Marvin would like to officially thank all sponsors and partners of the ICA Hackathon 2026🐧 #HackICA26 would not be possible without you. Events like this are about much more than coding alone. They are about creating connections, lowering barriers, and building a supportive research community.

Greetings from the beach, hacker friends! Marvin here with a little postcard while I prep for #hackica26 🐧🌊 Started planning your time in Cape Town yet? 🏄 Exploring the beaches 🌄 Visiting Table Mountain 🌿 Discovering nature ☕ Wandering around the city Or something else? Let me know! 👇

Also today at #SANS2026, Ziyu Zhao investigates the “brain rot” hypothesis. When studied rigorously, in large multi-national samples, we find a whole lot of nothing. Conclusion: previously observed alarming results might be driven by sampling bias and/or measurement error (P1-C-20)

Research poster by Zhao, Fisher, Parry, and Huskey presenting a large-scale, multi-site, pre-registered study on TikTok use and attention. Key finding: near-null effects on executive control and orienting; TikTok users show higher alerting efficiency than non-users, suggesting a stimulus-reactive attentional profile rather than impairment.

🚌 Beep beep! Important Info for all participants of #HackICA26 Marvin’s free shuttle service will operate on both event days between Convention Square (CTICC) and Stellenbosch University. 🌅 Morning pickup (both days): between 07:30 and 08:00 a.m. 🌃 Return to Cape Town (both days): After the event

Hi dear hacker friends, it's Marvin again! 🐧 I just wanted to give you a quick reminder to register for this year’s Hackathon in Cape Town. In this year's logo you can spot two of my favorite things: the ocean 🌊 and the King Protea 🌺, South Africa’s national flower. Register here: lnkd.in/dd9usKpE

How do we deal with rich, multilevel, and multimodal data? In a new preprint, @rachaelkee.bsky.social and I sketch an answer! For all the details, and the preprint link, see Rachael’s thread. Be sure to give her a follow, especially if you’re interested in neuroscience, sleep, and media!

Three-panel infographic illustrating Marr’s Levels of analysis in a study of repeated exposure to crime media.
(a) At the top left, a diagram labeled “Marr’s Levels” shows three stacked boxes: 1. Computation (why / problem) in orange, 2. Algorithm (what / rules) in coral, and 3. Implementation (how / physical) in dark red.
(b) At the top right, an illustration of a person looking at a smartphone surrounded by social media icons, a warning symbol, and a clock, labeled “Repeated exposure to crime media.”
(c) The bottom row maps each level to research methods: Computation shows a person with checklist icons and the text “EMA/ESM surveys, in-app surveys, pop-up questionnaires.” Algorithm shows a smartphone social media interface with the text “Digital trace data, smartphone usage logs, screen time APIs.” Implementation shows a person interacting with a smartwatch and the text “Wearable biometric sensors (e.g., smartwatches, Oura ring), consumer-grade EEG (e.g., MUSE headbands), eyetracking devices (e.g., Gazepoint GP3).”

🚨 New Preprint Alert 🚨 Communication science has no shortage of data. But what do we do with all of it? Experience sampling, sensors, digital trace, location aware observations are growing in popularity and scale.
