New review/theory paper out with Julie Bugg, Chris Nuno, and Changrun Huang. The upshot is that we don’t know for certain why it’s so hard to get people to engage proactive control from trial to trial (but it’s fun to think about it and speculate!).

Our recent review led by Julie Bugg is out in PB&R. We explore why advance warnings to pay attention often fail to improve proactive cognitive control in conflict tasks. We introduce the TEPID framework to explain this. link.springer.com/epdf/10.3758...

Excited to share this work! The consistent lack of cue-driven proactive control challenges assumptions about our ability to readily deploy top-down control. We rule out S-R mappings, task pace and task difficulty as explanations, while showing that implicit, experience-driven control remains intact.

New paper from the lab now out online! @changrun-huang.bsky.social asked whether people use informative pre-cues to up-regulate cognitive control in the spatial Stroop task. Surprisingly, they do not, and we rule out some possible reasons why. Enjoy!

We put out this preprint a couple months ago, but I really wanted to replicate our findings before we went to publication. At first, what we found was very confusing! But when we dug in, it revealed a fascinating neural strategy for how we switch between tasks doi.org/10.1101/2024.09.29.615736 🧵

Convergent neural dynamical systems for task control in artificial networks and human brains

The ability to switch between tasks is a core component of human intelligence, yet a mechanistic understanding of this capacity has remained elusive. Long-standing debates over how task switching is i...

🎉New project 🎉 doi.org/10.1101/2024... How do we navigate between brain states when we switch tasks? Are dynamics driven by control, or passive decay of the prev task? We shed light on this classic debate by comparing high-d linear dynamical systems fit to EEGs and RNNs during task-switching 🌀
