Thank you for sharing. In another study, we found that better virtual reality (VR) players are more intelligent (correlation, no causation). link.springer.com/article/10…
Games & fluid intelligence:
⌨️Performance in MOBAs like League & Dota correlates with intelligence
🎮Performance in FPSs like Battlefield 3 don't show the same pattern
🏙️ In a separate small study, good Civilization V players are better planners, organizers & problem-solvers

We recently published a paper in @NatureComms showing that minor behavioral interventions (message framing) can boost the adoption of solar panels (by up to 40%).

Schöner Beitrag über unsere Studie zu Mausbewegungen und Online-Betrug.
🖱️Onlinebetrüger können durch ihre Mausbewegungen identifiziert werden. Das ergab eine Studie eines internationalen Forschungsteams unter Beteiligung von Professor @markusweinmann @ciis_uoc

This is a great cheat sheet if you are interested in analyzing reaction times. #rstats
I've made a cheat sheet and a bunch of applets to give you an intuitive feel for various reaction time distributions. You can choose datasets, fiddle with parameters, and see working code examples: lindeloev.net/shiny/rt/ 1/n
What a great package. Produces Latex equations from R formulas (such as lme4). datalorax.github.io/equatiom… #RStats
Happy to be part of this project. Please have a look if you are interested in Open Science and it's various terms.
Interested in #Reproducibility and #OpenResearch but not sure what terms like #bropenscience, PARKing & WEIRD mean? @FORRTproject to the rescue!
Check out our new glossary, featured in @NatureHumBehav.

You find here some useful tips and packages for doing exploratory data analysis in R. towardsdatascience.com/four-… #RStats
This is a great idea.
I’ve been using #AnnotatedEquations in my recent papers. I think it really adds to the readability and understanding of the math.
Here are some examples. It uses #tikz in #latex.
Let me know if you like it. Happy for any feedback. [GitHub link: next tweet]
