| summary | Early theories of spatial memory and navigation stipulate that animals, including humans, have an enduring cognitive map of objects in the environment and during locomotion update the representation of their location and orientation in the cognitive map (e.g., Gallistel, 1990; O’Keefe & Nadel, 1978; Tolman, 1948). However these theories have been challenged recently by the proposal that human spatial navigation primarily relies on egocentric representations that are dynamically updated during navigation (e.g., Wang & Spelke, 2003). In this talk, I will propose that people organize their spatial memory in terms of a fixed reference direction and update their position and orientation in terms of the same fixed reference direction during locomotion and navigation, consistent with the theories of enduring spatial memory. I will also review evidences we collected in the past 15 years to support this proposal. |
