Barcroft, Joe; Sommers, Mitchell S. – Studies in Second Language Acquisition, 2014
Previous studies (Barcroft & Sommers, 2005; Sommers & Barcroft, 2007) have demonstrated that variability in talker, speaking style, and speaking rate positively affect second language vocabulary learning, whereas variability in overall amplitude and fundamental frequency (F0) do not, at least for native English speakers. Sommers and…

Barcroft, Joe – Language Learning & Language Teaching, 2015
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…

Sommers, Mitchell S.; Barcroft, Joe – Applied Psycholinguistics, 2011
Research has demonstrated that second language (L2) vocabulary learning improves when target words are presented in acoustically varied compared with acoustically consistent formats. The present study investigated the extent to which this benefit of acoustic variability is a consequence of difficult encoding demands (cognitive effort hypothesis)…

Barcroft, Joe; Rott, Susanne – Applied Linguistics, 2010
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…

Barcroft, Joe – Applied Language Learning, 2003
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,…

Barcroft, Joe; Sommers, Mitchell S. – Studies in Second Language Acquisition, 2005
This study examined the effects of acoustic variability on second language vocabulary learning. English native speakers learned new words in Spanish. Exposure frequency to the words was constant. Dependent measures were accuracy and latency of picture-to-Spanish and Spanish-to-English recall. Experiment 1 compared presentation formats of neutral…
