OpenWMData A collection of publicly available<br>working memory datasets

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.

Sustained alpha oscillations serve attentional prioritization in working memory, not maintenance Recent theory on the neural basis of working memory (WM) has attributed an important role to "activity-silent" mechanisms, suggesting that sustained neural activity might not be essential in the reten...

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

Microsaccades strongly modulate but do not directly cause the EEG N2pc marker of spatial attention Researchers often study human attention using microsaccades and the N2pc EEG marker, but it is unclear to what extent microsaccades contribute to N2pc. This study shows that microsaccades modulate N2p...

The human-neuroscience N2pc marker of covert and internal attention co-occurs with spatial biases in microsaccades, 200-300 ms after prompted to shift attention. (How) are these empirical phenomena related? Check it out in the latest work led by @baiweiliu.bsky.social:

3/4 Our new analyses reveal that this facilitates a bias in WM toward interference (rather than a swap of the target with the interference). And when this happens, we observe a control mechanism at work, evident in frontal theta activity, that mitigates further disruption of WM from this process.

2/4 Our main results provide novel evidence for selective WM gating that depends on motor control. We show that when the main task and the interfering task share motor components, visual WM interacts more strongly with distracting perceptual information.

Now out in JEP:G! We (@fridaprintzlau.bsky.social & @keisukefukuda.bsky.social ) resolve inconsistent attentional protection in WM by addressing discrepancies in cueing. Upshot: Attention changes how perception biases memory, but *not* how memory biases perception!
