[Use and comprehension of prepositions by children with Specific Language Impairment].

BACKGROUND: The ability of children with Specific Language Impairment (SLI) to use and comprehend closed-class words. AIM: Acknowledging the increasing search for the characterization of linguistic performance of this population in different languages, as well as the findings of international literature that stress the difficulty of these children in using closed-class grammatical morphemes, the aim of this study was to analyze the performance of children with SLI in tests of production and comprehension of prepositions. The purpose of this research was also to compare the performance of these children to that of their typical language developing peers, in terms of the overall index of correct answers and the most frequent types of errors in both groups. METHOD: An objective test was developed in order to analyze production and comprehension of four types of prepositions that are used to establish the following semantic relations: with (company relation); by (way relation); in, on or at (place/position relations); and to (destination relation). This test was carried out with 19 SLI children and 29 typically developing children (CG--control group), one year younger than the research group. RESULTS: SLI children presented the same pattern of results, although delayed, of children in the CG in the comprehension test. In the task involving production, however, the performance of SLI children was quantitatively and qualitatively inferior to their typical developing controls. This performance was mainly characterized by the omission of prepositions. CONCLUSION: The findings corroborate the view that grammatical words constitute a challenge for SLI children, since they presented many errors that suggest difficulties in the domain of prepositions. The results also emphasized, for the SLI group, deficits in the expressive language.

[Analyses of answers presented by children with and without specific language impairment].

BACKGROUND: children start to differentiate questions from non-questions and also start to adjust their answers at the age of two. This participation in verbal exchanges requires basic conversational abilities such as the competence to initiate interact and reply appropriately, and to maintain the interaction. AIM: to analyze and correlate the pragmatic aspects of language, related to the type of answers, during an adult/child interaction in children with normal language development and in those diagnosed with Specific Language Impairment (SLI). METHOD: 16 children with SLI (GP) and ages between three and six years, and 60 children with normal language development (GC) and ages between three to five years - 20 for each age group, 10 of each gender. Data gathering occurred in two different days, with the adult/child interaction being facilitated by toys. Data (speech of child and adult) were transcribed and analyzed, obtaining a Reliability Index of 93.75%, and later were submitted to statistical analyses. RESULTS: answers were classified in categories and grouped according to the following: Adequate Answers (RA) and Inadequate Answers (RI), always in accordance to the established communicative context. GC presented a significantly higher average of RA when compared to GP, and GP presented a significantly higher average of RI when compared to GC. GC presented a decrease in the use of RI at the increase of age. GP maintained the use of RI at the increase of age, including the age group of six. CONCLUSION: it was observed that the increase in age emphasized differences between GP and GC. GP presented a less effective communication maintaining unintelligible speech, whereas GC presented more elaborate communication abilities. More studies with older children are necessary for the better understanding of the observed trends.

In vivo language intervention: unanticipated general effects.

After observing the lack of generalization of language trained in highly structured training sessions using established behavior modification techniques, "incidental teaching" procedures were developed to change the use of specified language behaviors in the natural environment. This paper reports an analysis of the general changes in the language, other than that specifically targeted by the incidental teaching procedures, used by disadvantaged preschool children. The daily language samples of disadvantaged children involved in a previously reported experiment to increase compound sentence usage were reexamined and compared to comparable records of other disadvantaged children and of middle-class children of college parents in order to assess possible general effects of the intervention program. Whereas the language that both groups of comparison children used changed little across the preschool year, the amount of talking by the children in the experimental program increased markedly. Their use of more elaborate vocabulary and more elaborate sentences also increased in direct proportion to the increases in overall language use, such that both language use and language elaboration in the experimental group of children changed from a pattern simlar to the comparison group of disadvantaged children to a pattern similar to the comparison group of middleclass children. It is argued that some general features of the incidental teaching procedure--differentially attending to child overtures and responding relative to the child's selected topic (reinforcer)--contributed to the increase in overall language use beyond the specific language behavior targeted, and that this increase in the probability of children's talking itself resulted in the substantial increases in elaboration seen in the children's spontaneous language. Because, at least in children with fairly well-developed language repertoires, language use is contextually controlled, talking more involves talking in more varied and complex contexts, which inevitably produces the use of more elaborate language.

Development of spontaneous manding in language deficient children.

Six institutionalized children, aged 7-11, with little or no spontaneous vocal manding, were trained to request food items under appropriate natural conditions when snacks were presented. "I want a" was appropriate when an adult presented food in the playroom. "Out" was appropriate when the items were displayed in the hallway, across a half-door barrier from the child. A sequence of steps was trained, through increasingly naturalistic setting and cuing conditions. The two mands were trained in sequence, not concurrently. To encourage "spontaneous" productions, no vocal cuing was provided by the adult. After criterion performance in each step, several probe sessions were conducted for various cuing conditions, adults, and settings. Probes after imitation training showed no spontaneous manding. Thus, failure of manding was not due to production difficulties. In probes after training for "approximately" natural cues, most children showed little transfer to the natural cues. This implies that training for the specific appropriate cues may often be required. However, good transfer generally occurred across persons, and from training room to playroom. Probes also showed that most children did not use one of the trained mands in the stimulus conditions that were appropriate for the other mand. Thus, adding a second mand did not generally disrupt use of the first. However, significant disruption occurred for two children. Finally, at the end of training, extinction training was given for one mand in one setting. Performance of the other mand was little affected. In sum, the appropriate form of a mand depends on specific stimulus and setting characteristics, and these characteristics must be considered in training.

