Takeaways: musicians better in SJ tasks (but may be response bias) yet show > multisensory integration in a more objective RT task (but may be just better sustained attention, motivation, etc.). SJs show rapid recalibration but RTs don't, so RR probs not due to early sensory latency changes 9/10

Ah, yes, that makes sense. An apt description, then. A lot of people also see the two dots as appearing semi-transparent (even in the conditions where they fully opaque, I mean), which might contribute to the effect you're describing.

Hmm... I'm not sure what you mean exactly. Are you saying the frames double too? The common reported experience is that only the dots "split", there is no illusory effects w/r/t the frames.

About 10-15% of people never saw the illusion in our experiment's viewing conditions so there may just be some intractable individual differences. I have always been very susceptible to this illusion so it's been hard to relate 😅

Most people report seeing two distinct dots either side-by-side or with some diagonality - typically with the dot on the left being lower and the right being higher. People also sometimes reported seeing "oblongs" or "rectangles" which we assumed to mean there was partial separation.

Thanks for saying! We played around with initial demo *a lot* to try and maximise the effect. We found lots of individual difference, but most see it inconsistently. It's an open question as to what produces the inconsistency. We posit something attentional although there's prob. multiple factors.

Hello Prof Miller. Bluesky didn't support uploading mp4 files when I originally posted, but it does now:

This illusion has a number of unique properties when compared to other motion illusions, but we also argue, using a predictive processing framework, that it has important implications for how the brain constructs visual experience in space and time more generally. [4/5]

In our illusion, we used two overlapping frames moving symmetrically and transparently. When a stimulus was flashed within the two frames as they both reversed direction, two concurrent mislocalisations can be perceived. [3/5]

The illusion was inspired by Özkan et al.'s (2021) paradoxical stabilisation of moving frames, where the position of a flashed stimulus is misperceived due to the motion signals from a surrounding frame as it reverses direction. [2/5] www.pnas.org/doi/10.1073/...
