Dr. Jennifer O’Brien uses behavioral and electroencephalography (EEG) methods to investigate human visual perception and attention. Her focus is on how our attentional system prioritizes and processes information across the lifespan.
O’Brien is the recipient of numerous internal and external research grants. In 2021, she was part of a team that received a $44.5-million grant from the National Institute on Aging (NIA) for a clinical trial seeking to reduce the risk of Alzheimer’s disease in cognitively healthy older adults. In 2022, she and colleagues received a $24.3-million grant from the NIA for a clinical trial seeking to reduce the risk of Alzheimer’s disease in older adults with cognitive impairment. O’Brien and her colleagues are using the funding to determine whether cognitive training can reduce incidence of cognitive decline.
O’Brien teaches graduate and undergraduate courses in research methods, statistics and physiological psychology. An avid instructor and science advocate, O’Brien trains her students in the scientific method and how to conduct scientific psychology experiments. She is the recipient of an outstanding advisor award for her work with students.
Ph.D. Bangor University
Human perception, attention, decision-making, and cognitive aging
Dr. O’Brien’s research focuses on the fundamental mechanisms behind perception, attention, and decision-making in healthy adults and in changes to these systems during normal and abnormal aging using both behavioral and neurophysiologicial methods. She is especially interested in the integral role that motivational value has in the way we perceive and attend to stimuli in our environment.
