{"pk":29050,"title":"Proposing a Cognitive System for Universal Mental Spatial Transformations","subtitle":null,"abstract":"Mental spatial transformation processes are often modeled by assuming imaginal processes, highly task-specific assump-tions, or both. We propose the existence of a dedicated, unified cognitive system for the simulation of spatial processes,and show ways to model this system, including an ACT-R implementation that is currently in development. Results ofspatial cognition and brain-imaging research support this proposal. Operations of this system are proposed to be influencedby their complexity, which we assume to be a product of the extent and amount of necessary transformation steps. Thiscomplexity is further assumed to be limited in its extent, possibly explaining decision time effects between task difficul-ties in a mental folding task as being caused by cognitive re-encoding processes. A model for the mental folding tasklacking such a spatial system is presented, serving as a baseline to demonstrate the need of a system dedicated to mentaltransformations.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Poster Presentations with Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9z54s521","frozenauthors":[{"first_name":"Kai","middle_name":"","last_name":"Preuss","name_suffix":"","institution":"Technical University Berlin","department":""},{"first_name":"Nele","middle_name":"","last_name":"Russwinkel","name_suffix":"","institution":"Technical University Berlin","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2019-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29050/galley/18921/download/"}]}
