Introduction: Expressive vocabulary plays a vital role in child language development, and its assessment can be one of the essential indicators to identify language developmental delay, especially in children with Down syndrome. We developed a list of expressive vocabulary and compared the size and class of expressive vocabularies between typically developing and Down syndrome children. Materials and Methods: Expressive vocabulary of 150 children was examined  in  this study. A total of 120 typically developing Farsi-speaking children (in four age Groups, with   a 6-month interval) and 30 children with Down syndrome (aged 24-48 months) participated in this study. The parents of the children filled out the form that included 636 words from different vocabulary classes. These classes were based on studies that investigated language development in Farsi-speaking children. Results: The expressive vocabulary size in Farsi-speaking children was significantly higher than in Down syndrome children (P≤0.001). There was no statistically significant difference between boys and girls regarding expressive vocabulary size in two Groups of children. The size of nouns in all age Groups is more than other classes, and the size of conjunctions in all age Groups is less than the other ones. A direct correlation was found between age and the size of expressive vocabulary. Conclusion: According to the study findings, the list of expressive vocabulary can detect delays in developing expressive vocabulary.

The purpose of this study was to examine potential differences in the predictors of expressive vocabulary development between children with Down syndrome and typically developing children to support preparation for intervention development. An age cohort of 43 children with Down syndrome and 57 typically developing children with similar nonverbal mental age levels were assessed at three time points. Linear mixed models were used to investigate the predictors of expressive vocabulary over time. Both groups achieved progress in expressive vocabulary. The typically developing children had steeper growth than the children with Down syndrome (1.38 SD vs. 0.8 SD, p < 0.001). In both groups, receptive vocabulary, auditory memory, and the home literacy environment were significant predictors of development. In the children with Down syndrome, the phonological awareness and oral motor skills were also significant. Group comparisons showed that receptive vocabulary, auditory memory and oral motor skills were stronger predictors in the children with Down syndrome than in the typically developing children. These results indicate that children with Down syndrome are more vulnerable when it comes to risk factors that are known to influence expressive vocabulary than typically developing children. Children with Down syndrome therefore require early broad-based expressive vocabulary interventions.

Significant Difference

Children with Down Syndrome (DS) show developmental retardation of gross motor function including acquisition of oral movements related to eating and swallowing. To characterize the process of development/acquisition of eating/swallowing function of children with DS, interlabial pressure (IP) during taking food into the mouth was assessed. This study included 99 children with DS (birth to 4 year-old), and 112 age-matched control children showing typical development. IP during taking food into the mouth was measured as an objective index of lip closing function. The system for measuring IP during taking food into the mouth consisted of a strain gauge-pressure sensor connected to a strain-measuring device, which sent data to a personal computer installed with electromagnetic oscillograph software to display pressure waveforms. The DS and typically developing children were grouped into each age group and the data were compared between matched-age groups. IP during taking food into the mouth, pressure-time (PT), variation coefficient (VC) of IP during taking food into the mouth and VC of PT were analyzed using the unpaired t-test. Analyses showed a significantly higher IP during taking food into the mouth in the DS population than in the typically developing children in the 2 and 3 year old (P = .042 and .049, respectively) groups. No significant difference was observed between the DS and typically developing groups with respect to PT, VC of IP during taking food into the mouth or VC of PT for any age group. Children with DS showed a process of acquisition of lip closing function during taking food into the mouth similar to the process found in typically developing children, even though children with DS experience developmental retardation in gross motor and cognitive functions.

Audiologic Evaluation

Purpose Normative data regarding behavioral audiologic testing procedures are based upon the general population and often do not apply to children with Down syndrome (DS). Testing children with DS can be challenging, and outcomes may be unreliable due to their different cognitive demands and delays. The aim of this study was to assess optimal audiologic testing procedures for specific age groups of children with DS. Method This study used a retrospective investigation of 273 children with DS (145 boys, 128 girls; average age at evaluation = 5.92 ± 4.74 years) who received an audiologic evaluation during 2013 as part of their medical care at a large pediatric hospital (satellite facilities included). Results Age ranges for the completion of audiometry procedures in children with DS are provided. Average age to reliably complete behavioral testing in children with DS was delayed by up to 30 months compared to typically developing children. The majority of children with DS achieved at least good-to-fair reliability for audiologic results starting at 16 months (85.7%) and two ear results at 6–10 years (76.1%). Though not statistically significant, the use of a two-tester assistant compared to a single tester appeared to be helpful in obtaining reliable results. Conclusion The results provide a guide to optimal audiologic test procedures for children with DS, as the standard audiologic guidelines for typically developing infants and children do not apply.

