ABSTRACT
Earlier chapters demonstrated how ACT–R can do a good job of accounting for the microlevel of cognition. This emphasis on the lower level, however, raises the question of whether ACT–R can scale to very complex cognitive tasks—can ACT–R models of very complex tasks be developed at this microlevel of detail both in a reasonable amount of time and without being overwhelmed by microdetail? Moreover, does this microlevel bring any advantages or new insights to the modeling of very complex tasks?
