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,…

This study investigates the phonological awareness of a Turkish monolingual and a Turkish-English bilingual child in Turkish. As a case study, the main focus of this study is to explore whether a bilingual advantage exists in phonological processing. Theories of bilingualism and empirical data led to the prediction that the bilingual participant…

The aim of the present study was to examine the interplay of morphological configuration switching and language switching. The morphological configuration is present in word-formation whenever a word contains more than one free morpheme. The morphological configuration is variable both within and between languages for example in two-digit number…

The present study aims to investigate the role of L1 transfer effects on L2 sentence processing strategies during the interpretation of relative clause (RC) attachment ambiguities. The main body of the study is divided into two sections. The first section describes Experiment 1, which is designed to test the resolution of RC attachment ambiguities…

Language modeling is one of many problems in language processing that have to grapple with naturally high ambient dimensions. Even in large datasets, the number of unseen sequences is overwhelmingly larger than the number of observed ones, posing clear challenges for estimation. Although existing methods for building smooth language models tend to…

This paper demonstrates systematic cross-linguistic differences in the electrophysiological correlates of conflicts between form and meaning ("semantic reversal anomalies"). These engender P600 effects in English and Dutch (e.g. [Kolk et al., 2003] and [Kuperberg et al., 2003]), but a biphasic N400--late positivity pattern in German (Schlesewsky…

This work is a systematic, cross-linguistic examination of speech errors in English, Hindi, Japanese, Spanish and Turkish. It first describes a methodology for the generation of parallel corpora of error data, then uses these data to examine three general hypotheses about the relationship between language structure and the speech production…

Visual information from the face is an integral part of speech perception. Additionally, orthography can play a role in disambiguating the speech signal in nonnative speech. This study investigates the effect of audiovisual speech information and orthography on nonnative speech. Particularly, orthographic depth is of interest. Turkish transparent…

Two experiments are reported testing bilinguals' recall of words presented in one of two languages and under several conditions. Performance was best when the individuals had seen the word itself, less good when they had seen the other language's equivalent, and equally or least good when they had seen neither. (MSE)

Children aged 2;0 to 4;4, including native speakers of English, Italian, Serbo-Croatian, and Turkish, were asked to demonstrate causative statements by acting them out with toy animals and dolls. The major analysis focused on the total number of correct acting-out responses and the way this score related to several variables. Performance improved…
