Butterworth (1999) The Mathematical Brain London, Macmillan and Stanislas
Dehaene (1997) The Number Sense London Penguin Books make quite a case for

Subject: the role of externalization

> Amelia takes out a pencil, turns its eraser side toward the desk,
> pantomimes the written calculation, and says, "48."
> So, consistent with work of Goldin-Meadow, one role of gesture is to

> fully internalized and accessible by seeing "in the mind's eye."
