1/8 Paper! Using previously published data from 270 participants, we look at precision of reaches and hand proprioception in rotation adaptation:
doi.org/10.1186/s13064-026-0…
7/8 Proprioceptive recalibration can't be predicted either. But reach aftereffects can be! Both by precision of hand localization and by the level of proprioceptive recalibration. These predictors are independent, hinting at two ways proprioception guides implicit adaptation.
ALT This graph shows 4 scatter plots. At the top it shows how well active as well as passive localization can predict implicit reach aftereffects, and at the bottom it shows how well a combination of variance and shift of localization can predict reach aftereffects for both active and passive reach aftereffects. The R^2 for using localization shift are 0.24 and 0.20, and when adding the standard deviation of baseline localization this increases to 0.28 and 0.29 for active and passive localization respectively.
Also today at #NCMPan25 is Mireille Broucke's poster 1-G-90 where she's looking at applying new advances in control theory to motor adaptation, and we designed a new paradigm to try to probe the mechanism.
There's a preview of the poster here: deniseh.lab.yorku.ca/files/2…
But we're still working on the project, so some interaction and feedback is very welcome!
Other people working on this project: Jean-Jacques Orban de Xivry, @Henrique5Denise and Gaurav Sharma.
Copied over from BlueSky: @Henrique5Denise is presenting her poster today & tomorrow at #NCMpan25, 1-F-75 where we use Single-Trial-Learning to look at initial implicit adaptation in a variety of situations.
Copied over from blue sky:
Shanaa @modchalingam published the last paper from his PhD projects in Journal of Neurophysiology!
In this paper, he used immersive virtual reality to examine motor memory formation and motor adaptation with more natural perturbations.

The decay rate was independent of the visual cue of surface slant. This means that the visual properties of action consequences, and not external cues, enabled formation of context-specific motor memories.

There are more conditions tested in the paper here: doi.org/10.1152/jn.00268.202… And we'd welcome feedback and comments!

Finally out, our paper on additivity of measures of implicit and explicit adaptation. I'll describe it on blue sky, and will be happy to discuss there as well.
