Jun 10	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.
Jun 5	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.
May 20	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.
May 20	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.
May 18	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.
May 17	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.
May 17	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.
Mar 27	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 :)
Mar 27	comment	Any research on how we use visual category information in visuomotor tasks? Good to be back :)
Mar 27	comment	How to tell a diagnosis from an actual state? Perhaps this is tad to philosophical, but could you give an example where we can separate a human construct from an 'actual state'?
Mar 20	comment	EEG correlates of handedness "It must have correlates in EEG" -- No. It must have some neural correlate. EEG can capture only a small percentage of behavioral phenomena due to its relatively course spatial frequency and inability to record activity in more medial brain regions. I'd broaden your search accordingly; perhaps that will lead to more relevant literature.
Mar 15	comment	Any attempts at testing or modeling the 'cognitive conception' of language? Just realized Gary Lupyan had the same advisor as me; small world!
Mar 15	comment	Any attempts at testing or modeling the 'cognitive conception' of language? Having a CS degree, I very much realize that serial processing is much easier than massive parallelism for both computer hardware and software engineers to produce. My claim is that serial processing is harder for humans, not harder in some general sense. This is a somewhat controversial claim, but has support from evolutionary psychology (other animals are terrible at symbol processing) and neuro-anatomy (the brain is massively parallel).
Mar 15	comment	Any attempts at testing or modeling the 'cognitive conception' of language? I agree that there are conflicting intuitions on this conception of language, but this is why I posed the question in the first place: what evidence is there supporting one side over the other
Mar 15	comment	Any attempts at testing or modeling the 'cognitive conception' of language? @hippietrail yup; fixed
Oct 2	comment	'Model-free' learning in humans Thanks Chuck! I agree that the question in the current form is answered via CHCH's article. Possible next steps: 1.Delete question and wait to post the inevitable follow up question. 2. I could Community Wiki it and then answer with a blurb from the article (unless CHCH wants to for the credit) 3. I could (as soon as properly formulated) modify the question to something more in depth since the terminology question was so easily answered. I'd prefer option 2, but I thought I'd ask as maybe the community has some procedure that people have agreed upon.
Oct 2	comment	'Model-free' learning in humans Sorry about the google miss -- this was question I rediscovered from a few years ago. I should've regoogled before posting, but I didn't realize that something would have changed in a couple years. Sorry for the mishap. However, I don't understand how this isn't a question. What part could use rewording?
Jun 20	comment	What form might Jungian archetypes take in the brain? Interesting answer; sounds very well informed on Jung. However, I think the term "sparse representation" is being misused here. "Grandmother cells" are synonymous with local representations. Sparse representations are still distributed; they just tend have most of their units inactive at any given instant.
Jun 14	comment	What form might Jungian archetypes take in the brain? Perhaps I'm missing something, but it strikes me as very odd to presuppose that archetypes have a direct sensory representation. Jung's archetypes were very abstract, high level concepts, so I'd venture to guess that they'd be stored in brain regions associated with semantic cognition. Just a guess though, as I haven't heard anything in the recent literature on any Jungian constructs.
Apr 27	comment	How to get rid of subvocalization? I agree, and vaguely remember speed reading tricks of this sort as being debunked. I'll try and look up some citations if I get a chance.
