Their "reinterpretation hypothesis" explains away evidence supporting attribution of mental states to others in chimpanzees as merely evidence of risk-based learning; that is, the chimpanzees learn through experience that certain behaviors in other chimpanzees have a probability of leading to certain responses, without necessarily attributing ...
“The sequence of steps that you would only ever have imagined seeing with an incredibly intelligent animal like a chimpanzee or a dolphin, they see in the cleaner wrasse,” Birch said.
Matsuzawa, whose research focuses on chimpanzee intelligence, suggests the tradeoff hypothesis as a possible explanation as to why chimpanzees have better memory than humans for immediately capturing and retaining visual stimuli in his paper "Symbolic representation of number in chimpanzees". [1]
Group of chimpanzees. In primatology, the Machiavellian intelligence or social brain hypothesis describes the capacity of primates to manuever in complex social groups.

That said, the test for sentience is the degree to which an animal (human, dolphin, or chimpanzee) can experience higher level emotions. Dolphins pass this test hands down.
Started in 1978, it is one of the longest running laboratory research projects on chimpanzee intelligence. Matsuzawa has been a part of the project since the beginning. Matsuzawa has also studied tool use in the wild chimpanzees at Bossou, Guinea, West Africa since 1986. The bossou chimpanzee community consists of about 12 individuals and has ...
The human and chimpanzee evolutionary lineages split about 6.9 million to 9 million years ago, according to research published in June. Studying chimpanzee behavior may offer insight into our own ...
