comment Performance of a group solving a cognitive task: How does it scale?
@H.Muster My paper (thx, btw) deals with a specific 2AFC task and gives only theoretical predictions (but two of co-authors are now doing experimental part). I'm interested if there is known scaling of efficiency any other low-level tasks (e.g. solving a word puzzle, solving a multiple choice test, signal detection, counting the number of blobs...). I am curious if there are experimental results that either are compatible with my results, or undermine it.

comment Performance of a group solving a cognitive task: How does it scale?
I am aware of that paper, and actually I like it very much (and had nice discussion with an author, and even used it as an example on academia.SE). However, scaling is quadratic/linear, depending on the group size. And discipline changes only critical group size, not the scaling properties (which may be more a subject of social interactions + some hidden factors correlating group size and a measure of performance).

comment Perception of probability of being right
@Speldosa Partly. I know what is signal detection theory; and actually the question was motivated by it. However, here I am not interested here not in the underlying theory but solely in belief that one is right vs real probability that one is right. But thanks for pointing to the paper (Plescak and Busemeyer) as it answers my question for a particular setting.

comment What are the purported mechanisms of eidetic memory and why is it comorbid with autism?
I see. However, it may depend on the definition of savant. The article you are pointing to use it vaguely as 'savant skills'. For me it is possible (but far from obvious in any way) that 'autistic subjects have better visual memory that non-autistic subjects'. Of course, if you compare the relative verbal/visual skills you get you conclusion, but it is very different from the former. When it comes to visual skills of autistic persons, see e.g. aut.sagepub.com/cgi/reprint/11/6/547.pdf.

Bear in mind that savants are extremely rare, also among people with autism. Moreover, a brief look at en.wikipedia.org/wiki/… gives impression, that it is not an 'autistic condition'.
