Keith, Jessica M.; Jamieson, Jeremy P.; Bennetto, Loisa – Journal of Autism and Developmental Disorders, 2019
This study examined the impact of noise on cognitive performance in autism spectrum disorder (ASD), while concurrently measuring sympathetic responses. Adolescents with and without ASD completed visually presented span tasks in a 2 × 2 experimental manipulation of noise (quiet vs. 75 dB gated broadband noise) and task difficulty (easier vs.…

Guy, Jacalyn; Mottron, Laurent; Berthiaume, Claude; Bertone, Armando – Journal of Autism and Developmental Disorders, 2019
Individuals with autism spectrum disorder (ASD) demonstrate superior performances on visuo-spatial tasks emphasizing local information processing; however, findings from studies involving hierarchical stimuli are inconsistent. Wide age ranges and group means complicate their interpretability. Children and adolescents with and without ASD completed…

Ciaramelli, Elisa; Spoglianti, Silvia; Bertossi, Elena; Generali, Nadia; Telarucci, Francesca; Tancredi, Raffaella; Muratori, Filippo; Igliozzi, Roberta – Journal of Autism and Developmental Disorders, 2018
We studied episodic memory and future thinking for self-relevant and other-relevant events at different levels of retrieval support, theory of mind, and delay discounting in ASD children and adolescents (ASDs). Compared to typically developing controls, ASDs produced fewer internal (episodic) but a similar number of external (semantic) details…

Luckhardt, Christina; Kröger, Anne; Cholemkery, Hannah; Bender, Stephan; Freitag, Christine M. – Journal of Autism and Developmental Disorders, 2017
The underlying neural mechanisms of implicit and explicit facial emotion recognition (FER) were studied in children and adolescents with autism spectrum disorder (ASD) compared to matched typically developing controls (TDC). EEG was obtained from N = 21 ASD and N = 16 TDC. Task performance, visual (P100, N170) and cognitive (late positive…

Vanmarcke, Steven; Noens, Ilse; Steyaert, Jean; Wagemans, Johan – Journal of Autism and Developmental Disorders, 2017
While most typically developing (TD) participants have a coarse-to-fine processing style, people with autism spectrum disorder (ASD) seem to be less globally and more locally biased when processing visual information. The stimulus-specific spatial frequency content might be directly relevant to determine this temporal hierarchy of visual…

Rosa, Mireia; Puig, Olga; Lázaro, Luisa; Vallés, Virginia; Lera, Sara; Sánchez-Gistau, Vanesa; Calvo, Rosa – Journal of Autism and Developmental Disorders, 2017
Despite evidence supporting the presence of cognitive deficits in children and adolescents with high-functioning autism spectrum disorder (HF-ASD), the nature of these deficits and their clinical and adaptive correlates remain unclear. Moreover, there are few cognitive studies of ASD siblings as a high risk population. We compared 50 children and…

Lehnhardt, Fritz-Georg; Falter, Christine Michaela; Gawronski, Astrid; Pfeiffer, Kathleen; Tepest, Ralf; Franklin, Jeremy; Vogeley, Kai – Journal of Autism and Developmental Disorders, 2016
Females with high-functioning ASD are known to camouflage their autistic symptoms better than their male counterparts, making them prone to being under-ascertained and delayed in diagnostic assessment. Thus far the underlying cognitive processes that enable such successful socio-communicative adaptation are not well understood. The current results…

Hollocks, Matthew J.; Pickles, Andrew; Howlin, Patricia; Simonoff, Emily – Journal of Autism and Developmental Disorders, 2016
Young people with autism spectrum disorder (ASD) have a high prevalence (~40 %) of anxiety disorders compared to their non-ASD peers. It is unclear whether cognitive and biological processes associated with anxiety in ASD are analogous to anxiety in typically developing (TD) populations. In this study 55 boys with ASD (34 with a co-occurring…

Kovarski, K.; Thillay, A.; Houy-Durand, E.; Roux, S.; Bidet-Caulet, A.; Bonnet-Brilhault, F.; Batty, M. – Journal of Autism and Developmental Disorders, 2016
Autism spectrum disorder (ASD) is characterized by atypical visual perception both in the social and nonsocial domain. In order to measure a reliable visual response, visual evoked potentials were recorded during a passive pattern-reversal stimulation in adolescents and adults with and without ASD. While the present results show the same…

Neuhaus, Emily; Jones, Emily J. H.; Barnes, Karen; Sterling, Lindsey; Estes, Annette; Munson, Jeff; Dawson, Geraldine; Webb, Sara J. – Journal of Autism and Developmental Disorders, 2016
Both autism spectrum (ASD) and anxiety disorders are associated with atypical neural and attentional responses to emotional faces, differing in affective face processing from typically developing peers. Within a longitudinal study of children with ASD (23 male, 3 female), we hypothesized that early ERPs to emotional faces would predict concurrent…

Khemka, Ishita; Hickson, Linda; Mallory, Sarah B. – Journal of Autism and Developmental Disorders, 2016
This study was designed to assess the impact of a decision-making curriculum (PEER-DM) on the social peer relationship knowledge and self-protective decision-making skills of adolescents with disabilities in hypothetical situations involving negative peer pressure. A randomized design was used to assign students with disabilities from…

Vogan, V. M.; Morgan, B. R.; Leung, R. C.; Anagnostou, E.; Doyle-Thomas, K.; Taylor, M. J. – Journal of Autism and Developmental Disorders, 2016
Diffusion tensor imaging studies show white matter (WM) abnormalities in children with autism spectrum disorder (ASD). However, investigations are often limited by small samples, particularly problematic given the heterogeneity of ASD. We explored WM using DTI in a large sample of 130 children and adolescents (7-15 years) with and without ASD,…

Gökçen, Elif; Frederickson, Norah; Petrides, K. V. – Journal of Autism and Developmental Disorders, 2016
Autism spectrum disorder (ASD) is characterised by profound difficulties in empathic processing and executive control. Whilst the links between these processes have been frequently investigated in populations with autism, few studies have examined them at the subclinical level. In addition, the contribution of alexithymia, a trait characterised by…

Clawson, Ann; Clayson, Peter E.; South, Mikle; Bigler, Erin D.; Larson, Michael J. – Journal of Autism and Developmental Disorders, 2015
Little is known about the functional impact of putative deficits in white-matter connectivity across the corpus callosum (CC) in individuals with autism spectrum disorders (ASDs). We utilized the temporal sensitivity of event-related potentials to examine the interhemispheric transfer time (IHTT) of basic visual information across the CC in youth…

Fitch, Allison; Fein, Deborah A.; Eigsti, Inge-Marie – Journal of Autism and Developmental Disorders, 2015
Individuals with high-functioning autism (HFA) have a cognitive style that privileges local over global or gestalt details. While not a core symptom of autism, individuals with HFA seem to reliably show this bias. Our lab has been studying a sample of children who have overcome their early ASD diagnoses, showing "optimal outcomes" (OO).…
