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 on second language (L2) vocabulary learning has examined the relationship between word properties and learnability (e.g. Ellis and Beaton 1993). Few studies, however, have examined patterns in partial word form learning as a method of assessing learnability and improving our understanding of allocation of processing resources…

This study examined input enhancement and second language (L2) vocabulary learning while exploring the role of "distinctiveness," the degree to which an item in the input diverges from the form in which other items in the input are presented, with regard to the nature and direction of the effects of enhancement. In this study,…
