Headphones where the left and right play different things. Have people pay attention one, other or both ears. When someone listens to just one side of the ear, they do well knowing what they heard.

Both ears too much to process bottleneck of processing. Attention happens before you even really know what something is. Choosing things that are important before you even identify what they are.
