Past experiences shape current selection. But when and how strong are past and present targets represented in the brain? In our newest paper, we show that past and present search targets are concurrently represented in the brain. Out now in @plosbiology.org doi.org/10.1371/jour... #neuroscience

Good morning @ecvp.bsky.social! ☕If you are wondering how imagery and perception interact and compete, and how to quantify these competitive interactions in visual cortex with fMRI,🧠please drop by the poster session this afternoon and chat with me about my newest study (with @peelen.bsky.social)

Now out at PNAS - congratulations to Ramanujan Srinath and the team! Ram's ability and willingness to connect all these data, models, and ideas has changed my thinking/interpretation of many findings. I suspect I will keep learning from this study for a long time. www.pnas.org/doi/10.1073/...

New preprint ! 🎺 👇 We show that objects can facilitate scene recognition irrespectively to their semantical link to the scenes. TMS to Object-selective LOC eliminated such facilitation! Congratulations to Aaron for his first paper coming from a chunky master thesis project!

How do we keep up with the pace of our surroundings? Previously, we’ve shown that working memory encoding speeds up when you expect limited encoding time. How does the brain accomplish this? In new work, we found that the brain uses an accelerated neural code⚡🧠: www.biorxiv.org/content/10.6... (1/6)

New preprint (doi.org/10.64898/202...) shows that where you look next is an economic decision. Saccades trade off effort-costs (measured via pupil) against monetary rewards. 1) By default, participants have strong saccade direction preferences (e.g., cardinal over diagonal, up over down) (1/4)

Reward and intrinsic effort-costs drive saccade selection 👀. But what happens when these factors compete? Our newest preprint shows that saccade selection follows principles of economic decision-making:

We often fail to pay attention to what's important for extended periods of time. What's going on in the brain when we're failing to pay attention? In a new preprint, we show that frontal potentials (fP3) track visual and auditory attentional lapses. doi.org/10.64898/202... #neuroscience

New paper out: Trial-level sequence modeling reveals hidden dynamics of dual-task interference. We decoded, at the trial level, the sequence of cognitive operations people take when multitasking. We found that how cognitive operations interleaved across tasks predicted RT and accuracy!

Investigations into whether we can search for multiple targets in a simultaneous fashion have led to mixed findings. In this new PsychScience article, we report that people CAN search concurrently, but don't always DO so... 🧵 journals.sagepub.com/doi/10.1177/...

What do we look for when searching for objects in our daily-life environments? Very happy that I can now share this review, together with @suryagayet.bsky.social , @predictivebrain.bsky.social and @peelen.bsky.social🥳 A brief thread below!

New paper alert: very proud to share our review published in Trends in Cognitive Sciences, spearheaded by @maellelerebourg.bsky.social, and together with @peelen.bsky.social and @predictivebrain.bsky.social, about goal-directed search in real-world environments. See below for a thread/tldr!

Do you want to measure pupil size while participants move their eyes around 👀? We offer a straightforward solution to gaze-induced distortions on pupil size measurements in our newest paper!

We show that synesthesia is sensory and automatic in nature: the pupil scales with the brightness of experienced synesthetic colors. doi.org/10.7554/eLif... Now in its new dress @elife.bsky.social (convincing & valuable in round 1). If anyone wants to pick up the method, happy to share & explain!

Hey bluesky 👋 really excited about this one! 👀

My first TEDx talk just came out. It's always fun to talk about your own research area to the general audience, and its even more fun when you are lucky enough to be supported by such a platform. Happy to hear your thoughts :-) youtu.be/UyUclyHx8d8?...

Celebration time 🥳 @liangyouzhang.bsky.social publishes the 1st empirical paper of his PhD! We show that numerosity adaptation (a seemingly high-level stim property) suppresses neural responses in early visual cortex; these adaptation FX increase as we progress thru the visual processing hierarchy.

This paper is now published in Journal of Neuroscience! www.jneurosci.org/content/earl...

Planning on running a RIFT study? In a new manuscript, we put together the RIFT know-how accumulated over the years by multiple labs (@lindadrijvers.bsky.social, @schota.bsky.social, @eelkespaak.bsky.social, with Cecília Hustá and others). Preprint: osf.io/preprints/ps...

🧠 Regularization, Action, and Attractors in the Dynamical “Bayesian” Brain direct.mit.edu/jocn/article... (still uncorrected proofs, but they should post the corrected one soon--also OA is forthcoming, for now PDF at brainandexperience.org/pdf/10.1162-...)

1/ Why are we so easily distracted? 🧠 In our new EEG preprint w/ Henry Jones, @monicarosenb.bsky.social and @edvogel.bsky.social we show that distractibility is associated w/ reduced neural connectivity — and can be predicted from EEG with ~80% accuracy using machine learning.

Very excited to announce my first paper is out in @currentbiology.bsky.social! Using EEG, we identify an item-based measure of storage in working memory that generalizes across auditory and visual items. authors.elsevier.com/a/1ljFF3QW8S... #PsychSciSky #neuroskyence #workingmemory

Surely you know about eye dominance. You probably don’t know it’s not a unitary phenomenon: in this paper I show that sensory eye dominance varies over the visual field. In the Discussion I propose an explanation for why this variation might exist. Curious? Read it here: doi.org/10.1167/jov....

Had a blast at last week's symposium! Inspiring to hear all the talks about EEG and attention. I presented on the neural correlates of saccade preparation and covert spatial attention. Check out the preprint here: doi.org/10.1101/2025...

Last week's symposium titled "Advances in the Encephalographic Study of Attention" was a great success! Held in the KNAW building in Amsterdam and sponsored by the NWO, many of (Europe's) leading attention researchers assembled to discuss the latest advances in attention research using M/EEG.

In this new preprint, in review @elife.bsky.social, we show what processing steps make up the reaction time using single trial #EEG modelling in a contrast #decision task. In this 🧵 I'm telling the story behind it as I think it is quite interesting and I can't write it like this in the paper...

Thrilled to share that I successfully defended my PhD dissertation on Monday June 16th! The dissertation is available here: doi.org/10.33540/2960

New paper out at Journal of Memory and Language! We knew that individual differences in working memory predict source memory, but did it predict simple item recognition memory (that relied on less attention resources than source memory)? Our answer is: YES! (with @edvogel.bsky.social ) 1/5

Now published in Attention, Perception & Psychophysics @psychonomicsociety.bsky.social Open Access link: doi.org/10.3758/s134...

Thanks to the support of the Dutch Research Council (NWO) and @knaw-nl.bsky.social , we're thrilled to announce the international symposium "Advances in the Encephalographic study of Attention"! 🧠🔍 📅 Date: June 25th & 26th 📍 Location: Trippenhuis, Amsterdam

Sensory sensitivity We study how people react to sensory input like lights and sounds. You can help by completing a short online questionnaire. You can also sign up for an optional 3-hour lab session in Utrecht (€12/ hour) involving EEG and hearing tests. Take the survey here: tinyurl.com/457z89ta

Long overdue! Didn't promote this one amid twitter/X chaos. But nearing the end of my PhD, I want to do this project justice and post it here: Is visual working memory used differently when errors are penalized? Out already 1+ year ago in JEP:LMC: research-portal.uu.nl/ws/files/258... 🧵 (1/3)

Good morning #VSS2025, if you care for a chat about the role of attention in binding object features (during perceptual encoding and memory maintenance), drop by my poster now (8:30-12:30) in the pavilion (422). Hope to see you there!
