Neuropsychological studies of knowledge systems have brought to light
some unexpected principles of organization.  Evidence for both modality
and category specificity will be presented.  It will be argued that
there are independent verbal and visual knowledge bases sub-served by
left temporal lobe structures.

Furthermore it will be argued that both these knowledge bases are
categorical in their organizzaztion.  Specifically a patient with loss
of knowledge of the category "living things" confined to the verbal 
domain and a patient with loss of knowledge of the category "inanimate
artefacts" confined to the visual domain will be described.

Patients in whom a modality by category interaction can be demonstrated
are of particular significance for theoretical models of knowledge
systems in the brain.

              This is the New York Neuropsychology Group's
              annual "supper" meeting; a joint meeting with 
              the Psychology Section and the Linguistic Section
              of The New York Academy of Sciences.

           The lecture begins at 6:00 pm, is free, and open to all.

           Reception and supper which follow at 7:30 pm are optional,
           and require reservations by Nov. 27 (Friday).
