It is often assumed that cross-linguistically more prevalent distinctions are easier to learn potentially due to their conceptual naturalness. Prior work supports this hypothesis in phonology, morphology and syntax but has not addressed semantics. This work aims to unravel the potential factors that contribute to the learnability and the…

Generalization is the ability to apply regularities to novel instances, for example, correctly guessing that the plural for the novel English word 'wug' should be 'wugs'. Early language learners make overgeneralization errors like 'mouses', applying regularities beyond their attested uses. Theories concerned with the question of how learners learn…

This dissertation presents four iterative experiments which explore the quantitative benefits of introducing linguistics to language learners. Previous work has connected exploration of linguistic with improved morale and engagement in language classrooms, as well as reduced language discrimination and validation of students' languages and…

The acquisition of a sound system is an integral component of second language (L2) communication, yet it is one of the most difficult skills to teach and is therefore largely ignored in L2 classrooms (Derwing, 2010). In laboratory settings, phonetic training studies have typically examined syllables, rather than words, with no referential meaning.…

Recent years have witnessed a strong and increasing interest in the incidental learning of second language grammar. While much of this research has focused on the acquisition of second language word order or noun-determiner systems, relatively fewer studies have examined the learning of second language morphology. Results of studies that have…

This dissertation presents results from a series of experiments investigating adult learning of an artificial language and the effects that input frequency (high vs. low token frequency), frequency distribution (skewed vs. balanced), presentation mode (structured vs. scrambled), and first language (English vs. Japanese) have on such learning.…
