Underlying dimensions of real-time word recognition in cochlear implant users

B. Mcmurray, F. X. Smith, et al.

This research uncovers three dimensions of real-time lexical competition in cochlear implant users and individuals without hearing loss, revealing how different auditory skills influence word recognition mechanisms. Conducted by Bob McMurray, Francis X. Smith, Marissa Huffman, Kristin Rooff, John B. Muegge, Charlotte Jeppsen, Ethan Kutlu, and Sarah Colby, these findings highlight the relationship between auditory processing and speech perception outcomes.

Abstract

This study identifies three underlying dimensions of real-time lexical competition in cochlear implant (CI) users and individuals without hearing loss, using the Visual World Paradigm. These dimensions – Wait-and-See, Sustained-Activation, and Slow-Activation-Rate – are predicted by different auditory skills and demographic factors. Higher Wait-and-See and Sustained-Activation scores correlate with poorer speech perception outcomes. These findings suggest that word recognition mechanisms vary systematically across individuals and listening contexts.
