Repetition, but not acoustic differentiation, facilitates pseudohomophone learning by children
Children’s ability to learn words with multiple meanings may be hindered by their adherence to a one-to-one form-to-meaning mapping bias. Previous research on children’s learning of pseudohomophones has yielded mixed results, suggesting a range of factors that may impact when children entertain a new meaning for a familiar word. One such factor is repetition of the new meaning (Storkel & Maekawa, 2005) and another is the acoustic differentiation of the two meanings (Conwell, 2017). This study asked 72 4-year-old English-learning children to assign novel meanings to familiar words and manipulated how many times they heard the words with their new referents as well as whether the productions were acoustically longer than typical productions of the words. The results show that repetition supports the learning of a pseudohomophone, but acoustic differentiation does not. There was no evidence of an interaction of the two factors. Homophone learning is facilitated by increased exposure to a second meaning, but children do not use acoustic differences in homophone learning, despite the availability of such differences in their experience.
