New paper out now asks: Why do we bother remembering *how* we learned something? With @antoniafl.bsky.social, Dilara Keşşafoğlu, Winuss Mohtezebsade, @celestekidd.bsky.social, Aylin Küntay, @janengelmann.bsky.social, and Bahar Köymen dx.doi.org/10.1037/dev0...

New episode!! 📣🎙️ A conversation w/ @renemottus.bsky.social about the science of human personality. The "Big Five" model of human personality has been enormously generative and influential. But what does it miss? What does it mask? Where should the field go next? Listen: disi.org/the-big-five...

New paper just dropped🎉 With novel "Curiosity Boxes", we find that chimps & children are very curious about social interactions, & some even give up a reward to gain info! Fun collaboration with @alisongopnik.bsky.social, @janengelmann.bsky.social & others royalsocietypublishing.org/doi/10.1098/...

New lab preprint (presented last Sunday as a VSS talk) from Zekun Sun: "Dissociating low-level visual features from high-level event structure in action segmentation" osf.io/preprints/ps...

New preprint w/ @christophvoelter.bsky.social et al. Individual differences in great ape cognition across time and domains: stability, structure, and predictability 48 apes 🦍, 10 tasks 🧠, 10 sessions📊, 1.5 y📅 ✅ Stable individual traits ❌ No g-factor 🤝 Social ≠ non-social 🔗: osf.io/preprints/ps...

UC San Diego Psychology hosted the first Southern California Meeting for Investigations in Developmental Science (SoCal MInDS) this Saturday. We were joined by wonderful folks from the southernmost UC campuses, SDSU, CSULA, Occidental College, and USC.

We're still accepting apps for our research scientist position with LEVANTE (levante-network.org). This position is ideal for folks wanting to be the interface between a cool scientific project and an awesome team of software developers. Think of it as a technical product manager, but for science!

bit of good news: approved technical staff position! link below. please be in touch if this matches your skills & interests! drive.google.com/file/d/16J2J... (hr listing posted harvard-internal now; external soon, per guidelines), happy for ?s & plan on quick turnaround! #CogSciSky #PsychSciSky 🐦🐦

Our R01 was part of yesterday's "mass termination" at Harvard; 1 of ~1000 NIH grants in Trump's "fight". The irony of how many Jewish (& non-Jewish) researchers/scientists/physicians/patients/students will be harmed in the name of "fighting antisemitism" is sickening.deliberately cruel. #AcademicSky

Looking at Van Gogh’s Starry Night, we see not only its content (a French village beneath a night sky) but also its *style*. How does that work? How do we see style? In @nathumbehav.nature.com, @chazfirestone.bsky.social & I take an experimental approach to style perception! osf.io/preprints/ps...

What motivates people to take action and share info about climate change? We tested 17 psychological interventions in a tournament—Discover the winners in our new paper! Out now in @pnas.org w/ @falklab.bsky.social, @michaelemann.bsky.social, & team. Thread ⤵️ 1/9 www.pnas.org/doi/10.1073/...

My book reveals the mostly hidden effects of talking *on talkers.* Talking boosts focus & learning, regulates emotions, changes perception, & more. The reason lies in how utterance planning for talking works. It's a book for gen'l audiences, but w scientific claims for production & its consequences

A few highlights from my "time tools" paper in 🧵 below. First, up "mountain calendars"...

How are humans able to make sense of time? Not with special biology but with “time tools”—ideas, practices, and artifacts that render time more concrete. My new paper explores this vast, varied toolkit—one that makes use of knots, nuts, hands, flowers, mountains, shadows, and much more. (link 👇)

1/ New Preprint (also my first time posting on BlueSky haha)!!! How do individual differences in habituation shape dishabituation magnitude? Work with Qiong Cao, @mcxfrank.bsky.social and @shariliu.bsky.social osf.io/preprints/ps...

Wanted to share a handy little resource with you all (especially those in dev psych) — my lab & I made a "journal submission cheat sheet" that summarizes article types, word limits, & other requirements for the journals we typically submit to. Link below 👇🏼 docs.google.com/spreadsheets...

