Early Selection Model
Selective attention acts as a filter and unattended information only gets through if physically distinct (louder).
Late Filter Theory
Selective attention acts as a filter that blocks most unattended information from further processing but personally relevant and meaningful information can also be processed.

Mary is talking on her cellphone while at the store and is devoting her full attention to her conversation. While she is walking down the aisle, a young women next to her trips and falls.
