Final Report Abstract

Extensive research has shown that statistical learning (SL) - succinctly defined as the discovery of structure by way of statistical properties of the input - is a fundamental mechanism that shapes basic aspects of perception and action. In the field of language learning, SL has been shown to boost the acquisition of knowledge across all components of the linguistic system, from the acquisition of properties of speech as well as the graphotactic and morphological regularities of written words to complex grammatical structures. Moreover, there is growing evidence of a tight coupling between individual differences in SL abilities and variability in native language learning and processing, in both child and adult populations. However, while this research has been expanding rapidly in recent years, much less is known about the role of SL in second-language (L2) learner populations. The initial phase (P1) of the current project has significantly advanced our understanding of SL and its connection to Second Language Learning and Processing (L2LP). This was achieved through a systematic exploration of the extent to which L2 learners can assimilate linguistic knowledge by analyzing statistical regularities inherent in the L2 input. The outcomes of P1 have laid the groundwork for a more comprehensive and integrated approach, setting the stage for addressing pivotal theoretical and methodological questions in the subsequent phase (P2). The results from P2 have illuminated intricate interconnections between SL abilities and diverse factors related to L2 experience, as well as cognitive-affective individual differences, delineating their relative impact on L2LP. On a methodological level, innovative processing-based measures were introduced to assess SL abilities, and these were effectively aligned with L2 performance measures based on ecologically valid data. The project synthesized empirical evidence from a series of corpus-based and behavioral experimental studies, offering a profound understanding of the intricate dynamics between SL and inter-individual differences factors influencing L2 production and comprehension. By integrating SL and implicit learning paradigms, the project investigated both the phenomenological aspects and learning consequences of SL knowledge. Furthermore, it underscored the importance of harnessing big data, natural language processing, and machine/deep learning, demonstrating their combined efficacy in gaining new insights and fostering a more profound understanding of language learning on a large scale. Collectively, the findings from this project have provided valuable insights into the fundamental mechanisms underlying language learning and processing. The findings on individual differences are of central importance for contemporary theories on the acquisition, processing and use of language and have direct relevance for L2 instruction.
