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…

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…

It has long been recognized that there is a natural dependence between theories of knowledge representation and theories of knowledge acquisition, with the idea that the right knowledge representation enables acquisition to happen as reliably as it does. Given this, a reasonable criterion for a theory of knowledge representation is that it be…

Generative approaches to language have long recognized the natural link between theories of knowledge representation and theories of knowledge acquisition. The basic idea is that the knowledge representations provided by Universal Grammar enable children to acquire language as reliably as they do because these representations highlight the…

Recent studies in the acquisition of a second language (L2) phonology have revealed that orthography can influence the way in which L2 learners come to establish target-like lexical representations (Escudero et al., 2008, 2014; Escudero and Wanrooij, 2010; Showalter, 2012; Showalter and Hayes-Harb, 2013). Most of these studies, however, involve…

While considerable dialectal variation exists, almost all varieties of Spanish exhibit some sort of alternation in terms of the palatal obstruent segments. Typically, the palatal affricate [??] tends to occur in word onset following a pause and in specific linear phonotactic environments. The palatal fricative [?] tends to occur in syllable onset…

There is growing interest in learners' cognitive capacities to process a second language (L2) at first exposure to the target language. Evidence suggests that L2 learners are capable of processing novel words by exploiting phonological information from their first language (L1). Hearing adult learners of a sign language, however, cannot fall back…

A growing research line documents significant bivariate correlations between individual measures of speech perception gathered in infancy and concurrent or later vocabulary size. One interpretation of this correlation is that it reflects language specificity: Both speech perception tasks and the development of the vocabulary recruit the…

Second language (L2) learners of tone languages do not perceive and produce the different tones of the target language with equal ease. The most common explanation for these asymmetries is that acoustically salient tones are the easiest to learn. An alternative explanation is that tones are easiest to learn when they are highly frequent in the…

To acquire one's native phonological system, language-specific phonological categories and relationships must be extracted from the input. The acquisition of the categories and relationships has each in its own right been the focus of intense research. However, it is remarkable that research on the acquisition of categories and the relations…

The Pacific Coast Athabaskan (PCA) languages are part of the Athabaskan language family, one of the most geographically widespread in North America. Over a millennium ago Athabaskan-speaking groups migrated into northwestern California and southwestern Oregon from a northern point of origin several hundred miles away, but even after several…

It is argued that new phonological features can be acquired in second languages, but that both feature acquisition and feature re-assembly are affected by the robustness of phonetic cues in the input.

The dissertation study aims to contribute mainly to the field of loanword phonology in general and particularly to Indonesian and its phonology that are rarely studied to date. The study investigates what consonantal and syllabic repair strategies are employed by Indonesian in adapting Arabic and Dutch loanwords, whether these adaptation…

This thesis has two broad goals. The first is to contribute to the study of Arabic phonology particularly syllable structure and syllabification. This will be achieved through examining phenomena related to syllable structure and syllabic weight such as syllabification, stress assignment, epenthesis, syncope, and sonority in three different…
