Re: Working memory (Reading Span) & Speech in noise
Dear Christian,
we recently tested a group of young normal-hearing participants in a "cocktail party listening" task with two spatially separated interfering speakers (http://dx.doi.org/10.13140/RG.2.1.1876.9448 or http://www.staff.uni-mainz.de/oberfeld/downloads/oberfeld_kloeckner_DAGA2015_549.pdf ). The speech identification performance was significantly correlated with an intensity discrimination task under backward masking, indexing auditory selective attention (e.g. http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0099745 ). Binaural TFS sensitivity also explained a significant portion of the variance. However, there was no sign. relation with the reading-span score.
The data collection for a group of listeners aged 30-60 years will be completed end of April, will keep you updated...

> In a recent study (Fullgrabe, Moore, and Stone, 2015), we found a significant

> Reading-Span scores in an audiometrically normal-hearing group composed of
> young and older listeners. However, this correlation was no longer significant
