in 1949, Sally Boysen was raised in Sandusky, Ohio.
After studying anthropolgy, psychology and zoology as
an undergraduate at Ohio State University, Boysen completed
her Ph.D. in 1984. Her current research interests center
on animal cognition. She is particularly interested
in the acquisition of counting abilities and numerical
competence in non-human primates. Boysen also studies
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.
