Goodwin, Anthony; Matthews, Nicole L.; Smith, Christopher J. – Autism: The International Journal of Research and Practice, 2019
Despite efforts to detect autism spectrum disorder during toddlerhood, many children with autism spectrum disorder remain undiagnosed until school age. To identify characteristics of children whose autism spectrum disorder might not be diagnosed during toddlerhood, this study used archived Autism Diagnostic Interview-Revised records to examine the…

Kang, Veronica Y.; Kim, Sunyoung – Journal of Early Intervention, 2023
Teaching vocabularies to young children is critical as vocabulary is related to long-term language, literacy, and academic skills. The current study used a multiple probe design to examine the effects of enhanced milieu teaching with book reading on the use of word approximations in four 2- to 4-year-old females with language delay. The first…

Wang, Jiaxing; Ding, Gang; Li, Ying; Hua, Ning; Wei, Nan; Qi, Xiaoli; Ning, Yuxian; Zhang, Ying; Li, Xue; Li, Jing; Song, Linlin; Qian, Xuehan – Journal of Autism and Developmental Disorders, 2018
Amblyopia risk factors in children with autism spectrum disorders (ASD) are usually hard to detect in early childhood due to poor cooperation and has not been reported in the Chinese population. We screened 168 Chinese children with ASD, aged between 3 and 8 years, and 264 age-matched neurotypical children with Spot photoscreener and basic…

Davidovitch, Michael; Stein, Nataly; Koren, Gideon; Friedman, Bat Chen – Journal of Autism and Developmental Disorders, 2018
This study was designed to track the developmental trajectory, during the first 24 months of life, of 335 low-risk infants later diagnosed with Autism Spectrum Disorder and identify early deviations observed in routine Well Care checkups. We compared their achievements to typically developing children and to children later diagnosed with…

Soke, Gnakub N.; Maenner, M. J.; Christensen, D.; Kurzius-Spencer, M.; Schieve, L. A. – Journal of Autism and Developmental Disorders, 2017
We compared early-diagnosed autism spectrum disorder (ASD) (defined as diagnosis by age 4 years) between the 2002 and 2006 birth cohorts, in five sites of the Autism and Developmental Disabilities Monitoring Network. In the 2002 cohort, the prevalence/1000 of early-diagnosed ASD was half the 8-year-old prevalence (7.2 vs. 14.7, prevalence ratio…

Clark, Megan Louise Erin; Vinen, Zoe; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2018
Early diagnosis of Autism Spectrum Disorder is considered best practice, increasing access to early intervention. Yet, many children are diagnosed after 3-years. The current study investigated the school age outcomes of children who received an early and later diagnosis of ASD. The cognitive and behavioural outcomes of children diagnosed early (n…

Horvath, Sabrina; Rescorla, Leslie; Arunachalam, Sudha – Journal of Child Language, 2019
Children with language disorders have particular difficulty with verbs, but when this difficulty emerges is unknown. We examined syntactic (transitive, intransitive, ditransitive) and semantic (manner, result) features of two-year-olds' verb vocabularies, contrasting late talkers and typically developing children to look for early differences in…

There is growing evidence of a camouflaging effect among females with autism spectrum disorder (ASD), particularly among those without intellectual disability, which may affect performance on gold-standard diagnostic measures. This study utilized an age- and IQ-matched sample of school-aged youth (n = 228) diagnosed with ASD to assess sex…

Miller, Daniel C.; Maricle, Denise E.; Jones, Alicia M. – Learning Disabilities: A Multidisciplinary Journal, 2016
Processing Strengths and Weaknesses (PSW) models have been proposed as a method for identifying specific learning disabilities. Three PSW models were examined for their ability to predict expert identified specific learning disabilities cases. The Dual Discrepancy/Consistency Model (DD/C; Flanagan, Ortiz, & Alfonso, 2013) as operationalized by…

Tong, Xiuhong; Tong, Xiuli; King Yiu, Fung – Journal of Learning Disabilities, 2018
Increasing evidence suggests that children with developmental dyslexia exhibit a deficit not only at the segmental level of phonological processing but also, by extension, at the suprasegmental level. However, it remains unclear whether such a suprasegmental phonological processing deficit is due to a difficulty in processing acoustic cues of…

Jerger, Sara; Thorne, John C. – Language, Speech, and Hearing Services in Schools, 2016
Purpose: This research attempted to replicate Hoffman's 2009 finding that the proportion of narrative utterances with semantic or syntactic errors (i.e., = 14% "restricted utterances") can differentiate school-age children with typical development from those with language impairment with a sensitivity of 83% and specificity of 88%.…

Bell, Sherry Mee; Taylor, Emily P.; McCallum, R. Steve; Coles, Jeremy T.; Hays, Elizabeth – Journal for the Education of the Gifted, 2015
From a sample of 1,242 third graders, prospective twice-exceptional students were selected using reading and math curriculum-based measures (CBMs), routinely used in Response to Intervention (RtI). These prospective twice-exceptional students were compared with non-twice-exceptional peers with similar strengths in either math or reading on CBMs…

Tattersall, Patricia J.; Nelson, Nickola Wolf; Tyler, Ann A. – Communication Disorders Quarterly, 2015
Two sets of nonwords (with and without true morphemes) were compared for their ability to differentiate students in Grades 1 through 12 with and without language impairment (36 each; N = 72) on a nonword repetition task. Results indicated that either nonword type could contribute to differential diagnosis.

Winstanley, Maxine; Webb, Roger T.; Conti-Ramsden, Gina – International Journal of Language & Communication Disorders, 2018
Background: There is now substantial literature demonstrating that a disproportionate number of young people who come into contact with youth justice services evidence unidentified language difficulties. These young people, therefore, have received little or no professional input in this area. Conversely, there is a dearth of research pertaining…

Cavalli, Eddy; Colé, Pascale; Leloup, Gilles; Poracchia-George, Florence; Sprenger-Charolles, Liliane; El Ahmadi, Abdessadek – Journal of Learning Disabilities, 2018
Developmental dyslexia is a lifelong impairment affecting 5% to 10% of the population. In French-speaking countries, although a number of standardized tests for dyslexia in children are available, tools suitable to screen for dyslexia in adults are lacking. In this study, we administered the "Alouette" reading test to a normative sample…
