Feature-based approaches to acquisition principally focus on second language (L2) learners' ability to perceive non-native consonants when the features required are either contrastively present or entirely absent from the first language (L1) grammar. As features may function contrastively or allophonically in the consonant and/or vowel systems of…

During spoken word processing, native (L1) listeners use allophonic variation to predictively rule out word competitors and speed up word recognition. There is some evidence that second language (L2) learners develop an awareness of allophonic distributions in their L2, but whether they use their knowledge to facilitate word recognition online,…

Spoken word recognition depends on variations in fine-grained phonetics as listeners decode speech. However, many models of second language (L2) speech perception focus on units such as isolated syllables, and not on words. In two eye-tracking experiments, we investigated how fine-grained phonetic details (i.e. duration of nasalization on…

Two accounts of the variable use of inflection in adult second language (L2) acquisition are examined: The Missing Surface Inflection Hypothesis (MSIH) and the Impaired Representation Hypothesis (IRH). These hypotheses make different predictions for adult L2 acquisition. Spontaneous production data from two adult learners of French and two adult…
