 ional Analysis: Constraints on the Approach to Optimality. In W.D. Gray (E

 ailable online at:\nhttp://www.informatics.manchester.ac.uk/~ahowes/articl
 es/Howes.2005.IMoCS.pdf\n\nOriginal abstract:\nWe critique rational analys
 is (Anderson\, 1990) with which Anderson emphasised the need for purposive
  explanations of the conditions influencing the adaptation of cognition to
  objective and environment only. We also critique the modeling and data fi
 tting methodology used with simulations of the human cognitive architectur
 e. In response\, we sketch the requirements for an\napproach to explaining
  behaviour that emphasises explanations in terms of the optimal behaviour 
 given not only descriptions of the objective function and environment but 
 also constraints on the human cognitive architecture and knowledge. A cent
 ral assumption of the proposal is that a theory explains behaviour if the 
 optimal behaviour predicted by the theory shows substantial\ncorrespondenc
 e to asymptotic human performance.\n\nRubric for the reading group: \nEver
 yone attending is expected to read the paper in advance. Please bring a co
 py with you\, preferably annotated with interesting reflections. The forma
 t of discussion will be a brief invited introduction/critique by two membe
 rs of the group\, followed by general discussion and informal mixing.
