In our latest study, we describe a novel relationship between action planning and working memory. Our results show that action-item associations affect how working memory maintains the fidelity of sensory information during a task.

Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...
Concurrent selection of internal goals and external sensations during visual search
Internal and external selection processes can codevelop in time to yield efficient search behavior.

Any early-career researchers in #workingmemory wanting to contribute to an #openscience initiative? I'm looking for help building up a data hub resource for the field. Volunteers can expect to devote a few hours, and might pick up insights into handling research data and how to use Github.

New preprint!
Working memory contents can be decoded from alpha band power. But does working memory maintenance really depend on these oscillations?
We say no, because we found that alpha power decoding only works for prioritized items, not deprioritized ones. 1/3
