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.…

Zhou, Han-yu; Yang, Han-xue; Shi, Li-juan; Lui, Simon S. Y.; Cheung, Eric F. C.; Chan, Raymond C. K. – Journal of Autism and Developmental Disorders, 2021
Atypical sensory processing has recently gained much research interest as a key domain of autistic symptoms. Individuals with autism spectrum disorder (ASD) exhibit difficulties in processing the temporal aspects of sensory inputs, and show altered behavioural responses to sensory stimuli (i.e., sensory responsiveness). The present study examined…

McGonigle-Chalmers, Maggie; McCrohan, Fiona – International Journal of Developmental Disabilities, 2018
Objectives: The aim of the study is to help identify the nature of impaired executive functioning (EF) in children with autism spectrum disorder (ASD). It is also argued that participant sampling by age alone should inform experimental research on EF, as selection through IQ matching may weaken any experimental effects. Methods: Sixteen children…

Moreno-Pérez, Francisco J.; Rodríguez-Ortiz, Isabel R.; Tavares, Gema; Saldaña, David – International Journal of Language & Communication Disorders, 2020
Background: It has been established that people with autism spectrum disorder (ASD) often have difficulties understanding spoken language. Understanding reflexive and clitic pronouns is vital to establishing reference-based inference, but it is as yet unclear whether such constructions pose specific difficulties for those with ASD. Pronoun…

Eigsti, Inge-Marie; Irvine, Christina A. – Language Acquisition: A Journal of Developmental Linguistics, 2021
This study tests the role of verbal mediation during theory of mind processing in autism spectrum disorder (ASD). Adolescents with ASD or typical development completed a false belief task while simultaneously performing a verbal or nonverbal load task. There was no group difference in false belief "accuracy;" however, under verbal load,…

Vogan, Vanessa M.; Morgan, Benjamin R.; Smith, Mary Lou; Taylor, Margot J. – Autism: The International Journal of Research and Practice, 2019
This study examined functional changes longitudinally over 2 years in neural correlates associated with working memory in youth with and without autism spectrum disorder, and the impact of increasing cognitive load. We used functional magnetic resonance imaging and a visuo-spatial 1-back task with four levels of difficulty. A total of 14 children…

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).…

Walsh, Jennifer A.; Creighton, Sarah E.; Rutherford, M. D. – Journal of Autism and Developmental Disorders, 2016
Some, but not all, relevant studies have revealed face processing deficits among those with autism spectrum disorder (ASD). In particular, deficits are revealed in face processing tasks that involve emotion perception. The current study examined whether either deficits in processing emotional expression or deficits in processing social cognitive…

Hessels, Roy S.; Hooge, Ignace T. C.; Snijders, Tineke M.; Kemner, Chantal – Journal of Autism and Developmental Disorders, 2014
Superiority in visual search for individuals diagnosed with autism spectrum disorder (ASD) is a well-reported finding. We administered two visual search tasks to individuals with ASD and matched controls. One showed no difference between the groups, and one did show the expected superior performance for individuals with ASD. These results offer an…

Remington, Anna; Campbell, Ruth; Swettenham, John – Autism: The International Journal of Research and Practice, 2012
In recent years there has been a growing interest in the role of attention in the processing of social stimuli in individuals with autism spectrum disorders (ASD). Research has demonstrated that, for typical adults, faces have a special status in attention and are processed in an automatic and mandatory fashion even when participants attempt to…

Reimer, Bryan; Fried, Ronna; Mehler, Bruce; Joshi, Gagan; Bolfek, Anela; Godfrey, Kathryn M.; Zhao, Nan; Goldin, Rachel; Biederman, Joseph – Journal of Autism and Developmental Disorders, 2013
Although it is speculated that impairments associated with autism spectrum disorder (ASD) will adversely affect driving performance, little is known about the actual extent and nature of the presumed deficits. Ten males (18-24 years of age) with a diagnosis of high functioning autism and 10 age matched community controls were recruited for a…

Poljac, Edita; Poljac, Ervin; Yeung, Nick – Journal of Autism and Developmental Disorders, 2012
Impairments in cognitive control generating deviant adaptive cognition have been proposed to account for the strong preference for repetitive behavior in autism. We examined if this preference reflects intentional deficits rather than problems in task execution in the broader autism phenotype using the Autism-Spectrum Quotient (AQ). Participants…

Bayliss, Andrew P.; Kritikos, Ada – Journal of Autism and Developmental Disorders, 2011
A fundamental task of the cognitive system is to prioritize behaviourally relevant sensory inputs for processing at the expense of irrelevant inputs. In a study of neurotypical participants (n = 179), we utilized a brief flanker interference task while varying the perceptual load of the visual display. Typically, increasing perceptual load (i.e.,…

Endedijk, Hinke; Denessen, Eddie; Hendriks, Angelique W. – Learning and Individual Differences, 2011
Despite the fact that homework forms an important cornerstone of student development, many students fail to capitalize on the long-term benefits of doing homework. Several executive skills, including cognitive flexibility, monitoring and planning are suggested as prerequisites for the completion of homework. It follows that homework difficulties…

Loucas, Tom; Riches, Nick Greatorex; Charman, Tony; Pickles, Andrew; Simonoff, Emily; Chandler, Susie; Baird, Gillian – International Journal of Language & Communication Disorders, 2010
Background: The cognitive bases of language impairment in specific language impairment (SLI) and autism spectrum disorders (ASD) were investigated in a novel non-word comparison task which manipulated phonological short-term memory (PSTM) and speech perception, both implicated in poor non-word repetition. Aims: This study aimed to investigate the…
