This study investigates whether and how individual differences modulate the adult second language (L2) processing of syntactic ambiguities. In a linear mixed regression analysis, we test how proficiency, working memory, reading speed, automaticity in lexical access, and grammatical integration ability affect the resolution of temporary object–subject ambiguities in L2 English. The results from 75 first language German advanced learners attest that individual differences in syntactic integration ability modulate the reliance on morphosyntactic and plausibility information. Similar to native speakers, L2 learners are found to adopt two different routes in L2 processing. The findings highlight the role of individual differences and qualify previous generalizations about the relative use of morphosyntactic and other types of information in L2 processing.

On account of both their functional and their morphosyntactic characteristics, relative clauses are often viewed as indicators of complexity in child language. Morphosyntactic properties of Turkish make use of particularly arduous relative clauses in spontaneous early discourse. A matching sticker selection task was used to determine whether Turkish-learning 3- and 4-year-olds can be trained to use subject relative clauses and uniquely identifying constructions. Upon their selection of the accurate sticker, the children were exposed to relative clause constructions (relative clause condition), sentences with demonstrative pronouns (demonstrative noun phrase condition), or a general approval (positive feedback condition). The number of relative clauses increased from pretest to posttest only in the relative clause condition; the rate of using adequately discriminating forms increased in all the three conditions, albeit with a steeper increase in the relative clause condition. The results are discussed in the framework of both structural and pragmatic priming.

This study investigated the role of length and complexity on sentence repetition in children with dyslexia and typical readers. Length and complexity each had independent effects on sentence repetition, and children with dyslexia performed more poorly than typical readers. This group effect was attributable to individual differences in language rather than memory skills. Error analyses revealed that content words (specifically adjectives) were more likely to be omitted in longer than in shorter sentences independent of complexity. In complex sentences, function words (specifically prepositions) were the most vulnerable to errors, particularly for a subgroup of children with dyslexia who had oral language difficulties. It is proposed that deficits in sentence repetition are indicative of language difficulties in children with dyslexia.

In second language (L2) research and testing, measures of oral fluency are used as diagnostics for proficiency. However, fluency is also determined by personality or speaking style, raising the question to what extent L2 fluency measures are valid indicators of L2 proficiency. In this study, we obtained a measure of L2 (Dutch) proficiency (vocabulary knowledge), L2 fluency measures, and fluency measures that were corrected for first language behavior from the same group of Turkish and English native speakers (N = 51). For most measures of fluency, except for silent pause duration, both the corrected and the uncorrected measures significantly predicted L2 proficiency. For syllable duration, the corrected measure was a stronger predictor of L2 proficiency than was the uncorrected measure. We conclude that for L2 research purposes, as well as for some types of L2 testing, it is useful to obtain corrected measures of syllable duration to measure L2-specific fluency.

Morphological awareness, which is an understanding of how words can be broken down into smaller units of meaning such as roots, prefixes, and suffixes, has emerged as an important contributor to word reading and comprehension skills. The first aim of the current study was to investigate the contribution of morphological awareness independent of phonological awareness and decoding to the reading comprehension abilities of adults with low literacy. Results indicated that morphological awareness was a significant unique predictor of reading comprehension. A second aim of the study was to investigate the processing of morphologically complex words of adults with low literacy in both an oral reading passage and a single-word naming task. Adults’ accuracy and response times were measured on different types of morphologically complex words and compared with control words matched on frequency in both the passage and the naming tasks. Results revealed that adults were vulnerable to morphological complexity: they performed more accurately and faster on matched control words versus morphologically complex word types. The educational implications for Adult Basic Education programs are discussed.

This article argues that “animacy” in the context of attributive psych adjectives can be subcategorized into “human,” “human by metonymy,” and “animate” and that these subcategories play a role for Chinese speakers acquiring English. A study that involved an acceptability judgment test found that, in contrast to a group of native controls, the second language (L2) speakers misuse adjectival –ed for adjectival –ing with animate nouns and adjectival –ing for adjectival –ed with human by metonymy nouns, indicating that L2 speakers appeal to an “animacy hierarchy” in determining the meanings of English psych adjectives. There is no evidence in the target language input for such a hierarchy, so the results are consistent with the view that these L2 learners are drawing on universal properties of thematic organization.

