 Moray's 1959 study found a 33% detection rate for personal names, which revealed that participants sometimes notice their name in an ignored auditory channel.This ability to selectively attend to one's own name has been found in infants as young as five months of age and appears to be fully developed by thirteen months of age.Rochelle S. Newman in a 2005 study found that five-month-old infants listened longer to their names when the target voice was 10 dB, but not 5 dB more intense than the background noise.
