Department Faculty

Sally (Sarah) Boysen

Dr. Boysen received her Ph.D. in 1984 from The Ohio State University. Her current research interests are animal cognition, with particular interest in the acquisition of counting abilities and numerical competence in nonhuman primates, cognitive development in the great apes, including attribution, self-recognition, and intentional behavior, and social behavior and tool use in captive lowland gorillas. Collaborative research with Gary Berntson includes the application of non-invasive psycho-physiological measures to attention and cognition in primates, and cardiac indices of visual and auditory recognition in the great apes. Boysen is currently Consulting Editor for the Journal of Comparative Psychology.
