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.

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.
