We are hap­py that our paper

A Sparse Neur­al Code for Some Speech Sounds but Not for Others

is sched­uled for pub­li­ca­tion in PLOS ONE on July 16^th, 2012.

This is also our first paper in col­lab­o­ra­tion with Alexan­dra Ben­dix­en from the Uni­ver­si­ty of Leipzig.

The research report­ed in this arti­cle pro­vides an exten­sion of the pre­dic­tive cod­ing frame­work onto speech sounds and assumes that audi­to­ry pro­cess­ing uses pre­dic­tions that are not only derived from ongo­ing con­tex­tu­al updates, but also from long-term mem­o­ry rep­re­sen­ta­tions — neur­al codes — of speech sounds. Using the Ger­man min­i­mal pair [lats]/[laks] (bib/salmon) in a pas­sive-odd­ball design, we find the expect­ed Mis­match Neg­a­tiv­i­ty (MMN) asym­me­try that is com­pat­i­ble with a pre­dic­tive cod­ing frame­work, but also with lin­guis­tic under­spec­i­fi­ca­tion theory.
