comment Is it possible to objectively measure the amount of pleasure a person is experiencing?
You can get pretty far just by asking people how much fun they're having.

comment Which study design to use: nested case-control or case-cohort?
Just to make sure I understand your descriptions correctly, the only difference is that in the first case we control for age and comorbities as part of the study design by sampling in a particular way, while in the second case we sample randomly and then control for age and comorbidities statistically (as I assume you would)-- correct?

comment What areas of mathematics support the study of cognitive science?
This answer would be even more useful if, for each of the subjects you listed, you could give even just very brief examples of areas in cognitive science that would draw on these mathematical topics to some extent.

I can't parse the first sentence in this question. What does it mean?

comment Aesthetic preference for even or odd numbers
I agree with zergylord, the answer to this depends on what you mean by "prefer." My best guess is that you mean that when people give quantitative estimates of various quantities, the stated estimates are more likely to be even numbers or numbers divisible by 5 compared to other numbers. But you need to confirm whether this is what you mean.

comment When can anchoring backfire?
I am very unclear about how the percentage accuracy rate statistic that you report is being computed. Is each estimate classified as either "accurate" or "inaccurate" and the accurate rate is the proportion of "accurate" estimates across people? What are the criteria for classifying estimates as accurate or inaccurate? Or is this "average accuracy rate" constructed in some entirely different way? If so, how?

comment Is there a database of emotional stimuli available?
Note to the OP that this lab also a database of "emotional sounds" that you can request (International Affective Digital Sounds; IADS). I have used IAPS extensively but have never really looked at the IADS and so can't make any comments about how useful it is.

comment What stimulus features determine the psychophysical power law exponent?
I am moving this discussion over to the Cognitive Sciences chat room ("The Axon Terminal").

comment What stimulus features determine the psychophysical power law exponent?
Okay, so then maybe the reason I can't find any discussion in the psychophysics literature about the questions I raised in the OP is because it is just implicitly and universally understood among psychophysicists that you Don't Ask That, for the reasons that you point out concerning units. If this is the case then I guess my question is answered.

comment What stimulus features determine the psychophysical power law exponent?
The point about units is simple enough and I'm not questioning it. My request is whether you are aware of papers specifically from psychophysics, or psychology more generally, that bring up these dimensional issues in response to the psychophysics work from the OP. It is clear that table and figures like those I posted above invite comparisons in the exponents across stimuli. So if it is the case that such comparisons truly are of little or no warrant, then I would expect people to have made this basic point in writing somewhere in the psychophysics literature. Do you see what I mean?

Thanks for the information Piotr. Do you have any citations/references to papers that have considered the issues that you discussed?

comment What stimulus features determine the psychophysical power law exponent?
Thanks for the comment; I welcome speculation. I am aware of some of the criticisms of the evidence for universal power functions, but just to be clear to other readers: I would prefer not to have this thread veer off into that discussion if it can be helped. Whether the most accurate psychophysical function is actually power, log, exponential, or whatever, the important point for the purposes of this thread is just that some types of stimuli are characterized by more quickly increasing slopes than others, and I am interested in the stimulus factors that influence this variability.

comment What is the term for judging based on a simulation of the same parameters on oneself
My first thought after reading the title was that it related to the literature on egocentric judgment, but after reading the full question, it seems to be more about moral judgments in particular, which that literature has not focused on as much. Is it accurate to say that what you are interested in is judgments from the moral domain?

comment How to assess participant awareness of experimental deception without inducing awareness?
Also, people sometimes use these procedures to probe separately for awareness of the manipulation vs. awareness of the experimental hypothesis, in cases where the distinction is potentially of importance (like in some learning research).

comment How to assess participant awareness of experimental deception without inducing awareness?
Sort of. Part of the idea is that if a participant never spontaneously mentions the thing you're probing for until you ask about it point-blank, it may be more safe to assume that they didn't really notice it or at least didn't think much of it. On the other hand, indicating it on one of the first couple of questions would be a big red flag.

comment What are some of the drawbacks to probabilistic models of cognition?
This isn't really a proper answer, but you may find informative the following BBS paper criticizing Bayesian models of cognition: Jones M., Love B. (2011). Bayesian fundamentalism or enlightenment? On the explanatory status and theoretical contributions of Bayesian models of cognition. Behav. Brain Sci. 34, 169–188.
