comment How does the brain read rotated text?
This is a very nice answer. I'd like to add that we probably first need to learn that the orientation of a letter matters in the first place (i.e. it can be a different letter if seen from a different orientation, like p and d). With all other objects, their identity remains the same no matter from what angle we see them from.

comment Which are the most accredited tests for measuring personality traits?
I think this is an OK question! I even had a similar exam question as a student for my personality psychology course: "Why big 5 instead of big 3 or small 16?" (i.e. Costa&McCrae vs. Eysenck vs. Spearman).

comment What do we call the “middle” variables in a complex research model?
@caseyr547 - that's weird, I never saw your answer.

comment What do we call the “middle” variables in a complex research model?
To add to what I wrote above: I think the key issue is where the question is most likely to get the most or the best responses.

comment What do we call the “middle” variables in a complex research model?
@caseyr547 - I really don't mind where it ends up. It looked like a familiar problem to me because of my educational background, which is in psych / cogsci, that's all. We certainly learn a whole bunch about experimental designs and stats, models with multiple levels of dependence on each other, etc.

comment What do we call the “middle” variables in a complex research model?
@caseyr547 - mostly because this methodological issue has been discussed a lot in social and personality psychology.

comment Why do long range axons in mammals travel in white matter tracts?
Very interesting indeed! Let me speculate: a lot of neighbouring neurons from one area will need to connect to neighbouring neurons in the next area in a processing stream. If they all follow the shortest path, they will end up in a bundle.

comment Are “dumb product warning labels” an indicator of change of intelligence of general public?
To claim that IQ might be dropping because of something, you first have to ascertain that it is in fact dropping. But, as you already say, according to research, it's rising. So, no, it's not dropping because of the labels, because it's not dropping.

comment Innate personality tests: do they exist? If not, why?
That's definitely true. But if you want to examine personality, you have to start from looking at how people behave, or feel, or think, and these are already influenced by a combination of genes and environment. Scientists are looking for genes as well, but it seems that personality traits are the outcome of many mutually interacting genes, rather than just a few, like eyes. So in the end it's hard to say anything about any of the individual genes present in this massive interaction.

comment Innate personality tests: do they exist? If not, why?
You seem to think that innate and environmental effects have independent influences on personality, i.e. that they don't interact. How come?

comment What are “linear spatial weightings” and “specific temporal windows” in Philiastides & Sajda (2006)?
@NickStauner - I wish I knew the answer though! I've never done pattern classification myself (it's on my to-do list for this semester!). I do know that the psychometric function refers to the data itself, and not to something the algorithm does.

comment Significant baseline, Oddball paradigm
@Mathilde - oh and by the way, of all the things I suggested, I would first try removing standards preceded by deviants. It's a much cleaner comparison that way in any case.

comment Significant baseline, Oddball paradigm
Hi @Mathilde, of course you can :) If you google me and the institute where I work (you can find my web page in my profile if you click on my name), you can also find my e-mail address and contact me directly if you prefer. But I do read this board regularly, so it's safe to ask further questions here as well.

comment Learned dyslexia? adult predicament from childhood teacher´s incompetence?
I really can't say, as I come from a country where dyslexia is not such a well known issue. I do however live with someone who is brilliant yet reads with considerably more difficulty than myself, and I can see how it can be hindering... yet it's clearly unrelated to intellectual ability.

comment Learned dyslexia? adult predicament from childhood teacher´s incompetence?
There are ways to deal with dyslexia if it's real (and it seems to be, though self-confidence can of course be a real issue as well): special fonts, careful spacing between letters, certain filters to put on top of the page... Maybe those are some avenues worth exploring?

@Tanner - just updated the second link, it now leads to a pdf which is on NYU's server.

Glad you like it :) And thanks for adding information about where to get the pdf. I hadn't realized that both my links are behind paywalls until now.

comment Which physical properties of a stimulus can a human attend to?
I recently came across a paper on higher-order statistical properties of waveform processing which seems relevant to your question. I'll look it up as soon as I find the time!

comment Why do humans' eyes enter an unfocused gaze when recalling a memory or imagining something?
It also happens when people are trying to solve a mental problem (like doing arithmetic in the head), not just when they're memorizing something. I've read that most people will look upwards and to the left when doing this, but I don't know about the neurophysiological reasons behind it.

comment Does initial 0-3 years of age have any effects for a permanent bonding to happen between the parents and their children?
I also thought about attachment styles when I read the question. However, I'm not so sure they apply here so well. An attachment style refers to a prototypical style of forming relationships with all significant people in one's life. If the brother is detached from everybody, then it makes sense to say it's an attachment issue. But if it's just the parents, I would guess it's probably not.
