This article investigates knowledge of discourse-conditioned left dislocations in the interlanguage competence in Spanish and English second language learners. Although Spanish clitic left dislocation (CLLD) and English topicalization are functionally very similar, they differ in that the former but not the latter requires the dislocated phrase to be clitic doubled. In contrast, the fronted focus (FF) construction is functionally and syntactically similar in the two languages. Two experimental studies investigated knowledge of the syntactic form and discourse appropriateness of CLLD and topicalization, using knowledge of FF as a baseline. English-native learners of Spanish were successful in acquiring CLLD as well as FF. However, Spanish-native learners of English demonstrated no knowledge of English topicalization even at near-native levels of proficiency, whereas they did well on the transferable FF. These results are examined in the light of the interface hypothesis. It is argued that construction frequency in the input and transfer from the native language, but only those two factors together, can explain the experimental results.

This study investigated the possible influence of first language (L1) collocational patterns on second language (L2) collocational processing. A lexical decision task was used to assess whether collocational patterns acceptable in the L1 but not the L2 would still be activated when processing language entirely in the L2. The results revealed no such activation. Furthermore, L2 speakers did not produce accelerated processing for control collocations that were acceptable in the L2 but not the L1. Based on these findings, we put forth some theoretical suggestions regarding recent research indicating accelerated processing for congruent over incongruent collocations. Finally, our NS control group revealed some unexpected tendencies that cannot be easily accounted for with our current understanding of L1 language processing.

The mechanisms that allow for both language-specific and universal constraints in language development are not fully understood. According to the rhythm detection hypothesis, sensitivity to rhythm is the underlying mechanism that is fundamental to language development. Support from a number of Western languages, as well as Mandarin, has led to the proposal that rhythm detection may provide a language-universal account of language development. However, claims of universality may be premature because most research has addressed reading (rather than language) development, only a small number of languages have been investigated, and pitch is a better predictor of reading than rhythm in Mandarin children. Therefore, we examined language development using a narrative story-retelling task in children who speak Cantonese (a more complex tone inventory than Mandarin) and also assessed temporal and pitch-based auditory abilities to consider whether temporal processing drives development in a tone language. Both temporal and pitch abilities correlated with language development, but only pitch explained unique variance in language after age. The findings support the role of basic auditory processing mechanisms in language development, but they extend beyond the rhythm detection hypothesis by demonstrating that the fundamental cues for development are dependent on the specific processing demands of each language, rather than being universal.

Twenty-four mothers and their preschool children with language impairment participated in two 12-min sessions of toy play and book reading that were transcribed to yield maternal mean length of utterance in morphemes (MLU-m), type token ratio (TTR), and maternal interaction style (directive vs. responsive). Maternal MLU-m was significantly longer during book reading than during toy play, whereas TTR was similar across contexts. In contrast, children's MLU-m was similar across contexts, whereas TTR was higher during book reading. Mothers used an eliciting style characterized by more commands and questions during toy play than during book reading. Only maternal MLU-m predicted children's expressive language skills (i.e., a composite score of two standardized language tests). The implications include sampling both book reading and play interactions because they provide differential opportunities for conversation and language productivity.

This paper investigates discourse effects on the provision of both subjects and objects and investigates whether pragmatic discourse features govern the realization/omission of both constituents alike. In an elicitation study, we examined how the discourse-pragmatic feature contrast, as applied to the subject, verb, or object of a transitive utterance affected the provision of elements in the remainder of the sentence when all elements were previously introduced. The results showed that 3.5-year-old children were more likely to realize a contrasted argument with a lexical noun but more likely to omit the argument when it was not part of a contrast, regardless of its subject or object status. This suggests that contrast presents a unifying discourse feature for argument omission in language development.

The goal of this study was to investigate whether individual difference factors influence the second language (L2) learning of children with specific language impairment (SLI) and children with typical development (TD) differently. The study focuses on tense inflection development in English L2 children. The roles of age of L2 acquisition, length of L2 exposure, and first language (L1) were examined. Twenty-four pairs of 4- and 5-year-old English L2 children with SLI and English L2 children with TD participated in the study. Children's responses on the third person singular and regular past tense probes of the Test of Early Grammatical Impairment (Rice & Wexler, 2001) were analyzed using logistic mixed regression modeling and classification procedures. For all children, those who started learning English later performed better than children who started learning English earlier, but the advantage of an older age of acquisition was particularly present in the L2 with SLI group. For children in the L2 group with TD, their accuracy with tense inflection clearly increased with longer L2 exposure, but this was not found for the L2 children with SLI. Finally, L2 children with TD were better able to transfer L1 knowledge than L2 children with SLI.

