In conclusion, we show that the dynamic interplay between top-down control and bottom-up saliency directly impacts early visual responses, thereby illuminating a complete timeline of attentional competition in visual cortex.

Last, the greater the RIFT responses to the target compared to the distractor, the faster the participant responded to the target, demonstrating that the RIFT responses capture behaviorally relevant processes.

2) The presence of a distractor attenuated the initial RIFT response to the target, reflecting competition during the initial stages of visual processing

For conditional comparisons of the RIFT responses, we found that 1)Both target and distractor evoked stronger initial RIFT responses than nontargets, reflecting top-down and bottom-up attentional effects on early visual processing. And RIFT responses to the distractor eventually be suppressed.

For tagging manipulation, we tagged target and distractor in distractor present condition, tagged target and one of the nontarget in distractor absent condition. And frequency-tagging manipulation successfully elicited corresponding frequency-specific neural responses

We found that the salient distractor captured attention on behavioral level

In this study, to determine how top-down and bottom-up processes unfold over time in early visual cortex, we employed Rapid Invisible Frequency Tagging (RIFT) while participants performed the additional singleton task.

Dynamic competition between bottom-up saliency and top-down goals in early visual cortex Task-irrelevant yet salient stimuli can elicit automatic, bottom-up attentional capture and compete with top-down, goal-directed processes for neural representation. However, the temporal dynamics und...

Rapid Invisible Frequency Tagging (RIFT) with a consumer monitor: A proof-of-concept Rapid Invisible Frequency Tagging (RIFT) enables neural frequency tagging at rates above the flicker fusion threshold, eliciting steady-state responses to flicker that is almost imperceptible. While R...

🚨 New preprint: Invisible neural frequency tagging (RIFT) for the underfunded researcher:
👉 www.biorxiv.org/cgi/content/...

RIFT uses high-frequency flicker to probe attention in M/EEG with minimal stimulus visibility and little distraction. Until now, it required a costly high-speed projector.

Anticipated Relevance Prepares Visual Processing for Efficient Memory-Guided Selection Finding an object typically involves the use of working memory to prioritize relevant visual information at the right time. For example, successfully detecting a highway exit sign is useless when your...

Excited to present at #ECVP2025 - Monday afternoon, Learning & Memory - about how anticipating relevant visual events prepares visual processing for efficient memory-guided visual selection! 🧠🥳

Excited to give a talk at #ECVP2025 (Tuesday morning, Attention II) on how spatially biased attention during VWM does not boost excitability the same way it does when attending the external world, using Rapid Invisible Frequency Tagging (RIFT). @attentionlab.bsky.social @ecvp.bsky.social

Excited to share that I’ll be presenting my poster at #ECVP2025 on August 26th (afternoon session)!

IRL/CAP-Lab meeting

I had loads of fun today, sharing thoughts and projects during a joint lab-meeting with @nadinedijkstra.bsky.social's Imagine Reality Lab. Two hours were way too short to discuss all the cool projects!

Thanks everyone for your contributions 💜

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.

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"! 🧠🔍

📍 Location: Trippenhuis, Amsterdam

Through experience, humans can learn to suppress locations that frequently contain distracting stimuli. Using SSVEPs and ERPs, this study shows that such learned suppression modulates early neural responses, indicating it occurs during initial visual processing.

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!

Thanks for the recommendation! Really nice paper!

Many thanks to my co-authors! ❤️❤️

In conclusion, observers can flexibly de-prioritize and re-prioritize VWM contents based on current task demands, allowing observers to exert control over the extent to which VWM contents influence concurrent visual processing.

In the end, we found no evidence that the influence of non-prioritized memory items on early visual processing differs between the three experimental paradigms. And we found non-prioritized memory items influence early visual processing when we combined the data from three experiments.

In Experiment 3, we also found that only prioritized memory items influenced early visual processing in terms of the allocation of spatial attention.
