Williams syndrome is a neurodevelopmental disorder associated with a characteristic physical and behavioural phenotype. The first formal reports of the reading ability of individuals with Williams syndrome were published in the late 1980s. International Journal of Language and Communication Disorders. In the one study that addressed mastery motivation of children with WS, preschoolers with WS were found to have significantly lower mastery motivation than did age-matched children with Down syndrome (DS), even though the children with DS had significantly lower intellectual abilities. Reading ability was measured with the Neale Analysis of Reading (Neale, 1966), which includes Reading Accuracy and Reading Comprehension subscales. performed relatively well on the Comprehensive Test of Phonological Processing (CTOPP; Wagner, Torgesen, & Rashotte, 1999); mean standard score on Elision (syllable or phoneme deletion) was in the borderline range, and mean standard scores on Segmenting Words and Segmenting Nonsense Words were in the low average range. Relative to other groups with similar levels of intellectual disability, individuals with Williams syndrome show a relative strength in verbal short-term memory. This study characterizes the developmental and adaptive behavior features of 16 . Mean DAS-II GCA was 63.14 (SD = 11.58, range: 39 98). This misperception may be exacerbated by the facts that overall IQ scores mask uneven patterns of strengths and weaknesses and that developmental milestones, especially the relation between referential gestures and the onset of referential language, may not proceed in the typical order. Three of the studies described above (Devenny et al., 2004; Edgin, 2003; Wang & Bellugi, 1994) also assessed backward digit recall. Language symptoms of developmental language disorders: An overview of This assumption is highly problematic for children with WS, who typically begin to produce referential language prior to producing referential communicative gestures. The correlation between backward digit recall and TROG performance was significantly higher for the Williams syndrome group than for a group of typically developing children matched to the Williams syndrome group for number of blocks correct on the TROG. In the next section, I describe the results of the studies that have been conducted on the reading abilities of individuals with Williams syndrome. Bellugi U, Marks S, Bihrle A, Sabo H. Dissociation between language and cognitive functions in Williams syndrome. Address for Correspondence: Carolyn B. Mervis, Ph.D., Department of Psychological and Brain Sciences, 317 Life Sciences Building, University of Louisville, Louisville, KY 40292, Comprehension monitoring (knowing when you have not understood what you have read, and knowing what to do to fix the situation), Cooperative learning (working with another child/children to improve both comprehension and social skills related to literacy and learning), Graphic organizers (use of visual representation as a memory aid for text content and organization), Story structure (instruction in story components and sequences, including use of story maps), Question answering (understanding what type of material is needed to answer specific questions, including when to look back at the text and when the answer requires background knowledge or needs to be inferred), Question generation (posing specific types of questions to oneself to increase ones awareness of whether the material read has been understood). How can gene variants affect health and development? Palacios-Verdu MG, Segura-Puimedon M, Borralleras C, Flores R, Del Campo M, the contents by NLM or the National Institutes of Health. Laing et al. Language abilities in Williams syndrome: A critical review Combining working memory training and comprehension strategy training should facilitate the development of reading comprehension. Learning to read Hebrew is likely more challenging for individuals with Williams syndrome than learning to read languages that use the Roman alphabet. Ehri provides the example of an S drawn as the body of Sammy Snake as in the Letterland program (Wendon, 1992). 2009 April-June; 29(2): 149169. Laws G, Bishop DVM. If this condition is not treated, the aortic narrowing can lead to shortness of breath, chest pain, and heart failure. Williams syndrome (WS) is a relatively rare microdeletion disorder that occurs in as many as 1:7,500 individuals. Fluent reading frees cognitive resources so that the child can focus on comprehension. Although the ultimate level of reading achievement will be affected by a childs intellectual ability, among other factors, most if not all children with Williams syndrome should be able to learn to read if effective instruction is provided. 2006 Aug;63(16):1867-75. doi: MacArthur Communicative Development Inventories: Users guide and technical manual. He found a strong correlation between age at onset of rhythmic hand banging and canonical babble and between the onset of canonical babble (mean age of onset in his study: 17.7 months) and a 25-word expressive vocabulary for children with WS (mean age: 22.9 months). Many affected people have dental problems such as teeth that are small, widely spaced, crooked, or missing. In the second, I summarize the results of the studies that have been conducted on the reading abilities of individuals with Williams syndrome. Eckert MA, Galaburda AM, Mills DL, Bellugi U, Korenberg JR, Reiss AL. In sharp contrast, most children in the Whole Word group read below the level expected for their GCA. Udwin, Yule, and Martin (1987) assessed the intellectual and reading abilities of 44 children with Williams syndrome aged 6 16 years. impairment? Williams Syndrome - Developmental and Behavioral Pediatrics - Golisano From early reports on Williams syndrome to re-cent ones, performance on the PPVT has repeatedly yielded the