This study re-examined the language and social skills of four females with language impairment who were initially studied eight years ago (Brinton, Fujiki, Montague, & Hanton, 2000; Fujiki, Brinton, Isaacson, & Summers, 2001). Language measures included the Clinical Evaluation of Language Fundamentals-Fourth Edition (Semel, Wiig, & Secord, 2003) and a thirty minute language sample. Social measures included the UCLA Loneliness Scale-Version 3 (Russell, 1996), parent, teacher and student forms of the Social Skills Rating System (Gresham & Elliott, 1990), and an interview with each participant's teacher or speech-language pathologist. Results of the current assessment were compared to results from the original assessment. In terms of social ability, the two girls who were classified as having the best social skills initially, Jean and Kristine, still appeared to be the most successful in the current study. Despite their social strengths, Jean's teacher indicated that she was socially immature and had difficulty reading the social cues of teachers and peers. Kristine reported that she prefers isolation. Her teacher reported that Kristine may be at risk for self-harm. Amy was still enrolled in resource and speech-language services. Though she had found acceptance in a cultural peer group, her communication style often appeared rude and disrespectful to adults. Marie was dismissed from speech-language intervention, but was still enrolled in resource and received extra academic support from Sylvan Learning Center to be moderately successful. Socially, she demonstrated a high level of problem behaviors and mood swings. According to the UCLA Loneliness Scale, she experienced the most loneliness and isolation of the four subjects. Similar to what has been observed in group studies of children with language impairment, the results from this study found social deficits in these individuals persisted into young-adulthood.

This study examined the electrophysiological activity of two children with Specific Language Impairment (SLI) and two aged-matched peers while listening to syntactically correct sentences versus syntactically incorrect sentences. The study specifically analyzed the N400 and P600 components. The N400 component is a negative wave occurring approximately 400 ms post-stimulus and is elicited by semantically incorrect stimuli. The P600 component is a positivity that occurs approximately 600 ms post-stimulus and reflects processing of syntactically incorrect stimuli. The participants in the study included a 7-year-old child and a 9-year-old child with SLI and two age-matched peers with typically developing language. Each participant listened to a series of syntactically correct and incorrect stimuli. The results of this study indicate that children with SLI present with an N400 while listening to both syntactically correct and incorrect stimuli. This suggests that these participants have greater lexical and semantic processing demands while listening to sentence stimuli. The study also suggests that 7-year-olds have greater syntactic processing demands as seen by the presence of the P600 in both the correct and incorrect conditions. This was likely due to the complexity of the sentence stimuli which included irregular past tense and irregular plural forms. Further research is still needed in order to better understand the role of the N400 and P600 in children with SLI, which will provide useful information regarding the neurological basis for language impairments.

Recently researchers have identified a group of children with language impairment (LI) whose IQ scores are below the typical IQ cutoff of 85 for specific language impairment (SLI) but above the IQ cutoff of 70 for intellectual disability (Weismer et al., 2000). This group is referred to as having nonspecific language impairment (NLI). Eleven children with NLI, eleven same-age peers with SLI, and eleven same-age typical peers were compared on withdrawn and sociable behaviors demonstrated in the classroom setting using the Teacher Behavior Rating Scale (Hart & Robinson, 1996). Three subtypes of withdrawal (solitary-active, solitary-passive, reticent) and two subtypes of sociable behavior (impulse control/likability and prosocial) were examined. The children were compared on the severity of their ratings as well as the pattern of item responses for each behavioral subtype. Teachers rated the group with NLI significantly more poorly than the typical group on the reticence, impulse control/likability, and prosocial subtypes. Teachers rated the group with SLI significantly more poorly than the typical group on the impulse control/likability subtype. Participants were added to the typical group and the group with SLI to increase statistical power. With additional participants, the children with SLI were also rated significantly more poorly than the typical children on the reticence, likability, and prosocial subtypes. The group with NLI was consistently rated more poorly than the group with SLI except on the solitary-active subtype. However, there were no significant differences between the groups with LI, even with additional participants. The pattern of item responses was similar between the groups with NLI and SLI on all behavioral subtypes. In addition, the pattern of item responses for the groups with LI also matched the pattern of the typical group on the solitary-active withdrawal, impulse control/likability, and prosocial subtypes. These data indicate that the differences between the groups with NLI and SLI may be quantitative but not qualitative.

The purpose of this study was to determine whether children with specific language impairment (SLI) are more or less variable than children with typically developing language. In addition, the within child variability for children with SLI was analyzed to consider how heterogeneity influenced identification of areas of linguistic strengths and weaknesses in this population. Fifty seven children with SLI, 7:0–11:0, and fifty seven of their peers with typically developing language were assessed using five subtests and a composite language score from the Comprehensive Assessment of Spoken Language (CASL) (Carrow-Woolfolk, 1999). The children with typically developing language were significantly more variable as a group than the children with SLI. The heterogeneity of the children with SLI did not allow for the creation of subgroups based on language strengths and weaknesses.

