Along with Dr. Whitney Chappell, Dr. Matt Kanwit has published a new article in Studies in Second Language Acquisition now available online ahead of print through First View. They use a matched-guise task to determine whether second-language learners of Spanish associate aspiration (i.e., production of /s/ as [h]) with regional or social characteristics. The study contributes to what we know about the development of sociolinguistic competence in its consideration of learners' ability to perceive linguistic and social meaning conveyed through sociophonetic variation. The full article is available for free via Open Access and contains Open Data.
