The type of processing-resource allocation (TOPRA) model predicts that increasing one type of processing (semantic, structural, or mapping oriented) can decrease other types of processing and their learning counterparts. This study examined how semantic and structural tasks affect the mapping component of second language (L2) vocabulary learning.…

Because reading for meaning only can lead to low rates of second language (L2) vocabulary learning and because previous research has demonstrated the benefits of word retrieval opportunities for intentional L2 vocabulary learning (Barcroft, 2007; McNamara & Healy, 1995a, Experiment 2; Royer, 1973), the present study assessed the effect of…

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…

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)…
