Cohesion repairs in the narratives of normal-language and language-disordered school-age children.

The self-initiated repairs produced by 14 normal-language and 14 language-disordered children during a story retelling task are described. When grammatical repairs and repairs to text meaning were analysed, no group differences were found for either repair type. Both groups initiated significantly more repairs to text meaning. When repairs to text meaning were probed for the cohesive aspects of the repair activity, there were no group differences for the frequency or the types of cohesive repairs that were initiated. However, differences were significant for the success of the cohesive repair attempts and for the location of the repairs. Normal-language and language-disordered children appear to share similar strategies for monitoring narrative discourse, but they differ in their abilities to actualize their monitoring attention.

The validity of discrepancy criteria for identifying children with developmental language disorders.

Empirical data from two studies address the clinical validity of discrepancy criteria for identification of children with developmental language disorders (DLD). Study 1 involved 256 preschoolers clinically defined as DLD and meeting inclusionary criteria for normal hearing, intellectual, neurological, and psychiatric status. Application of alternative psychometrically derived discrepancy criteria identified only 40% to 60% of the clinically defined group as language disordered. Study 2 applied nonverbal IQ-language performance discrepancy criteria to 368 eight-year-old, randomly selected control subjects, resulting in over 45% of the controls being identified as DLD. Factors contributing to underidentification in Study 1 and over-identification in Study 2 are discussed, raising questions regarding the validity of discrepancy criteria for identification of DLD children.

Rapid auditory processing in normal and disordered language development.

Four-and-one-half- to eight-and-one-half-year-old children with normal language development, normal adults, and dysphasic children were tested for their ability to perceive binary sequences of nonverbal auditory stimuli. Performance was studied in relation to the rate of presentation of stimulus sequence, as measured by the time interval between stimulus elements. Of the normal children studied, only the eight-and-one-half-year-old group responded as well as the adult group to auditory patterns composed of complex tones presented in rapid succession (8-305 msec intervals). Normal children six-and-one-half years and older were able to respond to these same auditory patterns when they were presented more slowly (947-4026 msec intervals). The overall pattern of performance of the dysphasic children was not similar to that of any age group of children with normal language development. The dysphasics' performance was significantly poorer than that of even the four-and-one-half-year-old normal group on rapidly presented auditory sequences, but not significantly different from normal children their own age or adults on the same patterns which were presented more slowly. The interrelation of normal development of rapid auditory processing and normal language development is discussed.

Children with language disorders: natural history and academic success.

Children with developmental language disorders pose specific and unique problems for educators. This article addresses the continuing academic vulnerability of these children during the school years. We advance the position that their academic vulnerability results from the lifelong need to acquire language, to learn with language, and to apply language knowledge for academic learning and social development. Issues are addressed that relate to persistence of language deficits and learning in school.

Who shall be called language disordered? Some reflections and one perspective.

This paper discusses some issues involved in identifying children who have language problems. The perspective taken is that (a) the goal of identification must be clearly distinguished from other goals of assessment; (b) identification of children with language disorders is better based on language performance than on inferences about the language knowledge that underlies this performance; (c) language performance must be sampled in more than one context, including, for purposes of identification, contexts that stress the language system; (d) the standards of expectations for comparing performance and determining differences must be explicit; (e) standards used to determine differences are better based on the performance of chronological-age peers than on the performance of children with similar mental abilities; and (f) children who do not evidence poor language performance but are considered at risk for language-related problems should be distinguished from children who demonstrate poor language skills.

Language disorders in childhood and adolescence: implications for learning and socialization.

Children and adolescents with language disorders encounter disruption in the fluency of social interaction. Because of the chronic nature of language disabilities, problems in academic achievement and success become the hallmark of the disorders during the school years. Since adolescence represents a time of experimentation and definition of the self, individuals with language disorders are at high risk for the development of fragmented and inappropriate perspectives about themselves. Treatment must address, in a functionally coordinated manner, the acquisition of essential linguistic and basic academic skills, the learning of curriculum content, and the development of appropriate perspectives of the self and the environment.

Diurnal rhythms in performance tests of school children with and without language disorders.

Time-of-day related changes on four tests used by speech therapists and four other performance tests, in addition to oral temperature, were documented in 16 school children (7-9 years of age). Six of them had language disorders and were receiving speech therapy. Children were synchronized with diurnal activity from around 0730 to around 2100 and nocturnal rest. For each child, at each test time point (e.g. 0900, 1100, 1530 and 1930) tests were performed three times, with two different speech therapists, in a random order, with only one session per day. Conventional methods (t-tested mean differences; ANOVA; correlation tests) were used for statistical analyses. Among 29 parameters (items) which were analyzed, only nine exhibited time-of-day related changes, mainly in speed to-perform measures. In most detected rhythms best performance occurred either at 1100 or at 1530 with no difference in subgroups except for the fastest performance of the sentence repetition test. With regard to the daily mean M, controls performed better than children with language disorders for the word (syllabic) repetition test (P less than 0.0004) but this was reversed for both computing and colouring skill tests (P less than 0.04 and less than 0.002). A difference related to sex (but not to language disorders) was observed in the Ms of speed in sign reproduction (P less than 0.0000) and sorting cards (P less than 0.01), with boys being faster than girls. In children, as in adults, time-of-day effects should be considered when the quantification of performance is desired.

[Early management of language disorders].

The audio-language consultations of the Centre d'Audiophonologie of Lyon, France, allow the diagnosis of language delay to be documented in very young children. Based on a five-year clinical study, the authors propose a method of regular follow-up for the child and the parents.

Toe walking. A marker for language disorders in the developmentally disabled.

