Participants wore headphones and heard one input in the left ear and another input in the right ear and instructed to pay attention to one of these inputs (attended channel) and ignore the other (unattended channel) Shadowing: ensured participants were paying attention; participants must repeat speech from the attended channel word for word. Shadowing was nearly perfect but heard remarkably little from the unattended channel. Similar phenomenon is seen with visual inputs.
