Now out in #ScienceAdvances: @baiweiliu.bsky.social and I ask how internal (goal) and external (sensory) selection are coordinated during visual search. The key insight: internal and external selection are not inherently serial, but may develop in parallel in the human brain: doi.org/10.1126/scia...
Concurrent selection of internal goals and external sensations during visual search
Internal and external selection processes can codevelop in time to yield efficient search behavior.

Conrad Hal Waddington was born OTD in 1905.
His “epigenetic landscape” is a diagrammatic representation of the constraints influencing embryonic development.
On his 50th birthday, his colleagues gave him a pinball machine on the model of the epigenetic landscape.

In an EEG study spearheaded by Marlena Baldauf, we show that 8-month-old babies’ visual systems resonate at 4Hz (theta rhythm) — unlike adults, who resonate around 10Hz (alpha).

Can infants tell when your phone is getting in the way? 📱👀 Cao et al. (2025) found that 20mo infants expect adults distracted by phones to do worse at simple tasks. Even babies may realise the consequences of multitasking! #infancypapers onlinelibrary.wiley.com/doi/10.1111/...
