Why do adults seem to struggle more than children in learning a second language, despite being better at a range of other cognitive skills? The source of L1-L2 differences in language learning is one of the most debated topics in the study of language. One hypothesis is that L1-L2 differences are primarily experience-based, with language learning…

Wisconsin Walloon is a heritage dialect of a threatened language in the langue d'oïl family that originated in southern Belgium and expanded to northeastern Wisconsin, USA in the mid-1850s. Walloon-speaking immigrants formed an isolated agricultural community, passing on and using the language for the next two generations until English became the…

This paper sets out to peruse the role of various theories or more precisely, hypotheses invoked in second language acquisition (SLA) research by surveying three empirical studies pertaining to the critical period hypothesis in the SLA of phonetics and phonology. In particular, the three studies reviewed are titled in chronological order as (1)…

Grounded or embodied cognition research has employed body-object interaction (BOI; e.g., Pexman et al., 2019) ratings to investigate sensorimotor effects during language processing. We investigated relationships between BOI ratings and nonarbitrary statistical mappings between words' phonological forms and their syntactic category in English;…

This study is concerned with comparing the pronunciation in Southern Welsh, a Celtic language, and Cockney, an English dialect, regarding the place of articulation. The study uses a comparative method to shed light on the similarities and differences between the two accents. The data were collected from YouTube videos of speakers of Southern Welsh…

Nearly half a century has passed since Philippine educator Teodoro Llamzon discovered the Remontado language, which would be introduced to the world in a master's thesis written by his student Pilar Santos. Although data from the wordlists they collected have been included in subsequent publications by several other authors, no one had revisited…

An ongoing debate in phonology concerns the extent to which the phonological typology is shaped by synchronic learning biases. The two best-studied types of synchronic bias are complexity bias, a bias against formally complex patterns, and substantive bias, a bias against phonetically unnatural patterns. While most previous work has focused on…

This dissertation investigates a typologically rare linguistic phenomenon found in Irish from three different perspectives: how it challenges phonological theory, how it is used by contemporary speakers, and how its written representation affects its acquisition. Initial consonant mutation (ICM), as it appears in the Celtic languages, is known to…

Beginning with the classic work of Shepard, Hovland, & Jenkins (1961), Type II visual patterns (e.g., exemplars are large white squares OR small black triangles) have held a special place in investigations of human learning. Recent research on Type II "linguistic" patterns has shown that they are relatively frequent across languages…

The concept of an output-driven map formally characterizes an intuitive notion about phonology: that disparities between the input and the output are introduced only to the extent necessary to satisfy restrictions on outputs. When all of the grammars definable in a phonological system are output-driven, the implied structure provides significant…

The Possible Word Constraint, or PWC, is a speech segmentation principle prohibiting to postulate word boundaries if a remaining segment contains only consonants. The PWC was initially formulated for English where all words contain a vowel and claimed to hold universally after being confirmed for various other languages. However, it is crucial to…

Foreign-accented speech is generally harder to understand than native-accented speech. This difficulty is reduced for non-native listeners who share their first language with the non-native speaker. It is currently unclear, however, how non-native listeners deal with foreign-accented speech produced by speakers of a different language. We show…

Automated alignment of transcriptions to audio files expedites the process of preparing data for acoustic analysis. Unfortunately, the benefits of auto-alignment have generally been available only to researchers studying majority languages, for which large corpora exist and for which acoustic models have been created by large-scale research…

Adult second language (L2) learners often experience difficulty with novel L2 phonological contrasts, limiting their ability to establish contrastive lexical representations of L2 words. It has been demonstrated that the availability of orthographic input (OI), and variables interacting with OI, can shape the inferences learners make about L2…

This paper creates a novel link between research on linguistics and education by discussing what we know about the sound system of heritage language users of Spanish and how these findings can inform practices implemented in heritage Spanish courses in the USA. First, we provide an overview of terminology associated with heritage language…
