The Literate Brain: Cognitive and Neural Bases

 

As an evolutionarily recent human invention, written language is

unlikely to be neurally instantiated on the basis of a literacy-specific

genetic blueprint.  Precisely for this reason, the study of the

cognitive and neural bases of written language provides an opportunity

to examine the human brain‘s  remarkable flexibility in acquiring

expertise and skill in novel domains.   I will present cognitive

neuropsychological and fMRI findings that shed light on the cognitive

and neural relationships between written and spoken language as well as

between written language and object/face processing.  The results reveal

an orthographic system that can operate with considerable autonomy from

the spoken language system; furthermore, this system makes use of

representational structures that are specifically orthographic  and is

instantiated , to at least some extent, in modality and

category-specific neural substrates.
