Second language (L2) learners comprehend more when they are prepared for novel vocabulary that they encounter in a text. Input-based incremental (IBI) vocabulary instruction (Barcroft, 2012) provides L2 instructors and learners with a means of achieving this goal by (a) presenting optimal input to learners at the right time during a…

This book focuses on theory, research, and practice related to "lexical input processing" (lex-IP), an exciting field exploring how learners allocate their limited processing resources when exposed to words and lexical phrases in the input. Unit 1 specifies parameters of lex-IP research among other levels of input processing as well as…

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.…

This study examined how writing (copying) target words and word fragments affects intentional second language (L2) vocabulary learning. English-speaking first-semester learners of Spanish attempted to learn 24 Spanish nouns via word-picture repetition in three conditions: (1) word writing, (2) fragment writing, and (3) no writing. After the…
