Happy to announce my new preprint with
@Daniel_Heck : Modeling Dependent Group Judgments: A Computational Model of Sequential Collaboration
The developed model is consistent with previous findings and we also confirmed new prediction from the model!
Finally out at PNAS https://pnas.org/doi/10.1073/pnas.2220580120!
Lab-identified Super-Recognizers also excel at identifying perpetrators on real-world CCTV footage from actual crime scenes.
Thank you Meike for having me in this amazing project!
Congratulations to @marenmayer 🥳 The 2nd paper of her PhD is now published in the Journal of Mathematical Psychology:
"Cultural consensus theory for two-dimensional location judgments"
Maren developed a Bayesian model for aggregating 2-dimensional judgments which infers:
(a) a group's consensus regarding the unknown locations for a set of targets (e.g., cities)
(b) the expertise of individuals

Welcome new arrivals #onhere. A few tips I learned:
1️⃣make a toot. Empty accounts are 😞
2️⃣ toot an Introduction. Whatever you want to say (work, personal, motivation for being here). Share Introductions. Pin it to your timeline 📍
3️⃣ boost generously 🎺 You are *not* on the 🐦site. No algorithm here. If you want others to see the toot, #boost
4️⃣ check out new folks; I found a lot of interesting new things.
5️⃣ Don’t auto crosspost from #twitter. It looks weird, no context.
HAVE FUN 🤩
Just published a preprint together with Meike Ramon (not yet on Mastodon):
Improving forensic perpetrator identification with Super-Recognizers
With 73 Super-Recognizers and 45 control participants, we show that SR are superior in perpetrator identification in authentic forensic CCTV footage. Moreover, SRs perform even better, the better their performance in tests and CCTV test sequences!
@marenmayer just submitted a revised paper:
Cultural consensus theory (CCT) for two-dimensional location judgments
https://psyarxiv.com/unhvc/
#CCT provides estimates of the shared, latent #consensus knowledge of a group of informants (similar to #WisdomOfCrowds), while accounting for heterogeneity in informant competence & item difficulty.
We develop a new CCT model for location judgments which are obtained when asking informants to locate a set of unknown sites on a map.
The lack of models in psychology hinders scientific progress. To start addressing this problem, we need a clear understanding of what models are and what they are not.
