Miniature language system acquisition by children with different learning proficiencies.

Sixteen children, aged 7:8 to 9:10, learned two miniature languages while playing a communication game. Both languages expressed Action (Agent, Patient) meanings and incorporated a Patient suffix. They differed in word order: VSO (Language I) versus SOV (Language II). Children found the SOV language easier; they also made more suffix errors and fewer word order errors in this language. The results suggest that the perceptual salience of an utterance-final particle may hinder grammatical analysis, at least if capacity limits and perseverative learning strategies intervene.

Spoken and written language relationships in language/learning-impaired and normally achieving school-age children.

Students with language/learning impairment (LLI) and three groups of normally achieving children matched for chronological age, spoken language, and reading abilities wrote and told stories that were analyzed according to a three-dimensional language analysis system. Spoken narratives were linguistically superior to written narratives in many respects. The content of written narratives, however, was organized differently than the content of spoken narratives. Spoken narratives contained more local interconnections than global interconnections; the opposite was true for written narratives. LLI and reading-matched children evidenced speaking-writing relationships that differed from those of the age- and language-matched children in the way language form was organized. Further, LLI children produced more grammatically unacceptable complex T-units in their spoken and written stories than students from any of the three matched groups. The discussion focuses on mechanisms underlying the development of speaking-writing differences and ramifications of spoken-language impairment for spoken and written-language relationships.

Effects of prenatal exposure to cocaine and associated risk factors on language development.

During the past decade there has been a dramatic increase in the number of children born with prenatal exposure to cocaine. However, there is very little hard data concerning the later development of these children. The purpose of this preliminary study was to compare the language development profiles of 5 children prenatally exposed to cocaine and associated risk factors to the language development profiles of a matched non-exposed control group in terms of analyses of the discourse-pragmatic, semantic, and form components of language. The language evaluation was based on the analysis of a 30-minute language sample. The results suggested differences between the two groups as well as differences within the cocaine-exposed group. The major differences between the two groups were in discourse-pragmatics although less marked differences in syntactic development were also found. The results are discussed in relation to the potential contribution of pertinent medical and environmental risk factors. The study suggests that for children with prenatal exposure to cocaine in combination with multiple associated risk factors, language development may be compromised.

Reducing bias in language assessment: processing-dependent measures.

One potential solution to the problem of eliminating bias in language assessment is to identify valid measures that are not affected by subjects' prior knowledge or experience. In this study, 156 randomly selected school-age boys (31% majority; 69% minority) participated in three "processing-dependent" language measures, designed to minimize the contributions of prior knowledge on performance; and one traditional "knowledge-dependent" language test. As expected, minority subjects obtained significantly lower scores than majority participants on the knowledge-dependent test, but the groups did not differ on any of the processing- dependent measures. These results suggest that processing-dependent measures hold considerable promise for distinguishing between children with language disorders, whose poor language performance reflects fundamental psycholinguistic deficits, and children with language differences attributable to differing experiential backgrounds.

Language skills of children and adolescents with Down syndrome: II. Production deficits.

Hypotheses that children and adolescents with Down syndrome show (a) a specific expressive language impairment, (b) a "critical period" for language acquisition, (c) a "simple sentence syntactic ceiling" in production, and (d) deficit in grammatical morphology were investigated cross-sectionally. Conversational and narrative language samples from 47 children and adolescents with Down syndrome (Trisomy 21), aged 5 to 20 years, were compared to those from 47 control children aged 2 to 6 years matched statistically for nonverbal mental age. Children with Down syndrome appear to have a specific language impairment, compared to control children, in number of different words and total words (in the first 50 utterances) and in mean length of utterance (MLU). Total utterance attempts per minute were more frequent in the Down syndrome group. Narrative samples contained more word tokens, more word types, and longer MLU than conversation samples, for both groups. Intelligibility of narratives was significantly poorer for the Down syndrome group than controls. Analyses of narrative language sample by age sub-group showed no evidence of a critical period for language development ending at adolescence, nor of a "syntactic ceiling" at MLUs corresponding to simple sentences for the Down syndrome group. Omissions of word tokens and types were more frequent in the older Down syndrome than the younger control sample, matched on MLU.

