Document Summary
A different message - the unattended channel - is presented in the left earphone. Participants easily follow one message and their shadowing performance is near per- fect and they hear little from the unattended channel. More recent studies have documented a similar pattern with visual inputs. E. g. video of people passing a ball and gorilla walks through and no one notices. People are not altogether oblivious to the unattended channel, physical attributes are heard but the semantic content is not. When the unattended channel said a series of names, including the participants"s own name, 1/3 of them heard their own voice the name seemed to catch their attention. Other things will also catch your attention if you are primed for them: mention of a movie you just saw, your favourite restaurant - words with personal importance this is referred to as the cocktail party effect. We have 2 options of how to think about attention.
