Using computational Social Network Analysis (SNA), this longitudinal study investigates the development of the interaction network and its influence on the second language (L2) gains of a complete cohort of 41 U.S. sojourners enrolled in a 3-month intensive study-abroad Arabic program in Jordan. Unlike extant research, our study focuses on…

The author's response to James Flege's critique (in this issue of "Language Learning") regarding earlier research on second-language timing patterns is presented. (LMO)

Presents the results of an experiment which examined the temporal characteristics of voiceless plosives in American English, Arabic, and Arabic-accented English. Results showed that Arabic-accented English departed from the target language goal and constituted an articulation type characterizable as more Arabic than Arabic itself. (Author/SED)

Discusses the design and interpretation of instrumental phonetic studies of second language (L2) speech production. The speech of L2 learners is evaluated to determine to what extent it diverges from the differing phonetic norms of L1, which are estimated from the speech of a small number of native speakers.

Studies learners' second-language (L2) oral proficiency, incorporating an interview, a narration, and a read-aloud. Results show that the nature of the L2 oral construct is not constant. The article concludes that proficiency researchers should use dimensions empirically derived according to the specific elicitation task and audience. (53…