Assessments of adolescent language.

I have stressed that language and learning disabilities that are exhibited in the preschool or elementary school years often persist into adolescence but that the characteristics and implications of these disabilities change with the preadolescent and adolescent transitions to metalinguistic maturity. As the student with language disabilities matures and as educational demands increase in complexity and in level of abstractness, the interactions between language and cognition become more apparent. Language disabilities of adolescents are often described in relation to observed deficits in the acquisition of content (semantics), form (morphology and syntax), and use (pragmatics). I have broadened this perspective to consider identification of metalinguistic strengths and/or deficits, deficits in the integration and organization of communication, reasoning and problem solving, and in conceptualization and creativity. Several assessment options were discussed, among them, norm-and criterion- referenced testing, language sample analysis, portfolio assessments of integrated communication, observational checklists and interviews, classroom language probes, and self-assessments. The perspectives taken for assessment have been that no single assessment option can satisfy all assessment objectives and/or constraints. I have also stressed that all tests are subject to measurement error and how to account for this error. Last, but not least, I have shared some of the voices of adolescents which express their perspectives and priorities.

Conversation versus narration in pre-school children with language impairment.

The study focuses on two elicitation methods for language sampling in children with language impairment: conversation and narration. It has been noted in other studies on different clinical groups that language elicited in different speaking contexts varies in aspects such as MLU, fluency and syntactic complexity. The purpose of this study was to compare genre effects on different aspects of language production in a group of pre-school children with language impairment. The results show that there are differences in language production during conversation compared with narration. Intelligibility and fluency were found to be higher in conversation than in narration, whereas MLU in words was higher in narration. The narrative task elicited more phrasal expansions and grammatical morphemes per utterance than the conversation. However, the children used more complex verb forms in conversation than in narration. The results are discussed in relation to recent research.

Follow-up study investigating the benefits of phonological awareness intervention for children with spoken language impairment.

The efficacy of phonological awareness intervention for children at risk for reading disorder has received increasing attention in the literature. This paper reports the follow-up data for participants in the Gillon (2000a) intervention study. The performance of twenty, 5-7-year-old New Zealand children with spoken language impairment, who received phonological awareness intervention, was compared with the progress made by 20 children from a control group and 20 children with typical language development approximately 11 months post-intervention. The children with spoken language impairment all had expressive phonological difficulties and demonstrated delay in early reading development. Treatment effects on strengthening phoneme-grapheme connections in spelling development were also investigated. The results suggested that structured phonological awareness intervention led to sustained growth in phoneme awareness and word-recognition performance. At the follow-up assessment, the majority of the children who received intervention were reading at, or above, the level expected for their age on a measure of word recognition. The phonological awareness intervention also significantly strengthened phoneme-grapheme connections in spelling as evidenced by improved non-word spelling ability. In contrast, the control group of children with spoken language impairment who did not receive phonological awareness intervention showed remarkably little improvement in phoneme awareness over time and the majority remained poor readers. The results highlight the important role speech-language therapists can play in enhancing the early reading and spelling development of children with spoken language impairment.

Development of the Grammar and Phonology Screening (GAPS) test to assess key markers of specific language and literacy difficulties in young children.

