Preprint: Frame Effects Across Time and Space (FEAST): www.biorxiv.org/cgi/content/...
In the frame effect people perceive a large horizontal separation between two horizontally aligned flashed probes when they are flashed within a left-right moving frame.

Frame Effects Across Space and Time
When two probes are flashed at different times within a moving frame they can be perceived as dramatically separated from each other even though they are at the same location in the display. This effe...

In this paper, Andrew King looked at tools as cues for dual adaptation. He used a VR task, where a ball had to be launched to a target with a 30 degree rotation.

In this paper we use a new approach from control theory (engineering), a "disturbance observer", to see if it can be applied to visuomotor adaptation. This "DO model" is doing reasonably well.

In this study @deniseyph.bsky.social and I take data from 4 previous studies, and their pilots, with N=270 to look into potential relationships between precision of reaching directions and proprioception and various other measures.

Because if I wanted someone to confidently make up answers to my questions I would simply ask a man
Bit of an odd story this one - the main analysis says women don't use AI because they lack STEM skills, confidence and value in the workplace. Yet the anecdotes suggest that women excel at communication, whether writing or interpersonal, and can spot ChatGPT's flaws

Why are fewer women using AI than men?
The use of artificial intelligence appears to have a significant gender imbalance.

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. @ncmsociety.bsky.social

Hi, We have new open positions – PhD student and postdocs– experimental or computational– in our research groups at @nerflabs.bsky.social in Leuven Belgium on neural circuit basis of visual behavior/developmental disorders. I am at Cosyne Workshops and happy to discuss opportunities.

Shanaa (not on blue sky) 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.