Teachers' generalized use of delay as a stimulus control procedure to increase language use in handicapped children.

In Experiment 1, classroom teachers were taught to delay their offers of help in naturally occurring situations, and thereby to provide additional opportunities for language use by six moderately retarded language-delayed children. The teachers introduced this delay technique in a multiple-baseline design across the six children. As delays were used, child verbal initiations increased. Follow-up assessment showed that teachers were maintaining greater than baseline levels of the delay technique after 10 weeks. Experiment 2 replicated the findings of Experiment 1, and included a more thorough maintenance assessment, while focusing on teachers' generalization of the delay technique. Teachers were found to generalize their use of delay to 56% of their monitored untaught opportunities. The two experiments show that (a) the delay technique is quick to teach and simple to implement, (b) delays do provide opportunities for children to initiate, (c) teachers can generalize their use of delay to novel self-selected situations, and (d) teachers can maintain their use of delays over time.

Evaluating a supervision program for developing and maintaining therapeutic staff-resident interactions during institutional care routines.

This study evaluated a program to teach and maintain language training interactions between institutional staff and profoundly handicapped children during a routine care task. Following baseline observations of bath sessions, staff were sequentially taught in multiple baseline fashion to vocalize more during the bath, praise child vocalizations, imitate sounds, and provide sound prompts. Procedures included a brief in-service meeting followed by a series of supervisory prompts and feedback. Results indicated that staff acquired the interaction skills in the bath sessions and that the skills generalized to another direct care task, dressing. The number of days on which components of supervision were implemented decreased from 47% of all days during the experimental conditions to 19% of the days during a 19-week maintenance period with no decrease in staff behavior. The interactions were shown not to interfere with the quality of the direct care task nor to increase the amount of time necessary to complete it. Also, some increases were noted for child vocalization frequencies. The advantages of providing therapeutic interactions during care routines are discussed along with the need for staff management techniques with long-term maintenance value.

A methodology for assessing the functions of emerging speech in children with developmental disabilities.

An approach based on Skinner's (1957) theory of verbal behavior has been developed to understand and teach elementary communication skills to children with autism and developmental disabilities (Sundberg & Partington, 1998). However, few studies have directly examined the characteristics of emerging language in children with developmental disabilities. The purpose of this study was to develop and evaluate an assessment for identifying the elementary functions of vocal speech in children. Participants were 4 children with developmental disabilities, aged 6 years to 12 years, who exhibited at least one distinguishable vocal response (word or phrase) frequently in the natural environment. The assessment focused on three verbal operants delineated by Skinner (mand, tact, and intraverbal). One or more functions were identified for at least one vocal response of each child. Results suggested that this assessment would be useful for (a) evaluating Skinner's theory, (b) guiding decisions about language training for individual children, and (c) studying the nature of expressive language development in children with developmental disabilities.

Relationship of reinforcement by student clinicians and peers to accuracy of imitated grammatical constructions during language training.

Percentages of correctly imitated grammatical constructions were examined within a framework of reinforcement theory. Four small treatment groups, each of 4 language-delayed children, were repeatedly observed interacting with different student-clinicians. The Therapy Reinforcement Schedule was used to obtain frequency counts of verbal and non-verbal reinforcements so that within each language group the students could be objectively divided into those who frequently and infrequently were reinforcing, and the children into those for whom peer-reinforcement was high or low. The resulting 4 groups were compared for proportions of accurately imitated constructions with a repeated-measures analysis of variance design (student-clinicians' reinforcement x peers' reinforcement x trials). Correctly scored imitations increased significantly over trials. In addition, children interacting with frequently reinforcing students received higher imitation scores than those with infrequently rewarding ones. Significant main effects of reinforcement by the peer group were not observed, although a reliable interaction of student-clinicians' reinforcement x peers' reinforcement was present. Regression analyses indicated the importance of certain types of reinforcements in predicting accuracy of imitation.

Mode-relations in language learning by language-deficient retarded subjects.

The relationship between language comprehension and production was examined with two severely language-deficient retarded subjects who were taught the plural form /z/. Comprehension and production were trained concurrently with different words in each mode until correct plural use occurred in the untrained mode for each word. Subsequent training of reversed plural use in comprehension for one subject and production for the other failed to result in reversed plural use in the untrained modes for those words. This mode-independence contrasted with interdependence displayed by normal children in earlier study using similar procedures. The results are discussed in relation to the normal developmental process and the possible deviation from it.

Decelerated synthesized speech as a means of shaping speed of auditory processing of children with delayed language.

