Abstract

Abstract : Although the ability to understand speech in adverse listening conditions is paramount for effective communication across the life span, little is understood about how this critical processing skill develops. This study asks how the dynamics of spoken word recognition (i.e., lexical access and competition) change during soft speech in 8‐ to 11‐year‐olds ( n = 26). Lexical competition and access for speech at lower intensity levels was measured using eye‐tracking and the visual world paradigm. Overall the results suggest that soft speech influences the magnitude and timing of lexical access and competition. These results suggest that lexical competition is a cognitive process that can be adapted in the school‐age years to help cope with increased uncertainty due to alterations in the speech signal.
