Editing Squirrel monkey (section)

=== Cooperation studies ===
[[Cooperation]] is largely evident in human primates. Squirrel monkeys do not often display cooperation in the wild, while many other nonhuman primates do. Studies have been done to suggest that female squirrel monkeys show disadvantageous inequity aversion as it pertains to food rewards. However, the same could not be said for male squirrel monkeys. More studies need to be done on squirrel monkey behavior to determine why squirrel monkeys rarely show cooperation, and whether disadvantageous inequity aversion is a relevant factor.<ref>{{Citation|last=Thorington|first=Richard W.|title=Observations of Squirrel Monkeys in a Colombian Forest|date=1968|url=http://dx.doi.org/10.1016/b978-1-4832-3310-9.50008-4|work=The Squirrel Monkey|pages=69–85|publisher=Elsevier|doi=10.1016/b978-1-4832-3310-9.50008-4|isbn=978-1-4832-3310-9|access-date=2021-04-01}}</ref>
