Involuntary feedback responses reflect a representation of partner actions We have a remarkable ability to seamlessly and rapidly coordinate actions with others, from double dutch to dancing. Humans use high-level partner representations to jointly control voluntary actions,...

Thanks, Toby!

Online Movements Reflect Ongoing Deliberation From navigating a crowded hallway to skiing down a treacherous hill, humans are constantly making decisions while moving. Insightful past work has provided a glimpse of decision deliberation at the mo...

This project was a lot of fun to work on with a great team, including Jan Calalo, Truc Ngo, Seth Sullivan, John Buggeln, RakLokesh, Adam Roth, Mike Carter, Isaac Kurtzer, and ‪@joshcashaback.bsky.social

Finally, we were also able to provide an alternative interpretation of previous reaching behaviour in the literature by using our decision-making and movement model.

We also found that considering both evidence accumulation and urgency (Trueblood model) was essential to explaining decision times.

Across several experiments and computational modelling, we show that ongoing deliberation influences the online control of movement---following movement onset and prior to a decision.

Past work in has provided brief snapshots of the deliberation process at movement onset (go-before-you-know paradigm) or the influence of a decision itself during movement (changes-of-mind). Yet it is unclear whether ongoing deliberation is expressed during online movement.

We are excited to share our new paper that dives into how ongoing decision deliberation reflects ongoing movements: (jneurosci.org/content/45/3...
A tour-de-force by the incredible Jan Calalo.

Need to get a cool animal model and just repeat all the classics.

Sounds like it is bouncing back. Happy to hear!

dynamical systems movement theories, specifically.

Movement models issues in the 1990s reappearing in neural models in the 2020s

Neural space has very similar issues to the behavioural models in the 1990s (e.g., dimensionality reduction, dynamical systems theory/attractors), which are more observational than mechanistic.

Just finished a very detailed read. Fantastic paper! If you haven't read it yet, you should!

you made "the list"

Interference between flexible and adaptive reaching control Humans rapidly update the control of an ongoing movement following changes in contextual parameters. This involves adjusting the controller to exploit redundancy in the movement goal, such as when rea...

When we reach for an object, we adapt to unexpected dynamics and respond to disturbances. These two mechanisms work online, and when you perturb them at the right time, you can see interference...

Not sure if this is helpful but one little thing that I did was have my gutters repitched to the other side of the house where we had a downslope.

I had to deal with water coming into the basement. Are you downhill / have property sloping towards the house?
