Williams’s (2005) study on “learning without awareness” and three subsequent extensions (Faretta-Stutenberg & Morgan-Short, 2011; Hama & Leow, 2010; Rebuschat, Hamrick, Sachs, Riestenberg, & Ziegler, 2013) have reported conflicting results, perhaps in part due to differences in how awareness has been measured. The present extension of Williams (2005) addresses this possibility directly by triangulating data from three awareness measures: concurrent verbal reports (think-aloud protocols), retrospective verbal reports (postexposure interviews), and subjective measures (confidence ratings and source attributions). Participants were exposed to an artificial determiner system under incidental learning conditions. One experimental group thought aloud during training, another thought aloud during training and testing, and a third remained silent, as did a trained control group. All participants were then tested by means of a forced-choice task to establish whether learning took place. In addition, all participants provided confidence ratings and source attributions on test items and were interviewed following the test. Our results indicate that, although all experimental groups displayed learning effects, only the silent group was able to generalize the acquired knowledge to novel instances. Comparisons of concurrent and retrospective verbal report data shed light on the conflicting findings previously reported in the literature and highlight important methodological issues in implicit and explicit learning research.

Task-based language teaching (TBLT) is a pedagogical approach that involves identifying real-world tasks that learners need to be able to do in the target language and then developing classroom-appropriate, context-specific versions of these tasks. In this paper, we use Long’s methodological principles for TBLT to evaluate a task-based approach within two Indigenous language-teaching contexts: the Macuiltianguis Zapotec classroom in Oaxaca, Mexico, and a workshop for teachers of Salish Qlipse in the state of Montana. Throughout the article, we give special consideration to issues of investment in the target language, expanding on Norton’s definition of language learner investment to argue that teacher and community investment in the language and language revitalization process are critical to the successful implementation of TBLT in Indigenous contexts.
