Dr. DeLong is a cognitive psychologist with expertise in comparative cognition and perception. She has a B.A. from New College of Florida and a M.A. and Ph.D. from the University of Hawaii.  Prior to coming to RIT, she was a Visiting Professor of Psychology at New College of Florida and spent four years as a postdoctoral research associate at Brown University. She joined the Psychology Department at RIT in 2008.

Dr. DeLong’s research interests are in comparative cognition, human cognition and perception, and bioacoustics. Her past research has focused on cognitive representation and auditory perception in dolphins and bats. She is currently involved in collaborative research projects on dolphin biosonar. Her recent research studies include visual object recognition and number discrimination in fish, visual object recognition in North American river otters, and artificial neural network modeling of human performance on auditory object discrimination tasks.   Please see Dr. DeLong’s website for more information about her Comparative Cognition and Perception Lab.

Dr. DeLong teaches classes in Cognitive Psychology, Perception, Language and Thought, Memory and Attention, Learning and Behavior, Research Methods, Seminar in Psychology, Senior Project in Psychology, Co-op, Independent Study, and Graduate Cognition.
