We’ll be hir­ing soon: Post­docs wanted

The research group “Audi­to­ry Cog­ni­tion” (head­ed by Prof. Dr. Jonas Obleser; auditorycognition.com) in the recent­ly estab­lished Depart­ment of Psy­chol­o­gy, Uni­ver­si­ty of Lübeck, is seek­ing to hire several

Post­doc­tor­al Researchers

start­ing by Jan­u­ary 2016, ini­tial­ly for 3 years, with the option of a 2‑year exten­sion. These posi­tions will fall into the larg­er frame­work of an ERC Con­sol­ida­tor grant “The lis­ten­ing chal­lenge: How age­ing brains adapt” recent­ly award­ed to Jonas Obleser, and will allow the joint devel­op­ment of cog­ni­tive neu­ro­science and psy­cho­log­i­cal research projects tar­get­ing adap­tive con­trol in the audi­to­ry modal­i­ty of mid­dle-aged adults.

[About the ERC project: The audi­to­ry sen­so­ry modal­i­ty pos­es an excel­lent, although under-utilised, research mod­el to under­stand the cog­ni­tive adjust­ments to sen­so­ry change (here termed “adap­tive con­trol”), their neur­al basis, and their large vari­a­tion amongst indi­vid­u­als. Hear­ing abil­i­ties begin to decline already in the fourth life decade, and our guid­ing hypoth­e­sis is that indi­vid­u­als dif­fer in the extent to which they are neu­ral­ly, cog­ni­tive­ly, and psy­cho­log­i­cal­ly equipped to adapt to this sen­so­ry decline.]

We are look­ing for cre­ative minds with a PhD degree and a promis­ing track record in cog­ni­tive neu­ro­science, psy­chol­o­gy, physics, or engi­neer­ing. A strong back­ground and inter­est in research meth­ods is desir­able. Pri­or expe­ri­ence with either human neu­ro­science meth­ods (espe­cial­ly advanced EEG and/or fMRI analy­ses) or mod­el­ing of rich data sets (e.g., latent growth mod­el­ing, struc­tur­al equa­tion mod­el­ing) is expected.

The Uni­ver­si­ty of Lübeck is a mod­ern uni­ver­si­ty spe­cial­iz­ing in Med­i­cine, Com­put­er Sci­ence, Mol­e­c­u­lar Biol­o­gy, Bio­math­e­mat­ics and Med­ical Engi­neer­ing. Inter­na­tion­al­ly renowned research and high stan­dards of aca­d­e­m­ic tutor­ing char­ac­ter­ize the pro­file of the uni­ver­si­ty. A new ded­i­cat­ed research build­ing (Cen­tre for Brain, Behav­iour, and Metab­o­lism; CBBM) hous­ing also the Obleser lab will open in late 2015.

Pay­ment will fol­low salary group E13 TV‑L (full time), if con­di­tions based on Ger­man Pub­lic ser­vice reg­u­la­tions are satisfied.

 

These posi­tions will be announced offi­cial­ly lat­er in autumn 2015, but inter­est­ed can­di­dates should be in touch now with Jonas Obleser, jonas.obleser@uni-luebeck.de

ERC Con­sol­ida­tor Grant award­ed to Jonas Obleser

It is with great plea­sure that we can report on a new major grant for the Audi­to­ry Cog­ni­tion group / Obleser lab: In the 2014 call by the Euro­pean Research Coun­cil (ERC), Jonas Obleser has very recent­ly been award­ed an ERC Con­sol­ida­tor grant (for researchers 7–12 years post their PhD), worth 1.97 mil­lion €. The grant has been award­ed to fund a project enti­tled “The lis­ten­ing chal­lenge: How age­ing brains adapt”. The project will last for five years.

New paper in press in the Jour­nal of Neu­ro­science: Wöst­mann, Her­rmann, Wilsch, & Obleser [UPDATED #2]

Con­grat­u­la­tions to AC PhD stu­dent Malte Wöst­mann for his new­ly accept­ed paper in the Jour­nal of Neu­ro­science!

Wöst­mann M, Her­rmann B, Wilsch A, & Obleser J.

Neur­al alpha dynam­ics in younger and old­er lis­ten­ers reflect acoustic chal­lenges and pre­dic­tive benefits

J Neu­rosci, in press.

Here is the abstract and my favourite fig­ure from Malte’s paper.

Abstract
Speech com­pre­hen­sion in mul­ti-talk­er sit­u­a­tions is a noto­ri­ous real-life chal­lenge, par­tic­u­lar­ly for old­er lis­ten­ers. Younger lis­ten­ers exploit stim­u­lus-inher­ent acoustic detail, but are they also active­ly pre­dict­ing upcom­ing infor­ma­tion? And fur­ther, how do old­er lis­ten­ers deal with acoustic and pre­dic­tive infor­ma­tion? To under­stand the neur­al dynam­ics of lis­ten­ing dif­fi­cul­ties and accord­ing lis­ten­ing strate­gies, we con­trast­ed neur­al respons­es in the alpha-band (~10 Hz) in younger (20−30 years, n = 18) and healthy old­er (60−70 years, n = 20) par­tic­i­pants under chang­ing task demands in a two-talk­er par­a­digm. Elec­troen­cephalo­grams were record­ed while humans lis­tened to two spo­ken dig­its against a dis­tract­ing talk­er and decid­ed whether the sec­ond dig­it was small­er or larg­er. Acoustic detail (tem­po­ral fine struc­ture) and pre­dic­tive­ness (the degree to which the first dig­it pre­dict­ed the sec­ond) var­ied orthog­o­nal­ly. Alpha pow­er at wide­spread scalp sites decreased with increas­ing acoustic detail (dur­ing tar­get dig­it pre­sen­ta­tion) but also with increas­ing pre­dic­tive­ness (in-between tar­get dig­its). For old­er com­pared to younger lis­ten­ers, acoustic detail had a stronger impact on task per­for­mance and alpha pow­er mod­u­la­tion. This sug­gests that alpha dynam­ics plays an impor­tant role in the changes in lis­ten­ing behav­ior that occur with age. Last­ly, alpha pow­er vari­a­tions result­ing from stim­u­lus manip­u­la­tions (of acoustic detail and pre­dic­tive­ness) as well as task-inde­pen­dent over­all alpha pow­er were relat­ed to sub­jec­tive lis­ten­ing effort. The present data show that alpha dynam­ics is a promis­ing neur­al mark­er of indi­vid­ual dif­fi­cul­ties as well as age-relat­ed changes in sen­sa­tion, per­cep­tion, and com­pre­hen­sion in com­plex com­mu­ni­ca­tion situations.
