Abstract

Chicks were trained binocularly to find food buried under sawdust in the center of a square enclosure. When tested in an enclosure made larger or smaller in size binocular and left-eyed chicks searched mainly on the basis ofrelative distance of the food from the enclosure walls. Whereas right-eyedchicks searched on the basis of absolute distance. Moreover. binocular andleft-eyed chicks relied mainly oil global spatial information (i.e.. distances front the walls), whereas right-eyed chicks also used information provided by Visual landmarks. These results suggest that the right hemisphere of the avian brain fed most by the left eyed is primarily concerned with encoding of relational spatial information. Whereas, the left hemisphere (fed mainly by the right eye) is concerned with absolute metric information. possibly as part of an encoding strategy based primarily on local (both spatial and nonspatial) cues.