Language use and joint attention (JA) strategies were examined during interactions between francophone mothers and fathers and either their birth children (n = 10) or their internationally adopted children from China (n = 8), once when the children were 15 months old and again at 20 months, on average. Results showed that mothers engaged in more JA episodes and tended to talk more with their children than did fathers; however, this was influenced by the language-learning situation of the child. Specifically, the adoptive parents engaged more with their children than did the birth parents, and the behaviors of the internationally adopted mothers and fathers were more similar to each other than to those of the birth parents, arguably to support their children's unique language-learning situation. However, in contrast to a previous study that examined JA with adoptive mothers, the adoptive fathers’ interaction styles with their children at 15 months were not related to children's vocabularies at 20 months as has been observed for mothers.

The lexical restructuring model (LRM; Metsala & Walley, 1998) can be used to explain the development of phonological awareness (PA). According to LRM, as children's vocabularies increase, children develop a more refined lexical representation of the sounds comprising those words, and in turn children become more sensitive to the detection of specific phonemes. LRM identifies several lexical characteristics of words that influence lexical restructuring: age of acquisition (AoA), word frequency, neighborhood density, and phonotactic probability. In this study, the effects of these lexical characteristics on children's performance on PA tasks were evaluated, as well as moderation of these effects by children's oral language skills and ages, in two independent samples of preschool children who completed measures of PA and oral language. For both samples, AoA and word frequency were negatively related to PA skills, and phonotactic probability was positively related to PA skills. Children's ages and oral language skills were positive predictors of PA skills, and children's ages moderated the relations between AoA and PA skills for children in Sample 2. Children's oral language skills moderated the relations between AoA and PA skills for children in Sample 1. Implications are discussed.

We investigated whether children with dyslexia rely on derivational morphology during visual word recognition and how the semantic and form properties of morphemes influence this processing. We conducted two masked priming experiments, in which we manipulated the semantic overlap (Experiment 1) and the form overlap (Experiment 2) between morphologically related pairs of words. In each experiment, French dyslexic readers as well as reading-level matched and chronological-age matched children performed a lexical decision task. Significant priming effects were observed in all groups, indicating that their lexicon is organized around morpheme units. Furthermore, the dyslexics’ processing of written morphology is mainly influenced by the semantic properties of morphemes, whereas children from the two control groups are mainly influenced by their form properties.

Speech intelligibility in a multitalker background can be affected by the language of both the talker and the interfering speech. This study investigated whether this interaction is modulated by dialect variations of the same language. American English listeners were presented with target sentences in either their own General American English (GAE) or a different accent (Southern American English [SAE]) masked by either GAE or SAE two-talker babble at three sound to noise ratios (SNRs): +3, 0, and –3 dB. All speech materials were produced by male talkers. Across all conditions, SAE target was more intelligible than GAE. Intelligibility of either target decreased as the level of the interfering babble noise increased. Target accent interacted with masking accent: at +3 dB SNR, GAE (and not SAE) was the more effective masker. The target-masker interaction was different as listening conditions deteriorated: at 0 and –3 dB SNR, masking accent did not affect GAE target, but when the target was SAE, the SAE masker (and not GAE) was more effective. Thus, at increased noise levels, listeners benefited from the mismatch between the target and masking accents only when the target was in a nonnative accent. These results demonstrate that dialect variation can influence listeners’ performance in a multitalker environment. The apparent asymmetry in intelligibility of accents may be in part related to dialect-specific prosodic and phonetic features.

This study investigates the automatization of sentence processing using the coefficient of variation (CV), a measure of intraindividual processing stability (Segalowitz & Segalowitz, 1993). A smaller CV (i.e., standard deviation to reaction time [RT] ratio) and a positive CV-RT correlation are taken to index increased automatization. Hulstijn, Van Gelderen, and Schoonen (2009) were the first to try to validate the use of CV at the sentence level; however, they did not find any evidence for automatization in their CV analyses. Forty Korean English as a second language students (20 intermediate, 20 advanced) and 20 native speakers performed three speeded tasks in English: a semantic classification task, a sentence verification task, and a sentence construction task. The results revealed that, consistent with findings from previous word recognition studies, the CV in the sentence-level tasks decreased as participants’ proficiency level increased. Although the CV-RT correlation in the sentence verification task was not always significant, no counterevidence against Segalowitz and Segalowitz’ (1993) hypothesis was found. The sentence construction task discriminated better between groups than the sentence verification task. We argue that the CV may be a valid measure of automatization at the sentence level, provided the tasks used target lower-level processes such as word recognition, parsing, and semantic proposition formation.