The present study (a) addressed difficulties in speech fluency in children with Down syndrome and typically developing children at a similar non-verbal level and (b) examined the association between difficulties with speech fluency and language skills in children with Down syndrome. Data from a cross-sectional parent survey that included questions about children’s difficulties with speech fluency, as well as clinical tests from a national age cohort of 43 six-year-olds with Down syndrome and 57 young typically developing children, were collected. Fisher’s exact test, Student’s t-test, linear regression, and density ellipse scatter plots were used for analysis. There was a significantly higher occurrence of parent-reported difficulties with speech fluency in the children with Down syndrome. Higher language scores were significantly associated with a lower degree of difficulties; this association was strongest for vocabulary and phonological skills. Although difficulties with speech fluency were not reported for all children with Down syndrome, a substantially higher occurrence of such difficulties was reported compared to that for typically developing children. The significant association between difficulties with speech fluency and the level of language functioning suggests that speech fluency and language skills should be taken into consideration when planning treatment for children with Down syndrome.

Representational Gestures

Abstract In early communicative development, children with Down syndrome (DS) make extensive use of gestures to compensate for articulatory difficulties. Here, we analyzed the symbolic strategies that underlie this gesture production, compared to that used by typically developing children. Using the same picture-naming task, 79 representational gestures produced by 10 children with DS and 42 representational gestures produced by 10 typically developing children of comparable developmental age (3;1 vs. 2;9, respectively) were collected. The gestures were analyzed and classified according to four symbolic strategies. The two groups performed all of the strategies, with no significant differences for either choice or frequency of the strategies used. The item analysis highlighted that some photographs tended to elicit the use of the same strategy in both groups. These results indicate that similar symbolic strategies are active in children with DS as in typically developing children, which suggests interesting similarities in their symbolic development.

Abstract Despite a lack of consistent empirical evidence, there has been an ongoing assumption that intellectual disability is associated with reduced levels of motivation. The participants in this study were 33 children with Down syndrome ages 10–15 years and 33 typically developing 3–8-year-old children. Motivation was measured through observational assessments of curiosity, preference for challenge, and persistence, as well as maternal reports. There were no significant group differences on motivation tasks, but mothers of children with Down syndrome rated their children significantly lower on motivation than did parents of typically developing children. There were some intriguing group differences in the pattern of correlations among observations and parent reports. The findings challenge long-held views that individuals with intellectual disability are invariably deficient in motivation.

Communicative Behaviors

Many studies demonstrate that in typically developing (TD) children joint attention constitutes a prerequisite for language development. However, data on the development of joint attention and its relation to language development in Down syndrome (DS) are contradictory. The present study aims to examine joint attention in toddlers with DS as well as its association with language comprehension and production. Participants were 10 toddlers with DS (mean chronological age: 58 months) and 10 TD toddlers matched for language comprehension (mean chronological age: 32 months). Language Comprehension and language production were assessed using the Müllen Scales of Early Learning, expressive vocabulary was assessed using the Language Development Survey, and the communicative behaviors were assessed through observation of interactions with the mother in a semi-structured condition with toys. According to the findings, toddlers with DS exhibit significantly morejoint attention behaviors compared to TD toddlers. Moreover, it was shown that in toddlers with DS language production was significantly negatively correlated with initiating request gestures. Conclusively, it seems that in toddlers with DS the transition from pre-linguistic to linguistic period follows a similar developmental path as in TD toddlers, although a severe delay is observed.

AbstractThis study investigated how forty-six mothers modified their talk about familiar and unfamiliar nouns and verbs when interacting with their children with Down Syndrome (DS), language impairment (LI), or typical development (TD). Children (MLUs < 2·7) were group-matched on expressive vocabulary size. Mother–child dyads were recorded playing with toy animals (noun task) and action boxes (verb task). Mothers of children with DS used shorter utterances and more verb labels in salient positions than the other two groups. All mothers produced unfamiliar target nouns in short utterances, in utterance-final position, and with the referent perceptually available. Mothers also talked more about familiar nouns and verbs and labelled them more often and more consistently. These findings suggest that mothers of children in the early period of language development fine-tune their input in ways that reflect their children's vocabulary knowledge, but do so differently for nouns and verbs.
