Eye-Hand Coordination in Children with High Functioning Autism and Asperger’s Disorder Using a Gap-Overlap Paradigm / Alessandro CRIPPA in Journal of Autism and Developmental Disorders, 43-4 (April 2013)

The eye-hand correlation was measured by putting fixation latencies in relation with pointing and key pressing responses in visual detection tasks where a gap-overlap paradigm was used and compared to fixation latencies in absence of manual response. ASD patients showed less efficient eye-hand coordination, which was particularly evident when pointing towards a target was being fixated. The data of normally developing participants confirmed that manual gap effects are more likely for more complex hand movements. An important discrepancy was discovered in participants with ASD: beside normal eye gap effects, they showed no concurrent hand gap effects when pointing to targets. This result has been interpreted as a further sign of inefficient eye-hand coordination in this patient population.

Use of Machine Learning to Identify Children with Autism and Their Motor Abnormalities / Alessandro CRIPPA in Journal of Autism and Developmental Disorders, 45-7 (July 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-7 (July 2015) . - p.2146-2156 Titre : Use of Machine Learning to Identify Children with Autism and Their Motor Abnormalities Type de document : Texte imprimé et/ou numérique Auteurs : Alessandro CRIPPA, Auteur ; Christian SALVATORE, Auteur ; Paolo PEREGO, Auteur ; Sara FORTI, Auteur ; Maria NOBILE, Auteur ; Massimo MOLTENI, Auteur ; Isabella CASTIGLIONI, Auteur Année de publication : 2015 Article en page(s) : p.2146-2156 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Kinematics  Classification  Machine learning  Support vector machines Index. décimale : PER Périodiques Résumé : In the present work, we have undertaken a proof-of-concept study to determine whether a simple upper-limb movement could be useful to accurately classify low-functioning children with autism spectrum disorder (ASD) aged 2–4. To answer this question, we developed a supervised machine-learning method to correctly discriminate 15 preschool children with ASD from 15 typically developing children by means of kinematic analysis of a simple reach-to-drop task. Our method reached a maximum classification accuracy of 96.7 % with seven features related to the goal-oriented part of the movement. These preliminary findings offer insight into a possible motor signature of ASD that may be potentially useful in identifying a well-defined subset of patients, reducing the clinical heterogeneity within the broad behavioral phenotype.
