The virtuous circle: Modeling individual differences in L2 reading and vocabulary development

The present study investigated the relative contributions of experiential and ability factors to second language (L2) passage comprehension and L2 vocabulary retention. Participants included a cross section of 99 adult learners of Spanish as a foreign language enrolled in beginning through advanced level university Spanish courses. Participants completed a standardized reading proficiency test (Adult Basic Learning Examination, Spanish version) to verify a range in proficiency, a checklist and translation passage sight vocabulary test, and a written recall in the native language of the 4 passages that were read. Vocabulary retention was measured at 2 time intervals by a multiple-choice test of receptive retention of meaning of targeted vocabulary. Data were analyzed using structural equation modeling (SEM). Results revealed consistent support for the following model: (a) Language processing experience positively influenced L2 passage sight vocabulary; (b) L2 passage sight vocabulary positively influenced narrative passage comprehension; and (c) L2 comprehension positively influenced L2 vocabulary growth.
