The role of awareness in implicit and explicit knowledge

Abstract

This study investigates the initial incidental acquisition of two L2 morphosyntactic rules and their immediate usage in production. Using a miniature artificial language paradigm, multiple exposure sessions, realistic exposure, non-salient linguistic features, as well as multiple outcome measures, we demonstrate that adult learners can learn animacy with low levels of awareness, but not case. Forty adult native speakers of English participated in the experiment. Participants were exposed to audio sentences in the artificial language paired with pictures on the computer screen for three sessions. Knowledge of animacy and case was measured with production and grammaticality judgment tests. Results demonstrated that concrete, contiguous and easily trackable L2 properties that lend themselves to distributional learning, such as animacy marking, can benefit from incidental exposure. However, more abstract L2 properties, like the morphological paradigm of case, seem not to be learnable by incidental means, and opportunities for explicit learning must be provided.
