Conson, Massimiliano; Siciliano, Mattia; Trojano, Luigi; Zoccolotti, Pierluigi; Zappullo, Isa; Baiano, Chiara; Caputo, Giovanni; Russo, Alessandro; Cecere, Roberta; Cecere, Roberta; Di Rosa, Alessandro; Esposito, Giovanna; Milo, Rosa; Polito, Francesco; Rauso, Barbara; Vela, Maria; Santangelo, Gabriella – Journal of Autism and Developmental Disorders, 2022
In two studies, we used the Gottschaldt's Hidden Figure Test (GHFT) for assessing figure disembedding ability in children aged 7-11. Study 1 demonstrated in a large sample of typically developing children that GHFT accuracy and time scores differed across age groups, without sex and socioeconomic differences. Thus, we provided normative data only…

Brief Report: An Exploration of Cognitive Flexibility of Autistic Adolescents with Low Intelligence Using the Wisconsin Card Sorting Task
Peer reviewed Peer reviewed
Direct linkDirect link
Lung, Stephanie Lock Man; Bertone, Armando – Journal of Autism and Developmental Disorders, 2023
Cognitive flexibility (CF) is the ability to shift between concepts or rules. Difficulty with CF is associated with autism (i.e., ASD) as it contributes to repetitive behaviours. However, little is known about CF skills of autistic adolescents with low intelligence. This study uses the Wisconsin Card Sorting Task (WCST) to assess the CF of 36…

Haigh, Sarah M.; Walsh, Jennifer A.; Mazefsky, Carla A.; Minshew, Nancy J.; Eack, Shaun M. – Journal of Autism and Developmental Disorders, 2018
Autism spectrum disorder (ASD) is characterized by a variety of social and non-social behavioral deficits. One potential mechanism that could unify this diverse profile of behaviors is slower processing speed. Seventy-six high-functioning adults with ASD were compared to 64 matched controls on standardized measures of processing speed.…

Brief Report: Cognitive Performance in Autism and Asperger's Syndrome: What Are the Differences?
Peer reviewed Peer reviewed
Direct linkDirect link
Taddei, Stefano; Contena, Bastianina – Journal of Autism and Developmental Disorders, 2013
Autism spectrum disorders include autistic and Asperger's Syndrome (AS), often studied in terms of executive functions (EF), with controversial results. Using Planning Attention Simultaneous Successive theory (PASS; Das et al. in "Assessment of cognitive processes: the PASS theory of intelligence." Allyn and Bacon, Boston, MA, 1994),…

Keary, Christopher J.; Minshew, Nancy J.; Bansal, Rahul; Goradia, Dhruman; Fedorov, Serguei; Keshavan, Matcheri S.; Hardan, Antonio Y. – Journal of Autism and Developmental Disorders, 2009
The corpus callosum has recently been considered as an index of interhemispheric connectivity. This study applied a novel volumetric method to examine the size of the corpus callosum in 32 individuals with autism and 34 age-, gender- and IQ-matched controls and to investigate the relationship between this structure and cognitive measures linked to…

Ozonoff, Sally; Cook, Ian; Coon, Hilary; Dawson, Geraldine; Joseph, Robert M.; Klin, Ami; McMahon, William M.; Minshew, Nancy; Munson, Jeffrey A. – Journal of Autism and Developmental Disorders, 2004
Recent structural and functional imaging work, as well as neuropathology and neuropsychology studies, provide strong empirical support for the involvement of frontal cortex in autism. The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a computer-administered set of neuropsychological tests developed to examine specific components…
