Few studies on augmentative and alternative communication (AAC) systems have addressed the potential for such systems to impact word utterances in children with autism spectrum disorders (ASD). The Picture Exchange Communication System (PECS) is an AAC system designed specifically to minimize difficulties with communication skills experienced by…

The current study attempts to differentiate effects of phonotactic probability (i.e. the likelihood of occurrence of a sound sequence), neighbourhood density (i.e. the number of phonologically similar words), word frequency, and word length on expressive vocabulary development by young children. Naturalistic conversational samples for three…

We hypothesize that the conceptual relation between a verb and its direct object can make a sentence easier ("the cat is eating some food") or harder ("the cat is eating a sock") to parse and understand. If children's limited performance systems contribute to the ungrammatical brevity of their speech, they should perform better on sentences that…

The present research investigated whether children's referential choices for verb arguments are motivated by pragmatic features of discourse referents across different developmental stages, not only for children learning null argument languages but also for those learning overt argument languages. In Study 1, the form (null, pronominal, or…

Behavioral data establish a dramatic change in infants' phonetic perception between 6 and 12 months of age. Foreign-language phonetic discrimination significantly declines with increasing age. Using a longitudinal design, we examined the electrophysiological responses of 7- and 11-month-old American infants to native and non-native consonant…

Speech language pathologists have recently begun to provide community-based education programs to help prevent speech and language problems. These training opportunities can be particularly useful to programs that serve low income families. The authors describe Tips About Talk, a general education and prevention program designed to help caregivers…

This study compared multiple characteristics of girls' and boys' vocabulary in 6 different linguistic communities--1 urban and 1 rural setting in each of 3 countries. Two hundred fifty-two mothers in Argentina, Italy, and the United States completed vocabulary checklists for their 20-month-old children. Individual variability was substantial…

Purpose: This study examined whether child speakers of Southern African American English (SAAE) and Southern White English (SWE) who were also perceived by some listeners to present a Cajun/Creole English (CE) influence within their dialects produced elevated rates of 6 phonological and 5 morphological patterns of vernacular relative to other…

Purpose: Vocalization development has not been studied thoroughly in infants with early-identified hearing loss who receive hearing aids in the 1st year of life. This study sought to evaluate the relationship between auditory sensitivity and prelinguistic vocalization patterns in infants during the babbling stage. Method: Spontaneous…

This article presents the Let's Talk project as a different approach to oral language development. This approach was based on observations of classrooms in the Netherlands where children talked at large tables while playing with miniature figures representing people and objects they were familiar with in their daily lives. It was also influenced…

This book introduces beginning students of linguistics at all levels and general readers to the study of language, providing an overview of key topics and an explanation of basic terms and ideas. The book is also designed to encourage the reader to think about the way language works and reconsider some popular misconceptions about language and…

An overview of current theories of reading and the acquisition of literacy skills by children is presented. A research framework in which reading can be described in terms of the processes employed in other language uses is introduced and used to explain the failure of some children to learn to read. An ongoing research program is described that…

This study examined how modes of organizing conversation determine the type of knowledge conveyed to preschool and kindergarten children. Approximately 150 audiotaped conversations from 23 classes of students of different age levels from 2 to 6 years were analyzed. Children's spontaneous speaking turns or answers to teachers' questions were…

Examples of writers' workshops and ways to implement them for children's second-language learning are described in this handbook for teachers. Writers' workshops are important structured classroom events that provide children with opportunities to demonstrate their facility as writers. The theory behind writers' workshops is that children…

The Highland (Indiana) public schools developed a writing program for elementary school students based on the premise that children learn to use language by actively generating language. The program features language production as the principal student activity in the English class and uses the students' own written work and oral expression as the…