A lot of students are not sure what career they want to pursue. To help with this, we've started recording videos with lab alumni in different careers and grad programs. Links below. Hope your students find them helpful! #STEM #ADVISING

Out now in @cp-trendscognsci.bsky.social from me, @mzettersten.bsky.social, & @ruthefoushee.bsky.social - 'Helpless' infants are active, goal-directed agents www.sciencedirect.com/science/arti... Cusack et al. propose 'helpless' human infants are "learning a foundation model" (à la SSL). We say,

Six months ago, I accepted a postdoc offer in a fabulous lab. Three days ago, the Trump administration terminated the NSF grant supporting the position. Today, my offer had to be rescinded, and my PhD defense is a week away. (1/3)

yesterday, my postdoc funding (salary and research funds) was cancelled by the National Science Foundation, effective immediately. I received the same generic, vaguely threatening, typo-ridden email as many of my colleagues who have had their awards terminated recently. (1/n)

As a psych undergrad in St. Petersburg 6 years ago, I never imagined I’d be starting my own cognitive science lab at one of the world’s best research environments. I’m beyond excited to share that I’ll be starting a Cognitive Epistemology Lab at @BerkeleyPsych in Fall 2026!

@katrinamillerphd.bsky.social & I took a look at over 400 active National Science Foundation grants that got killed in the past few days. Here's our story (gift link) nyti.ms/4jp4aOx

- @elenacaltmann.bsky.social @marinabazhydai.bsky.social Karadağ & @gertwestermann.bsky.social (2025) dev'd & validated the Infant & Toddler Curiosity Questionnaire (ITCQ), a caregiver report to capture variance in early trait curiosity #EarlyYears #DevPsySky #infancypapers doi.org/10.1111/infa...

Join us in congratulating the rising stars of #CogSci 🌟 We're excited to introduce the 2025 Glushko Prize winners, and the fascinating research behind their work!

New R package almost birthed - SemanticDistance - computes two semantic distance metrics (experiential and embedding) for any rolling chunk size (ngram-to-ngram, word-to-word, turn-to-turn, ngram-to-word). You give it your language sample. It does the rest, including lemmatize and stopword omit

Excited for this project to be out, led by superstar @erinecampbell.bsky.social!

SIX YEARS after the initial blog post, this paper is finally published.. what a wild ride - the blog: bit.ly/3GbOqQa - original tweet thread: x.com/Nate__Haines... - published (open access) paper: doi.org/10.1037/met0...

New Peekbank preprint! A snapshot of what we've learned so far about developmental change in word recognition using the large-scale repository of infant eyetracking data we've been building (~ 2000 infants; ~3500 individual test sessions)

Super excited to submit a big sabbatical project this year: "Continuous developmental changes in word recognition support language learning across early childhood": osf.io/preprints/ps...

One major finding in our pre-print is that the journal ‘Fluoride’ publishes much larger effects than any other academic journal. Fluoride is published by the International Society for Fluoride Research which is run by anti-fluoride activists and hosts water defluoridation workshops. #metascience

Why do we not remember being a baby? One idea is that the hippocampus, which is essential for episodic memory in adults, is too immature to form individual memories in infancy. We tested this using awake infant fMRI, new in @science.org #ScienceResearch www.science.org/doi/10.1126/...

Babies learn best from those who respond to their babbling! 👶✨ @juliaavenditti.bsky.social, @mikehgoldstein.bsky.social et al. (2025): infants form stronger social expectations when their babbling gets a timely response—even from a robot car! 🤖🚗 #infancypapers #EarlyYears doi.org/10.1111/infa...

Suppose you generated a sequence of 100 random numbers. Then one year later, you did it again. Do you think we could predict one sequence from the other? It turns out, we can! Now in press @ JEP:G with @samiyousif.bsky.social @actlab.bsky.social @robbrutledge.bsky.social; osf.io/preprints/ps...
