comment Extending a 5 point ordinal scale to 9 points while maintaining comparability
Thanks. We're very interested in individual fluctuations over time, and will model measurement error etc, hence the switch to a finer grained scale. We have no scope for giving only some participants the old scale, sadly, though perhaps one group of items using the scale can use the old and another group of items the new, if we separate them within the survey. Comparison with previous research is only interesting in the case that interesting findings come up - so a little catch 22, yes.

comment Differences in willingness to correct errors made between human and computer interactions
Yes. Social desirability covers the general phenomena pretty well. Didn't find anything specifically on error reporting, so I guess that link is for me to make.

comment Controlling for response bias in a forced choice memory task
I ended up running the experiment with the inclusion of unseen items, and will control for the observed response bias across those (as if no bias they should be selected with equal frequency) with an ANCOVA.

True, moving to confidence ratings rather than yes / no would allow exclusion of guesses. I'd be worried about excluding too many with only the suggested four options, but I agree something along those lines should work.

comment How to assess participant awareness of experimental deception without inducing awareness?
Yes, the inclusion of a question that's innocuous when the answer would be 'no' but still clear when the answer would be 'yes' is a great idea. I'm not sure whether I can pull it off for mine, but will try.

ok, cheers, though I still can't find much info, as you suggest... is the 'funnel', starting with vague questions, thought to minimise demand characteristics from the final direct question?

it's related to change blindness yes, and I am going through that literature - but this is a broader problem than that, 'how to ask someone something without them being informed by the question'. Quite possibly a hopeless task, I realise, but I wanted to see if anyone had further ideas.

essentially: there is an image of a scene with items in it, the scene is then altered somewhat, I want to attain most accurate reports of noticed alteration with minimal provocation of the noticing.
