In language acquisition, writing is the most challenging skill that English learners must master. Students often struggle at the beginning of their writing process with idea generation. Due to students' low academic achievement and their struggles, online mind mapping is suggested as a useful tool to support language students' brainstorms and idea…

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…

Language learners need to map a continuous, multidimensional acoustic signal to discrete abstract speech categories. The complexity of this mapping poses a difficult learning problem, particularly for second language learners who struggle to acquire the speech sounds of a non-native language, and almost never reach native-like ability. A common…

This study revisited L2 morpheme development order among Korean young learners of English. Taking into account the spirit of the current English curriculum in South Korea, the current study examined L2 morpheme development from two different perspectives: accuracy and fluency aspects. In the field of second language development, many studies have…

The present research examines whether adults who learn a second language (L2) mainly in a classroom setting can develop linguistic representations that are qualitatively similar to those of native speakers for linguistic content that is not explicitly taught in the classroom. It does so by focusing on the domains of speech processing and speech…

Numbers are ubiquitous in life. At the same time, the symbols for numbers are highly abstract and their visual appearance does not carry any direct relation to their magnitude. This poses an important question for researchers interested in how numbers are mentally processed. Whereas research on numeric cognition suggests that culturally based…

Despite extensive research on language acquisition, our understanding of how people learn abstract linguistic structures remains limited. In the phonological domain, we know that perceptual reorganization in infancy results in attuning to native language (L1) phonetic categories and, consequently, in difficulty discriminating and learning…

While attentional models of SLA postulate attention as crucial for learning to take place (e.g., Robinson, 1995b; Schmidt, 1990, 2001; Tomlin & Villa, 1994), the role that awareness or lack thereof plays remains debatable. Indeed, the studies that have empirically addressed the construct of unawareness reveal conflicting results (e.g.,…

This dissertation provides a comprehensive analysis of the L2 acquisition of Spanish psych-verbs (e.g. "gustar" "to like") across four different proficiency levels. In particular, psych-verbs constitute a testing ground for the predictions of the Interface Hypothesis (Sorace and Filiaci, 2006; Tsimpli, Sorace, Heycok &…

This dissertation investigates second language (L2) development in the domains of morphosyntax and semantics. Specifically, it examines the acquisition of definiteness and specificity in Russian within the Feature Re-assembly framework (Lardiere, 2009), according to which the hardest L2 learning task is not to reset parameters but to reconfigure,…

This dissertation investigates the ways in which experience with lexical tone influences the perception of musical melody, and how musical training influences the perception of lexical tone. The central theoretical basis for the study is a model of perceptual learning, Reverse Hierarchy Theory (Ahissar et al., 2009), in which cognitive processes…

This dissertation is focused on analyzing phonological contact between Slavic and non-Slavic languages in southeastern and northeastern Europe, with the particular goal of describing how the social context of language contact interacts with linguistic factors to shape the outcome of contact-induced change. On the basis of case studies drawn from…