The correct use of morphological suffixes in obligatory contexts reflects linguistic knowledge and competence of speakers. Grammatical knowledge is acquired during a child’s period of primary language acquisition, and may be partial or incomplete due to normal linguistic variation found during acquisition, due to a child’s level of progression through typical chronological development, or due to the presence of language disorders, like specific language impairment (SLI). In the current study, we ask whether characteristics of verbs make it more or less likely that children will correctly use an inflectional morpheme. The morphemes of interest in the current study were third person singular –s (3S) and past tense –ed (ED). Data for analysis were taken from a database of spontaneous language samples collected from 40 children (20 with SLI and 20 developing typically; Hoover, Storkel, & Rice, 2012). Spontaneous language samples were analyzed for the presence or absence of each morpheme in obligatory contexts. For each word item, the uninflected base word was additionally analyzed for a number of phonological and lexical variables. After comparing children with SLI to typically developing peers group differences emerged with respect to the effect of phonological and lexical variables. Moreover, different variables were determined to predict the 3S and ED morphemes. The results are discussed highlighting relevant theoretical and clinical implications.

The aim of this study was to investigate the effectiveness of a storybook retell technique to facilitate vocabulary acquisition in children educated in Māori immersion class settings. A second aim of the study was to explore the cultural responsiveness and pedagogical appropriateness of the intervention approach and the importance of relationship building (whakawhanaungatanga) to successful interventions. Nine children participated in the study. These children (aged between 5 and 8 years) were recruited from two Kura Kaupapa Māori settings in differing urban areas in New Zealand. The children entered the study on a rolling basis in groups of three. The first three participants to enter the study were recruited from the one classroom on the basis of their demonstrating specific language impairment (SLI). The second group of three participants attended a different classroom and these participants were recruited into the study as a result of identified delayed reading development (RD). The third group of three participants from a third classroom was selected as the participants exhibited typical spoken and written language development (TD). The intervention technique utilized in this study adopted a structured approach to teaching the meaning of pre selected vocabulary items that were embedded in class story books. Three different books were selected and each book was read by the teacher to the whole class three times during a one week period. The target vocabulary was highlighted each time it occurred in the story through the following techniques: an adult definition was given for the word, an antonym or synonym was given, and the meaning was acted out by the teacher or the picture detailing the meaning of the word in the book was highlighted. A single subject research design using pre-intervention, intervention and post intervention assessment probes for the target vocabulary items was employed to examine the effectiveness of the intervention in teaching the children the targeted vocabulary. Teacher interviews were also carried out to assess the appropriateness of the intervention in relation to the philosophy of the Kura Kaupapa and its pedagogical appropriateness and cultural responsiveness. The results suggested that the children in all three groups (SLI, RD and TD) made moderate gains in the acquisition of the target vocabulary supporting the hypothesis that targeting vocabulary in story book retelling at a whole class level will lead to acquisition of the vocabulary by the participants' exposed to the intervention. However, using a Two Standard Deviation method to evaluate the significance of each participant's change, the gains made for the RD and SLI participants were not significant. The TD participants did demonstrate a significant difference in the number of words correct. The teachers of the participants involved in the study reported positively on the effectiveness and appropriateness of the intervention for inclusion within the Kura Kaupapa and classroom programme. In particular, teachers' reported that as the intervention included each child in the class (as opposed to a withdrawal intervention model) the intervention was more appropriate for the philosophy of the Kura Kaupapa. The teachers' also reported the effectiveness of the intervention for the development of collaboration and relationship building between the teacher and researcher (a speech-language therapist. The data showed that the intervention investigated in this study was culturally responsive and pedagogically appropriate. It could be included as a component of the class programme as it was responsive to the philosophy of the Kura Kaupapa. The participants' did make moderate gains in the acquisition of the vocabulary (although not at a level to be considered significant for children with delayed development). Further research is necessary to explore the effectiveness of what may potentially be a useful intervention to enhance vocabulary development for children in Kura Kaupapa.

