“…By contrast, the visuospatial STM skills of individuals with DS are usually found to be equal that of MA-matched groups (e.g. Brock & Jarrold, 2005;Visu-Petra, Benga, Ţincaş, & Miclea, 2007), with corresponding deficits reported on verbal STM tasks (e.g. Vicari, Marotta, & Carlesimo, 2004).…”

“…These opposite STM findings have been reinforced by studies comparing the two populations directly (Jarrold, Baddeley, & Hewes, 1999;Kittler et al, 2008;. Nevertheless, although the findings seem to suggest patterns of verbal and visuospatial STM development that differ both within and between the two groups, no study to date has attempted to plot STM performance in both domains against wider developmental indices (although see Brock & Jarrold, 2005, who examined the level of concurrence in developmental variation across the two domains). This would enable an assessment of how groups' performances may change across time, and whether developmental differences across the verbal and visuospatial domains may characterise STM.…”

“…Nouns usually have a final position, and verbs, medial position. This later occurrence could add more difficulties to children and adolescents with DS, since learning and use are related to the auditory working memory, which is hindered in this population 13,[15][16][17][18] . Participants' performance in the present study confirms these findings.…”

“…According to the authors, the short-term auditory memory directly interferes in expressive and receptive language in this population. The ability to remember phonemic sequences in a new word during vocabulary acquisition or the sequence of morphosyntactic components in an utterance is related to this type of memory 13,15,16,18 .On the other hand, the short-term visuospatial memory, which processes information related to spatial and visual properties, is usually less impaired than the auditory memory 4,16 .…”

“…To explain these alterations, studies have pointed out that, due to the cognitive deficit, children with DS have attention and working memory deficits, involving both auditory and visuospatial memory [13][14][15][16][17] . According to the authors, the short-term auditory memory directly interferes in expressive and receptive language in this population.…”

Clinical Trials registration number: NCT 00952354Conflict of interest: non existent typical development (TD), and literature indicates a relationship between lexicon and grammar. It is reported greater difficulties in functional words, such as articles, pronouns, prepositions and conjunctions, which have greater grammatical load, than in words with semantic content, such as nouns, verbs, and adjectives. In addition, these children have difficulties combining words and dealing with morphosyntactic rules, which have implications in phrasal structure [1][2][3][4][5][6][7][8][9] .The use of Mean Length Utterance -MLU 10 as a measure of language development in children with DS corroborates these difficulties, and indicates frequent omission of grammatical morphemes, particularly of functional words, resulting in ABSTRACT Purpose: to present and to discuss the use of augmentative and alternative communication as a therapeutic tool with the morphosyntax with adolescents with Down syndrome. Methods: this pilot study monitored during 12 months four adolescents chronologically aged between 13 and 15 years and mentally aged between 5 and 6 years. It were analyzed the initial and the final assessments, situations of free interaction between the participant and the caregiver videotaped during 30 minutes. The speech samples were analyzed as MLU values considering morphemes and words, comparing both the two situations. All of the participants were submitted to the same procedures during the therapeutic interventions. Picture Communication Symbols (PCS) has been used and the symbols were organized according to a simple syntactic structure (substantive + verb + complement) with a gradual extension, and the elements were rated at the following order: articles, prepositions, pronouns (personals, possessives and demonstratives), and conjunctions. Each therapeutic session was recorded in specific protocol. It was used the Wilcoxon test and the p value considered was 5%. Results: spites there were no statistical significant differences, increase in number of morphemes and words used between the both assessments was observed. This improve was represented by the worked elements, including prepositions and conjunctions beyond substantives and verbs. For personal pronouns there was tendency to significance (p=0,068). Conclusion: the communication system showed to be a therapeutic tool to improve the use of syntactic elements in statement structures, as articles, prepositions and conjunctions, which use for individuals with Down syndrome are difficult.

Individuals with Down syndrome (DS) commonly possess unique neurocognitive and neurobehavioral profiles that emerge within specific developmental periods. These profiles are distinct relative to others with similar intellectual disability (ID) and reflect underlying neuroanatomic findings, providing support for a distinctive phenotypic profile. This review updates what is known about the cognitive and behavioral phenotypes associated with DS across the lifespan. In early childhood, mild deviations from neurotypically developing trajectories emerge. By school-age, delays become pronounced. Nonverbal skills remain on trajectory for mental age, whereas verbal deficits emerge and persist. Nonverbal learning and memory are strengths relative to verbal skills. Expressive language is delayed relative to comprehension. Aspects of language skills continue to develop throughout adolescence, although language skills remain compromised in adulthood. Deficits in attention/executive functions are present in childhood and become more pronounced with age. Characteristic features associated with DS (cheerful, social nature) are personality assets. Children are at a lower risk for psychopathology compared to other children with ID; families report lower levels of stress and a more positive outlook. In youth, externalizing behaviors may be problematic, whereas a shift toward internalizing behaviors emerges with maturity. Changes in emotional/behavioral functioning in adulthood are typically associated with neurodegeneration and individuals with DS are higher risk for dementia of the Alzheimer's type. Individuals with DS possess many unique strengths and weaknesses that should be appreciated as they develop across the lifespan. Awareness of this profile by professionals and caregivers can promote early detection and support cognitive and behavioral development.

Serial order reconstruction in Down syndrome: evidence for a selective deficit in verbal short‐term memory

Abstract: The results provide strong evidence that Down syndrome is associated with a selective deficit in verbal short-term memory, and a deficit in verbal serial order memory in particular. Implications for the language difficulties associated with Down syndrome are discussed.
