Examining perceptual load capacity in Autism Spectrum Disorders and trait anxiety
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Perceptual load theory posits that there is a limited amount of information a person can perceive at any given time and information is processed ...
Structural-morphometric examination of thalamic nuclei in individuals with autism spectrum disorders
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The thalamus has been implicated as a potential source of neural disruption in autism spectrum disorders (ASD). This subcortical nuclear complex is ...
The effects of tetrahydrobiopterin (BH4) treatement on nonverbal working memory-related brain activations and connectivity in individuals with phenylketonuria
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Previous research suggests that phenylketonuria (PKU) is associated with disruptions in structural and functional connectivity that may contribute to ...
Cognitive processes contributing to visual working memory performance in individuals with autism spectrum disorder /
(University of Missouri--Columbia, 2016)
Previous investigations of working memory performance in individuals with Autism Spectrum Disorder (ASD) have yielded mixed findings (e.g., Kenworthy, Yerys, Anthony, and Wallace, 2008; Geurts, de Vris, and van den Bergh, ...
Inhibitory control in male and female adolescents with autism spectrum disorder (ASD)
(University of Missouri--Columbia, 2022)
Recent research suggests that individuals with autism spectrum disorder (ASD) experience particular difficulty resisting interference from visual distractors (RIVD) relative to other aspects of inhibitory control (e.g., ...

(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Phenylketonuria (PKU) is a rare autosomal recessive disorder characterized by a disruption in the ability to metabolize phenylalanine (phe) into tyrosine, ...
Motor learning in children with an autism spectrum disorder
(University of Missouri--Columbia, 2013)

Relationship between repetitive behaviors and executive function in high functioning children with autism
(University of Missouri--Columbia, 2011)
It has been theorized that impairments in executive function may contribute to the repetitive behavior symptomatology associated with ASD. This study further elucidates the nature of the relationship between ASD-related ...
The impact of secondary working memory demands on inhibitory performance in individuals with and without autism spectrum disorder
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Executive function is postulated as one of the core areas of impairment in individuals with an autism spectrum disorder (ASD). When measured in ...