highest mean standard score for any stan-dardized assessment. Further evidence of difficulty in event sequencing is provided by the inclusion of basic sequencing goals and/or goals addressing the comprehension and appropriate use of temporal terms such as before/after in the Individualized Education Programs (IEPs) of almost all children with Williams syndrome in preschool or elementary school and for many children in middle school. American Journal of Medical Genetics Part C. John AE, Rowe ML, Mervis CB. Reilly J, Losh M, Bellugi U, Wulfeck B. Language and Literacy Development of Children With Williams Syndrome The .gov means its official. However, some studies of typically developing children have failed to find semantic effects using this paradigm (e.g., McKague, Pratt, & Johnston, 2001), suggesting the importance of further research to address the question of the relative importance of phonological and semantic skills for individuals with Williams syndrome in learning to read. No abstract available. Epub 2005 For preschool and school-age children, a full assessment of all aspects of language and communication, including extensive observation of the childs interactions with teachers and peers in both formal and informal settings, is critical to determining if the child would benefit from language therapy and the level of intensity needed. Seattle; 1993-2023. (2003) stated that phonics instruction should be helpful for children with Williams syndrome, given the strong relations between their phonological awareness abilities and their reading abilities. Journal of the International Neuropsychological Society. Williams syndrome (WS) is a rare genetic disorder. compared a group of 4 12-year-old children with Williams syndrome to groups of CA-matched typically developing children and CA-matched children with specific language impairment. An official website of the United States government. Udwin and Yule (1990) reported that 37% of the children with WS in their study met criteria for hyperverbal speech (excessive use of stereotyped phrases, over-familiarity, introduction of irrelevant experiences, perseverative responding). Four types of skills are assessed: rhyming, blending, deletion, and phoneme identification & word segmentation. American Journal on Intellectual and Developmental Disabilities. Menghini et al. Hillier LW, Fulton RS, Fulton LA, Graves TA, Pepin KH, Wagner-McPherson C, et al. In: McCardle P, Chhabra V, editors. The DNA sequence of chromosome 7. Mervis CB, Morris CA. Laing et al. Williams syndrome (WS) is a clinical condition, involving cognitive deficits and an uneven language profile, which has been the object of intense inquiry over the last decades. How are genetic conditions treated or managed? Age at acquisition of a 10-word expressive vocabulary was below the 5th percentile for all 13 children; age at acquisition of 50- and 100-word expressive vocabularies was below the 5th percentile for 12 of 13. We believe that: If your 4-8 year old child with WS gets upset by brushing hair, hand dryers, flushing of toilets, blenders, loud noises, or in other specific predictable situations, they may be a fit for a new study. Some of the strategies suggested above may also be helpful in teaching relational terms to older children. Comprehensive Test of Phonological Processing. syndrome: a unique window to genetic influences on cognition and behaviour. Language and communicative development in Williams syndrome. In: Mazzocco MMM, Ross JL, editors. Menghini et al. Children with Williams syndrome, a rare neurodevelopmental disorder caused by deletion of ~25 genes on chromosome 7q11.23, evidence large individual differences in both broad language and reading abilities. Kamil ML. All but the oldest participant was able to decode and comprehend at least at the mid-1st grade level; median grade level was mid-2nd grade. Individuals with Williams syndrome found the same types of grammatical constructions difficult to comprehend whether they were learning English, Hungarian, or Italian. This finding has held across English (Grant et al., 2002; Mervis et al., 2003; Udwin & Yule, 1990; Zukowski, 2004), German (Gosch, Stding, & Pankau, 1994), Hungarian (Lukcs, 2005), and Italian (Volterra, Capirci, Pezzini, & Vicari, 1996; Volterra, Caselli, Capirci, Tonucci, & Vicari, 2003). First, the majority of individuals with Williams syndrome have intellectual abilities in the borderline to mild disability range; severe intellectual disability, rather than being the norm, is quite rare (e.g., Bellugi, Lichtenberger, Jones, Lai, & St. George, 2000; Mervis & John, in press; Mervis & Morris, 2007; Meyer-Lindenberg, Mervis, & Berman, 2006; Searcy, Lincoln, Rose, Klima, & Bavar, 2004). Comparison of grade equivalent scores indicated a small and nonsignificant increase for decoding and a small but significant decrease for comprehension. In striking contrast to their performance on concrete vocabulary measures, the performance of children with Williams syndrome on relational vocabulary measures is very low. The meta-analysis results indicated that systematic phonics instruction (teaching of all major letter-sound correspondences, including consonants, vowels, and digraphs, in a clearly-defined sequence) was more effective than either whole word (having children memorize whole words; sometimes referred to as the look-say or sight-word approach) or whole language (focusing on meaning, with letter-sound correspondences taught incidentally and in context, only as needed) approaches. sharing sensitive information, make sure youre on a federal doi: Parental ratings on five characteristics differentiated a group of 8 10-year-olds with WS from an age and IQ-matched group of children with other developmental disabilities, successfully classifying 96% of the children in the WS group and 85% of the children in the comparison group. World Congress on