{"pk":32624,"title":"Memory for Goals: An Architectural Perspective","subtitle":null,"abstract":"The notion that memory for goals is organized as a stack is central in cognitive theory in that stacks are core constructs leading cognitive architectures. However, the stack over-predicts the strength of goal memory and the precision of goal selection order, while under- predicting the maintenance cost of both. A better way to study memory for goals is to treat them like any other kind of memory element. This approach makes accurate and well-constrained predictions and reveals the nature of goal encoding and retrieval processes. The  approach is demonstrated in an ACT-R model of human performance on a canonical goal-based task, the Tower of Hanoi. The model and other considerations suggest that cognitive architectures should enforce a two-element limit on the depth of the stack to deter its use for storing task goals while preserving its use for attention and learning.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Long Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9tg8z072","frozenauthors":[{"first_name":"Erik","middle_name":"M.","last_name":"Altmann","name_suffix":"","institution":"Human Factors & Applied Cognition, George Mason University","department":""},{"first_name":"J.","middle_name":"Gregory","last_name":"Trafton","name_suffix":"","institution":"Naval Research Laboratory, Code 5513","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1999-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/32624/galley/23688/download/"}]}
