Dr. 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.
In the fall of 2009 Sarah moved from New Zealand to New York to take up a post-doctoral fellowship at Queens College of the City University of New York under the mentorship of Distinguished Professor Jeffrey Halperin. During her time at Queens College, Sarah worked on two of Dr. Halperin’s federally-funded studies, the Queens College Preschool Project (QCPP) and Non-Pharmacological Interventions for Preschoolers with ADHD (NIPA). One of the key aims of the QCPP study is to understand the relation between children’s neuropsychological development and change in their ADHD severity over time. The NIPA study evaluated the efficacy of two non-pharmacological treatments for young children with ADHD.
In the fall of 2013 Sarah joined the CCNY faculty as an Assistant Professor where she continues to research ADHD. Specifically, she is interested in better understanding the mechanisms that drive long-term outcomes in individuals with ADHD and in developing evidence-based interventions for ADHD.