BACKGROUND: Despite a large body of evidence regarding reliable indicators of language deficits in young children, there has not been a standardized, quick screen for language impairment. The Grammar and Phonology Screening (GAPS) test was therefore designed as a short, reliable assessment of young children's language abilities. AIMS: GAPS was designed to provide a quick screening test to assess whether pre- and early school entry children have the necessary grammar and pre-reading phonological skills needed for education and social development. This paper reports the theoretical background to the test, the pilot study and reliability, and the standardization. METHODS: This 10-min test comprises 11 test sentences and eight test nonsense words for direct imitation and is designed to highlight significant markers of language impairment and reading difficulties. To standardize the GAPS, 668 children aged 3.4-6.6 were tested across the UK, taking into account population distribution and socio-economic status. The test was carried out by a range of health and education professionals as well as by students and carers using only simple, written instructions. RESULTS: GAPS is effective in detecting a range of children in need of further in-depth assessment or monitoring for language difficulties. The results concur with those from much larger epidemiological studies using lengthy testing procedures. CONCLUSIONS: The GAPS test (1) provides a successful screening tool; (2) is designed to be administered by professionals and non-professionals alike; and (3) facilitates identification of language impairment or at-risk factors of reading impairment in the early educational years. Thus, the test affords a first step in a process of assessment and targeted intervention to enable children to reach their potential.

Together we are heard: effectiveness of daily 'language' groups in a community preschool.

Strong oral language skills are a prerequisite for successful literacy and there is a strong interdependence between oral language acquisition and emergent literacy development. Ramifications of this are that children with language impairments are at great risk for difficulties in learning to read and write, with problems often persisting throughout the school years into adulthood. The Together we are heard program involved improving each child's oral language skills through group sessions facilitated by a speech pathologist on a daily basis at preschool. The aim of the present research was to determine the effectiveness of the program to identify the best way to assist children to develop appropriate language skills. The study showed that the children improved significantly in all four levels of the Preschool Language Assessment Inventory (PLAI). Importantly, the program was effective for both genders and there was no difference in the success of Indigenous children when compared to their European counterparts. There is a strong recommendation for further research and to expand such programs, particularly in areas that target children from impoverished and deprived environmental backgrounds.

Early N400 development and later language acquisition.

Recent developmental research on word processing has shown that mechanisms of lexical priming are already present in 12-month-olds whereas mechanisms of semantic integration indexed by the N400 mature a few months later. In a longitudinal setting we investigated whether the occurrence of an N400 at 19 months is associated with the children's language skills later on. To this end children were retrospectively grouped according to their verbal performance in a language test at 30 months. Children with later age-adequate expressive language skills already displayed an N400 at 19 months. In contrast, children with later poor expressive language skills who have an enhanced risk for the development of specific language impairment (SLI) did not show an early N400. The results imply that children who have deficits in their expressive language at the age of 30 months are already impaired in their semantic development about one year earlier.

Receptive and expressive language skills of children with five years of experience using a cochlear implant.

The language of 7 children who had used a cochlear implant for 5 years was evaluated by means of the Clinical Evaluation of Language Fundamentals-3, the Peabody Picture Vocabulary Test-Revised, and the Expressive Vocabulary Subtest of the Test of Word Knowledge. All subjects demonstrated impaired skills relative to normal-hearing children on 1 or more subtests. Variability in performance occurred between subjects and within subjects across subtests. Strengths in semantic skills were evident compared to weaker syntactic and morphological abilities. The nature of the subjects' language impairments is considered with reference to language delay and specific language impairment. The findings support the need for further evaluation of the rate and course of development of language subskills. Investigation of the influences of information processing, and learning styles and strategies, on children's outcomes is also warranted. These findings have implications for implementation of optimal habilitation and education programs for children with cochlear implants.

Research priorities in language and learning.

The paper reviews recent work in the area of linguistics applied to abnormal language development, specifically in the area of grammar. Particular attention is paid to the notion of linguistic profiling as a procedure for assessment and remediation, using information from normal language development research as a guide. It is suggested that in addition to the potential benefit of the continuing advance in knowledge of normal language acquisition for studies of language disorders, the study of the language of mothers to children could prove of considerable value to the speech and language pathologist.

Toe walking and language development.

