New paper published in The Journal of Neuroscience

"Neural Signatures of the Processing of Temporal Patterns in Sound" by Bjorn Herrmann and Ingrid Johnsrude has been published in the Journal of Neuroscience. Check it out here:

About the paper: Optimal perception requires that the auditory system detects regularities in sounds. Synchronized neural activity and increases in sustained neural activity both appear to index the detection of a regularity, but the functional interrelation of these two neural signatures is unknown. In three electroencephalography experiments, we measured both signatures concomitantly while listeners were presented with sounds containing frequency modulations that differed in their regularity. We observed that both neural signatures are sensitive to temporal regularity in sounds, although they functionally decouple when a listener is distracted by a demanding visual task. Our data suggest that neural synchronization reflects a more automatic response to regularity compared with sustained activity, which may be influenced by attentional, contextual, or other experiential factors.

Congratulations, Bjorn and Ingrid!

New paper accepted in Psychological Science

A paper by Emma Holmes, Ysabel Domingo, and Ingrid Johnsrude titled, "Familiar voices are more intelligible, even if they are not recognized as familiar" has been accepted in Psychological Science.

This papers demonstrates a dissociation between explicit recognition of a familiar voice and the speech-intelligibility benefit gained from a familiar voice in the presence of a competing talker. The findings imply that different mechanisms may be involved in processing familiar-voice information, depending on the context in which the information is used.

Honours thesis students Luka Petrusevski, Vivian Huynh, and Young Choi presented their projects at Honours Thesis Poster Session in the Social Sciences Building on March 23, 2018. 

Luka's presented his project titled, 'The Influence of an Irrelevent Sound Dimension on Sound Perception: Does Sound Complexity Matter?'. Vivian's project was 'The Role of Familiar Voice Pitch Cues on Speech Intelligibility in Multi-Talker Backgrounds', and Young's poster was called 'Evaluating the Effects of Temporal Lobe Epilepsy on Temporal Memory'. 

Congratulations on your hard work!

Ingrid Johnsrude, Bjorn Herrmann, Ysabel Domingo, and former post-docs Emma Holmes, Alex Billig, and Julia Huyck attended the 41st Annual Midwinter Meeting of the Association of Research in Otolaryngology in San Diego, California. 

Alex and Emma co-moderated a symposium called Non-Acoustic Influences on Speech Perception in Normal and Impaired Hearing. Alex gave a talk on "Linguistic Knowledge Affects Auditory Streaming of Speech: Insights from Intracranial Recordings and Functional Magnetic Resonance Imaging", and Emma's talk was titled, "Talker familiarity improves speech understanding in the presence of simultaneous talkers". 

Bjorn, Alex, and Ysabel presented posters. Bjorn and Alex were part of the Auditory Cortex, Speech, and Music poster session. Bjorn's poster was about "Sound pattern processing: Neural synchronization and sustained neural activity", and Alex's poster was "Alpha Oscillations Within Human Auditory Cortex: An Intracranial Electrophysiology Study". Ysabel's poster was part of the Attention, Audiovisual Integration & Sound Localization session and was called "Using spatial release from masking to estimate the magnitude of the familiar-voice intelligibility benefit".

New publication in The Journal of Neuroscience

A new paper by Bjorn Herrmann and Ingrid Johnsrude was accepted for publication by The Journal of Neuroscience. In this paper, we investigate whether human auditory cortex responses adapt to stimulus statistical distributions and how aging affects adaptation to stimulus statistics. Both age groups demonstrated adaptation to sound-level stimulus statistics, but adaptation was incomplete in older people. The lack of full adaptation to the statistics of the sensory environment may be a physiological mechanism underlying the known difficulty older adults have with filtering out irrelevant sensory information.
