Revisiting: Can horses recognize with one eye an object seen only with the other?

Horses will startle at an object they see with their left eye that they have only seen with the right. It used to be thought that horses could literally not transfer information from one eye to the other.

This is actually incorrect. Studies have proved this - the issue is actually more one of object persistence. The horse does not realize it is the same object when they view it from different directions.
