forthcoming. We will update you accordingly as the paper comes online. We will share however one of Malte’s figures here as a teaser: The paper utilises a very classic component of the evoked potential, the contingent negative variation (the CNV; or a close relative thereof, see the actual paper for discussion) to study how older and younger listeners allocate their attentional resources depending on implicit cues on to-be-expected listening difficulties.

The flexible allocation of attention enables us to perceive and behave successfully despite irrelevant distractors. How do acoustic challenges influence this allocation of attention, and to what exten […]
We are glad to announce that our paper (Mathias Scharinger, Samantha Poe, & William Idsardi) on cortical representations of Turkish vowels is in press in Journal of Cognitive Neuroscience. In this paper, we extend previous methods of obtaining centers of cortical activity evoked by vowel exemplars (e.g. Obleser et al., 2003, on German) and provide an N1m ECD (Equivalent Current Dipole) map of the entire vowel space of Turkish. Intriguingly, ECD locations mapped nearly perfect to locations in F2/F1 space, although our model comparison suggested that inclusion of discrete feature based predictors for both locations as well as collocations of vowels in auditory cortex improves the model fits substantially. We discuss the findings on the background of neural coding schemes for speech-related auditory categories.

Mammalian cortex is known to contain various kinds of spatial encoding schemes for sensory information including retinotopic, somatosensory, and tonotopic maps. Tonotopic maps are especially interesti […]