This study investigated whether the rate at which children with delayed language process auditory stimuli can be increased through a process of shaping with synthesized speech stimuli. Results indicate that stimuli with slowed down critical formant cues were easier for these 24 children with delayed language to discriminate and that training with stimuli of extended duration did generalize to stimuli of normal durations. Implications of these findings and usefulness of this methodology are discussed.

Facing a communicative obstacle: pragmatics of language-impaired children.

The ability of school-age, language-impaired children to respond when faced with a communicative obstacle was investigated. 18 language-impaired children were compared to 2 control groups, age-mates and language-mates. Language-impaired differed from both controls. They communicated more effectively than younger language-mates and less effectively than age-mates.

Comparison of the Token Test of Language Development and the Wechsler Intelligence Scale for Children--Revised.

Correlations were calculated between the Token Test of Language Development (Token) and scores of the Wechsler Intelligence Scale for Children--Revised (WISC-R) based on responses from 38 Caucasian children (23 boys and 15 girls) of a semi-rural Northeastern Ohio school district. The relatively low Pearson correlations (.25 to .47) between the standard scores in the Token test and WISC-R IQs are discussed in relation to ability and achievement.

Referential communication abilities of learning-disabled, language-learning-disabled, and normal school-age children.

Past research in referential communication has indicated normally developing children show developmental progression in ability to communicate a specific referent to a listener. In one paradigm subjects were given lists of word-pairs in which one member of each pair was designated as the referent. It was shown that communicating about referents found in word-pairs associated in some way was more difficult than communicating about referents in dissimilar word-pairs. The present study extended this methodology to learning-disabled children. Learning-disabled, language-learning-disabled, and normally achieving children were asked to communicate about 30 pictured referents on three different tasks. On Tasks 1 and 2 each subject was asked to give a clue for the referent that would distinguish it from the other picture. Stimuli for Task 1 were 30 pairs of pictures that were related in some way and the stimuli for Task 2 were 30 pairs of unrelated pictures. Task 3 required the subjects to evaluate the adequacy of the examiner's clues for Task 1 stimuli. The disabled subjects were matched to the normally achieving subjects on the basis of receptive vocabulary age. Few differences were noted among the groups' performances on these referential communication tasks. Implications include the importance of vocabulary and concept development to referential communication.

A pilot study on the effect of training parents of language-delayed children in pragmatic interaction strategies.

This pilot study investigated pragmatic language training on parental expansion of interactive strategies, and a corresponding decrease in using questions and imperatives in parental communication with their language-delayed preschool children. Seven parent-child dyads participated, with the parents receiving training in the acquisition of six pragmatic categories, including reference, model, imitation, description, parallel talk, and expansion. Training results showed a significant increase in the parents' use of parallel talk and a decrease in their use of questions. Apparently in many instances parallel talk may incorporate the strategies of referencing, modeling, imitation, description, and expansion. Findings are discussed in terms of parallel talk functioning as a facilitator for language-delayed children.

Selecting language-impaired children for research studies: insights from the San Diego Longitudinal Study.

The need for a standardized approach to the selection of research subjects for studies on language impairment has long been an area of controversy in the literature. The data obtained from the selection of language-impaired and control subjects for the San Diego Longitudinal Study allows one to evaluate the effects a two-stage subject-selection procedure has on the characteristics of the language-impaired and normal subjects selected for research studies. Specifically, what effect do quantitative measures, as compared to clinical judgements and referrals, have on the characteristics of subjects selected for research studies? Explicit and detailed oral and written descriptions of subjects sought for both a language-impaired group and a control group were given to teachers and clinicians. However, only 39 of the first 100 children referred as language-impaired and 29 of the first 60 referred as normal controls were found on standardized testing to meet the study criteria and to be matched on important variables, such as IQ and socioeconomic status. These results demonstrate the importance of establishing quantitative inclusionary as well as exclusionary criteria for selecting and matching subjects in clinical research studies.

Predicting preschool speech/language referral-status with the Lollipop Test and the Cognitive-Language Profile of the Early Screening Profiles.

603 preschoolers who attended early childhood screenings were administered the Lollipop Test, the Cognitive Language Profile of the Early Screening Profiles, and the Fluharty Preschool Speech and Language Screening Test. Scores from the Lollipop and the Cognitive-Language Profile significantly predicted speech/language referral-status based on Fluharty scores and clinical judgment.

Language abilities of neurologically normal and suspect preterm children now in preschool.

Multiple aspects of speech and language performance of 29 four- to five-year-old preterm children (10 neurologically suspect) were assessed. Data were collected using a variety of measures including standardized tests and analysis of language samples. Each child's performance was compared with reference data on the various outcomes which yielded an over-all pass score and individual profiles of performance. Neurologically normal children had significantly higher passing scores than suspect children but appeared to be at risk for mild language delays, particularly in morphosyntactic development. Neurologically suspect children appeared to be at risk for moderate and more generalized language delays, including morphosyntactic and phonological development.
