Abstract:


This talk will provide an introduction to the CHREST architecture of cognition 
and show how this architecture can account for numerous data on the acquisition
of expertise and language.  The first part of the talk will explain the main 
components of the architecture and its learning mechanisms, which are based on
the concept of chunking. Then, experiments from chess expertise, covering 
perception, learning, and memory, will be described in some detail, and 
computer simulations with CHREST will be presented. Finally, simulations will 
show how the architecture can explain a number of data from the acquisition of
language, with a focus on syntax.  The talk will highlight the characteristics 
of CHREST that enable it to account for empirical data; these include self-
organisation, emphasis on cognitive limitations, presence of a perception-
learning-perception cycle, and use of naturalistic data as input for learning.
