The use of complex syntax was investigated in narrative language samples of older children and adolescents with Down syndrome (n = 24) and a group of typically developing children matched on mean length of utterance. Both groups used conjoined and subordinate sentence forms and did not differ significantly in either the proportion of utterances containing complex sentences or in the variety of complex sentence types used. The analysis of developmental patterns suggested a similar order of acquisition across groups. The findings indicate that syntactic development in individuals with Down syndrome continues into late adolescence and is not limited to simple syntax. This study does not support earlier findings of a critical period effect in syntactic development in Down syndrome based on age or syntactic complexity.

This article presents an analysis of 500 submorphemic slips of the typewriter key that escaped the notice of authors and other proofreaders and thereby made their way into the published records of scientific research. Despite this high selectivity, the corpus is not found to differ in major ways from other collections of keying slips. The main characteristics of this error type include a predominance of within-word slips, an elevated rate of noncontextual slips, a heightened incidence of omissions (in particular, masking errors), a high number of adjacent switches, and an uncommonness of these slips in word edges. In all these respects, slips of the key resemble slips of the pen, although not slips of the tongue. It is argued that speech errors are shaped by a fully deployed structural representation, whereas key slips arise under the influence of a weak structural representation. By implication, speaking is characterized by a hierarchical strategy of activation while typewriting is subject to the so-called staircase strategy of serialization in which activation is a function of linear distance. These disparate strategies may be understood as a response of the processing system to disparate requirements, such as varying speed of execution.

The study of African American English (AAE) has been historically focused on the dialectal variations of adolescent and adult speakers. More recent investigations of dialect used by very young AAE speakers were undertaken with the goal of describing the language produced by early elementary and preschool-aged children. One important outcome of these studies is increased attention to the importance of considering the impact of developmental influences in our characterizations of dialect use. In this study we explore the differences between primary caregivers and their young children in dialect use across generations by directly examining the dialectal variations apparent during play interactions between primary caregivers and their young children. We conclude that there is indeed evidence in these interactions of differences between the child and caregiver in the structure and use of individual AAE features. Another conclusion is that there are many similarities in the distribution of AAE between these older and younger interactants, highlighting not only their kinship ties but also their membership in the same linguistic community.

Lexical stress patterns appear to be important in word recognition processes in normal individuals. The present investigation employed a lexical decision task to assess whether left (LHD) and right hemisphere damaged (RHD) patients are similarly sensitive to stress patterns in lexical access. The results confirmed that individuals without brain damage are influenced by stress patterns, as indicated by increased lexical decision latencies to incorrectly stressed word and nonword stimuli. The data for the LHD patients revealed an effect of stress for real word targets only, whereas the reaction time data for the RHD patients as a group showed no significant influence of stress pattern. However, there was a great deal of individual variability in performance. The latency and error rate findings suggest that LHD patients and non-brain-damaged individuals are both sensitive to lexical stress in word recognition, but the LHD patients are more likely to treat incorrectly stressed items as nonwords. The results are discussed in relation to theories of the hemispheric lateralization of prosodic processing and the role of lexical stress in word recognition.

Children with specific language impairment (SLI) have distinctive impairments in the comprehension of sentences that involve long-distance syntactic relationships. This has been interpreted as evidence for impairment in an innate grammatical module. An alternative theory attributes such difficulties to lower level problems with speech perception or deficits in phonological working memory. These theoretical accounts were contrasted using comprehension data from three subgroups: 20 children with SLI, 19 children with mild–moderate hearing loss, and normally developing children matched on age and/or language level. There were close similarities between the hearing-impaired and SLI groups on a measure of phoneme perception. Children with SLI did poorly on tests assessing knowledge of Binding principles and in assigning thematic roles in passive sentences whereas hearing-impaired children performed close to control levels, indicating that poor speech perception cannot account for this pattern of deficit. However, the pattern of errors on syntactic tasks and the relatively weak correlation between different indicators of syntactic deficit seemed incompatible with a modular hypothesis. We propose that limited processing capacity is the principal determinant of deficient syntactic comprehension in SLI.

Letter names bridge the gap between oral and written language among English speaking children. This study examined whether letter names have a similar function in Hebrew. Despite their common historical source, Hebrew letter names differ from English: they are longer and not as regular phonologically. However, they follow the acrophonic principle, unlike many English letter names. Israeli kindergartners, whose mother tongue was Hebrew, were asked to orally provide initial or final letters of spoken words, to spell words in writing, and to select one written word out of two as standing for an oral word. First graders were tested on orally providing the initial letter and spelling. Children were found to rely on letter names in performing all these tasks. They succeeded more in providing the initial letter or in spelling it if the word started with a letter-name sequence, like kaftor (button), which is spelled with k (Kaf). They succeeded more in selecting the correct word between two if the words started with a letter-name sequence. In grade 1 the effects decreased and became limited particularly to phonemes spelled with homophonic letters. Partial letter names (impossible in English) affected performance but to a lesser extent than entire names. Reliance on letter names both facilitated and impaired performance but in different ways than in English. The educational implications are discussed.

The beauty of edited volumes is their potential to achieve synergism in bringing together diverse work on a significant topic – not just to create a coherent collection of research. Literacy in African American communities succeeds on all fronts. In presenting a broad view of literacy-related practices, the volume evokes a variable African American community that is invisible (or at least hazy) in many schools. Without deep knowledge of the linguistic, cultural, historical, and political contexts for literacy in the community, the schools and university programs that prepare professionals cannot hope to overcome the deficit perspective of cultural and linguistic differences that still drives assessment and instruction to a large degree.

Since the late 1980s, the Child Language Data Exchange System (CHILDES) has defined the state of the art of collection, analysis, archiving, and data sharing of transcriptions of children's language. Starting from scratch in 1987, Brian MacWhinney, along with many other leaders in child language, developed highly useful tools for the computerization of transcripts and their analysis. I have used the transcription conventions and analysis programs since 1989 and have seen the system evolve from a simple DOS-based program to one that handles much broader and more complex analyses within more user-friendly Windows and Macintosh platforms. This latest (third) edition of the manual that accompanies the CHILDES system reflects a more stable version of the Conventions for Human Analysis of Transcripts (CHAT) and Child Language Analysis (CLAN) programs than prior editions, which felt like works in progress. This version is written as a finished product with procedures and programs that have settled down into stable patterns of operation.

Laurence Leonard is one of the most prolific and well-respected researchers in the area of specific language impairment (SLI) in children, and he is well qualified to write a book surveying the topic. SLI is a disorder of unknown origin, which appears to have a genetic component, causing delays and disorders of language development in children of normal nonverbal intelligence with no significant medical, emotional, or sensory deficits. The primary purpose of this book is to provide a comprehensive review of research in the field of SLI, and Leonard has the minute knowledge necessary to succeed at the task. The coverage in the book reaches back to the earliest nineteenth-century descriptions of children who fit the profile and then moves forward quickly to the massive literature that has accumulated on the topic in the last 20 years. Following the introductory historical and definitional section, Leonard goes on to describe the nature of the linguistic impairment in SLI, including important cross-linguistic accounts and nonlinguistic cognitive issues. The book also covers hypotheses of causation, in a “nature versus nurture” section, and clinical issues of assessment and intervention. Part V, on theory, may be of most interest to psycholinguists who are not language disorders specialists. Overall, there is no doubt that this book is both an excellent introduction for those unfamiliar with SLI and a welcome overview and resource for experts. Leonard's knowledge is encyclopedic, his presentation erudite, and his grasp of detail unfailingly impressive.
