This study examined mothers' accuracy in predicting the responses their children gave and the scores they achieved on two standardized vocabulary tests. Three groups of 16 mothers and their preschool children (specific language-impaired; age-matched, language-normal; and younger, language-matched, language-normal) completed the Peabody Picture Vocabulary Test-Revised, Expressive One-Word Picture Vocabulary Test-Revised, and Vineland Adaptive Behavior Scales. Mothers overestimated their children's standardized receptive and expressive scores, with the exception that the mothers' estimates of the receptive vocabulary scores for language-impaired children did not differ from the actual test scores. Mothers of age-matched normals were best able to predict the labels their children used to name various pictured items. However, the overall estimates by mothers of language-impaired children were more accurate than those by mothers of language-normal children.

One of the most striking facts about exchange errors in speech is that open class items are exchanged, but closed class items are not. This article argues that a pattern analogous to that in speech errors also appears in intrasentential code-switching. Intrasentential code-switching is the alternating use of two languages in a sentence by bilinguals. Studies of the spontaneous conversation of bilinguals have supported the claim that open class items may be codeswitched, but closed class items may not. This claim was tested by two sentence repetition experiments, one with Japanese/English bilinguals and the other with Spanish/English bilinguals. The results show that the switching of closed class items caused significantly longer response times and more errors than the switching of open class items.

This study examined the conversational patterns of older children with their younger siblings. The sample included 26 nondisabled, 10 hearing impaired, 14 Down syndrome, and 13 developmentally delayed preschool children and their older, nondisabled siblings. Significant differences were found between the nondisabled and the disabled children. The siblings of disabled children appeared to be less conversationally sensitive with their brothers and sisters than the siblings of nondisabled children. Significant differences were also observed between the different types of disabilities. Few significant differences were found in variables believed to be facilitative of language development in the younger child, and those that were found tended not to be in the expected direction.

Two experiments were conducted with the purpose of investigating possible age effects on the abilities of older and younger adults to use contextual information to resolve ambiguous pronouns. In both experiments, subjects were presented with pairs of sentences (a leading sentence followed by a pronominal sentence) and were required to indicate the referent of the ambiguous pronoun. In both experiments, the older adults responded more slowly and were less accurate than the younger adults. However, both groups of subjects were equally influenced by the contextual information available, which was located in the leading sentence to aid in the resolution of the pronouns. Older adults did not demonstrate a specific impairment in the ability to use contextual information to resolve ambiguous pronouns. Nevertheless, agerelated difficulties in resolving pronouns may emerge, possibly as a function of an underspecified discourse model.

The purpose of this study was to investigate word reading abilities in first and third grade Spanish-speaking children who were learning to read in Spanish; the performance of skilled and less skilled readers was compared across measures that assessed phonological recoding ability, knowledge of grapheme-phoneme correspondences, and phonemic awareness. The findings suggest that Spanish-speaking children relied on phonological recoding strategies in the process of becoming readers. First grade, less skilled readers seemed to depend on partial letter-sound knowledge. Furthermore, spelling-sound correspondences appeared to be the main source of information used by first grade, skilled readers and third grade, less skilled readers. The latter seemed to lag behind skilled readers in the use of word-specific information. The phonemic awareness tasks displayed moderate to low correlations with reading ability in the less skilled groups. It is argued that the simple phonological structure of Spanish and its shallow orthography lead to the phonological processing of letter strings during reading acquisition.

This report describes two studies on memory for rote linguistic sequences and sensitivity to rhyme in young children with and without language impairment. In the first study, 10 low income kindergarteners with specific language impairment (SLI) were compared with age- and income-matched classmates on reciting common nursery rhymes, reciting the alphabet, and rote counting. Children with SLI displayed lower performance on most of the rote linguistic sequence tasks, especially on (heir knowledge of Mother Goose nursery rhymes. The second study examined the learning and retention of nursery rhymes in 8 young children with SLI after 6 weeks of classroom instruction. Low-income, 4- and 5-year-old children with SLI and their age- and income-matched classmates were taught five novel Mother Goose rhymes during a large-group classroom activity. Children were tested before and after the intervention on their ability to recite nursery rhymes and to detect rhyme. When compared with their peers, children with SLI had difficulty repeating the nursery rhymes, despite daily classroom exposure. Although the performance of children with SLI on rhyme recitation and detection tasks was poor, their relative performance was better on a cloze task based on the set of nursery rhymes. The results of this study suggest that children with SLI have difficulty storing and/or retrieving lines of memorized text. Traditional informal techniques for teaching rote linguistic sequences may need to be modified to give children with SLI more opportunities to practice rote sequences.
