the brain focuses a person’s attention on a particular stimulus, usually auditory. This focus excludes a range of other stimuli from conscious awareness, as when a partygoer follows a single conversation in a noisy room. it has been proposed that a person’s sensory memory subconsciously parses all stimuli and identifies discrete portions of these sensations
