Using a word association task to investigate semantic depth in swedish-speaking children with developmental language disorder.

We examined word associations in Swedish children with Developmental Language Disorder (DLD) compared to their typically developing (TD) peers. Furthermore, the study aimed to explore the dimensions of vocabulary knowledge (breadth, depth, and fluency) in these children. Fifty children (15 DLD and 35 TD) participated in the study, aged six to nine years. This age span is commonly associated with substantial lexical reorganisation, by some referred to as the syntagmatic-paradigmatic shift. Fifty items from the Kent-Rosanoff list were used to elicit word associations (say the first word that comes to mind). Word associations were coded as paradigmatic (lion-tiger), syntagmatic (chair-sit), phonological (moon-poon), and other/no answer (foot-hello/bed- -). A semantic depth score (paradigmatic and syntagmatic associations) was calculated and analysed. The children with DLD showed significantly lower semantic depth scores than their TD peers, in line with previous research in English-speaking children. However, the vocabulary dimensions were uniformly affected for the DLD group, contradicting previous findings of semantic depth as a particular area of weakness in this group.

Communication ability and communication methods in children with cerebral palsy.

AIM: To investigate if communication ability and method were related to each other and to age, sex, gross motor function, or manual ability in children with cerebral palsy. METHOD: This cross-sectional study used data registered in the Swedish Cerebral Palsy Surveillance Program registry, involving 3000 children aged 0 to 18 years. Pearson's χ2 test and Spearman's correlation were used to test associations between variables. RESULTS: Communication ability and method were related to each other and to age, gross motor function, and manual ability. Aided communication methods were more frequently used among older children. The more functional the communication was, the less use of unaided communication occurred. Different communication methods were used across all Communication Function Classification System (CFCS) levels. Speech was most common in more functional levels, used by 72% of the children. Forty-five per cent were considered effective communicators in all environments. For classification of communication level and method, some recurring registration errors were made by the raters. INTERPRETATION: Some raters may need clarification on interpretations of CFCS instructions. Results indicate that children should be presented to aided augmentative and alternative communication and manual signs earlier and to a greater extent.

Theory of Mind and Executive Functions in Young Bilingual Children.

Few studies have explored the relationship between theory of mind (ToM), executive function (EF), and bilingualism at the same time. In this study 14 young bilingual children were compared with monolingual children on a test battery composed of 5 ToM tests, 5 EF tests, and 1 test of general language ability. The result showed that despite significantly lower verbal ability, the bilingual children outperformed the monolingual ones on tests of EF. There were no differences in ToM performance. The authors argue that there is a strong relationship between bilingualism and EF, but, contrary to results from earlier studies, they could not find any relationship between bilingualism and ToM. EF did not predict ToM performance. Lack of a significant relationship could be due to the children's young age and consequently their low scores on the ToM tasks.

Self-reported health, use of alcohol and illicit drugs, and criminality among adults with foetal alcohol syndrome.

AIMS: To investigate self-reported physical and psychiatric problems, use of alcohol and illicit drugs, as well as conviction, and being a victim, of crime in adults with foetal alcohol syndrome (FAS). METHODS: Interviews with 20 adults, aged 30±8 years with FAS diagnosis (65% female) and an age-and-gender-matched comparison group. Measures used were the Addiction Severity Index interview, the Beck Depression Inventory Scale and the Beck Anxiety Inventory Scale. RESULTS AND CONCLUSIONS: Adults with FAS need healthcare for depression and suicidal ideation, which occurred commonly, but problems with use of alcohol and illicit drugs were not more common in the FAS group. Although self-reported physical health problems were not more common in the FAS group, their number of days with sickness leave indicated that they are often in too poor a physical condition to work. A majority of the FAS group had been victims of crime, which makes this an important topic for further research. The groups did not differ in crime conviction rates. Everyone in the study group had been diagnosed with FAS; a diagnosis may give access to social welfare interventions. More individuals within the FAS disorders spectrum need to be identified to be given access to efficient interventions.

A descriptive study of lexical organisation in bilingual children with language impairment: Developmental changes.

PURPOSE: This study aimed to describe the development of Arabic and Swedish lexical organisation in bilingual children with language impairment (BLI). METHOD: Lexical organisation was assessed through word associations in 10 BLI and 10 bilingual children with typical development (BTD), aged 6;2-8;0 years, matched for age and gender. The participants were assessed twice, with a 1-year interval. Word associations were coded as paradigmatic, syntagmatic, phonological, other and no answer. This study reports analyses of the semantically-related syntagmatic and paradigmatic associations. Using repeated measures ANOVA, main and interaction effects of Group, Time and Language were examined for paradigmatic and syntagmatic associations separately. RESULT: The interaction between Group and Time was significant for both associations. The BLI group increased syntagmatic associations from time 1 to time 2, while the BTD group increased paradigmatic associations. Results showed a significant main effect of Language for both types of associations, with better performance in Swedish. Significant Group by Language interactions resulted from lower Arabic than Swedish syntagmatic and paradigmatic scores for the BLI and BTD groups, respectively. CONCLUSION: Differing developmental trajectories indicate that bilingual children with LI develop lexical organisation at a slower pace than bilingual peers with typical language development.

