Pidgins, narrowly defined, are auxiliary languages reserved for communication with linguistic outgroups. Although implicitly recognized as a class of languages by many linguists, there has been little systematic typological investigation of pidgins. This dissertation presents the first large-scale typological study of morphology and functional…

Research over the past two decades has reported a robust relationship between relative social status and first-person singular (FPS) pronoun use in English. For my dissertation study, I wanted to test the replicability of those findings using American Sign Language (ASL) data that I collected for this purpose. In alignment with previous work, I…

This dissertation features a relative clause island, whose status has been known to differ significantly across languages and extraction types. By conducting a series of acceptability judgment experiments with human participants, as well as measuring token-by-token surprisal values among large language models, I demonstrate the following: First,…

The initial high expectations of applied linguistic work did not endure. Applied linguistics is divided between adopting either a modernist or a postmodernist approach. Despite their relevant critique of modernism, the relativism promoted by postmodernist perspectives is an inadequate response to the challenges of the field. A non-reductionist…

Researchers often make claims regarding the importance of predictor variables in multiple regression analysis by comparing standardized regression coefficients (standardized beta coefficients). This practice has been criticized as a misuse of multiple regression analysis. As a remedy, I highlight the use of dominance analysis and random forests, a…

Identifying changing patterns of stability and variability is crucial when examining second language development (SLD) from a complex dynamic systems theory (CDST) perspective (Larsen-Freeman, 2020). By studying attractor states, or recurrent patterns of stability, light can be shed on the underlying dynamics of a complex dynamic system (van Geert…

Studies of language evolution in the lab have used the iterated learning paradigm to show how linguistic structure emerges through cultural transmission--repeated cycles of learning and use across generations of speakers . However, agent-based simulations suggest that prior biases crucially impact the outcome of cultural transmission. Here, we…

Nowadays, research in second language acquisition (SLA) is becoming increasingly interdisciplinary while many technical frontiers and research hotspots have emerged. Many studies focus on interdisciplinary topics, but few in-depth studies have been conducted on interdisciplinarity. This study examined the interdisciplinarity of SLA and the…

The Holy Qur'an, as an oral revelation by Allah to Prophet Muhammad through Gabriel, is a conveyance of the message of Almighty Allah to humanity. It takes the form of monologic argumentation which is the fountainhead of divine orientation for Muslims. Yet, the Qur'an, sometimes, offers detailed accounts of historical events and narratives in the…

Paradigms with conflicting data patterns can be difficult to learn, resulting in acquisition error. In this dissertation, I look at how paradigms are reanalyzed over time to gain insight into the factors that influence morphophonological learning. Existing models of morphophonology (e.g. Hare & Elman 1995; Albright 2002b,a, 2010) predict…

It has been claimed that the application of ordinary language philosophy has almost entirely declined since the 1970s following the development of systematic semantic theory. This is due to the allegation that it had less interest among philosophers and moved to be a historical movement. This paper presents an overview of the application of…

The data article is a digital genre that has emerged in response to new exigencies, namely, to make data more transparent and research processes more trustable and reproducible. Following White's framework of intersubjective stance, this article draws upon statistical tools and collocational and discourse analyses to examine the linguistic…

The growing concern for ethics in applied linguistics may be attributed to attempts to stem the rising incidence of ethical lapses in order to ensure that the core ethical principles of: (1) respect for persons; (2) yielding optimal benefits while minimizing harm; and (3) justice are preserved. Following a brief historical review of this topic,…

Linguistic ethnographers largely agree that engaging in self-reflexivity enables researchers to identify how their actions, subjectivities, and motivations influence research. In this article, I argue for a discourse-oriented ethnographic account as an alternative method for documenting and reporting such reflexivity. The overall goal of this…

I argue that the variation within and across contexts detailed by Shin & Miller is indicative of a broader phenomenon in which morphosyntax and the discourse context are intertwined, including elements like perspective, discourse relations, information structure, and common ground. Appealing to independent evidence highlighting the role of…
