Bruce Lee also promoted sleeping a lot, but then again we know little about his intelligence and he had a ridiculous workout schedule, the guy must have had a huge metabolism and the article Jason posted said that animals with high metabolisms for their size sleep more as well.<BR/><BR/>I wonder is there a link between having a high metabolism for your size and intelligence?UncleTomRuckusInGoodWhiteWorldhttps://www.blogger.com/profile/07508650487951730570noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-44997141643035066012008-06-27T00:06:00.000+03:002008-06-27T00:06:00.000+03:00"There are remarkable racial differences in report..."There are remarkable racial differences in reported napping and nighttime sleep patterns beginning as early as age 3 and extending to at least 8 years of age. These differences are independent of commonly investigated demographic factors... At age 8, 39.1% of black children were reported to nap, compared with only 4.9% of white children. Black children also napped significantly more days per week, had shorter average nocturnal sleep durations, and slept significantly less on weekdays than on weekend nights."<BR/><BR/>http://pediatrics.aappublications.org/cgi/content/abstract/115/1/S1/225Jason Malloyhttps://www.blogger.com/profile/04855482153162314172noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-7662256908034124002008-06-26T23:53:00.000+03:002008-06-26T23:53:00.000+03:00"... adolescents who are Evening-types appear to b..."... adolescents who are Evening-types appear to be at risk for poor academic performance and Evening-types appear to be at risk for behavioral adjustment problems."<BR/><BR/>http://dx.doi.org/10.1016/j.paid.2006.07.008Jason Malloyhttps://www.blogger.com/profile/04855482153162314172noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-78007444508389769642008-06-26T23:50:00.000+03:002008-06-26T23:50:00.000+03:00How all this selection might be reflected in pheno...How all this selection might be reflected in phenotype is a good question.<BR/><BR/>A study in P&ID found that there was a significant circadian phase shift at adolescence - such that more people begin to prefer eveningness over morningness. Although the sample sizes were low they found that "Hispanic children change least with age in their morningness–eveningness preference whereas African American children change most. For both Asian and Caucasian children, the degree of change in their morningness–eveningness preference seems to fall in the middle relative to Hispanic and African American children, and the patterns of change appear to be similar to each other."<BR/><BR/><BR/>http://www.psych.utoronto.ca/users/hasher/PDF/Children%20Time-of-day%20study.pdfJason Malloyhttps://www.blogger.com/profile/04855482153162314172noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-50646538551449596292008-06-26T21:00:00.000+03:002008-06-26T21:00:00.000+03:00REM-sleep is correlated with intelligence in the a...REM-sleep is correlated with intelligence in the animal-kingdom.
