New paper out on value-based prioritization in visual WM. We used hDDM to account for speed/accuracy tradeoffs and isolate memory benefits from perceptual/motor benefits. We see perceptual/motor contributions suggesting that prioritization benefits are not purely mnemonic.

Reward-based prioritization in working memory is distinct from recency and due to a resource trade-off

Although the reporting requirements are over for basic experimental studies in humans, the principle of making research plans and results public and accessible is “a good one that we should all continue to work on,” Jeremy Wolfe says.

New preprint with @SamJung @timbrady.bsky.social and @violastoermer.bsky.social: osf.io/preprints/ps.... Here we uncover what might be driving the “meaningfulness benefit” in visual working memory. Studies show that real objects are remembered better in VWM tasks than abstract stimuli. But why? 1/

As a synthesis of my PhD research, we revisited the prevailing assumption about the mechanisms underlying repetition learning, and re-evaluated these assumption in light of recent findings.

This was such a joy!!! In this work, the brilliant @fridaprintzlau.bsky.social demonstrates the core features of VWM representations, namely its dynamicity and flexibility. TLDR: VWM dynamically shifts its representational geometry during maintenance depending on its task demand! What an ART!

"Repetitions lead to better memory." Sure - but how? Our new paper led by former lab member @philippmusfeld.bsky.social shines new light on this question, and challenges some longstanding assumptions. Now published in Perspectives on Psychological Science.

🎉 My first first-author paper was just accepted in JEP:HPP! We asked what “active” vs “passive” WM states do - do they protect against interference? Across 4 behavioural experiments we find no reliable protection. Updated preprint here: doi.org/10.1101/2024.02.05.578913 @elkanakyurek.bsky.social
Feature and space-based interference with functionally active and passive items in working memory
Functionally active and passive states in working memory have been related to different neural mechanisms. Memoranda in active states might be maintained by persistent neural firing, whereas memoranda in passive states might be maintained through short-term synaptic plasticity. We reasoned that this might make these items differentially susceptible to interference during maintenance, in particular that passively maintained items might be more robust. To test this hypothesis, we gave our participants a working memory task in which one item was prioritised (active) by always probing it first, while the other item was deprioritised (passive) by always probing it second. In two experiments, on half the trials, we presented an interfering task during memory maintenance, in which the stimuli matched either the feature dimension of the memory items (colour or orientation), or their spatial location. Whether the interfering task appeared on a given trial was unpredictable. In a third experiment where participants were given prior knowledge of the interference condition, and finally in a fourth experiment we used a reward-based prioritisation cue. Across experiments, we found that both active and passive memory items were affected by interference to a similar extent, with overall performance being closely matched in all experiments. We further investigated precision and probability of target response parameters from the standard mixture model, which also showed no differences between states. We conclude that active and passive items, although potentially stored in different neuronal states, do not show differential susceptibility to interference. ### Competing Interest Statement The authors have declared no competing interest.

How does prior knowledge affect the way we experience the world?

In our new paper, we show that prior knowledge can both increase and decrease how often experience is segmented into events.
