Left gaze bias in humans, rhesus monkeys and domestic dogs.

abstract：:In previous conditioning experiments training domestic chickens to magnetic directions, a brown strain solved the task, whereas a white strain seemed unable to do so (Freire et al. Anim Cogn 11:547-552, 2008). To test whether this was possibly caused by loss of magnetic compass orientation in the white chickens, we an...
