Elias, Rebecca; White, Susan W. – Journal of Autism and Developmental Disorders, 2020
Social motivation in individuals with ASD is inferred from the observation of overt behaviors and neurological correlates. Motivation, however, can be distinguishable from overt behavior and neurologic reactivity. Nevertheless, few studies have examined the cognitive processes that may influence goal-directed tasks involved in social interaction.…

Keehn, Brandon; Westerfield, Marissa; Townsend, Jeanne – Journal of Autism and Developmental Disorders, 2019
This study investigates how task-irrelevant auditory information is processed in children with autism spectrum disorder (ASD). Eighteen children with ASD and 19 age- and IQ-matched typically developing (TD) children were presented with semantically-congruent and incongruent picture-sound pairs, and in separate tasks were instructed to attend to…

Van der Donck, Stephanie; Dzhelyova, Milena; Vettori, Sofie; Thielen, Hella; Steyaert, Jean; Rossion, Bruno; Boets, Bart – Journal of Autism and Developmental Disorders, 2019
We objectively quantified the neural sensitivity of school-aged boys with and without autism spectrum disorder (ASD) to detect briefly presented fearful expressions by combining fast periodic visual stimulation with frequency-tagging electroencephalography. Images of neutral faces were presented at 6 Hz, periodically interleaved with fearful…

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…

Ghosn, Farah; Perea, Manuel; Castelló, Javier; Vázquez, Miguel Ángel; Yáñez, Núria; Marcos, Inmaculada; Sahuquillo, Rosa; Vento, Máximo; García-Blanco, Ana – Journal of Autism and Developmental Disorders, 2019
Previous research has shown attentional biases in children with autism spectrum disorders (ASD) when processing distressing information. This study examined these attentional patterns as a function of the type of stimulus (scenes and faces) and the stimulus valence (happy, sad, threatening, neutral) using a within-subject design. A dot-probe was…

Nicholson, Toby; Williams, David; Carpenter, Katie; Kallitsounaki, Aimilia – Journal of Autism and Developmental Disorders, 2019
Interoception (the ability to sense what's going on inside one's body) is considered integral to many higher-order cognitive processes. Some have speculated that impaired interoception may underpin some features of ASD. Yet, in Experiment 1, we found no evidence of a between-group difference in either cardiac or respiratory interoceptive accuracy…

Pokorny, Jennifer J.; Hatt, Naomi V.; Rogers, Sally J.; Rivera, Susan M. – Journal of Autism and Developmental Disorders, 2018
Understanding another's actions, including what they are doing and why they are doing it, can be difficult for individuals with autism spectrum disorder (ASD). This understanding is supported by the action observation (AON) and mentalizing (MZN) networks, as well as the superior temporal sulcus. We examined these areas in children with ASD and…

Booth, Rhonda D. L.; Happé, Francesca G. E. – Journal of Autism and Developmental Disorders, 2018
Frith's original notion of 'weak central coherence' suggested that increased local processing in autism spectrum disorder (ASD) resulted from reduced global processing. More recent accounts have emphasised superior local perception and suggested intact global integration. However, tasks often place local and global processing in direct trade-off,…

Snape, Simon; Krott, Andrea; McCleery, Joseph P. – Journal of Autism and Developmental Disorders, 2018
Individuals with ASD seem to construct categories via processes different to typically developing individuals. We examined whether individuals with ASD engage in structural alignment of exemplars when constructing categories. We taught children with ASD and typically developing children novel nouns for either single or multiple exemplars, and then…

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…

Lortie, Melissa; Proulx-Bégin, Léa; Saint-Amour, Dave; Cousineau, Dominique; Théoret, Hugo; Lepage, Jean-François – Journal of Autism and Developmental Disorders, 2017
There is debate whether social impairments in autism spectrum disorder (ASD) are truly domain-specific, or if they reflect generalized deficits in lower-level cognitive processes. To solve this issue, we used auditory-evoked EEG responses to assess novelty detection (MMN component) and involuntary attentional orientation (P3 component) induced by…

Ziermans, Tim; Swaab, Hanna; Stockmann, Alexander; de Bruin, Esther; van Rijn, Sophie – Journal of Autism and Developmental Disorders, 2017
Formal thought disorder (FTD) is a disruption in the flow of thought and a common feature in psychotic disorders and autism spectrum disorder (ASD). Executive dysfunction has often been associated with FTD, yet for ASD convincing evidence is lacking. This study investigated FTD and three core executive functions in 50 young children and…

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…

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…

Rubinstein-Taybi syndrome (RTS) is a rare genetic disease that associates intellectual disability with somatic characteristics. We have conducted a study of the overall motor abilities of RTS participants. Static postural performance as well as gait parameters were somewhat decreased, although not significantly compared to typically developing…
