Chimpanzees (Pan troglodytes)
Over the years, five resident chimpanzees have lived at the LRC and contributed significantly to research on language and cognition. Three chimpanzees--Lana, Sherman, and Mercury--currently participate in various behavioral research projects. Lana and Sherman acquired symbolic-communication skills using a language analogue, in research that began with Lana in 1971. The apes are currently active in a wide array of comparative cognition studies: spatial memory, delay of gratification, numerical cognition, analogical reasoning, and cooperation.
|Rhesus Monkeys (Macaca mulatta)
Eight males currently make up the LRC's rhesus team productively working at computerized testing systems on tasks designed to assess learning and cognitive skills such as memory, knowledge of numbers, concepts and reasoning ability.
|Capuchin Monkeys (Cebus apella)
The LRC is home to three groups of socially-housed of capuchin monkeys (N = 22) actively participating in projects designed to evaluate a variety of social behavior including cooperation as well as computerized tasks to assess learning and cognition.
