This paper investigates relationships between procedural-memory, declarative-memory, and working-memory skills and adult native English speakers’ novel sound-category learning. Participants completed a sound-categorization task that required integrating two dimensions: one native (vowel quality), one non-native (pitch). Similar information-integration category structures in the visual and auditory domains have been shown to be best learned implicitly (e.g., Maddox et al., 2006). Thus, we predicted that individuals with greater procedural-memory capacity would better learn sound categories, because procedural memory appears to support implicit learning of new information and integration of dimensions. Seventy undergraduates were tested across two experiments. Procedural memory was assessed using …

Studies of early-developing consonants (stops, nasals, and glides) in babbling have shown that most of the variance in consonants and their associated vowels, both within and between syllables, is due to a "frame" produced by mandibular oscillation, with very little active contribution from intrasyllabic or intersyllabic tongue movements. In a study of four babbling infants, the prediction that this apparently basic "frame dominance" would also apply to late-developing consonants (fricatives, affricates, and liquids) was tested. With minor exceptions, confirming evidence for both the predicted intrasyllabic and intersyllabic patterns was obtained. Results provide further evidence for the frame dominance conception, but …
