This might be an artifact of the battery of tests they use, but it does weaken their results a bit in my opinion.steve hsuhttp://duende.uoregon.edu/noreply@blogger.comtag:blogger.com,1999:blog-5880610.post-24554096391528288692014-07-21T21:55:01.407-04:002014-07-21T21:55:01.407-04:00I already asked the authors for their data.

I would like to see individual tribes of monkeys compared to other tribes with their own sets of social codes and languages.

Nevertheless, 0.5 is probably a lower bound.steve hsuhttp://duende.uoregon.edu/noreply@blogger.comtag:blogger.com,1999:blog-5880610.post-30447844868558343372014-07-11T18:02:27.147-04:002014-07-11T18:02:27.147-04:00> I would be shocked if you could do cognitive ...> I would be shocked if you could do cognitive tests on a monkey with very<br /> high retest reliability.

Holding their attention is a bit more difficult than with humans! This contributes more noise to the g measurement and decreases the deduced heritability.steve hsuhttp://duende.uoregon.edu/noreply@blogger.comtag:blogger.com,1999:blog-5880610.post-73553648543243575992014-07-10T22:34:05.772-04:002014-07-10T22:34:05.772-04:00chimpanzee has photographic memory, test yourself ...chimpanzee has photographic memory, test yourself against them,<br /><br />http://www.youtube.com/watch?v=XRix_vuAmrMdxie48noreply@blogger.com
