Physical attributes of an unattended channel are heard even though participants seem oblivious to the unattended channel"s semantic content.

You somehow block processing of the inputs you"re not interested in. You are also able to promote the processing of desired of stimuli. In an experiment, participants were instructed to point their eyes at the dot in the middle of the screen and make judgments about a cross shown off to the side. The dot itself briefly changed to another shape. If the participants were not warned about the change, they never noticed the change even though it was in front of them.
