A "frontier" RCT showing college students preferred LLM (ChatGPT-4) and peer feedback to teacher feedback, but teacher feedback most improved performance. I hope they analyze feedback for style. I wonder whether students positively responded to sycophancy in LLM. #PsychSciSky #AcademicSky #EduSky
Teacher, peer, or AI? Comparing effects of feedback sources in higher education
With the emergence of Large Language Models (LLMs), AI-generated feedback is gaining traction as a scalable feedback source for higher education. To q…

1st day of #MITNB meeting at @tesc-tilburgu.bsky.social. Excited for the week ahead, where we'll tackle measurement issues in #ESM, e.g. modeling processes across timescales, building a formal theory on measurement, and evaluating statistical assumptions in #ESM data.

Damn, what an effort! 💪
We built the openESM database:
▶️60 openly available experience sampling datasets (16K+ participants, 740K+ obs.) in one place
▶️Harmonized (meta-)data, fully open-source software
▶️Filter & search all data, simply download via R/Python

🚀 50,000+ Android downloads!
What began less than five years ago with a simple “hello world” has grown into a trusted platform supporting researchers and clinicians across the globe in capturing the richness of daily life.
We feel deeply thankful (and a little proud too). 💙

When we measure personality multiple times in a study, does it matter if we ask people about their personality *in general* or *since the last time point*?
Turns out: yes!
We found differences in internal consistency, Ms, & SDs but not in the underlying constructs 🧵

Intervening on a central node in a network likely does little given that its connected neighbors will "flip it back" immediately. Happy to see this position supported now.
"Change is most likely [..] if it spreads first among relatively poorly connected nodes."

🚨 New preprint: We compared 13 methods for detecting momentary careless responding in the WARN-D data (206k+ obs.). Tutorials guide you through each method. The takeaway? Diverging results, inherent subjectivity (to varying degrees), and a clear need for further validation.
