Atypical emotional anticipation in high-functioning autism / Letizia PALUMBO in Molecular Autism, (August 2015)  

Public ISBD [article]  inMolecular Autism > (August 2015) . - p.1-17 Titre : Atypical emotional anticipation in high-functioning autism Type de document : Texte imprimé et/ou numérique Auteurs : Letizia PALUMBO, Auteur ; Hollie G. BURNETT, Auteur ; Tjeerd JELLEMA, Auteur Article en page(s) : p.1-17 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Understanding and anticipating others’ mental or emotional states relies on the processing of social cues, such as dynamic facial expressions. Individuals with high-functioning autism (HFA) may process these cues differently from individuals with typical development (TD) and purportedly use a ‘mechanistic’ rather than a ‘mentalistic’ approach, involving rule- and contingency-based interpretations of the stimuli. The study primarily aimed at examining whether the judgments of facial expressions made by individuals with TD and HFA would be similarly affected by the immediately preceding dynamic perceptual history of that face. A second aim was to explore possible differences in the mechanisms underpinning the perceptual judgments in the two groups.

Symmetry Detection in Autistic Adults Benefits from Local Processing in a Contour Integration Task / Sabrina SUBRI in Journal of Autism and Developmental Disorders, 54-10 (October 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-10 (October 2024) . - p.3684-3696 Titre : Symmetry Detection in Autistic Adults Benefits from Local Processing in a Contour Integration Task Type de document : Texte imprimé et/ou numérique Auteurs : Sabrina SUBRI, Auteur ; Letizia PALUMBO, Auteur ; Emma GOWEN, Auteur Article en page(s) : p.3684-3696 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Symmetry studies in autism are inconclusive possibly due to different types of stimuli used which depend on either local or global cues. Therefore, this study compared symmetry detection between 20 autistic and 18 non-autistic adults matched on age, IQ, gender and handedness, using contour integration tasks containing open and closed contours that rely more on local or global processing respectively. Results showed that the autistic group performed equally well with both stimuli and outperformed the non-autistic group only for the open contours, possibly due to a different strategy used in detecting symmetry. However, there were no group differences for the closed contour. Results explain discrepant findings in previous symmetry studies suggesting that symmetry tasks that favour a local strategy may be advantageous for autistic individuals. Implications of the findings towards understanding visual sensory issues in this group are discussed.
