In this dissertation, I establish a research program that uses computational modeling as a testbed for theories of phonological learning. This dissertation focuses on a fundamental question: how do children acquire sound patterns from noisy, real-world data, especially in the presence of lexical exceptions that defy regular patterns? For instance,…

The present dissertation reports two experiments that examine implicit and explicit language learning methods and their impacts on early vocabulary, grammar, and phonological acquisition, in addition to working memory, proactive/reactive control, and fluid intelligence, as well as learner motivation. Experiment 1 investigated adult L2 acquisition…

This dissertation investigates the soft typology of phonological patterns. By studying the types of patterns observed in the world's languages, we can do more than determine what is attested and what is unattested, or what is possible and what is impossible, but discover a wide range of more gradient phenomena. Phonological patterns range from…

This study aims to identify similarities in morphological, phonological, lexical, and syntactical aspects between Arabic and English child language. It seeks to understand how children develop grammar at different stages, adhering to the rules acquired at each stage. This research analyzes YouTube videos featuring Arabic and English-speaking…

Hudson Kam (2018) examined whether learning of a particular aspect of language that adults are known to have difficulty with (grammatical gender) could be improved by manipulating the learning experience of adults so that it was more like that of infants. Specifically, based on likely differences between adult and child learners' experiences as…

The current study establishes the reliability of the Holy Qur'an as one of the earliest treatise on language acquisition by humans. This is not to say that it is a scientific treatise: Rather what we know as modern 'knowledge' finds mention in a book much older. This applies to many aspects of human life, whether they spring from scientific…

Understanding how native speakers acquire the phonological patterns in their language is a key task for the field of phonology. Numerous studies have suggested that phonological learning is a biased process: certain phonological patterns are easily accessed and learned by the speakers, while others show acquisition difficulties. These differences…

This paper explores the hypothesis that children pay more attention to phonological cues than semantic cues when acquiring grammatical patterns. In a series of artificial allomorphy learning experiments with adults and children we find support for this hypothesis but only for those learners who do not show clear signs of explicit learning. In…

Poverty of the stimulus has been at the heart of ferocious and tear-filled debates at the nexus of psychology, linguistics, and philosophy for decades. This review is intended as a guide for readers without a formal linguistics or philosophy background, focusing on what poverty of the stimulus is and how it's been interpreted, which is…

Afrikaans is a West Germanic language that originated in South Africa as a descendent of Dutch. It displays discontinuous sentential negation (SN), where negation is expressed by two phonologically identical negative particles that appear in two different positions in the sentence. The negation system is argued to be an innovation that came about…

The acquisition of a new morphological rule can be influenced by numerous factors, including the type of feedback provided during learning. The present study aimed to test the effect of different feedback types on children's ability to learn and generalize an artificial morphological rule (AMR). Two groups of eight-year-olds learned to judge and…

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…

The question of whether second languages (L2s) are best learned implicitly or explicitly has been a topic of much empirical discourse, with the majority of studies pointing to the benefits of explicit instruction when learning L2 grammar rules. However, given the focus on grammar, it is unclear how generalizable these findings are to other…

In two artificial grammar learning experiments, we tested the learnability of tonal phonotactics forbidding non-domain-final rising tones (*NonFinalR) against the phonotactics banning non-domain-final high-level tones (*NonFinalH). We propose that a firm phonetic ground drives a presumably innate inductive bias favoring *NonFinalR and against…

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…
