Direct linkSeager, Robert D. – American Biology Teacher, 2014
In learning genetics, many students misunderstand and misinterpret what "dominance" means. Understanding is easier if students realize that dominance is not a mechanism, but rather a consequence of underlying cellular processes. For example, metabolic pathways are often little affected by changes in enzyme concentration. This means that…

Creer, Sarah; Enderby, Pamela; Judge, Simon; John, Alex – International Journal of Language & Communication Disorders, 2016
Background: Commissioners and providers require information relating to the number of people requiring a service in order to ensure provision is appropriate and equitable for the population they serve. There is little epidemiological evidence available regarding the prevalence of people who could benefit from augmentative and alternative…

Reilly, Colin; Murtagh, Lelia; Senior, Joyce – Journal of Research in Special Educational Needs, 2016
Research suggests that genetic syndromes associated with intellectual disability often have specific cognitive and behavioural profiles. It has been suggested that educational approaches need to reflect these profiles. Parents (n = 381) and teachers (n = 204) of children with one of four syndromes, fragile X syndrome, Prader-Willi syndrome,…

Alexeeff, Stacey E.; Yau, Vincent; Qian, Yinge; Davignon, Meghan; Lynch, Frances; Crawford, Phillip; Davis, Robert; Croen, Lisa A. – Journal of Autism and Developmental Disorders, 2017
This study examines medical conditions diagnosed prior to the diagnosis of autism spectrum disorder (ASD). Using a matched case control design with 3911 ASD cases and 38,609 controls, we found that 38 out of 79 medical conditions were associated with increased ASD risk. Developmental delay, mental health, and neurology conditions had the strongest…

Thompson, Paul A.; Hulme, Charles; Nash, Hannah M.; Gooch, Debbie; Hayiou-Thomas, Emma; Snowling, Margaret J. – Journal of Child Psychology and Psychiatry, 2015
Background: Causal theories of dyslexia suggest that it is a heritable disorder, which is the outcome of multiple risk factors. However, whether early screening for dyslexia is viable is not yet known. Methods: The study followed children at high risk of dyslexia from preschool through the early primary years assessing them from age 3 years and 6…

Chevalère, Johann; Postal, Virginie; Jauregui, Joseba; Copet, Pierre; Laurier, Virginie; Thuilleaux, Denise – American Journal on Intellectual and Developmental Disabilities, 2015
The aim of this study was to support the growing evidence suggesting that Prader-Willi Syndrome (PWS) might present with an impairment of executive functions (EFs) and to investigate whether this impairment is specific to patients with PWS or due to their intellectual disability (ID). Six tasks were administered to assess EFs (inhibition,…

Brazendale, Allison; Adlof, Suzanne; Klusek, Jessica; Roberts, Jane – EBP Briefs (Evidence-based Practice Briefs), 2015
Clinical Question: Would a child with fragile X syndrome benefit more from phonemic awareness and phonics instruction or whole-word training to increase reading skills? Method: Systematic review. Study Sources: PsycINFO. Search Terms: fragile X OR Down syndrome OR cognitive impairment OR cognitive deficit OR cognitive disability OR intellectual…

Giersch, Anne; Glaser, Bronwyn; Pasca, Catherine; Chabloz, Mélanie; Debbané, Martin; Eliez, Stephan – American Journal on Intellectual and Developmental Disabilities, 2014
Individuals with 22q11.2 deletion syndrome (22q11.2DS) are impaired at exploring visual information in space; however, not much is known about visual form discrimination in the syndrome. Thirty-five individuals with 22q11.2DS and 41 controls completed a form discrimination task with global forms made up of local elements. Affected individuals…

Sugarman, Michael A.; Jacobs, Dennis R.; Paulson, Daniel; Tomlinson, M. Michele; Lichtenberg, Peter A. – Journal of Intellectual & Developmental Disability, 2014
Background: The goal of the current study was to determine if the Dementia Rating Scale-2 (DRS-2) is an appropriate tool for evaluating cognitive abilities in adults with Prader-Willi syndrome (PWS). The DRS-2 is a screening measure previously utilised in low-functioning populations with and without dementia, including individuals with…

Waite, Jane; Beck, Sarah R.; Heald, Mary; Powis, Laurie; Oliver, Chris – Journal of Autism and Developmental Disorders, 2016
Working memory (WM) impairments might amplify behavioural difference in genetic syndromes. Murine models of Rubinstein-Taybi syndrome (RTS) evidence memory impairments but there is limited research on memory in RTS. Individuals with RTS and typically developing children completed WM tasks, with participants with RTS completing an IQ assessment and…

Davis, Beth; Murphy, M. Shaun – Teachers and Teaching: Theory and Practice, 2016
This paper inquires into the experiences of an early childhood educator named Claire who taught a young girl with a chronic illness at East Willows Elementary School, a western Canadian elementary school. Using narrative inquiry as the methodology, Claire's experiences in her curriculum making alongside Madeline a young girl with Turner syndrome…

The 16p11.2 duplication (BP4-BP5) is associated with Autism Spectrum Disorder (ASD), although significant heterogeneity exists. Quantitative ASD, behavioral and neuropsychological measures and DSM-IV diagnoses in child and adult carriers were compared with familial non-carrier controls, and to published results from deletion carriers. The 16p11.2…

Weisman, O.; Feldman, R.; Burg-Malki, M.; Keren, M.; Geva, R.; Diesendruck, G.; Gothelf, D. – Journal of Intellectual Disability Research, 2017
Background: Numerous studies have assessed the socio-cognitive profile in Williams syndrome (WS) and, independently, in 22q11.2 deletion syndrome (22q11.2DS). Yet, a cross-syndrome comparison of these abilities between individuals with these two syndromes with known social deficits has not been conducted. Methods: Eighty-two children participated…

Van Den Heuvel, Ellen; Manders, Eric; Swillen, Ann; Zink, Inge – Journal of Intellectual & Developmental Disability, 2017
Background: Children with 22q11.2 deletion syndrome (22q11.2DS) are reported to have socio-communicative impairments. Although many of these children are diagnosed with intellectual disability (ID) and/or autism spectrum disorder (ASD), these populations are seldom used as control groups. Hence, information regarding syndrome-specific…

Thurman, Angela John; McDuffie, Andrea; Kover, Sara T.; Hagerman, Randi; Channell, Marie Moore; Mastergeorge, Ann; Abbeduto, Leonard – Journal of Autism and Developmental Disorders, 2015
The present study evaluated the ability of males with fragile X syndrome (FXS), nonsyndromic autism spectrum disorder (ASD), or typical development to learn new words by using as a cue to the intended referent an emotional reaction indicating a successful (excitement) or unsuccessful (disappointment) search for a novel object. Performance for all…