Although a relationship between morphological awareness and vocabulary has been widely observed, questions remain about the direction of that relationship. This longitudinal study explores the temporal relationship between morphological awareness and vocabulary among monolingual English-speaking children. Participants were 100 children tested in Grades 2 and 3. We evaluated morphological awareness and vocabulary in both grades, along with phonological awareness, word reading, pseudoword reading, and nonverbal reasoning. Cross-lagged regression analyses with autoregressive controls assessed the temporal relationship between morphological awareness and vocabulary; morphological awareness at Grade 2 predicted change in vocabulary between Grades 2 and 3, but vocabulary did not predict change in morphological awareness. The results add to our understanding of the relationship between these two developing skills.

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.

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.

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.

Wh-words in Mandarin Chinese exhibit quantificational variability. Aside from a typical interrogative reading, wh-words can also have an existential indefinite reading or a universal reading. Which reading it is depends on the linguistic environments in which they occur. The present study investigates Mandarin-speaking children's sensitivity to the linguistic environments for the noninterrogative use of wh-words: the existential reading and the universal reading. The results show that young children exhibited adultlike sensitivity to the licensing environments for the noninterrogative use of wh-words. Given the difficulty that children may have in using the input data to learn the interpretation of wh-words and the early emergence of this knowledge, we propose that the licensing mechanism for the noninterrogative use of wh-words is innate.

This study examined the relationship between performance on standardized measures of language proficiency and conversational measures of the same features used in academic discourse among 24 monolingual and 25 bilingual kindergarteners. Academic discourse performance was considered for both its linguistic and its genre features in two discourse forms: narrative and explanation. Bilinguals performed more poorly than monolinguals on standardized measures of language proficiency, yet they performed similarly to monolinguals in the discourse-based linguistic and genre features. Moreover, genre features were more strongly related to linguistic features assessed through discourse than to standardized tests of these same features. These findings indicate that standardized measures of language proficiency underrepresent the abilities of bilingual children and that children's second language proficiency may be more accurately reflected in conversation.

The aim of the present study was to investigate changes in voicing identification, discrimination, and categorical perception induced by identification training centered on three different training values. One group of French-speaking adults was trained across a universal auditory boundary (−30 ms voice onset time), and two other groups were trained across arbitrary boundaries (−45 or −60 ms voice onset time). A control group did not receive any training. The results showed that both the −30 and the −45 training groups exhibited a 10 ms shift in the identification boundary. Moreover, for the −30 training group, discrimination and categorical perception changed around the French phonological boundary. These results illustrate the possibility of modifying the French phonological perception after short-time training, particularly when centered on a universal boundary. However, training only had limited effects and even strengthened the phonological boundary, congruent with the hypothesis that this boundary is acquired by a perceptual “coupling” between universal boundaries.

Expression of spatial motion shows wide variation as well as patterned regularities across the world's languages (Talmy, 2000), and events involving the traversal of a spatial boundary impose the tightest typological constraints in the lexicalization of motion, providing a true test of cross-linguistic differences. Speakers of verb-framed languages are required by their language not to use manner verbs in marking the change of location across boundaries (Aske, 1989). Here we test the strength of the boundary-crossing constraint and ask how speakers convey motion events when the constraints imposed by the experimental task are at odds with the constraints imposed by their native language. We address this question by comparing adult speakers’ description of motion scenes that involve the traversal of a spatial boundary in two typologically distinct languages: English and Turkish. Using an experimental paradigm that imposes competing demands with the semantic structure of Turkish, we compare Turkish speakers’ description of boundary-crossing scenes to that of English speakers. We find strong cross-linguistic differences in speakers’ verb choice (manner vs. path) and event segmentation (one vs. many), suggesting that boundary-crossing constraint can serve as a reliable test to detect the typological class of a language.
