comment Why is it common for people to default to a single causal source to explain new phenomena?
@Comptrol no i think there's a valid question in here, but I think the phenomenon is much more general than you give it credit for. Research on causal reasoning tends to show that once people attribute a cause to an event, they tend to discount other possible causes. So the question then becomes, why do conspiracy nuts think X is the most likely cause?

comment Why aren't sleep measures consistently measured as mediators/moderators of cognitive performance?
Yes, I agree with almost everything you say; I think I just did a poor job of wording my argument. I'll try to edit my post to be more clear, but you bring up some good points as well-- maybe you should delete your comments and turn them into an answer?

comment Why aren't sleep measures consistently measured as mediators/moderators of cognitive performance?
@Preece no. as an example, let's suppose i put a test online to collect data from any participant who is willing. those who take the test voluntarily likely share certain characteristics-- perhaps they are more inquisitive than the population as a whole. in this case my sample is biased, because inquisitiveness is not normally distributed in my sample with respect to the population.

comment How can I create computer based psychology experiments using OS X?
To note: PsychoPy doesn't require you to write code from scratch, but its capabilities are greatly expanded by doing so. (Disclosure: I haven't actually used it).

comment Do we understand the non-subjective mechanisms behind pleasure and pain?
@rob they actually contain 'logic', as you say. if they simply responded to hedonic stimuli, they would not respond to a CS. And indeed, this logic codes for 'future behavior': studies show that firing dopamine neurons do not simply reflect the current value of the stimulus, but the discounted sum of all future values. Wikipedia TD-learning for more info.

comment When is higher confidence predictive of less accuracy?
@JeromyAnglim that was my first thought too (re: ceiling effects, regression to the mean), though they discuss this in attempt to rule out that explanation. i think there's still some room for debate, but it does have 1000+ citations, so a lot of people seem to buy into it, for whatever that's worth.

comment What is the term for when too many choices results in inability to decide?
+1, also known as "choice overload". william is right, though, that the original results may be overblown. see a meta-analysis @ scheibehenne.de/ScheibehenneGreifenederTodd2010.pdf

comment How can I find open access journals for cognitive science research?
@Steven probably for the best, but i still contend that the number of reputable open-access cogsci journals is very small. i would be surprised if more than a tiny fraction of the journals listed on DOAJ (Psychology) have an impact factor > 1.
