New paper in press — Scharinger et al., PLOS ONE [Update]
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 16th, 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.[Update]
