is read in a roughly historical fashion, but not literally, as we are compressing a n-dimensional intellectual space into a two dimensional map grid.
Unfortunately there is no way to generate an educational map that has everyone and everything on it. As such, there is always someone who should be on the map who is not.
The attempt of abstracting from reality always asks the question of (the most) relevance, in this case primarily to an beginner audience and especially students of the MEi:CogSci programme.
