- Reposted by Henrik Singmann🚨New paper altert🚨 As a synthesis of my PhD research, we revisited the prevailing assumption about the mechanisms underlying repetition learning, and re-evaluated these assumption in light of recent findings. Now out in Perspectives on Psychological Science: doi.org/10.1177/1745...
- Reposted by Henrik SingmannNew draft: "Decline effects, statistical artifacts, and a meta-analytic paradox". In this manuscript I show how a common practice in meta-analysis (eg the 2015 Open Science Collaboration) creates artifactual signatures of poor scientific behavior.

- Reposted by Henrik SingmannYou can test new tech ideas using the Seinfeld Test Would the product eliminate the plot of an episode? (Google maps, cell phones, paypal, battery packs) Good tech. Would the product inspire new Seinfeld plots? (NFTs, AI chatbots, crypto currency, blindboxes, metaverse land sales) Bad tech.

- Reposted by Henrik SingmannFirst post of the year, new paper out today: we present possibly the biggest case of systematic Measurement Schmeasurement in tech use. It seems that most studies on gaming (videogame) addiction/disorder haven't measured gaming after all. This research took years, so long 🧵 doi.org/10.1098/rsos...
- Reposted by Henrik SingmannNew preprint by @semihaktepe.bsky.social 🎉 We compare ANOVA/SDT/GLMM for binary judgments in 20 datasets of the truth effect. #lme4 Main conclusion: "GLMMs are a theoretically sound and practically robust method and thus superior for analyzing binary judgments in social and cognitive psychology.”

- Reposted by Henrik SingmannMost popular decision-making models assume that cognitive processes are static over time. In our new paper in Psych Review, we offer a simple extension to evidence accumulation models that lets researchers account for systematic changes in parameters across time 📈 psycnet.apa.org/fulltext/202...

- The details of this paper post mortem are pretty shocking.
- As the new year is bringing only more of the mess of the last, I am reminded of this banger from ten years ago. Things should have been much cooler by now but instead we have tech billionaires in cahoots with increasingly right-wing governments: www.youtube.com/watch?v=R8ca...

In this registered report we find that higher WM load rarely impairs LTM encoding - suggesting WM capacity is not a bottleneck for forming LTM traces. @as-souza.bsky.social @edamizrak.bsky.social @cognition-zurich.bsky.social psycnet.apa.org/record/2026-...
