Second language (L2) speakers often experience difficulties in learning words with L2-specific phonemes due to the unfaithful lexical encoding predicted by the fuzzy lexical representations hypothesis. Currently, there is limited understanding of how allophonic variation in the first language (L1) influences L2 phonological and lexical encoding.…

This study investigated classroom interaction through the framework of "stancetaking" (Du Bois, 2007) to understand how Spanish second language (L2) learners positioned themselves when participating in communicative language learning activities. Data came from transcribed audio and video recordings of three 90-minute lessons in one…

The range, variety, or diversity of words found in learners' language use is believed to reflect the complexity of their vocabulary knowledge as well as the level of their language proficiency. Many indices of lexical diversity have been proposed, most of which involve statistical relationships between types and tokens, and which ultimately…

Previous research has demonstrated substantially improved second language (L2) vocabulary learning when spoken word forms are varied using multiple talkers, speaking styles, or speaking rates. In contrast, the present study varied visual representations of referents for target vocabulary. English speakers learned Spanish words in formats of no…

Examined how acoustic variation affects second language (L2) lexical acquisition in consideration of four hypotheses: degraded input, elaborate processing, independent modulation, and robust versus strong connectivity. Beginners of L2 Spanish attempted to learn 24 Spanish words presented in 1 of 3 degrees of acoustic variation. Immediate and…