Toe walking unassociated with an autistic disorder or cerebral palsy generally has been considered a normal infant gait. The incidence of toe walking in various diagnostic subgroups of 799 developmentally disabled children presenting to a tertiary-level multidisciplinary assessment clinic was reviewed to investigate the authors' clinical impression that toe walking may be a marker for language dysfunction. Toe walking was found to be more frequent in those diagnostic subgroups with more severe language disorders. Toe walking also correlated with lower IQ scores (p less than 0.0001). The sensitivities, specificities, predictive validities and odds ratios all supported the hypothesized association between toe walking and language disorders. Further prospective studies of the neurodevelopmental outcome of children with toe walking are needed to determine whether this behavior can identify children at risk for language disorders.

Story grammar ability in children with and without language disorder: story generation, story retelling, and story comprehension.

Twenty language-impaired and unimpaired children ages 9:0 to 11:4 participated in three story tasks. The children generated three original stories, retold two adventure stories, and then answered two sets of comprehension questions after each retelling. Stein and Glenn's (1979) story grammar rules were adapted and used to analyze the narratives. The generated and retold stories produced by the language-disordered children contained fewer complete story episodes, a lower mean number of main and subordinate clauses per complete episode, and a lower frequency of use of story grammar components than those of the control group. The story hierarchies produced by both groups were highly similar, though, in both story generation and story retelling. The groups also did not differ in their understanding of the factual details of the retold stories, but did differ significantly in their comprehension of the relationships linking the critical parts of the stories together. The results are discussed relative to cognitive organizational deficits of language-impaired children.

Brainstem auditory evoked potentials in receptive developmental language disorder.

It has been hypothesized that receptive developmental language disorder (RDLD) may be explained by an auditory processing deficit. The neuroanatomical locus of this deficit is unknown. Brainstem auditory evoked potentials (BAEPs) reflect the functioning of the auditory nerve and auditory brainstem pathways to high-frequency acoustical stimulation in humans and reflect the first stages of auditory processing. These were studied in 12 subjects with RDLD (four females and eight males, ages 12 to 19) and twelve control subjects (three females and nine males, ages 14 to 24). Click intensity and rate of stimulation were varied. The BAEPs for the RDLD group were comparable to the control group as well as to hospital norms across intensity levels and stimulation rates. The evidence obtained suggests that a disorder in the neurophysiological systems underlying the BAEPs and reflecting initial stages of auditory processing is not essential for RDLD.

Nonverbal indicants of comprehension monitoring in language-disordered children.

This study investigated normal and language-disordered (LD) children's patterns of nonverbal behavior in response to messages varying in degree of ambiguity. Each LD child was matched to two normally developing children: one for comprehension level (LM) and the other for chronological age (CM). All children participated in a videotaped ambiguity detection task. Nonverbal behaviors that were produced between the time the message was completed and the examiner's acknowledgment of the response were scored for type of behavior exhibited including eye contact, hand behavior, body movement, and smile. Results demonstrated that all subjects increased their nonverbal behavior (e.g. eye contact) from unambiguous to ambiguous message conditions, suggesting awareness of the differences in these message types at a rudimentary level. Most often nonverbal indication was the only signal of ambiguity detection exhibited by the LD children and their LM peers. Only the CM children concurrently indicated awareness through more direct means (i.e., verbalization and pointing to all possible referents) in a consistent and accurate manner. The finding that LD children did differentiate inadequate from adequate messages in a rudimentary manner suggests that clinicians might promote the intentionality of these preintentional nonverbal behaviors as a possible intervention strategy.

Correlates of language development in language-disordered children.

This study organized a large data archive gathered over 8 years on 718 children with language disorders. Descriptive data categorized by demographic/background, physical/development, social/personality, and language/academic characteristics were analyzed to provide a broad description of this group of children. Sets of descriptor variables in five domains were identified from program records and were used to predict language performance at program entry and relative language improvement over 2-3 years. Age was the strongest predictor for all analyses. In general, the primary research factors in the study (53 variables representing IQ, language history, socioeconomic status, physical/neurological, and social-emotional background) failed to account very well for either language performance at program entry or for relative language gain. In prediction of pretest language performance, IQ and physical factors played the strongest role. The two factors contributing significantly to prediction of relative gain were IQ (although surprisingly weakly) and social-emotional status. Characteristics of those children who progressed most while in the program were identified.

A syntax program designed to present base linguistic structures to language-disordered children.

An intervention strategy for teaching syntax to language-disordered children is described, and the results of its use in a controlled study with 11 children are reported. The therapy program attempts to move the child from single words through a series of successive approximations to use of the construct noun + "is" + verbing + noun, incorporating auditory directions and visual stimuli in the form of cards and boards upon which the cards are sequentially ordered. The results of the experimental group who participated in this therapeutic sequence were compared to those of 11 control subjects and suggested significant gains as measured by the pre- to postprogram performance (t = 2.31, p 0.05). Advantages and limitations of this type of intervention strategy are also discussed.

Conversational aspects of the speech of language-disordered children: revision behaviors.

Revision behaviors in the speech of language-disordered children were investigated. Subjects were 12 children, four at each of Brown's language States I, II, and III. During the taping of a one-hour spontaneous language sample from each child, one of the experimenters pretended 20 times not to understand and asked "What?". The relationship between the child's original utterance and his response to "What?" was analyzed. The results indicated a significantly greater use of revisions than repetitions or no responses at each stage and a pattern of revision behavior that was uniform across stages and qualitatively different from the previously reported patterns of normal children. The results are discussed in terms of the nature of languare disorder and its implications for pragmatic theories of language.
