Doing SDT via GLMMs is probably one of my favorite types of modelling - it was the first, relatively simple, example of doing generative stuff and inferential stuff in the same model, and not the classic two step "get estimates and -then- throw them in an ANOVA".

I remember being confused by always having to aggregate data (to means, counts, etc) in grad school. I think we've gotten much better at that with multilevel models etc, and here's another paper making this point well about analysing binary judgment data.

New 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.”

“Overall, GLMMs are a theoretically sound and practically robust method and thus superior for analyzing binary judgments in social and cognitive psychology.”

nice work, @semihaktepe.bsky.social @danielheck.bsky.social

Actually, we recently spooked away some ghosts with warnings and other scary things (with @semihaktepe.bsky.social)

"Revisiting the effect of discrepant perceptual fluency on truth judgments" tinyurl.com/2eepue5y

--> Two experiments & a meta-analysis indicate that high visual contrast does not lead to higher truth judgments.

How does plausibility shape the truth effect?

In our new paper with @danielheck.bsky.social, we propose a Bayesian model specifying how repetition and plausibility jointly influence binary truth judgments in light of nonlinear transformations.

We could not replicate the effect that higher color contrast results in higher truth judgments in two online experiments (N=98 and N=294).

We have a new reproduction. Siepe et al. reproduce: "A systematic review and Bayesian meta-analysis of the acoustic features of infant-directed speech" by Cox et al. @naturehumbehav.bsky.social. Full report below.

We (matzekloft.bsky.social, Semih Aktepe, @danielheck.bsky.social) recently participated in a robustness reproduction of articles in Nature Human Behaviour. It was a nice learning experience to check the reproducibility of others' code and to think about useful additional robustness analyses
