comment Trying to understand equations in Karl Friston article
+1 for also being confused by much of Fristen's writing.

comment Are our brains just energy conserving systems?
I think you be either alluding to or interested in Friston's free energy principle: en.wikipedia.org/wiki/Free_energy_principle

comment Is being naked good for you?
I feel like this question, as it stands, lacks any theoretic motivation. There are an infinite number of questions we could ask about the human mind, but only a small finite amount of resources. If you could broaden the context of why you are interested in this question, then perhaps some relevant research literature could be found to answer it, even if they only use related constructs (e.g. work on activism or modesty or fashion depending on your motivation for asking).

comment Regarding “a human brain can hold enough information to fill 10 libraries”, can we quantify the memory required for a given task?
'Synaptic connections created' is a pretty bad metric for memory, since most memories are created by changing the weights of existing connections rather than creating new connections.

comment Does intermittent fasting increase intelligence?
Hi John, just wanted to give you some feedback on why I think your question wasn't feel received here. The main problem is you don't present your rational for thinking why I.F. might have an effect on intelligence. You should try and ground your question in the existing literature if want the community here to be of much help.

comment What are the negative effects of meditation?
Not a drawback unique to mediation, but opportunity cost tends to be neglected in such discussions. e.g. spending 2 hours mediating might reduce stress, but perhaps TV reduces stress faster.

comment Any models that act using both streams of visual processing?
Perhaps my comment was too strongly worded, as I too see links as a vital part of a good answer. But the problem here is that your answer text doesn't give any indication as to how the link helps to answer my question.

comment Any models that act using both streams of visual processing?
I've tried reading the chapter you linked, but several pages aren't available since its only a google books preview, so its hard to get a sense of what their model is. Could you briefly summarize their model in your answer? Self contained answers are generally encouraged here anyways. Thanks again for your time!

comment Any models that act using both streams of visual processing?
Thanks for the input! However, perhaps I'm misreading this, but I don't quite see how this answers my question. I'm interested in how we solve tasks where both dorsal and ventral stream information is needed. How are hemispheric asymmetries related to this?

comment Why do people laugh in serious situations?
Maybe its like the ole' "dont think of a purple elephant" trick: you tell yourself you definitely shouldn't laugh right now, then can't stop thinking about it, and then burst out in chuckles.

comment What is the difference between drug withdrawal and sleep deprivation effects?
Interesting question! Not sure if I'll get around to a full answer, but wanted to let you know that sleep almost certainly has a purpose, and probably has several. The one I know the most about is memory consolidation, where sleep is used to replay the day's events to better train the brain

comment What is the null hypothesis, when there is no research hypothesis?
This seems way out of scope... philosopy S.E. might be a better place, since this deals more with the philosophy of science rather any particular field.

comment How can schemas be applied to website design?
Hmm, the titular question is quite interesting, but the side questions (a-d) all seem very problematic. I don't mean to be overly harsh, but my answer to all of them would be: None of them are true, and I'm not sure what led you to think that they could be. You should unpack your current beliefs on what schema are, since it appears you might be working from some faulty premises.

comment Is there any recent work on modeling how we rapidly acquire new knowledge?
Also, "the brain processes information then encodes its conclusions into memory" -- that whole process is generally believed to involve either changing synaptic weights and/or neural activation patterns. Both of which can be (and generally are) modeled in artificial neural networks.

comment Is there any recent work on modeling how we rapidly acquire new knowledge?
Thanks for taking an interest in my question! However, I'm afraid I strongly disagree with the statements you've made in this answer. The vast majority of neural network models used in cognitive psychology aren't meant to take place over an evolutionary time scale. They are meant to model the learning processes going on during an individual's lifetime. I could site sources, but I think this fact is fairly well accepted.

comment Aesthetic preference for even or odd numbers
Ah, that clarifies things, so you mean aesthetic preference? If so, making that explicit would be helpful. Also, you should try google scholaring "numeric aesthetic preferences" something similar to get some background.

comment What happens to a person's frontal lobes when they have a breakdown from stress?
I'd suggest changing the question to something akin to "what are the neural correlates of a mental breakdown" or even "Is a mental breakdown detectable at the neural level?" The current question presupposes the lobe granularity is the right one, which we shouldn't accept without some cited research.

comment Aesthetic preference for even or odd numbers
"Prefer" is too vague to be answered in a rigorous way. You should give some examples of what you mean by number preference or try and operationalize it in some other manner.

comment Any research on how we use visual category information in visuomotor tasks?
Wow, thanks for the great response! That Mahon quote was just the kind of thing I was looking for. Looks like I've got my readings for the next week :)