Background: This study formed part of a larger longitudinal research study by Jordaan (2009), who tracked the development of language for academic purposes in grade 1- 3 English Additional Language (EAL) and English First Language (EFL) learners attending English only programmes in Gauteng over a period of three years. These learners attended schools in two different educational contexts where there is a marked heterogeneity in the linguistic backgrounds of both the learners and teachers investigated. Results from Jordaan’s (2009) study revealed that some EAL and EFL learners appeared to be slow in the development of their academic language abilities (as no progress was evident over the period of three years), relative to their peers, and thus these learners may have a language impairment. Purpose: This study investigated in detail, these “slow to learn” EAL and EFL learners in the foundation phase, in order to determine whether they have a language impairment and to determine how the language impairment manifests in these learners. Participants: Sixteen learners (5 EFL learners and 16 EAL learners) who demonstrated no improvement in their academic language abilities from grade one to grade two as determined by their performance on the Diagnostic Evaluation of Language Variation Criterion Referenced (DELV-CR) test were the participants of this study. Method: The participants were assessed on the Automated Working Memory Assessment (AWMA) test, a Non Word Repetition test (Dollaghan & Campbell, 1998), a Sentence Repetition test (Redmond, 2005) and the Gray Oral Reading Test (GORT-4). Educators were also asked to rate these learners’ oral language, written language and reading comprehension abilities on a scale of 0- 5. The research design utilized was a non experimental, descriptive quantitative design, involving both correlational and comparative components. The data obtained was then analysed using descriptive and inferential statistics. Pearson correlation coefficients were calculated to establish whether there was a relationship between the cognitive processing and the language proficiency measures as well as the teacher ratings in order to provide information regarding these tests as assessment tools for EAL learners as well as to further enhance the validity of this study. Independent sample t-tests were also conducted to determine whether there were any significant differences between the EFL and EAL learners’ performance in the two different educational contexts, so as to establish whether bilingual learners with language impairment are more severely impaired than monolingual learners with language impairment. Results: Based on the analysis of these learners’ performance on the DELV-CR test, results indicated that all sixteen participants presented with SLI and were not just “slow to learn”. The EAL-SLI learners in both contexts performed poorly on the reading comprehension test and were rated lower than their aged matched peers on the teacher rating scales. Furthermore, when comparing these EAL-SLI learners’ performance on the DELV-CR test to the performance of the EFL-SLI learners, the EAL-SLI learners as a group appeared to have performed more poorly than the EFL-SLI learners on all three subtests. As significant differences were found between the EAL and EFL learners’ performance on the DELV-CR test, the results suggested that bilingual learners with SLI, who acquire a second language sequentially, are more impaired than monolingual learners with SLI. The EAL-SLI learners also presented with visuo-spatial short term and working memory deficits and even though a large majority of the learners presented with verbal short term and working memory difficulties, not all the learners presented with cognitive processing difficulties. This finding has implications for the theories of SLI. However, the sentence repetition task was found to be a useful tool in differentiating between the “slow to learn” EAL learners and EAL-SLI learners and furthermore this test also positively correlated with various sections of the DELV-CR test which adds to the value of this test as an assessment tool in EAL learners. Positive correlations were also found between the teacher ratings of the EAL-SLI learners and the subtests of the DELV-CR test which indicates that teachers have the ability to correctly identify learners with language learning difficulties. Positive correlations were also found between the digit repetition subtest, the non word repetition test and the sentence repetition test which adds to the validity of this study. Conclusion: The results obtained from this study demonstrated that bilingual learners with SLI who acquire a second language sequentially are additionally disadvantaged compared to their EFL-SLI peers in the acquisition of certain aspects of academic language. Furthermore, although research has shown that cognitive processing measures are less biased in the assessment of linguistically diverse learners, results indicated that the DELV-CR test identified more accurately, learners with language impairment whereas the cognitive processing measures provided contradictory and biased results with the verbal working memory subtest over identifying learners “at risk” for language impairment. Finally, the use of sentence repetition tasks in the differentiation between “slow to learn” and language impaired EAL learners proves to be promising.

This study aimed to explore the underlying basis of the communication difficulties in children (between 5.0 and 7.11 years) with high functioning pervasive developmental disorder (HFPDD) (n=26), compared to children with specific language impairment (SLI) (n=26), and children with no history of developmental difficulty (NDD) (n=26). The study looked at: whether different profiles could be obtained for the groups on comprehensive batteries of communication, cognitive processing and theory of mind; which areas measured were best correlated; and which measures best differentiated the groups. Comprehensive communication and theory of mind batteries were devised and conducted. Cognitive processing was measured using the Cognitive Assessment System (CAS) (Naglieri and Das, 1997). Data was analysed using descriptive statistics, analysis of variance, the Kruskal-Wallis test, Bonferroni t tests, frequency distributions, Pearson correlation coefficients and discriminant function analyses. Kappa coefficients and analysis of variance measures were carried out on 23% of the rated data in order to establish inter-rater agreement and acceptable levels of agreement were reached. On the communication assessment, the HFPDD group experienced the most difficulty on the measures of understanding abstract vocabulary, understanding conversation, pronoun alternation, higher level semantics, narrative ability and pragmatic ability. In contrast, the SLI group experienced the most difficulty on the measures of expressive grammar and narrative clarity. On the cognitive processing assessment, the HFPDD group experienced marked difficulty in the areas of planning and attention, while the SLI group experienced significant difficulty in the areas of successive processing and less marked but still significant difficulty in the area of planning. Within the HFPDD group, a group with simultaneous processing markedly stronger than successive processing, a group with successive processing markedly stronger than simultaneous processing, and a group with simultaneous and successive processing occurring at a similar level, were identified. The HFPDD group experienced significant difficulty on all the measures of theory of mind, although a limited number of HFPDD subjects did not experience difficulty. The SLI group experienced significant difficulty on the two theory of mind measures that were more verbally loaded. Strong correlations were found between receptive language, expressive semantics, narrative ability, pragmatic ability, planning, attention and theory of mind; and between expressive grammar and successive processing. Pragmatic ability, narrative ability, planning, and certain of the theory of mind measures best appeared to discriminate the groups. A combined model of language, cognitive and theory of mind processing is proposed to explain the differences between the HFPDD and SLI groups.

