Egocentric search for disappearing objects in domestic dogs: evidence for a geometric hypothesis of direction.

摘要: In several species, the ability to locate a disappearing object is an adaptive component of predatory and social behaviour. domestic dogs, spatial memory for hidden objects primarily based on egocentric frame reference. We investigated geometric components information used by dogs they saw move disappear. experiment 1, distance direction between position animal hiding location were put in conflict. Results showed that directional their own coordinates target position. 2, accuracy finding using was estimated manipulating angular deviation adjacent locations animal. Four deviations tested: 5, 7.5, 10 15°. performance decreased as function but it clearly remained well above chance, revealing representation precise. discussion, we examine how why determine which
