We are very excited to share that Obleserlab postdoc Sarah Tune has a new paper in Nature Communications. „Neural attentional-filter mechanisms of listening success in middle-aged and older participants“ is our latest and to-date most extensive output of the longitudinal ERC Consolidator project on adaptive listening in ageing individual (AUDADAPT — include link to https://auditorycognition.com/erc-audadapt/).
This co-production with current (Mohsen Alavash and Jonas Obleser) and former (Lorenz Fiedler) Obleserlab members, takes an in-depth and integrative look at how two of the most extensively studied neurobiological attentional-filter implementations, alpha power lateralization and selective neural speech tracking, relate to one another and to listening sucess.
Leveraging our large, representative sample of aging listeners (N=155, 39–80 years), we show that both neural filter implementatins are robustly modulated by attention but operate surprinsingly independent of one another.
In a series of sophisticated single-trial linear models that include variation in neural filter strength within and between individuals, we demonstrate how the preferential neural tracking of attended versus ignored speech but not alpha lateralization boosts listening success.
