dc.description.abstract | In multitalker backgrounds, the auditory cortex of adult humans tracks the attended speech stream rather than the global auditory scene.
Still, it is unknown whether such preferential tracking also occurs in children whose speech-in-noise (SiN) abilities are typically lower
compared with adults. We used magnetoencephalography (MEG) to investigate the frequency-specific cortical tracking of different
elements of a cocktail party auditory scene in 20 children (age range, 6–9 years; 8 females) and 20 adults (age range, 21– 40 years; 10
females). DuringMEGrecordings, subjects attended to four different 5 min stories, mixed with different levels of multitalker background
at four signal-to-noise ratios (SNRs; noiseless, 5, 0, and 5 dB). Coherence analysis quantified the coupling between the time courses
of the MEG activity and attended speech stream, multitalker background, or global auditory scene, respectively. In adults, statistically
significant coherence was observed between MEG signals originating from the auditory system and the attended stream at 1, 1– 4, and
4–8 Hz in all SNR conditions. Children displayed similar coupling at 1 and 1– 4 Hz, but increasing noise impaired the coupling more
strongly than in adults. Also, children displayed drastically lower coherence at 4–8 Hz in all SNR conditions. These results suggest that
children’s difficulties to understand speech in noisy conditions are related to an immature selective cortical tracking of the attended
speech streams. Our results also provide unprecedented evidence for an acquired cortical tracking of speech at syllable rate and argue for
a progressive development of SiN abilities in humans. | es_ES |
