Study Summary
The overarching goal of the proposed research is to understand how human listeners learn speech categories. The project takes a prospective approach with adult second-language learners, blending empirical, methodological and theoretical advances from laboratory studies with explicit classroom instruction. The central hypothesis is that incidentally-acquired nonlinguistic perceptual building block categories may support speech perception and production in a second language. The project will advance important theoretical debates about the cross-talk between general auditory representations and speech categories and will provide a novel approach to nudging adult learners off learning plateau typically encountered in classroom instruction.
Primary Outcome
Each participant's 96 auditory discrimination data points at Pre-test and Post-test, respectively, were reduced to one sensitivity score: d-prime (d': hits minus false alarms). This transformation takes into account response bias and approaches a normal distribution. A higher score represents greater sensitivity. The difference in scores from pre- to post-test represents the change.
