Individual And Group Differences In Sound Category Learning, Ben Carlstrom

Student Research Symposium

Abstract: We examined the role of procedural-, declarative-, and working-memory systems in adults learning novel sound categories. Adults have fully developed declarative-memory skills that sometimes inhibit their ability to learn implicitly/procedurally (Filoteo, Lauritzen, & Maddox, 2010). Models of impaired language like the Procedural Deficit Hypothesis suggest that procedural-memory deficits are predictive of language-learning outcomes (Lum, Conti-Ramsden, Page, & Ullman, 2011). This study tested the hypothesis that language structure is best learned implicitly/procedurally, which has implications for L2 learning and language impairment. The novel sound categories presented to participants varied along a phonologically non-native dimension, pitch, and a native dimension, vowel …
