An Incremental Cognitive Architecture of Consciousness with Global Workspace Theory

This paper revisits the GlobalWorkspace Theory as a neuroscientifically plausible theory for developing conscious cognitive architecture. Based on the discussion of the authors’ previous implementations, the Global Workspace Theory’s compatibility with the working mechanisms underneath human brains is enhanced by demonstrating cognitive features of attention and consciousness. To progress in the incremental research pathway for the architecture implementation, two principles of work are stressed. The primitive cognitive mechanisms are emphasised more than the functional complexity and the revision-update cycle for implementation is appreciated for its engineering feasibility. Along the incremental pathway, the idea for possible following attempts is shared. Based on the discussion of completed and following implementations, the authors’ works are consistent with the Biologically Inspired Cognitive Architecture roadmap.
