Lis­ten­ing: The strat­e­gy mat­ters [Update]

In press on Neu­ropsy­cholo­gia

Thal­a­m­ic and pari­etal brain mor­phol­o­gy pre­dicts audi­to­ry cat­e­go­ry learn­ing

Cat­e­go­riz­ing sounds is vital for adap­tive human behav­ior. Accord­ing­ly, chang­ing lis­ten­ing sit­u­a­tions (exter­nal noise, but also periph­er­al hear­ing loss in aging) require lis­ten­ers to flex­i­bly adjust their cat­e­go­riza­tion strate­gies, e.g., switch amongst avail­able acoustic cues. How­ev­er, lis­ten­ers dif­fer con­sid­er­ably in these adap­tive capa­bil­i­ties. For this rea­son, we employed vox­el-based mor­phom­e­try (VBM) in our study (Neu­ropsy­cholo­gia, In press), in order to assess the degree to which indi­vid­ual brain mor­phol­o­gy is pre­dic­tive of such adap­tive lis­ten­ing behav­ior.

New paper has been pub­lished in Cere­bral Cor­tex by Hen­ry, Her­rmann, & Obleser

When we lis­ten to sounds like speech and music, we have to make sense of dif­fer­ent acoustic fea­tures that vary simul­ta­ne­ous­ly along mul­ti­ple time scales. This means that we, as lis­ten­ers, have to selec­tive­ly attend to, but at the same…

New paper out: Erb, Hen­ry, Eis­ner & Obleser — Jour­nal of Neu­ro­science

We are proud to announce that PhD stu­dent Julia Erb just came out with a paper issued in Jour­nal  of Neu­ro­science:

The Brain Dynam­ics of Rapid Per­cep­tu­al Adap­ta­tion to Adverse Lis­ten­ing Con­di­tions

Effects of adaptation

Abstract:

Lis­ten­ers show a remark­able abil­i­ty to quick­ly adjust to degrad­ed speech input. Here, we aimed to iden­ti­fy the neur­al mech­a­nisms of such short-term per­cep­tu­al adap­ta­tion. In a sparse-sam­pling, car­diac-gat­ed func­tion­al mag­net­ic res­o­nance imag­ing (fMRI) acqui­si­tion, human lis­ten­ers heard and repeat­ed back 4-band-vocod­ed sen­tences
