Why am I writing this?
I've been active on the Stack Exchange (SE) network for over a year on a wide variety of different sit...
" Larsen et al. obtained evidence that a word whose first letters are more distorted than later letters are harder to read. As a resulting guideline they state "if only one side of a virtual environment is to be used for presenting text, the left wall is preferred"."
In cognitive linguistics, conceptual metaphor, or cognitive metaphor, refers to the understanding of one idea, or conceptual domain, in terms of another, for example, understanding quantity in terms of directionality (e.g. "prices are rising"). A conceptual domain can be any coherent organization of human experience. The regularity with which different languages employ the same metaphors, which often appear to be perceptually based, has led to the hypothesis that the mapping between conceptual domains corresponds to neural mappings in the brain.
This idea, and a detailed examination of t...
" Conceptual metaphors shape not just our communication, but also shape the way we think and act." ... damn this stuff is gold for my thesis. ;)
As I'm following the conceptual metaphor of time in the distance ... and now being nearer.
Just my opinion, but I think that while this question is far from perfect and makes a number of assumptions, that I could give a meaningful answer that discusses those assumptions. Thus, my vote is to re-open. — Jeromy Anglim1 hour ago
I would be fine with it if he's got an answer on tap
Seconding @ChuckSherrington's sentiments, I would only vote to open if the question is edited to reflect the assumption that it is or isn't possible to achieve expertise in two distinct domains. Where is this question coming from? We close questions when they aren't clear, that's standard procedure. If Jeromy invests time in answering assumptions, it might be that those assumptions weren't what the question was about at all. Thus, that's why I closed. — Steven Jeuris7 secs ago
"Psychological research has demonstrated how real or imagined physical motion scenarios can prime construals of time by activating the relevant source domain" (http://www.cogsci.ucsd.edu/~nunez/web/timeaftertimeF+.pdf)
@StevenJeuris it associated too much responsibility with down-voting... which would make it EVEN LESS common.
@StevenJeuris I understand the excitement to close questions quickly, but we are not overwhelmed with questions right now. I think in general, we should try to let the community act to make sure the moderators don't come off as too heavy handed. This is especially important in light of @JeromyAnglim's comments for the potential usefulness of the question
Of course, I would have voted to close currently, and agree with the decision, I just think it should have been left to the community.
@jonsca that would be very poor use of mod-powers, especially since the question had two community close votes. That is one downside to being a mod: you have to cast virtual close and open votes. There should be a feature that allows mods to cast non-binding close/reopen votes
@jonsca Partially due to the accounting, but that's fine :D We are doing great! We just need to make sure to keep the momentum through out June. Don't let our confidence undermine our determination... don't want to pull an Italy
Activity has an hierarchical structure, and can be analyzed at different levels: activities, actions and operations. (Leontiev 1974)
The top level is activity itself, oriented towards its motive. At a lower level lie conscious goal-directed actions that must be...
I've recently started using my trackball left-handed after being right-handed my whole life. The motivation is partly to balance out wrist strain, and partly to see how much my brain rejects the idea.
Since I am at the computer for a good portion of the day, this is a fundamental change. I start...
This issue is something I have noticed with myself, people in my surroundings and random people on the internet. Their lives are perfectly fine, but yet they feel depressed. In my specific case it's a feeling that lasts for a few days typically and then magically disappears. Only to reappear a co...
That was the first time I saw such a video and it totally blew my mind... especially when the girl could COUNT the coins and still was fooled. Or when she SAW her cracker being broken in half and still decided it was fair
I've never taken a dev-psych course though (or even psych 101) so I was not exposed to these cute videos earlier
Anywho, must run. Pleasant chatting with you gentlemen. Cheers!
According to Shall we have MathJax?, to enable MathJax would require a demonstrable need.
How can we demonstrate this need? Perhaps by creating a CW list of questions that would benefit from proper notation?
To what extent is this a catch-22, in that the absence of MathJax restricts the ability...

