Understanding language is a key component to being able to understand the directions for the false-belief test, and researchers have had to get creative to utilize this test in the research of non-human primates' theory of mind. Recent technology has enabled researchers to closely resemble the false-belief task without needing to use language.
The authors conclude, "this study found evidence that humans can perform better than suggested by Matsuzawa in the limited-hold memory task. However, human performance is still below that of chimpanzees. This difference appears to stem from an inability to keep the location of symbols in working memory" [5]
In one approach testing monkeys, rhesus macaques (Macaca mulatta) are able to "steal" a contested grape from one of two human competitors. In six experiments, the macaques selectively stole the grape from a human who was incapable of seeing the grape, rather than from the human who was visually aware. [ 26 ]
The great apes (Hominidae) show some cognitive and empathic abilities. Chimpanzees can make tools and use them to acquire foods and for social displays; they have mildly complex hunting strategies requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can learn to use symbols and understand aspects of human language including some ...
“The idea that this stuff could actually get smarter than people — a few people believed that,” Hinton told the New York Times. “But most people thought it was way off. “But most people ...
A monkey drinking Frooti from a juice box using its hands. The mind and behavior of non-human animals has captivated the human imagination for centuries. Many writers, such as Descartes, have speculated about the presence or absence of the animal mind. [7]
The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [72] - although humans may have four or five. [78] The main hominid molar cusp ( hypocone ) evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost.
Nim's chaotic upbringing, documented in Elizabeth Hess's biography Nim Chimpsky: The Chimp Who Would Be Human, negatively impacted not only his behavior but his performance on language-related tasks. Even Terrace acknowledged this problem, noting that Nim's "emotional turmoil" was a "major obstacle" in his progress.
