Nov. 19, 2013 — Are monkeys, like humans, able to ascertain where objects are located without much more than a sideways glance? Quite likely, says Lau Andersen of the Aarhus University in Denmark, lead author of a study conducted at the Yerkes National Primate Research Center of Emory University, published in Springer's journal Animal Cognition. The study finds that monkeys are able to localize stimuli they do not perceive.
Humans are able to locate, and even side-step, objects in their peripheral vision, sometimes before they perceive the object even being present. Andersen and colleagues therefore wanted to find out if visually guided action and visual perception also occurred independently in other primates.
