Further characterization of "subject's own name (SON) negativity," an ERP component reflecting early preattentive detection of SON.

摘要: Subject’s own name (SON) is detected automatically and unconsciously in the brain. SON negativity, an early wave mismatch negativity latency range, has been proposed as a potential event-related (ERP) index of automatic preattentive detection SON. probably not general measure familiarity, it elicited by subject’s parent’s name. We further investigated specificity this response testing whether to which subjects were strongly but only temporarily familiarized. Subjects performed task detect arbitrary unfamiliar for forty minutes. Then, that was presented randomly equiprobably with nine novel names while they played video game tried ignore sounds. elicited, even when spontaneously noticed hearing familiarized The finding supports notion represents specific ERP SON, rather than familiarity.
