During an eight-month treatment regimen utilizing simultaneous sign/speech input, all of the words of a young girl with Down's Syndrome were recorded. Analyses revealed that most of the words she initially signed were later spontaneously spoken and that most of her signed productions evolved into spontaneous spoken productions. (Author/JDD)

Reports a study of two- and three-year-olds' acquisition of complex sentences with perception and epistemic verbs that took a second verb in their complements. Complement types, complementizer connectives, and the discourse contexts in which complementation occurred were specific to individual matrix verbs. (Author/CB)

Analysis of mothers' pragmatic language use and children's language levels during free play sessions suggested that a mother-driven, direct influence model may be inappropriate for many mother speech-child language development relationships and points to the feasibility of child- and mother-driven explanatory models for indirect relationships.…

Re-analysis of data regarding children's acquisition of tense and aspect indicated that children learning Polish were influenced by aspect in acquiring verb tense in the same way as children were influenced in learning other languages. Children beginning to learn verb inflections found aspectual contour particularly compelling in leading them to…

Shares the experiences of telling stories to three-year-old Tim, who began to take over parts of the stories to tell himself. Suggests that, by making storytelling an interactive event, adults can help children feel comfortable enough in storytelling to be confident of their own emergent narrative ability. (MG)

The literature on the critical role of parents in the education of children with severe learning difficulties is discussed in the context of playgroups and nursery schools, language training, home-school contacts, teaching by parents, and school leaving. (DB)

Explores the concept of markedness in two different linguistically based approaches to universals in second language acquisition. While typologists define markedness implicationally, current theories of language learnability define markedness in terms of the Subset Principle. (21 references) (Author/CB)

Presents the results of an analysis of the acquisition of fricatives in 5 English children between the ages of 24 and 49 months. After giving an overview of the area of articulatory phonetics and citing previous research, data collection, scoring problems, and error analysis are discussed. (CFM)

Six autistic children, age 3-6, and 6 children with Down syndrome were followed over a period of 12-26 months. Autistic children followed the same general developmental path as the Down syndrome children in the acquisition of grammatical and lexical aspects of language. (Author/JDD)

Sensorimotor functioning in 10 autistic children, age 3-7, was assessed on object permanence, means-end, causality, vocal and gestural imitation, the construction of objects in space, and schemes for relating objects. The number and diversity of pragmatic functions in the children's communication were also analyzed and related to sensorimotor…

Explores how children learn the range of aspect inflection to which a verb is amenable. Analyses focus on the children's mastery of Aktionsart specific intersentential patterns. Three conclusions are given based on the study's results. (21 references) (GLR)

Examination of parental responses to their young children's (N=3) inflectional over-regularizations and wh-question auxiliary-verb omission errors suggested that two of the children's parents followed ill-formed utterances with expansions and clarification questions. Such corrective responses dropped out of children's input as they continued to…

Analysis of speech samples from four-year-old monozygotic and dizygotic twins revealed that the monozygotic twins were significantly more likely to misproduce the same sound on an articulation test than were dizygotic twins. The dizygotic twins were no more likely to share errors than were children who were both genetically and environmentally…

Attempts to provide a plausible theory of music's evolutionary development. Speculates that music may have provided survival benefits by helping establish mother/infant bonds, by aiding in the acquisition of knowledge, by providing a unique way of knowing, and by playing important roles in social organization.

A study of two- to six-year-olds' spontaneous uses of "from" to mark oblique agents showed that, while the two-year-olds produced "from" for agents and "with" for instruments in imitation, older subjects shifted to "by" for agents and kept "from" to mark locative sources. (Author/CB)
