Towards a brain-controlled hearing aid: PhD student Lorenz Fiedler shows how attended and ignored auditory streams are differently represented in the neural responses and how the focus of auditory attention can be extracted from EEG signals recorded at electrodes placed inside the ear-canal and around the ear.
Auditory Cognition’s own Malte Wöstmann is in press in Cerebral Cortex with his latest offering on how attentional control manifests in alpha power changes: Ignoring speech can be beneficial (if comprehending speech potentially detracts from another task), and we here show how this change in listening goals turns around the pattern of alpha-power changes with changing speech degradation. (We will update as the paper becomes available online.)

We are proud to publish our recent study on how network dynamics of beta-band oscillations in the human brain mediate response speed in auditory perceptual decision-making. This work will appear soon in the first volume of the promising journal Network Neuroscience.

Come and join us and an already superbe line-up of confirmed speakers in December in Lübeck.
PhD student Leonhard Waschke goes live (pre-peer-review) with his work on the states and traits of neural noise.
Here is the preprint of the paper, which now will undergo peer-review. Thanks for checking it out!
Story time: Some time in early 2011, I sat down with an American, fresh PhD graduate who had just joined my new lab, in a Leipzig bar (Café Cantona; if you are interested you can find this great 24⁄7 bar with exquisite food also in the acknowledgments of, e.g., Obleser & Eisner, Trends Cogn Sci, 2009).
To the day, I could still point you to the table she and I sat down at, and the wall I faced (which is notable because we actually spent an unhealthy amount of time and money there over the years). Soon thereafter, we grabbed a beer mat and started scribbling waves and marked where we would place so-called targets (psychologist lingo) and talked a lot of gibberish about frequency modulation. I remember vididly that I had just read an insanely long review paper on neural oscillations by Wolfgang Klimesch (that, more in passing, cited old-school tales of Schmitt filters by the late great Francesco Varela or pioneers sounding like record producers, Dustman & Beck, 1965), while the young American opposite me turned out to be an—if adventurous—die-hard expert on auditory psychophysics.
Who would have thought that this very night would carry me towards tenure in three years’ time, and her around the globe as an esteemed young colleague.
When I nowadays check Google scholar, I am amazed to see that already more than 100 other papers have cited what directly grew out of that beer mat one and a half years later—not counting the many more papers this said postdoc, Molly Henry, has produced since.
Wow: Massive congratulations to Lea Schmitt, who just has been awarded the Colin Cherry Award 2017 at the 9th Speech in Noise (SPIN) workshop in Oldenburg. Germany. The Colin Cherry award honours the best poster (audience award) and gets you a cocktail shaker set.
Lea’s work, which formed her MSc thesis, is both provocative and imaginative: Lea went after the ancient truism that closing your eyes helps you in difficult listening situations. Turns out it’s not that simple, but Lea established a very neat link to individual differences in alpha-power dynamics. Watch this space for a new paper to come (Schmitt, Obleser, & Wöstmann, forthcoming).
Lea is not only the first student to receive her MSc in the new Obleser lab in Lübeck, but (maybe not so) incidentally, she was mainly supervised by a former Colin Cherry Award winner himself, Obleserlab’s own Malte Wöstmann. Congratulations to both!
After great success in the past, we are proud to announce a new SNAP Workshop in 2017. It will take place at the University of Lübeck in December 2017 — save the date!
SNAP will gather 12–14 speakers and about 50 or so participants for comparably extensive talks and discussions in a two-day event, to be held amongst the pittoresque surroundings of UNESCO world heritage city Lübeck (near Hamburg). A poster session will be arranged. All details to follow.
