Dr. Laszlo Erdodi is a clinical neuropsychologist and Associate Professor of Psychology at the University of Windsor. He is a licensed Psychologist in Ontario. He earned his Ph.D. in Clinical Psychology from Eastern Michigan University, with a pre-doctoral internship at the London Health Sciences Centre in neuropsychology. He completed his post-doctoral fellowship in Neuropsychology at the Geisel School of Medicine at Dartmouth.
His research interests revolve around performance validity tests (PVTs) within neuropsychological assessment, improving psychometric tools for assessing a variety of neuropsychiatric conditions, the effect of psychogenic interference and limited English proficiency on performance on cognitive testing. He has developed a multivariate procedure for aggregating embedded validity indicators that captures both the number and extent of PVT failures, providing a more nuanced measure of performance validity.
Dr. Christopher Abeare is a clinical neuropsychologist and Professor of Psychology at the University of Windsor. He is a licensed Psychologist in Ontario and Michigan. He earned his Ph.D. in Clinical Psychology from Wayne State University, with a pre-doctoral internship at the Veterans Administration Hospital in Ann Arbor, Michigan. He conducted post-doctoral supervised practice at the Rehabilitation Institute of Michigan as well as in private practice.
His research interests revolve around assessment of traumatic brain injury and sport-related concussion, with emphasis on the assessment of emotional and cognitive functioning as well as performance validity.