The present study investigates the effects of stereotypical gender during anaphor resolution in German. The study aims at isolating the effects of gender-stereotypical cues from the effects of grammatical gender. Experiment 1 employs descriptions of typically male, female, and neutral occupations that contain no grammatical cue to the referent gender, followed by a masculine or feminine role noun, in a reaction time priming paradigm. Experiment 2 uses eye-tracking methodology to examine how the gender typicality of these descriptions affects the resolution of a matching or mismatching anaphoric pronoun. Results show a mismatch effect manifest at very early stages of processing. Both experiments also reveal asymmetries in the processing of the two genders suggesting that the representation of female rather than male referents is more flexible in counterstereotypical contexts. No systematic relation is found between eye movements and individual gender attitude measures, whereas a reliable correlation is found with gender typicality ratings.

The current study examines in depth how two types of form-focused instruction (FFI), which are FFI with and without corrective feedback (CF), can facilitate second language speech perception and production of /ɹ/ by 49 Japanese learners in English as a Foreign Langage settings. FFI effectiveness was assessed via three outcome measures (perception, controlled production, and spontaneous production) and also according to two lexical contexts (trained and untrained items). Two experimental groups received 4 hr of FFI treatment to notice and practice the target feature of /ɹ/ (but without any explicit instruction) in meaningful discourse. A control group (n = 14) received comparable instruction in the absence of FFI. During FFI, the instructors provided CF only to students in the FFI + CF group (n = 18) by recasting their mispronunciations of /ɹ/, while no CF was provided to those in the FFI-only group (n = 17). Analyses of pre- and posttests showed that FFI itself can sufficiently promote the development of speech perception and production of /ɹ/ and the acquisitional value of CF in second language speech learning remains unclear. The results suggest that the beginner learners without much phonetic knowledge on how to repair their mispronunciation of /ɹ/ should be encouraged to learn the target sound only through FFI in a receptive mode without much pressure for modified output.

It has been suggested that the language problems encountered in specific language impairment (SLI) arise from basal ganglia abnormalities that lead to impaired procedural memory. However, recent serial reaction time (SRT) studies did not reveal any differences between the SLI and typically developing (TD) groups on the measures of procedural memory linked to visual sequence learning. In this paper, 16 children with and without SLI were compared on two versions of SRT tasks: a visual task and an auditory one. The results showed that children with SLI were as fast as their TD peers in both modalities. All of the children obtained similar specific sequence learning indices, indicating that they were able to detect regularities in both modalities. Although children with SLI were as accurate as their TD peers for the visual SRT task, they made more errors than their TD peers in auditory SRT conditions. The results indicate that, in relation to procedural memory, the core of the impairment in SLI is not linked to difficulties in the detection of regularities. We argue that when children with SLI present some difficulties, the children's weaknesses might depend on the type of processing involved (e.g., tasks involving auditory sequences).

The study explored the contribution of two aspects of inflectional morphological awareness, verb inflection and noun–adjective inflection, to word reading and reading comprehension in the Greek language, which is an orthographically transparent language. Participants (120 first graders, 123 second graders, 126 third graders) were given two oral language experimental tasks of inflectional morphological awareness. Furthermore, phonological awareness, receptive vocabulary, expressive vocabulary, decoding, and reading comprehension were evaluated. It was revealed that noun–adjective inflectional morphology contributed significantly to decoding only in first grade, while verb inflectional morphology had a significant contribution to reading comprehension in third grade. It is interesting that inflectional morphological awareness did not predict reading skills for second graders. Phonological awareness was a firm predictor of word reading in all grades and made a unique contribution in Grades 2 and 3. Finally, in all grades, receptive vocabulary was a steady predictor of reading comprehension, whereas expressive vocabulary predicted only first-grade reading comprehension. It is suggested that inflectional morphological awareness may be an important predictor of early reading in a language with a shallow orthography and a rich morphology.