Chromosome Abnormalities; San Antonio, TX. Epub 2015 Feb 6. In: Shapiro BK, Accardo PJ, editors. Although language abilities generally are a strength in older children and individuals with WS, almost all young children with WS show a significant delay at the start of language development. The few studies of these topics involving individuals with Williams syndrome are described below. Studies of English-speaking children with this syndrome almost always use a version of the Peabody Picture Vocabulary Test (PPVT; e.g., Dunn & Dunn, 1981, 1997) to assess receptive concrete vocabulary. Levy and Antebi (2004) indicated that children with Williams syndrome and, more generally, children with intellectual disability, may benefit from an explicit phonics approach rather than a whole word approach to reading instruction. Del Campo M, Antonell A, Magano LF, Munoz FJ, Flores R, Bayes M, Perez Jurado Williams syndrome (WS) is a neurodevelopmental disorder that causes deficits in adaptive behavior, difficulties eating and sleeping, cognitive delays, and delayed development. Before Pediatrics. (1996) reported similar findings based on a comparison of the performance of children and adolescents with Williams syndrome on the Italian version of the TROG to that of MA-matched typically developing children. Losh et al. Mervis CB, John AE. 2005 Nov 18;310(5751):1184-7. doi: 10.1126/science.1116142. In the initial studies of the reading abilities of individuals with Williams syndrome, researchers examined performance on standardized measures of reading and IQ. American Journal of Medical Genetics Supplement. Williams Syndrome. Laing E, Hulme C, Grant J, Karmiloff-Smith A. 10.1016/j.jpeds.2016.08.027. This pattern includes relative strengths in two areas that are strongly related to single-word reading for children in the general population: phonological processing and concrete vocabulary and considerable weakness in areas that are strongly related to reading comprehension: relational concepts, receptive grammar, verbal working memory, comprehension monitoring, and discourse-related skills. Such claims have, in turn, been. Relational/conceptual vocabulary includes terms for both basic relational concepts (e.g., spatial, temporal, quantitative, and dimensional terms) and more advanced relational concepts such as conjunctions and disjunctions (e.g., and, although, neither nor). Communication and language acquisition: Discoveries from atypical development. Supravalvular aortic stenosis is a narrowing of the large blood vessel that carries blood from the heart to the rest of the body (the aorta). Sensory modulation problems, including difficulty with auditory filtering and hypersensitivity to sound, also are very common (John & Mervis, 2010). The pattern was similar to that for 4-year-old typically developing children (Gathercole, 1995) but differed from that for typically developing 5-year-olds in a manner that suggested that the Williams syndrome group was relying more heavily on memory and less on semantics in acquiring vocabulary; the authors considered this a less mature pattern. The paradoxical nature of the social, personality, and psychopathology characteristics of children with WS was highlighted in one of the first publications on this syndrome. More extreme versions of this position were taken by several academicians who had not worked directly with individuals with Williams syndrome. American Journal of Speech-Language Pathology. von Arnim G, Engel P. Mental retardation related to hypercalcaemia. Reilly et al. Klein-Tasman BP, Mervis CB. Consistent with the first three MPQ characteristics, parents of children with WS commonly report that their child never showed stranger anxiety, that he or she is widely known and well liked in their community, and that their childs smile can light up a room. Children with WS often use these same characteristics to avoid having to put forth effort on tasks that they find difficult or frustrating (Jrvinen-Parsley et al., 2008). In the following paragraphs, the results of the studies are compared and contrasted. 1 October 2004 Chapter All in good time: a window of opportunity for first language acquisition Julia Herschensohn Language Development and Age Published online: 22 September 2009 Article Expressive language style among adolescents and adults with Williams syndrome Loss of the GTF2IRD1 gene may also contribute to the distinctive facial features often associated with this condition. Working memory holds the most recent material read, allowing the child to integrate this material into the ongoing mental-model construction. In the first two sections of this article, I described the pattern of broad language strengths and weaknesses characteristic of individuals with Williams syndrome and then summarized the available data on the reading abilities of individuals with this syndrome. Mervis CB, Becerra AM. The correlations involving elision and word segmentation remained significant even after controlling for KBIT Matrices ability. Language and emotional abilities in children with Williams syndrome an syndrome. Of these characteristics, three (gregarious, people-oriented, visible) fit with the first part of von Arnim and Engels statement, and two (tense, sensitive) with the second. Oakhill, Cain, and Bryant (2003; Oakhill & Cain, 2007), reporting the results of a longitudinal study of children in the general population, indicated that after taking into account vocabulary ability and IQ, performance on the TROG was not related to reading comprehension for 7 8-year-olds but was related to reading comprehension a year later. The onset of language development is nearly always delayed for children with WS. Masataka N. Why early linguistic milestones are delayed in children with Williams syndrome: late onset of hand banging as a possible rate-limiting constraint on the emergence of canonical babbling.
