The Chrastil Lab was awarded a grant from NSF for “Cognitive graphs: The geometry of spatial knowledge”. The grant will use VR to study how people understand navigational space and the underlying geometry of cognitive maps.

The Chrastil Lab has published a paper in Cognition: “Vision and proprioception make equal contributions to path integration in a novel homing task.” The paper examines the loop closure task, contrasting levels of vision and proprioceptive information, finding them to make equal contributions. However, the two cues were not weighted in a Bayesian ideal manner.

Liz Chrastil gave a talk at the Society for Neuroscience Conference in November. This talk was principally concerned with the comparison of Theta oscillations during active and passive decision making in human spatial navigation. Theta oscillations have been related to learning in a number of contexts. Examining the role of these oscillations could give evidence into the role of passive and active decision making in navigational learning.
