The current study examined the effects of working memory training on working memory capacity and second language ability in adult learners of Spanish. In order to maximize the effect of the training for language learners, the stimuli for the training tasks were Spanish words and sentences. While the training group did not show greater improvements on working memory assessments relative to controls, they did show more native-like patterns in a Spanish self-paced reading task. The combination of second language materials with working memory training may be helping users learn to cope with the increased processing demands associated with learning a new language, even if they are not necessarily improving their working memory.
