Course Description

 

 

 

Spatial cognition

Representational models of linguistic, psychological, and geographic space.

 

 

Christian Freksa

Universität Bremen

 

This course will cover models of spatial cognition that relate to linguistic descriptions of spatial configurations, to psychological insights of cognitive space, or to conceptions of geographic space. The first lecture will motivate research on spatial cognition and provide examples of using spatial structures in everyday situations; the second lecture will present results from psychological experiments on spatial cognition and memory; the third and fourth lecture will focus on artificial intelligence representations of spatial knowledge and on spatial reasoning; the fifth lecture will cover applications of spatial reasoning related to geographic space. The course is designed to be accessible to cognitive science graduate students with non-technical background (e.g. psychology, linguistics). A curiosity for informatics / computer science approaches to cognitive science will be helpful.

Small groups

 

Clarification of concepts and notions. Discussion of issues raised in the main classes and/or brought up by the participants. Participants will gain experience with various spatial representation models and discuss controversial topics. Discussions on topics that don't fit into the main lectures.

Assessment

 

Students who desire credit should write a 10 page paper on a topic selected by consultation with the lecturer, e.g. describing how concepts in Spatial Cognition relate to one another, how they are relevant to the student’s interests, or challenging approaches or opinions presented by the instructor.

 

 

 

 

Christian Freksa

 

Christian Freksa received his B.S. in computer science from the University of San Francisco and his M.S. and Ph.D. (artificial intelligence / cognitive science) from the University of California at Berkeley. He received a postdoctoral fellowship at the Max Planck Institute for Psychiatry in Munich in 1981 and held senior researcher and assistant professor positions at the Technical University in Munich from 1983 to 1991. In 1991 he joined the informatics faculty at the University of Hamburg.  From 1996 to 2002 he coordinated the Spatial Cognition Priority Program funded by the Deutsche Forschungs­gemein­schaft. In 2002 he moved to the University of Bremen where he is now professor of informatics and head of the Cognitive Systems research group. He coordinates the International Quality Network on Spatial Cognition and the Transregional Collaborative Research Center SFB/TR 8 Spatial Cognition: Reasoning, Action, Interaction at the Universities Bremen and Freiburg.
