New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵

Two-panel figure. Panel a is a flow diagram tracking 1,611 empirical psychology articles from publication year (545 in 2015, 552 in 2020, 514 in 2025) to repository-link type: 785 link an OSF project, 85 link another platform, and 741 link no repository. Of those with an OSF link, download counts were retrieved for 670 and not retrieved for 115. Panel b is a line chart of the share of empirical papers linking OSF across 2015, 2020 and 2025. The overall rate, shown as a dashed black line, rises from 9% to 57% to 82%. All four journals rise steeply and end close together: Psychological Science 92%, JESP 89%, JML 83%, Cognition 76%, with Psychological Science highest throughout.Three-panel figure. Panel a: ridgeline plot of downloads per file by material type on a log scale, with the percentage never downloaded labelled for each — archive 16% of 545 files, documents 20% of 2,970, code 12% of 3,471, other 17% of 1,646, data 21% of 10,051, media 35% of 2,120, images 35% of 4,102. Most files cluster between 1 and 10 downloads, with long right tails past 100. Panel b: ridgeline plot of downloads per paper by journal, log scale, with dashed median lines; Psychological Science is highest, then JESP, JML and Cognition. Panel c: stacked bars showing, for documents, data and code separately, the share of papers by download band (0, 1–10, 11–100, more than 100) in 2015, 2020 and 2025. The share exceeding 100 downloads falls sharply over time in all three types, from roughly two-thirds in 2015 to a quarter or less in 2025, as the 1–10 band grows.Four-panel figure. Panel a: statistical languages detected among 333 papers with retrievable code — R 88%, SPSS 12%, Stata 4%, SAS 1%. Panel b: code red flags among those 333 papers — 34% hard-code an absolute path, 40% reference a missing file — above documentation among 672 OSF-linked papers — 21% have a README, 30% are documented by README, description or wiki. Panel c: among 562 Elsevier papers with no repository link, 44% (245) host at least one journal supplementary file but only 14% (77) host data, code or an archive. Panel d: composition of those 448 hosted files — documents 52%, data 21%, media 9%, other 7%, archive 6%, code 3%, images 1%. The code panels are green, the journal-supplement panels blue.Coefficient plot (download predictors)

Dot-and-whisker plot of three standardised predictors of OSF download volume, each with a 95% confidence interval. Repository size (number of files) has the largest effect at about 0.76, citations about 0.38, and altmetric attention about 0.12. All three intervals sit entirely above zero, so each predicts more downloads, with repository size roughly twice the effect of citations and six times that of attention. X-axis: standardised effect, −0.2 to 1.0.

How do we prevent memories from competing to guide attention? More distinct hippocampal representations for competing memories are linked to precise preparatory coding in visual cortex & more accurate eye movements to target locations. Thrilled to share this work by the incomparable Serra Favila!

Writing this story was so unbelievably fun. And not only bc @mcxfrank.bsky.social says quotes like this: “Kids’ experience looks really radically different than we thought ... They’ve got these little short arms, so the objects are, like, right in front of them. And they live in a forest of knees.”

Good piece on why kids beat AI at learning, with Mike Frank and me. Behind a paywall but available elsewhere. www.technologyreview.com/2026/08/24/1...

I enjoyed writing this piece for The Transmitter. AI is a seismic change for science. What we make of it is up to us, but it’s a decision we can only make collectively. I hope more labs, and the field at large, will engage in finding a shared view of how we want to use AI.

With agentic AI’s rapid infiltration into science, researchers need to develop AI use policies and practices, writes @nicoschuck.bsky.social. #neuroskyence www.thetransmitter.org/artificial-i...

It has been painfully clear since Fall’24 that US science funding would tank, universities would be targeted, and any assertions about a new “gold standard” disingenuous. The question has not been “will it be that bad,” but “how bad will it be.”

US scientists: Going into fall 26, how are you thinking about things? Following Fall 24 events and a tumultuous spring 25, I remember a convo with a colleague in which we agreed we just needed to wait things out until fall 25 and we'd have some clarity about the landscape (eg for funding). /1

New paper out w/ Katherine Duncan and Morgan Barense! Why do some memories update when our expectations are violated, while others remain stable? What matters most is the strength of a memory at reactivation—not how old it is. And, I designed the cover! royalsocietypublishing.org/rstb/article...

Memory strength at reactivation, not memory age, governs prediction error-driven updating of naturalistic event memory

Abstract. Prediction error during memory reactivation is posited to be a key driver of memory updating. However, prediction error leads to varied memory ou

Scary stories about teens sell. The data tells a different story. After decades studying adolescent mental health, here's what I found: This isn't an anxious generation. It's a resilient one. Let's start treating them that way. go.ted.com/candiceodgers
