This study investigates whether developmental dyslexia involves an impairment in implicit phonological representations, as distinct from orthographic representations and metaphonological skills. A group of adults with dyslexia was matched with a group with no history of speech/language/literacy impairment. Tasks varied in the demands made on (implicit) phonological representations versus metalinguistic analysis/manipulation, and controlled the contribution of phonological versus orthographic representations by including both a segmental and an equivalent suprasegmental (nonorthographic) version of each task. The findings show a dissociation between metaphonological skills and implicit phonological representations, with the dyslexic group impaired in metaphonological manipulation skills in both segmental and suprasegmental tasks, but not in implicit knowledge of phonological contrasts.

This study examined the relation between young English language learners’ (ELL) native oral language skills and their language input in transitional bilingual education kindergarten classrooms. Spanish-speaking ELLs’ (n = 101) Spanish expressive language skills were assessed using the memory for sentences and picture vocabulary subtests of the Woodcock Language Proficiency Battery—Revised. Samples of transitional bilingual education teachers’ (n = 21) speech were recorded and coded for syntactic complexity and vocabulary usage. Results revealed considerable variation in ELLs’ language scores, with overall performance below the normative sample. There was also wide variation in teachers’ speech across classrooms. Hierarchical linear modeling revealed that gains in ELLs’ expressive language skills were positively related to the diversity of teachers’ vocabulary and teachers’ syntactic complexity. These findings suggest that the quality of teachers’ language input, not just the quantity of their input, plays a significant role in the language learning trajectories of ELLs.

This study investigated the direct and indirect roles of morphological awareness reading comprehension for Spanish-speaking language minority learners reading in English. Multivariate path analysis was used to investigate the unique contribution of derivational morphological awareness to reading comprehension as well as its indirect contributions via three hypothesized mediators for students in sixth, seventh, and eighth grade (N = 101). Results indicated a significant unique contribution of morphological awareness, controlling for phonemic decoding, listening comprehension, reading vocabulary, word reading fluency, and passage reading fluency. Results further indicated significant indirect contributions of morphological awareness via reading vocabulary and passage fluency, but not via word reading fluency. Findings suggest that morphological awareness may play multiple important roles in second-language reading comprehension.

Following an extensive overview of the subject, this study explores the relationships between second-language (L2) explicit/implicit knowledge sources, embedded in the declarative/procedural memory systems, and L2 working memory (WM) capacity. It further examines the relationships between L2 reading comprehension and L2 WM capacity as well as those between L2 reading comprehension and L2 explicit/implicit knowledge sources. Participants were late adult learners of English as an L2, with a relatively advanced level of English proficiency. They completed tests measuring their WM capacity, explicit knowledge, implicit knowledge, and L2 reading comprehension. Correlation analysis revealed significant relationships between L2 WM capacity and both explicit and implicit L2 knowledge. Exploratory factor analysis showed that explicit knowledge, WM capacity, and L2 reading comprehension loaded on a single factor whereas implicit L2 knowledge formed an independent factor with no relationship to L2 reading. The results suggest that L2 WM is able to manipulate and store both explicit and implicit L2 input through controlled and automatic processes. They also suggest that L2 explicit knowledge, connected with the control processes of the declarative system's lexical/semantic features, and L2 WM, reflecting attentional resource capacity/allocation associated with control processes, play an important role in L2 reading comprehension.

An in-depth exploration of the associations of two aspects of morphological awareness in Chinese—homophone awareness and lexical compounding awareness—to Chinese word reading and vocabulary knowledge was the primary focus of the present study. Among 154 9-year-old Hong Kong Chinese children, both lexical compounding and homophone awareness were significantly associated with word reading (r = .54 for compounding, r = .38 for homophones) and vocabulary knowledge (r = .41 for compounding, r = .53 for homophones). However, with autoregressors additionally statistically controlled, homophone awareness remained uniquely associated with vocabulary but not word reading; lexical compounding was uniquely associated with both word reading and vocabulary. Path analyses best illustrated this pattern. Both morphological awareness constructs are likely bidirectionally associated with word reading and vocabulary knowledge. However, homophone awareness is more centrally associated with vocabulary knowledge because it taps specific, existing morpheme knowledge. In contrast, lexical compounding requires structural understanding of one's language, which seems to be helpful for both learning to read and vocabulary acquisition in Chinese.

It has been argued that children learning a second language (L2) omit agreement inflection because of communication demands. The conclusion of these studies is that L2 children know the morphological and syntactic properties of agreement inflection, but sometimes insert an inflectional default form (i.e., the bare verb) in production. The present study focuses on factors that explain errors with subject–verb agreement in the speech of children learning Dutch as their L2. Analyses of experimentally obtained production data from 4- to 9-year-old L2 children reveal that verb form, sentence position, home language, and L2 proficiency determine accuracy with subject–verb agreement in the L2. Most errors were omissions of inflection, in line with the above hypothesis. However, in more exceptional contexts, the children also substituted verb forms, which is more difficult to reconcile with the claim that L2 children's errors reflect insertion of a default form.

Although pragmatic deficits are well documented in autism, little is known about the extent to which grammatical knowledge in this disorder is deficient, or merely delayed when compared to that of typically developing children functioning at similar linguistic or cognitive levels. This study examines the knowledge of constraints on the interpretation of personal and reflexive pronouns, an aspect of grammar not previously investigated in autism, and known to be subject to differential developmental schedules in unimpaired development. Fourteen children with autism (chronological age = 6–17 years, M = 11) showed some difficulties comprehending personal pronouns, no different from those observed in two groups of younger controls matched on nonverbal IQ or receptive grammar, but in line with the reported pragmatic deficits and general language delay in this population. However, their interpretation of reflexives was significantly worse than that of the control children. This pattern is not evidenced at any stage of typical development, revealing an impaired grammatical knowledge in our sample of children with autism, and is argued not to be due to a general language delay or cognitive deficits.

The Spanish-language MacArthur–Bates Communicative Development Inventories (S-CDIs) are well-established parent report tools for assessing the language development of Spanish-speaking children under 3 years. Here, we introduce the short-form versions of the S-CDIs (SFI and SFII), offered as alternatives to the long forms for screening purposes or in applications requiring a less-demanding instrument. Norming data (SFI: n = 601; SFII: n = 2,534) from diverse populations in Mexico are described. Developmental trends, gender differences, and socioeconomic status effects are reported that parallel those for the long forms. An additional small-scale study (n = 62) demonstrates strong convergence between responses on the long and the short forms. These results provide evidence that the S-CDI SFs have promise for a range of clinical and research applications.
