The Auditory Perception and Cognition (APC) Lab was well represented at the recent Association for Research in Otolaryngology MidWinter Meeting held in San Jose, CA from January 25 to 29, 2020. The ARO is the world's largest organization representing hearing and balance researchers.

Lab members in attendance were: Andrew Oxenham, PhD, professor in the Department of Psychology at the University of Minnesota and director of the APC Lab, Magda Wojtczak, PhD, Anahita Mehta, PhD, Sara Madsen, PhD, Emily Allen, PhD, Jordan Beim, PhD, Juraj Mesik, PhD, Chhayakant Patro, PhD, Kelly Whiteford, PhD, Coral Dirks, Daniel Guest, and Hao Lu.

Undergraduate students Angela Sim and Kara Stevens also attended the conference and co-presented a poster with Dr. Kelly Whiteford. Their attendance was supported by an NSF supplement to encourage undergraduate participation in research.

Presentation and poster abstracts are available in the Conference Abstract Book.

These APC Lab members gave talks:

• Coral Dirks – “Using Temporal Envelope ITD Sensitivity to Match Electric and Acoustic Hearing in Patients with Unilateral Cochlear Implants and Residual, Contralateral Acoustic Hearing: Localization and Speech Perception Outcomes”
• Emily Allen – “Dissociating Spectral Envelope and Fundamental Frequency in Tonotopic Representations within Human Auditory Cortex”
• Juraj Mesik – “Effects of Age on the Electrophysiological Correlates of Continuous-speech Processing”
• Jordan Beim – “Examining the Efficacy of Forward-Pressure Calibrated Activators on Wideband Measures of the Middle-Ear Muscle Reflex”

These posters were presented by the group:

• Jordan Beim – “Rapid Simultaneous-Masked Spatial Tuning Curves in Cochlear-Implant Users”
• Andrew Oxenham (for Erin O’Neill) – “The Role of Semantic Context and Talker Variability in Speech Perception for Cochlear Implant Users and Normal-Hearing Listeners under Vocoded Conditions”
• Sara Madsen – “Benefit of Tonal Context on Relative Pitch Perception n Musicians and Non-musicians”
• Daniel Guest – “Modeling Pitch Perception of Concurrent High Frequency Complex Tones with Auditory Nerve Simulations”
• Hao Lu – “Isolating Neural Correlates of Streaming and Attention to Components within Complex Tones”
• Anahita Mehta – “Neural Correlates of Auditory Enhancement”
• Kelly Whiteford, Kara Stevens, and Angela Sim – “Musician Advantage for F0 Coding”
• Chhayakant Patro – “Effects of Tinnitus and Hearing Loss on Spatial Release from Speech-on-speech Masking and Physiological Proxies of Cochlear Synaptopathy”
• Collaboration with Prof. Hubert Lim, Biomedical Engineering – “Development and Translation of an Intracranial Auditory Nerve Implant” (no pdf available)
