The Leabra architecture: Specialization without modularity

  • Alexander A. Petrov (a1), David J. Jilk (a2) and Randall C. O'Reilly (a3)


The posterior cortex, hippocampus, and prefrontal cortex in the Leabra architecture are specialized in terms of various neural parameters, and thus are predilections for learning and processing, but domain-general in terms of cognitive functions such as face recognition. Also, these areas are not encapsulated and violate Fodorian criteria for modularity. Anderson's terminology obscures these important points, but we applaud his overall message.
