Autism spectrum disorder (ASD) and specific language impairment (SLI) are two neurodevelopmental disorders characterized by deficits in verbal and nonverbal communication skills. These skills are thought to develop largely through implicit-or automatic-learning mechanisms. The aim of the current paper was to investigate the role of implicit learning abilities in the atypical development of communication skills in ASD and SLI. In the current study, we investigated Response Times (RTs) and Event Related Potentials (ERPs) during implicit learning on a Serial Reaction Time (SRT) task in a group of typically developing (TD) children (n = 17), a group of autistic children (n = 16), and a group of children with SLI (n = 13)...

Do individuals with autism have a developmental syntactic impairment, DLI (formerly known as SLI)? In this study we directly compared the performance of 18 individuals with Autism Spectrum Disorder (ASD) aged 9;0-18;0 years with that of 93 individuals with Syntactic-Developmental Language Impairment (SyDLI) aged 8;8-14;6 (and with 166 typically-developing children aged 5;2-18;1). We tested them using three syntactic tests assessing the comprehension and production of syntactic structures that are known to be sensitive to syntactic impairment: elicitation of subject and object relative clauses, reading and paraphrasing of object relatives, and repetition of complex syntactic structures including Wh questions, relative clauses, topicalized sentences, sentences with verb movement, sentences with A-movement, and embedded sentences...

INTRODUCTION: The finding of biological markers of specific language impairment would facilitate their detection and early intervention. In this sense, the 2D:4D finger ratio is considered an indirect indicator of prenatal exposure to testosterone. Previous studies have related it to linguistic competence and aggressive behaviour, and could be a candidate for a biological marker of language impairment. The aim was to compare the value of the 2D:4D ratio in children with Specific Language Impairment (SLI) with those of children with typical language development, as well as to establish to what extent this biological index correlates with the behaviour (linguistic, cognitive, social,...

BACKGROUND: It has been reported that the inhabitants of the Chilean Robinson Crusoe Island have an increased frequency of specific language impairment (SLI) or developmental language disorder (DLD). AIMS: To explore the familial aggregation of DLD in this community. METHODS & PROCEDURES: We assessed the frequency of DLD amongst colonial children between the ages of 3 and 8;11 years (50 individuals from 45 nuclear families). Familial aggregation rates of language disorder were calculated by assessing all available first-degree relatives (n = 107, 77 parents, 25 siblings, five half-siblings) of the probands...

Purpose: Specific language impairment (SLI) affects many children, but its symptomatology is still being characterized. An emerging view, which challenges the notion that SLI is specific to language, is that SLI may actually reflect a domain-general deficit in procedural learning. We explored an extension of this hypothesis that a core deficit in SLI involves a domain-general problem in planning. Method: We used a dowel-transport task to study the extent to which 13 children with SLI and 14 typically developing (TD) controls (ages over both groups between 8;10 [years;months] and 12;11) would adopt initially awkward grasps that ensured comfortable final grasps when reaching out to move a dowel from 1 position to another (the end-state comfort effect)...

Near-infrared photoimmunotherapy (NIR-PIT), a promising cancer therapy utilizing an antibody-photoabsorber conjugate (APC) and NIR light, which induces rapid necrotic cell death only in APC-bound cells. Effective NIR-PIT in mouse models has been achieved using superficial light illumination (SLI) with light emitting diodes (LEDs) or lasers, but in the clinical setting, fiber optic diffusers have been employed to deliver light to deeper tumors. However, the performance of NIR light in tissue delivered by fiber optic diffusers is poorly understood...

The proper course of speech development heavily influences the cognitive and personal development of children. It is a condition for achieving preschool and school successes - it facilitates socializing and expressing feelings and needs. Impairment of language and its development in children represents a major diagnostic and therapeutic challenge for physicians and therapists. Early diagnosis of coexisting deficits and starting the therapy influence the therapeutic success. One of the basic diagnostic tests for children suffering from specific language impairment (SLI) is audiometry, thus far referred to as a hearing test...

Purpose: Children with specific language impairment (SLI) show particular deficits in the generation of sequenced action: the quintessential procedural task. Practiced imitation of a sequence may become rote and require reduced procedural memory. This study explored whether speech motor deficits in children with SLI occur generally or only in conditions of high linguistic load, whether speech motor deficits diminish with practice, and whether it is beneficial to incorporate conditions of high load to understand speech production...

