In this study we show that the perception of lateral variants by Puerto Rican listeners changes according to who the listener believes is speaking. Puerto Rican listeners heard sentences with target words featuring either rhotic [voiced alveolar tap or flap] or lateral [l] (amo[voiced alveolar tap or flap] -- amo[l]) codas, a sociophonetic…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

This study examines whether pronunciation instruction can improve listening comprehension in a second language. At the most basic level, listening comprehension involves the perception of individual sounds and sound contrasts, a process that is known to be related to production, or pronunciation, within the L2 phonological system. As improving…

This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…

Spanish native speakers are known to pronounce onset /sC/ clusters in English with a prothetic vowel, as in "esport" for sport, due to their native language phonotactic constraints. We assessed whether accurate production of e.g. "spi" instead of "espi" was related to accurate perceptual discrimination of this…

Purpose: The intelligibility of an accent strongly depends on the specific talker-listener pairing. To explore the causes of this phenomenon, we investigated the relationship between acoustic-phonetic similarity and accent intelligibility across native (1st language) and nonnative (2nd language) talker-listener pairings. We also used online…

In this dissertation, I investigated how cognitive resources as well as formal, and informal language experience impact language learning in two studies. In the first study (Chapter 2), I examined the learning of Spanish grammatical gender by Chinese international students who were studying abroad in the US. The goal of that study was to uncover…

Studies of the acquisition of the lenited allophones of Spanish voiced stops have traditionally focused on the production (Lord, 2010; Rogers & Alvord, 2014; Zampini, 1994), but not on the perception of these sounds. This pilot study examines relationships between (a) learner proficiency and perception of target sounds; (b) learner perception…

Duration-based auditory grouping preferences are presumably shaped by language experience in adults and infants, unlike intensity-based grouping that is governed by a universal bias of a loud-soft preference. It has been proposed that duration-based rhythmic grouping preferences develop as a function of native language phrasal prosody.…

Although previous research has documented the relationship between voice-onset time (VOT) and the production of foreign accent in English and Spanish, less is known about the role of this cue in perception. VOT refers to the aspiration that occurs between the release of a stop consonant and the beginning of the following segment. In Spanish and…

Purpose: The present study investigated the effects of supporting both English and Spanish on language outcomes in bilingual children with hearing loss (HL) who used listening devices (cochlear implants and hearing aids). The English language skills of bilingual children with HL were compared to those of their monolingual English-speaking peers'…

Previous research has suggested that training on a musical instrument is associated with improvements in working memory and musical pitch perception ability. Good working memory and musical pitch perception ability, in turn, have been linked to certain aspects of language production. The current study examines whether working memory and/or pitch…

We probed simultaneous French-Spanish bilinguals for the perception of Spanish lexical stress using three tasks, two short-term memory encoding tasks and a speeded lexical decision. In all three tasks, the performance of the group of simultaneous bilinguals was intermediate between that of native speakers of Spanish on the one hand and French late…

Purpose: Bilingual aphasia generally affects both languages. However, the age of acquisition of the second language (L2) seems to play a role in the anatomo-functional correlation of the syntactical/grammatical processes, thus potentially influencing the L2 syntactic impairment following a stroke. The present study aims to analyze the influence of…

During the first year of life, infants begin to have difficulties perceiving non-native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non-segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a…
