The four study groups included: 1. FAS/Partial FAS; 2. Static Encephalopathy/Alcohol Exposed (SE/AE); 3. Neurobehavioral Disorder/Alcohol Exposed (ND/AE); and 4. healthy peers with no prenatal alcohol exposure. fMRI outcomes are reported here. The neuropsychological/psychiatric, MRI, and MRS outcomes are reported separately. fMRI was used to assess activation in seven brain regions during performance of N-back working memory tasks. Children across the full spectrum of FASD exhibited significant working memory deficits and altered activation patterns in brain regions that are known to be involved in working memory. These results demonstrate the potential research and diagnostic value of this non-invasive MR tool in the field of FASD.

Movement perception and movement production in Asperger's Syndrome / Kelly J. PRICE in Research in Autism Spectrum Disorders, 6-1 (January-March 2012)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-1 (January-March 2012) . - p.391-398 Titre : Movement perception and movement production in Asperger's Syndrome Type de document : texte imprimé Auteurs : Kelly J. PRICE, Auteur ; Maggie SHIFFRAR, Auteur ; Kimberly A. KERNS, Auteur Année de publication : 2012 Article en page(s) : p.391-398 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD)  Asperger's Syndrome (AS)  Motor skills  Motion perception  Biological motion Index. décimale : PER Périodiques Résumé : To determine whether motor difficulties documented in Asperger's Syndrome (AS) are related to compromised visual abilities, this study examined perception and movement in response to dynamic visual environments. Fourteen males with AS and 16 controls aged 7–23 completed measures of motor skills, postural response to optic flow, and visual sensitivity to static form and coherent motion in random dot kinematograms and point-light walkers. No group differences were found in sensitivity to static form or coherent motion. However, significant group differences were found in visual sensitivity to human movement and postural responsivity to optic flow, which both correlated with motor skills. This may suggest difficulties in perception and production of movement and dysfunctional perceptual-motor linkages in AS.

Timing deficits are implicated in motor dysfunction in Asperger's Syndrome / Kelly J. PRICE in Research in Autism Spectrum Disorders, 6-2 (April-June 2012)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-2 (April-June 2012) . - p.857-860 Titre : Timing deficits are implicated in motor dysfunction in Asperger's Syndrome Type de document : texte imprimé Auteurs : Kelly J. PRICE, Auteur ; Dorothy EDGELL, Auteur ; Kimberly A. KERNS, Auteur Année de publication : 2012 Article en page(s) : p.857-860 Langues : Anglais (eng) Mots-clés : Asperger  Autism  Motor  Movement  Timing  Perception Index. décimale : PER Périodiques Résumé : This study addressed what role movement timing irregularities have in producing the motor deficits documented in Asperger's Syndrome (AS). Participants included males with AS (n = 14) and without (n = 16), matched by age (7–23 years) and with no significant IQ differences. They completed measures of timing perception (comparisons of tempo of tones) and production (rhythmic finger tapping), and general motor skills (Dean–Woodcock Neuropsychological Battery motor tests). No central timing difficulties were noted, but the AS group showed more irregularity in motor implementation (with a large effect size), and this irregularity correlated with general motor skills.
