comment Can lucid dreaming detract from the recuperative effect of REM sleep?
@draks... '@Artem i posted the link because i thought it provided an answer to your question, but this is not my area of expertise. if one of you wants to paraphrase the answer on quora or do some more research, that would be great, but i don't have time for it at the moment

comment In SDT, how is an increase in detection sensitivity conceptualised in terms of the movement of the distributions?
it's worth noting that one can also represent an increase in sensitivity as a decrease in the standard deviation of the distributions

comment Are there any free databases of audio-visual emotional stimuli (English)?
duplicate? or are you specifically looking for stimuli that are audio AND visual, rather than audio OR visual?

agreed, this should definitely be a first step before "correcting" the "problem"

comment How to use Mechanical Turk for longer studies (i.e., 30 minutes+)?
There are no real restrictions on what you can do for an mturk study; all experiment code can be hosted and run on your own servers.

comment Analyzing control questions data for a survey
As for the issue of satisficing, I'm simply answering the OP's question. He is concerned about it, and other researchers have voiced concerns as well. I never claimed that it was a widespread problem, but it appears to be a problem in at least some circumstances.

comment Analyzing control questions data for a survey
@GaëlLaurans I am not suggesting the use of Cronbach's alpha here. I mentioned it because it seems like that's the solution OP was trying to employ, but as I said in my post it is inappropriate here. As for the Facebook example-- don't take it too literally. I'm promoting the general idea behind an IMC, and not advocating for a specific implementation. There are probably more effective examples.

comment What is the maximum number of objects an average human being can recognize at once?
also remember that if you can subitize 4 items, counting to 5-6 will only tack on about 250-500ms, a very short amount of time. so i think it's difficult to establish whether you're counting or subitizing without using more controlled chronometry

comment What is the maximum number of objects an average human being can recognize at once?
@what the average is about 4, but there is definitely a range. you may be on the high end of the spectrum. there are two other alternatives i can think of: for eggs in a carton, you may simply be recognizing specific spatial patterns and associating them with numeric quantities. similarly for apples or other objects, perhaps you're using total spatial area as a proxy for quantity. these are not really subitizing, as they are domain-specific and rely on expertise.

comment Math or Physics: Which is the more relevant background to enter Cognitive Sciences and Psychology?
+1 there's also a good amount of physics involved in some methodologies, like the physics of how fMRI work (NMR)

comment Computational Neuroscience software
As is, this question is overly broad and open-ended. Please consider editing your question to be more focused and address a problem that you face, rather than simply a discussion.

comment How to design research participant recruitment flyer to maximise participant response?
IMO this is a little too open-ended and "discussion-y"; unless of course there an empirical paper on which techniques are most effective! also, it's not very specific to cogsci-- lots of disciplines post recruitment fliers. perhaps a question better asked in chat...

comment What is the status of evolutionary psychology in academia today?
Interesting, but note that OP is asking about the status of evolutionary psychology today, not in 1981. I suppose what you're saying is that these articles commonly appear on social psych syllabi today?

comment Deception and nose touching - does it work for things that are about to be said in prepared speeches?
@AlexStone I'm not sure either, but it seems like something we need to confirm before we're able to answer the main portion of your question...

comment Does higher Electronic use relate to lower memory
Hi elder4222, this is an interesting question but it has been asked before! (see this question). I have flagged to close as duplicate.

comment Inducing Auditory-to-Visual Synesthesia
also, could you possibly cite or provide a link to the original video if possible? it could help us figure out if a) your interpretation is simply incorrect or b) the claim isn't really a scientific one, etc.

comment Inducing Auditory-to-Visual Synesthesia
i understand. my concern is that 'synesthesia' is a neurological conditions, and so it is impossible to 'induce synesthesia' by virtue of its definition (short of rewiring the cortex...). Perhaps just changing it to 'synesthesia-like symptoms' would suffice, or maybe someone else has a better suggestion

comment Inducing Auditory-to-Visual Synesthesia
I have edited this question because I don't believe this qualifies as synesthesia. Let me know if you think I've altered the meaning of your question.
