Latest: Apes possess a “theory of mind”

Does Jasongo (bonobo) at the Leipzig Zoo have a theory of mind?

From Catherine Caruso at Scientific American:

In the study, published Thursday in Science, a team of scientists recorded the eye movements of three great ape species while the animals watched videos of a man searching for a hidden object that had been moved without his knowledge, and found that they looked more frequently at the location where the man expected the object to be (a belief the apes knew was false), even though the object was no longer there. The findings suggest the apes were able to intuit what the human was thinking.

Apes from all three species consistently passed the test; even though the animals knew King Kong or the rock was gone, when the researcher returned to search for it, they consistently looked at the hay bale or box where the person had last seen the object and presumably still thought it was hidden. These results are particularly surprising because they challenge the large body of previous work that suggests great apes are not capable of comprehending beliefs that are untrue. “People have thought for awhile that false-belief understanding is unique to humans,” Krupenye says, “and so this suggests that apes do have at least a basic, implicit understanding of false belief, which has been seen as a signature of theory of mind.” More.

This is the best they can do? Who would really be surprised if some dogs, cats, and ravens can figure out whether another creature knows where something has been hidden? (Especially if the dog, cat, or raven hid it himself.)

Others are skeptical of that interpretation, however. … “The issue is that subjects could use a simple behavior rule—‘agents search for things where they last saw them’—to pass the tests without understanding anything about the agent’s false beliefs,” they explained.

Yes exactly. A smart bird might figure out what the gorilla suit is likely to do next, provided the bird has some reason to care.

Actually, “theory of mind” is just another one of those terms of art that enable naturalists to avoid the obvious problem: If apes can really do anything special intellectually, why are they still swinging in the trees? Come up with an answer to that and we will listen.

Watch for the casuistry to become ever more sophisticated, unless the public gets dumber or less interested in science.

This story was picked up at Nature (Helen Shen, Apes can tell if you’ve been duped) and The Conversation “Can great apes read your mind?” (Christopher Krupenye, one of the authors).

TWSYF, Chimps can do what they do. Obviously, they are not humans, physically or mentally. But they're pretty darn smart for animals (who obviously have close genetic similarities to us humans.) I'm not an atheist, and all of this should be obvious to anyone, atheist or theist. What does this have to do with atheism? mike1962
Silly atheists. How much more money and time will you waste on this rubbish? Your entire worldview is fraudulent and bankrupt of any socially redeeming value. Stop being so stupid. Truth Will Set You Free