Story retelling and language ability in school-aged children with cerebral palsy and speech impairment.

BACKGROUND: Research on retelling ability and cognition is limited in children with cerebral palsy (CP) and speech impairment. AIMS: To explore the impact of expressive and receptive language, narrative discourse dimensions (Narrative Assessment Profile measures), auditory and visual memory, theory of mind (ToM) and non-verbal cognition on the retelling ability of children with CP and speech impairment. METHODS & PROCEDURES: Fifteen speaking children with speech impairment (seven girls, eight boys) (mean age = 11 years, SD = 1;4 years), and different types of CP and different levels of gross motor and cognitive function participated in the present study. Story retelling skills were tested and analysed with the Bus Story Test (BST) and the Narrative Assessment Profile (NAP). Receptive language ability was tested with the Test for Reception of Grammar-2 (TROG-2) and the Peabody Picture Vocabulary Test - IV (PPVT-IV). Non-verbal cognitive level was tested with the Raven's coloured progressive matrices (RCPM), memory functions assessed with the Corsi block-tapping task (CB) and the Digit Span from the Wechsler Intelligence Scale for Children-III. ToM was assessed with the false belief items of the two story tests "Kiki and the Cat" and "Birthday Puppy". OUTCOMES & RESULTS: The children had severe problems with retelling ability corresponding to an age-equivalent of 5;2-6;9 years. Receptive and expressive language, visuo-spatial and auditory memory, non-verbal cognitive level and ToM varied widely within and among the children. Both expressive and receptive language correlated significantly with narrative ability in terms of NAP total scores, so did auditory memory. CONCLUSION & IMPLICATIONS: The results suggest that retelling ability in the children with CP in the present study is dependent on language comprehension and production, and memory functions. Consequently, it is important to examine retelling ability together with language and cognitive abilities in these children in order to provide appropriate support.

Investigating executive functions in children with severe speech and movement disorders using structured tasks.

Executive functions are the basis for goal-directed activity and include planning, monitoring, and inhibition, and language seems to play a role in the development of these functions. There is a tradition of studying executive function in both typical and atypical populations, and the present study investigates executive functions in children with severe speech and motor impairments who are communicating using communication aids with graphic symbols, letters, and/or words. There are few neuropsychological studies of children in this group and little is known about their cognitive functioning, including executive functions. It was hypothesized that aided communication would tax executive functions more than speech. Twenty-nine children using communication aids and 27 naturally speaking children participated. Structured tasks resembling everyday activities, where the action goals had to be reached through communication with a partner, were used to get information about executive functions. The children (a) directed the partner to perform actions like building a Lego tower from a model the partner could not see and (b) gave information about an object without naming it to a person who had to guess what object it was. The executive functions of planning, monitoring, and impulse control were coded from the children's on-task behavior. Both groups solved most of the tasks correctly, indicating that aided communicators are able to use language to direct another person to do a complex set of actions. Planning and lack of impulsivity was positively related to task success in both groups. The aided group completed significantly fewer tasks, spent longer time and showed more variation in performance than the comparison group. The aided communicators scored lower on planning and showed more impulsivity than the comparison group, while both groups showed an equal degree of monitoring of the work progress. The results are consistent with the hypothesis that aided language tax executive functions more than speech. The results may also indicate that aided communicators have less experience with these kinds of play activities. The findings broaden the perspective on executive functions and have implications for interventions for motor-impaired children developing aided communication.

Narrative ability in children with cerebral palsy.

In a previous study a group of children with cerebral palsy (CP) were found to have considerable difficulties with narratives, performing several standard deviations below the criteria for the Information score of the Bus Story Test (BST). To examine in depth the performance of children with CP and a control group with typically developing (TD) children on a narrative task, in order to search for possible underlying causes to the problems in the CP group. The results of the BST for 10 children with CP, mean age 7;11 years, were investigated. The analysis of the BST was supplemented with the use of the Narrative Assessment Profile (NAP) and quantitative analyses of number of words, mazes, propositions, types of conjunctions and story elements. A significant relationship between the explicitness dimension on the Narrative Assessment Profile and the BST Information score in the CP group suggested that the problems could be derived to a limited use of cohesion and a scarcity of essential information. Compared to the CP group, the TD group used significantly more causal conjunctions. The results indicate a general problem with cohesion at the textual level in the CP group. A further finding was the occurrence of a positive correlation between the use of mazes and the BST Information score in the CP group. These results have implications for the design of a more specific intervention for children, where the NAP was found to be a valuable tool in combination with the BST or other assessment materials. Further, it is shown that mazes, mostly regarded as a behaviour that not enhances speech production, for some children can be used as a means to find necessary words and pieces of information.