> An alternate theory was posited in the 1960s, when scientists conducted experiments in a search for molecules responsible for memory. In one experiment, rats, normally nocturnal animals, were conditioned to fear the dark and a substance called "scotophobin" was supposedly extracted from the rats' brains; this substance was claimed to be responsible for remembering this fear. Subsequently these findings were debunked
Classic thinking, fear of the dark must be a magic substance
This might be one the dirtiest questions I've written @jonsca can you give me your expert bio.SE opinion:
> I frequently use the fittest-win model of selection as a first approximation. Where the probability for a mutant of fitness r to invade a host population of fitness 1 is 100% if r > 1 and 0 otherwise. I also use the Moran process model for finite populations, or take its limit as n goes to infinity.
> In general I am interested in simple models of selection of a single (or small concentration of) mutant invading a host population of fitness 1, with fitness independent of frequency. Are there other mathematical models of selection of this type?
@StevenJeuris Just sounds like consistency, wouldn't call it top down processing. If something is always important and deserves easy access, keeping it "on top" makes logical sense. There are some gestalt principles to be aware of if you're trying to make it's position make logical sense though
When modeling selective sweeps as a micro-building block in models of macroevolution (not to be confused with misuses of this in creationist arguments), I use the fittest-win model of selection as a first approximation, or Moran process model when I want a more reasonable approximation.

Dickinson (2005) has a good review of insect flight, including behavior, biomechanics, electrophysiology, and neural control with links to more of the primary literature. What follows is a general summary thereof.
The jagged trajectories you mention are called saccades in the insect flight liter...
It could be adapted into a flippant answer here on cogsci, to this question:
Can asaccadia (i.e., lack of saccades, due to neuronal or muscular damage) be overcome? Do other muscles (e.g., neck) compensate? Are the resulting gaze patterns the same as for saccades, and are they involuntary the way saccades are?
Conversely, in normal vision, is the saccade-fixation system ...
@BenBrocka "Minimizing information access cost. When the user’s attention is diverted from one location to another to access necessary information, there is an associated cost in time or effort. A display design should minimize this cost by allowing for frequently accessed sources to be located at the nearest possible position. However, adequate legibility should not be sacrificed to reduce this cost."
Is there any evolutionary advantage to finding melodies or harmonies pleasurable? Does the ear pick up these particular oscillating waves differently from other sounds, and if so, how does that affect our perception of pleasure? I'm looking for some sort of signalling pathway (most likely involvi...
fMRI studies yes, but "does X make people happy" studies?

It's a psychology question with an answer from psychological papers. There's biology involved in psychology of course, but that doesn't make the field a subset of biology
> The part of neuroscience that is ontopic here on Biology.SE is anything related to the molecular basis of neural processes or illnesses. Anything that goes more into the directions of psychology or psychriatry would be off-topic here.

@jonsca Okay, questions that are narrowed down to the location of exact action potentials could be asked on Bio.SE. That question (and the other perception questions I saw) aren't nearly that low level
@BenBrocka Well, I'm still not entirely certain whether I interpret 'top down processing 'correclty. That's why I'm asking. :)
Wikipedia mentions that Christopher Hickens defined it as one of many principles for display design: "Top-down processing. Signals are likely perceived and interpreted in accordance with what is expected based on a user’s past experience. If a signal is presented contrary to the user’s expectation, more physical evidence of that signal may need to be presented to assure that it is understood correctly."
Oh well, I will stick to consistency, so I don't say anything stupid. :)
Hey fellow mods (@JoshGitlin and @StevenJeuris) and @BenBrocka a user deleted this question because I think he concluded it was silly (partially from my comments) but I think it is an answerable question and I have a friend that wants to answer it. Is it inappropriate to undelete the question?
I saw something deeply disturbing today:
A completely sarcastic answer that went right to the heart of the question and eviscerated it with the clean precision of an exacto knife.
But it was deleted by the owner! Presumably because they wanted to be nice -insert eyeroll here-.

I would first like to discuss the concept of lateralization and clear up a common misconception about hemispheric dominance.

For example, there have been numerous studies from Jeffery Schwartz about deactivating different parts of the brain in OCD patients by relabeling actions as they are happening. They find that parts of the brain actually become calm and the repetitive behavior is stopped, when doing this.
Has there been any research proving, disproving, or exploring the concept of conscious activation of specific brain regions?
To elaborate on this:
I've read that performing processing tasks causes the brain to reinforce that type/kind of processing or thinking. For example, visualizing perform...
