title: Infants' name recognition in on- and off-channel noise.
abstract: Previous work by Polka, Rvachew, and Molnar [Infancy 13(5), 421-439 (2008)] has reported that infants are poor at focusing their attention on a particular frequency range, and, as a result, are distracted by maskers that are outside of the target frequency range. The current study explores this effect of irrelevant distractors further and finds that 8-month-old infants are significantly less affected by maskers outside the frequency range (off-channel maskers) than by on-channel maskers. Thus while infants may display difficulty ignoring irrelevant distractors, they are able to do so to at least some degree, suggesting some ability to perceive speech from spectrally remote maskers, despite the demonstrated presence of greater informational masking at this age.
