One of the researchers, Kazuo Fujita, professor of comparative cognition at Kyoto University, notes, "We discovered for the first time that dogs make social and emotional evaluations of people regardless of their direct interest ... This ability is one of key factors in building a highly collaborative society and this study shows that dogs share that ability with humans."
Apes are susceptible to spin.
The other study about which I learned also is very interesting and is summarized in an essay in Scientific American Mind by Francine Russo called "Like Humans, Apes Are Susceptible to Spin." Duke University's Christopher Krupenye and Brian Hare and Yale University's Alexandra Rosati studied 23 chimpanzees and 17 bonobos and:
"offered them options for choosing food: either one or two fruits versus a constant number of peanuts. Sometimes the apes were shown one piece of fruit each time they made the selection, but half the time they were given two: positive framing. In other trials, the apes were initially presented two pieces of fruit, but half the time they got only one: negative framing. Regardless of the framing, the apes ended up with an identical quantity of fruit."
