<unk>  is a psychological test commonly used to investigate selective attention and the lateralization of brain function within the auditory system. It is used within the fields of cognitive psychology and neuroscience. In a standard<unk>  test, a participant is presented with two different auditory stimuli simultaneously (usually speech), directed into different ears over headphones. In one type of test, participants are asked to pay attention to one or both of the stimuli; later, they are asked about the content of either the stimulus they were instructed to attend to or the stimulus they were instructed to ignore.