Neurodevelopmental markers that are present early in childhood may identify children at risk for later developmental disabilities. This paper attempts to clarify the relationship between one such proposed marker, toe walking, and language development in a general pediatric population. One hundred sixty-three children being seen for well-child visits were included in the study. Information from each child's caretaker was obtained for language development and a history of toe walking; observation of toe walking during the visit was also included. The frequency of toe walking was 24%. Language quotients were calculated and compared for toe walkers (n = 39) and non-toe walkers (n = 127). The mean language quotient for toe walkers tended to be consistently lower than that for non-toe walkers. The specificity of toe walking for low language scores was 85% but had a sensitivity of only 32%. Although an association between toe walking and language delay is supported by the present data, the association does not appear to be clinically significant.

Relationship between parents' report rate of twin language and factors related to linguistic development: older sibling, nonverbal play and preschool attendance.

The definition and nature of twin language has been a focus of recent studies concerned with the phenomenon. There has been a call for a tighter definition and understanding of the meaning of twin language (Thorpe et al., 2001). This article sought to identify social factors associated with the parent report of twin language and thus provide further understanding of the phenomenon. Data from 583 mothers of twins aged 25 to 59 months were analyzed using multiple logistic regression. Factors included in the modeling of parent-report twin language included social experience factors such as presence of siblings, attendance at preschool education and reports of nonverbal play. It was found that twin pairs who didn't have an older sibling, who showed frequent nonverbal play and who didn't attend preschool were more likely to have a twin language. Moreover, in the group not having an older sibling, the influence of whether twins attended preschool or not was strong and the odds ratio was 0.589 (95% confidence intervals 0.360-0.963). The findings suggest that social experience factors are important predictors of the parent reporting of twin language.

Language delays among foster children: implications for policy and practice.

This article highlights the centrality of language in early childhood development and the potential for language delays to negatively affect long-term outcomes in educational and social domains. Given the high rate of language delays in the foster care population, an emphasis should be placed on assessing language skills among children ages 6 and younger entering foster care. The authors describe several existing approaches to assessing language skills and discuss obstacles to the widespread implementation of systematic evaluation among foster children. Finally, the authors discuss the need for research and programming to establish evidence-based practices that encourage the remediation of language delays in this highly vulnerable population.

Speech and language development in a parent-infant total communication program.

In the program described, the use of total communication (TC) did not impede speech development in preschool deaf children. Evidence indicates that sign language facilitated the young hearing-impaired child's acquisition of communicative oral speech. Exposure to sign language combined with speech enhanced the meaningfulness of residual hearing and lipreading. Milestones in sign language acquisition paralleled the milestones of spoken language. Young hearing-impaired TC children appeared to learn and express more language at an earlier age than is typical of orally trained hearing-impaired children. This implies that their cognition may not be as severely inhibited because their language acquisition is less severely delayed. This should have favorable consequences for later educational and social development. The families In the TC program were able to normalize their child-rearing activities and relationships.

The aprosodias. Functional-anatomic organization of the affective components of language in the right hemisphere.

It was recently proposed that the affective components of language, encompassing prosody and emotional gesturing, are a dominant function of the right hemisphere, and that their functional-anatomic organization in the right hemisphere mirrors that of propositional language in the left hemisphere. Ten right-handed patients with focal lesions of the right hemisphere and disorders of affective language are described. Observations were made about each patient's spontaneous prosody, prosodic repetition, prosodic comprehension, and comprehension of emotional gesturing. Using this particular examination strategy, which is derived from the usual bedside approach to aphasic disorders, the organization of affective language in the right hemisphere does mirror the organization of propositional language in the left hemisphere. Furthermore, the disorders of affective language seem to be classifiable in the same manner as the aphasias. Thus, the term "aprosodia," preceded by specific modifiers such as motor, global, transcortical sensory, etc, seems appropriate when classifying the various disorders of affective language that occur following-right-hemisphere damage. The relationships between affect, mood, pathologic laughing and crying, and depression are also discussed.
