The present study investigated the effect of classroom-based syntactic training on children's abilities to produce passive sentences. Thirty-three monolingual English children (mean age 5;2), were involved in passive-voice training based on storytelling sessions within a priming design. The training was delivered in a classroom setting, with two…

We investigated toddlers' phonological representations of common vowel-initial words that can take on multiple surface forms in the input. In French, liaison consonants are inserted and are syllabified as onsets in subsequent vowel-initial words, for example, petit /t/ éléphant [little elephant]. We aimed to better understand the impact on…

This paper revisits the longstanding observation that children produce modal verbs (e.g., must, could) with their root meanings (e.g., abilities, obligations) by age 2, typically a year or more earlier than with their epistemic meanings (e.g., inferences). Established explanations for this "Epistemic Gap" argue that epistemic language…

The current study examined the effect of speaker variability on children's cross-situational word learning (XSWL). The study also examined the role of bilingual experience and sustained attention. Forty English monolingual children and 40 Spanish-English bilingual children ages 4-7 completed a XSWL task in a Single Speaker Condition and a Multiple…

This dissertation investigates how English-speaking second language (L2) learners of Mandarin perceive, process and learn Mandarin lexical tones. While most languages use modulations in pitch (intonation) to convey meanings at the phrasal and sentential levels, a number of languages, including Mandarin, also use suprasegmental features such as…

The present research sought to explore the combined contribution of input flooding, visual input enhancement, and consciousness-raising tasks on noticing and intake of the present perfect tense among Iranian EFL learners. Using a nonrandomized control group pretest-posttest design, the researchers attempted to see if instruction could enhance the…

The present study sought to investigate the effects of meaning-focused input (MFI) and meaning-focused output (MFO) activities on willingness to communicate (WTC) of English as a Foreign Language (EFL) learners. The study aimed at exploring learners' perceptions towards the efficacy of MFO and MFI activities for developing WTC. The participants of…

The purpose of this state-of-the-art review is to provide a general overview of recent research on time distribution and second language (L2) learning with special implications for classroom settings. Several studies have been performed to examine how to best distribute the hours of L2 practice to maximize learning by comparing conditions that…

Research consistently shows that adults engaged in tutored acquisition benefit from explicit instruction in several linguistic domains. For preschool children, it is often assumed that such explicit instruction does not make a difference. In the present study, we investigated whether explicit instruction affected young learners in acquiring a…

The English past counterfactuality is difficult for non-native learners to learn and understand due to cross-language discrepancies. Oftentimes, individuals unavoidably develop the interlanguage and this language system becomes fossilized regardless of the amount of exposed time and input. The purpose of the study was twofold: (a) to examine 126…

Research has suggested that the type and frequency of learning strategies employed by successful listeners is greater than their less successful counterparts. Based on evidence that metacognitive strategies (e.g. listening-for-gist; inferring meaning) are more effective than cognitive ones (e.g. word-for-word translation), this study sought to…

The role of attention has been central to theoretical and empirical inquiries in second language (L2) acquisition. The current eye-tracking study examined how external and internal attentional manipulations (Chun, Golomb, &Turk-Browne, 2011) promote L2 grammatical development. Participants (n = 55) were exposed to Spanish direct-object…

Knowing enough vocabulary is crucial for second language learners to comprehend and produce the language. Therefore, a substantial bulk of research has aimed at finding the most effective ways to acquire new words. The Task-induced Involvement Load Hypothesis (Laufer & Hulstijn, 2001) states that vocabulary tasks are efficient when they induce…

The "wanna" facts are a classic Poverty of Stimulus (PoS) problem: "Wanna" is grammatical in certain contexts ("Who do you want PRO to play with?") but not others ("Who do you want who[strikethrough] to play with you?"). On a standard analysis, "contraction" to "wanna" is blocked by some…

Parameter setting is either precipitous (Gibson & Wexler, 1994) or it is gradual in response to input frequency (Yang, 2002, 2004). In this study, we compare these models against the empirical domain of subject and (direct) object drop in Mandarin. We conducted a corpus-based study of the speech of 47 Mandarin-speaking children aged 1;2-6;5,…
