Outline of Final Research Achievements

We have investigated how L2 learners build new phonological categories by assembling novel weightings of acoustic cues and mapping them onto new segmental representations. The series of experimental studies we have conducted has shown that the use of particular acoustic cues changes over the course of L2 acquisition. We have also shown that resulting refinements in selective attention improve L2 perceptual accuracy, although the precise effect of such selective attention differs across phonological categories.