Purpose: Previous behavioral studies have found deficits in lexical-semantic abilities in children with specific language impairment (SLI), including reduced depth and breadth of word knowledge. This study explored the neural correlates of early emerging familiar word processing in preschoolers with SLI and typical development. Method: Fifteen preschoolers with typical development and 15 preschoolers with SLI were presented with pictures followed after a brief delay by an auditory label that did or did not match...

Purpose: The aim of this study was to investigate whether dual language experience affects procedural learning ability in typically developing children and in children with specific language impairment (SLI). Method: We examined procedural learning in monolingual and bilingual school-aged children (ages 8-12 years) with and without SLI. The typically developing children (35 monolinguals, 24 bilinguals) and the children with SLI (17 monolinguals, 10 bilinguals) completed a serial reaction time task...

Purpose: Bilinguals tend to produce cognates (e.g., telephone in English and teléfono in Spanish) more accurately than they produce noncognates (table/mesa). We tested whether the same holds for bilingual children with specific language impairment (SLI). Method: Participants included Spanish-English bilingual children (aged 5;0 to 9;11 [years;months]), 25 with SLI and 92 without, who had comparable language experience. Cognate and noncognate items were taken from English and Spanish versions of the Expressive One-Word Picture Vocabulary Test (Brownell, 2000, 2001)...

PURPOSE: This paper examines whether bilingual children with Specific Language Impairment (SLI) showed limited comprehension of Direct Object (DO) pronoun sentences and/or morphosyntactic priming compared to children with Typical Language Development (TLD) and adults. We analyzed the relation of these morphosyntactic processes to other psycholinguistic abilities, according to the MUC (Memory-Unification-Control) model. METHOD: Ten bilingual native Spanish-speaking children with SLI (8;3-10;6) and 10 age-matched children with TLD (7;6-10;10) received a psycholinguistic evaluation in Spanish-English...

Children with specific language impairment (SLI) often show considerable reading difficulties. Research has revealed two primary reading profiles among children with SLI: (a) one of poor word reading and decoding skills and associated reading comprehension difficulties, and (b) one involving relatively strong word reading skills but poor comprehension. This article reviews studies characterizing these two subtypes of SLI, discusses their current clinical implications, and suggests important directions for future study...

This study investigated the use of the Spanish subjunctive in bilingual children with and without specific language impairments (SLI). Using an elicited production task, we examined: (1) the potential of the subjunctive as a grammatical marker of SLI in Spanish-English bilingual children, (2) the extent to which degree of bilingualism affects performance, and (3) the specific patterns of errors across groups. The participants in this study were 16 children with SLI and 16 typically developing children (TD) matched on age, English language proficiency, and mother's education level...

BACKGROUND: Perception of speech rhythm requires the auditory system to track temporal envelope fluctuations, which carry syllabic and stress information. Reduced sensitivity to rhythmic acoustic cues has been evidenced in children with Specific Language Impairment (SLI), impeding syllabic parsing and speech decoding. Our study investigated whether these children experience specific difficulties processing fast rate speech as compared with typically developing (TD) children. METHOD: Sixteen French children with SLI (8-13 years old) with mainly expressive phonological disorders and with preserved comprehension and 16 age-matched TD children performed a judgment task on sentences produced 1) at normal rate, 2) at fast rate or 3) time-compressed...

BACKGROUND AND AIMS: We assumed that hand-held Doppler ultrasound (DUS) at rest was insufficient to assess the severity of peripheral artery disease (PAD). Toe pressure and transcutaneous tissue oxygen pressure were studied to prove whether these could identify more patients with severe lower limb ischemia; exercise was applied to provoke ischemia. METHODS: 120 patients with PAD and 30 volunteers without PAD were recruited. DUS, transcutaneous tissue oxygen pressure (tcpO2 ) and toe pressure measurements were performed at rest and after exercise...

Purpose: Name writing is one aspect of emergent writing that has been used to understand emergent literacy development. Name-writing skills and the relationship of name writing to other emergent literacy skills have not been studied extensively in children with specific language impairment (SLI). Children with SLI consistently demonstrate delays in phonological awareness (PA), alphabet knowledge (AK), print awareness, and emergent writing. The purpose of this study was to examine the contributions of PA, AK, and letter writing to name writing in children with SLI and typically developing (TD) children...

BACKGROUND: Grammatical morphology has been shown to be problematic for children with specific language impairment (SLI) or developmental language disorder (DLD). Most research on this topic comes from widely spoken languages, such as English. Despite Welsh being the most extensively spoken indigenous in the UK after English, and Wales being the only official bilingual country in the UK, our knowledge about the morphosyntactic areas of Welsh that may pose problems for Welsh-speaking children with SLI is limited...