An analysis of reading and spelling abilities of children using AAC: Understanding a continuum of competence.

The over-representation of reading and spelling difficulties in children with complex communication needs has been well documented. However, most of the studies reported have indicated that at least some children using augmentative and alternative communication (AAC) can achieve and demonstrate effective literacy skills, highlighting the heterogeneity of this group. This paper presents findings from a cross-linguistic study of 14 Swedish and 14 Irish children with cerebral palsy who use AAC, outlining their performance on a range of phonological awareness, reading, and spelling tasks developed for the purposes of the study. All participants were referred to the study as functioning in the average range of intellectual ability. Of the 28 participants, eight were classified as good readers, on the basis of their success on tasks involving connected text; while 10 presented with single-word reading skills; and 10 were categorized as non-readers. This paper explores the similarities and differences within and across these groups, in terms of associated skills and experiences. While analyses of group data suggests some common abilities and difficulties, exploration of individual profiles highlights the heterogeneity of the participants' profiles, suggesting a need for detailed individual assessment and interventions.

Basic reading skills in Swedish children with late developing language and with or without autism spectrum disorder or ADHD.

Reading skills at age 7-8 years were examined in a community-representative sample of 21 screened and clinically examined children with language delay (LD) followed prospectively from 2.5 years of age. The present study aimed to (1) determine whether these children with a history of LD had deficits in basic reading skills, i.e. decoding and comprehension, compared to the age norms of standardized tests, (2) analyze if there was a relationship between reading outcome and neuropsychiatric diagnosis by comparing three subgroups of children, LD pure, LD+ASD (autism spectrum disorder) and LD+ADHD, and, (3) determine what language measures at age 6 years were associated with the 7-8-year reading outcome. Both decoding and comprehension of single word reading were significantly below the norm for the whole LD group, where children with LD+ASD scored lowest, and children with LD highest. However, the differences between the three groups did not reach significance. Two reader groups were identified according to the results of word decoding and comprehension, respectively, resulting in the same 7 children. ANOVA revealed that the only differences on the 6-year language tests between the two groups were found on color naming and word memory. This study has shown that children with LD and subsequently identified neurodevelopmental problems such as ASD and ADHD experience continued deficits, demonstrated also in reading skills and that the picture of the reading problems seemed to resemble those of typically developing children.

Theory of mind in children with severe speech and physical impairments.

The development of a person's ability to understand other's thoughts and feelings, so-called "theory of mind" (ToM), is subject to study. Children with communicative disabilities have exhibited problems in this respect, highlighting the role of language in the development of ToM. In this study, ToM was studied in children with cerebral palsy and severe speech impairments. Two tasks, differently dependent on verbal abilities, were used. The results were compared to those of a mental age matched group. The groups differed significantly on the verbally dependent task while difference in performance did not reach significance on the less verbally dependent one. The results are discussed in terms of a delayed development of ToM in children with severe speech and physical impairments, dependent on verbal abilities.

Speech and satisfaction with outcome of treatment in young adults with unilateral or bilateral complete clefts.

Thirty-five young adults (22-32 years old, mean 25) born with complete unilateral or bilateral clefts participated in a follow-up of speech, appearance, and teeth after treatment. They completed a questionnaire about their satisfaction with their speech, nose, lip, and teeth on visual analogue scales, and indicated on two overall questions how often they thought about their cleft, and how often they were asked questions about their speech, nose, or lip. Their speech was recorded and assessed blindly and independently by two speech and language pathologists. Participants' satisfaction with their speech did not correlate significantly with the speech assessments. Satisfaction with the nose had the highest correlation with the overall questions. No participant indicated more dissatisfaction with speech than the midpoint of the scale, making conclusions about covariance between satisfaction with speech and the overall questions difficult.

Reading and spelling abilities in children with severe speech impairments and cerebral palsy at 6, 9, and 12 years of age in relation to cognitive development: a longitudinal study.

Development of literacy skills was studied in six children (one male, five females) with severe speech impairments and cerebral palsy (CP). These skills were related to intellectual development, phonological abilities, and short-term memory. Three of the children were diagnosed with dystonia, and three with diplegia. They had no, or severely restricted, independent mobility (Gross Motor Function Classification System Level IV for four children and Level V for two), and severe fine motor problems, including difficulty with pointing. As they had no intelligible speech, the Bliss system was the primary communication mode. Assessments were made at approximately 6, 9, and 12 years of age. The results revealed that the children had difficulties acquiring literacy skills, although intellectual level and phonological ability predicted otherwise. Positive development during the first 3 years was followed by an arrest. A conspicuous decrease in IQ points was also found. Thus, phonological ability does not seem to have the same predictive power for literacy development in children with severe speech impairments and CP as in typically developing children. Further studies are needed to clarify the role of phonological abilities, working memory, and strategies used in literacy acquisition in these children. Such studies might also clarify the importance of articulatory abilities in early literacy acquisition.
