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

@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.
