Purpose: Adults recognize words that are acquired during childhood more quickly than words acquired during adulthood. This is known as the Age of Acquisition (AoA) effect. The AoA effect, according to the integrated account, manifests in tasks necessitating greater semantic processing and in tasks with arbitrary input-output mapping. Compound…

This dissertation examines whether and how psycholinguistic priming, and social knowledge are integrated in the identification of sociolinguistic variants. Using the English variable (ING), the alternation between -ing and -in' (e.g. thinking vs. thinkin') as a testing ground, this dissertation probes whether and how individuals utilize…

This study examines nominal derivational affixes in a multilingual practice in the Philippines involving Hokkien, Tagalog, and English called Lánnang-uè. A feature of this practice is the systematic combination of affixes and roots (henceforth, 'system'). Certain morphological combinations (e.g. Tagalog prefixes + English root) are used frequently…

Languages exhibit variation at all linguistic levels, from phonology, to the lexicon, to syntax. Importantly, that variation tends to be (at least partially) conditioned on some aspect of the social or linguistic context. When variation is unconditioned, language learners regularize it -- removing some or all variants, or conditioning variant use…

This study tests the Competing Systems Hypothesis (CSH) as applied to adult second language acquisition of aspect in Spanish. The CSH purports that differences among tutored and untutored learners result from competition between one system of underlying grammatical knowledge and another of learned metalinguistic knowledge in tutored learners…

According to previous research, speakers of European languages parse regularly-inflected, morphologically-complex words into stems and grammatical affixes during word recognition. In contrast, some studies suggest that late second language (L2) learners do not. We ask how these types of words are processed in Arabic, a language whose primary…

This thesis examines whether native, heritage, and L2 speakers of Spanish engage a morphological layer of representation in the processing of inflected words, and whether they do so with both regularly- and irregularly-inflected words. Also examined is whether this tendency towards compositional (i.e. morphological rule-based) processing is…

In a variety of domains, adults who are given input that is only partially consistent do not discard the inconsistent portion (regularize) but rather maintain the probability of consistent and inconsistent portions in their behavior (probability match). This research investigates the possibility that adults probability match, at least in part,…

The study investigated the acquisition of Modern Standard Arabic (MSA) by second language (L2) learners and by heritage speakers of the colloquial varieties of Arabic. The study focused on three questions: (1) whether heritage speakers who enroll in college-level elementary MSA classes have an advantage over their L2 counterparts, (2) whether any…

The study examined the acquisition of two morphological procedures of noun pluralization in Palestinian Arabic: "Sound Feminine Plural" (SFP) and "Broken Plural" (BP). We tested if noun pluralization was affected by (1) the type of morphological procedure, (2) the degree of familiarity with the singular noun stem, and (3) the…

In this paper we investigate the effect of variable input on the acquisition of grammar. More specifically, we examine the acquisition of the third person singular marker -s on the auxiliary "do" in comprehension and production in two groups of children who are exposed to similar varieties of English but that differ with respect to adult…

The present article provides an exploration of ultimate attainment in second language (L2) and its limitations. It is argued that the question of maturational constraints can best be investigated when the reference population is bilingual and exposed on a regular basis to varieties of their first language (L1) that show cross-linguistic influence.…

At one time, academic inquiries into the relationship between socioeconomic class and language acquisition were commonplace, but the past 20 years have seen a decrease in work that focuses on the intersection between class and early language learning. Recently, however, against the backdrop of the No Child Left Behind legislation in the United…
