When acquiring a second language, learners must become able to perceive the difference between novel sounds ("discrimination") and also associate strings of sounds with distinct vocabulary items ("lexical encoding"). Recent research has questioned whether discrimination is a sufficient or necessary condition for encoding, and…

Non-adult-like linguistic behavior in children is sometimes taken as evidence for endogenous factors that drive selection of grammatical features from the child's hypothesis space of possible grammars. Analyses of English-acquiring children's productions of medial "wh"-phrases exemplify this trend in particular. We provide an alternative…

The so-called syllable position effect in speech errors has been interpreted as reflecting constraints posed by the frame structure of a given language, which is separately operating from linguistic content during speech production. The effect refers to the phenomenon that when a speech error occurs, replaced and replacing sounds tend to be in the…

We assessed the effect of bilingualism on metacognitive processing in the artificial language learning task, in 2 experiments varying in the difficulty to segment the language. Following a study phase in which participants were exposed to the artificial language, segmentation performance was assessed by means of a dual forced-choice recognition…

This study examined the relationship between children's morphological awareness and their ability to produce accurate morphological derivations in writing. Fifth-grade US students (n = 175) completed two writing tasks that invited or required morphological manipulation of words. We examined both accuracy and error, specifically errors in…

Through analyzing response latencies, errors, and self-repairs in Mandarin, this investigation explores how monolingual, bilingual, and trilingual adults process their speech production differently using cognitive control mechanisms. In this study we conducted two experiments involving speech production in Mandarin. In the two experiments, 81…

This study reports evidence of cross-linguistic influence (CLI) that surfaced from English compositions of SiSwati learners of English in Swaziland, where English is a second language. Although CLI has been studied widely in other languages, it has not been studied in SiSwati and English, and its implications for instruction are not known.…

In the current study we explored lexical, syntactic, and semantic processes during text comprehension in English monolinguals and Spanish/English (first language/second language) bilinguals with different experience in interpreting (nontrained bilinguals, interpreting students and professional interpreters). The participants performed an…

Background: Children with speech sound disorders (SSD) form a heterogeneous group who differ in terms of the severity of their condition, underlying cause, speech errors, involvement of other aspects of the linguistic system and treatment response. To date there is no universal and agreed-upon classification system. Instead, a number of…

Sentence repetition (SR) tasks have been used to measure children's expressive language skills in normal and abnormal language development, and to examine the development of the speaking skills in second language acquisition, as well as to survey the proficiency of bilingual language development. Recently, SR tasks have been recognized as a…

Han's (2009, 2013) selective fossilization hypothesis (SFH) claims that L1 markedness and L2 input robustness determine the fossilizability (and learnability) of an L2 feature. To test the validity of the model, a pseudo-longitudinal study was designed in which the errors in the argumentative essays of 52 Iranian EFL learners were identified and…

This dissertation investigates the acquisition of early verb inflection in child Slovenian from morphosyntactic and morphophonological perspectives. It centers on the phenomenon of root nonfinites, particularly the patterns of omission and substitution errors in verb inflection marking. It argues that every acquisition model needs to account…

Lexical-semantic access and retrieval was examined in 15 adults diagnosed with schizophrenia and matched controls. This study extends the literature through the inclusion of multiple examinations of lexical-semantic production within the same patient group and through correlating performance on these tasks with various positive and negative…

The present paper looks at the growing population of Russian heritage speakers from a linguistic and psycholinguistic perspective. The study attempts to clarify further the notion of heritage language by comparing the linguistic performance of heritage speakers with that of monolinguals and second language learners. The amount of exposure to…

Environmentally contaminated speech errors (irrelevant words or phrases derived from the speaker's environment and erroneously incorporated into speech) are hypothesized to occur at a high level of speech processing, but with a relatively late insertion point. The data indicate that speech production processes are not independent of other…
