Another thing that only just occurred to me now: These questionnaire scores (VVIQ and MEQ) are supposedly transformed into percentages, but they have values >100...

Ahem... While on the topic of #aphantasia & #mentalimagery: This preprint reports correlations between questionnaires & some measure of hippocampal asymmetry that explain 90-100% of variance. Whenever I see data like this, I'd immediately suspect a bug in the code. doi.org/10.31234/osf...

I agree up to a point. Even with the "I literally see things before my eyes" responses we get in our survey I remain unsure if that's really what people mean. Although I'd also say that the duck-rabbit -is- an experience in eyes, while my mental image is in my head. So not sure about any of it.

The problem with this design is that it isn't an objective test of perception (and in fact their other work on this shows that this is about criterion shifts). But objective tests of perception may fail because they ruin the whole experience (I know because I've tried - but we keep trying...)

🤣

Yes this is the part I am always stumbling over as well. This is particularly a problem for all the so-called "objective" measures (which aren't objective). If we define them by using VVIQ or whatever self-report scores, then surely they are measures of those scores but not necessarily of imagery.

The whole problem with this entire field of research summarised in 216 characters! 😀
