Spontaneous object recognition memory is maintained following transformation of global geometric properties.

Poulter, S. L. and Kosaki, Y. and Easton, A. and McGregor, A. (2013) 'Spontaneous object recognition memory is maintained following transformation of global geometric properties.', Journal of experimental psychology : animal behaviour processes., 39 (1). pp. 93-98.

Abstract

Studies of spontaneous behavior to assess memory are widespread, but often the relationships of objects to contexts and spatial locations are poorly defined. We examined whether object-location memory was maintained following global, but not local, changes to the geometric shape of an arena. Rats explored two trial-unique objects in a distinctively shaped arena before being exposed to two identical copies of one of these objects in a different shape in a different physical location. Rats preferentially explored objects that were novel in relation to their local geometric context rather than identifying both locations as novel in the global geometric context.
