🚨New preprint🚨: Attitude measures like the IAT reveal biased behavior — but the levels across which bias operates are varied. Our new preprint borrows formal modeling approaches from perceptual science to find out where age-valence interactions happen in perceptual processing🧵

feel free to ask me Qs! im in the midst of converting my lab from qualtrics to pavlovia surveys. i will also be holding a local workshop in Toronto for those interested in learning more :)

Thank you to @rondalo.bsky.social for introducing Pavlovia Surveys to @canadianpsychology.bsky.social at #CPA2026 ! Are you searching for a low-cost flexible online survey tool? Check out Rondas slides and materials here! 👇 osf.io/rs6mg/overview

A screen show of an opening slide that reads "Pavlovia Surveys: A low-cost and flexible online survey tool. Dr Ronda Lo Toronto Metropolotan University"

Making open-sourced stuff last in perpetuity, finding long-term funding models, stewardship, etc is all hard, but worthwhile when the tool serves the community (whatever community that is) Hoping to have some progress on this score regarding jsPsych in the next while btw

Lol forgot the one I'm most involved with: for deploying surveys and experiments online, jspsych (free community-run OSS) vs $$ stuff like Qualtrics, e-prime, SurveyMonkey, Gorilla etc

many other examples in science, like Python vs Matlab, R vs SAS/Stata/SPSS/etc; public-good services like Zenodo, OSF, Zotero vs commercial alternatives; even document creation via Quarto/Rmd/LaTeX vs. Microsoft Word

Incidentally, collective action against bad actors, by creating alternative services that work well, is among the most hopeful things about technology academics creating open-access alternatives to Elsevier, libraries creating local alternatives to Spotify that pay musicians fairly, vibes are good

27. MOOD MACHINE (Liz Pelly @lizpelly.bsky.social). A truly excellent, deeply reported history of music streaming & its effects. Elegantly written throughout. learned a lot, was touched to hear of libraries spinning up open-source streaming services (akin to scientists taking on monopolists w/ OSS)

Cover of MOOD MACHINE by Liz Pelly

I put together a short slidedeck on specifying random effects in mixed models. This doesn't cover all possible edge cases, but I think this provides some basic best practices for proper generalization and uncertainty in estimation. Feedback is welcome! #stats #MLM #HLM #LMM #MEM (did I miss any?)
