Previous studies of word learning have presented the items to listeners under ideal
conditions. Here we ask how listeners learn new vocabulary items under adverse listening
conditions. Would listeners form acoustically-specific representations that incorporated
the noise, base their representations on noise-free language knowledge, or both? To
address these questions, listeners learned 16 words as labels for unfamiliar shapes
presented on a computer display. During the learning phase, word-shape pairings were
presented with either clear or white-noise-embedded tokens. For each word (e.g. dabo),
another word shared consonants (e.g. dubei) and a third shared vowels (e.g. gapo).
Learning was assessed in a 4AFC picture-selection task. The highest accuracy and speed
