Emotional Resonance Deficits in Autistic Children / Alessandro GRECUCCI in Journal of Autism and Developmental Disorders, 43-3 (March 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-3 (March 2013) . - p.616-628 Titre : Emotional Resonance Deficits in Autistic Children Type de document : Texte imprimé et/ou numérique Auteurs : Alessandro GRECUCCI, Auteur ; Paolo BRAMBILLA, Auteur ; Roma SIUGZDAITE, Auteur ; Danielle LONDERO, Auteur ; Franco FABBRO, Auteur ; Raffaella Ida RUMIATI, Auteur Article en page(s) : p.616-628 Langues : Anglais (eng) Mots-clés : Imitation  Action resonance  Empathy  Emotions  Mirror neurons Index. décimale : PER Périodiques Résumé : According to some theories imitation, defined as an action resonance mechanism, is deficient in autism. In contrast, other theories (e.g., the “top down control of imitation” hypothesis) state that the problem is not in imitation per se but in the way social cues modulate imitative responses. In this study, 15 high-functioning children with autism and 15 matched controls were tested for their ability to imitate finger movements preceded by neutral and emotional facial expressions (primes) in a stimulus–response compatibility task. Hand movements performed after neutral expressions did not differ between the two groups (i.e., they both showed a normal imitative tendency). However, hand movements performed after emotional expressions significantly differed between the two populations, with controls, but not autistic spectrum disorder (ASD), showing enhanced imitation in the emotional condition. This study supports the view that, in ASD, imitation abilities are spared but they are not modulated according to the emotional and social context.

Navigation and exploration of an urban virtual environment by children with autism spectrum disorder compared to children with typical development / Livia FORNASARI in Research in Autism Spectrum Disorders, 7-8 (August 2013)

For this purpose, virtual environments (VEs), i.e., simulations of the real world based on 3D computer graphics, can offer a safe learning environment for them. This study analyzed navigation and exploration of an urban VE by children with ASD in comparison to children with a typical development. Sixteen children with ASD and 16 matched control ones were involved. After an initial training phase, children carried out two tasks: the first one was navigating in an unfamiliar urban environment which they could freely explore; the second one was navigating in the same environment but with the goal of finding specific target objects, as in a treasure hunt. In the first task, children with ASD spent significantly less time in active exploration and explored fewer zones than controls. No differences were found between the two groups in the second task. Our data indicate that, when freely exploring an unfamiliar VE, children with ASD explore less the environment compared to the control ones. By repeating the exploration with a game-like goal, no differences were found instead. Neuropsychological and motivational aspects should be considered in order to explain these findings.

Neuropsychological Profile in High Functioning Autism Spectrum Disorders / Antonio NARZISI in Journal of Autism and Developmental Disorders, 43-8 (August 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-8 (August 2013) . - p.1895-1909 Titre : Neuropsychological Profile in High Functioning Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Antonio NARZISI, Auteur ; Filippo MURATORI, Auteur ; Sara CALDERONI, Auteur ; Franco FABBRO, Auteur ; Cosimo URGESI, Auteur Article en page(s) : p.1895-1909 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  NEPSY  Neuropsychology  Theory of Mind Index. décimale : PER Périodiques Résumé : A comprehensive investigation of the neuropsychological strengths and weaknesses of children with autism may help to better describe their cognitive abilities and to design appropriate interventions. To this end we compared the NEPSY-II profiles of 22 children with high-functioning autism spectrum disorders (HFASD) with those of 44 healthy control (HC) children 2:1 matched by gender, age, race and education. Results showed that only Visuospatial Processing was relatively spared in HFASD, while deficits were observed in Attention and Executive Functions, Language, Learning and Memory, and Sensorimotor Processing. Theory of Mind difficulties were observed in verbal tasks but not in the understanding of emotional contexts, suggesting that appropriate contextual cues might help emotion understanding in HFASD children. These widespread neuropsychological impairments reflect alterations in multiple cognitive domains in HFASD.
