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 the effects of semantic and structural elaboration on second language lexical acquisition. English-speaking low-intermediate Spanish learners attempted to learn 24 new Spanish words in three conditions. Results provide evidence that increased semantic processing can inhibit the ability to encode the formal properties of new words.…

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…
