The Effects of Anticipating Metacognitive Judgments about Mind-Wandering - Attention, Perception, & Psychophysics Across two experiments (N = 121, 121) we examined whether the anticipation of metacognitive judgments in the form of experience sampling probes of mind-wandering influenced attentional engagement. Par...

New research from University of Waterloo Psychology researchers Adrian B. Safati (PhD student) and Dr. Daniel Smilek shows that simply expecting to think about our own thinking can actively influence how we regulate attention. Check it out: link.springer.com/article/10.3...

That is so exciting!!! Wow congratulations!!!

Can We Process Information Without Encoding It into Working Memory?

Our findings with @gidon-frischkorn.bsky.social and @koberauer.bsky.social suggest that processing entails encoding. Task-irrelevant information enters working memory during processing, impairing memory for relevant information.

How Small Is Small Enough? Understanding Negligible Effects Researchers often ask questions about whether an effect is small enough to be considered unimportant. For example, is the difference in productivity between working at home and working in the office n...

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.

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...

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.

Infant Brains Tick at 4Hz - Resonance Properties of the Developing Visual System Neural rhythms of the infant brain are not well understood. Testing the rhythmic properties of the adult visual system with periodic or broadband visual stimulation elicited neural resonance phenomena...

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/...

Awesome! Do you mind if I get your email and we can coordinate a pick up time?

Where can I pick one up? We would love to have one if someone else hasn’t snagged them!

Awesome! I’m waiting to see what my PIs think. If someone else wants them before I get back to you then no worries!!

Sorry for the late response! Are they still available?
