We examined the influence of an antecedent communication intervention on challenging behavior for three students with developmental disorders. Students were taught to request tangible items that were identified as reinforcers for challenging behavior in a prior functional analysis. Individual participant multielement and reversal designs were used…

Johns, Adam; Homewood, Judi; Stevenson, Richard; Taylor, Alan – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
This study examined differences in implicit and explicit memory performance between people with Down syndrome (DS), their siblings, children matched on mental age, and university undergraduates, using olfactory stimuli. The DS and mental-age matched participants were also compared on two tasks of executive function. The data revealed implicit…

Hamed, Ragaa R.; Maharem, Tahany M.; Abdel-Meguid, Nagwa; Sabry, Gilane M.; Abdalla, Abdel-Monem; Guneidy, Rasha A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Down syndrome (DS) is the phenotypic manifestation of trisomy 21. Our study was concerned with the characterization and purification of glutathione S-transferase enzyme (GST) from normal and Down syndrome (DS) erythrocytes to illustrate the difference in the role of this enzyme in the cell. Glutathione S-transferase and glutathione (GSH) was…

van der Meer, Larah; Kagohara, Debora; Achmadi, Donna; O'Reilly, Mark F.; Lancioni, Giulio E.; Sutherland, Dean; Sigafoos, Jeff – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
We compared speed of acquisition and preference for using a speech-generating device (SGD) versus manual signing (MS) as augmentative and alternative communication (AAC) options. Four children with developmental disabilities (DD), aged 5-10 years, were taught to request preferred objects using an iPod[R]-based SGD and MS. Intervention was…

Channell, Marie Moore; Loveall, Susan J.; Conners, Frances A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
Reading-related skills of youth with intellectual disability (ID) were compared with those of typically developing (TD) children of similar verbal ability level. The group with ID scored lower than the TD group on word recognition and phonological decoding, but similarly on orthographic processing and rapid automatized naming (RAN). Further,…

Gonzalez-Aguero, Alejandro; Ara, Ignacio; Moreno, Luis A.; Vicente-Rodriguez, German; Casajus, Jose A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The present study aimed at comparing fat and lean masses between children and adolescents with and without Down syndrome (DS) and evaluating the presence of sexual dimorphism. Total and regional fat and lean masses were assessed by dual energy X-ray absorptiometry (DXA) and the percentage of body fat (%BF) by air-displacement plethysmography (ADP)…

To determine the accuracy of the published percentage body fat (%BF) prediction equations (Durnin et al., Johnston et al., Brook and Slaughter et al.) from skinfold thickness compared to air displacement plethysmography (ADP) in children and adolescents with Down syndrome (DS). Twenty-eight children and adolescents with DS (10-20 years old; 12…

Giuliani, Fabienne; Favrod, Jerome; Grasset, Francois; Schenk, Francoise – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Using head-mounted eye tracker material, we assessed spatial recognition abilities (e.g., reaction to object permutation, removal or replacement with a new object) in participants with intellectual disabilities. The "Intellectual Disabilities (ID)" group (n = 40) obtained a score totalling a 93.7% success rate, whereas the "Normal Control" group…

Derlich, Malgorzata; Krecisz, Krzysztof; Kuczynski, Michal – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
To elucidate the mechanisms responsible for deteriorated postural control in children with hearing deficit (CwHD), we measured center-of-pressure (COP) variability, mean velocity and entropy in bipedal quiet stance (feet together) with or without the concurrent cognitive task (reaction to visual stimulus) on hard or foam surface in 29 CwHD and a…

The purpose of this study was to analyze the alpha-amylase (sAA) and cortisol levels in children with Global developmental delay (GDD) before and after dental treatment and its association with the children's behavior during treatment. The morning salivary cortisol levels and activity of sAA of 33 children with GDD were evaluated before and after…

de Campos, Ana Carolina; Francisco, Kelly Regina; Savelsbergh, Geert J. P.; Rocha, Nelci Adriana Cicuto Ferreira – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Reaching and grasping skills have been described to emerge from a dynamic interaction between intrinsic and extrinsic factors. The purpose of the present study was to investigate the interaction between such an intrinsic factor, Down syndrome, and extrinsic factors, such as different object properties. Seven infants with Down syndrome and seven…

Galli, Manuela; Rigoldi, Chiara; Celletti, Claudia; Mainardi, Luca; Tenore, Nunzio; Albertini, Giorgio; Camerota, Filippo – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The goal of this work is to analyze postural control in Ehlers-Danlos syndrome (EDS) participants in time and frequency domain. This study considered a pathological group composed by 22 EDS participants performing a postural test consisting in maintaining standing position over a force platform for 30 s in two conditions: open eyes (OE) and closed…

Tenenbaum, Ariel; Chavkin, Maor; Wexler, Isaiah D.; Korem, Maya; Merrick, Joav – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Over the last decade a significant increase in the life expectancy of people with Down syndrome (DS) has been observed, which has caused a higher incidence of morbidity as they age. However, there is a lack of literature regarding morbidity and hospitalization of adults with DS. Analysis of 297 hospitalizations of 120 adults with DS aged 18-73…

The authors examine the reading profile in children with Down syndrome by comparing the nonword decoding skills in children with Down syndrome and typically developing children matched for word recognition level. Journal articles published before 04.05.2010 were identified by using the keyword Down* cross-referenced to "reading", "literacy",…

Rigoldi, Chiara; Galli, Manuela; Mainardi, Luca; Crivellini, Marcello; Albertini, Giorgio – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The goal of this work was to analyze postural control in Down syndrome (DS) participants considering three different groups composed by children, teenagers and adults with DS. An analysis of the centre of pressure (COP) displacement during standing position was therefore performed for the three groups of subjects. The obtained signal of COP was…
