ProfileDr. Sarah O'Neill received her Ph.D. in Psychology and Postgraduate Diploma in Clinical Psychology from the University of Otago, Dunedin, New Zealand. She worked with Dr. Rachel Zajac to investigate factors that influence children's responses to cross-examination style questioning. Specifically, she sought to understand the mechanisms that account for children's often inconsistent and inaccurate responding to cross-examination questions; cognitive individual difference factors that may affect children's cross-examination performance; and the effectiveness of an intervention designed to improve children's cross-examination performance.

Broadly, my research is on Attention-Deficit/Hyperactivity Disorder (ADHD). ADHD is a neurodevelopmental disorder, thus for most individuals, symptoms emerge in early childhood. Although some children who show elevated symptomatology during preschool do not go on to develop ADHD, many do go on to receive an ADHD diagnosis at school age; for the majority of these children, ADHD persists through adolescence and adulthood with varying degrees of severity. Given the high prevalence of the disorder, its chronicity, and associated functional impairment, better understanding of the mechanisms driving long-term outcomes is necessary, as is the development of evidence-based interventions. Currently I am working with students and colleagues on the following topics:
Why are children with ADHD at risk for reading problems?
The co-occurrence of reading disorder in children with ADHD, and of ADHD in children with reading disorder is around 15-40%, irrespective of whether community or clinical samples are recruited. Several studies to date suggest that the link between reading problems and ADHD is stronger for inattention than for hyperactivity/impulsivity. It has been proposed that attention is necessary for the development of pre-reading skills, and this may be why we see reading difficulties in children with ADHD. We are investigating the pathways among inattention, language ability, and reading achievement over time to better understand how these variables are related to each other, and how their interplay over time affects academic achievement during school-age.
What role does executive dysfunction play in ADHD?
Several prominent theories of ADHD emphasize the importance of higher order cognitive dysfunction, such as working memory difficulties and behavioral disinhibition, as central to ADHD etiology. It is clear, however, that successful performance on putative executive function tasks does not solely depend on the higher-order cognitive ability of interest, but also on many non-executive processes (e.g., processing efficiency, motivation). We are investigating how these more basic processes impact on an individual's performance on executive function tasks to better understand how and to what extent executive function deficits are manifested in children and adolescents with ADHD.
How does physical exercise impact cognitive functioning?
There is a robust literature, primarily in animals and in aging human populations, showing that physical exercise positively impacts brain structure and cognitive performance. Less is known, however, about the impact of physical exercise on the cognitive functioning of young adults and children; this is particularly the case for individuals with ADHD. We are investigating the acute effects of moderate intensity exercise on young adults' working memory and different aspects of attention. Furthermore, we are also interested in better understanding the factors that may moderate the relation between exercise and cognitive functioning, such as body mass index, fitness level, ADHD symptom severity, and severity of internalizing problems.
