New (i.e. finally published!) paper alert 🥳:
We asked whether unpredicted visual movement feedback is processed differently depending on whether it is behaviourally relevant or not.

Just received some challenging but wonderfully constructive peer reviews that will really help the paper (well, we'll see I guess). SHOUT OUT to all reviewers who still dedicate time and effort to evaluate research in such depth! ✊

There was, however, one region that *did* show different responses to delays depending on their behavioural relevance: the cerebellum. A nice support for its key role in adaptation as suggested by many others!

Jakub Limanowski @jlimanowski.bsky.social · 16d

But, lo and behold, the usual suspects (i.e. temporoparietal and premotor cortices) responded strongly to delays—independently of behavioural relevance. Maybe visuomotor comparison is a basic process of self-other distinction that is not affected (much) by task demands!

Jakub Limanowski @jlimanowski.bsky.social · 16d

We replicated key activations of posterior parietal, extrastriate, and cerebellar areas by visuomotor adaptation. The nice thing is: We show these activations compared with exposition to identical visual delays and movements, but in the absence of attempted adaptation.

So, we used an fMRI-VR visuomotor adaptation task with frequent changes in visual feedback delays. BUT half of the time, participants had to ignore the visual feedback (no adaptation).

Awesome, congratulations!

Jakub Limanowski @jlimanowski.bsky.social · Aug 22

Yes, absolutely, good point! Several studies come to my mind here, e.g. academic.oup.com/scan/article...

Brief snapshop on cortical candidates for visuomotor based self-other distinction. This is stuck in peer review limbo since a while - but I'd be happy for more immediate feedback/thoughts!

AND: violations of visual kinematic invariants in spatially displaced feedback can be detected during observation (as in previous work e.g. by @royesal.bsky.social); but that even here, action enhances sensitivity through visuomotor comparisons.

Jakub Limanowski @jlimanowski.bsky.social · Jun 25

We show that perception overall benefits from action (i.e., visuomotor comparisons); especially for delayed feedback.

Jakub Limanowski @jlimanowski.bsky.social · Jun 25

So the key difference was in whether or not visual and motor kinematics corresponded; and using the elliptical shape, we expected participants to produce systematic variations in velocity - and be sensitive when visual feedback violated those.

Jakub Limanowski @jlimanowski.bsky.social · Jun 25

There's some neat bits to our design (we believe), such as that delayed and displaced feedback followed the same (elliptical) trajectory as the executed movement; and that it was matched in terms of overall spatial deviation.

Jakub Limanowski @jlimanowski.bsky.social · Jun 25

🚨🥳 New lab preprint! In this #preregistered study, we used an elliptical movement task to study perceptual sensitivity to well-matched spatial vs temporal visual feedback perturbations (during action vs observation).
