I'm looking mainly at Human perception of time depending on age. It's a very cog sci question that doesn't really related to the underlying biology but the explanations may involve it. Does it belong?
Have you been over to cogsci.SE yet? I don't think anyone would mind me pointing it out, as there are no doubt others like me that would like to see both sites thrive. This very issue has been discussed on their meta as well.
Since everyone is still in Beta, it's a good time to determine the division of labor between the two for topics like neuroscience/cognitive science, so that there's cross-fertilization rather than competition.
If it's exclusively a biology question, it's probably better off staying here, obviously, but if there's some ambiguity, ask on the metas to gauge appropriateness like you would for any other SE site.