O Distúrbio Específico de Linguagem (DEL) é uma alteração que acomete o desenvolvimento da linguagem que não pode ser atribuído à defasagem sensorial, motora, intelectual, transtorno globais do desenvolvimento, privação social ou lesão cerebral evidente. Estudos comprovam que o desempenho de crianças com DEL é inferior ao de seus pares normais em provas de Memória de Trabalho (MT) e relacionam essa defasagem às dificuldades linguísticas destes sujeitos. É consenso que a memória de trabalho fonológica (MTF) é fundamental para o desenvolvimento da linguagem, porém, há divergências sobre o papel da memória de trabalho visual (MTV). Assim este estudo teve como objetivo comparar o desempenho de crianças com DEL e com Desenvolvimento Típico de Linguagem (DTL) em provas de MT e vocabulário receptivo; comparar o desempenho na Prova de Memória de Trabalho Fonológica (PMTF) e Teste Pictórico de Memória (TEPIC-M) verificando se há diferença em função do material ser apresentado por via auditiva ou visual e ainda, correlacionar o desempenho das crianças com DEL nas provas de MT e de vocabulário receptivo. Participaram do estudo 42 crianças sendo 14 delas com diagnóstico de DEL e 28 com DTL, pareadas pela idade cronológica, foram aplicados dois testes que avaliam a memória de trabalho (PMTF e TEPIC-M) e um teste que avalia vocabulário receptivo (Peabody Picture Vocabulary Test- PPVT-III). Para a análise estatística foram utilizados os testes t de Student para comparação entre os grupos e Correlação de Pearson para correlacionar os resultados entre as provas. Os resultados mostraram que as crianças com DEL apresentam desempenho inferior em relação aos seus pares normais em ambas as provas de MT, sendo que, em maior proporção na prova de PMTF, havendo correlação entre todos os testes aplicados. Assim conclui-se que crianças com DEL apresentam defasagem na MTF e na MTV, nesta última em menor proporção. Quanto maior a defasagem nas habilidades de memória, maior foi a defasagem no vocabulário destas crianças. Tanto crianças com DEL, como as com DTL apresentaram pior desempenho quando o estímulo foi apresentado por via auditiva comparado àquele apresentado por via visual. / The Specific Language Impairment (SLI) is a disorder that affects the language development and cant be attributed to lag sensory, motor, intellectual and pervasive developmental disorder, social deprivation or evident brain lesion. Studies show that the performance of SLI children is lower than their normal peers in Working Memory (WM) tests and relate this discrepancy to the linguistic difficulties of these subjects. There is consensus that phonological working memory (PWM) is critical to language development, but there are disagreements about the role of visual working memory (VWM). So this study aimed to compare the performance of children with SLI and typical language development (TLD) in WM tests and receptive vocabulary, to compare the performance in Phonological Working Memory Test (PWMT) and Pictorial Memory Test (PMT) checking whether there are differences depending on the material being presented through auditory or visual, still, to correlate the performance of children with SLI on receptive vocabulary tests and WM tests. The study included 42 children, 14 of them with SLI and 28 with TLD, paired with chronological age, were applied two tests that assessed working memory (PWMT and PMT) and a receptive vocabulary test (Peabody Picture Vocabulary Test - PPVT-III). For statistical analysis were used t of Student test for comparison between groups and Pearson Correlation to correlate the results between tests. The results showed that children with SLI perform below their peers in relation to normal in both WM tests, mainly on the PWMT, there was correlation between all tests. Thus it is concluded that children with SLI present deficits in PWM and VWM, the latter in a smaller proportion. The higher is the gap in their memory skills, the higher is the gap in the vocabulary of these children. Both children with SLI, as with TLD showed a worse performance when the stimulus was presented auditory compared to that presented by visual means.
